Handle and surgical article
View Patent ↗Handles for needles suitable for pelvic floor surgical procedures are described.
1. A handle for a surgical instrument having a needle with a substantially straight portion and a curved portion, the handle comprising:
an elongate body having a proximal end region including a proximal end, a distal end region including a distal end, top and bottom portions that define a height, and side portions that define a width;
wherein the proximal end region includes a maximum width and a maximum height, and the distal end region includes a maximum width and a maximum height;
wherein the maximum width of the proximal end region is greater than the maximum height of the proximal end region and the maximum width of the distal end region is greater than the maximum width of the proximal end region;
wherein the straight portion of the needle is adapted to project from the distal end of the body; and
wherein at least the top portion has a surface that is sized and shaped to receive a user's thumb in the distal end region.
2. A handle according to claim 1 wherein the proximal end region has generally convex surfaces.
3. A handle according to claim 1 wherein the top and bottom portions have substantially flat surfaces in the distal end region.
4. A handle according to claim 1 wherein the maximum height of the proximal end region is greater than the maximum height of the distal end region.
5. A handle according to claim 1 wherein the side portions have a plurality of grasping ribs.
6. A handle according to claim 1 wherein the distal end region has fins.
7. A handle according to claim 1 wherein the handle is constructed from a polymeric material.
8. A handle according to claim 1 wherein the elongate body has an elongate axis, and the straight portion of the needle has an elongate axis, and the axis of the elongate body is parallel to the axis of the straight portion of the needle.
9. A handle according to claim 1 wherein the elongate body has an elongate axis, and the straight portion of the needle has an elongate axis, and the elongate axis of the elongate body is coaxial with the elongate axis of the straight portion of the needle.
10. A surgical instrument for treating pelvic floor disorders comprising:
a metallic needle portion having a substantially straight portion and a substantially curved portion;
a handle portion constructed at least in part from a polymeric material, the handle portion comprising a proximal end region, a distal end region, and a transition region between the proximal and distal end regions, each region having a width;
wherein the transition region is reduced in width relative to the proximal and distal end regions; and
wherein the proximal end region has a maximum height that is greater than a maximum height of the transition region and a maximum height of the distal end region.
11. A surgical instrument according to claim 10 wherein the metallic needle portion has a tip portion that is at least substantially blunt, and the curved portion is substantially helical.
12. A surgical instrument according to claim 10 wherein the metallic needle portion is constructed from stainless steel.
13. A surgical instrument according to claim 10 wherein the transition region has a maximum width that is less than a maximum width of the distal end region and a maximum width of the proximal end region.
14. A surgical instrument according to claim 10 wherein the transition region has a substantially concave surface.
15. A surgical instrument according to claim 10 wherein a length of the proximal end region is longer than a combined length of the transition region and distal end region.
16. A surgical instrument according to claim 10 wherein the distal end region comprises a pair of fins projecting from sides of the handle.
