Abstract
There is disclosed a surgical instrument for inserting material into the body. The surgical instrument generally includes an outer tubular member. The instrument has a longitudinal section and an arcuate section having at least two different radii of curvature. An inner member is movably positioned within the outer tubular member and includes structure for engaging a length of material to draw the material through the outer tubular member and into the body. Methods of using the surgical instrument to position a length of tape beneath the urethra to form a support are also disclosed.
Claims23
A surgical instrument comprising:
- a first member having a longitudinal section defining a longitudinal axis;
- and
- an arcuate section extending distally from the longitudinal section, the arcuate section having a proximal portion, a central portion, and a distal portion, the proximal portion of the arcuate section curves away from the longitudinal axis in a first direction and defines a first radius of curvature, the central portion of the arcuate section curves towards the longitudinal axis in a second direction and defines a second radius of curvature, and the distal portion of the arcuate section curves toward the longitudinal axis in a third direction and defines a third radius of curvature, wherein each radius of curvature is different from the other two radii of curvature.
A method of positioning a length of material in a body comprising the steps of:
- (a) providing a surgical instrument comprising:
- a first member having a longitudinal section defining a longitudinal axis, the first member including a hollow outer tube member;
- a stylet at least partially movable within the outer tubular member and engageable with the length of material;
- and
- an arcuate section extending distally from the longitudinal section, the arcuate section having at least a first portion and a second portion, the first portion and the second portion having different radii of curvature;
- (b) making first and second incisions in the body;
- (c) inserting the instrument into the second incision;
- (d) passing the instrument through an object in the body, and advancing the instrument around the body in a substantially arcuate path towards the first incision such that least a portion of the instrument is accessible therethrough;
- (e) engaging the material with the stylet;
- and
- (f) withdrawing the instrument from the body.
