  • Publication number: 20230233248
    Abstract: A handpiece for a surgical instrument, having a lumen for the provision of suction or fluids to the surgical instrument, the lumen being formed from at least two concentrically arranged tubes, one of the tubes being formed from metal, and the other of the tubes being formed from an electrically insulating material, the arrangement being such as to prevent electrical charge carried by any fluid within the lumen from leaking to an external surface of the lumen. In one example the at least two concentrically arranged tubes define a tube connector having a distal end and a proximal end, wherein the proximal end is located within a receiving formation in the handpiece and the distal end protrudes outwardly from the handpiece.
