  • Publication number: 20190105069
    Abstract: Methods and devices for using surgical devices with articulating end effectors are provided. Surgical devices with articulating end effectors can provide rotary driven pivoting of the end effector. In some embodiments, the device can include a handle, a first and a second tube extending from the handle, the second tube disposed within the first tube, and an end effector that includes a pair of distal jaws configured to move in response to rotation of the first tube about a longitudinal axis thereof and rotation of the second tube about a longitudinal axis thereof. The jaws can move in two different ways depending on whether the first and second tubes are rotating in a same direction as one another or in different ways than each other. The jaws can open/close and articulate using the same mechanical mechanism. The device can be powered, or the device can be non-powered.

  • Publication number: 20180304056
    Abstract: A dilation catheter system is provided to dilate the ostium of a paranasal sinus or some other anatomical passageway (e.g., within the ear, nose, or throat, etc.). The system may include a dilation catheter, a dilator, a guide catheter, and an inflator. The dilation catheter may be positioned between the dilator and the inflator. The guide catheter is configured to guide the dilator into the affected passageway. The inflator may then be actuated to transfer fluid from the inflator, through the dilation catheter, and into the dilator. The transfer of fluid may inflate the dilator to an expanded state to open or dilate the affected passageway. The inflator may include a body, a plunger assembly, and locking features that selectively secure the position of the plunger assembly relative to the body by moving along a path that is transverse to a longitudinal axis defined by the plunger assembly.

  • Patent number: 10034684
    Abstract: A surgical instrument for cutting and coagulating tissue is provided that includes an elongate sheath and an ultrasonic blade. In one embodiment, an ultrasonic blade is positioned within a sheath such that movement of the sheath relative to the blade results in the dissection and/or coagulation of tissue therebetween. In another embodiment, an ultrasonic blade is positioned within a sheath such that movement of the blade relative to the sheath results in the dissection and/or coagulation of tissue therebetween. The size and shape of distal ends of the blade and sheath determine the size and shape of the tissue being cut and/or removed from a body.

  • Patent number: 10029125
    Abstract: A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, an end effector, and a rigidizing member. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The acoustic waveguide is coupled with the transducer. The articulation section is operable to flex to thereby deflect the end effector from a longitudinal axis defined by the shaft. The rigidizing member is operable to selectively rigidize the articulation section and thereby prevent deflection of the end effector by preventing flexibility of the articulation section. Such rigidization includes removing any “play” or other small movement that might otherwise be provided by the articulation section due to manufacturing tolerances and/or looseness between parts.

  • Patent number: 9986982
    Abstract: A biopsy device comprises a probe and a holster. The probe has a distally extending needle including a transverse tissue receiving aperture. A cutter is translatable relative to the needle to sever tissue protruding through the aperture. A thumbwheel is manually operable to rotate the needle to reorient the angular position of the aperture about the longitudinal axis defined by the needle. The thumbwheel is positioned obliquely with the longitudinal axis. A cable driven mechanism in the holster drives the cutter. A rotatable tissue sample holder is coupled with the probe, and has chambers configured to receive tissue samples communicated proximally through a lumen defined by the cutter. A piezoelectric motor in the holster drives the tissue sample holder.

  • Patent number: 9962182
    Abstract: In various embodiments, a surgical instrument for operation in an aqueous environment is provided. In at least one embodiment, the surgical instrument may include a hollow sheath and a blade disposed at least partially within the sheath. Coupled to the blade may be at least one ultrasonic transducer, which, in turn, may be coupled to a drive system. The drive system may be configured to deliver gross axial motions to the blade such that the blade translates with respect to the hollow sheath when the drive system is activated. Accordingly, tissue may be cut by the blade with gross axial movement of the blade and/or ultrasonic vibrational motion provided by the ultrasonic transducer(s). In alternative embodiments, the blade may be rotated axially instead of translated with respect to the hollow sheath.
