Cutting device for hand bone butt joint operation

Abstract

The invention discloses a cutting device for hand bone butt joint surgery, which comprises a first metal frame, a second metal frame, a third metal frame and a fourth metal frame, the first metal frame and the second metal frame are combined, the third metal frame and the fourth metal frame are combined, and an upper layer slideway is arranged on the inner side of the first metal frame. According to the cutting device for the hand bone butt joint operation, the finger positioning mechanism, the tool bit driving mechanism and the movable cutting mechanism are arranged, fingers needing to be cut can be conveniently and rapidly positioned and clamped during the operation, the working stability performance is improved, the cutting effect is smoother, and the cutting efficiency is improved. The position of the tool bit can be conveniently driven, the grinding effect is achieved while cutting is conducted, the flatness is improved, cutting operation can be conducted more rapidly, cutting is conducted through vertical translation of the positioning metal frame, the operation is simple and rapid, the deviation situation is avoided, observation can be conducted better, and the effect is better.

Description

technical field [0001] The invention relates to the medical field, in particular to a cutting device for hand-bone butt joint surgery. Background technique [0002] The cutting device for hand-bone docking surgery is a support device for finger cutting and docking. In the case of bone cracks or fractures in the fingers, hand-bone docking surgery is required. First, cut off the broken part of the finger, and then perform the fracture positioning and docking. , With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of cutting devices for hand-bone butt surgery. [0003] The existing cutting devices for hand-bone joint surgery have certain drawbacks in use. After several fingers are broken, the joint length varies. Some use forceps to cut the excess bone, which is time-consuming and laborious, and the bone incision is not flat. If the bones are not cut and polished, sometimes the butt fingers will gro...

AI Technical Summary

Problems solved by technology

[0003] The existing cutting device for hand bone butt joint operation has certain disadvantages in use. After a few fingers are broken, the length of butt joint is different. Some use pliers to cut redundant bones, which is time-consuming and laborious. If the bones are not cut and polished, sometimes the butt fingers will become crooked, which is not conducive to people's use. In addition, it is not easy to quickly and conveniently position and engage the fingers during the amputation operation, and there may be shadows during work. It is not easy to observe the situation, which has brought some adverse effects to people's use process. Therefore, we propose a cutting device for hand bone butt joint surgery.
