Surgical instruments
View Patent ↗A novel surgical instrument is shown and described. The surgical instrument is useful in pelvic floor repair procedures such as sling procedures for treating incontinence. Also, a novel, ornamental design for a handle for a surgical instrument is shown and described.
1. A surgical instrument for addressing pelvic disorders comprising:
a handle having a width, height and depth, and said handle further having a proximal and distal end, and a longitudinal axis along its height, and
an elongate, slender, metal, curved rod emerging from the distal end of the handle, the rod having a proximal end portion permanently fixed to the handle, a curved axis, and a distal end portion having a distal tip, the elongate curved rod having at least a portion with a radius and a length along the curved axis between the distal tip of the rod and a point on the rod axis where the rod emerges from the handle, the length being between about 6 inches and about 12 inches;
the handle having a major anterior surface having a width and height, the major anterior surface being situated to face a surgeon with the rod extending generally toward the surgeon, a major posterior surface having a width and height, at least two minor side surfaces having a depth and height, the width of the handle being in a direction that is substantially perpendicular to the axis of the rod, the handle having a height more than forty percent of the length of the rod and less than eighty percent of the length of the rod, and the depth of the handle being less than the height of the handle,
said major anterior surface of the handle including an elongate channel extending across the width of the handle with an axis that extends substantially perpendicular to the longitudinal axis of the handle, and
said major anterior surface further including a plurality of tactile surfaces distal to the elongate channel, said plurality of tactile surfaces extending in a direction substantially perpendicular to the longitudinal axis of the handle.
2. A surgical instrument according to claim 1 wherein the rod is curved along a substantial portion of its axis with a radius of curvature that is between 4.5 and 5.5 inches, and the distal tip is substantially blunt.
3. A surgical instrument according to claim 1 wherein the length of the channel along the longitudinal axis of the handle is more than 0.5 inches and less than 1 inch.
4. A surgical instrument according to claim 1 wherein the rod comprises stainless steel and at least one material comprising the handle is a polymer with a density less than the stainless steel density.
5. A surgical instrument according to claim 1 , wherein the height to width ratio is greater than 3:1.
6. A surgical instrument according to claim 1 wherein the handle includes a flare at a proximal end portion, the posterior surface including a concave surface and the anterior surface including a convex surface.
7. A surgical instrument according to claim 1 wherein at least two thirds of the exterior surface of the elongate rod includes a surface treatment for enhancing grasping of the rod.
8. A surgical instrument according to claim 1 wherein the posterior surface has a plurality of tactile surfaces extending in a direction substantially perpendicular to the longitudinal axis of the handle.
9. A surgical instrument according to claim 1 wherein the handle includes polycarbonate.
10. A surgical instrument according to claim 1 wherein the tactile surfaces comprise protrusions.
11. A surgical instrument according to claim 1 wherein the anterior surface includes at least four tactile surfaces.
12. A surgical instrument according to claim 11 wherein the tactile surfaces comprise grooves.
13. A surgical instrument according to claim 1 wherein depth to width ratio of the handle is less than 1:2.
