Embodiment Construction

[0024] FIG. 1 is a schematic diagram of a system 20 for performing an endoscopic procedure according to an embodiment of the present invention. System 20 includes an endoscope 22 having a working path 24 therethrough. Pathway 24 travels through endoscope 22 from a proximal port 32 generally located at or near a handle 30 of the endoscope to a distal port 33 located at the distal end of the endoscope. Endoscopic instrument 26 traverses path 24 to reach a region of the patient's body proximate the distal end of the endoscope. Typically, endoscopic instrument 26 includes an elongated shaft 27 with a working element 28 at its distal end, as is known in the art. In the example shown in FIG. 1 , working element 28 includes biopsy forceps that are operated to obtain a tissue sample within a patient near distal port 33 . Alternatively or additionally, pathway 24 may be used to apply suction through distal port 33, or to apply liquid or gas to an area outside of the distal port, also...

Abstract

A device for covering an endoscopic instrument (26) is disclosed, comprising a covering assembly (34) having a sleeve dispenser (40) and a port adapter (46) that interfaces with an endoscopic working path Proximal port (32) of (24) cooperates to allow endoscopic instrument (24) to be advanced through the sheath assembly and into the working path. A flexible sleeve (50) housed in the sheath assembly includes a distal end (51) fixed to the sleeve dispenser and a proximal end (53) configured to release endoscopic instruments from The working path engages the endoscopic implement as it retracts, causing the sleeve to protrude from the dispenser in a proximal direction to encase the endoscopic implement.

Description

technical field [0001] The present invention generally relates to the field of endoscopes, and in particular to a disposable sleeve that covers endoscopic instruments when the endoscopic instruments are withdrawn from the body passage. Background technique [0002] It is known in the art to cover endoscopes with a disposable sleeve (also called a sleeve). Flexible endoscopes such as colonoscopes have the great disadvantage of being difficult to clean and disinfect thoroughly, which may lead to cross-infection between patients. This problem can be avoided by covering the endoscope with a single-use sleeve, which is discarded after use. [0003] Endoscopes typically have a working path that extends from a proximal port located outside the body to a distal port located at the distal end of the endoscope. When the distal end of the endoscope is inserted into the body, the working path may be used, inter alia, for passing medical instruments through the distal end of the endosc...
