Breast tumor cutting device

Abstract

The invention discloses a breast tumor cutting device. The breast tumor cutting device comprises an operating rod, a drilling assembly, an outer cylinder, a cutting assembly, a deformation driving assembly and a cutter body driving assembly, wherein the operating rod is a hollow rod; the drilling assembly comprises a drill rod and a drill bit, and the drill bit is arranged on the drill rod; the outer cylinder can slidably sleeve an exposed end, and the head and the tail of the outer cylinder are connected with the outer wall of the operating rod to form an accommodating cavity; the cutting assembly comprises a mounting net and a cutter, the mounting net is arranged at an inserting end, and comprises a plurality of elastic mounting strips, one end of each mounting strip is connected to theinserting end, the other end of each mounting strip is a free end, the free ends are inserted into the accommodating cavity, and the cutter can move back and forth along the mounting strips; the deformation driving assembly is arranged in the accommodating cavity and connected with the mounting strips, and can drive the mounting net to expand or contract; and the cutter body driving assembly is arranged on the mounting strips, and can drive a cutter body to move back and forth along the mounting strips. The breast tumor cutting device can quickly cut a tumor, so that the operation time is shortened.

Description

technical field [0001] The invention relates to a breast tumor cutting device. Background technique [0002] Breast tumor is a common disease that plagues women. In breast tumor resection, because patients strive to cure the disease, due to aesthetic and psychological effects, pursuers breast tumor resection develops in the direction of small trauma and high efficacy. For this reason, Minimally invasive tumor resection surgery is widely used. When performing minimally invasive tumor resection, due to the large volume of some tumors and the small operation port on the body surface, it is necessary to divide the internal tumor into small pieces that can be removed from the external incision in order to remove the tumor smoothly. However, the existing tumor The cutting device is not only complex in structure, but also requires repeated cutting, resulting in longer cutting operation time, which will inevitably bring inconvenience to the operation.
