Description

TECHNICAL FIELD

[0001] The utility model relates to a cervical vertebra single door operation in cervical vertebra push plate door auxiliary forceps. BACKGROUND

[0002] The cervical vertebra posterior single door operation is a classical operation mode for treating diseases causing cervical spinal cord compression, such as cervical cone tube stenosis, cervical vertebra posterior longitudinal ligament ossification and the like. With the popularization and application of the ultrasonic bone knife in the cervical vertebra single door operation clock of hospitals across the country, in recent years, the cervical vertebra lamina opening side is mostly directly cut by using the ultrasonic bone knife, and the disconnection of the lamina can be completed in about 2 minutes by skilled doctors under the condition of smoothness, and the incision gap is about 2mm. SUMMARY

[0003] The utility model discloses a cervical vertebra single door operation in cervical vertebra push plate door auxiliary forceps, which is used for solving the problem of poor control of the force of the existing lamina opening tool.

[0004] In order to solve the above problems, the technical scheme of the utility model is as follows:

[0005] A cervical vertebra single door operation in cervical vertebra push plate door auxiliary forceps, which is used for solving the problem of poor control of the force of the existing lamina opening tool.

[0006] The anti-skid lines are arranged on the circumferential surface of the finger dolly wheel.

[0007] The surface of the insert piece is an abrasive surface.

[0008] The utility model has the advantages of:

[0009] 1、During the opening process of the auxiliary forceps, the thumb and the middle finger exert force, and the index finger pushes the finger dolly wheel, so that the opening process becomes smooth, and the force and speed of the opening process can be infinitely variable, the opening process of the entire lamina is fine and stable, the force is controllable, and the cervical vertebra high-risk operation requirements are met.

[0010] 2. The surface of the insert piece is designed as a rough sand surface, which increases the local friction force, greatly reduces the probability of accidental sliding of the insert piece, and reduces the risk of spinal cord injury. BRIEF DESCRIPTION OF DRAWINGS

[0011] The utility model will be further described below in combination with the drawings:

[0012] Figure 1 It is a three-dimensional structure schematic diagram of the utility model.

[0013] In the figure: ring 1, screw rod 2, screw pipe 3, handle 4, clamp head 5, insert piece 6, finger wheel 7, insert pipe 8, anti-skid line 9. DETAILED DESCRIPTION

[0014] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0015] A cervical vertebra single-door opening door auxiliary clamp in cervical vertebra single-door opening door surgery, including two hinge handles 4, one end of handle 4 is equipped with ring 1, and the other end is equipped with clamp head 5, one end of clamp head 5 is fixedly connected with the insert piece 6 with a thickness less than 1mm, a through hole is arranged on handle 4, and insert pipe 8 is hingedly connected in the through hole of one of handle 4, screw pipe 3 is hingedly connected in the through hole of the other handle 4, one end of screw rod 2 is screwed in screw pipe 3 after passing through insert pipe 8, and finger wheel 7 is arranged in the middle of double-head screw rod 2.

[0016] Anti-skid line 9 is arranged on the circumferential surface of finger wheel 7. Anti-skid line 9 can avoid the slip when the finger wheels 7 are driven by fingers.

[0017] The surface of insert piece 6 is a sand surface. The sand surface increases the local friction force, greatly reduces the probability of accidental sliding of the insert piece 6, and reduces the risk of spinal cord injury.

[0018] When the utility model is used, the ultrasonic bone knife completes cutting thick, the right thumb and middle finger of the surgeon are sleeved into the ring 1 of the auxiliary clamp after surgery, the index finger is attached to the finger wheel 7, the insert piece 6 is inserted into the thin bone groove, in the process of continuous and slow force of the thumb and middle finger, the index finger increases the opening force by driving the finger wheel 7, and the rebound of the lamina and the closing door are avoided, the size of the acting force, the time and the insertion angle of the insert piece 6 are determined by the surgeon according to the situation. When the surgeon has no force, the opening device will not be compressed to cause the rebound of the lamina or the closing door due to the fixing effect of screw rod 2.

[0019] The content described in the embodiments of the specification is only a list of implementation forms of the utility model concept, and the protection scope of the utility model should not be regarded as limited to the specific forms stated in the embodiments, and the protection scope of the utility model also extends to equivalent technical means that can be thought of by those skilled in the art according to the utility model concept.
