Description
Technical field
This utility model relates to technical field of medical instruments, is a kind of nose bile duct auxiliary device.
Background technology
Clinically, be expert at endoscopic retrograde ERCP (ERCP) time, often need to carry out biliary drainage in bile duct to some patients's indwelling nose bile duct.During indwelling nose bile duct, be first placed in biliary tract in through digestive tract by one end of nose bile duct by oral cavity duodenoscope, the other end is stayed outside oral cavity, then is drawn from nasal cavity by nose bile duct through mouth and nose conversion, to alleviate the uncomfortable degree of patient's indwelling nose bile duct.When the mouth and nose conversion carrying out nose bile duct, common way is: be inserted in oral cavity by a nose tube at one end from nasal cavity, again with hands by its from oral cavity pull-out and with stay extrabuccal nose bile duct and dock, the one end of namely one end of nose bile duct being inserted nose conduit is connected mutually, then tractive is stayed the nose conduit other end outside nasal cavity and is extracted out from nasal cavity by nose conduit, namely nose bile duct goes to nasal cavity with nose conduit by oral cavity and stretches out from nasal cavity, nose bile duct one end is extracted from nose conduit, thus completes mouth and nose transformation process.One end of nose conduit is fingerhold from the taking-up in oral cavity, palmistry is excessive for oral cavity, operating difficulties, needs patient to coordinate and magnifies mouth, operating time has grown the misery that can increase patient, if bite operator's finger when patient can not tolerate and shut up in operation possibly.
Utility model content
In order to solve the problem, the purpose of this utility model is to provide the auxiliary device that a kind of structure is simple, easy to use, conveniently can carry out the conversion of nose bile duct mouth and nose.
To achieve these goals, the technical scheme that this utility model adopts is:
This utility model comprises nose conduit and nose conduit guiding device.Nose conduit is a smooth conduit, and external diameter is little compared with aperture, nostril, is existing hollow tubing conductor, its head circle is blunt, the inner chamber of hollow is used for firmly being connected with nose bile duct, and the outer wall of nose catheter shaft is provided with graduation mark, and graduation mark is about the distance of nostril mouth to pharyngeal cavity to the length of apical head; Nose conduit guiding device is made up of traction fiber, outer tube and seeker, and traction fiber curved shape is by heat-treating profiled, and seeker is globulate by welding traction fiber body, and is connected in one with traction fiber; Outer tube outer wall is provided with graduation mark, and graduation mark is about the distance of nostril mouth to concha nasalis inferior to the length on head end top, and traction fiber penetrates outer tube and moves in outer lumen road.
This Novel nose bile duct auxiliary device, described nose conduit is silica gel material composition.
This Novel nose bile duct auxiliary device, the molding by heat treatment of described traction fiber.
This Novel nose bile duct auxiliary device, described seeker is connected with traction fiber by welding traction fiber body.
This Novel nose bile duct auxiliary device, described traction fiber is nickel-titanium alloy material composition.
This Novel nose bile duct auxiliary device, described outer tube is nylon material composition.
This utility model structure is simple, easy to use, makes that the conversion of the mouth and nose of nose bile duct becomes quick, success rate is high, alleviates the misery of patient and the workload of operator, avoids the risk that existing mouth and nose conversion art may occur.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further illustrated.
Fig. 1 is that the traction fiber of this utility model example 1 and seeker combine schematic diagram;
Fig. 2 is the nose conduit guiding device schematic diagram of this utility model example 1;
Fig. 3 is that the nose conduit of this utility model example 1 loads nasal cavity schematic diagram;
Fig. 4 is the use step schematic diagram of this utility model example 1.
Wherein: 1 is seeker, 2 is traction fiber, and 3 is outer tube, and 3-1 is outer tube graduation mark mark, and 4 is nose conduit, and 4-1 is nose marking catheter.
Detailed description of the invention
Following examples will the utility model is described in further detail by reference to the accompanying drawings
Embodiment 1
This utility model embodiment be provided with nose conduit guiding device and with the use of nose conduit, described nose conduit guiding device is made up of seeker 1, traction fiber 2 and outer tube 3, wherein seeker 1, traction fiber 2 are by being welded and fused, and can move after both welding at outer tube 3 endoporus.
Operational approach of the present utility model is as follows:
1) pull traction fiber 2 to seeker 1 head end to concordant with outer tube one end face;
2) advance nasal cavity to the position of graduation mark 4-1 in nose conduit 4;
3) nose conduit guiding device one end is pushed nose conduit 4, to the position of graduation mark 3-1;
4) nose conduit 4 and outer tube 3 motionless, traction fiber is slowly delivered in the middle part of oral cavity, stops mobile; Advance nose conduit 4 to exposing oral cavity portion;
5) nose conduit guiding device is shifted out completely from nose conduit 4;
6) nose bile duct tip is penetrated nose conduit 4 buccal, advanced, until pass the nasal cavity end of nose conduit 4, withdraw from nose conduit 4 completely.
This utility model structure is simple, easy to use, makes that the conversion of the mouth and nose of nose bile duct becomes quick, success rate is high, alleviates the misery of patient and the workload of operator, avoids the risk that existing mouth and nose conversion art may occur.
Above-mentioned detailed description of the invention is used for explaining and this utility model is described; instead of this utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make this utility model and change, all fall into protection domain of the present utility model.
