Abstract
A surgical instrument includes an elongate body defining a longitudinal axis, an actuation rod extending through the elongate body and a tool assembly coupled to the elongate body. The tool assembly includes a coupling member coupling the tool assembly to the elongate body and a tool portion pivotally associated with the coupling member. The tool portion includes a projection member including a blunt end portion and a cutting member extending distally outward from the projection member. The tool portion is operatively coupled to the actuation rod. Translation of the actuation rod causes pivotal movement of the tool assembly.
Claims20
A surgical instrument comprising:
- an elongate body defining a longitudinal axis;
- an actuation rod extending through the elongate body;
- and
- a tool assembly coupled to the elongate body, the tool assembly including:
- a coupling member coupled to the elongate body,
- a tool portion pivotally associated with the coupling member, the tool portion including a projection member including a substantially blunt end portion and a cutting member extending distally outward from the projection member, the tool portion operatively coupled to the actuation rod, wherein translation of the actuation rod causes pivotal movement of the tool portion.
A surgical instrument comprising:
- a handle assembly including an actuation knob and a slider;
- an elongate body defining a longitudinal axis and extending distally from the handle assembly;
- a tool assembly coupled to the elongate body, the tool assembly including:
- a coupling member, and
- a tool portion pivotally associated with the coupling member, the tool portion including a projection member including a blunt end portion and a cutting member connected to the projection member;
- a sheath slidably disposed in the coupling member, the sheath is movable between a retracted position in which the sheath is concentrically disposed within the coupling member and an extended position in which the sheath encloses the tool portion;
- an actuation rod extending through the elongate body, the actuation rod operatively interconnecting the actuation knob with the tool portion;
- and
- a translation rod operatively interconnecting the sheath with the slider, wherein translation of the actuation rod pivots the tool portion and translation of the translation rod moves the sheath between the refracted and extended positions.
