Abstract
An end effector for use by a surgeon to staple an anatomical structure of a patient during a minimally invasive procedure, the anatomical structure having a first side and a second side, the end effector including an anvil, a cartridge that is configured to house a plurality of staples, and a compression mechanism that movably couples the anvil to the cartridge.
Claims16
An end effector for use by a surgeon to staple an anatomical structure of a patient during a minimally invasive procedure, the anatomical structure having a first side and a second side, the end effector comprising:
- an anvil that includes a proximal end, a distal end, and a face, having a longitudinal axis, that is positionable on the first side of the anatomical structure;
- a cartridge that is configured to house a plurality of staples and that includes a proximal end, a distal end, and a face, having a longitudinal axis, that is positionable on the second side of the anatomical structure;
- a compression mechanism that movably couples the proximal end of the anvil to the proximal end of the cartridge;
- a distal hinge including a pin that pivotally couples the distal end of the anvil and the distal end of the cartridge, wherein the pin is transverse relative to the longitudinal axis of the cartridge and the longitudinal axis of the anvil;
- wherein each of the anvil and the cartridge is insertable through a trocar, and the end effector is remotely operable from outside the patient with at least a portion of one of the anvil and the cartridge being movable toward the other to clamp the end effector to the anatomical structure.

- a cartridge that is configured to house a plurality of staples and that includes a first end, a second end, and a face, having a longitudinal axis, that is positionable on the second side of the anatomical structure;
- and
- a compression mechanism that movably couples the first end of the anvil to the first end of the cartridge, the compression mechanism comprising;
- a. a compression slide;
- and
- b. a compression pin operably configured to translate within the compression slide to compress the anatomical structure between the anvil and the cartridge;
- a distal hinge including a pin that pivotally couples the second end of the anvil and the second end of the cartridge, wherein the pin is transverse relative to the longitudinal axis of the cartridge and the longitudinal axis of the anvil;
- wherein each of the anvil and the cartridge is insertable through a trocar and the end effector is remotely operable from outside the patient with at least a portion of one of the anvil and the cartridge being movable toward the other to clamp the end effector to the anatomical structure.
