  • Publication number: 20240108372
    Abstract: A surgical device comprising: a closure assembly including: (a) a latch unit comprising: (A) a hook latch, having a home position, (B) a forward bias constraint, (C) a rearward bias constraint, and (D) a bias member extending between the forward bias constraint and the rearward bias constraint so that the bias member has a pre-load when the hook latch is in the home position; (b) a movement unit including a bar that is movable relative to the latch unit so that the bar is movable in a prescribed motion into contact with the latch unit to create a locked state; and wherein the bar moves into contact with the hook latch driving the hook latch in a first direction, away relative to the home position, and then the hook latch is moved by the bar in a second direction relative to the home position, and a loading of the bias member is increased from the pre-load when the hook latch is moved in either the first direction away from the home position or the second direction away from the home position.

  • Publication number: 20220409226
    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.

  • Publication number: 20210346044
    Abstract: A forceps includes jaws, a first shaft having a first slot, a second shaft extending along the first shaft and having a second slot, and a rod that extends along the second shaft. The rod has a third slot including a locking portion and a guide track portion. A pin extends through the first slot, the second slot, and the third slot to prevent deployment of the rod when the pin is in the locking portion and to permit deployment of the rod when the pin is in the guide track portion. A first actuator produces relative movement of the first and second shafts to move the jaws relative to each other and move the pin from the locking portion to the guide track portion of the third slot. A second actuator produces movement of the rod to deploy the rod when the pin is in the guide track portion.
