Description

Controllable telescopic guiding sling puncture outfit

Technical Field

The utility model relates to the technical field of syringes, in particular to a controllable telescopic guide sling puncture outfit.

Background

Female Stress Urinary Incontinence (SUI) is a medical condition that is often associated with weakening of the pelvic floor muscles and/or connective tissue that support the urethra in its proper position, and simple physical activity (e.g., running or jumping, even coughing or sneezing) can produce involuntary leakage of urine because the urethra is not properly supported and does not remain fully occluded during such activity.

U.S. patent No.5,112, 344 describes a method and apparatus for treating female incontinence, a surgical instrument for applying a filamentary element into a body comprising a tubular shaft having a handle at one end and a flexible needle slidably received in the shaft and adapted to receive the filamentary element at one end.

A method of treating female incontinence includes wrapping a filamentary element between the vaginal wall and rectus abdominus sheath of the anterior abdominal wall, passing it through each side of the urethra, tightening the loop to tighten the vaginal wall and urethra into proper spatial relationship with the pubic bone, thereby forming scar tissue between the vaginal wall and anterior wall of the abdominal pubic symphysis, and removing the filamentary element.

U.S. patent No.5,899,909 discloses a surgical instrument that includes a handle having a handle at one end and a connecting means at the other end to receive two curved needle-like elements at a time, one end of which is connected to one of the meshes for fixation.

In practice, the mesh is first passed through the vagina on one side and the other side of the urethra, respectively, and then a foam ring is formed on the other side of the urethra, respectively, forming a loop around the urethra between the urethra and the vaginal wall, the mesh extending over the pubic bone and through the abdominal wall and being tightened, the ends of the mesh being cut at the abdominal wall, and the mesh being implanted in the body, during which two 5 mm needles are passed through the PROLENE mesh and through the abdomen, respectively, to form a tension-free support around the mid-urethra.

Another method of handling SUI in US7070556B2 is the sling procedure, in which a needle or other suture suturing device is first inserted over the pubic bone, the needle is guided behind the pubic bone, through the subpubic fascia surrounding the urethra, and out of the body through an incision in the anterior vaginal wall, at which time the suture is attached to the needle and pulled back up through the abdominal cavity, securing the suture to the rectus abdominis.

Techniques for preventing puncture of internal structures during this type of procedure include laparoscopic procedures, which involve making incisions in the abdomen and inserting a video scope to see the progress of the needle through the abdominal cavity, these additional incisions being not optimal for the patient.

Also, needles that pass through the abdomen are not used to capture mesh but rather sutures that are pre-attached to the mesh or harvested fascia, which typically range in diameter from about 0.090ins to about 0.120 inches, do not form a large passageway over the fascia, which is only wide enough to pass the suture, and thus, the suture does not have the elongated nature of a PROLENE mesh, cannot provide tension-free support for the TVT, nor is it optimal to attach the mesh directly to these needles, because it is difficult, if not impossible, to pull the mesh through the narrow passageway created by the needle.
