Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of medical devices, in particular to a kind of orthopedics reduction forceps. BACKGROUND
[0002] During the operation of small tubular fracture such as fibula and clavicle, surgical reduction is needed, however, there are many inconveniences in the current reduction forceps, the existing special reduction forceps generally have larger mouth or fixed angle, which cannot be flexibly applied during operation. In order to improve the above situation, various instruments are currently used in clinical application, but there are still many disadvantages:
[0003] 1. When using tissue forceps for reduction, the elasticity is large, the bone tissue is not fully clamped, and the instrument is easily damaged;
[0004] 2. When using straight forceps for reduction, the opening of the straight forceps is limited, the clamping of bone tissue is also limited, and the reduction force is not enough;
[0005] 3. The bone rongeur may crush the bone during reduction. SUMMARY
[0006] In view of the above defects of the prior art, the present application provides an orthopedic reduction forceps, which comprises two single-blade forceps fixed by a fixing bolt, each single-blade forcep is composed of a forcep head 1, a forcep body and a forcep handle from the beginning to the end, the thickness of the forcep head 1 of each single-blade forcep is greater than 4mm, and the blade thickness is greater than 1mm, a plurality of reduction teeth 11 are arranged at the clamping opening of each forcep head 1, and a sharp tooth 12 is arranged at the top end of the forcep head 1.
[0007] Preferably, the reduction teeth 11 of the two single-blade forceps are arranged in a staggered manner.
[0008] Preferably, the opposite clamping surfaces of the two sharp teeth 12 are provided with arc-shaped blade edges.
[0009] Preferably, a non-return fixing rod 13 is arranged at the forcep handle of the two single-blade forceps, and the non-return is prevented by meshing.
[0010] Preferably, a holding handle for assisting force application is further arranged at the tail end of the forcep handle.
[0011] Preferably, the single-blade forcep is made of metal material.
[0012] Advantages of the present application:
[0013] 1. The sharp tooth can be easily inserted between the fracture blocks, tightly fitted with the fracture blocks, and stably grasped the fracture blocks, and the reduction teeth can fix the fracture ends, so as to ensure that the fracture ends maintain good alignment relationship, and some small tubular bones can also be clamped;
[0014] 2, the force arm of the forceps body is short and thick, which can better hold the fracture end, reduce the inconvenience caused by the small operation space, and compared with the long and thin and unstable holding of the curved forceps and the tissue forceps, the fracture end is difficult to effectively reset.

[0019] In order to make the person skilled in the art better understand the technical solutions of the present application, and make the above-mentioned features, objects and advantages of the present application more clear and easy to understand, the present application will be further described below in combination with examples. The examples are only used to illustrate the present application and not to limit the scope of the present application.
[0020] As Figs. 1-2 can be seen, the present application comprises: two single-blade forceps fixed by a fixed bolt, each single-blade forceps is composed of a forceps head 1, a forceps body and a forceps handle from the beginning to the end, the thickness of the forceps head 1 of a single single-blade forceps is greater than 4mm, the blade thickness is greater than 1mm, a plurality of reset teeth 11 are arranged at the clamping opening of each forceps head 1, and a sharp tooth 12 is arranged at the top end of the forceps head 1. The single-blade forceps as a whole adopts a metal material.
[0021] In the present embodiment, the shape and structure of the sharp tooth 12 of the reset forceps can better adapt to the reset demand of the comminuted fracture block. The sharp form of the sharp tooth makes it easy to insert between the fracture blocks and tightly fit with the fracture blocks. The important feature of the sharp tooth is the greater holding force. It can firmly grasp the fracture block, and it is not easy to make the fracture block slip during the operation, which provides a powerful guarantee for accurate reset.
[0022] The reset tooth 11 of the reset forceps aims to avoid the sliding of the fracture end when holding the fracture end. A plurality of reset teeth can fix the fracture end from multiple directions and angles, ensuring that the fracture end maintains a good alignment relationship. Whether it is a separation reset or a rotation reset of the fracture end, a plurality of reset teeth can play a great role, helping doctors to more accurately adjust the position of the fracture end.
[0023] In the conventional surgery, two orthopedic reduction forceps can be used in cooperation, the tip teeth 12 and the reduction teeth 11 of the reduction forceps are obliquely clamped to the fracture ends, and then the fracture ends are pulled, pressed and reset by rotating the reduction forceps or / and the two reduction forceps in cooperation; the fracture ends are fixed by the handle of the closed forceps and the forceps head 1 of the reduction forceps to complete the temporary reduction.
[0024] In the above steps, in order to avoid the reduction teeth 11 from falling off, the reduction teeth 11 of the two single-blade forceps are arranged in a staggered manner.
[0025] In order to expand the practicability, especially for resetting some tubular bones, the opposite clamping surfaces of the two tip teeth 12 are provided with arc-shaped blades, the tubular bones are mostly flat round structures, and have a little sliding property on the surface, especially the tubular bones with small diameters such as clavicle, ulna and radius, and fibula, the arc-shaped blades can be clamped more closely, and are not easy to be broken.
[0026] In order to prevent the reduction forceps from falling off during the temporary fixation, and also to save the strength of the doctors, the handle of the two single-blade forceps is provided with a non-return fixing rod 13, the non-return fixing rod 13 is provided with small non-return teeth, the non-return teeth are engaged to prevent the non-return, that is, after clamping, the non-return fixing rod 13 is self-locked to complete the temporary clamping and fixation.
[0027] Since the weight of some bones is large, the tail end of the handle is also provided with a holding handle for assisting the force, so as to facilitate the continuity of the force.
[0028] The above embodiments only exemplarily illustrate the principles and effects of the patent application, and are not used to limit the patent application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the patent application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the patent application should be covered by the claims of the patent application.
