Anti- gastroesophageal reflux art exercise model under mis instruments as Figure 1-Figure 5, including using 3D printing technique
Esophagus model 1, diaphram model 2, stomach model 3, spleen model 8 and bottom plate 6 and the diaphragm produced in accordance with actual form and quality
Flesh frame 7, two diaphram framves 7 are separately fixed at the both sides of bottom plate 6, and the both ends of the diaphram model 2 are separately fixed at diaphram frame 7
On, the esophagus model 1 runs through diaphram model 2, and the stomach model 3 is connected with esophagus model 1, and stomach model 3 and spleen mould
Type 8 is placed side by side on bottom plate 6.
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, and the support column 71 is inserted in 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 in a 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 3 integral printing shaping of stomach model, and esophagus model 1 uses quality of rubber materials, diaphram model 2
Using hydrogel material, stomach model 3 uses silicone 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, four separation parsing esophagus, stomach, spleen, diaphram organs, distinguished with computer software
Establish Different Organs basis anatomical model；
B. according to four esophagus, stomach, spleen, diaphram organ organ pliabilities, using flexible material, height imitates not homogeneity
The physical characteristics such as ground, color, density, esophagus model 1, stomach model 3, spleen model 8, diaphram model 2 are printed one by one；
According to organ, the three-dimensional position in human abdominal cavity makes the bottom plate 6 of each organ of the accurate fixed placement of energy, esophagus support 5 to c
With diaphram frame 7；
Part in step c is mutually assembled into supporter by d, and then according to organ, three-dimensional position will walk in human abdominal cavity
Esophagus model 1, diaphram model 2, stomach model 3 and the spleen model 8 printed in rapid b is assembled on supporter.
Esophagus model 1 and 3 integral printing shaping of stomach model in the step b, and the double shower nozzles of printer are utilized in printing
Print simultaneously, the first shower nozzle prints hollow inner support thing, the PLA class materials that whole hollow inner support thing uses 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 removes.
When second shower nozzle prints stomach model 3 and esophagus model 1 from bottom to top, first using silicone 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 control is in 24-25 degree, humidity
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 diaphram, it is the bottom and the top in abdominal cavity in thoracic cavity between splanchnocoel, normal thickness is 0.22 ~ 0.28CM, this
Only embodying partial result in utility model, modeling prints to the high 8CM thickness 0.25CM soft materials of long 15CM, using materials A, in
Between leave 0.9CM diameter circular apertures and 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 uses, material is partially crisp, and 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 arrives in 2.4mm under normal circumstances
Be 2.7mm in the case where moderately expanding 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 elastic and pliability；
It is mainly esophagus and stomach orifice of the stomach and body of stomach position that the folded portion being related to is operated in gastroesophageal reflux art, so
It need to print with different flexibilities and hollow oesophagus and stomach orifice of the stomach and body of stomach position.This position is same using the double shower nozzles of printer
When print, shower nozzle 1 prints hollow inner support thing using PLA materials, and shower nozzle 2 prints prints stomach bottom point and esophageal from bottom to top
Point, first using material B, beat to changing material C in printer head during stomach orifice of the stomach top and finish esophagus printing, ensure stomach bottom and
The coherent integraty of esophagus has concurrently highly similar to the true soft durometer of human organ again, prints shower nozzle 1 after end to be printed
PLA materials remove, and numbering 2 is overall after keeping flat to be presented human body preceding fasted conditions to be treated.
Stomach bottom side rear spleen, the diaphragmatic surface of smooth protuberantia and the visceral surface two sides of depression can be divided into, spleen matter is crisp and soft, by
Hit cruelly rear broken, so need carefully to avoid in the treatment, material D use in printing, has the elasticity of muscle and frangible.
The bottom plate prints for PLA materials, it is therefore an objective to is 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.The diaphram frame
Being printed for PLA materials, it is therefore an objective to fixed diaphram, the height and diaphram of diaphram frame are three-dimensional high consistent, the breach of insertion bottom plate both sides,
Reuse clip to fix diaphram model both sides, form partition, esophagus model is passed through into reserved through hole.All parts separate
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 representative example of the present utility model.The utility model can also have many
Deformation.Every any simple modification, equivalent change and modification made according to essence of the present utility model to above example,
It is considered as belonging to the scope of protection of the utility model.
