Medullary cavity file machining tool and medullary cavity file semi-finished product

Abstract

The invention provides a medullary cavity file machining tool and a medullary cavity file semi-finished product, and belongs to the technical field of tool clamps. The medullary cavity file machining tool comprises a fixing assembly, a positioning assembly and a locking assembly, the fixing assembly comprises a fixing chassis, a medullary cavity file semi-finished product is placed on the side, away from a machining lathe, of the fixing chassis, and the near end and the far end of the medullary cavity file semi-finished product are located on the outer side of the fixing chassis; the positioning assembly comprises a positioning block and a positioning screw, the positioning block is fixed to the fixing base plate through the positioning screw, and a receding space used for containing a medullary cavity file semi-finished product is formed in one side of the positioning block. The locking assembly comprises a locking plate and a locking screw, and the locking plate is fixed to the side, away from the machining lathe, of the medullary cavity file semi-finished product through the locking screw. According to the medullary cavity file machining tool and the medullary cavity file semi-finished product, the medullary cavity file semi-finished product can be effectively fixed, the near end and the far end of the medullary cavity file semi-finished product can be conveniently machined, and the medullary cavity file machining tool is simple in structure and easy to popularize.

Description

Technical field [0001] The present invention belongs to the field of tooling fixture technology, specifically relates to a kind of medullary filing processing tooling and medullary cavity file semi-finished products. Background [0002] Medullary filing is a common medical device in artificial hip replacement surgery, in the artificial hip replacement surgery, before implanting the femoral stalk prosthesis into the femoral bone marrow cavity, it is necessary to use the medullary filing to shape the medullary cavity, the medullary filing as the key surgical instrument in the artificial hip replacement surgery, the demand is huge, and the product accuracy requirements are getting higher and higher, in the processing process, generally in the proximal end of the medullary cavity file to set the clamping block, the clamping block is fixed on the workbench, for subsequent processing operations, After the middle and proximal processing of the medullar file, it is necessary to remove t...
