Description
Technical Field
The invention belongs to the technical field of surgical instruments and methods, and particularly relates to a device for adjusting and fixing tension of a surgical mesh and surgical application thereof.
Background
Female urinary incontinence is a common illness in women, with prevalence approaching 50% currently being statistically global, about half of which is stress urinary incontinence (Stress Urinary Incontinence, SUI). Stress incontinence refers to urinary incontinence in which urine does not overflow autonomously from the external urethral orifice in the absence of bladder detrusor contraction when the bladder pressure is greater than the maximum urethral pressure, and often occurs when the abdominal pressure suddenly increases, for example: laughing, sneezing, coughing, etc. Postmenopausal populations are more prone to morbidity. Most of the pathogenesis is that the birth injury is caused during the delivery, the estrogen level is reduced after menopause, the pelvic floor soft tissue is relaxed, and the like. SUI was initially recognized as one of five major diseases affecting human health in the mid 90 s, known as "social cancer". Particularly in China, SUI is more and more valued with further aging of population. A recent investigation of the incidence of urinary incontinence in Beijing alone has found that 23% -45% of women have varying degrees of urinary incontinence, about 7% have significant urinary incontinence symptoms, and about 50% are stress urinary incontinence. A group abroad reported 37.7% of women with urinary incontinence over 60 years old. For this reason, effective methods for treating SUI are sought, which are of urgent and significant clinical significance.
In order to treat urinary incontinence, techniques for inserting an elastic insert into the interior of the vagina or injecting hydrogel (polymer) particles into soft tissues around the urethra or ureter are described in various documents such as U.S. patent publication No. 6808485, japanese laid-open patent publication No. JP1998-155897, korean laid-open patent publication No. KR2003-34218, etc. Tension-free transvaginal mid-urethral suspension (TVT, tension-free vaginal tape) is the gold standard for SUI treatment in surgical treatment. The TVT is considered to have the advantages of high cure rate, simple and convenient operation, small wound, quick postoperative recovery, less complications, low recurrence rate and the like at present, and is widely applied clinically.
There have been various methods for the treatment of stress incontinence historically, with the efficacy of surgical treatment being the most desirable and urethral or bladder neck sling procedures being the most effective method of surgical treatment. With advances in technology and in-depth understanding of the principles of urinary incontinence generation in recent years, a variety of minimally invasive approaches have been employed to achieve optimal therapeutic results by employing surgical procedures and techniques that minimize patient damage. One current treatment for stress incontinence is tension-free suspension of the mid-section of the transvaginal urethra, i.e., an incision of about 2cm is made in the anterior vaginal wall, and a sling to be placed at the bottom of the mid-section of the urethra is placed into the soft tissue space in the body by a puncturing device to enhance the supporting action of the pelvic floor soft tissue on the urethra. Thus, when the abdominal pressure increases, the amplitude of the downward movement of the urethra is limited by the implanted sling, and the ureter is pressed and closed, so that the urine leakage of the patient is controlled.
The two ends of the implanted sling can generally run in the body through two ways, after the skin is led out, the external part of the sling is sheared off, and the internal part plays an anchoring role on the sling along with the growth of surrounding soft tissues. One is the retropubic approach, where the piercing instrument brings the ends of the sling along the back of the pubis from the abdominal wall, which has the potential to damage the bladder or other soft tissue behind the pubis, such as the vascular plexus, leading to serious complications. The other is a transobturator approach, a puncture instrument passes through obturator foramens, and two ends of a sling are pulled along the vaginal submucosa towards the obturator foramens of pelvis at two sides, and are led out of the body from the skin at the inner side of thigh. The operation adopting the latter way is called a transobturator mid-urethra suspension operation, and is a method which is more commonly adopted at present because of the fact that the main blood vessels are far away from the bladder and the pelvis, complications are rare, the operation is simple, and popularization is facilitated.
There are two ways to pass the obturator instrument through the obturator canal in the mid-urethral suspension. From the anterior vaginal wall incision to the skin on the inner thigh (inside-out) and from the outer thigh through the obturator foramen to the anterior vaginal wall incision, and back out (outside-in) after connection with the sling. Both of these procedures require blunt or sharp separation of the vaginal submucosa from the vaginal incision to the obturator foramen with surgical scissors to facilitate passage of the penetrating device and placement of the sling. The vaginal submucosa is normally loose tissue and the surgical bleeding is very small when the separation layer is correct.
In recent years, a single incision transvaginal tensionless mid-urethral suspension (SIS) has been developed and practiced to reduce the trauma area. The hanging strips with two ends connected with the obturator anchors are adopted, two sides of the obturator anchors are positioned on the corresponding obturator membranes in sequence, the tension and the position of the hanging strips are moderately adjusted, the operation can be completed, the operation time is greatly reduced, and the wound healing speed is higher. In the existing operation process, because the incision breadth is limited, on the basis that the difficulty of implanting and positioning the obturator anchor in the obturator membrane is overcome, the adjustment and positioning and locking of the sling tension become very painful steps for a relevant doctor to perform the operation, and the required instruments are complex in operation. Namely, the tension of the sling is inconvenient to adjust under the condition of poor visual conditions, and the tension change amplitude caused by positioning and locking is large when the tension of the sling is adjusted properly, so that the sling is not suitable for doctors to efficiently and reliably complete the operation.
