A surgical instrument comprising a jaw assembly is disclosed. The surgical instrument further comprises a motor-driven drive system configured to open the jaw assembly. The surgical instrument also comprises a control system configured to control the drive system and, also, control a power supply system configured to supply electrical power to electrodes defined in the outer surface, or outer surfaces, of the jaw assembly. In use, the surgical instrument can be used to apply mechanical energy and electrical energy to the tissue of a patient at the same time, or at different times. In certain embodiments, the user controls when the mechanical and electrical energies are applied. In some embodiments, the control system controls when the mechanical and electrical energies are applied.

Methods and related apparatus for real-time process monitoring during laser-based refractive index modification of an intraocular lens. During in situ laser treatment of the IOL to modify the refractive index of the IOL material, a signal from the IOL is measured to determine the processing effect of the refractive index modification, and based on the determination, to adjust the laser system parameters to achieve intended processing result. The signal measured from the IOL may be a fluorescent signal induced by the treatment laser, a fluorescent signal induced by an external illumination source, a temporary photodarkening effect, a color change, or a refractive index change directly measured by phase stabilized OCT.

A suction or other component of an endoscope system may be cycled on and off or otherwise controlled without requiring direct user input, such as automatically or semi-automatically using a current or historical state of a laser generator, a blurriness or other information from an image of the working area, a count of fragments of a calculi stone, an intraoperative pressure, an intraoperative temperature, or one or more other characteristics of the laser generator or the targeted calculi stone.

A laser can be controlled based on different tissue compositions, such as in real time. After a first time period, a first composition of a in vivo target site can be identified. Based on the first composition, a plurality of lasers can be controlled to emit light at a first wavelength where controlling includes activating a first combination of the plurality of lasers. After a second time period, a second composition of the in vivo target site different from the first composition can be identified. Based on the second composition, a plurality of lasers can be controlled to emit light at a second wavelength, such as can include activating a second combination of the plurality of lasers. The first combination of the plurality of lasers can be different from the second combination of the plurality of lasers.

A method for determining a characteristic of material at a target is provided. A target is illuminated with a pulsed light source. A fluorescence signal from the target when the pulsed light source is an “off” state is then sensed. Based on analysis of the fluorescence signal, a characteristic of material at the target is identified. A device can then be controlled based on the identified characteristic of the material at the target.

A surgical system is disclosed including an end effector, a control circuit, a closure member, and a firing member. The end effector includes a first jaw, a second jaw, and an electrode. The first jaw is rotatable relative to the second jaw between an open position and a close position to capture tissue therebetween. The electrode is configured to conduct a sub-therapeutic RF current to the tissue. The control circuit is operably coupled to the electrode. The control circuit is configured to measure impedance of the tissue over time based on the sub-therapeutic RF current. The closure member is configured to move the first jaw towards the second jaw at a closure rate based on the impedance of the tissue. The firing member is configured to move within the end effectors towards a fired position at a firing rate based on the impedance of the tissue.

A platform device for material excision or removal from vascular structures for either handheld or stereotactic table or robotics platform use may comprise a work element or elements configured to selectively open and close at least one articulable beak or scoopula configured to penetrate and remove intra-vascular materials or obstructions, or follow a central lumen of another device or over a wire in a longitudinal direction. Flush and vacuum tissue transport mechanisms may be incorporated as well as single or multiple arrays of image guidance elements, directional elements, ablation elements and other interventional assistance elements. A single tube or an inner sheath and an outer sheath which may be co-axially disposed relative to a work element may be configured to actuate a beak or beaks or scoopulas and provisions for simultaneous or differential beak or scoopula closing under their differential rotation may be incorporated.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.
