A gyroscopic stabilizer configured to stabilize a surgical instrument relative to a patient includes a frame having a central axis and a hub configured to releasably couple with the surgical instrument. A first gyroscope assembly is coupled with a first frame portion and a second gyroscope assembly is coupled with a second frame portion. Each gyroscope assembly includes a gimbal pivotably coupled with the respective frame portion about a precession axis, a motor, and a rotor rotatably coupled with the motor about a spin axis perpendicular to the respective precession axis. Each gyroscope assembly is operable generate a torque in a torque plane that contains the respective spin axis and the respective precession axis. The torques are configured to resist rotation of the gyroscopic stabilizer relative to the patient about respective device axes that are perpendicular to the central axis and to one another.

Stabilizer for surgical shafts or cannulas

A bone cutting surgical instrument includes features to mitigate heat generation during use. Excessive heat can be detrimental to bone health as well as to the instrument itself. In one example a liquid dispensing feature provides a flow of cooling liquid to an ultrasonic blade via a lumen in a waveguide of the instrument. In another example, the blade has a serrated edge with a plurality of teeth arranged in a pattern to provide dimension and space during cutting actions. In another example, the blade has an oversize distal portion that creates an oversize slot when cutting to avoid excessive contact between the cut bone and proximal portions of the blade. In another example the blade includes an irrigation slot and also a micro slot in a distal end of the blade that connects with the irrigation slot.

Ultrasonic surgical instrument blade with heat reduction feature

An instrument includes an ultrasonic blade, a first fluid port, an irrigation member, a second fluid port, and a fluid communication assembly. The ultrasonic blade defines a distal opening. The ultrasonic blade is operable in a first mode to emulsify tissue that is distally positioned relative to the ultrasonic blade. The ultrasonic blade is further operable in a second mode to transect and seal tissue that is transversely positioned relative to the ultrasonic blade. The first fluid port is in communication with the distal opening of the ultrasonic blade. The irrigation member is positioned adjacent to the distal end of the ultrasonic blade. The second fluid port is in communication with the irrigation member. The fluid communication assembly is configured to couple the first fluid port with a fluid source, couple the first fluid port with a suction source, and couple the second fluid port with the fluid source.

Features to promote removal of debris from within ultrasonic surgical instrument

Surgical systems and methods are provided for controlling actuation and movement of various surgical devices.

Electrically-powered surgical systems providing fine clamping control during energy delivery

Electrically-powered surgical systems employing variable compression during treatment

An ultrasonic surgical instrument includes a body, a shaft, an ultrasonic transducer, a waveguide, and an end effector coupled to a distal end of the shaft. A rotation knob is rotatably coupled to the body and is configured to rotate the shaft, the waveguide, and the end effector together relative to the body. A torque transfer structure is positioned radially outwardly of and in direct contact with the waveguide at an acoustic node thereof. The torque transfer structure is rotationally fixed relative to the waveguide and is configured to rotationally couple the waveguide with the shaft and the rotation knob. The waveguide includes a first axial constraining feature defining a distally facing surface, and the torque transfer structure includes a second axial constraining feature defining a proximally facing surface configured to abut the distally facing surface to constrain the waveguide axially relative to the torque transfer structure and the body.
