Embodiment Construction

[0008] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0009] Such as figure 1 , as shown in 2 and 3, the main body (1) is circular, which is convenient for clamping to the chuck, the femoral stem (8) is installed in the groove (4), and the spacer (3) and the fixing block (2) pass through the main body (1) The upper threaded hole (5) is connected and fixed with the upper hole of the fixing block (2) and the counterbore (7) by bolts. The groove (4) can limit the rotation and movement of the femoral stem (8), so as to achieve the effect of firm fixation. The counterweight hole (6) is a threaded hole, and screw counterweights of different sizes can be loaded as required, so that the center of the part coincides with the rotation center of the main body (2), ensuring firmness and reliability.

Abstract

The invention relates to the technical field of medical equipment machining, in particular to a femoral stem turning clamp. The clamp comprises a main body (1), a fixed block (2) and a cushion block (3). The main body (1) is provided with a groove (4), and the groove (4) fits the appearance of femoral stem; the end face of the main body (1) is provided with a threaded hole (5) and can be connected with the fixed block (2), and the middle cushion block (3) adjusts the height and performs auxiliary fixation. The fixed block (2) is provided with the groove (4), the groove (4) is matched with the groove of the main body (1) to make the femoral stem firmly fixed to the main body (1), and the circumference of the fixed block (2) is provided with a hole and a counterbore (7) so that the fixed block (2) can be fixed to the main body (1). The main body (1) is further provided with a counterweight hole (6), so the main body (1) is stable and reliable during machining, and machining quality is ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical processing of medical instruments, in particular to a jig for machining a femoral stem. [0002] technical background [0003] A fixture is a tool commonly used in production to clamp a workpiece so that other equipment can process the workpiece. For some special-shaped parts in medical device products, it is difficult to process and clamp, and the stability of batch processing is poor. Contents of the invention [0004] The purpose of the present invention is to provide a simple structure, convenient operation, firm and reliable femoral handle machining fixture. [0005] In order to achieve the above purpose, the technical solution adopted in the present invention is: a femoral stem turning fixture, including a main body (1), with a groove on the main body (1), and matching the groove on the fixing block (2), the femoral stem ( 8) Firmly fixed, add pads (3) to adjust the height, and adapt t...
