Electrode with rotatably deployable sheath
First Claim
1. 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.

Abstract
A sheath system for selectively covering a distal end of an electrocautery blade is provided. The sheath system includes a hub having a body portion defining a lumen therethrough and a sheath having a body portion defining a lumen therethrough. The lumen of the sheath is configured and dimensioned to operatively receive an electrocautery blade therein. The sheath is translatably associated with the hub such that rotation of the hub in a first direction results in axial movement of the sheath in a first direction to expose a distal end of the electrocautery blade and rotation of the hub in a second direction, opposite to the first direction, results in axial movement of the sheath in a second direction to cover the distal end of the electrocautery blade. The hub and the sheath may be concentric with one another.

14. A sheath system configured to selectively cover an electrocautery blade adapted to connect to an electrosurgical device, the sheath system comprising:
-
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 adapted to be axially aligned with each other and adapted to be aligned with a longitudinal axis of a housing of the electrosurgical device when the electrocautery blade is connected to the electrosurgical device such that rotation of the hub results in axial movement of the sheath to one of expose and cover the distal end of the electrocautery blade. - View Dependent Claims (15, 16, 17, 18, 19, 20)
