Abstract
Abstract A handle for a laparoscopic instrument is provided for manipulating a distal laparoscopic tool. The handle includes a casing, a pivot handle pivotally attached to the casing, and an actuating shaft mechanism extending outward from the casing. Attached at the distal end of the actuating shaft opposite the casing is the laparoscopic surgical tool. The actuating shaft mechanism is longitudinally movable in a first direction by a pivotal movement of the pivot handle for manipulating the laparoscopic tool. A detent carried by the casing allows movement of the shaft longitudinally in the first direction while restraining longitudinal movement of the shaft in a second opposite direction. A thumb wheel attached to the actuating shaft mechanism allows the actuating shaft mechanism to be rotated for further manipulating the laparoscopic tool.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
187 words
A handle for a laparoscopic instrument, comprising: a) an elongated casing defining a longitudinal axis and having a proximal end and a distal end; b) an outer shaft extending distally from the distal end of the elongated casing; c) an actuating shaft concentrically positioned and interconnected within the outer shaft, the actuating shaft at least partially supported within the elongated casing for longitudinal movement in a first direction and a second direction, the actuating shaft extending distally from the elongated casing; d) a gripping member pivotably mounted to the elongated casing; e) a link member having one portion pivotably connected to the gripping member and a second portion pivotably connected to the actuating shaft for moving the actuating shaft in the first direction when the gripping member is pivoted toward the elongated casing in a corresponding first direction; f) biasing means to normally bias the actuating shaft in the second direction; and g) detent means disposed on the elongated casing and structured for allowing incremental movement of the actuating shaft in the first direction while restraining the longitudinal movement of the actuating shaft in the second direction.
