Femoral hip joint stem holder

Abstract

The invention relates to a femoral hip joint stem holder. The holder comprises a threaded rod, a screwing end cap, a handle and a movable handle, wherein the head of the threaded rod is provided with threads which are matched with a femoral stem; the screwing end cap is connected with the tail end of the threaded rod; the handle is rotatably sleeved at the periphery of the rear part of the threaded rod; and the movable handle is vertically fixed on the handle. The femoral hip joint stem holder can be used conveniently and fast, is rational in torque transfer and has a broad operating range, so that the success rate of surgery is improved.

Description

technical field [0001] The invention relates to a medical device, in particular to a hip joint femoral handle holder (B-B handle holder) for driving a prosthesis into a patient's body. Background technique [0002] see figure 1 As shown, the existing hip joint femoral handle holder is made up of chuck 11, chuck female 12, connecting rod 13, end cap 14 and handle 15, wherein, chuck 11, chuck female 12, end cap 14 And live handle 15 is all fixed on the connecting rod 13. When implanting the femoral prosthesis in the hip joint, put the prosthesis into the groove of the clamp head 11 first, align the head of the connecting rod 13 with the groove of the femoral handle, and slide the clamp head 11 to adjust the gap between it and the clamp head female 12. position, to adapt to different femoral stems, keep the connecting rod 13 coaxial with the center of the prosthesis, rotate the handle 15, drive the connecting rod 13, and hold the femoral stem firmly. After the prosthesis is ...

AI Technical Summary

Problems solved by technology

[0003] Although the above-mentioned hip joint femoral stem holder can indeed be used as an auxiliary device to hold the prosthesis and drive it into the patient's body, it is indeed progressive, but it is found that there are still some shortcomings in its structure during actual use. In actual application, the femoral stem holder of the hip joint failed to achieve the best use effect, and its shortcomings can be summarized as follows:

[0004] 1. The chuck head 11 is relatively large, which will affect the doctor's field of vision during the operation;

[0005] 2. It is inconvenient to hold the prosthesis. It is not only necessary to align the head of the connecting rod 13 with the femoral stem groove, but also to adjust the relative relationship between the clip 11 and the clip female 12. The adjustment process is cumbersome and takes a long time

[0006] 3. When inserting the prosthesis, it is easy to damage the femoral stem with the taper

[0007] This shows that the above-mentioned existing hip joint femoral stem holder obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently
