Description
Technical field
This utility model belongs to field of medical appliances, is specifically related to a kind of muddy stone attraction defecator that modern medicine is carried out gallbladder, choledochoscope operation, and this defecator cooperates flushing suction instrument to use.
Prior art
Protecting gallbladder in Wicresoft gets in the stone operation, gallbladder mirror or choledochoscope enter the gallbladder intracavity by gallbladder bottom miniature incision, because the diameter of the Inlet and outlet water passage of gallbladder mirror or choledochoscope is between 1mm～3mm, the diameter of some silt sample cholelithiasises and gallbladder mucosa layer calculus is often less than this diameter, when operation suction, these calculus than minor diameter can enter the flushing suction instrument by the passage of gallbladder mirror or choledochoscope and the suction catheter of connection thereof.Operation for collecting these silt sample cholelithiasises and gallbladder mucosa layer calculus, then needs the aspirate to thousands of milliliters to filter after finishing, and process is loaded down with trivial details time-consuming, and in toppling over filtering process, sewage pollutes surrounding easily.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of muddy stone to attract defecator, this defecator can solve Wicresoft quickly and easily and protect effective collection that gallbladder is got silt sample cholelithiasis, gallbladder mucosa layer calculus and small polyps in the stone operation, improves operation efficient.
In order to realize above-mentioned technical purpose, this utility model is realized by following technical scheme:
A kind of muddy stone attracts defecator, comprise the upper shell, the lower house that have center cavity, described upper shell, lower house cooperate together and form a hollow container, described hollow container inside corresponding to the junction of upper shell, lower house be equipped be used for filtering in the middle of screen cloth, the top of described upper shell offers and is used for the interface that links to each other with the exit passageway of gallbladder mirror or choledochoscope, and the bottom of described lower house offers and washes the interface that suction instrument is connected.The internal diameter of described upper shell and lower house is 50～100mm, wall thickness 1～2mm.
In this utility model, described upper shell and lower house are the cylindrical bottle that an end is an opening, the two is connected by the internal and external screw thread that is located at the opening part outer wall, can form a hollow bottle with sealing after the cylindrical bottle of two openings is threaded, and its capacity is 250ml～500ml.
Screen cloth for convenience and in the middle of the firm placement, the inwall of described upper shell and lower house is equipped with a stepped step surface, described in the middle of screen cloth be placed between the two stepped step surfaces.
Screen cloth is that upper end open, lower surface are the cylindrical drum that is provided with filtering net plate in the middle of described, and the outer diameter of described middle screen cloth is identical with the inner diameter of upper shell and lower house.
The filter opening diameter of described filtering net plate is smaller or equal to 1mm, so just the silt particle shape calculus of diameter greater than 1mm can be filtered out, thereby can directly not enter into the flushing suction instrument, simplify filter process once more the aspirate in the flushing suction instrument, simple to operation.
Compared with prior art, the beneficial effects of the utility model are:
Muddy stone of the present utility model attracts the top interface of the upper shell of defecator to be connected by the exhalant canal of pipeline with gallbladder mirror or choledochoscope, the bottom interface of the lower house of defecator can be connected by the interface of pipeline with the flushing suction instrument, protecting gallbladder in execution Wicresoft gets in the process of stone operation, when using negative pressure to draw the liquid in art district, tissue substances such as minor diameter muddy stone in the art district and tiny polyp then can enter defecator by the exhalant canal of scope, under the effect of middle screen cloth, liquid can enter the flushing suction instrument by screen cloth, muddy stone and tiny polyp then are collected among the middle screen cloth, the medical worker can open defecator after operation finishes, make top and the bottom separate, screen cloth in the middle of taking out is collected patient's calculus and polyp sample.By using this utility model, can so that the collection process of calculus polyp sample become simple and easy effectively, and can effectively prevent the sewage pollution medical worker and the surrounding that produce in the operation process.
