Description

ABSTRACT:
An improved electrosurgical instrument is disclosed and claims which includes a reusable electrode shaft, a disposable tip and a novel, insulated coupling for removably connecting the disposable tip to the electrode shaft. The present invention provides several advantages and features. The coupling provides ease in connecting the disposable tip to the reusable electrode shaft in an operating room environment. Once the tip is connected to the shaft, the coupling ensures a rigid and secure connection between the tip and the shaft, such that the coupled tip/shaft assembly feels to the surgeon like a single, unitary instrument. In addition, the coupling ensures a good electrical connection between the tip and the shaft, prevents the tip from inadvertently or accidentally becoming separated from the reusable electrode shaft, and maintains the position of the tip relative to the shaft by preventing the tip from rotating relative to the holder. The coupling also includes an insulating sheath that eliminates any conduction paths between the patient and the electrosurgical instrument other than the surgical tip.
