In this embodiment, before the instrument base 2 is hooked with the adapter plate 1, the hooking directions of the first connecting portion 211 on the posture linkage interface 21 and the second connecting portion 111 on the transition wheel 11 are the same, and after the four first rounded portions 22 on the instrument base 2 are respectively in one-to-one correspondence with the four second rounded portions 124 of the plate body 12, the first connecting portion 211 and the second connecting portion 111 are just in correspondence, but no hooking engagement is formed yet, and at this time, after the instrument motor performs reciprocating rotation movement in a small range according to the characteristics of the tail end of the instrument, the first connecting portion 211 and the second connecting portion 111 are automatically buckled and hooked.

Alternatively, as shown in fig. 2 and 3, one of the first connection portion 211 and the second connection portion 111 is a protrusion structure, and the other is a groove structure.

In this embodiment, a groove structure may be selectively provided on the transition wheel 11, a protrusion structure may be provided on the posture linkage interface 21, or a protrusion structure may be selectively provided on the transition wheel 11, and a groove structure may be provided on the posture linkage interface 21. For reference, examples in which the first connection portion 211 is a groove structure and the second connection portion 111 is a protrusion structure are given in fig. 2 and 3, respectively. In this way, the first connection portion 211 and the second connection portion 111 are respectively configured to be one of a groove structure and a protrusion structure, and the insertion fit of the groove structure and the protrusion structure is utilized to realize the insertion connection between the first connection portion 211 and the second connection portion 111, so as to simplify the structure of the posture linkage interface 21 and the transition wheel 11, and facilitate production and manufacturing.

In this embodiment, the protrusion structure includes two column structures, i.e., a first column and a second column, and correspondingly, the groove structure also includes two grooves, i.e., a first groove 2111 and a second groove 2112. When the first cylinder and the second cylinder are inserted into the first notch 2111 and the second notch 2112, respectively, the attitude linking joint 21 and the transition wheel 11 are just hooked and do not rotate relatively. When the first cylinder and the second cylinder are cylinders, at least two cylinders are required to be inserted into the groove structure to prevent the posture linkage interface 21 and the transition wheel 11 from rotating relatively after being hung; when the first column and the second column are prisms, one column may be provided to prevent the posture linkage interface 21 and the transition wheel 11 from rotating relatively after being hooked, and two or more columns may improve the stability of the connection between the first connection portion 211 and the second connection portion 1211.

Optionally, the first and second grooves 2111, 2112 are located in the same radial direction of the attitude linkage interface 21.

For ease of hooking, the attitude linking interface 21 is generally configured as a circular interface structure, and in this embodiment, the first notch 2111 and the second notch 2112 are located on the same diameter of the attitude linking interface 21. Thus, the hooking between the attitude linking interface 21 and the transition wheel 11 can be further facilitated.

Optionally, the first and second grooves 2111 and 2112 are one of a slit configuration and a kidney-shaped groove configuration, respectively.

In the actual production process, in order to facilitate assembly, the transition wheel 11 and the mounting groove 121 (described later) are in clearance fit, so that when the attitude linkage interface 21 is hooked with the transition wheel 11, a certain deviation exists between the first connecting portion 211 and the second connecting portion 111 in the radial direction of the transition wheel 11 or the attitude linkage interface 21, so that the insertion cannot be formed, and the hooking cannot be performed. Therefore, in this embodiment, the first groove 2111 and the second groove 2112 are respectively configured as one of an opening structure and a kidney-shaped groove structure, that is, the first groove 2111 is an opening structure, the second groove 2112 is a kidney-shaped groove structure, or the first groove 2111 is a kidney-shaped groove structure and the second groove 2112 is an opening structure, so as to increase the radial hanging range of the transition wheel 11 or the attitude linking interface 21 between the first connecting portion 211 and the second connecting portion 111, and ensure that the first connecting portion 211 and the second connecting portion 111 can form a plug-in fit when a certain deviation exists in the hanging process, thereby realizing the hanging connection between the attitude linking interface 21 and the transition wheel 11.

Furthermore, the gap structure is U-shaped. I.e., either the first 2111 or second 2112 groove is a U-like shaped opening. Simple structure and easy realization.

