Capsule medical apparatus and medical system

摘要

A capsule medical apparatus includes a tissue obtaining unit that obtains a tissue from a body site of a subject; a detecting unit that detects a state of the tissue obtaining unit that varies depending on whether the tissue obtaining unit succeeds in obtaining a tissue; an output unit that outputs information representing whether the tissue obtaining unit succeeds in obtaining a tissue; and a control unit that determines whether the tissue obtaining unit succeeds in obtaining a tissue based on the state of the tissue obtaining unit, which is detected by the detecting unit, and causes the output unit to output the information representing whether the tissue obtaining unit succeeds in obtaining a tissue.

主权项

1. A capsule medical apparatus comprising:
a capsule casing: a tissue obtaining unit having: a forceps-shaped obtaining unit configured to protrude from and retract into the capsule casing to obtain a tissue from a body site of a subject; and a housing unit configured to house the forceps-shaped obtaining unit; a detecting unit that detects a state of the tissue obtaining unit that varies depending on whether the tissue obtaining unit succeeds in obtaining the tissue, the detecting unit being a photosensor having a light emitter and a light receiver, the light emitter and the light receiver being arranged on a wall of the housing unit such that the light emitter and the light receiver face each other; an output unit that outputs information representing whether the tissue obtaining unit succeeds in obtaining the tissue to outside of the subject; and a control unit that determines whether the tissue obtaining unit succeeds in obtaining the tissue based on the state of the tissue obtaining unit, which is detected by the detecting unit, and causes the output unit to output the information representing whether the tissue obtaining unit succeeds in obtaining the tissue, the control unit being arranged in the capsule casing, wherein if the tissue obtaining unit does not succeed in obtaining the tissue, the control unit causes the tissue obtaining unit to perform a tissue obtaining operation again and causes the output unit to output the information representing the success in obtaining the tissue when the tissue obtaining unit succeeds in obtaining the tissue, and when the forceps-shaped obtaining unit is housed in the housing unit, the control unit determines whether the tissue is obtained in tips of the forceps-shaped obtaining unit based on whether the light receiver receives light from the light emitter.
