Embodiment Construction

[0022] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0023] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an eight-speed intramedullary cavity file stroke protection directional percussion device includes a housing 10, and the front end and the rear end of the housing 10 are arc-shaped; The first through hole 21 of the clamping column and the limiting protrusion 11 for matching with the limiting groove of the intramedullary cavity file 20 .

[0024] The limiting protrusion 11 may be a horizontal block-shaped protrusion, or a vertical block-shaped protrusion, or a hemispherical protrusion.

[0025] According to different manufacturers and different types of intramedullary cavity files, different limit protrusions are determined. Therefore, the front end of the housing can be adapted to different pulp...

Abstract

The invention discloses an eight-speed variable interface medullary cavity file stroke protection directional percussion device, which includes a shell, the front end and the rear end of the shell are arc-shaped; Limiting protrusion; there is a clamping mechanism in the housing; there are two limiting blocks at the rear end of the housing, and there are V-shaped grooves on the limiting blocks. The two limiting blocks are distributed up and down, and the two V-shaped grooves face each other. Setting; the housing is provided with a second through hole; the second through hole is located between the two limit blocks; the housing is pierced with a clip; The state of the hole and the state that the striking link can be stuck in the second through hole. The invention can realize rapid adaptation and connection with different pulp cavity files, and can also realize the pulp cavity files to work in eight gears, which greatly improves the convenience of pulp cavity files in use; it can also avoid human tissue , to avoid the expansion of human body wounds, help to reduce the wounds of the human body, and reduce the suffering of patients.

Description

technical field [0001] The invention relates to orthopedic medical instruments, in particular to an eight-speed medullary cavity file stroke protection directional percussion device. Background technique [0002] Rasps are commonly used surgical instruments in orthopedic surgery. When using the intramedullary cavity file for surgery, it is usually necessary to use a clamping device to clamp the intramedullary cavity file so that the operation can proceed smoothly. [0003] Since different types of intramedullary canal files have different joints, when different intramedullary canal files are used for surgery, different clamping devices need to be replaced, which brings great inconvenience to the operation. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an eight-speed medullary cavity file stroke protection directional percussion device in order to overcome the above-mentioned defects in the prior art. [0005]...
