Abstract
The present invention provides an endoscopic accessory control system that resides externally of the endoscope. The system comprises the endoscopic accessory with a working end to be placed at the distal end of the endoscope, a control sheath extending proximally external to the endoscope and a control handle joined to the proximal end of the control sheath. The control handle is slidably mounted to the exterior surface of the endoscope shaft and is configured to permit grasping of both the shaft and the handle. With the control handle and endoscope shaft grasped with one hand, the other hand of the user is left free to manipulate the endoscope distal tip controls. Additionally, the external arrangement of the control sheath leaves the working channel of the endoscope free for use of accessories or operations.
