Specific embodiment
Hereinafter the possible state sample implementation of the present invention is only illustrated with embodiment, is so not intended to limit the invention and to be protectedScope, conjunction are first chatted bright.
Fig. 1 to Fig. 6 is please referred to, shows a preferred embodiment of the invention, operation stitching training aids of the invention, packetInclude an ontology 1.
The ontology 1 is equipped with an imitative meat tissue 2 and an at least cutting mouth 3, which includes along a thickness direction 81At least internal layer body 4 stacked and a surface layer body 5, which is located at an at least internal layer body 4, and relatively above, this is at leastOne cutting mouth 3 is opened in the wound of the surface layer body 5 to simulate human body with extending along the thickness direction 81.Wherein, the imitative meat tissue 2For one fill liquid syringe 9 insertion be connected to an at least cutting mouth 3, and then the liquid of the syringe can flow into this at least oneCutting mouth 3, and then simulate practical blood stream artificial situation (i.e. blood exudation mechanism) can be used to after simulation test sutures this extremely wherebyWhether the blood of a few cutting mouth 3 can ooze out, and examine suture quality whereby.
The porosity of the surface layer body 5 is preferably the porosity for being less than the respectively internal layer body 4；In other words, the density of the surface layer body 5It is higher, epidermis harder in human body skin and flesh tissue is gone out to real simulation, and the density of an at least internal layer body 4 is lower, it canMore tender skin corium, subcutaneous tissue or fat in the human body skin and flesh tissue of selection simulation on demand.
More carefully say, the porosity of the surface layer body 5 between 0% to 10% (i.e. packed density between 90% to100%), each porosity of the internal layer body 4 (i.e. packed density is between 10% to 60%) between 40% to 90%.More carefullyGround says, the quantity of an at least internal layer body 4 is two and is respectively defined as one first internal layer body 41 and one second internal layer body 42, thisOne internal layer body 41 between the surface layer body 5 and the second internal layer body 42, and each layer body thickness it is descending be sequentially thisTwo internal layer bodies 42, the first internal layer body 41 and the surface layer body 5.
In the present embodiment, for the first internal layer body 41 to simulate skin corium, the second internal layer body 42 is subcutaneous to simulateTissue and fat, therefore the porosity of the second internal layer body 42 can be greater than the porosity of the first internal layer body 41, and first internal layerThe porosity of body 41 is greater than the porosity of the surface layer body 5.Also, the imitative meat tissue 2 is preferably made of silica gel material, and compared with energyTightness after showing elasticity identical with the actual human body human body, texture and suturing.In addition, the surface layer body 5 and this at least oneLayer body 4, which is preferably successively to stack via the gimmick of 3D printing in the thickness direction 81, is connected to the imitative meat tissue 2, reaches fast fast-growingThe purpose of production.
It is noted that in order to allow the operation stitching training aids that can have maximum availability, an at least cutting mouth 3Quantity is preferably a plurality of, and the plural number cutting mouth 3 preferably depth respectively on the thickness direction 81 is all different, allows practitionerIt can practice the wound of various different depths to accumulate different suture skills and experience, to various in the state that can face the realityWound.Certainly, in other embodiments, plural cutting mouth 3 can be set with similarly depth also without can not.
More specifically, respectively the cutting mouth 3 at least penetrated through the surface layer body 5 on the thickness direction 81, such depthSimulation wound can just be really achieved the purpose of suture training.More specifically, which is between an orientation 82Every arrangement, depth of the plural number cutting mouth 3 on the thickness direction 81 is gradually increased along the orientation 82, allows practitioner's energyIt is enough rapidly to pick out which cutting mouth 3 have most deep depth, can more allow practitioner that can practice the different depths in orderSimulate wound.In the present embodiment, the quantity of an at least cutting mouth 3 is five, table of the plural number cutting mouth 3 in the surface layer body 5Face is formed by that shape is identical, with towards 5 sight of surface layer body, respectively the linear shape of the cutting mouth 3 is to strengthen basic exercise.Certainly, in other embodiments cutting mouth 3 can curved, irregular shape come as advanced practice.
It is understood that respectively the cutting mouth 3 is voluntarily cut again after taking the imitative meat tissue 2 by practitioner, such asThis can ensure that the entire imitative meat tissue 2 less has foreign matter and runs inside it, to maintain the quality of the entire imitative meat tissue 2.Compared withGoodly, the ontology 1 additionally comprise at least one for block blade stop section 6, at least a stop section 6 is buried with a predetermined depth for thisMeat tissue 2 is imitated set on this, the quantity of an at least stop section 6 is equal to the quantity of an at least cutting mouth 3.Wherein, this is defaultDepth is the cutting mouth 3 depth capacity on the thickness direction 81, and the depth of the cutting mouth 3 can be grasped with effective auxiliary exercise personDegree, and can avoid blade and accidentally injured through the imitative meat tissue 2.
The operation stitching training aids has additionally comprised a pedestal 7 other than above structure and has carried out suture instruction with auxiliary exercise personPractice.Compared with furthermore, it is understood that the pedestal 7 is recessed with a holding part 71, which is separably placed in the holding part 71.Wherein,The pedestal 7 is made of plastic cement material, and the hardness of the pedestal 7 is greater than the hardness of the ontology 1, and therefore, practitioner is being cut intoCooperate the stop section 6 that there can be duplicate protection effect when the cutting mouth 3.Also, the pedestal 7 can isolate arround sundries, make it notThe ontology 1 can be touched or be influenced, and then reaches the actuation space for defining and carrying out suture operation.In addition, the holding part 71 is moreThe ontology 1 can be limited to avoid its any sliding.
More specifically, a ring-side wall 74 of the pedestal 7 separately provides at least perforation 72 for being connected to the holding part 71,The direction of an at least perforation 72 is transverse to the thickness direction 81, and respectively the perforation 72 wears the insertion imitative meat group for the syringe 92 are knitted so that liquid (such as red pigment), paste viscous body are injected the imitative meat tissue 2.It, can when practitioner is intended to practiceWith to allow liquid, constantly by this, at least a cutting mouth 3 flows out through the above way, analog goes out the bleeding of true wound wherebySituation allows practitioner that can experience the true telepresenc such as atmosphere of urgent danger, and then can gradually increase in constantly practiceAdd crushing resistance, enables suture gimmick more and more stable.Also, after practitioner's suture, it can also come in this wayExamine suture after quality, viewing liquid whether can be leaked out by the cutting mouth of this after suturing 3, and then find out flaw place intoRow practice improves.
In the present embodiment, the quantity of an at least perforation 72 is two, and is had since the deeper wound of depth just comparesA large amount of blood, therefore, two perforation 72 respectively correspond depth is most deep on the thickness direction 81 in the plural number cutting mouth 3 twoIt is a, and have true simulation effect.
Preferably, the bottom wall 75 of the pedestal 7 separately provide the connection holding part 71 support mouth 73, this supports mouth 73The parallel thickness direction 81 of opening direction, this is supported mouth 73 and supplies an object by being detached from the holding part 71 to push against the ontology 1, withConvenient for the new ontology 1 of practitioner's quick-replaceable.
To sum up, operation stitching training aids of the present invention can more accurately simulate human skin structure, and energy band is to white silk wherebyHabit person's more accurately feel reduces the trained difference with actual environment so that practitioner be able to maintain when encountering practical suture it is existingHand feeling quality.Also, sewing effect can be examined by syringe injecting fluid in training process, with further to suture afterWound do and more scrupulously require, and suture quality and skill is substantially improved.
