    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.

    Abstract: A surgical tool can include a shaft, a pin, an end effector, and a translating member. The shaft can define a longitudinal axis. The pin can be located at a distal portion of the shaft. The end effector can be connected to the shaft. The translating member can be positioned laterally inward of the shaft. The translating member can include a track and the pin can extend into the track to limit translation of the translating member along the longitudinal axis with respect to the end effector.

    Abstract: Forceps including a housing, a first body, a second body and a drive shaft. The first body has a passageway extending therethrough. The drive shaft extending through the passageway and connected to the first body such that the first body and the drive shaft are slidable with respect to the housing to drive jaws located at a distal portion of the drive shaft between an open position and a closed position. The second body having a second passageway. The drive shaft extending through the second passageway such that the second body is guided by the drive shaft and is slidable relative to the first body and the drive shaft to displace a blade shaft between a retracted position and an extended position.
