    摘要: The invention provides a handpiece for controlling movement of an electrosurgical device along a lumen of a catheter. The handpiece comprises a first section having a connector for connecting a distal end of the handpiece to an instrument port of a surgical scoping device. The handpiece further comprises a second section connected to the first section and movable along a length of the first section, the second section having a holder for holding a proximal end of the catheter, whereby relative movement between the second section and first section is arranged to control a length of catheter that extends out of a distal end of the handpiece. The handpiece also comprises a third section connected to the second section and movable along a length the second section, the third section having a coaxial connector arranged to receive a proximal end of a coaxial cable that is conveyed within the lumen of the catheter, whereby relative movement between the third section and second section is arranged to control a relative position of the coaxial cable within the catheter. The handpiece of the invention enables a length of the catheter to be adjusted independently of the position of the electrosurgical device in the catheter. In this manner, the length of the catheter may be adjusted so that it fits within the instrument channel of the surgical scoping device.
