Abstract

An organ model for endoscope includes: a basic shape part formed by imitating a shape of a tubular organ; and a tissue holding part that holds a tissue piece and is detachably provided with respect to the basic shape part. The tissue holding part includes: a main body that is formed in a tubular shape and has a window part communicating with an internal space, on an outer peripheral surface; and a fixing member that fixes the tissue piece on the main body such that at least a portion of the tissue piece overlaps the window part. The main body is rotatable in a circumferential direction of the main body with respect to the basic shape part, in a state where the main body is attached to the basic shape part.

First claim

What is claimed is:

1. An organ model for endoscope comprising:
a basic shape part formed by imitating a shape of a tubular organ; and
a tissue holding part configured to hold a tissue piece and is detachably provided with respect to the basic shape part,
wherein the tissue holding part includes:
a main body that is formed in a tubular shape and has a window part communicating with an internal space of the main body, the window being arranged on an outer peripheral surface of the main body; and
a fixing member that is attached to the main body and is configured to fix the tissue piece on the main body such that at least a portion of the tissue piece overlaps the window part and a peripheral portion of the tissue piece overlapping the window part is fixed to a periphery of the window part; and
wherein the main body is configured to be rotatable in a circumferential direction of the main body with respect to the basic shape part, in a state where the main body is attached to the basic shape part.

2. The organ model for endoscope according to claim 1 , wherein
the fixing member has a projection part, and
the main body has a fixing hole that communicates with the internal space of the main body, so that the projection part can enter into the fixing hole.

3. The organ model for endoscope according to claim 2 , wherein the fixing hole is provided at a position that does not overlap the window part in an axial direction of the main body.
