| Abstract: |
A hand held surgical needle holder for turning and gripping microsurgical needles. The needle holder is of the tweezer type with two spaced tongs having a cylindrical central portion. Pointed tips on the prongs are brought toward each other by pressure to grip the needle. One of the tips is hooked and extends beyond the end of the other tip member. The needle is held between the hooked surfaces as the cylindrical central portion is rotated to spin the needle in an arc.

What is claimed is:
1. A hand-held surgical tool for turning and gripping microsurgical curved needles having ends, said tool comprising:
- an elongated body for grasping by the user and having a generally cylindrical central portion for spinning about a longitudinal axis through said body,
- spaced upper and lower tips on said body adapted to be moved toward each other to grip the needle,
- said tips terminating in sharp pointed ends, one of said ends on said first tip being a hooked end and having a first curved surface for hooking under a microsurgical needle and for holding the needle while it pivots its ends downwardly,
- said second end having a shorter length than said hooked end,
- said hooked end on said first tip extending beyond said second end and extending across the longitudinal axis and over said second end,
- a second curved surface on the end of the second tip facing the first curved surface to engage a side of the microsurgical needle when the tips are moved together,
- said second curved surface engaging and rolling the needle along the first curved surface to swing the ends upwardly as the tips are brought to the closed gripping position, said needle being held between said curved surfaces as the cylindrical central section is turned to spin the microsurgical needle ends in an arc.
