  • Alignment pin assembly for surgical stapler
    Patent number: 11744584
    Abstract: A surgical stapling instrument includes an elongate body portion defining a longitudinal axis, an end effector supported on a distal portion of the elongated body portion, and a deployment member extending from the elongate body portion into the end effector. The end effector includes a housing having a base portion and a jaw portion, an anvil assembly supported on the jaw portion, and a cartridge assembly releasably supported on the base portion. The cartridge assembly includes an alignment pin assembly. The deployment member includes a distal portion supporting an abutment member and is movable between a retracted position and an advanced position. The abutment member is releasably coupled to the alignment pin assembly when the deployment member is in the retracted position and is fixedly secured to the alignment pin assembly when the deployment member is moved from the retracted position.

  • Surgical stapling instrument and associated trigger mechanisms
    Patent number: 11617578
    Abstract: A trigger mechanism for a surgical instrument, particularly, a surgical stapling instrument provides significant mechanical advantages by increasing the length of the firing stroke of the surgical instrument while reducing the degree of movement of the trigger associated with the trigger mechanism. The trigger mechanism also reduces the forces required to actuate the trigger thereby enhancing usability and minimizing operator fatigue.
