摘要： A surgical apparatus comprises a body, a user input feature, a shaft assembly, an end effector, and a blade cooling system. The end effector comprises a clamp arm and an ultrasonic blade that may be coupled with an ultrasonic transducer. The clamp arm is configured to pivot toward and away from the ultrasonic blade. The cooling system is operable to deliver liquid coolant to the ultrasonic blade to thereby cool the ultrasonic blade. The user input feature is operable to both actuate the clamp arm and actuate the cooling system.

摘要： An apparatus includes a body, a shaft assembly, and an end effector. The end effector includes an ultrasonic blade and a clamp arm assembly. The ultrasonic blade is in acoustic communication with an acoustic waveguide of the shaft assembly. The clamp arm assembly is pivotable toward and away from the ultrasonic blade. The clamp arm assembly includes a first electrode and a second electrode. The first and second electrodes are operable to cooperate to apply bipolar RF energy to tissue.

摘要： A surgical stapler including an anvil, a staple cartridge, and a buttress material removably retained to the anvil and/or staple cartridge. In various embodiments, the staple cartridge can include at least one staple removably stored therein which can, when deployed, or fired, therefrom, contact the buttress material and remove the buttress material from the anvil and/or staple cartridge. In at least one embodiment, the anvil can include at least one lip and/or groove configured to removably retain the buttress material to the anvil until deformable members extending from the surgical staple are bent by the anvil and are directed toward and contact the buttress material.

摘要： An apparatus comprises a body, a shaft assembly, an end effector, and a shield member. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is configured to vibrate at an ultrasonic frequency. The clamp arm is movable toward the ultrasonic blade to compress tissue against the ultrasonic blade. The shield member is selectively movable from a first position to a second position in response to movement of the clamp arm toward the ultrasonic blade. The shield member is configured cover at least a first portion of the ultrasonic blade in the first position. The shield member is configured to uncover the first portion of the ultrasonic blade in the second position.

摘要： An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide comprises a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section comprises a plurality of body portions aligned along the longitudinal axis and a flexible locking member. The flexible locking member is operable to secure the body portions in relation to each other and in relation to the shaft. The end effector comprises an ultrasonic blade in acoustic communication with the waveguide. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis.

摘要： Methods and devices for controlling motorized surgical devices are provided. In general, the methods and devices can allow a surgical device to grasp and cut tissue. In some embodiments, the device's motor can begin providing power for grasping and/or cutting tissue in response to an output from the device's sensor, the device can adjust power provided by the motor based on whether the device is clamping tissue or is being fired, the device can adjust an amount of power provided by the motor based on an amount of user-applied force to the device's actuator and/or can control drive direction of the motor based on the amount of the force, the device can maintain a force applied to the device, the device can self-shift the motor, and/or the device can adjust an amount of power provided to the device's end effector based on a degree of the end effector's closure.

摘要： A detachable motor-powered surgical instrument. The instrument may include a housing that includes at least one engagement member for removably attaching the housing to an actuator arrangement. A motor is supported within the housing for supplying actuation motions to various portions of a surgical end effector coupled to the housing. The housing may include a contact arrangement that is configured to permit power to be supplied to the motor only when the housing is operably attached to the actuator arrangement.
