End effector for a surgical device

A surgical instrument includes a reusable component and a disposable component selectively separable from and engagable with the reusable component. The disposable component includes an end effector and a mechanical actuator operable to induce mechanical movement of the end effector. The reusable component is configured for providing electrosurgical energy to the disposable component when engaged with the disposable component. A physical mating feature is configured to maintain engagement between the reusable and disposable components when the reusable and disposable components are engaged, and an electrical mating feature is configured to transmit electrical energy between the disposable and reusable components when the disposable and reusable components are engaged. All mechanical motion resulting from operation of the mechanical actuator may be contained within the disposable component.

Partitioned surgical instrument

Jaw design for a surgical instrument

An electrosurgical instrument has a movable tissue cutting mechanism, a first elongated shaft housing at least a proximal portion of the movable tissue cutting mechanism, and a pair of jaws for clamping tissue. Each jaw of the pair of opposing jaws is rotatable relative to the first elongated shaft, and the movable tissue cutting mechanism is slidable relative to the first elongated shaft. A first link has a distal end rotatably coupled to a proximal one of a pair of non-conductive bushings in the first jaw and a proximal end rotatably coupled to a second elongated shaft, the second elongated shaft interior of and translatable relative the first elongated shaft.

Electrosurgical sealer and divider

Yoke assembly for a surgical instrument

A device for directing energy to a target volume of tissue includes an inner conductor having a length and an outer conductor coaxially surrounding the inner conductor along the length. The outer conductor has a proximal portion and a distal portion. The distal portion of the outer conductor is provided with a number of apertures N defined therein for radiating energy, where N is an integer greater than 1, each aperture having a size and extending at an angle relative to a longitudinal axis of the outer conductor. At least one of the size and the angle of each aperture is varied in relation to the other apertures N&#x2212;1 such that the energy radiated along the distal portion is substantially uniform.

Leaky-wave antennas for medical applications

A medical device including one or more components positioned to contact contaminants during use of the medical device. The one or more components including one or more limited-use portions transitionable upon use from an initial state, wherein the limited-use portion(s) exhibits a clean appearance, to a used state, wherein the limited-use portion(s) exhibits a contaminated appearance that visually indicates to a user that the at least one component is not further usable.

Limited-use medical device

A method of performing a medical procedure is disclosed. The method includes: positioning an energy delivery device configured to deliver energy adjacent uric acid (UA) crystals having a resonance frequency; applying energy to tissue through the energy delivery device at a predetermined frequency thereby resonating the UA crystals; debulking at least a portion of the UA crystals; and removing at least a portion of the debulked UA crystals.

Energy-based treatment methods for refractory gout

A surgical instrument a reusable component and a disposable component selectively separable from and engagable with the reusable component. The disposable component includes an end effector and a mechanical actuator operable to induce mechanical movement of the end effector. The reusable component is configured for providing electrosurgical energy to the disposable component when engaged with the disposable component. A physical mating feature is configured to maintain engagement between the reusable and disposable components when the reusable and disposable components are engaged, and an electrical mating feature is configured to transmit electrical energy between the disposable and reusable components when the disposable and reusable components are engaged. All mechanical motion resulting from operation of the mechanical actuator may be contained within the disposable component.
