An example end effector for a surgical device may include a first jaw, a second jaw, and an articulating mechanism operable to move the first jaw between an open position, an intermediate position, and a closed position. An example articulating mechanism may include a first jaw mount coupled to the first jaw so that movement of the first jaw mount along a path causes rotation and translation of the first jaw mount and the first jaw. A pivotably mounted crank may operably couple an actuator linkage to the first jaw mount so that moving the actuator linkage rotates the crank, and rotation of the crank may move the first jaw mount along the path.

  • Patent number: 11653922
    Abstract: A surgical stapling device includes a tool assembly and a drive assembly for actuating the tool assembly. The tool assembly includes a cartridge assembly having a staple cartridge and an anvil assembly that supports a lockout mechanism. The staple cartridge includes a cartridge body and an actuation sled and knife assembly that includes an actuation sled and a knife. The actuation sled and knife assembly is movable in relation to the cartridge body to eject staples from the cartridge body and to cut tissue. The anvil assembly supports a lockout mechanism that includes a lockout member that is movable between a locked position and an unlocked position. The drive assembly is movable from a retracted position to an advanced position to move the actuation sled and knife assembly from its retracted position to its advanced position. In the locked position, the lockout member obstructs movement of the drive assembly from its retracted position towards its advanced position.

  • Patent number: 11642129
    Abstract: The present disclosure provides a surgical instrument, such as a tissue sealing instrument, having a staple cartridge with a staple pusher and a staple; and a drive member configured to translate distally through the instrument. The drive member includes a lateral projection configured to engage the staple pusher and drive the staple into tissue. The lateral projection of the drive member has a height substantially less than the height of the staple cartridge, thereby requiring less clearance as it translates through the staple cartridge. In addition, the lateral projection has a smaller footprint than conventional drive members resulting in a more compact distal tip on the staple cartridge, which allows for a more compact and maneuverable surgical instrument.
