A surgical tool configured for operation in connection with a robotic system. The surgical tool includes a shaft and an end effector extending distally from the shaft. The end effector comprises a first jaw member and a second jaw member movable relative to the first jaw member from a closed position to an open position in response to at least one axial motion. In addition, the surgical tool includes a motor configured to generate at least one rotational motion and a motion conversion assembly operably coupled to the motor and the second jaw member, wherein the motion conversion assembly is configured to convert the at least one rotational motion to the at least one axial motion.

A powered surgical instrument comprising an end effector, a sensor configured to output a signal, an elongate shaft, and a handle is disclosed. The end effector comprises a first jaw, a second jaw movable relative to the first jaw, a channel, a staple cartridge, an anvil, and a firing member configured to be driven during a firing stroke. The firing member experiences a pushing force during the firing stroke and comprises a knife portion, a first camming member configured to engage the first jaw, a second camming member configured to engage and position the second jaw. The handle comprises a motor, a battery, means for detecting the pushing force of the firing member, and a control unit configured to receive the signal from the sensor. The control unit includes a microprocessor which utilizes a pulse width modulation circuit to control the motor based on the signal received from the sensor.

Forming a proximal anastomosis on an aortic wall includes method and instrumentation and apparatus for forming an aortic puncture and inserting into the vessel through the puncture a fluid-impervious sealing element with a protruding retainer. An anastomosis of a graft vessel over the puncture is partially completed with the retainer of the sealing element protruding through the partial anastomosis. The retainer facilitates removal of the sealing element from the partial anastomosis prior to completion of the procedure.

A system for performing an endoscopic procedure is provided. The system includes an actuation assembly having a handle assembly and a shaft assembly. The system also includes an end effector configured for selective and operative connection to a distal end of the shaft assembly. The system further includes a holder for selectively engaging the end effector and facilitating attachment of the end effector to the shaft assembly.

Example embodiments relate generally to surgical systems. The system may include a first arm assembly having a first arm assembly body. The system may also include a distal elbow joint assembly secured to a proximal end of the first arm assembly. The distal elbow joint assembly may be configurable to provide the first arm assembly with a first degree of freedom relative to a first axis. The system may also include a proximal elbow joint assembly secured to the distal elbow joint assembly. The proximal elbow joint assembly may be configurable to provide the first arm assembly with a second degree of freedom relative to a second axis. The second axis may be different from the first axis. The first degree of freedom may be different from the second degree of freedom.

Disclosed herein are various systems and methods for facilitating control of a tool or tools. The systems can allow a user to control multiple degrees of freedom. One such system allows a user to control multiple degrees of freedom of two tools simultaneously. Another such system allows a user to control multiple degrees of freedom with a single hand. Frames and rails for supporting and/or constraining movement of a tool or tools are also described herein.

A surgical instrument for use with a robotic system that has a control unit and a shaft portion that includes an electrically conductive elongated member that is attached to a portion of the robotic system. The elongated member is configured to transmit control motions from the robotic system to an end effector.

A surgical tool configured for operation in connection with a robotic system. The surgical tool includes a shaft and an end effector extending distally from the shaft.
