DETAILED DESCRIPTION

[0022] The content of the present application can be more easily understood by reference to the following detailed description of preferred embodiments of the application and the included examples. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. In case of conflict, the present specification, including definitions, will control.

[0023] Example 1:

[0024] Provided is an endoscopic minimally invasive surgery holding nail tooth bone grasping forceps as shown in Figures 1-3 The first clamping jaw 1 and the second clamping jaw 2 are rotationally connected, the second clamping jaw 2 is fixedly installed at one end of the fixed rod 3, and the handle 4 is installed at the other end of the fixed rod 3. The handle 4 is used to control the rotation angle of the first clamping jaw 1 relative to the second clamping jaw 2.

[0025] The first clamping jaw 1 is arc-shaped, and the end of the first clamping jaw 1 is provided with a first sharp tooth 11. The first sharp tooth 11 is inclined and hooked towards the fixed rod 3.

[0026] The distance from the outer side of the second clamping jaw 2 to the central axis of the fixed rod 3 is greater than the diameter of the fixed rod 3. The second clamping jaw 2 is provided with a receiving groove 21 for accommodating the first clamping jaw 1, and the length of the first clamping jaw 1 is less than the length of the second clamping jaw 2. The end of the second clamping jaw 2 is provided with a second sharp tooth 22. The second clamping jaw 2 and the arc-shaped first clamping jaw 1 cooperate to extend the first sharp tooth 11 and the second sharp tooth 22 into the side of the crushed bone, facilitating the grasping of the crushed bone. The width of the first clamping jaw 1 is less than the width of the second clamping jaw 2, the receiving groove 21 can accommodate the first clamping jaw 1, reducing the space occupied when the first clamping jaw 1 and the second clamping jaw 2 are closed, facilitating the extension of the bone grasping forceps.

[0027] The end of the second clamping jaw 2 close to the fixed rod 3 is provided with a first pin shaft 23, and the first clamping jaw 1 is rotationally connected with the second clamping jaw 2 through the first pin shaft 23.

[0028] The first clamping jaw 1 is provided with a first hollow slot 12 near one end of the fixed rod 3, and the first hollow slot 12 is provided with a second pin shaft 13. The handle 4 comprises a first handle 41, a second handle 42 and a third pin shaft 43, the first handle 41 is rotatably connected with the second handle 42 through the third pin shaft 43, and the first handle 41 is detachably connected with the fixed rod 3. Among them, the first handle 41 and the fixed rod 3 are optionally connected through buckle clamping. The upper part of the second handle 42 is provided with a second hollow slot 44, and the second hollow slot 44 is provided with a fourth pin shaft 45. The inside of the fixed rod 3 is provided with a through channel 31, and the through channel 31 is provided with a connecting rod 5, one end of the connecting rod 5 is rotatably connected with the second pin shaft 13, and the other end of the connecting rod 5 is rotatably connected with the fourth pin shaft 45. By rotating the second handle 42, the connecting rod 5 is driven to move, thereby driving the first clamping jaw 1 to rotate relative to the second clamping jaw 2, and the broken bone is gripped.

[0029] Embodiment 2:

[0030] As shown in Figure 4 , the difference between embodiment 2 and embodiment 1 is that the length of the first clamping jaw 1 is the same as the length of the second clamping jaw 2, and the first tine tooth 11 and the second tine tooth 22 are crossed with each other. The length of the first clamping jaw 1 is the same as the length of the second clamping jaw 2, which increases the length of the first clamping jaw 1, and the width of the first clamping jaw 1 is the same as the width of the second clamping jaw 2, and the first tine tooth 11 and the second tine tooth 22 are crossed with each other, which improves the gripping range and the strength of the first clamping jaw 1, and also does not increase the occupied space.

[0031] Working principle: by rotating the second handle 42, the connecting rod 5 is driven to move, thereby driving the first clamping jaw 1 to rotate relative to the second clamping jaw 2, so that the first clamping jaw 1 and the second clamping jaw 2 are opened, the first tine tooth 11 and the second tine tooth 22 are inserted into the two sides of the broken bone, and the broken bone is clamped, realizing the gripping of the broken bone.

[0032] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features. And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
