Endoscopic manipulating wire coupling structure
First Claim
1. An endoscopic manipulating wire coupling structure in which an end of a manipulating wire formed of two or more twisted strands is inserted into an opening in a mating member which is plastically deformed from the outer circumference inward so that it is securely pressed against said manipulating wire,wherein at least that portion of said mating member which is fitted over said manipulating wire is formed of a material softer than said manipulating wire.

Abstract
An endoscopic manipulating wire coupling structure is constructed such that an end of a manipulating wire including two or more twisted strands is inserted into an opening in a mating member which is plastically deformed from the outer circumference inward so that it is securely pressed against the manipulating wire. At least that portion of the mating member which is fitted over the manipulating wire is formed of a material softer than the manipulating wire.

6. An endoscopic manipulating wire coupling method comprising the steps of:
-
fitting a portion of a mating member over an end portion of a manipulating wire formed of two or more twisted strands, said portion of the mating member being softer than said end portion of the manipulating wire;
applying pressure onto the outer circumference of said portion of the mating member to cause plastic deformation of said portion of the mating member and elastic deformation of said end portion of the manipulating wire but not to cause plastic deformation of said manipulating wire. - View Dependent Claims (7, 8, 9, 10)
interposing a tubular member between said portion of the mating member and said end portion of the manipulating wire prior to said step of applying pressure, the tubular member being softer than the manipulating wire.

9. The endoscopic manipulating wire coupling method according to claim 6, further comprising:
providing a tubular member on and around said end portion of the manipulating wire prior to said step of fitting, the tubular member being softer than the manipulating wire.
-
10. The endoscopic manipulating wire coupling method according to claim 6, further comprising:
providing a tubular member on and around an interior of said portion of the mating member prior to said step of fitting, the tubular member being softer than the manipulating wire.