Alternatively, as shown in fig. 4, a mounting groove 121 is provided on the plate body 12, and the transition wheel 11 is disposed in the mounting groove 121 and adapted to move in the axial direction of the transition wheel 11 and rotate around the axial direction of the transition wheel 11 in the mounting groove 121.

In this embodiment, the installation groove 121 is formed in the plate body 12, so that the transition wheel 11 is installed in the installation groove 121 and does not protrude from the outer surface of the plate body 12 or protrude by a small height. The transition wheel 11 is arranged in the mounting groove 121 and can rotate in the mounting groove 121 under the driving of the posture linkage interface 21, and meanwhile, the transition wheel 11 can also move in the mounting groove 121 along the axial direction of the transition wheel 11. Therefore, when the groove structure on the attitude linkage interface 21 and the convex structure on the transition wheel 11 generate a certain deviation due to multiple hitching, the groove structure and the convex structure are not at the same position and can not be hitched, at the moment, the attitude linkage interface 21 pushes the transition wheel 11 to move towards the groove bottom of the mounting groove 121 along the axial direction of the transition wheel 11, namely, the attitude linkage interface 21 jacks up the transition wheel 11 for a small distance to buffer the impact which is brought to the transition wheel 11 by the attitude linkage interface 21, the transition wheel 11 is prevented from being damaged due to the impact, and the service life of the transition wheel 11 is prolonged; then, the motor drives the attitude linkage interface 21 to rotate in a reciprocating manner within a small range, so that the groove structure and the protrusion structure are spliced, the groove structure on the attitude linkage interface 21 and the protrusion structure on the transition wheel 11 can still be automatically hooked after a certain deviation is generated due to manufacturing errors or long-time use, and the service life of the surgical robot instrument is prolonged.

In this embodiment, the plate body 12 of the adapter plate 1 is formed by assembling two plate structures, and the mounting groove 121 penetrates through the two plate structures. When the transition wheel 11 and the plate body 12 are assembled, one end of the transition wheel 11 is inserted into the mounting groove 121 of one plate structure, the other end of the transition wheel 11 extends into the mounting groove 121 of the other plate structure, and then the two plate structures are buckled, so that the transition wheel 11 is clamped between the two plate structures. In this embodiment, through setting up first anticreep boss 113 and second anticreep boss 123, and the external diameter of first anticreep boss 113 is greater than the internal diameter of second anticreep boss 123 to prevent to cross ferryboat 11 and drop from mounting groove 121, improved the fastness of crossing ferryboat 11 installation in mounting groove 121.

The embodiment of the invention also provides a surgical robot, which comprises the hanging mechanism of the surgical robot instrument.

The surgical robot comprises a man-machine interface, a driving mechanism and an instrument structure, wherein the instrument structure comprises an instrument body, an adapter plate 1 and an instrument base 2, the instrument body is installed on the instrument base 2, and the instrument base 2 and the adapter plate 1 are connected in a hanging mode through an attitude linkage interface 21 arranged on the instrument base 2 and a transition wheel 11 arranged on the adapter plate 1. The surgical robot in this embodiment has the same advantages as the hooking mechanism of the surgical robot instrument described above with respect to the prior art, and details are not described here.

The embodiment of the invention also provides a method for hooking the surgical robot instrument, which is based on the hooking mechanism of the surgical robot instrument and comprises the following steps:

The zero position of the posture linkage interface 21 refers to a position where the posture linkage interface 21 is installed on the apparatus base 2 according to design requirements, and is also an initial position (as shown in fig. 1) when the posture linkage interface 21 starts to rotate. In this embodiment, before the instrument base 2 is hooked to the adapter plate 1, the first connection portion 211 and the second connection portion 111 are hooked in the same direction. Like this, behind four first fillet portions 22 of apparatus base 2 and the four second fillet portions 124 one-to-one of keysets 1, only need to correspond first connecting portion 211 and second connecting portion 111, then do reciprocal rotation back at less within range through motor drive gesture linkage interface 21, just can make first connecting portion 211 and second connecting portion 111 form the cooperation of pegging graft, thereby realize the automation between apparatus base 2 and the keysets 1 and articulate, not only simple easy-to-use, and accuracy and efficiency when having improved and articulating.
