Rotary cutting device applied to internal resection of skin tumors

Abstract

The invention relates to a rotary cutting device applied to internal resection of skin tumors, and belongs to the field of surgical instruments. The rotary cutting device comprises an extending section and a control section, wherein the extending section is a slender tube, a spiral stirring shaft is arranged in the slender tube, a channel is arranged in the center of the spiral stirring shaft, and a movable rod is arranged in the channel; a plurality of serrated knives capable of being opened and closed are arranged at the front end of the slender tube, a conical head is formed after the serrated knives are closed, and the movable rod can control opening and closing of the serrated knives; the control section is arranged at the rear end of the extending section, the control section comprises a driving device for driving the spiral stirring shaft, the movable rod extends to the control section, the control section further comprises a negative pressure channel arranged on one side of the rear end of the slender tube, and a temporary storage bin is arranged at the tail end of the negative pressure channel. After the serrated knives capable of being opened and closed enter through a minimally invasive opening, the serrated knives are opened, the opened serrated knives are used for resecting the internal tissue of the tumor, and the spiral stirring shaft can convey the resected tissue backwards, so that minimally invasive treatment of the internal part of the tumor is realized, the wound is small, and scars are not easy to remain.

Description

technical field [0001] The invention relates to a rotary cutting device used for internal resection of skin tumors, belonging to the field of surgical instruments. Background technique [0002] Skin tumors refer to tumors originating from superficial soft tissues such as the skin, skin appendages, and subcutaneous tissue. The common ones are lipomas and sebaceous adenomas. For scars, the current minimally invasive knife can only realize the internal resection of the subcutaneous tumor, and the resection efficiency is low, and it is difficult to collect the internally resected tissue. [0003] In view of the above-mentioned problems in the prior art, the present invention designs and manufactures a rotary cutting device for internal resection of skin tumors to overcome the above-mentioned defects. Contents of the invention [0004] For the problems existing in the prior art, the present invention provides a rotary cutting device applied to the internal excision of skin tum...
