Example Embodiment

[0015] Specific embodiments: The minimally invasive overall resection of breast lesions is guided by high-frequency color Doppler ultrasound, and the entire cutting process is performed under real-time ultrasound monitoring to ensure that the lesions can be completely removed. First, insert the sleeve into the body through the guide post guide through a minimally invasive hole of about 2-5 mm, close to the lesion, such as Image 6 Shown. Pull out the guide post, insert the pawl knife, and screw it into the sleeve through the thread, such as Figure 7 Shown. When the pawl cutter head is flush with the sleeve, rotate the sleeve outward to retreat, allowing the cutter head to gradually emerge. At this time, rotate the pawl knife left and right, and start to cut the tissue. When the eight pawl knives are fully opened, stop the sleeve from retreating, and quickly rotate the pawl knives left and right to perform an overall peeling of the lesion. The pawl knives and sleeves are push...

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...
