Two middle side parts of the bottom plate 6 are provided with breach 61, and the diaphram frame 7 includes clamp 73, support column 71 and base piece
72, the base piece 72 is vertically fixed on one end of support column 71, the clamp 73 be located at the upper end of base piece 72 and with support
Post 71 is vertically fixed, in the insertion of support column 71 breach 61, and clamp 73 and base piece 72 clamp up and down the two of bottom plate 6 respectively
Side.
The upper end of the bottom plate 6 is additionally provided with the esophagus support 5 for placing esophagus model 1, and the esophagus support 5 includes arc support
Lath 51 and U-shaped fixed block 52, the arc pallet bar 51 are fixed on the side wall of U-shaped fixed block 52, the U-shaped fixed block
52 are connected to one end of bottom plate 6.
The arc pallet block 4 for placing stomach model 3 and spleen model 8, the diaphram mould are further fixed on the bottom plate 6
Type 2 is provided with the through hole 21 passed through for esophagus model 1.
The esophagus model 1 and the integral printing shaping of stomach model 3, and esophagus model 1 uses quality of rubber materials, diaphram model 2
Using hydrogel material, stomach model 3 uses silicon rubber material, and spleen model 8 uses plastic material.
The preparation method of anti-gastroesophageal reflux art exercise model, comprises the following steps under a kind of mis instruments,
A. by medical image processing, separation parsing esophagus, stomach, spleen, four organs of diaphram are set up respectively with computer software
Different Organs basis anatomical model；
B. according to esophagus, stomach, spleen, four organ organ pliabilities of diaphram, using flexible material, height imitate differing texture,
The physical characteristics such as color, density, esophagus model 1, stomach model 3, spleen model 8, diaphram model 2 are printed one by one；
Bottom plate 6, esophagus support 5 and diaphragms of the c according to organ each organ of the accurate fixed placement of three-dimensional position making energy in human abdominal cavity
Flesh frame 7；
Part in step c is mutually assembled into supporter by d, then according to organ in human abdominal cavity three-dimensional position by step b
In the esophagus model 1, diaphram model 2, stomach model 3 and the spleen model 8 that print be assembled on supporter.
The integral printing shaping of esophagus model 1 and stomach model 3 in the step b, and utilize in printing the double shower nozzles of printer
Print simultaneously, the first shower nozzle prints hollow inner support thing, the PLA class materials that whole hollow inner support thing is used using PLA materials
Can also be that PLA, high impact polystyrene, PLA, metal, ceramics etc. are any accumulates printed material；Second shower nozzle
Stomach model 3 and esophagus model 1 are printed from bottom to top, by the hollow interior branch of the PLA materials of the first nozzle printing after end to be printed
Support thing is removed.
When second shower nozzle prints stomach model 3 and esophagus model 1 from bottom to top, first using silicon rubber material, beat to stomach model 3
Stomach orifice of the stomach top when printer head in change quality of rubber materials by esophagus model 1 printing finish, make stomach model 3 and esophagus model
1 coherent integraty has concurrently highly similar to the true soft durometer of human organ again.
Whole printing process uses totally-enclosed working condition in the step b, and room temperature is controlled in 24-25 degree, and humidity is
15%-16%, and respectively by printer head heating-up temperature when printing diaphram model 2, esophagus model 1, stomach model 3, spleen model 8
Control is in 220 degree, 180 degree, 200 degree and 160 degree.
The PLA materials of the hollow inner support thing include PLA, high impact polystyrene, PLA, metal, ceramics
In one or more mixtures.
Human body is every flesh, between splanchnocoel, is the bottom and the top in abdominal cavity in thoracic cavity, and normal thickness is 0.22 ~ 0.28CM, this
Partial result is only embodied in invention, modeling prints to the high 8CM thickness 0.25CM soft materials of long 15CM, and using materials A, centre is stayed
There are 0.9CM diameter circular apertures to be used for esophageal perforation.
Human body esophagus is a passage being made up of muscle shape, is about the mm of 20 ~ 25cm thickness >=5, connection throat to stomach,
Easily tear, so the flexible material B that printing is used, material is partially crisp, the top of human stomach deserves to be called gastral cavity, including orifice of the stomach, during middle part claims
Gastral cavity, i.e. body of stomach position, bottom claim pylorus, including pylorus, and adult's wall of stomach thickness average value is arrived in 2.4mm under normal circumstances
Be 2.7mm under moderately expansion between 2.7mm, be 2.4mm under abundant expansion, it is different from esophagus thickness, it is more tensioned with
Elasticity, so printing uses flexible material C, more elasticity and pliability；
The folded portion being related to is operated to be mainly esophagus and stomach orifice of the stomach and body of stomach position in gastroesophageal reflux art, so need to beat
Print off with different flexibilities and hollow oesophagus and stomach orifice of the stomach and body of stomach position.This position is beaten simultaneously using the double shower nozzles of printer
Print, shower nozzle 1 prints hollow inner support thing using PLA materials, and shower nozzle 2 prints printing stomach bottom point and esophagus part from bottom to top,
Material B is first used, replacing material C is beaten to printer head during stomach orifice of the stomach top and finishes esophagus printing, it is ensured that stomach bottom and food
The coherent integraty in road has, the PLA that to be printed end after prints shower nozzle 1 highly similar to the true soft durometer of human organ concurrently again
Material is removed, and numbering 2 is overall after keeping flat to be presented human body preceding fasted conditions to be treated.
Stomach bottom side rear spleen, can be divided into the diaphragmatic surface of smooth protuberantia and the visceral surface two sides of depression, and spleen matter is crisp and soft, by
Hit rear broken cruelly, so needing carefully to avoid in the treatment, material D is used in printing, has the elasticity of muscle again frangible.
The bottom plate prints for PLA materials, it is therefore an objective to stayed for fixed stomach model, esophagus model, spleen model particular location
Fluted, esophagus support prints for PLA materials, inserts the top of bottom plate, it is therefore an objective to the top of fixed esophagus model.It is described every flesh frame
Printed for PLA materials, it is therefore an objective to fixed diaphram, the height of diaphram frame is three-dimensional high consistent with every flesh, the breach of insertion bottom plate both sides,
Reusing clip will be fixed every muscle model both sides, form partition, and esophagus model is passed through into reserved through hole.All parts are separated
Printing, be easy to doctor repeatedly preoperative exercise when cause individual part to be lost, then print substitute, with respect to integral replacing cost more
It is low.
It should be pointed out that above example is only the representative example of the present invention.The present invention can also have many deformations.It is every
Any simple modification, equivalent variations and modification that essence according to the present invention is made to above example, are considered as belonging to this
The protection domain of invention.
