An assembly of mains electricity (AC-powered) devices designed to perform arthroscopic shaving (i.e., abrasion, resection, debridement of bone and soft tissue with a blade) and electrosurgical diathermy (i.e., the ablation and coagulation of soft tissue, as well as haemostasis of blood vessels, with an electrosurgical probe) during arthroscopic procedures on a joint. It typically consists of a combination shaver/electrosurgical generator with operational display and software to help provide optimal parameters for the shaver handpiece(s) to operate a variety of burs/blades and electrosurgical probes, tips, and cables. An irrigation system may be included.
