Internally fixed suspender assembly for urinary tract middle-section suspension surgery

Abstract

The invention discloses an internal fixation sling assembly for mid-urinary tract suspension, which is composed of a guide, a flexible probe and an adjustable sling device. The guide is composed of an anchor clip, a handle, and an anchor clip control rod. and an arc-shaped elbow, the adjustable sling device is composed of a lower urethral flat piece, a tubular mesh, an anchor bolt, a movable sling lock and an adjustable sling handle. Compared with the prior art, the present invention reduces bladder, Risks such as blood vessel and nerve damage are further simplified and the operation time is shortened. And the end of the sling has its own anchor bolt to firmly lock the sling to the obturator fascia, reducing the risk of loosening and displacement of the sling; and the length of the sling can be adjusted, which can be applied to patients with various pelvic types. The treatment of stress urinary incontinence by using the device is effective and has the value of popularization and practicality.

Description

technical field [0001] The invention relates to a medical device, in particular to an internally fixed mid-urinary tract suspending belt assembly. Background technique [0002] The International Continence Society defines stress incontinence as the involuntary loss of urine when straining, coughing, or sneezing. An estimated 35% of adult women worldwide suffer from stress urinary incontinence. Treatment for stress urinary incontinence includes conservative, medication, and surgery, with severe stress incontinence requiring surgery.

Problems solved by technology

However, the current TVT-O puncture system is mostly a three-incision sling system, and the sling needs to pass through the obturator hole from the root of the thigh, which may cause leg pain and some neurological symptoms in the obturator area, and once bleeding occurs in the obturator puncture area difficult to handle

Recently, some single-incision slings have appeared on the market, which can pass through the obturator membrane and be fixed by the tension of the tissue itself, without passing through the thigh root, which reduces some risks. Satisfied, consider that the heel sling cannot be fixed on the obturator membrane and is not firm, resulting in loose sling
