Abstract

The invention belongs to the technical field of medical instruments and discloses a multipoint biopsy sampling device for a breast tumor minimally invasive surgery. A sleeve is connected with a push rod in a sleeving manner, the upper end of the push rod is welded with a push handle, and a second spring is clamped between the push handle and the sleeve; a piston is clamped on the push rod, the lower end of the piston is connected with a connecting rod, the connecting rod is connected with a hook head through screws, and hanging thorns are welded at the hook head; the lower end of the sleeve passes through the through hole and a cutter, the end of the cutter is welded with a press plate, and a first spring is fixed between the press plate and the sleeve; a groove is formed in the left sideof the sleeve and corresponds to the position of the cutter; a fixing band is clamped on the press plate, and antiskid lines are formed in the press plate; the end of the sleeve is connected with a blocking cover through a rotating shaft, an arched groove is formed in the blocking cover, and a poke rod is arranged at the left end of the arched groove; and an expansion pad is bonded to the arched groove. The multipoint biopsy sampling device can cut lesion tissue quickly and prevent cut lesion tissue from falling off.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a multi-point biopsy sampling device used for minimally invasive surgery on breast tumors. Background technique [0002] At present, the earliest minimally invasive surgery in the treatment of breast fibroids is the Mammotome Vacuum Assisted Breast Minimally Invasive Rotary Excision System developed by Johnson & Johnson. The developed automatic mammary gland rotary cutting system. They are mainly composed of two devices: a rotary cutter and a vacuum pump, which can repeatedly cut suspicious breast lesions to obtain breast histological specimens, providing more and better methods for breast cancer detection and diagnosis, and at the same time It also provides a technical basis for minimally invasive resection of benign tumors. Compared with traditional surgery, minimally invasive surgery has the advantages of small wound, less pain, faster recovery, shorter hospital stay...
