Bending tools and methods of use thereof
A single-patient-use disposable tool comprises a molded, single-piece body with a curved upper surface having a predetermined bend radius for bending a needle slidably disposed in a sheath. A distal end of the curved surface has a slot for insertion of a tip of a needle, while the proximal end of the curved surface has a guide member for slidably receiving the sheath. Two finger loops or similar ergonomic features allow the user to rotate the bending tool relative to the sheath to bend the needle about the predetermined bend radius. After completing the bend, the tool is removed from the needle and disposed of.
1. A bending tool for a needle having a shaft and a tip, the bending tool comprising:
a substantially flat body having a proximal end, a distal end and a longitudinal axis extending therebetween;
a first slot extending along a length of the body, a proximal end of the first slot having a first curved surface extending at an angle from the longitudinal axis, a distal end of the first slot configured to receive a tip of a needle to bend the tip of the needle along the first curved surface;
a second slot separate and apart from the first slot, the second slot extending across a width of the body, the second slot including a second curved surface extending at an angle from the longitudinal axis, the second slot configured to receive a shaft of the needle to bend the shaft along the second curved surface.
2. The bending tool of claim 1 , wherein the first slot includes a relief channel configured to provide clearance for one or more implants and/or suture disposed within the tip of the needle.
3. The bending tool of claim 1 , further comprising an angle limiter adjacent the first curved surface for limiting a maximum bend angle or bend radius of the needle.
4. The bending tool of claim 1 , wherein the first curved surface has a predetermined bend radius or bend angle.
5. The bending tool of claim 1 , wherein the body further comprises a textured gripping surface.
6. The bending tool of claim 1 , wherein the first slot includes a window for direct visualization of the needle.
7. The bending tool of claim 1 , wherein the second slot is configured to provide three contact points on the needle.
