Endoscope apparatus
First Claim
1. An insertion shape detection probe comprises:
- an elongated core wire to which a plurality of shape detection elements with signal lines extending therefrom are fixed at prescribed intervals;
a plurality of inner sheaths provided on the proximal end sides of the shape detection elements fixed to the core wire and having said core wire and said signal lines passed therethrough;
linking and fixing means for covering and integrally linking said shape detection elements and inner sheaths adjacent to the shape detection elements; and
an outer sheath having inserted therein said plurality of shape detection elements and said plurality of inner sheaths integrated with said core wire.

Abstract
An endoscope apparatus comprises an endoscope having a treatment tool passage channel in at least an insertion portion, an adaptor for endoscope forceps opening, which can be detachably attached to a treatment tool insertion opening which is at one end of the treatment tool passage channel, an insertion shape detection probe provided with a plurality of shape detection elements which are to be passed and arranged in the treatment tool passage channel via the adaptor for endoscope forceps opening, an insertion shape detection unit for detecting magnetic field emitted from the shape detection elements of the insertion shape detection probe, an insertion shape detection device which drives the insertion shape detection probe and outputs video signals for visualizing the insertion shape from the signals corresponding to the magnetic field detected by the insertion shape detection unit, and a display device for displaying the insertion shape of the insertion portion based on the video signals output from the insertion shape detection device.

15. An insertion portion detection probe comprises:
-
an elongated core wire;
a plurality of shape detection elements that have an axial through hole through which the core wire is passed and are adhesively fixed to said core wire at prescribed intervals;
signal lines connected to those shape detection elements and extended to the proximal end side along said core wire;
an inner sheath covering the signal lines extending along said core wire and having at least one end surface facing the end surface of said shape detection elements; and
an outer sheath covering the inner sheath and said plurality of shape detection elements.

16. An adaptor for endoscope forceps opening comprises:
-
an adaptor linking member that can be detachably attached to the endoscope forceps opening communicated with the treatment tool passage channel through which the treatment tool is to be passed;
a treatment tool integration member which is in tight contact with and fixed to part of the treatment tool protruding from said endoscope forceps opening; and
a treatment tool position changing member for changing stepwise, together with the treatment tool integration member, the insertion position of the treatment tool in a state in which said treatment tool integration member is in tight contact therewith. - View Dependent Claims (19)

17. An adaptor for endoscope forceps opening comprises:
-
a tubular adaptor linking member having a mounting portion that can be detachably attached to an endoscope plug provided in the endoscope forceps opening through which the treatment tool is to be passed;
a treatment tool integration member having a tubular shape and elastic properties and arranged in a prescribed position of the adaptor linking member;
a pressing member arranged so that it is free to advance and retreat with respect to said adaptor linking member and used to apply a pressure with a prescribed force to said treatment tool integration member for elastic deformation thereof, thereby causing the treatment tool integration member to be brought in intimate contact with and fixed to part of said treatment tool; and
a treatment tool position changing member which has a tubular shape, comprises a mounting portion that can be detachably attached to said forceps plug and a notched portion communicated with the axial through hole, and is arranged so that it can be detachably attached to the distal end side of said adaptor linking member.

18. An adaptor for endoscope forceps opening comprises:
-
an adaptor linking member which can be detachably attached to a forceps socket constituting the endoscope forceps opening through which the treatment tool is to be passed and is composed of a first socket fixing member arranged on the outer peripheral side of the forceps socket and a second socket fixing member in which a positioning pin is provided in a protruding condition from a prescribed position on the outer peripheral surface which is integrally fixed to the first socket fixing member in a state where the second socket fixing member is abutted against the distal end side of said forceps socket;
a treatment tool position changing member which is arranged so as to be free to advance and retreat with respect to said adaptor linking member and has formed therein a motion-control groove that can move along said positioning pin and can be retained by the positioning pin;
a treatment tool integration member having a tubular shape and elastic properties and arranged in a prescribed position of the treatment tool position changing member; and
a pressing member arranged so as to be free to advance and retreat with respect to said tool position changing member and used to apply a pressure with a prescribed force to said treatment tool integration member for elastic deformation thereof, thereby causing the treatment tool integration member to be brought in intimate contact with and fixed to part of said treatment tool.
