Definition : Endoscopes designed for removal or resection of tissues and/or for biopsy of lesions. These instruments may include electric cautery and coagulating capabilities or other means for tissue resection. Most of these resectoscopes consist of an outer sheath, a lighting system (e.g., fiberoptic), a wide-angle telescope, electrosurgical wire loops, and a working channel for catheters and other operative devices. They may also include a television camera on the distal tip. Dedicated resectoscopes have the appropriate dimensions and characteristics for insertion and operation in the natural canals where they are intended to be used (e.g., urinary tract, female genital tract); other simpler resectoscopes are intended to resect tissues through incisions performed in minimal-access surgery procedures (e.g., wrist).
