Knife edge polishing and grinding device provided with arc-shaped scalpel

Abstract

The invention relates to a knife edge polishing and grinding device provided with an arc-shaped scalpel. The knife edge polishing and grinding device comprises a base, a polishing and grinding fixture and a polishing and grinding head mechanism; the polishing and grinding fixture comprises a knife clamping base and a rail base plate, an arc-shaped rail and a matching body are arranged between the knife clamping base and the rail base plate, and a swing mechanism is formed by the knife clamping base and the rail base plate by matching of the arc-shaped rail and the matching body; when external force is acted on the knife clamping base, the knife clamping base swings on the rail base plate along the arc-shaped rail. A prismatic pair is arranged between the polishing and grinding fixture and the base or between the polishing and grinding head mechanism and the base, so that relative motion is generated between the polishing and grinding fixture and the polishing and grinding head mechanism; the polishing and grinding head mechanism comprises a first polishing and grinding wheel and a second polishing and grinding wheel, and the first polishing and grinding wheel and the second polishing and grinding wheel are arranged in a staggered mode in the direction of the relative motion of the polishing and grinding fixture and the polishing and grinding head mechanism. According to the knife edge polishing and grinding device, the structure is simple, the conception is ingenious, the cost is low, and the work efficiency is high. By means of the simple structure, effective space avoidance is achieved, therefore double-faced polishing and grinding can be carried out on a scalpel blade, and the processing efficiency of the knife edge polishing and grinding device is improved in multiples.

Description

technical field [0001] The invention belongs to production equipment for surgical blades, in particular to a polishing device for a surgical knife edge, in particular to a polishing device suitable for a circular arc surgical knife edge. The scalpel blade polishing device refers to a blade polishing device, a blade grinding device or a blade grinding and polishing device. Corresponding to the blade polishing device, the polishing wheel is the polishing wheel (the polishing wheel can be a nylon wheel, a cloth wheel, a wool wheel or a leather wheel, etc.), and corresponding to the blade grinding device, the polishing wheel is a grinding wheel (the grinding wheel can be a resin grinding wheel, Ceramic grinding wheel, etc.), corresponding to the blade grinding and polishing device, the polishing wheel must have both a grinding wheel and a polishing wheel. Background technique [0002] The production of surgical blades in China has a history of more than 50 years. Among them, th...

Problems solved by technology

[0003] However, due to the complex processing of the blade with the arc scalpel blade, there are the following disadvantages in manual polishing: first, manual polishing relies on manual operation experience, and the polishing of the blade must be done by skilled operators. The effect of polishing by novice operators may not be ideal, and...
