ABSTRACT:
A therapeutic or diagnostic accessory and containment system for use with a flexible or rigid endoscope during an endoscopic procedure. The system includes an accessory and a containment enclosure, wherein the accessory has an elongated, flexible, and axially-rigid shaft shaped to fit into the endoscope's biopsy channel and a tool connected to the shaft's distal end. The enclosure is adapted to contain at least a major portion of the shaft is remote from the endoscope and has at least one aperture through which the distal end of the shaft extends. An instrument deploying mechanism connected to the enclosure and to the shaft has a withdrawing mechanism that withdraws the shape into the enclosure through the aperture. A control mechanism for controlling the tool is attached to the proximal end of the shaft. The accessory can be disposable or reusable and is used in conjunction with an endoscope to perform an endoscopic procedure. The method includes inserting the shaft into a patient through the endoscope's insertion tube, performing a predetermining procedure, withdrawing the shaft and tool from the insertion tube, and immediately containing the shaft within the disposable enclosure. Thereafter, the accessory may be disposed of or cleaned, disinfected, and/or sterilized.
