Interface Joint

Abstract: various embodiments provide an interface joint for interconnecting an electrosurgical generator, a fluid supply, and an electrosurgical instrument. the interface joint comprises a housing having: an electrical inlet for receiving radiofrequency (rf) electromagnetic (em) energy and/or microwave frequency em energy from the electrosurgical generator; a fluid inlet for receiving fluid from the fluid supply; and, an outlet. the interface joint also comprises a single cable assembly for connecting the outlet to an instrument tip of the electrosurgical instrument. the single cable assembly comprises: a flexible shaft having: a coaxial cable that is connected to the electrical inlet; and a fluid channel that is in fluid communication with the fluid inlet. the housing includes a first portion and a second portion, the second portion being attached to the single cable assembly such that rotation of the second portion effects rotation of the single cable assembly; and the first portion being rotatable relative to the second portion. the first portion includes a first inlet, and the second portion includes a second inlet, wherein the first inlet is one of the fluid inlet or electrical inlet, and the second inlet is the other of the fluid inlet or electrical inlet.
