Cutting assembly for surgical instrument with clog reducing tip

A cutting assembly for a surgical instrument. A tube assembly includes an outer tube having an outer cutting window, and an inner tube coaxially disposed within and rotatable relative to the outer tube. The inner tube includes an inner cutting window such that the inner and outer cutting windows define a cutting window of the tube assembly. A portion of the inner tube distal a proximal boundary of the cutting window may define a distal region of the inner tube. A projection is within a lumen of the inner tube with at least a portion of the projection disposed within the distal region. The projection may be an insert. The projection occupies a volume of the distal region and/or reduces a cross-sectional area of the lumen distal to the proximal boundary. The projection reduces the size of material removed through the cutting window to reduce clogging of the tube assembly.

A surgical instrument (1000) includes an end effector assembly (200) including first and second grasping components (210, 220) each defining a tissue-contacting portion (214, 218, 224, 228). One or both of the first or second grasping components (210, 220) is movable relative to the other between an open position and a closed position. In the closed position, the first and second tissue-contacting portions (214, 218, 224, 228) cooperate to define a grasping area therebetween. One or both of the first or second grasping components (210, 220) is configured to apply energy from the tissue-contacting portion (214, 218, 224, 228) thereof to tissue disposed within the grasping area to treat tissue. The tissue-contacting portion (214, 224) of the first grasping component (210) defines a first opening (219) therethrough. The first opening (219) is disposed within the grasping area and in communication with a first lumen (118) defined at least partially through the first grasping component (210). The first lumen (118) is adapted to connect to a source of vacuum (300) to enable aspiration through the first opening (219).

A tube configured to be mounted on an outer side of a shaft of a treatment instrument includes a tube main body, and a convex portion that is provided along a longitudinal axis of the tube main body and is protruded inwards in a radial direction of the tube main body with respect to an inner peripheral surface of the tube main body.

Oscillating lithotripter

A lithotripter is provided for fragmenting a stone inside a patient's body. In one form, the lithotripter includes a motor having at least two modes of operation and is configured to produce first and second waveforms. A wave guide shaft is configured to transmit the first and second waveforms to the stone. In one form, at least one of the first and second waveforms is provided to the stone at a frequency that is about equal to a natural frequency of the stone. In a variation, the lithotripter may include an ultrasonic driver configured to produce an ultrasonic frequency waveform and a sonic driver configured to produce a sonic frequency waveform. The sonic driver is mechanically coupled to the ultrasonic driver. The ultrasonic driver and the sonic driver may be disposed within a driver housing. In another variation, the lithotripter may include a brushless DC motor.
