Abstract
This invention relates to a surgical instrument. Specifically, a surgical instrument is disclosed which dispenses incising, transecting, or tissue treating energy to a body site or part undergoing an operation or treatment where energy is discharged from a conduit to effect the treatment. The disclosed instrument is inserted to an operative site that effectively rules out proximal manipulation of the instrument. Therefore, proximal insertion with subsequent distal manipulation excluding proximal side-to-side or up and down manipulation is disclosed. The disclosure further includes a deployable shield and is ideal for operative engagement to surgical sites on the body such as the carpal tunnel, tarsal tunnel, the wrist, temporomandibular joint, or scar tissue capsules forming around implants of the breast.
