摘要:
Using a guidance system with a simple configuration, propulsive motion along a longitudinal direction and changing of the propulsion direction are easily performed with good precision and stability. There is provided a capsule-type medical apparatus which is inserted into the body of a subject and is guided by an external magnetic field, the capsule-type medical apparatus comprising: a substantially cylindrical capsule; a propulsion mechanism for converting rotary motion about a longitudinal axis R of the capsule into propulsive motion along the longitudinal axis R; a magnet accommodated inside the capsule and disposed in such a manner that the magnetic-pole direction thereof can be switched between a direction along the longitudinal axis R and a direction intersecting the longitudinal axis R; and a securing portion for securing the magnet to the capsule in each of the switched states of the magnetic-pole direction.

Provided is an intra-subject medical system which includes a body-insertable device and a physical quantity generator. The body-insertable device is to be introduced into a subject, is covered by a capsule-shaped exterior member, and includes a physical quantity detecting member which has a directivity to detect a predetermined physical quantity; at least one functional member which has a necessary function for examining or treating inside the subject; and a switch control unit which controls an on/off state or operation mode of the at least one functional member when the physical quantity detecting member detects a physical quantity. The physical quantity generator has a physical quantity emitting unit which emits a temporary physical quantity inside the subject; and a physical quantity direction changing unit which changes an emission direction of the physical quantity.

A medical device control system improves an inducing stability and operability of a medical device having its direction controlled with magnetism, which is used for the inspection or treatment in a subject's body. The control system is formed of a medical device including an insertion member inserted into the subject's body, and a magnetic field response portion disposed within the insertion member for generating torque in response to the magnetic field applied from outside the subject's body, a direction detection unit that detects an insertion direction of the insertion member, a user interface through which the information with respect to the control of the insertion direction is input and output, a magnetic field generation portion that generates a magnetic field that directs the insertion member to a control direction, and a user interface control unit that controls the user interface based on a discordance between the control direction and the insertion direction.
