A laparoscopic surgical instrument configured to be ergonomic and anthropometrically correct, the laparoscopic surgical instrument comprising: (a) an ergonomic handle configured to orient a hand of a surgeon in a functional position, the handle comprising a handle grip; (b) an actuating mechanism actuatable by a finger and supported by the handle, the actuating mechanism comprising an actuator shaft and a gearing assembly operable to displace the actuator shaft with a mechanical advantage upon actuation of a trigger by the surgeon; (c) a locking mechanism configured to lock the actuating mechanism in one of a plurality of positions, the locking mechanism comprising a release located in an anthropometrically correct position; and (d) a working shaft having a proximal end coupled to and operable with the actuator shaft, the working shaft having an elongate configuration and a distal working end configured to couple a surgical tool to be manipulated by the surgeon via the handle and the actuating mechanism to perform a surgical function.

Laparoscopic surgical instrument

A surgical devicewith an ergonomic handleand, an elongated tubular portionextending from the ergonomic handleto a functional end. The elongated tubular portionhas a longitudinal axis, and a finger actuatoris positioned substantially in line with this axis. Furthermore, the surgical devicemay also include a rodfunctionally disposed within the tubular portionalong the longitudinal axis. The rodmay be coupled proximally to the finger actuatorand distally to the functional end, such that bidirectional pressure applied by the user's finger to the finger actuatoralong the longitudinal axismanipulates the functional endin a bidirectional manner in response to or in a common direction to the bidirectional pressure. The surgical devicemay further comprise a ratcheting mechanismto lock the finger actuatorin a fixed position, thus locking the functional endin a fixed position. Additionally, the functional endmay be free to rotate around the longitudinal axis, and the elongated tubular portionmay be detachable from the ergonomic handle
