Abstract

An apparatus includes a conductive cable, a pulley assembly, and an end effector electrically coupled to the conductive cable. The pulley assembly includes an inner body defining a cable pathway, an outer body fixed to the inner body, and a distal cap defining an interior. The end effector includes a distal hook that can deliver therapeutic energy to tissue, and a proximal body fixed relative to the dismal hook. The proximal body defines a conductive wire channel in communication with the cable pathway defined by the inner body. The conductive cable extends though the cable pathway of the inner body and into the conductive wire channel. The proximal body of the end effector defines a first port located within the interior of the distal cap, where the first port extends from an outer surface of the proximal body into the conductive wire channel.

Dependent claims

An apparatus, comprising:

(a) a conductive cable;
(b) a pulley assembly, the pulley assembly comprising:
(i) an inner body defining a cable pathway extending between a proximal end and a distal end,
(ii) an outer body fixedly attached to the inner body, the outer body defining a cable port in communication with the proximal end of the cable pathway, and
(iii) a distal cap defining an interior;
and
(c) an end effector electrically coupled to the conductive cable, comprising:
(i) a distal hook configured to receive therapeutic energy from the conductive cable and deliver the received therapy energy to tissue,
(ii) a proximal body fixed relative to the distal hook, wherein the proximal body defines a conductive wire channel in communication with the distal end of the cable pathway defined by the inner body,
wherein the conductive cable extends through the cable port of the outer body, the cable pathway of the inner body, and into the conductive wire channel,
wherein the proximal body defines a first port located within the interior of the distal cap, wherein the first port extends from an outer surface of the proximal body into the conductive wire channel.
