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 variable interface pulp cavity file stroke protection directional percussion device includes a housing 10, the front end and the rear end of the housing 10 are arc-shaped; the front end of the housing 10 is provided with a The first through hole 21 of the clamping column of the cavity file 20 and the limit protrusion 11 for matching with the limit groove of the 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 ...

Abstract

The invention discloses an eight-gear variable interface medullary cavity file stroke protection directional knocking device which comprises a shell, and an arc is formed between the front end and therear end of the shell; a first through hole and a limiting protrusion are arranged at the front end of the shell. A clamping mechanism is arranged in the shell; two limiting blocks are arranged at the rear end of the shell, V-shaped grooves are formed in the limiting blocks, the two limiting blocks are distributed up and down, and the two V-shaped grooves are oppositely formed; a second through hole is formed in the shell; the second through hole is located between the two limiting blocks. A clamping piece is arranged on the shell in a penetrating manner; the clamping piece has the state thatthe knocking connecting rod can be smoothly inserted into the second through hole and the state that the knocking connecting rod can be clamped in the second through hole. According to the invention,rapid adaptation and connection with different medullary cavity files can be realized, and the medullary cavity files can work at eight gears, so that the convenience in use of the medullary cavity files is greatly improved; human tissues can be avoided, expansion of human wounds is avoided, reduction of the wounds of the human body is facilitated, and pains of patients are reduced.

Description

technical field [0001] The invention relates to orthopedic medical instruments, in particular to an eight-speed variable interface 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 variable interface medullary cavity file stroke protection directional percussion device in order to overcome the above-mention...
