Novel broken nail extractor used for bone surgery

Abstract

The invention discloses a novel broken nail extractor used for bone surgery. The novel broken nail extractor comprises a top board. The top of the top board is equipped with an open-source single-chipmicrocomputer. The bottom of the top board is provided with a positioning device and an adjusting mechanism. The bottom of the adjusting mechanism is equipped with an elevating mechanism. An extraction mechanism is arranged on the bottom of the elevating mechanism. An input end of the open-source single-chip microcomputer is connected with an output end of an externally-connected power supply. The positioning device is used for positioning the position of a broken nail. The positioning device is highly intelligent and capable of accurately positioning so that the working capability of the broken nail extractor is greatly improved. The adjusting mechanism can adjust the working position of the extraction mechanism and shows great flexibility and automation level. Therefore, convenience isoffered to work of medical staff. The extraction mechanism can extract the broken nail and shows great maneuverability. Therefore, the operation difficulty of medical staff is greatly decreased. The novel broken nail extractor saves time and labor.
