Description

Automatic deburring device for scalpel

Technical Field

The utility model relates to the field of surgical instruments, concretely relates to automatic burring device of scalpel.

Background

The ophthalmic scalpel is small in size and high in requirement on machining precision. Currently, most of ophthalmic scalpels on the market are produced by grinding, and the grinding can cause burrs on the cutting edge of the scalpel in different degrees, so that the deburring treatment needs to be carried out on the cutting edge of the scalpel. The deburring mode in the prior art mainly includes two kinds: one is manual deburring, in which a worker adjusts the position of the cutting edge of the scalpel relative to the polishing wheel and brings the cutting edge of the scalpel into contact with the polishing wheel for polishing. However, the deburring mode has low efficiency and high requirement on workers, and the result of excessive grinding of the cutting edge of the scalpel is easy to occur during polishing, so that the processing precision is low. The other is chemical deburring, which removes burrs on the cutting edge of the scalpel by chemical etching. However, the deburring mode can only remove burrs with small size, and cannot process burrs with large size, so that the application range is small. Therefore, an automatic deburring device is needed, which can improve the deburring efficiency, ensure the processing precision of the scalpel and has a wide application range.
