Description

Urethra middle section suspends suspender in midair

Technical Field

The utility model discloses a suspender is suspended in midair in urethra middle section belongs to the medical instrument field.

Background

Stress Urinary Incontinence (SUI) is a common disease affecting the quality of life of women, and is manifested by involuntary urine leakage when the abdominal pressure rises, such as sneezing, coughing, laughing or exercise. The current clinical treatment should select a treatment scheme according to the urinary incontinence degree of a patient, and for moderate-to-severe urinary incontinence patients, operation treatment is needed, and mid-urethra suspension is one of the common operation modes in clinic.

The mid-urethral suspension can be divided into a retropubic mid-urethral suspension (TVT) and a transobturator mid-urethral suspension (TVT-O) according to the implantation position of the sling; in the retropubic mid-urethra suspension (TVT), the puncture needle is directed to the pelvic cavity via the back of the pubic bone, which may damage the intestinal tract, bladder and blood vessels, causing the intestinal tract and bladder to penetrate and bleed, and the injury of the intestinal tract and blood vessels is a serious complication that may cause death of the patient.

In order to reduce perforation of an intestinal canal and a bladder and complications of blood vessel injury caused by a retropubic puncture approach, a transobturator mid-section suspension (TVT-O) is popularized, and the possibility of damaging the intestinal canal and the bladder is greatly reduced while a therapeutic effect equivalent to that of the retropubic transurethral mid-section suspension is obtained; however, since the puncture channel of the conventional percutaneous obturator operation needs to pass through the obturator internus muscle, the obturator membrane, the obturator ectomuscle and the thigh adductor muscle group, the incidence of pain at the thigh root part of the patient after the operation can reach 9.5% at different degrees.

The single incision mid-urethral sling procedure, which no longer passes through the adductor muscle group of the thigh, still passes through the obturator internus muscle, the obturator membrane and the obturator externus muscle, has two drawbacks: 1. the fixing force and the fixing durability are obviously reduced compared with the full-length sling; 2. post-operative pain may still occur by irritation of the obturator neuromuscular due to post-operative sterile inflammation after crossing the obturator membrane; clinical studies have shown that there is a higher incidence of sling-holding strength decline with this procedure.

The patent of the utility model discloses an adopt single notched operation approach also, its advantage has three: 1. the urethra middle section suspension sling takes the advantages of the urethral middle section suspension operation through the obturator foramen into consideration, improves the operation path and avoids the possibility of damaging intestinal tracts, bladder or blood vessels; 2. the displacement rate is low, the fixing mode of other transobturator mid-section suspension braces is realized by the friction force between the brace material and the tissues, the displacement rate is 14.3 percent, and the fixing mode of the utility model is the fixing of the inferior pubic periosteum, which can bear about 5-6kg of fixing tension force, so the fixing is firmer than the other transobturator mid-section suspension braces; 3. the side reaction is less. This patent suspender is to obturator internus muscle, obturator membrane not damaged to avoid the stimulation to the obturator nerve, painful incidence obviously reduces, and obturator vascular injury is showing and is reducing. This patent sling further reduces pain and the surgical hemorrhage incidence.
