Abstract
A forceps having an outer tube extending from a proximal portion to a distal portion and defining a longitudinal axis. A reciprocating inner tube can be located within the outer tube and extend along the longitudinal axis. A stationary jaw can be coupled to the distal portion of the outer tube and a moving jaw can be pivotably moveable relative to the stationary jaw. The moving jaw can be engaged with a portion of the reciprocating inner tube such that translation of the reciprocating inner tube pivots the moving jaw relative to the stationary jaw between an open and closed position.
Claims20
A surgical instrument, comprising:
- an outer shaft extending between a proximal portion connected to a handpiece and a distal portion, the outer shaft defining a longitudinal axis;
- an inner shaft located at least partially within the outer shaft and extending along the longitudinal axis, the inner shaft comprising:
- a projection located at a distal portion of the inner shaft, the projection defining a plurality of openings extending at least partially into the projection;
- a first jaw connected to the distal portion of the outer shaft;
- and
- a second jaw pivotably connected to at least one of the outer shaft and the first jaw, the second jaw comprising:
- a pair of flanges engageable with the projection of the inner shaft, each of the pair of flanges including a tooth located at least partially within one of the plurality of openings, the inner shaft translatable relative to the outer shaft to move the tooth of each of the pair of flanges to move the second jaw relative to the first jaw between an open position and a closed position.

A surgical instrument, comprising:
- an outer shaft extending between a proximal portion connected to a handpiece and a distal portion, the outer shaft defining a longitudinal axis;
- an inner shaft located at least partially within the outer shaft and extending along the longitudinal axis, a distal projection defining a first plurality of openings and a second plurality of openings;
- a first jaw fixed to the distal portion of the outer shaft;
- and
- a second jaw pivotably connected to at least one of the outer shaft and the first jaw, the inner shaft translatable relative to the outer shaft to move the second jaw relative to the first jaw between an open position such that the first jaw and the second jaw are at least partially separated and a closed position such that the first jaw and the second jaw are at least partially engaged, the second jaw comprising:
- a first flange include a first pair of teeth engaged with the first plurality of openings and the first pair of teeth movable by the inner shaft;
- and
- a second flange including a second pair of teeth engaged with the second plurality of openings and the second pair of teeth movable by the inner shaft to, together with the first pair of teeth, move the first jaw and the second jaw between the open position and the closed position.
