摘要:
A shaft 14 is provided for a flexible endoscopic instrument e.g. electrosurgical, the shaft including at least one flexible section 20 along the length of the shaft, a distal section 19 located distally of the flexible section, and a proximal section 18 located proximally of the flexible section 20. The distal section 19 includes a connection to a shaft electrode, while the proximal section 18 includes at least one connection for connecting the shaft 14 to an electrosurgical generator 1. The shaft also includes a bypass lead 26 in electrical connection with both the distal section 19 and the proximal section 18. The bypass lead 26 ensures that the distal section 19 and the proximal section remain at the same potential even if the electrical pathway via the flexible section 20 becomes degraded by wear or damage thereto.
