Abstract

The invention discloses a medullary cavity file handle. The medullary cavity file handle comprises a pedestal, a handgrip and a plate spring, wherein the pedestal comprises a front-segment matrix and a rear-segment matrix, and the front-segment matrix is provided with an operation cavity; the operation cavity is arranged to penetrate the front end surface of the front-segment matrix, and a medullary cavity file insertion groove is formed on the front end surface; the operation cavity is internally fixedly provided with a first shaft rod and a second shaft rod; one end of the handgrip is installed in the operation cavity and is in pivoted connection with the first shaft rod, the other end of the handgrip extends out of the operation cavity, and a third shaft rod is fixedly arranged on the handgrip; the plate spring is simultaneously in pivoted connection with the second shaft rod and the third shaft rod; and a locking structure is formed at the front end of the plate spring. According to the invention, the plate spring is drawn through the handgrip, the locking structure on the plate spring realizes fastening on a file, locking and separation are quite convenient, besides, the pedestal, the handgrip and the plate spring are conveniently split for disinfection and packaging, and the operation safety is improved.

Description

technical field [0001] The invention relates to a handle of a pulp cavity file. Background technique [0002] Total hip replacement surgery mainly includes the implantation of the acetabular side prosthesis and the implantation of the femoral stem prosthesis. The main instruments used for the implantation of the femoral stem prosthesis include the medullary canal rasp and the medullary canal rasp handle. At present, the designs of the handles of pulp cavity files used by various manufacturers are different, and the internal locking mechanisms are different. Most of the pulp cavity file handles in the prior art use a four-bar mechanism, and some of the pulp cavity file handles in the prior art use a cam mechanism. These instruments in the prior art cannot be conveniently disassembled, cannot be sterilized and packaged conveniently, and are relatively cumbersome to maintain. In addition, the operating directions of these existing instruments are not suitable for adjustment, ...
