The tooth seat main body upper side of the arcuation seat of/mono- circle, upper left tooth seat and upper right tooth seat is provided with to be adapted with arranging thread form shape on people
Upper groove, the tooth seat main body downside of left lower tooth seat and right lower tooth seat be provided with arranged under people thread form shape be adapted it is recessed
Groove, tooth can be fixed by biting groove with corresponding tooth seat, and tooth seat main body is fixedly connected by connecting rod with arcuation seat, when four
When individual tooth seat is all fixed on tooth, upper left Ya Zuo lower surfaces and left lower tooth seat upper surface apical grafting, upper right tooth seat lower surface and the right side
Lower tooth seat upper surface apical grafting, patient mouth is strutted, upper left tooth seat, upper right tooth seat, the arcuation seat energy of left lower tooth seat and right lower tooth seat
Just docking forms an annulus, and extension fixture includes hollow tube, and hollow tube front end connects a water pocket, and rear end sets an interface,
Extension fixture also includes injector, and injector can be connected on interface and be connected with hollow tube, and one in front and one in back two are fixed with hollow tube
Individual spacing ring, the annular diameters of annulus are more than the external diameter of hollow tube, but are less than the external diameter of spacing ring.
To optimize above-mentioned technical proposal, the concrete measure taken also includes：
The quantity of above-mentioned injector is multiple, and injector is water filling rubber bag tank, and the size of these water filling rubber bag tanks is each not
It is identical.
A segment distance is provided with one on hollow tube between two above-mentioned spacing rings and touches projection.
Between above-mentioned touch is raised at intervals of 5m.
Above-mentioned water pocket is silicon capsule, the fully wrapped around hollow tube front end of water pocket.
The frictional layer for increasing tooth seat and tooth frictional force is pasted with above-mentioned upper groove and low groove.
Above-mentioned connecting rod and arcuation seat is stainless steel.
The utility model domestic type oesophageal dilator, it is maximum the characteristics of be to devise tooth seat, by tooth seat mounted in patient or so
On the two rows tooth of both sides, patient stings tightly, and mouth be able to not can close, and in front tooth cavity formed below, arcuation seat is at the cavity
Annulus is constituted, extension fixture passes through the annulus, using the annulus as fulcrum, water pocket stretched into oesophagus, tooth seat can allow patient to sting
Tightly, solve the sense of discomfort that patient opens one's mouth for a long time, while a fulcrum can also be produced, make patient not have to help extension fixture,
A hand is liberated, patient is slided extension fixture into oesophagus with a hand, it is water pocket that a hand, which is used to extrude injector,
Water filling, make it possible that patient voluntarily expands oesophagus.The utility model is expanded using water pocket to oesophagus, and water pocket is compared with air bag
Weight is bigger, can be by weight to slip below oesophagus, and without being pushed hard with hand, more difficult injury oesophagus, water pocket exists
When being extruded at lemostenosis, deformation is also smaller, can be preferably to mega-esophagus.One in front and one in back two are fixed with hollow tube
Spacing ring, the insertion depth of extension fixture can be limited, prevent patient from inserting too deep or excessively shallow, and the touch on hollow tube is raised
Making patient in the case where can't see extension fixture, the depth of insertion can be known that by touching hollow tube, it is very easy to use.
