    摘要： A surgical instrument which has override protection when excessively thick tissue is attempted to be clamped between opposed jaws of an end effector is disclosed. The instrument includes a frame, a shaft extending from the frame, an end effector connected to the shaft distal end which includes movable, opposed jaws for clamping tissue therebetween, a clamping trigger, a resilient spring element fixed to the trigger, an actuator which translates movement from the clamping trigger to the movable jaws for clamping tissue, and an engaging element which is biased by the spring element against the actuator. When routine forces are applied by the user as the clamping trigger is moved to clamp tissue between the jaws, the engaging element causes the actuator to move in a forward direction for corresponding movement of the jaws from an open to a closed position. If excessive loads are applied, then the resilient spring element is compressed, and the engaging element is correspondingly released from its engagement with the actuator. Accordingly, further movement of the clamping trigger will not cause further translation of the actuator in the forward direction. Therefore, excessive loads are prevented, and the component parts of the instrument will be prevented from breaking. The invention is also applicable to actuators used for other functions such as stapling and cutting tissue.

    摘要： A surgical stapler having an end effector with a reduced stacking height for its components to decrease the diameter of a trocar cannula or other access device during minimally invasive surgery is disclosed. The end effector includes an elongated channel containing a staple cartridge and an anvil movable toward and away from the channel. The anvil is movable to first, second and third fixed positions relative to the channel. The first fixed position is a closed position which eliminates clearance between the anvil and cartridge. The second fixed position is an open position for inserting tissue between the anvil and cartridge. The third fixed position is a clamped position where a tissue-clamping gap exists between the anvil and cartridge to properly clamp tissue. The elimination of clearance between the anvil and cartridge of the first fixed position of the anvil reduces the stacking height, and therefore enables the user to insert the stapler through a smaller diameter access opening.

    摘要： A surgical instrument, illustrated as an endoscopic surgical stapler, includes first and second operating linkages respectively operatively connected with first and second operating levers pivotally mounted on a frame of the instrument. An improved mounting arrangement is provided for the operating levers in the form of first and second mounting bosses. The mounting bosses are formed separately in order to isolate forces exerted thereon by the operating levers attendant to use of the instrument.

    摘要： An external fixator system includes a fixation bar, a fixation pin, and a clamp assembly. The clamp assembly includes a first jaw pair, a second jaw pair, and a first spring insert. The first jaw pair has a first upper jaw component and a first lower jaw component that collectively define a first passage configured to receive the fixation bar. The second jaw pair has a second upper jaw component and a second lower jaw component that collectively define a second passage configured to receive the fixation pin. The first spring insert is positioned within the first passage and interposed between the first upper jaw component and the first lower jaw component. Advancement of the fixation bar into the first passage causes deflection of the first spring insert
