ABSTRACT:
The control cable for a rockable forceps elevator of a side-looking endoscope has an elastomeric sleeve covering the exterior part of the cable from the endoscope head to the connection of the cable with the elevator. Seals are effected between the sleeve and the wall and between the sleeve and the distal end of the cable with nipples of rigid tubing and an epoxy or elastomeric sealing material. A fine wire coil spring is disposed over the cable within the sleeve and is constrained between the nipples. The coil spring prevents abrasion of the sleeve from the cable and also prevents collapse of the sleeve.
