Skeleton polishing former

Abstract

The invention relates to a skeleton polishing former, which comprises a patella former main body and an electric drill, sawteeth are distributed on one side of the patella former main body, a fixing block is welded to the other side of the patella former main body, a clamping block is fixedly connected to the other end of the fixing block, a sliding block is connected to the outer surface of the clamping block in a sleeving mode, and the clamping block and the limiting mechanism are connected with each other, the limiting mechanism is located in the control block, the limiting mechanism and a first clamping groove are connected with each other, and the first clamping groove is formed in the outer surface of the fixing block. According to the skeleton polishing former, the sawteeth are arranged on the front face of the patella former body, the patella former body has the three diameters of 2 cm, 2.5 cm and 3 cm, the head can be conveniently replaced at any time, the grinding requirements of various operations can be conveniently met, the edge of the patella former body is in the edge-free design, bone scraps can be conveniently and automatically discharged out of gaps during grinding, and therefore, the grinding time is saved, and the operation efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of knee joint surgery, and is specifically a bone grinding type. Background technique [0002] At the knee joint operation, some tibial surface is uneven, especially the cartilage grinding to the pit, not smooth, during surgery needs to be flattened, usually mainly with electric saw blade, a little bit of grinding, but this The operation is more troublesome, it is not easy to be flattened, and the operation is time consuming, the operation is relatively long, but the existing bone grinding model is still the problem; [0003] 1. The specifications of the skeletal strobe model cannot meet a variety of grinding requirements, and the bone scrap needs to be cleaned, extending the grinding time, reducing grinding efficiency, and the storage and use of the skeleton grinding model is not convenient. There is a certain safety hazard; [0004] 2, the skeletal grinding model cannot be quickly docked with the electric drill, ...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a bone grinding former to solve the problem that the bone grinding former proposed in the above-mentioned background technology has a single specification, which cannot meet various grinding requirements, and bone scraps need to be cleaned during grinding, which prolongs the grinding time and reduces In addition, the storage and use of the bone grinding and forming device is not convenient enough, and there are certain safety hazards. At the same time, the bone grinding and forming device cannot be quickly and accurately docked with the electric drill. Grinding shaper for quick replacement, to solve the problems that affect the operation process
