Abstract:
1. A sheath system for selectively covering a distal end of an electrocautery blade, wherein the electrocautery blade is adapted for connection to an electrosurgical device and capable of transmitting electrosurgical energy, the sheath system comprising: a hub including a body portion defining a lumen therethrough; a sheath including a body portion defining a lumen therethrough, the lumen of the sheath being configured and dimensioned to operatively receive an electrocautery blade therein, the sheath being 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; and a collar configured and dimensioned to support the electrocautery blade, wherein each of a distal end and a proximal end of the electrocautery blade extends from a respective distal and proximal end of the collar, wherein at least a portion of the collar is rotatably supported in the body portion of the hub, and wherein a portion of the collar is disposed in the lumen of the sheath.
