Abstract

The invention discloses an orthopaedic medical device and more particularly discloses a medullary cavity filing and extracting device used for a minimally invasive surgery of an artificial hip joint in a femur side. The medullary cavity filing and extracting device comprises a main body and a handle slidingly arranged on the main body, wherein one end of the handle is provided with a connector; the handle is connected with a latch hook through the connector; one end of the main body is provided with a base; and the main body is also provided with a fixing block. The medullary cavity filing and extracting device provided by the invention combines both the filing and the extracting of the medullary cavity as a whole, the filing is realized by pressing the handle and knocking the base and the extracting is realized by extracting the main body. The medullary cavity filing and extracting device is convenient to use and strong in filing and extracting force.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to a medullary cavity rasp and puller used for minimally invasive surgery on the femoral side of an artificial hip joint. Background technique [0002] Before and during the minimally invasive surgery on the femoral side of the artificial hip joint, clinicians urgently need systematic guidance materials that suit the national conditions, especially tools for driving or pulling out the medullary canal rasp. Various reasons, such as factory location, caused many problems in the process of entering or pulling out the pulp cavity file, such as muscle damage and enlarged incision during the removal process, causing secondary injuries to the patient. The invention of the intramedullary cavity file puller is based on what the clinician obtained in the operation practice in order to solve the above-mentioned problems. Contents of the invention [0003] The technical p...
