8. A surgical instrument according to claim 6 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 6 wherein the anterior surface includes at least four tactile surfaces.
10. A surgical instrument according to claim 9 wherein the tactile surfaces comprise grooves.
11. A surgical instrument according to claim 1 wherein the handle includes polycarbonate.
12. A surgical instrument according to claim 1 wherein the major posterior surface has a plurality of tactile surfaces with axes substantially perpendicular to the longitudinal axis of the handle.
13. A surgical instrument according to claim 12 wherein the tactile surfaces comprise protrusions.
14. A surgical instrument according to claim 1 wherein the handle includes a flare at a proximal end portion, the major posterior surface includes a concave surface, and the major anterior surface includes a convex surface.
15. A surgical instrument according to claim 1 wherein at least two thirds of the exterior surfaces of the elongate rod includes a surface treatment for enhancing grasping of the rod.
16. A surgical instrument according to claim 1 wherein depth to width ratio of the handle is less than 1:2.
17. A surgical instrument for addressing pelvic disorders comprising:
a handle having a width, height and depth; and
an elongate, slender, metal, rod emerging from the handle, the rod having a proximal end portion permanently fixed to the handle, an axis, and a distal end portion having a substantially blunt distal tip, the elongate rod having a length along the axis between the distal tip of the rod and a point on the rod axis where the rod emerges from the handle; and wherein:
the handle has a major anterior surface having a width and height, a major posterior surface having a width and height, and minor side surfaces extending between the major anterior and posterior surfaces and each having a depth and height,
the width of the handle is in a direction that is substantially perpendicular to the axis of the rod,
the height of the handle is more than about forty percent of the length of the rod and less than about eighty percent of the length of the rod,
the depth of the handle is less than the height of the handle,
the handle has a longitudinal axis along its height,
the major anterior surface of the handle has an elongate channel extending across the width of the handle, the channel having an axis that extends substantially perpendicular to the longitudinal axis of the handle,
the handle has a proximal and distal end, with the rod emerging from the distal end of the handle,
a flare is at a proximal end portion of the handle, and
the major posterior surface has a substantially concave surface and the anterior surface has a substantially convex surface.
18. A surgical instrument according to claim 17 wherein the major posterior surface of the handle includes an elongate depression having an axis that extends substantially parallel to the longitudinal axis of the handle.
19. A surgical instrument for addressing pelvic disorders comprising:
a handle having a width, a depth, a height extending between handle proximal and distal ends, and a longitudinal axis along the handle height; and
