ERGONOMIC SURGICAL INSTRUMENTS

摘要

A surgical instrument comprising a trigger configured to be actuated by a proximally directed force and by a distally directed force. The trigger may comprise a proximal trigger portion having a first length and a distal trigger hook comprising a distal portion having a second length. The second length may be less than the first length. The distal trigger hook may be coupled to the proximal trigger portion.

1. A surgical instrument comprising:
a handle assembly, the handle assembly comprising:
a housing having a proximal end and a distal end, wherein the housing defines a proximal opening at the proximal end of the housing and a distal opening at the distal end of the housing, and wherein the distal and proximal openings are positioned on a longitudinal axis;a handle extending downwardly from the housing away from the longitudinal axis, the handle defining a proximal contact surface, a saddle surface positioned between the proximal contact surface and the housing, wherein at least one component selected from the group consisting of the handle and the housing defines a stabilization tail extending proximally from the handle and the housing; a trigger pivotably attached to the handle assembly and pivotably movable relative to the handle from an open position away from the handle to a closed position towards the handle; and a trigger hook fixedly coupled to the trigger to move with the trigger relative to the handle from the open position to the closed position, wherein the trigger and the trigger hook define an aperture therebetween, and wherein the trigger and trigger hook are substantially parallel to the handle when the trigger and trigger hook are in the closed position.
