Body cavity diagnostic apparatus

A body cavity diagnostic apparatus comprising:

• an insert portion which is inserted into a body cavity;
• an operating portion;
• a wire extending from the forward end of said insert portion to said operating portion so as to be bent in a predetermined direction by a wire-pulling means in said operating portion;
• and an insulating member for connecting an electrically conductive base plate for a support shaft of said wire-pulling means of said operating portion with an electrically conductive structural member of said insert portion.

A body cavity diagnostic apparatus comprising:

• an insert portion which is inserted into a body cavity;
• and operating portion;
• wires having heads extending from the forward end portion of said insert portion to said operating portion so as to be bent in a predetermined direction by a wire-pulling operation of said operating portion;
• and a joint member of an insulating material for connecting at least one of said wires with said operating portion and said forward end portion by said joint member holding the head of one of said wires so as to electrically isolate said operating portion from said forward end portion.

A body cavity diagnostic apparatus comprising in combination:

• a main body;
• an inner electrically insulating cover made of an elastic rubber material;
• an outer electrically insulating cover made of synthetic resin;
• metal members having outsides and which constitute a structural part of said main body;
• wherein said inner and outer insulating covers are connected in such a manner as to overlap each other on said metal member outsides;
• said apparatus further comprising a bent portion connected to an insert portion, a control portion, and a connecting portion for said insert and control portions,
• wherein said inner and outer insulating covers and said annular airtight member are applied to said connecting portion for an operating portion and said bent portion connected to an insert portion which is inserted into a cavity of an object of inspection;
• an annular airtight member which is disposed between said insulating covers;
• an insert portion which is inserted into a body cavity;
• an operating portion;
• a wire extending from a forward end of said insert portion to said operating portion so as to be bent in a predetermined direction by a wire-pulling means in said operating portion;
• an insulating member for connecting an electrically conductive base plate for support shaft of said wire-pulling means of said operating portion with an electrically conductive structural member of said insert portion;
• wires having heads extending from the forward end portion of said insert portion to said operating portion so as to be bent in a predetermined direction by a wire-pulling operation of said operating portion;
• and
• a joint member of an insulating member for connecting at least one of said wire wires with said operating portion and said forward end portion by said joint member holding the head of one of said wires so as to electrically isolate said operating portion from said forward end portion.
