Magnetic repulsion and attraction reciprocating medical mute saw

Abstract

The invention relates to the technical field of medical treatment, and discloses a magnetic repulsion and attraction reciprocating medical mute saw. The magnetic repulsion and attraction reciprocatingmedical mute saw comprises an equipment body, a supporting frame is arranged in the equipment body, a driving power source is arranged in the equipment body, a driving gear is movably connected to the outer side of the driving power source, and magnetic attraction clamping teeth are meshed with the outer side of the driving gear; a rotating magnet is fixedly installed on the outer side of the magnetic attraction clamping tooth, a monopole magnet is movably installed in the equipment body and located on the outer side of the rotating magnet, a connecting rod is fixedly connected to the outer side of the monopole magnet, a connecting spring is movably connected to the end, away from the monopole magnet, of the connecting rod, and a bearing block is movably connected to the outer side of theconnecting spring. According to the magnetic repulsion and attraction reciprocating medical mute saw disclosed by the invention, impact force generated when the cutting saw cuts can be buffered by arranging a buffer spring, the damage to the cutting saw due to large rigid impact during cutting is avoided, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a reciprocating medical mute saw with magnetic repulsion and mutual attraction. Background technique [0002] Existing medical reciprocating saws are used for bone sawing in orthopedic surgery. Their structures mainly include screw transmission mechanism, cam transmission mechanism, rack and pinion transmission mechanism, and crank slider transmission mechanism. The tool guide mechanism mainly includes inclined plane locking mechanism and Eccentric locking mechanism. Take the fork reciprocating saw that is widely used as an example, because it uses a mechanical structure to drive its work, it will inevitably produce a lot of noise when it moves, and the doctor needs to ensure absolute silence during the operation to avoid distraction. These noises will make the doctor's operation very boring, resulting in low work efficiency and danger. These reciprocating mechanisms are relati...

Problems solved by technology

Take the fork reciprocating saw that is widely used as an example, because it uses a mechanical structure to drive its work, it will inevitably generate a lot of noise when it moves. The doctor needs to ensure absolute silence during the operation to avoid distraction. These noises will make the doctor's operation very boring, resulting in low work efficiency and danger. These reciprocating motion mechanisms are relatively simple, the guidance is not very accurate, the scope of use is small, the structure is complicated, and the efficiency is not high. Therefore, we propose a magnetic Reciprocating medical silent saw that repels and attracts each other
