Abstract: A suction irrigator includes a drive housing, a flow control system arranged within the drive housing and including a flow manifold that houses an internal valve, and a drive input rotatably mounted to the drive housing. A capstan assembly is arranged within the drive housing and is operatively coupled to the flow manifold such that rotation of the drive input actuates the capstan assembly and thereby operates the internal valve between closed and open positions. A button is mounted to the drive housing and operatively coupled to the flow manifold such that manually depressing the button operates the internal valve between the closed and open positions. A decoupling mechanism mechanically decouples the button from the capstan assembly when the button is manually pressed such that manual movement of the button fails to backdrive the drive input or a motor operable to drive the drive input.

Abstract: Systems and subsystems for cutting and stapling tissue are disclosed. More specifically, the present disclosure relates to systems, devices, and subsystems for attachments for robotic surgeries. The surgical instrument includes a transection subsystem comprising a rotatable shaft having a lumen, a firing rod extending at least partially through the lumen, a firing rack coupled to a proximal end of the firing rod, the firing rod being rotationally independent of the firing rack, and a firing gear engaged with the firing rack. Rotation of the firing gear moves the firing rack and the firing rod axially.

Abstract: Various ultrasonic instruments are disclosed. The ultrasonic instruments include structures configured to indicate the cutting length of the instruments, detect when grasped tissue has extended beyond the cutting length of the instrument, and prevent tissue from extending beyond the cutting length. Several techniques for each types of structures are disclosed.

Abstract: Aspects of the present disclosure include various ultrasonic surgical instruments. At least one disclosed surgical instrument includes a waveguide including a blade and a transducer base plate. The transducer base plate may be coupled to the waveguide to define a tapered joint at an interface between the waveguide and the transducer base plate. The transducer base plate may include first and second sides defining corresponding first and second flat faces configured to receive first and second piezoelectric elements. The first and second piezoelectric elements are configured to operate in a D31 mode.
