Abstract
Forceps can include a drive pin, an outer tube, a first jaw, a second jaw, and an inner shaft. The outer tube can extend along a longitudinal axis. The first jaw can be pivotably connected to the outer tube. The first jaw can include a first flange that can be located at a proximal portion of the first jaw. The first flange can include a first chamfered edge configured to limit extension of the first flange laterally beyond an outer surface of the outer tube when the first jaw is in a closed position. The inner shaft can be located within the outer tube and can extend along the longitudinal axis.
Claims20
A forceps comprising:
- a drive pin;
- an outer tube extending along a longitudinal axis;
- a first jaw pivotably connected to the outer tube, the first jaw including a first flange located at a proximal portion of the first jaw, the first flange including a first chamfered edge extending at a nonzero angle from a laterally outer surface of the first flange to an upper edge of the first flange, the first chamfered edge configured to limit extension of the first flange laterally beyond an outer surface of the outer tube when the first jaw is in a closed position;
- a second jaw connected to the outer tube;
- and an inner shaft located within the outer tube and extending along the longitudinal axis, the inner shaft connected to the first flange, via the drive pin, the inner shaft translatable along the outer tube to drive the drive pin and the first flange to move the first jaw between open and closed positions.

A forceps comprising:
- a drive pin;
- an outer tube extending along a longitudinal axis;
- a first jaw pivotably connected to the outer tube, the first jaw including a first flange and a second flange each located at a proximal portion of the first jaw, the first flange and the second flange respectively including a first chamfered edge extending at a nonzero angle from a laterally outer surface of the first flange to an upper edge of the first flange, and a second chamfered edge extending at a nonzero angle from a laterally outer surface of the second flange to an upper edge of the second flange, the first chamfered edge and the second chamfered edge each configured to limit extension of the first flange and the second flange laterally beyond an outer surface of the outer tube when the first jaw is in a closed position;
- a second jaw pivotably connected to the outer tube, the second jaw including a third flange and a fourth flange each located at a proximal portion of the second jaw;
- and an inner tube located within the outer tube and extending along the longitudinal axis, the inner tube connected to the first flange, the second flange, the third flange, and the fourth flange via the drive pin, the inner tube translatable along the outer tube to drive the drive pin and the first flange, the second flange, the third flange, and the fourth flange to move the first jaw and the second jaw between open and closed positions.
