Transurethral bladder suturing system

Abstract

The invention relates to a transurethral bladder suturing system, and belongs to the technical field of medical instruments. The transurethral bladder suturing system comprises a stitching instrument and a double-end needle, a mechanism for mounting a double-ended needle is arranged at the tail end of the stitching instrument; the stitching instrument comprises a fixer, a sight glass and a stitching needle holder; annular grooves are formed in the two ends of the double-end needle. Complex suturing actions are split into simple actions, and the problem that suturing cannot be conducted under a cystoscope is solved. The boundary of various operations under the cystoscope is widened, for example, tumor which needs to be cut out of the bladder part originally can be completed under the cystoscope, the bladder can be sutured, and the bladder is prevented from being communicated with the outside of the bladder. And various defects of open surgery are avoided while the operation is simple and convenient and minimally invasive.

Description

technical field [0001] The invention relates to a transurethral bladder suture system, which belongs to the technical field of medical devices. Background technique [0002] Bladder cancer is the most common malignant tumor of the urinary system, originating from bladder transitional epithelial cells. According to the depth of invasion, it can be divided into non-muscle-invasive bladder cancer (NMIBC, 75%-85%) and muscle-invasive bladder cancer (MIBC, 15%-25%). The surgical treatment of bladder cancer includes transurethral resection of bladder tumor (TURBt), open partial cystectomy and radical cystectomy, the former two are bladder-preserving operations. [0003] TURBt enters the bladder retrogradely through the urethra, performs tumor resection, and uses electrocoagulation to stop bleeding, which is a classic treatment for bladder cancer. TURBt is operated through a natural channel, and the entire surgical process is confined to the bladder, so it has the advantages of m...

AI Technical Summary

Problems solved by technology

However, since there is no endoscopic bladder suture instrument at present, the depth and range of TURBt resection are obviously limited.

Although open partial cystectomy can expand the scope and depth of resection (full thickness), it has risks such as large trauma, difficulty in finding small lesions in other parts during the operation, and potential implant metastasis, so it is not the mainstream clinical choice
