Problems solved by technology

In addition, this kind of rotary cutting motion has higher requirements on the sharpness of the cutting edge of the acetabular reamer. When the cutting edge is worn to a certain extent, the acetabular reamer cannot continue to be used, which makes the life of the acetabular reamer relatively limited.

Embodiment Construction

[0023] Preferred embodiments according to the present invention will be described in detail below with reference to the accompanying drawings and examples. In a preferred embodiment of the present invention, the present invention is described by taking an acetabular reamer for artificial hip joint as an example. However, those skilled in the art should understand that these exemplary embodiments are not meant to form any limitation to the present invention, for example, the mortar file of the present invention can be used in other artificial joint replacement operations with joint sockets such as shoulder joints . In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.

[0024] figure 1 is a perspective view of an acetabular reamer for hip replacement surgery according to an embodiment of the present invention. Such as figure 1 As shown, the acetabular rasp 1 includes a base 10 and a...

Abstract

The invention provides an acetabular file for joint replacement operations. The acetabular file comprises a base and a main body, wherein the base comprises at least one first channel for being connected with a high-pressure liquid supply device and at least one second channel for being connected with a negative pressure recovery device; the main body comprises at least one first hole and at leastone second hole; the base and the main body are connected with each other or form an integrated body to make the first channels communicated with the first holes and make the second channels communicated with the second holes. In addition, the invention further provides an acetabular file assembly with the acetabular file. The acetabular file is simple in structure and low in manufacturing requirement, and liquid circulation is utilized to achieve a self-cooling process. In addition, the acetabular file has no mechanical wear so that the service life can be prolonged.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a mortar file used for joint replacement surgery. Background technique [0002] In the current joint replacement surgery, it is usually necessary to remove the cartilage or part of the bone tissue of the socket with an acetabular file to expand the socket, and then press an artificial prosthesis such as an acetabular cup into the polished socket. For example, hip replacement surgery is typical of such procedures. Traditionally, the acetabular reamer is a hemispherical thin metal layer with a base of a cross support frame, and its outer surface is provided with cutting edges, for example, crescent-shaped cutting edges. When the acetabular reamer is used to grind the hip joint socket, the cutting edge on the acetabular file contacts the inner surface of the acetabular socket of the hip joint, and the socket is ground in the hip joint socket through the rotational friction moveme...
