background

the transperineal stepper is configured to drive the biopsy needle through the intended location of the perineum (i.e., the area between the patient's anus and the scrotum or vulva). A grid plate having a pattern or array of grid holes is positioned distal to the transperineal stepper to provide guidance for one or more biopsy needles. The transperineal stepper includes an ultrasound probe insertable into a rectum of a patient, a carriage configured to rotate the ultrasound probe to a plurality of angles during a procedure, and a base configured to move the ultrasound probe longitudinally. The grid plates may be attached to the transperineal stepper, and different kinds of grid plates may be used, which differ, for example, in pattern and hole size. The grid may be a reusable or disposable component. The ultrasound probe provides ultrasound images from within the patient's body and stabilizes the position of the transperineal stepper.

fig. 1A is a perspective view of a conventional transperineal stepping system 100, the transperineal stepping system 100 including a transperineal stepper 105 having an ultrasound probe 110, a base 150, and a grid 180 positioned in a conventional carriage 130. Fig. 1B is a rear plan view of a conventional transperineal stepper system 100 (as viewed from the proximal end of the transperineal stepper 105). The ultrasonic probe 110 includes: an elongated neck 112; at least one ultrasonic transducer 114 connected to the distal end of the elongated neck 112; and an elongated body 116 connected to the proximal end of the elongated neck 112. The grid plate 180 is shown to include an array of grid holes, such as needle guides through which needles may be placed. Although in fig. 1A and 1B, the grid panel 180 may appear to be a simple device, the grid panel 180 may be used in conjunction with other medical devices for medical procedures requiring particularly precise control of, for example, a biopsy needle. For example, as described above, the transperineal stepper 105 may be used with the grid plate 180 to drive a biopsy needle through the desired location of the perineum. The ultrasound probe 110 is configured to move longitudinally under the grid plate 180 for insertion into the rectum of a patient and to rotate by operation of the carriage 130 in order to acquire images from within the patient at different angles.

this rotation is achieved by rotating the ultrasound probe 110 about a center of rotation (first longitudinal axis) of the elongated neck 112 that is different from a center of rotation (second longitudinal axis) of the elongated body 116. That is, the first longitudinal axis is offset relative to the second longitudinal axis, making the design of the bracket 130 problematic. For example, the bracket 130 may reach a rotating window of about 90 degrees to about 160 degrees, but it is not very stable on the edges of rotation. Moreover, since the minimum diameter of the cradle 130 depends to a large extent on the geometry of the ultrasound probe 110, the minimum diameter is typically relatively large. When the carriage is rotated, particularly to the edge of the rotation, the relatively large diameter blocks the entrance to the grid plate 180, as shown in FIG. 1B, for example, thereby preventing insertion of a biopsy needle through the blocked hole.

Furthermore, the design of the bracket 130 is rather complex. To function properly, the bracket 130 requires tight tolerances in certain features where it is difficult to maintain manufacturing accuracy. Thus, the brackets 130 typically require fine adjustment screws and other adjusters that are problematic in terms of production and make each bracket 130, and thus each transperineal stepper 105, unique. Furthermore, smooth rotation of the carrier 130 is very sensitive to the torque generated when the elongated neck 112 is pushed in use. The design of the bracket 130 makes it quite difficult to design a rotating handle that will produce a smooth and accurate rotation. Moreover, in practice, the carriage 130 is difficult to clean and remains clean.

The carriage design may be replaced by a shaft design (not shown) that includes placement of a rotating shaft that engages the proximal end of the ultrasound probe 110 to provide rotation. However, cable management using shaft designs becomes problematic because the cable 119 for providing power and electrical signals to the ultrasound transducer 114 is attached to the proximal end of the ultrasound probe, thereby impeding the rotational motion of the shaft.

Accordingly, there is a need for a transperineal stepper with an efficient and easy to operate means for rotating the ultrasound probe without interfering with other aspects of the transperineal stepper operation, such as effective cable management or increased size.

