Abstract
Abstract A treating instrument erecting device for use in an endoscope includes a treating instrument erecting member for changing the direction of projection of the distal end portion of a treating instrument inserted in a treating instrument inserting channel. The treating instrument erecting member is provided at the distal end of an insert part of the endoscope. A control wire for operating the treating instrument erecting member is axially movably inserted in a wire guide provided in the insert part to extend over the entire length of the insert part. A wire driving member for advancing or retracting the control wire is provided in a control part connected to the proximal end of the insert part. The control wire and the wire driving member are electrically isolated from each other.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
138 words
A treating instrument erecting device for use in an endoscope, comprising: a treating instrument erecting member for changing a direction of projection of a distal end portion of a treating instrument inserted in a treating instrument inserting channel, said treating instrument erecting member being provided at a distal end of an insert part of said endoscope; a control wire for operating said treating instrument erecting member, said control wire being axially movably inserted in a wire guide provided in said insert part to extend over an entire length of said insert part; and a wire driving member for advancing or retracting said control wire, said wire driving member being provided in a control part connected to a proximal end of said insert part; wherein said control wire and said wire driving member are electrically isolated from each other.
Claim 2
Dependent Claim
138 words
A treating instrument erecting device for use in an endoscope, comprising: a treating instrument erecting member for changing a direction of projection of a distal end portion of a treating instrument inserted in a treating instrument inserting channel, said treating instrument erecting member being provided at a distal end of an insert part of said endoscope; a control wire for operating said treating instrument erecting member, said control wire being axially movably inserted in a wire guide provided in said insert part to extend over an entire length of said insert part; and a wire driving member for advancing or retracting said control wire, said wire driving member being provided in a control part connected to a proximal end of said insert part; wherein said control wire and said wire driving member are electrically isolated from each other.
Claim 3
Dependent Claim
26 words
A treating instrument erecting device according to claim 1 , wherein said control wire is covered with an electrically insulating coating over an entire length thereof.
Claim 4
Dependent Claim
48 words
