Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The components in the present case are sequentially connected by a person skilled in the art, and specific connection and operation sequence should be referred to the following working principle, and the detailed connection means thereof are known in the art, and the following working principle and process are mainly described.

Because the restriction that has the model between traditional nail ware and the bone nail, consequently the department need prepare a large amount of nail ware of getting, satisfies the nail operation of getting of different grade type, different model bone nails, and adopts pliers to operate, often because the pliers opening is great, leads to not good with the fixed effect between the bone nail, influences and gets the nail operation.

In view of the above, the utility model provides the bone surgery nail extractor, which realizes fixation aiming at fixation of different types and specifications through the cooperation among the clamping jaw, the limit square rod, the vertical rod, the spring, the supporting rod and the slope, is convenient for pulling, rotating and other actions, does not need to prepare different nail extractors according to different bone nails, is more diversified in matched bone nails, and meanwhile, the clamping jaw transversely moves, has inconvenient angle, is more stable than the clamping of pliers on the bone nails, and is convenient for a user to operate.

1-4, the orthopedic surgery nail extractor comprises a shell 1, wherein a clamping unit is arranged in the shell 1; the clamping unit comprises a limit square rod 2, a clamping jaw 3, a spring 4, a vertical rod 5, a supporting rod 6, a roller 7 and a slope 8; the both ends of spacing square pole 2 respectively with the inner wall bottom both sides fixed connection of shell 1, the equal swing joint of outer wall both sides of spacing square pole 2 has clamping jaw 3, spring 4 has been cup jointed to the outer wall of spacing square pole 2, the both ends of spring 4 offset tightly with two clamping jaw 3 respectively, the top of spacing square pole 2 is provided with montant 5, the equal fixedly connected with branch 6 in the bottom both sides of montant 5, the end rotation of branch 6 is connected with gyro wheel 7, the outer wall of gyro wheel 7 is laminated mutually through domatic 8 and one side that clamping jaw 3 is close to shell 1.

In the specific implementation process, it is worth particularly pointing out that the shell 1 is used for holding the use by a user, the limit square rod 2 can limit the clamping jaw 3, the clamping jaw 3 can move transversely, the distance between the two clamping jaws can be adjusted, but the clamping jaw cannot rotate and move vertically, the side face of the clamping jaw 3 is provided with the slope 8, the purpose of the device is that when the vertical rod 5 drives the supporting rod 6 to move downwards, the slope 8 can be pressed by the roller 7, so that the two clamping jaws 3 are close to each other, and when the vertical rod 5 moves upwards, the two clamping jaws 3 are far away from each other under the action of the spring 4, the inner sides of the clamping jaws 3 are processed into different shapes, the clamping jaws can be fixedly matched with different types, and the specific shapes can be processed according to actual requirements, so that the device is not limited.

Specifically, when using this bone surgery nail extractor, the user holds shell 1, place two clamping jaw 3 respectively in the bone nail both sides of waiting to take off, select clamping jaw 3 suitable position to carry out the clamp according to the shape of bone nail, drive montant 5 downstream, montant 5 drives branch 6 downstream, can oppress domatic 8 through gyro wheel 7, make two clamping jaw 3 be close to each other like this, thereby clamp the bone nail, can carry out actions such as pulling, changeing, so can be applicable to the bone nail of different specifications and shape, and for traditional nail forceps of getting, can not influence the clamping strength of bone nail because of the angle of opening and shutting, it is more stable.

In one embodiment, an adjusting nut 9 is screwed above the outer wall of the vertical rod 5, and the bottom of the outer wall of the adjusting nut 9 is rotatably connected with the housing 1 through a bearing.

In the specific implementation process, it is worth particularly pointing out that the adjusting nut 9 is connected with the vertical rod 5 through threads, so that the adjusting nut 9 can be rotated to drive the vertical rod 5 to move upwards or downwards, fixation is achieved, a user does not need to press the vertical rod 5 manually at any time, and the bone screw can be rotated conveniently.

Further, the outer wall of the adjusting nut 9 is provided with anti-slip patterns 10.

In particular, it is worth mentioning that the design of the anti-slip threads 10 is aimed at increasing the friction of the outer wall of the adjusting nut 9, so that slipping is avoided.

Further, a limit handle 11 is fixedly connected above one side of the outer wall of the shell 1.

In the specific implementation process, it is worth particularly pointing out that the limiting handle 11 is arranged, so that the case 1 is prevented from being out of hand in the process of holding the case 1 by a user and pulling out the bone nails.
