Abstract
A forceps includes a flexible sheath which is to be inserted into the insertion channel of an endoscope. Sampling cups are fitted to the distal end of the sheath. A control wire is movably inserted into the sheath and connected at one end to the cups. The other end of the control wire is fitted with a control section arranged at the proximal end of the sheath. The control section effects the push and pull of the control wire, thereby opening and closing the cups. That portion of the wire which lies near to the control section is impregnated with a hardening agent to provide a hardened section.
