Suture passer devices and methods of using the devices having one or more protective interlocks preventing or limiting operation of the suture passer when deployment of the needle may damage the apparatus or harm the patient. For example, described herein are suture passer devices that include an interlock preventing deployment of the tissue penetrator (needle) when the jaws are not clamped onto a tissue. Also described herein are interlocks preventing retraction of a jaw axially until the needle is retracted.

The present teachings provide for a device with a membrane and an underlying switch, an underlying switch actuator, or both that has a unique tactile pattern that is felt through the membrane when the membrane is aligned with the switch, switch actuator, or both, corresponding to the electrical state of the device. The membrane, the switch, the switch actuator or a combination thereof can be repositioned from a first position to a second position so that a different tactile feel is present through the membrane corresponding to a second electrical state.

A surgical rongeur includes a lower shaft that defines a floor including a trap door, the lower shaft terminates in a static footplate. An upper shaft is slidably coupled to a top surface of the lower shaft, the upper shaft terminates in a cutting blade. An elongated member is slidably coupled along the floor of the lower shaft and terminates in a sliding footplate. A primary trigger is coupled to the upper shaft, where actuation of the primary trigger is configured to alternately move the cutting blade between an open position and a closed position. A secondary trigger is coupled to the elongated member, where actuation of the secondary trigger, while the cutting blade is in the closed position, is configured to retract the sliding footplate from the static footplate into one of a plurality of positions.

The present disclosure is directed toward an electrosurgical apparatus including an electrosurgical generator that may be coupled to an electrosurgical applicator. In one aspect of the present disclosure, a controller of the electrosurgical generator is configured to execute a dynamic leakage current compensation algorithm or function to compensate for the leakage current of an electrosurgical applicator and accompanying cable coupling the electrosurgical applicator to electrosurgical generator. In another aspect of the present disclosure, the controller of the electrosurgical generator is configured to execute a dynamic radio frequency modulation algorithm or function to dynamically control the crest factor of the output waveform of the electrosurgical generator based on the measured impedance across an active and return terminal of the electrosurgical generator.
