Description
Technical field
The present invention relates to medical instruments field, relate in particular to a kind of conduit extractor.
Background technology
In the endoscopic surgery for nose bile duct of passing through, nose ductus pancreaticus surgical drainage; To change with the nose bile duct (nose ductus pancreaticus) that scope is drawn from the oral cavity when drawing by via intranasal application; The stomach tube that needs to insert from nasal cavity or the front end trans-oral of catheter are drawn, and outside the oral cavity, nose bile duct (nose ductus pancreaticus) are inserted in stomach tube or catheter.When stomach tube or catheter trans-oral are drawn at present; Be under non-direct-view situation, adopt finger directly to pluck out or press from both sides out with tweezers, not only conduit takes out trouble; And can cause major injury to oral cavity and pharynx rear wall, operator's possibility polluted in addition by operator's oral secretion.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming and provide a kind of use simple and direct, safety, patient's no pain, conduit take out and are easy to per os conduit extractor.
The object of the invention and solve its technical problem underlying and adopt following technical scheme to realize:
Per os conduit extractor of the present invention comprises sleeve, pull bar, gets pipe ring, and wherein: getting pipe ring is the soft ring that is fixed on the pull bar termination, and sleeve set is on pull bar.
Above-mentioned per os conduit extractor, wherein: getting pipe ring is metal or plastic hoop.
Above-mentioned per os conduit extractor, wherein: the drag link end tail is provided with handle.
Above-mentioned per os conduit extractor, wherein: sleeve is provided with handle.
The present invention compared with prior art; Have tangible advantage and beneficial effect, can be known by above technical scheme, getting pipe ring is Collapsible metal or plastic hoop; So that get pipe ring when not using; Can be loaded in the sleeve with drag link sleeve, it just progressively is launched into ring-type in the oral cavity, can not cause discomfort to the patient when guaranteeing that it gets into oral cavity.To get pipe ring and be fixed on the pull bar termination, make that through the push-and-pull pull bar getting pipe ring acts freely, easy to use.During use per os conduit extractor front end is placed in the oral cavity, pull bar pushes away forward along sleeve, discharges to get pipe ring; Get the pipe ring automatic circlewise pharynx rear wall that arrives this moment; When stomach tube or catheter via intranasal application were inserted, stomach tube or catheter front end then passed the entering esophagus by getting pipe ring, when stomach tube or catheter need take out; Pull bar retracts, and gets pipe ring and regain to get into sleeve and stomach tube that entangles or catheter front end are taken out of outside the oral cavity.The invention enables conduit to take out easily, and can not damage oral cavity and pharynx rear wall, patient's no pain uses simple and direct, safety and can avoid by operator's oral secretion pollution operator.
