Description

A kind of endoscope sleeve pipe

Technical field

This utility model relates to medical apparatus, specifically is a kind of endoscope's sleeve pipe that is applicable to that anal and intestinal disease diagnosis and treatment are used.

Background technology

Anus and intestine endoscope therapeutic apparatus has very important effect in the diagnosis of anal and intestinal disease and treatment, and as endoscope's sleeve pipe of anus and intestine endoscope therapeutic apparatus important component part, also there is very big influence in its structure to the inspection and the therapeutic effect of therapeutic instrument.The endoscope's sleeve pipe that uses in hospital at present has multiple structure, a kind of endoscope sleeve pipe is wherein arranged, as China Patent No. is the disclosed anus and intestine endoscope therapeutic apparatus of ZL200610043331.9, its architectural feature is that endoscopic catheters, treatment conduit pass in the anorectal pipe simultaneously, and manifest light source and camera lens and treatment catheter port at the one end, endoscopic catheters is drawn with main frame at the other end of anorectal pipe and is connected, display screen is housed on the main frame, the treatment conduit is drawn to form at the other end of anorectal pipe and is closed reducing, and the end that the treatment conduit is drawn at the anorectal pipe also is provided with airway.The telescopic airway of the endoscope of this structure is connected with the treatment conduit, inflate in rectum by airway earlier before the operation, and when adopting operating forceps or scalpel from the treatment conduit, to stretch into internal rectum focus is undergone surgery, gas and hydrops might be discharged from the treatment conduit, have influenced the carrying out of operation.Simultaneously, because the camera lens outer wall of endoscopic catheters in use can touch intrarectal liquid or solid kenosis, made dirty easily and have influence on and observe and therapeutic effect, when needs are cleared up, retrieve and wipe camera lens, seem extremely inconvenient like this.

Summary of the invention

The purpose of this utility model is at above-mentioned existing problems and deficiency, but the definition that provides a kind of shunting to fill aerofluxus body and liquid, assurance sleeve pipe camera lens improves and checks and endoscope's sleeve pipe of therapeutic effect.

The technical solution of the utility model is achieved in that a kind of endoscope sleeve pipe, comprise the sleeve pipe that can place endoscope probe, be arranged on the camera lens of sleeve pipe front end and be arranged on the flange ring of sleeve pipe rear end, be provided with the treatment passage in its middle sleeve, also be provided with the drain passage and the air guide channel that connect the camera lens outer wall in the sleeve pipe, drain passage and air guide channel front end water jet and gas outlet are over against the outer wall setting of camera lens.For improving cleaning performance, sleeve pipe camera lens outer wall is provided with the camera lens outer wall over against this inclination for the inclined-plane of inclination, water jet and gas outlet.

For making things convenient for the production of product, the front end inner chamber of drain passage and air guide channel is nested with sprinkler head respectively, and water jet and gas outlet are arranged on the sprinkler head.The camera lens rear end is provided with cannelure, and the sleeve pipe front end sleeve places cannelure and connects as one by fluid sealant.

Above-mentioned flange ring be provided with can with the treatment passage, air guide channel and drain channel connection treatment channel connector, air guide channel joint and drain channel connector.

For avoiding cross infection, flange ring is provided with easy switch out spare.The direct easy switch out spare of switch out after the disposable use of endoscope's sleeve pipe makes it break away from hand-held handle, throws away endoscope's sleeve pipe again.

This utility model is owing to adopted drain passage and the air guide channel that is provided with perforation camera lens outer wall in the sleeve pipe, drain passage and air guide channel front end water jet and gas outlet are over against the version of the outer wall setting of camera lens, when endoscope's sleeve pipe in use camera lens made dirty influence when observing, can clean the camera lens outer wall by the water of drain passage water jet ejection, keep the clean of camera lens, made things convenient for and checked and treatment, must not take out sleeve pipe and wipe camera lens, the health when having guaranteed operation and improved work efficiency.Simultaneously, air guide channel front end gas outlet is provided with the outer wall over against camera lens, can be used as on the basis of rectum inner chamber inflation with the expansion range of observation at it, and the gas that ejects can further improve the cleaning effect of camera lens outer wall.This utility model can disposablely use, and can avoid the problem of cross infection to take place.The definition that can keep camera lens during use can effectively improve the accuracy of diagnosis and the effect of treatment, has also made things convenient for medical worker's operation simultaneously.

Below in conjunction with accompanying drawing this utility model is further described.
