Embodiment Construction

[0037] The following is attached Figure 1-5 The application is described in further detail.

[0038] refer to figure 1 , the embodiment of the present application discloses a joint socket file, which includes a ball cage cutter body 1 , a connecting sleeve 2 and a connecting rod 3 . Wherein, the connecting sleeve 2 is arranged on one end of the cage cutter body 1, and the cage cutter body 1 and the connecting sleeve 2 can be integrally formed by precision casting; one end of the connecting rod 3 is plugged into the connecting sleeve 2, and the connecting rod 3 The other end is used to connect with an external drive device. Driven by the external driving device, the connecting rod 3 can drive the ball cage cutter body 1 to rotate through the connecting sleeve 2 to file the socket of the human joint, so that the shape of the socket can meet the surgical requirements of joint replacement.

[0039] refer to figure 2 The cage cutter body 1 comprises a hollow spherical body 11...

Abstract

The utility model relates to an articular fossa file, and belongs to the technical field of medical instruments. The articular fossa file comprises a ball cage cutter body and a connecting rod, wherein a connecting sleeve is integrally formed on the ball cage cutter body; and one end of the connecting rod can be inserted into the connecting sleeve, the other end of the connecting rod is used for being connected with an external driving device, and under the driving of the external driving device, the connecting rod can drive the ball cage cutter body to rotate for filing. The articular fossa file has the advantages of being easy and convenient to install, wide in application range and stable in transmission.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a joint socket file. Background technique [0002] The socket file is a surgical instrument used to assist in the processing of the socket part of the human joint. At present, the socket file is usually stamped into a hemispherical shape by titanium alloy steel plate, and a cross is welded on the inner surface of the socket file. During use, the socket file is connected to the connecting rod through the cross. When connecting, the spring on the connecting rod needs to be compressed before it can be clamped tightly with the cross. [0003] In view of the above-mentioned related technologies, the inventor believes that the installation process of the socket file and the connecting rod is too cumbersome, which will consume a lot of time, resulting in increased operation time. Contents of the invention [0004] In order to improve the cumbersome and time-consumi...
