Problems solved by technology

[0006] Unfortunately, the maintenance of endoscopes equipped with the fluid control systems described above is inconvenient and labor intensive, as each tube needs to be connected in turn to the corresponding source of fluid media before being put into use
[0007] Other disadvantages of the control systems in the prior art are the fact that they are not effective in preventing contamination debris from entering the body channel and back into the system

Embodiment Construction

[0016] Referring to FIG. 1 , an endoscopic device, in particular a colonoscopic device 10 , is shown with the main components described below. The device comprises an endoscope having an insertion tube whose proximal end 12 is connected to an operating handle 14 and whose distal end 16 is inserted into and protrudes from a disposable dispenser 18 . Examples of such devices and a general explanation of their structure and function can be found in application PCT / IL03 / 00661, which is hereby incorporated by reference.

[0017] Also, as shown in FIG. 1 , a disposable expandable sleeve covers the distal region of the endoscope. The sleeve portion, which can be seen in FIG. 1 , comprises a front non-expandable portion 15 and a rear pleated portion 17 . The front end portion covers the distal end portion of the endoscope and its head. When the endoscope is advanced in the rectum, the front portion does not expand. The rear portion covers the insertion tube and expands when the sle...

Abstract

A control system for supplying fluid medium to an endoscopic apparatus which comprises an operation handle and an insertion tube provided with an insufflation channel, an irrigation channel and a suction channel extending therealong. The control system is provided with a system control unit with at least one source of a first fluid medium, with a source of a second fluid medium, with a source of vacuum and with a multifunctional connector for bringing the operation handle in fluid and electrical communication with the system control unit. The source of the first fluid medium and the source of the second fluid medium are simultaneously connectable to and disconnectable from the insufflation channel and the irrigation channel.

Description

technical field [0001] The present invention relates generally to the field of endoscopy, and in particular to endoscopic devices for use in colonoscopy procedures in which flexible tubes are inserted into the rectum and colon to examine the interior of the rectum for abnormalities. In particular, the invention relates to a control system for supplying a fluid medium, such as air, water, etc., to an endoscopic device. Background technique [0002] Endoscopes are known which utilize an expandable or inflatable flexible sleeve to advance the endoscope in the colon. [0003] Voloshin (US 6,485,409) discloses an endoscope comprising an endoscopic probe, a curved portion for guiding the probe in the colon (steering unit), an insertion tube and a flexible covering sleeve or sheath closely connected to the probe. set. The curved part of the endoscope is behind the probe. The sleeve is attached to the endoscope in such a way that its folded portion is held...
