Operational puncture instrument and method for treating stress urinary incontinence

Abstract

The invention discloses an operational puncture instrument and a method for treating stress urinary incontinence. The instrument is hollow, and consists of a handle, a body part, a head end and a tail end; and the part, entering the body of a patient, of the instrument has certain curvature, and the curvature is matched with anatomical curvature of the human body from a puncture starting point to a puncture ending point. The tail end of the instrument is connected with fluid and pressure produced by the fluid so as to introduce the fluid and the pressure to an opening part of the head end; during operation, the puncture instrument punctures an obturator membrane and a muscle tissue, and reaches the lower side of the vagina mucosa; and by external pressure, a fluid supporting force formed at the head end can separate the gaps of surrounding normal tissues, so the instrument can move forward in the absence of resistance and with smaller tissue damage. Under the guide of the index finger, inside the vagina and outside the vagina mucosa, of an operation doctor, the puncture instrument moves to a middle incision of the front wall of the vagina and is connected with one end of a suspender; and the puncture instrument quits along the original puncture path and implants the suspender into the body on the rear wall of the middle section of the urethra so as to treat the stress urinary incontinence. The parts of the instrument are various; and the connection between the fluid and the instrument can be designed as required.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments and methods, and in particular relates to a surgical puncture instrument and an operation method for treating stress urinary incontinence. Background technique [0002] Due to factors such as childbirth and age, middle-aged and elderly women will undergo pathological changes in the supporting tissue of the pelvic floor, and some of them will have symptoms of urinary incontinence, especially stress urinary incontinence. When the patient's abdominal pressure increases during walking, laughing, and work, the bladder neck and urethra move down excessively, causing urine to flow out involuntarily, which seriously affects the quality of life. A recent survey on the incidence of urinary incontinence in Beijing simply found that 23%-45% of the female population had varying degrees of urinary incontinence, about 7% had obvious symptoms of urinary incontinence, and about 50% of them were stress...

Problems solved by technology

However, for doctors with little surgical experience, if the anatomical layer of the vaginal submucosal layer is not clear, it will cause great damage to the patient; improper operation may also damage the obturator vascular nerve plexus, causing serious complications

In addition, in the existing outside-in method, after the puncture instrument passes through the obturator, the index finger of the doctor's other hand needs to enter the vaginal mucosa through the incision on the anterior vaginal wall to guide the puncture instrument from the inside of the obturator. Excessive separation of the underlying layer to accommodate the fingers, causing excessive damage and bleeding
