Description
Technical field
This utility model relates to a kind of medical apparatus, specifically a kind of gastroscope of replaceable washer jet.
Background technology
At present, the gastroscope for digestive tract disease inspection and treatment forms primarily of gastroscope tube, operating portion, and the end of gastroscope tube arranges illuminating lamp and photographic head.Some patient causes food retention in gastrointestinal tract because of disease reason, can not clean out by the method for inserting stomach tube and carry out gastrointestinal decompression and gastric lavage, and when doing gastroscopy, food debris pollutes illuminating lamp and photographic head, thus impact is to the observation of diseased region and treatment.Chinese patent 2012205713425 discloses " a kind of gastroscope ", feed liquor mozzle and fluid mozzle are set in gastroscope tube, the flushing liquor utilizing feed liquor mozzle to input rinses the inside of stomach, and is derived by flushing liquor by fluid mozzle, avoids food debris to pollute illuminating lamp and photographic head.But in actual use, because the mouth of pipe of feed liquor mozzle and fluid mozzle is arranged in parallel, and all can not directly rinse illuminating lamp and photographic head, flushing liquor flushing coat of the stomach on the contrary easy being swept away by food on coat of the stomach pollutes illuminating lamp and photographic head.
Summary of the invention
The purpose of this utility model is to provide the gastroscope with washer jet that a kind of structure is simple, easy to operate, have cleaning illuminating lamp and camera function.
The technical scheme that this utility model adopts for technical solution problem is:
The gastroscope of replaceable washer jet described in the utility model comprises operating portion, be arranged on the gastroscope tube of operating portion lower end, water inlet pipe and outlet pipe is provided with in gastroscope tube, water inlet pipe and outlet pipe extend to the end of gastroscope tube, the end of gastroscope tube is provided with illuminating lamp and photographic head, the upper end sidewall of described gastroscope tube is provided with side pipe, described side pipe establishes the double lumen tube of two passages in being, two passages in side pipe are communicated with water inlet pipe and outlet pipe respectively, the end of described water inlet pipe is provided with nozzle, the upper end of described nozzle is threaded connection the pipe at water inlet pipe mouth of pipe place, the lower end of described nozzle is the hemispherical housing with spray orifice, upper end and the pipe of described hemispherical housing are connected in one, the axis of multiple spray orifice is arranged in the radius of hemispherical housing.
The cylindrical parts of nozzle and the junction of hemispherical housing parts are provided with annular boss.
After adopting technique scheme, the flushing liquor that water inlet pipe can input by the nozzle of this gastroscope end changes that direction is spherical in shape spreads to surrounding, also directly rinse illuminating lamp and photographic head while the flushing liquor flushing coat of the stomach of diffusion, structure is simple, easy to operate, and developing result is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is the sectional structure schematic diagram of gastroscope tube end.
Detailed description of the invention
As shown in Figure 1, the gastroscope of replaceable washer jet described in the utility model comprises operating portion 1, be arranged on the gastroscope tube 2 of operating portion 1 lower end, water inlet pipe 21 and outlet pipe 22 is provided with in gastroscope tube 2, water inlet pipe 21 and outlet pipe 22 extend to the end of gastroscope tube 2, the end of gastroscope tube 2 is provided with illuminating lamp 6 and photographic head 7, the upper end sidewall of described gastroscope tube 2 is provided with side pipe 3, described side pipe 3 establishes the double lumen tube of two passages in being, two passages in side pipe 3 are communicated with water inlet pipe 21 and outlet pipe 22 respectively, the end of described water inlet pipe 21 is provided with nozzle 8, the upper end of described nozzle 8 is threaded connection the pipe at water inlet pipe 21 mouth of pipe place, the lower end of described nozzle 8 is the hemispherical housing with spray orifice 9, upper end and the pipe of described hemispherical housing are connected in one, the axis of multiple spray orifice 9 is arranged in the radius of hemispherical housing.
The cylindrical parts of nozzle 8 and the junction of hemispherical housing parts are provided with annular boss 7.This annular boss 7 can limit the length that cylindrical parts puts in water inlet pipe 21 mouth of pipe, makes hemispherical housing parts keep exposing.
In gastroscopy procedures, as found, illuminating lamp or photographic head are polluted by food debris, can input flushing liquor by water inlet pipe 21, and flushing liquor is spread to surrounding by spray orifice 9, rinse the illuminating lamp and the photographic head that are positioned at gastroscope tube end, derive external with overflush fluid by outlet pipe 22.