Fig. 2 is a side view of an ultrasound probe for use in a transperineal stepper according to a representative embodiment.

Referring to fig. 2, the ultrasound probe 210 includes an elongated neck 212, at least one ultrasound transducer 214 connected to a distal end of the elongated neck 212, and an elongated body 216 connected to a proximal end of the elongated neck 212. The elongated neck 212 is insertable into a patient and rotatable about a first longitudinal axis 212 ', the first longitudinal axis 212' corresponding to a central longitudinal axis of the elongated neck 212. For example, the elongated neck 212 may be configured to be inserted into the rectum of a patient and rotated to a plurality of angles about the first longitudinal axis 212' to provide images with different views from the ultrasound transducer 214. In the depicted embodiment, the ultrasound transducer 214 is an ultrasound transducer array comprising a plurality of ultrasound transducers arranged generally in a row and column configuration, providing an illustrative image field 215. Of course, without departing from the scope of the present teachings. The ultrasonic transducers 214 may be implemented in a variety of numbers, types, and/or arrangements. The elongated body 216 is rotatable about a second longitudinal axis 216 ', which second longitudinal axis 216' corresponds to the central longitudinal axis of the elongated body 216. The second longitudinal axis 216 ' is parallel to the first longitudinal axis 212 ' and laterally offset relative to the first longitudinal axis 212 '.

the ultrasound probe 210 also includes a strain relief 217 and a cable 219 inserted through the strain relief 217. The strain relief 217 protects the mounting point of the cable 219 from stresses created by manipulating (e.g., pulling, pushing, and rotating) the ultrasound probe 210. The cable 219 travels through the strain relief 217 to enter an internal channel (e.g., internal channel 211 shown in fig. 3B) of the ultrasound probe 210 to provide an electrical connection with the (at least one) ultrasound transducer 214. In the depicted example, the cable 219 travels the length of the ultrasound probe 210 within the interior channel 211 to the ultrasound transducer 214. In an alternative configuration, the end of the cable 219 protrudes beyond the ultrasound probe 210, connecting to a combiner board (not shown) located inside the ultrasound transducer 214 that provides separate internal wiring.

Fig. 3A is a side view and fig. 3B is a cross-sectional view of an ultrasound probe and probe mounting structure attached to a rotating shaft for use in a trans-perineal stepper, according to a representative embodiment. Fig. 4 is an exploded perspective view of an illustrative probe mounting structure and rotating shaft for use in a trans-perineal stepper, according to a representative embodiment.

Referring to fig. 3A, 3B, and 4, the ultrasound probe 210 is attached to a probe mounting structure 230, and the probe mounting structure 230 is attached to the shaft 220. Thus, the shaft 220 is disposed at the proximal end of the elongate body 216 of the ultrasound probe 210. The probe mounting structure 230 includes: a support 233, the support 233 configured to receive the elongate body 216 of the ultrasound probe 210; and a clamp 235, the clamp 235 configured to mechanically secure the elongate body 216 in the support 233 such that the elongate body 216 is held in a fixed position relative to the probe mounting structure 230. In the depicted example, each of support 233 and clamp 235 has a concave shape to receive a generally tubular ultrasound probe 210. Of course, the support 233 and the clamp 235 may have alternative shapes to accommodate the specific shape of such an ultrasound probe connected to the probe mounting structure 230 without departing from the scope of the present teachings. Also, connection means other than pairs of supports 233 and clamps 235 may be incorporated without departing from the scope of the present teachings.

referring again to the depicted example, the probe mounting structure 230 also includes a flange 231 at its proximal end. The flange 231 defines apertures 236A and 236B that align with the apertures 226A and 226B in the distal end of the shaft 220. Aligned holes 236A/226A and 236B/226B receive screws 237A and 237B, respectively, to mechanically secure or attach shaft 220 to flange 231. As will be apparent to those skilled in the art, any other means of securely attaching the shaft 220 to the flange 231, such as bolts, rivets, clamps, or solder, may be used in combination without departing from the scope of the present teachings. Shaft 220 also includes a set of pins (pins 227A and 227B) extending from the proximal end of shaft 220. Pins 227A and 227B are used to attach shaft 220 to a handle (e.g., rotation handle 260 shown in fig. 8A and 8B) used to rotate shaft 220. As discussed below.

