摘要:
A shaft (14) is provided for a flexible endoscopic instrument, the shaftincluding at leastone flexible section (20) along the length of the shaft, a distal section (19)locateddistally of the flexible section, and a proximal section (18) locatedproximally of theflexible section (20). The distal section (19) includes a connection to ashaft electrode,while the proximal section (18) includes at least one connection forconnecting the shaft(14) to an electrosurgical generator (1). The shaft also includes a bypasslead (26) inelectrical connection with both the distal section (19) and the proximalsection (18).The bypass lead (26) ensures that the distal section (19) and the proximalsection (18)remain at the same potential even if the electrical pathway via the flexiblesection (20)becomes degraded by wear or damage thereto.
