Removable tip for use with electrosurgical devices

Abstract

Disclosed herein are various embodiments of electro surgical devices. In one embodiment, the removable tip includes a first tip member, a second tip member, and an insertion member. The first tip member has a distal end and a proximal end. The second tip member has a distal end and a proximal end where the proximal end of the second tip member is directly coupled to the proximal end of the first tip member. The insertion member is directly coupled with the proximal ends of the first and second tip members, the insertion member for inserting the removable tip within an opening in the electrosurgical tool. Once the insertion member is fully inserted and positioned into the electrosurgical tool, the removable tip is rotatable within the opening in the electrosurgical tool while remaining fully inserted and positioned within the electrosurgical tool.

         10 . The removable tip according to  claim 1 , wherein:
 a portion of the first tip member located between the proximal and distal ends of the first tip member comprises a first separating member; and   a portion of the second tip member located between the proximal and distal ends of the second tip member comprises a second separating member.   
     
     
         11 . The removable tip according to  claim 10 , wherein the distal end of the first tip member is removable at or above the first separating member and the distal end of the second tip member is removable at or above the second separating member. 
     
     
         12 . The removable tip according to  claim 11 , wherein the distal ends of the first and second tip members couple with the first separating member and the second separating member by a snap fit. 
     
     
         13 . An electrosurgical tool, comprising:
 a handheld electrosurgical unit, the handheld electrosurgical unit configured to be connected with an electro surgical wall unit and including at least a first button to activate a cutting mode and a second button to activate a cauterizing mode; and   a removable tip; the removable tip comprising:
 a first tip member having a distal end and a proximal end; 
 a second tip member having a distal end and a proximal end directly coupled to the proximal end of the first tip member; and 
 an insertion member directly coupled with the proximal ends of the first and second tip members, the insertion member for inserting the removable tip within an opening in the handheld electrosurgical unit, wherein once the insertion member is fully inserted and positioned into the handheld electrosurgical unit, the removable tip is rotatable within the opening in the handheld electrosurgical unit while remaining fully inserted and positioned within the handheld electrosurgical unit. 
   
     
     
         14 . The electrosurgical tool according to  claim 13 , wherein:
 when axial pressure is applied to an outer surface of the first and second tip members, the distal ends of the first and second tip members move proximate each other in a closed position; and   when axial pressure is not applied to the outer surface of the first and second tip members, the distal ends of the first and second tip members are separated by a distance from one another in an open position.   
     
     
         15 . The electrosurgical tool according to  claim 13 , further comprising a locking mechanism coupled to the first and second tip members for locking the removable tip in the closed position.
