A method and device of creating a lumen model in a microwell plate defining a well is provided. A rod is inserted through the well of the microwell plate and the well is filled with a polymerizable material. The material is polymerized in the well. The rod is removed from the well of the microwell plate such that the polymerized material defines a lumen.

[Problem to be Solved by the Invention]

To provide an artificial tissue model that can be more advantageously used in surgical technique training compared to previous artificial tissues, as well as a method of fabricating the same.

[Solution]

An artificial organ model for surgical technique training comprising two or more fibrous layers 2, 3 layered and bonded to each other so as to be peelable by a surgical technique performed by a surgical technique trainee; the layered and bonded two or more fibrous layers 2, 3 as a whole being saturated with an electroconductive liquid or gel; and two adjacent fibrous layers out of the two or more fibrous layers being formed from different materials or substances or in different colors so as to be recognizable as different membranes by the surgical technique trainee.

The present disclosure relates to a coating solution composition for a 3D model, that includes a rubber material and an organic solvent, a preparation method thereof, and a preparation method of a 3D model using the same. When a 3D model is coated using the coating solution composition for a 3D model of the present disclosure, the coated 3D model will have a similar elasticity and strength as those of an organ, thus enabling surgical simulation, and therefore, it can be used in surgeries that require surgical simulation due to the small size of pediatric hearts and the like and variety and complexity of related diseases, thereby inducing successful surgeries, and thus it can be widely used in the medical industry.

A method of forming a three-dimensional object 38 with a shape determined by model data defining a model 10 of the object, characterized by the steps of: a) splitting the model 10 into a high elevation/low resolution base part 18 and a low elevation/high resolution cover part 20′; b) forming a base body 30 with a shape as determined by the base part 18 of the model; c) employing a 3D printing technique for printing a sheet-like cover body 34 with a shape as determined by the cover part 20′ of the model; and d) matching the cover body 34 to the base body 30 by vacuum forming.

A nasal impression assembly for use in prosthodontics and otolaryngology, wherein the assembly includes detachable components specifically designed for recording precise nasal impressions. The detachable components may include plurality of nasal cones, a pair of injection syringes, and an extra nasal mesh splint, assembled on a horizontal bar. Further a method is provided for measuring/imprinting the impression, by using the assembly, wherein an impression material is brought in contact with extra-nasal and/or intra-nasal structure to imprint its size and/or shape.

A method for fabricating a light-transmitting blood vessel model is provided and comprises steps of: providing a male mold; performing a female mold forming step to form a female mold on an outer surface of the male mold, wherein the female mold forming step comprises: performing an adhesion step such that the female mold solution is adhered onto the outer surface of the male mold, wherein the adhesion step is a dipping step or a spraying step; performing a drying step of drying the female mold solution on the outer surface of the male mold; and repeating the adhesion step and the drying step for 3 to 4 times to form the female mold; and dissolving the male mold by a solution to cause the remaining female mold to form the light-transmitting blood vessel model. A simulated blood vessel model can be formed by the method.

Systems and methods are disclosed for an injection training model that includes a base structure, an anatomical subassembly mechanically secured to the base, and a ballistic gel structure. The anatomical subassembly includes a first set of 3D-printed components manufactured from a first material, and a second set of 3D-printed components manufactured from a second material, wherein the first material has a greater stiffness than the second material. The ballistic gel structure encapsulates the anatomical subassembly and is transparent, repairable, and inorganic.

A system and method for identifying test bars formed during a selective laser sintering build. A part cake is formed during a selective laser sintering build. The part cake comprises parts formed from a powder by selective laser sintering and unsintered powder around the formed parts. The parts include test bars for performing material testing. Each test bar includes a plurality of indentations in a first grip section and a second grip section. The plurality of indentations are arranged in a information providing pattern that is adapted to be readable after the test part is removed from the part cake.

The present disclosure relates to a tool used to producing anatomical phantoms. The tool includes an inner flexible mold which sits inside a rigid, thermally conductive outer shell. The rigid shell may be made out of aluminum. The silicone mold and thermally conductive shell both include at least two interlocking components. The shell is held together by a locking mechanism which can expand upon internal pressure. An anatomical phantom is produced from polyvinyl alcohol hydrogel by freezing and thawing a PVA liquid precursor in the silicone mold and demolding it.

Disclosed are various embodiments for a dynamic flow apparatus for cardiovascular diagnosis and pre-procedure analysis of individual patients. The dynamic flow apparatus includes a three-dimensional (3D) cardiac model in an enclosed container. The 3D cardiac model can mimic an operation of an actual heart by pumping fluid through the 3D cardiac model and causing the model to expand and contrast. Data obtained from the operation of the 3D model can be used during a surgical procedure of an actual heart of an individual.
