DESCRIPTION:
BRIEF SUMMARY
This invention relates to a surgical instrument for use in the treating of female incontinence and to a method of treating such incontinence.
In one form the invention resides in a surgical instrument for the application of a filamentary element into the body for the purpose of treating female incontinence, said instrument comprising a substantially rigid linear tubular shaft having a handle at one end and being curved towards its other end to form a curved portion, a flexible needle element slidably received in the shaft and adapted at one end to receive a filamentary element and having an enlarged portion at its other end, whereby when the needle element is fully received in the shaft the enlarged portion of the needle defines a non-incisive convergent surface at the other end of the shaft and the one end of the needle element is exposed at the one end of the shaft, the shaft being dimensioned and curved towards its other end whereby when in use and in position the curved portion extends from the anterior vaginal wall to the anterior surface of the abdomen past the pubis.
In another form the invention resides in a method of treating female incontinence comprising looping a filamentary element between the wall of the vagina and the rectus abdominis sheath in the anterior wall of the abdomen whereby it passes to each side of the urethra, tightening the loop to bring the vaginal wall and the urethra into the correct spatial relationship to the pubis allowing the development of scar tissue between the vaginal wall and the anterior wall of the abdomen pubic symphysis and removing the filamentary element.
The invention will be more fully understood in the light of the particular embodiment of the invention described below. The description is made with reference to the accompanying drawings of which:
FIG. 1 is a schematic sagital section illustrating the circumstance which the urethro vesical junction wall is in a state of prolapse;
FIGS. 2, 3 and 4 are sagital sections illustrating the stages entry of the embodiment into the body;
FIG. 5 is a side elevation of the embodiment;
FIG. 6 is a side elevation of the embodiment with the needle element removed;
FIG. 7 is an isometric view of an alternative form of the embodiment; and
FIG. 8 is an isometric view of the form of the embodiment of FIG. 7 with the needle removed.
The embodiment is directed to a surgical tool for the treatment of female incontinence whereby as a result of the deterioration of the tissue or ligaments interconnecting the pubis with the vaginal wall. Such a condition can level to a loss of control of emissions from the urethra. The embodiment relates to an apparatus whereby the vaginal wall and urethra can be brought into a proper spatial relation with the pubis in order to restore continence. The embodiment comprises a surgical tool two forms of which are shown at FIGS. 5 and 6 and 7 and 8 which comprise a tubular shaft 11 having a handle 12 at one end and curved at its other end to a configuration approximately corresponding to the general curvature of the pubis between the vaginal wall and the anterior surface of the abdomen. As shown at FIGS. 7 and 8 which are directed to an alternative form of the invention the handle 12 may comprise a central radial arm 12a which is in the plane of curvature of the shaft to provide a positioning guide. The handle further comprises a pair of opposed arms 12b equally angularly offset from the central radial arm 12a. The opposed arms 12b provide facility for applying some leverage which may be required in using the instrument. The tubular shaft accommodates a needle element 13 which is provided at one end with an eye 14 for receipt of a filamentary element (not shown). The other end of the needle element is formed with an enlarged conically shaped head portion 15 which is receivable at the other end of the shaft 11 to close the other end of the shaft and define a convergent substantially conical surface to facilitate penetration of the instrument through the body cavity.
In using the instrument and as shown
