Abstract
A human body model is disclosed that can make an image acquired by a medical device similar to an image of a body lumen acquired during surgery. The human body model includes a main body portion that includes a lumen passing through a portion of the main body portion between a first surface and a second surface disposed on a side opposite to the first surface, and a tubular body that is provided in at least a part of the lumen and is made of another material different from the material of the main body portion. An acoustic impedance of the material of the tubular body being equal to an acoustic impedance of a body lumen, and a hardness of the material of the main body portion being higher than a hardness of the material of the tubular body.
Claims17
A human body model used for at least one of basic study and technique acquisition for a medical device that is inserted into a body lumen and acquires an image of an inside of the body lumen by using ultrasound waves, the human body model comprising:
- a main body portion having a lumen passing through a portion of the main body portion between a first surface of the main body portion and a second surface of the main body portion, the second surface of the main body portion being arranged on a side opposite to the first surface of the main body portion, the main body portion including one of a convex portion and a concave portion that are fitted to each other;
- a tubular body provided in at least a part of the lumen, the tubular body being made of a material different from a material of the main body portion, the tubular body including an other of the convex portion and the concave portion that are fitted to each other;
- an acoustic impedance of the material of the tubular body being equal to an acoustic impedance of the body lumen;
- and
- a hardness of the material of the main body portion being higher than a hardness of the material of the tubular body.
A system for at least one of basic study and technique acquisition for a medical device that is inserted into a body lumen and acquires an image of an inside of the body lumen using ultrasound waves, the system comprising:
- a plurality of human body models, each of the plurality of human body models including a main body portion having a lumen passing through a portion of the main body portion between a first surface of the main body portion and a second surface of the main body portion, the second surface of the main body portion being arranged on a side opposite to the first surface of the main body portion, a tubular body provided in at least a part of the lumen, the tubular body being made of a material different from a material of the main body portion, and an acoustic impedance of the material of the tubular body being equal to an acoustic impedance of the body lumen;
- and
- each of the plurality of human body models being connected along a longitudinal axis of each of the lumens.
A method for at least one of basic study and technique acquisition for a medical device that is inserted into a body lumen and acquires an image of an inside of the body lumen using ultrasound waves, the method comprising:
- providing a plurality of human body models, each of the plurality of human body models including a main body portion having a lumen passing through a portion of the main body portion between a first surface of the main body portion and a second surface of the main body portion, the second surface of the main body portion being arranged on a side opposite to the first surface of the main body portion, a tubular body provided in at least a part of the lumen, the tubular body being made of a material different from a material of the main body portion, and wherein an acoustic impedance of the material of the tubular body is equal to an acoustic impedance of the body lumen;
- connecting each of the plurality of human body models to one another along a longitudinal axis of each of the lumens;
- and
- inserting the medical device into the lumens of the plurality of human body models.
