Embodiment Construction

[0033] FIG. 1 is a schematic diagram of an embodiment of the invention, indicated by reference numeral 10 . This embodiment refers to the combination of surgical instrument 12 and sheath assembly 14 . The surgical instrument includes an elongated shaft 16, which may be made of metallic material or plastic. The rear end of the shaft is provided with a thumb ring for operating the instrument, while its distal end is provided with a working element 20 for performing the surgical procedure. The working element shown in Figure 1 is a biopsy forceps operable to remove a tissue sample from within a patient's body. However, it should be understood that this is merely an example and the working element may be of any other kind that may be required during the procedure, such as a polyp snare or the like.

[0034] The structure of the sheath assembly will now be explained in more detail with reference to Figures 2, 2a and 2b. The jacket assembly consists of several separable parts who...

Abstract

Apparatus for sheathing an endoscopic tool is described. The apparatus is suitable for sheathing the tool when it is displaced in a proximal direction from a working channel of an endoscope. The apparatus comprises a sheathing assembly, which is attachable to a proximal port of the endoscope and to the endoscopic tool. Within the sheathing assembly is deployed a folded, flexible sleeve adapted to unfold from the assembly when the tool is retracted in the proximal direction from the working channel. The sheathing assembly is designed to allow displacement of the tool through the sheathing assembly in a distal direction and simultaneous retraction of the tool together with the sheathing assembly in the proximal direction.

Description

technical field [0001] The present invention relates to endoscopy, and in particular to endoscopic instruments provided with a sleeve capable of covering said endoscopic instrument during withdrawal of said instrument from a body passage. Background technique [0002] The use of disposable sleeves (also referred to as sheaths) to cover endoscopes is known in the art. Flexible endoscopes, such as colonoscopes, are very difficult to clean and fully sterilize, leading to cross-contamination issues between patients and between patients and staff. These problems can be partially avoided by covering the endoscope with a single-use sleeve that is discarded after use. [0003] Endoscopes generally have working channels that extend from a proximal port on the outside of the body to a distal port at the distal end of the endoscope. When the distal end of the endoscope is inserted into the body, the working channel can also be used in particular to pass surgical instruments (also ref...