The shaft 220 is rotatable about a third longitudinal axis 220 ', the third longitudinal axis 220' corresponding to a central longitudinal axis of the shaft 220. In the depicted embodiment, the third longitudinal axis 220 'is parallel to and aligned with the first longitudinal axis 212' of the elongated neck 212. Rotation of the shaft 220 causes corresponding rotation of the probe mounting structure 230 and the attached elongate body 216 of the ultrasound probe 210 about the second longitudinal axis 216' to a desired position. Rotation of the elongated body 216 translates into rotation of the elongated neck 212 about the first longitudinal axis 212' to position the ultrasound transducer 214 at a desired angle for ultrasound imaging.

fig. 5 is a perspective view of the rotational axis of fig. 3A and 3B for use in a trans-perineal stepper, according to a representative embodiment.

Referring to fig. 4 and 5, the shaft 220 defines a longitudinal shaft channel 224 and a longitudinal shaft slot 225. A shaft passage 224 passes through the interior of the shaft 220 along the length of the shaft 220 (between the proximal and distal ends). The shaft slot 225 is parallel to the shaft channel 224 in the longitudinal direction along the length of the shaft 220 and also extends inwardly from the outer surface of the shaft 220 to the shaft channel 224 to enable access to the shaft channel 224. For example, the cable 219 may be inserted into the shaft channel 224 (and subsequently into the internal channel 211 of the ultrasound probe 210, as described above) by passing through the shaft slot 225 in the shaft 220. The shaft 220 also includes a hole 221 at the bottom of the shaft channel 224 to enable physical attachment to an operating handle (e.g., handle 260), as described below.

Thus, from the proximal end of the shaft 220, none of the cables 219 travels outside, thereby preventing the cables 219 from interfering with the movement of the ultrasound probe 210 and/or its support structure. That is, internally advancing the cable 219 through the shaft channel 224 improves cable management while manipulating the ultrasound probe 210 during a medical procedure. It is noted that although a single cable 219 is shown for purposes of illustration, it is understood that cable 219 may represent multiple (two or more) cables passing through the interior passage 211 of shaft 220 and providing a wired connection to the ultrasound transducer 214. The cable 219 may provide power to the ultrasound transducer 214 and/or exchange electrical signals with the ultrasound transducer 214.

Fig. 6 is a perspective view of an ultrasound probe for use in a trans-perineal stepper and a probe mounting structure attached to the rotational shaft of fig. 3A and 3B, according to a representative embodiment. It is to be noted that it is preferable that,

Fig. 6 also shows a shaft slot 225 in the shaft 220 for accommodating insertion of the cable 219.

Referring to fig. 6, the ultrasound probe 210 is attached to the probe mounting structure 230, and the probe mounting structure 230 is attached to the shaft 220. The ultrasound probe 210 includes an elongated neck 212 and an elongated body 216 disposed end-to-end, and at least one ultrasound transducer 214 (e.g., an ultrasound transducer array) 214, the at least one ultrasound transducer 214 being positioned at a distal end of the elongated neck 212 for providing an image field 215. The elongate body 216 is secured to a support 233 of the probe mounting structure 230 by a clamp 235. The probe mounting structure 230 is fastened or secured to the shaft 220 via a flange 231. The shaft 220 defines a shaft channel 224 and a shaft slot 225, wherein the shaft slot 225 exposes the shaft channel 224 to enable insertion of the cable 219 (via the shaft slot 225) into the shaft channel 224 and the internal channel 211 of the ultrasound probe 210. The cable 219 and/or wiring extending from the cable 219 travels within the internal channel 211 to the ultrasonic transducer 214 to provide an electrical power connection and/or an electrical signal connection.

fig. 7 is a perspective view of a rotating shaft and shaft housing for use in a trans-perineal stepper, according to a representative embodiment.

