GUIDING-TYPE MEDICAL SYSTEM
A medical appliance is easily inserted into a desired blood vessel route. There is provided a guiding-type medical system, including: a cylindrical or linear guidewire made of an elastic body that can be inserted into a blood vessel; and a guiding device having a device head portion that can be inserted into a body to guide the guidewire inserted into the blood vessel. The device head portion includes: an ultrasonic array element that can perform an ultrasound scan along one plane to acquire an ultrasound image; and a permanent magnet linearly movable in a direction along the one plane. At a distal end of the guidewire, a magnetic head on which magnetic attraction force induced by the permanent magnet is made to act is provided.
1 . A guiding-type medical system, comprising:
a cylindrical or linear medical appliance made of an elastic body that can be inserted into a blood vessel; and
a guiding device having an insertion portion that can be inserted into a body to guide the medical appliance inserted into the blood vessel, wherein
the insertion portion includes:
an ultrasound probe that can perform an ultrasound scan along one plane to acquire an ultrasound image; and
a magnet linearly movable in a direction along the one plane, and
at a distal end of the medical appliance, a magnetic member made of a magnetic material on which magnetic attraction force induced by the magnet is made to act is provided.
2 . The guiding-type medical system according to claim 1 , wherein the magnetic member is a magnet having a generally spherical shape and having polarity in a radial direction.
3 . The guiding-type medical system according to claim 1 , wherein the magnet is an electromagnet.
4 . The guiding-type medical system according to claim 1 , wherein the distal end of the medical appliance is shaped to have projections and indentations on an outer surface thereof.
5 . The guiding-type medical system according to claim 1 , wherein the ultrasound probe is placed at both sides of the magnet of the insertion portion.
