摘要： A surgical stapling instrument for performing a circular anastomosis comprises a stapling head assembly, an actuator handle assembly, a shaft assembly, a safety latch, and a locking member. The stapling head assembly includes an anvil that moves relative to a staple holder and a staple driver to drive staples from the staple holder into tissue and against the anvil. The actuator handle assembly has a first actuator that controls motion of the anvil and a second actuator that controls motion of the staple driver. The shaft assembly couples the stapling head assembly to the actuator handle assembly. The safety latch prevents operation of the second actuator when the gap between the anvil and staple holder is outside a predetermined range. The locking member is configured to prevent adjustment of the anvil gap after the desired staple height has been set inside the predetermined range.

摘要： A surgical instrument includes a handle assembly having a trigger operable to fire a staple driver to staple tissue. The instrument includes a pointed rod to which an anvil may be coupled. An anvil detection feature is included to determine when the anvil is coupled to the rod. In some versions, the anvil detection feature comprises a translatable rod that inhibits a lockout feature from disengaging. In other versions, an anvil sensing tube is disposed about the pointed rod and interferes with actuation of the trigger in a first position. A recess in the tube permits trigger to actuate when the anvil sensing tube is in the second position. Alternatively, a resilient tab is coupled to the pointed rod and resists actuation of the staple driver. A trigger lockout assembly may include a spring-loaded button that “pops” out when a push rod is actuated, thereby freeing a pivotable lockout feature.

摘要： An apparatus includes an end effector, a shaft assembly including a translating drive member, and a drive assembly. The end effector includes a distally advancing cutting member and staple driver. The translating drive member is operable to actuate the end effector. The drive assembly is in communication with the translating drive member and includes a motor, a rotary drive member, a first link, and at least one toggle link. The rotary drive member is in communication with the motor. The first link is in communication with the rotary drive member. The at least one toggle link is in communication with the first link and the translating drive member. The rotary drive member is operable to convey linear motion to the first link. The first link is able to convey linear motion to the translating drive member.

摘要： A surgical circular stapler has a body, shaft, a stapling assembly, a motor, a cam assembly, and a firing assembly. The shaft extends distally from the body. The stapling assembly is secured to a distal end of the shaft. Longitudinal translation of the firing assembly causes the stapling assembly to drive a plurality of staples in a circular array to secure two lumens of tissue together. The stapling assembly may further drive a blade to sever any excess tissue interior of the circular array of staples. The motor is operable to rotate the cam assembly. Rotation of the cam assembly causes longitudinal translation of the firing assembly. A single rotation of the cam assembly is operable to drive the firing assembly from a proximal position to a distal position and back to a proximal position.
