Abstract
A surgical instrument used for the implantation of a Pubovaginal Sling for treating female stress urinary incontinence comprising of a guide tube, a detachable tapered tube and a flexible shaft. These elements penetrates the body cavity, place the standard Pubovaginal Sling in the proper place and helps obtaining the proper tension of the Sling.
Claims26
An instrument which aids inserting a Pubovaginal Sling to correct stress urinary incontinence (SUI) in women, comprising
- a substantially rigid guide tube having opposite open ends which are distal and proximal relative to a person using the instrument, said guide tube having a stem portion and a distal end portion extending generally laterally with respect to the stem portion and with locking engagement means at the proximal end,
- a handle on the stem portion of the guide tube generally adjacent the proximal end of the guide tube,
- a stiff but flexible shaft inside the guide tube having a distal end part movable distally relative to the guide tube,
- a detachable tapered tube having open ends with the large proximal end partially inserted inside the distal end of the rigid guide tube with means to prevent the further penetration of the detachable tapered tube into the guide tube and with the smaller distal end of the detachable tapered tube with an opening with just enough clearance to allow the exiting of said flexible shaft,
- a suture thread holder with a penetrating tip is provided on the distal end part of the shaft extending through and beyond the open distal end of the detachable tapered tube,
- said flexible shaft with grasping means at the proximal end externally to the guide tube with locking engagement means for engaging with the guide tube's proximal end locking engagement means during the instrument insertion,
- said shaft being manually movable longitudinally relative to the guide tube when the guide tube locking means and the flexible shaft locking means are not engaged, to move the distal end part of the shaft from an retracted position in which the suture thread holder is adjacent to the open distal end of detachable tapered tube, to a extended position in which the suture thread holder is farther away from the distal end of the guide tube, the distal end portion of the guide tube and the detachable tapered tube being configured to guide the distal end part of the shaft in place and the suture thread holder thereon along a substantially straight path extending generally laterally at an angle of not less than about ninety degrees with respect to the stem portion of the guide tube with the bend close to the distal end of said guide tube forcing the side of said flexible shaft to develop a normal force against the internal wall of the detachable tapered tube as the stiff flexible shaft tends to go in a straight line, said normal force creates enough friction to keep said detachable tapered tube from separating from said guide tube.
