In-vivo monitoring camera system
An in-vivo monitoring camera system includes an image capturing portion (camera unit 11 ) that is capable of being introduced into a body, a support tube ( 13 ) that has a connection portion (trocar connection portion 13 x ) with a tubular tool (trocar 31 ) which is capable of being introduced into the body on one end side and has a joining portion (protrusion type joining portion 13 y ) to the image capturing portion on another end side, a cable (camera-side cable 12 ) that is connected with the image capturing portion and passes through the support tube, and a control system that is electrically connected with the cable and includes at least a display device ( 18 ).
1. An in-vivo monitoring camera system comprising:
an image capturing portion that is capable of being introduced into a body;
a support tube that has a connection portion with a tubular tool which is capable of being introduced into the body on one end side and has a joining portion to the image capturing portion on another end side;
a cable that is connected with the image capturing portion and passes through the support tube; and
a control system that is electrically connected with the cable, wherein
an outer surface of the connection portion is connected with the tubular tool, the outer surface of the connection portion having a tapered shape,
the support tube has a root portion between the connection portion and the joining portion, and
the root portion is in a tapered shape that becomes thinner in a direction to approach the joining portion.
2. An in-vivo monitoring camera system comprising:
an image capturing portion that is capable of being introduced into a body;
a support tube that has a connection portion with a tubular tool which is capable of being introduced into the body on one end side and has a joining portion to the image capturing portion on another end side;
a cable that is connected with the image capturing portion and passes through the support tube; and
a control system that is electrically connected with the cable, wherein
an outer surface of the connection portion is connected with the tubular tool, the outer surface of the connection portion having a tapered shape, and
the support tube includes a core tube and an attachment that has an insertion hole through which the core tube is placed and that is mounted on an outside surface of the core tube.
3. The in-vivo monitoring camera system according to claim 2 , wherein the joining portion is provided on one end side of the core tube, and the connection portion is provided to the attachment.
4. The in-vivo monitoring camera system according to claim 2 , wherein the attachment is in a spindle shape.
5. The in-vivo monitoring camera system according to claim 2 , wherein
the cable has a connector on an opposite side to a connection end with the image capturing portion, and
the attachment is configured such that the connector is capable of being placed through an inside of the insertion hole.
6. The in-vivo monitoring camera system according to claim 2 , wherein a material with thermal conductivity is used for the core tube.
7. The in-vivo monitoring camera system according to claim 2 , wherein an insulating material is used for the attachment.
8. The in-vivo monitoring camera system according to claim 2 , wherein a slit is formed in the core tube.
9. The in-vivo monitoring camera system according to claim 2 , wherein a fitting force between the core tube and the attachment is greater than a joining force between the image capturing portion and the support tube.
