An apparatus comprises an end effector, a shaft assembly, and an interface assembly. The end effector is operable to manipulate tissue, the shaft assembly is in communication with the end effector and a portion of the shaft assembly extends proximally from the end effector. The interface assembly is in communication with the shaft assembly. The interface assembly comprises a housing portion, a shaft cartridge, and a base portion. The housing portion can engage the shaft cartridge. The shaft cartridge is able to rotate and articulate the end effector, and the shaft assembly extends from the shaft cartridge. The base portion and the housing portion are able to enclose the shaft cartridge.

A surgical instrument includes an ultrasonic waveguide extending through a body assembly. An ultrasonic blade connects to the ultrasonic waveguide. A clamp arm assembly of the surgical instrument is able to move from an opened position for receiving a tissue toward a closed position for clamping the tissue. The clamp arm assembly includes a clamp body and a clamp pad facing the ultrasonic blade. A clamp arm actuator of the surgical instrument is able to move from a first position toward a second position to direct the clamp arm assembly from the opened position toward the closed position. A modular coupling of the surgical instrument connects to the clamp pad such that at least the clamp pad can be disconnected relative to the ultrasonic blade for replacement thereof.

The disclosed technology is directed to a treatment instrument having a vibration generating device and a handle for operation. The vibration generating device comprises a housing and a generator including a transducer disposed within the housing. The transducer generates vibration by using electric energy and a first electric contact disposed on the housing. A connector is rotatable about a predetermined rotational axis with respect to the housing of the generator. A coupler is disposed in the connector and having a second electric contact rotatable about the predetermined rotational axis with respect to the first electric contact in a state in which an electric connection of the second electric contact to the first electric contact is maintained. The connector further includes a conductive member forming a part of an electric path of a current that flows based on an operating input at an operating member provided on the handle.

A surgical instrument comprising a jaw assembly is disclosed. The surgical instrument further comprises a motor-driven drive system configured to open the jaw assembly. The surgical instrument also comprises a control system configured to control the drive system and, also, control a power supply system configured to supply electrical power to electrodes defined in the outer surface, or outer surfaces, of the jaw assembly. In use, the surgical instrument can be used to apply mechanical energy and electrical energy to the tissue of a patient at the same time, or at different times. In certain embodiments, the user controls when the mechanical and electrical energies are applied. In some embodiments, the control system controls when the mechanical and electrical energies are applied.

A suture device is utilized in forming a purse string suture during, e.g., laparoscopic end to end anastomosis procedure, to effect joining of two opposing intestinal sections. The suture device is utilized in other procedures such as, e.g., transanal total mesorectal excision (TaTME) for removal of low rectal and ultra-low rectal tumors and preservation of anal sphincters to avoid permanent stomas. In particular, the suture device is utilized in forming surgical stitches used to close an internal anal structure or to narrow a passage for performing further transanal dissection to create total mesorectal excision.

A surgical tool for use with a robotic system that includes a tool drive assembly that is operatively coupled to a control unit of the robotic system that is operable by inputs from an operator and is configured to robotically-generate output motions. A drive system is configured to interface with a corresponding portion of the tool drive assembly for receiving the robotically-generated output motions and applying the output motions to a drive shaft assembly which is configured to apply control motions to a surgical end effector operably coupled thereto. A manually-actuatable control system operably interfaces with the drive shaft assembly to facilitate the selective application of manually-generated control motions to the drive shaft assembly.

An instrument drive connector includes a housing assembly, an elongated shaft extending distally from the housing assembly, and a first drive assembly at least partially disposed within the housing assembly and the elongated shaft. The first drive assembly includes a first drive screw, a first input drive coupler non-rotatably coupled to a proximal end of the first drive screw, a first drive nut threadedly engaged with a threaded body portion of the first drive screw and longitudinally movable relative thereto in response to rotation of the first drive screw, and a locking link. The locking link includes an elongated body having a proximal end portion coupled to the first drive nut and longitudinally movable relative thereto between a proximal non-locking position and a distal locking position, and a distal end portion including a switch actuation assembly including a switch actuating arm biased towards the distal locking position.

An accessory device may be used in combination with a thrombectomy catheter. The accessory device may be configured to deflect a distal portion of the thrombectomy catheter and/or disrupt a lesion in a vessel.
