A system for preventing unwanted tissue migration in surgical staplers includes a surgical stapler having an end effector including an upper jaw and a lower jaw. A distal end of the upper jaw is connected to a distal end of the lower jaw, and a proximal end of the upper jaw is connected to a proximal end of the lower jaw. First and second tissue stops are formed on the distal and proximal ends of the lower jaw, respectively. The second tissue stop and the proximal end of the upper jaw define a no cut zone when the surgical stapler is in an open position. The surgical stapler also includes a tissue cutting device disposed within the lower jaw for resecting tissue. The system also includes a warning, blocking, impeding, or barrier forming device for preventing the unwanted migration of tissue into the no tissue zone.

The anvil has an anvil face and a first staple pocket defined by the anvil face, where the first staple pocket comprises a first cup and a second cup for staple formation. The cartridge has a first staple, the first staple having a first open leg with a first tip, a second open leg with a second tip, and a first crown coupling the first open leg and the second open leg, and a first driver. The first staple, once deployed by the first driver and deformed by the first staple pocket, comprises the first tip and the second tip crossing the first midline axis of the first crown in a formed configuration.

A surgical instrument including a system for stopping a beam of the surgical instrument from impacting a distal pin when reversing a knife is disclosed. A knife assembly of the surgical instrument comprises the knife, the beam, and a firing nut. A firing lead screw can drive the firing nut distally and proximally. A firing screw compression spring extends along the firing lead screw and applies a load proximally on the firing nut when the firing nut is driven toward a distal end of the firing lead screw.

An end effector for use by a surgeon to staple an anatomical structure of a patient during a surgical procedure includes an anvil and a cartridge. Each of the anvil and the cartridge has a face that is positionable on the anatomical structure. The anvil is coupled to the cartridge at first and second ends. The anvil is movable relative to the cartridge to define a first gap between the faces at the first ends that is different from a second gap between the faces at the second ends.

A clamp for a medical procedure includes a first clamp member, a second clamp member, a hinge, a biasing member, a shaft, and an actuator. The hinge couples the first ends of the first and second clamp members such that the first clamp member is pivotable relative to the second clamp member. The biasing member couples the second ends of the first and second clamp members and is configured to apply a clamping force. The distal end of the shaft and the biasing member are fixedly coupled with at least one of the first clamp member or the second clamp member for a duration of the medical procedure. The actuator is operatively coupled with the biasing member such that the actuator selectively tensions the biasing member to provide the clamping force.
