A surgical instrument includes an end effector assembly including first and second grasping components each defining a tissue-contacting portion. One or both of the grasping components is movable relative to the other to a closed position wherein the tissue-contacting portions cooperate to define a grasping area therebetween. One or both of the grasping components is configured to apply energy from the tissue-contacting portion thereof to tissue disposed within the grasping area to treat tissue. The tissue-contacting portion of the first grasping component defines a first opening disposed within the grasping area and in communication with a first lumen defined at least partially through the first grasping component. The first lumen is adapted to connect to a source of vacuum to enable aspiration through the first opening.

The insulation is configured to fully electrically isolate the outer cannula tube and the inner cannula tube in relation to one another.

Forward-Looking Precision Imaging Surgical Probe

A precision forward-looking image-guided diagnostic and therapeutic surgical probe and needle insert for microsurgery in support of imagery, neurology, neurosurgical procedures, and ophthalmic surgical applications comprising an introducer needle (stylet), a fiber carrier, a therapeutic conduit, and a spirographic method for scanning a target and associated algorithms to create and render a reconstructed image for display to a physician in real-time or near real-time. The probe implements Optical Coherence Tomography (OCT) to provide high-resolution extended imagery of an intended therapeutic or target tissue. A separate therapeutic conduit provides surgical access for therapeutic devices such as a cutting or ablation laser, an RF electrode for locally heating tissue, a lumen for local injection of neurolytics/paralytics, placement of electrodes for neuromodulation, and deployment of a micro-endoscopic imaging tool. A third working channel supports the delivery of neurolytic and other fluids.
