Patent ID: 8460289

Claim:
An electrosurgical system, comprising: an electrosurgical device including a housing having a longitudinal axis defined therethrough; an electrocautery blade assembly configured for selective, removable connection to the electrosurgical device, the electrocautery blade assembly including an electrocautery blade including a proximal end supportable in the housing of the electrosurgical device and a distal end extending distally from the housing; a sheath system, including: a hub including a body portion defining a lumen therethrough; a sheath translatably associated with the hub and including a body portion defining a lumen therethrough; and a collar configured to support the electrocautery blade therein, wherein a central axis of the collar, a central axis of the lumen of the hub, a central axis of the lumen of the sheath, and a central axis of the electrocautery blade are axially aligned with each other and the longitudinal axis of the housing such that rotation of the hub results in axial movement of the sheath to expose or cover the distal end of the electrocautery blade.
