A medical instrument is disclosed. The medical instrument includes at least one electrical contact element, a battery, a radio frequency (RF) generation circuit coupled to and operated by the battery and operable to generate an RF drive signal and to provide the RF drive signal to the at least one electrical contact, and a battery discharge circuit coupled to the battery. A processor is coupled to the battery discharge circuit and a memory is coupled to the processor. The memory stores machine executable instructions that when executed cause the processor to monitor activation of the RF generation circuit and disable the RF generation circuit when the RF drive signal is fired a predetermined number of times. The medical instrument may include an activation switch and/or a disposal switch supported by the housing.

Battery powered surgical instrument

A medical instrument is disclosed. The medical instrument includes a housing and a handle for gripping by a user, an end effector coupled to the handle and having at least one electrical contact, a battery, and a radio frequency (RF) generation circuit coupled to and operated by the battery. The RF generation circuit is operable to generate an RF drive signal and to provide the RF drive signal to the at least one electrical contact, wherein the RF generation circuit is supported by the housing. The RF generation circuit includes a resonant circuit that includes at least one inductive element constructed of litz wire.

A medical instrument is disclosed. The medical instrument includes a housing, a control lever rotatably coupled to the housing, at least one electrical contact, a radio frequency (RF) generation circuit coupled to and operated by the battery and operable to generate an RF drive signal and to provide the RF drive signal to the at least one electrical contact and an initialization clip coupled to housing and the control lever to prevent operation of the RF generation circuit and movement of the control lever.

An ophthalmic illumination system includes planar shapes serially positioned in a path for a collimated beam, along an optical axis. The shapes are rotationally symmetric with one another relative to the optical axis. Each shape has a central rotational axis intersecting the optical axis. Generally wedge-shaped segments of the shapes are spaced apart around and converge at the optical axis to provide generally wedge-shaped apertures to the beam between the segments. The shapes are rotatable on the rotational axes along the optical axis to assume a plurality of configurations to vary intensity of the beam. The beam can fill spatial modes at substantially all radii of the optical fiber entrance pupil.
