发明名称 Endoscopic surgical instrument with ability to selectively remove different tissue with mechanical and electrical energy
摘要 Surgical instruments which have multiple functions used in performing endoscopic surgeries, including arthroscopic surgery. The surgical instrument includes a mechanical cutting portion, such as a rotary blade or burr, and an electronic cutting and/or cauterizing portion comprising an electronic surgical device which operates in bipolar mode. This solves the problem of having to constantly remove and insert various surgical instruments into the surgery site in order to remove different kinds of tissues and at different rates and in different manners. A rotary burr works best to remove hard tissues, such as bone, while the bipolar device can be used to cut or ablate soft tissues and/or cauterize tissue, including blood vessels. Alternatively, the mechanical cutting portion may include a rotary blade, which works best for removing soft tissues.
