MEDICAL SYSTEM AND OPERATION METHOD
A medical system includes an insertion part inserted into an inside of a body; an arm part provided on the insertion part and capable of moving with respect to the insertion part; a device disposed in the inside of the body; a holding part provided on the arm part and holding the device; and a part to be held provided on the device and held by the holding part.
1 . A medical system comprising:
an insertion part inserted into an inside of a body;
an arm part provided on the insertion part and capable of moving with respect to the insertion part;
a device disposed in the inside of the body;
a holding part provided on the arm part and holding the device; and
a part to be held provided on the device and held by the holding part.
2 . The medical system according to claim 1 , wherein at least one of the holding part and the part to be held has a restriction part that restricts movement of the device.
3 . The medical system according to claim 1 , wherein the holding part has a grip part that grips the part to be held, and the part to be held has a part to be gripped capable of engaging with the grip part.
4 . The medical system according to claim 2 , wherein the holding part has a grip part that grips the part to be held, and the part to be held has a part to be gripped capable of engaging with the grip part.
5 . The medical system according to claim 1 , wherein the holding part and the part to be held have concave-convex shapes engaging with each other.
6 . The medical system according to claim 1 , wherein the holding part and the part to be held engage with each other through frictional force.
7 . The medical system according to claim 1 , wherein a rod-shaped part is provided on one of the holding part and the part to be held, and a hole to which the rod-shaped part is fitted is formed in a remaining one of the holding part and the part to be held.
8 . The medical system according to claim 1 , wherein the part to be held has a plurality of projection-stripe portions, and the plurality of projection-stripe portions extend in parallel to one another in a longitudinal axial direction of the device.
9 . The medical system according to claim 1 , wherein the part to be held has a plurality of conical-shaped portions having apexes capable of coming in contact with the holding part.
10 . The medical system according to claim 1 , wherein the insertion part has an external tube and a device channel formed in the external tube, and the device has a flexible tube part insertable into the device channel.
11 . An operation method of a device disposed in an inside of a body, wherein a part of the device is held using a holding part provided on an arm part that is the body provided separately from the device and has at least one degree of freedom, and the arm part is moved, so that the device held by the holding part is moved together with the arm part.
