Device for minimally invasive excision of breast nodules

Abstract

The device comprises an outer sleeve, an inner sleeve and an expansion device arranged between the outer sleeve and the inner sleeve, the expansion device comprises a plurality of elastic umbrella ribs arranged in the outer sleeve, the lower ends of the elastic umbrella ribs are fixedly connected with a fixing ring, the fixing ring is provided with a control sliding block, and the control sliding block is connected with the outer sleeve. The control sliding block is embedded into the sliding groove of the outer sleeve, the fixing ring is driven by the control sliding block to move in the axial direction of the outer sleeve, and when the end of the expansion device moves to the outside of the outer sleeve, the end of the expansion device is unfolded and forms a horn-shaped structure to be used for expanding a cavity close to a breast nodule, and a cavity gap space for minimally invasive resection surgery is manufactured. The nodule can be conveniently operated and cut by using a minimally invasive instrument, so that the breast nodule and the breast minimal nodule lesion can be accurately and completely cut, the problems of easy nodule mass residue, postoperative hematoma and the like in the minimally invasive surgery in the prior art are solved, and the early diagnosis and treatment level of the breast benign and malignant nodules is improved; the method is of great significance to diagnosis and treatment of breast nodules.

Description

technical field [0001] The invention relates to the field of medical minimally invasive technology, in particular to a minimally invasive resection device for breast nodules. Background technique [0002] Breast nodules are common breast diseases, usually can be divided into benign nodules and malignant nodules, the incidence rate is increasing year by year, accounting for about 60% of all breast diseases, seriously affecting the physical and mental health of women. Ultrasound, mammography, or magnetic resonance MR examinations are routine imaging examination methods for discovering breast nodules, masses, or clustered calcifications. The risk assessment for judging benign and malignant nodules is represented by BI-RADS classification. At present, the treatment methods of breast nodules include conservative treatment, conventional surgical excision and minimally invasive surgical excision. Surgical resection is the most effective treatment. Traditional conventional surgery...

Problems solved by technology

[0004] The purpose of the present invention is to design a minimally invasive breast nodule resection device, which can accurately and completely remove breast nodules and small lesions, and solve the problems of residual nodules and lumps that are prone to occur in minimally invasive surgery in the prior art, so as to improve the efficiency of benign and malignant breast nodules. The level of early diagnosis and treatment of breast nodules is of great significance to the diagnosis and treatment of breast nodules
