Abstract
Provided is an organ model having a property such that each layer suitably peels off, a property such that sliding or a sense of catching is present besides a sense of elasticity that is felt when a surgical knife cuts the organ model open, and a property such that ligation can be performed without burying of a suture thread, and a property such that a knot of the thread gets caught on the organ model. An organ model being a laminated body in which plural layers each formed of a hydrogel material are laminated, and one or more of the layers is each a fiber group-containing layer in which fiber groups are approximately continuously present inside the layer and over the plane of the layer.
Claims26
An organ model being a laminated body,
- wherein the laminated body comprises plural layers that are laminated and each formed of a hydrogel material,
- wherein one or more of the layers is each a fiber group-containing layer in which fiber groups (except for fibrous structures made of collagen) are approximately continuously present inside the layer and over the plane of the layer, and
- wherein a layer that is adjacent to the fiber group-containing layer is capable of being peeled off in the vicinity of an interface between the fiber group-containing layer and the adjacent layer.
An organ model being a laminated body,
- wherein the laminated body comprises plural layers that are laminated and each formed of a hydrogel material,
- wherein one or more of the layers is each a fiber group-containing layer in which fiber groups are approximately continuously present inside the layer and over the plane of the layer,
- wherein a layer that is adjacent to the fiber group-containing layer is capable of being peeled off in the vicinity of an interface between the fiber group-containing layer and the adjacent layer, and
- wherein the laminated body further comprises a layer enclosing fibers, wherein the fibers have a three-dimensional mesh structure.
An organ model being a laminated body,
- wherein the laminated body comprises plural layers that are laminated and each formed of a hydrogel material,
- wherein one or more of the layers is each a fiber group-containing layer in which fiber groups are approximately continuously present inside the layer and over the plane of the layer, and
- wherein the one or more of the layers comprise:
- a fiber group-containing layer enclosing a first fiber group;
- and a fiber group-containing layer enclosing a second fiber group, or
- the one or more of the layers comprise a fiber group-containing layer enclosing at least the first fiber group and the second fiber group, and
- wherein the first fiber group and the second fiber group are capable of being peeled off.
An organ model being a laminated body,
- wherein the laminated body comprises plural layers that are laminated and each formed of a hydrogel material,
- wherein one or more of the layers is each a fiber group-containing layer in which fiber groups are approximately continuously present inside the layer and over the plane of the layer, and
- wherein the laminated body has only one of the fiber group-containing layers, and has a tubular shape when the laminated body is seen from a cross-sectional surface in the lamination direction, and
- wherein a layer that is adjacent to the fiber group-containing layer is capable of being peeled off in the vicinity of an interface between the fiber group-containing layer and the adjacent layer.
An organ model being a laminated body,
- wherein the laminated body comprises plural layers that are laminated and each formed of a hydrogel material,
- wherein one or more of the layers is each a fiber group-containing layer in which fiber groups are approximately continuously present inside the layer and over the plane of the layer,
- wherein the hydrogel material contains a polyvinyl alcohol, and
- wherein a layer that is adjacent to the fiber group-containing layer is capable of being peeled off in the vicinity of an interface between the fiber group-containing layer and the adjacent layer.
