Abstract: A surgical device comprising: a closure assembly including: (a) a movement unit including: a bar that moves in a direction of a prescribed motion; (b) a latch unit including: (i) a latch plate including a hook latch that selectively receives the bar, the latch plate being movable in the direction of the prescribed motion between (A) a lockable state where the hook latch is engageable by the bar of the movement unit, and (B) an unlockable state where the bar does not reach the hook latch or the hook latch is moved out of alignment with the prescribed motion so that the hook latch is not engaged by the bar; and (ii) a stop that restricts movement of the movement unit relative to the hook latch.

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.

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.

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.

Abstract: Medical devices include a ground link, a first actuator pivotably coupled to the ground link and a first movable element operatively coupled to the first actuator by a linkage. The linkage including: the ground link; a second link that is pivotable with respect to the ground link; a fourth link that is pivotable with respect to the ground link; and a third link having a main body extending from a first portion to a second portion and a blocking tab extending away from the main body. The medical device further including a second actuator operatively coupled to the ground link, the second actuator having a blocking surface including a blocking tab that is positioned to engage with at least a portion of the blocking surface of the second actuator to limit movement of the second actuator until the first actuator is at least partially actuated.
