Definitions

  • the present invention relates to irrigation devices useful in endoscopic procedures.
  • a clear field of vision is desirable at all times when performing endoscopy or carry ig out endoscopic procedures in the gut. Due to the nature of endoscopic procedures, the view may be obscured at any time during an endoscopic procedure despite measures taken pre operatively, by food, faeces, blood or secretions.
  • the lens of the camera of the endoscope may be cleared using the normal washing device incorporated in all endoscopes. This water jet is not usually powerful enou- ⁇ h to clear the operating field beyond the lens. To do this, an endoscopist will usually use a lar-ge syringe filled with irrigating or tap water, and inject the contents down the operating channel of the endoscope.
  • the invention includes apparatus for use with endoscopic apparatus, said apparatus comprising or including defining with a housing or housing assembly (""housing"). - -
  • a first passageway linking first and second ports of the housing such first passageway being substantially straight
  • a second passageway linking a third port to said first passageway and
  • endoscopic apparatus e.g. adapted directly or indirectly e.g. with a separate linkage
  • the valving arrangement requires intervention from a biased closed condition in order to hold an open condition.
  • a female/female connection member can be used on said second port.
  • the invention is an endoscopic assembly comprising or including apparatus as a fluid supply and/or a gas supply connecting to said third port, and an endoscope having an operating channel connecting (directly or indirectly) to said second port, and (optionally) a closure for said first port and/or apparatus to operate through said first passageway into said operating channel.
  • an endoscopic assembly comprising or including apparatus comprising or including defining with a housing or housing assembly ("housing") a first passageway" linking first and second ports of the housing, such first passageway being substantially straight, and a second passageway linking a third port to said first passageway a fluid and/or gas supply connecting to said third port, an endoscope having an operating channel connecting (directly or indirectly) to said second port, and (optionally) a closure for said first port and/or apparatus to operate through said first passageway into said operating channel, wherein a valving arrangement of the housing and/or the connecting fluid or gas supply can, in use, allow on demand fluid and/or gas supply via said third port and second passageway to the second port and thus into said operating channel.
  • the invention is a junction assembly associable with an endoscope whereby a controllable irrigation fluid or insufflation gas flow can enter an operating channel of the assembly and, in use, that of the associated endoscope without a need to open the entrance to said operating channel of the assembly or to remove operating or functional apparatus associated thereto or thereinto.

  • Irrigation fluid from a bag placed inside a pressure infusor or pressurised container is passed via a plastic tube which may be a standard giving set to a Luer lock on the valve housing.
  • a push button or lever control of the valving arrangement allows the saline to flow under pressure down the operating channel.
  • irrigating fluid may be substituted by carbon dioxide gas from a low pressure system in the same way, to inflate the bowel with carbon dioxide as an alternative to room air.
  • On top of the valve is a port that allows instruments e.g.
  • any normal endoscopic instrument to be passed in the usual manner, with the device still attached to the endoscope.
  • This device allows pressurised irrigating fluid to pass down the operating channel of any endoscope to clear away blood/food/faecal residue. It is operated by the endoscopist, and avoids the need for syringes, thus freeing up a member of staff who would otherwise need to fill them for the endoscopist.
  • instruments can be passed down the operating channel of the endoscope without removing the device. Where variceal banding equipment is used, it may be attached with the device in place, and saline can be passed alongside the thread that is passed down the operating channel.
  • This device allows large quantities of fluid to be passed down the endoscope at once, compared to syringes, which can pass no more than 50ml at a time. Instillation of warm water is shown to be a useful and safe method of relieving spasm during colonoscopy, which can easily be done by warming the bag of saline prior to attachment to the device. Instillation of larger volumes of fluid (200 - 1000ml) has been used in some centres to make colonoscopy easier and more comfortable, which is facilitated once again using this device. This device also allows the passage of C02 down the operating channel of the endoscope where it is preferred to room air, to prevent excess wind trapping and discomfort after endoscopic procedures.
