Technical Field

The invention relates to the technical field of medical instruments, in particular to an adjustable universal type craniocerebral ring bow.

Background

Cervical vertebra injuries can be caused by poor sitting posture, traffic accidents, building construction accidents and various motion accidents, and the cervical vertebra injuries are clinically manifested as local pain of cervical vertebra, limited movement, involvement of spinal cord and nerve injuries, movement of limbs, sensory dysfunction and harm to the safety of patients due to respiratory dysfunction of serious patients.

Currently, treatment methods include non-operative treatment and operative treatment, depending on the degree and stability of cervical spine injury. The non-operative treatment mainly adopts the modes of skull traction reduction, brace fixation and the like, and adopts the method of annular traction to achieve the neck braking fixation and maintain the cervical vertebra sequence and stability. The operation treatment is to select a proper time for operation after the skull traction reduction. Therefore, skull traction reduction is an important link in the treatment process of cervical vertebra injury.

The skull traction reduction commonly used equipment is a skull hoop bow. The current craniocerebral ring arch is generally of a ring structure, and a handle is attached to the main body of the ring structure. A plurality of through holes are formed in the circumferential direction of the annular main body, and screws can be placed into the through holes. When the craniocerebral ring bow is used, a hole is drilled in the skull of a patient under the anesthesia condition, the annular main body is clamped on the skull, the craniocerebral ring bow is fixed on the head of the patient by screwing a screw, and then the traction reduction of the cervical vertebra is realized by lifting a handle. When fixing the cranial loop bow, the screw is screwed into the skull to a different extent, due to the different circumference of the head of the patient. For a patient with a small head circumference, the screw is screwed into the skull for a long time, and the screw may touch nerves, blood vessels and the like inside the skull, so that secondary injury to the patient is caused. For patients with large head circumference, although the screw is screwed into the skull for a short length, the craniocerebral arch cannot be stably fixed, so that the craniocerebral arch falls off in the traction reduction process. Therefore, the application range of the existing skull ring bow is small, and the practicability is low.

Detailed Description

Referring to fig. 1-3, fig. 1-3 illustrate front, top, and left views, respectively, of an adjustable generic craniotomy arch provided by embodiments of the present application. As can be seen from the attached drawings 1-3, the adjusting universal type craniocerebral ring bow provided by the embodiment of the application comprises a plurality of segments of bow bodies 1 and a plurality of connecting pieces 2, and each segment of bow body 1 is movably connected end to end into a ring shape through the connecting pieces 2 to form a ring-shaped craniocerebral ring bow. The bow body 1 in the embodiment of the present application is an arc-shaped structure and is made of metal parts. The end parts of the two sections of bow bodies 1 are movably connected through the connecting piece 2, and the distance between the end parts of the two adjacent sections of bow bodies 1 is adjustable, so that the length of the end part of the bow body 1 extending into the connecting piece 2 is adjustable. Because bow 1 is the annular through connecting piece 2 end to end swing joint, and bow 1 stretches into the inside tip length of connecting piece 2 adjustable, therefore the girth of annular craniocerebral ring bow is adjustable, can be applicable to the patient of different head girth lengths and use.

The bow body 1 is movably connected into an annular craniocerebral ring bow through a connecting piece 2, and a handle 3 is arranged on the annular craniocerebral ring bow so as to be convenient for drawing the annular craniocerebral ring bow through the handle 3. In order to facilitate the uniform stress of the annular craniocerebral arch during traction restoration, the two ends of the handle 3 are symmetrically arranged on the annular craniocerebral arch. Since the number of the bow 1 and the connecting piece 2 is determined according to the length of the bow 1, after the annular craniocerebral bow is formed, two ends of the handle 3 may be simultaneously positioned on the connecting piece 2, or simultaneously positioned on the bow 1, or one end is positioned on the connecting piece 2 and the other end is positioned on the bow 1, which is determined according to the actual application.

Preferably, the number of the bow 1 and the number of the connecting pieces 2 are both provided with even numbers, and as shown in fig. 2, the bow 1 in four sections is movably connected into a ring shape through four connecting pieces 2. In order to facilitate arbitrary adjustment of the circumference of the circumferential craniocerebral arch, the handle 3 is provided on the connecting piece 2 in the embodiment of the present application.

The connecting piece 2 is a part for connecting the bow bodies 1 as long as the bow bodies 1 can be connected and the distance between two adjacent bow bodies 1 can be adjusted. The embodiment of the present application provides a specific structure of a connecting element 2, as shown in fig. 4, fig. 4 shows a schematic structural diagram of the connecting element 2 in the adjusting universal type craniocerebral arch provided by the embodiment of the present application, namely an enlarged structural diagram at a in fig. 2.

As shown in fig. 4, the connector 2 provided in the embodiment of the present application includes a hollow tube 201 and a screw 202, wherein the hollow tube 201 is an arc-shaped pipe with a hollow interior, and may be made of a metal material. When connecting the two segments of bow bodies 1, the connecting piece 2 extends the end parts of the two segments of bow bodies 1 into the hollow pipe 201 from the two ends of the hollow pipe 201 respectively. The length of the bow 1 extending into the hollow tube 201 is adjusted according to the length of the head circumference of the patient. After the length is determined, the hollow tube 201 and the bow 1 are screwed together by the screw 202, so that the bow 1 and the hollow tube 201 are movably fixed by the screw 202. In order to make the craniocerebral ring bow formed by connecting the hollow tube 201 with the bow body 1 have a ring-shaped structure, the hollow tube 201 and the bow body 1 have the same radian.

In the adjusting universal type craniocerebral ring arch provided by the embodiment of the application, at least one screw 202 is provided, and at least one screw 202 movably fixes a section of hollow tube 201 and bow body 1. If the number of screws 202 is 4, each segment of the bow 1 and the hollow tube 201 are fixed by 2 screws 202.

Further, the ends of two adjacent segments of bow 1 are overlapped inside the hollow pipe 201, and the screw 202 movably fixes the overlapped part of two adjacent segments of bow 1, as shown in fig. 4. The diameter of the end of the bow 1 is gradually reduced so that two sections of bow 1 can be placed in the same hollow pipe 201, and the ends of the two sections of bow 1 can be overlapped. When the ends of the two bow bodies 1 are overlapped inside the hollow tube 201, the hollow tube 201 and the two bow bodies 1 are fixed by the screw 202 at the same time, and at this time, the structural strength between the hollow tube 201 and the bow body 1 is large, and a craniocerebral bow with a stable structure can be formed. Further, a staple 4 is provided on the bow 1, and the staple 4 is located close to the connecting member 2. The staple stack 4 in the embodiment of the present application can stabilize the trajectory of the screw 202 into the skull and the direction of advancement of the screw 202. Preferably, staple 4 takes the form of a circular truncated cone of a staple.

The regulation general formula of providing of this application embodiment can realize the swing joint between the multistage bow 1 through a plurality of connecting pieces 2, and adjacent two sections bow 1 is adjustable at the inside tip distance of connecting piece 2, and then can adjust the girth of the cranium ring bow that bow 1 and connecting piece 2 formed to make the cranium ring bow can be applicable to different patients, enlarge the application scope of cranium ring bow, improve utilization ratio and the practicality of cranium ring bow.
