Rotary self-absorbing pawl-type knife system for minimally-invasive whole excision of breast lesion

Abstract

With the arrival of the medical minimally-invasive age, the requirements of women patients on minimal invasion and beauty is higher and higher, therefore, a breast-lesion minimally-invasive whole excision system which is new, can replace the current minimally-invasive therapy and can be commonly accepted by the women patients needs to be urgently designed. The invention relates to the field of minimally invasive surgical medicine, and provides a new surgical technology, and a minimal invasion method is adopted to realize whole excision of breast-lesion tissues by a rotary self-absorbing pawl-type knife of a special surgical knife and a matched instrument. A rotary self-absorbing pawl-type knife system for minimally-invasive whole excision of the breast lesion mainly comprises a pawl knife, a sleeve, a guide column, a guide wire, a vacuum suction pump and the like. The system has the characteristics that (1) the positioning is accurate; (2) the lesion is accurately excised; (3) the safety is ensured by a highly-scientific design; (4) the diagnosis is more accurate; (5) the infection rate is low and the more economical effect is achieved; (6) the surgery is fast and convenient; (7) the beauty effect is good, and effects of no pain in surgery and no scar after surgery are achieved; (8) the cost is low; (9) the surgical instrument is simple in structure, easy in operation and easy in popularization; and (10) the domestic and foreign blanks are filled, and the application prospect and the social-economic benefits are wide.

Description

technical field [0001] The present invention relates to the field of minimally invasive surgical medicine, and proposes a new surgical technology, which uses a minimally invasive technique to realize "overall resection" of breast lesion tissue through a special special-shaped scalpel rotating self-priming pawl-type cutter and its supporting equipment. Background technique [0002] With the advent of the era of minimally invasive medicine, female patients have higher and higher requirements for minimally invasive and cosmetic treatments. Therefore, it is urgent to design a new set of treatments that can replace the current minimally invasive therapy and can be generally accepted by female patients. The minimally invasive overall resection system for breast lesions. [0003] The indications of this system are: 1. A breast mass of about 1 cm found by B-ultrasound or mammography but difficult to touch by physical examination; 2. Atypical malignant calcifications found by mammogr...

Problems solved by technology

Mammotome rotary cutting system is a relatively advanced and popular minimally invasive method at present. It is a system specially developed by Johnson & Johnson for biopsy of breast lumps. Its application range has been expanded in China to be used for lump resection. , its disadvantages are as follows: 1. The tumor tissue cannot be removed as a whole in one operation, and the tumor tissue needs to be divided and removed many times, which destroys the integrity of the original tumor; 2. Equipment costs Too high (30--500,000 yuan / unit), high surgical cost (5,000-10,000 yuan / case); 3. Low penetration rate, few beneficiary groups
