摘要： A surgical instrument end effector includes a first jaw configured to receive a staple cartridge and a second jaw that includes an anvil having a plurality of staple forming pockets. The first and second jaws are operable to clamp and staple tissue positioned therebetween. A tip member is movably disposed at a distal end of the anvil and is configured to toggle relative to the anvil between a first discrete position and a second discrete position. The tip member in the first discrete position is oriented angularly toward the first jaw, and the tip member in the second discrete position is oriented angularly away from the first discrete position.

摘要： A surgical clip applier comprising an electric motor system is disclosed. The electric motor system is configured to drive a clip firing system of the surgical clip applier. The surgical clip applier further comprises a control system configured to control the electric motor system. The control system is configured to monitor a strain gauge circuit to assess the crimping force experienced by the clip firing system. In at least one instance, one or more strain gauges (71720, 71730) are mounted to a drive shaft and/or jaw of the clip firing system. The control system modifies the operation of the surgical clip applier when the voltage of the strain gauge circuit exceeds and/or falls below a threshold. In at least one instance, the control system modulates the width, or duration, of voltage pulses applied to the electric motor system to control the speed of the electric motor system.

摘要： A surgical stapler that includes a body, a shaft extending from the body, and an end effector in communication with the shaft. The end effector is operable to compress, staple, and cut tissue. The end effector includes a first jaw; a second jaw opposed from the first jaw, and a tip member. The first and second jaws are operable to transition from an open state to a closed state to clamp tissue therebetween. The tip member is coupled with a distal end of the first jaw. The tip member is selectively rotatable along a rotation axis to toggle between a first discrete position and a second discrete position. The tip member in the first discrete position is configured to assume a first orientation relative to the second jaw, and the tip member in the second discrete position is configured to assume a second orientation relative to the second jaw.
