Problems solved by technology

However, since the lesser trochanter is located in the inner rear and is surrounded by important structures such as the femoral artery, vein, and femoral nerve, it is very difficult to anatomically reset and effectively fix it. Now, doctors usually use their hands to hold it down based on experience, and then drill it with an electric drill. hole, it is very easy to hurt the doctor's hand, and the punching is not necessarily accurate, which is the deficiency of the existing technology

Embodiment Construction

[0010] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

[0011] It can be seen from the accompanying drawings that the lesser trochanter fixer of this program includes two linear handles 1 connected by hinges 2, and the two linear handles 1 are all provided with arc covers 3, and the arc covers The openings of the cover 3 are all towards another arc cover, and the arc cover 3 is provided with a through hole 10, and a hollow sleeve 4 is installed on the through hole of an arc cover 3, and the straight line The end of the handle 1 away from the arc-shaped cover 3 is provided with a limit strip 5 . The limiting bar 5 is arc-shaped, and a plurality of limiting teeth 6 are arranged on the limiting bar 5 . The sleeve 4 and the through hole are fixed by threads. The end of the linear handle 1 away from the arc-shaped cover 3 is provided with a ...

Abstract

The invention provides a thighbone lesser trochanter fixator which comprises two linear type handles which are connected through a hinge, wherein the two linear handles are respectively provided with an arc-shaped cover, an opening of one arc-shaped cover faces the other arc-shaped cover, a through hole is formed in each arc-shaped cover, a sleeve is installed on the through hole of one arc-shaped cover, and one end of each linear handle, away from each arc-shaped cover, is provided with a limiting strip. The fixator can effectively fix the thighbone lesser trochanter, meanwhile can improve precision of punching of an electrical drill, and is beneficial for proceeding of an operation.

Description

technical field [0001] The invention relates to a clinical orthopedic surgical instrument, in particular to a lesser trochanter fixer. Background technique [0002] In the prior art, the known technology is that with the progress and development of society, clinical medicine has also made rapid progress, especially in orthopedics. Among them, intertrochanteric fractures are also called intertrochanteric fractures, which refer to the greater and lesser trochanters of the femur. Fractures between the parts are combined with fractures of the lesser trochanter or extensive fractures. Femoral lesser trochanter fractures or extensive fractures lead to a significant decline in the femur's ability to resist external loads and torsion. Therefore, in the treatment of intertrochanteric fractures, fixation of the lesser trochanter is a factor that cannot be ignored. However, since the lesser trochanter is located in the inner rear and is surrounded by important structures such as the ...