Referring to fig. 7, the shaft housing 240 is configured to receive the shaft 220. The shaft housing 240 defines a longitudinal housing slot 245, the longitudinal housing slot 245 alignable with the longitudinal shaft slot 225 in the shaft 220 to enable placement of the at least one cable 219 within the shaft passage 224. The shaft housing 240 is held in place by a housing frame 241, which housing frame 241 in the depicted embodiment is connected to a longitudinal translation means comprising rods 255, which rods 255 are configured to slide through respective longitudinal bores 256 in the base 250 of the trans-perineal stepper 250, for example by manually operating knobs 251. (another knob 251 (not shown) may be disposed on an opposite side of the base 250.) thus, longitudinal movement or sliding of the rod 255 through the corresponding bore 256 of the base 250 causes movement of the housing frame 241 and the housing 240 as a unit. This in turn causes corresponding longitudinal movement of the shaft 220 with the housing frame 241 and the housing 240, the probe mounting structure 230 attached to the shaft 220 via the flange 231, and the ultrasound probe 210 attached to the probe mounting structure 230 as a unit to the desired location. For example, longitudinal movement of the ultrasound probe 210 causes the elongated neck 212 to move within the patient for ultrasound imaging. The shaft 220 is rotatable within an otherwise fixed shaft housing 240, resulting in corresponding rotation of the probe mounting structure 230 and the ultrasound probe 210 attached to the probe mounting structure 230, as described above. This results in angular positioning of the ultrasound transducer 214 within the patient to obtain the desired ultrasound imaging.

Fig. 8A is a cross-sectional view of a rotation handle for operating a rotating shaft within the shaft housing shown in fig. 7 for use in a transperineal stepper, and fig. 8B is a perspective view of the rotation handle in fig. 8A for operating a rotating shaft for use in a transperineal stepper, according to a representative embodiment.

Referring to fig. 8A and 8B, an exemplary embodiment is depicted in which the rod 255 is caused to slide through the bore 256. In particular, the knob 251 is connected to a gear 252, the gear 252 having teeth adapted to mesh with teeth of a track 253 within the base 250. As the gear 252 is rotated clockwise (in response to movement of the knob 251), longitudinal motion toward the distal end of the base 250 is translated to the track 253, causing the ultrasound probe 210 to move toward or into the patient. When gear 252 is rotated counterclockwise, longitudinal motion toward the proximal end of base 250 is translated to orbit 253, causing ultrasound probe 210 to move away from or out of the patient's body. Of course, other mechanisms positioned in the base 250 or other locations may be incorporated to enable longitudinal movement of the assembly including the shaft 220, the probe mounting structure 230, and the ultrasound probe 210 without departing from the scope of the present teachings.

Additionally, as shown in fig. 8A, the shaft 220 includes a shaft passage 224, the shaft passage 224 containing the strain relief 217 and the cable 219. The shaft slot 225 of the shaft 220 (in the depicted neutral position of the shaft 220) is aligned with the housing slot 245 of the housing 240, the handle slot 265 of the handle 260 (discussed below), and the housing frame slot 242 in the housing frame 241. This alignment enables the cable 219 to be inserted into the shaft passage 224 through the aligned handle slot 265, housing slot 245, and shaft slot 225. Then, when the shaft 220 is rotated to various positions in the shaft housing 240, the shaft slots 225 may no longer align with the housing slots 245 (and the frame slots 242). However, once the cables 219 are within the shaft channel 224, it is no longer necessary to align the shaft slots 225 with the housing slots 245 and the housing frame slots 242, enabling easy cable management during operation of the trans-perineal stepper. Shaft 220 also includes axial pins 227A and 227B extending from the proximal end of shaft 220 and a hole 221 in the bottom of shaft 220 to enable attachment of shaft 220 to handle 260 via screw 261.

Fig. 8B is a perspective view of a rotational handle 260 for use in the above-described trans-perineal stepper, according to a representative embodiment. Referring to fig. 8B, the handle 260 surrounds both the shaft housing 240 and the shaft 220. In the depicted example, handle 260 is physically connected to shaft 220 by way of axial pins 227A and 227B extending through respective holes 267A and 267B through the proximal end of handle 260. The handle 260 is further connected to the shaft 220 by a screw 261 extending through the hole 221 of the rod 220. Of course, other methods of physically connecting the shaft 260 to the shaft 220 may be used in combination without departing from the scope of the present teachings. The handle 260 prevents the shaft 220 from sliding longitudinally within the shaft housing 240. Rotation of the handle 260 causes a corresponding rotation of the shaft 220 about the third longitudinal axis 220 ', which further causes the elongated neck 212 to rotate about the first longitudinal axis 212'.

the handle 260 defines the longitudinal handle slot 265 described above, which longitudinal handle slot 265 is alignable with the housing slot 245 and the frame slot 242, and with the shaft slot 225, thereby enabling placement of the at least one cable 219 in the shaft channel 224. Then, when the shaft 220 is rotated to multiple positions by operating the handle 260 within the shaft housing 240, the (co-rotating) shaft slot 225 and the handle slot 265 may no longer be aligned with the housing slot 245 (and the frame slot 242). In other words, the handle 260 defines a longitudinal handle slot 265, the longitudinal handle slot 265 being fixedly aligned with the longitudinal shaft slot 225 throughout rotational operation of the ultrasound probe 210, and with the longitudinal housing slot 245 (and the housing frame slot 242) in an intermediate position of the shaft 220. However, once the cables 219 are located within the shaft channel 224, it is no longer necessary to align the shaft and handle slots 225, 265 with the housing and frame slots 245, 242, so that cable management can be easily performed during manipulation of the trans-perineal stepper. Of course, means for rotating the shaft 220 and/or preventing the shaft 220 from sliding longitudinally within the housing 240 may be incorporated without departing from the scope of the present teachings.

Fig. 9 is a perspective view of a transperineal stepper having a rotational axis and attached grid plates including a transperineal stepper according to a representative embodiment.

Referring to fig. 9, a transperineal stepper system 900 includes a transperineal stepper 205 and a grid 180, the transperineal stepper 205 having an ultrasound probe 210 positioned in a probe mounting structure 230. The ultrasound probe 210 includes an elongated neck 212, at least one ultrasound transducer 214 connected to a distal end of the elongated neck 212, and an elongated body 216 connected to a proximal end of the elongated neck 212. The grid plate 180 is shown to include an array of grid holes, for example, which are needle guides through which needles may be placed. The transperineal stepper 205 also includes a shaft 220, the shaft 220 defining a shaft channel 224 and a shaft slot 225 (for accessing the shaft channel 224). The cable 219 of the ultrasound probe is placed in the shaft channel 224 through the shaft slot 225, enabling easy cable management during operation of the transperineal stepping system 900.

the transperineal stepper 205 also includes a handle 260, the handle 260 surrounding the shaft housing 240 and the shaft 220. Rotation of the handle 260 causes a corresponding rotation of the shaft 220 and, thus, the elongate neck 212 of the ultrasound probe 210, as described above. The handle 260 also prevents the shaft 220 from sliding longitudinally within the shaft housing 240. The handle 260 defines a longitudinal handle slot 265, the longitudinal handle slot 265 alignable with the housing slot 245 and the frame slot 242, and with the shaft slot 225 of the shaft 220, such that when all the slots are aligned, the at least one cable 219 can be placed in the shaft channel 224. When the shaft 220 is rotated to multiple positions by operating the handle 260 within the shaft housing 240, the shaft slot 225 and the handle slot 265 rotate together while the cable 219 remains within the shaft channel 224, enabling easy cable management during manipulation of the transperineal stepper 205.
