Abstract
A method of making a tissue model comprises determining one or more material properties of a tissue, wherein the one or more material properties include at least one of mechanical properties, electroconductive properties, optical properties, thermoconductive properties, chemical properties, and anisotropic properties, creating an anatomical structure of the tissue, selecting an artificial tissue material having one or more material properties that substantially correspond to the one or more material properties of the tissue, and coupling the artificial tissue material to the anatomical structure.

A method of making a training model for training a medical or veterinary practitioner on performance of a medical or veterinary procedure, the method comprising:
- determining one or more first deformability properties of a soft tissue that is part of an anatomical system relevant to the procedure, the soft tissue having an anatomical structure within the relevant anatomical system, wherein the one or more first deformability properties include a Young's modulus of the soft tissue within the relevant anatomical system;
- selecting a composition of a silicone-based model material comprising an organosilicate material including a platinum-based silicone rubber or a tin-cured silicone rubber so that, when cured, the silicone-based model material will have one or more second deformability properties that are within 10% of the one or more first deformability properties of the soft tissue within the relevant anatomical system;
- applying the silicone-based model material onto a model support structure and thereby forming a tissue model having a geometry that corresponds to the anatomical structure of the soft tissue;
- and
- curing the applied silicone-based model material and thereby forming the training model such that the cured silicone-based model material has the geometry that corresponds to the anatomical structure of the soft tissue within the relevant anatomical system and such that the cured silicone-based model material has the one or more second deformability properties that are within 10% of the one or more first deformability properties of the soft tissue.
A training model for training a medical or veterinary practitioner on performance of a medical or veterinary procedure, the training model comprising:
- a three-dimensional support structure;
- and
- a silicone-based model material coupled to the three-dimensional support structure, the silicone-based model material comprising an organosilicate material including a platinum-based silicone rubber or a tin-cured silicone rubber, wherein the silicone-based model material has a geometry that corresponds to an anatomical structure of a corresponding soft tissue that is part of an anatomical system relevant to the procedure, wherein a composition of the silicone-based model material is selected to have one or more deformability properties, including a Young's modulus of the silicone-based model material, wherein the one or more deformability properties of the silicone-based model material are within 10% of one or more corresponding deformability properties of the corresponding soft tissue within the relevant anatomical system, the one or more corresponding deformability properties including a Young's modulus of the soft tissue within the relevant anatomical system.
A training model for training a medical or veterinary practitioner on performance of a medical or veterinary procedure, the training model comprising:
- a three-dimensional support structure;
- and
- a silicone-based model material coupled to the three-dimensional support structure, wherein the silicone-based model material has a geometry that corresponds to an anatomical structure of a corresponding soft tissue that is part of an anatomical system relevant to the procedure, wherein the anatomical structure of the corresponding soft tissue includes a plurality of at least three tissue layers,
- wherein the silicone-based model material coupled to the three-dimensional model structure comprises a plurality of at least three layers of the silicone-based model material, wherein each layer of the silicon-based model material has a layer geometry that corresponds to a corresponding anatomical structure of a corresponding one of the plurality of at least three tissue layers, and
- wherein a composition of the silicone-based model material of each of the plurality of at least three layers is selected to have one or more deformability properties, including a Young's modulus of the silicone-based model material, that are within 10% of one or more corresponding deformability, properties of the corresponding one of the plurality of at least three tissue layers, the one or more corresponding deformability properties including a Young's modulus of the soft tissue at the corresponding one of the plurality of at least three tissue layers.
