Puncture outfit

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a puncture outfit.

Background

Stress Urinary Incontinence (SUI) refers to involuntary leakage of urine from the urethral orifice when abdominal pressure increases, such as sneezing, coughing, laughing, or exercise; urodynamic examination is manifested by involuntary urine leakage with increased abdominal pressure without detrusor contraction when the bladder is inflated. The prevalence rate of SUI of Chinese adult women is as high as 18.9%, and the prevalence rate of SUI is the highest at 28.0% in the age range of 50-59 years. Currently, urinary incontinence is becoming regulated internationally. Surgery has a long-term, definitive efficacy for most SUI patients. However, the operation is traumatic to the patient and has the risks of difficult urination, urgent urination, organ injury and the like after the operation, so when the operation scheme is prepared, the patient should be informed of the selectable operation modes and the advantages and risks of each mode, the time required for the operation, the hospitalization time, and the treatment of possible complications and complications.

Tension-free urethral sling (tension-free urethral tape) is the main surgical method of the disease and is mainly completed in two ways of a retropubic path and a obturator path. The vaginal tension-free mid-urethra suspension band via the retropubic route is used for completing the placement of a sling from bottom to top and from top to bottom. Retropubic approach: NICE suggested as the first treatment for SUI (grade a evidence) and this procedure has become the first line of treatment for SUI. The cure rate of the patient with the disease at any time for 7-11 years is 80% -90%, and the cure rate of the mixed urinary incontinence mainly comprising SUI is about 80%. The major complication of surgery is bladder injury, which requires care that a cystoscopy must be performed before the sling procedure is completed. In addition, surgical complications include bleeding, dysuria, urinary retention, urinary infections, sling exposure and erosion. The occurrence of the complications is mostly related to the complexity of the puncture technology of the operation mode and the design defects of instruments, and the specific expression is that the puncture path water separation is needed in the puncture process to protect the important vascular nerves of the vaginal wall and the pelvic cavity, but the current puncture outfit generally does not have the water separation function, and an additional pull tube is needed to separate the water, so that the clinical effect of the operation is poor.
