Abstract
A handling section for an endoscopic treatment tool that permits the manipulation stroke of a manipulating wire to be set or changed to an optimal condition in an easy way. Tubular stopper (8) for restricting the range over which manipulating members (13, 15) are moved in a direction in which manipulating wire members (3, 3a) are pushed into flexible sheath (1) is formed of a nonmetallic material that can be cut with a cutter and loosely fitted over manipulating wire members 3 and 3a as it is detachably mounted to the basal end portion of flexible sheath (1).
Claims7
A handling section connectable to an endoscopic treatment tool having a flexible sheath and a manipulating wire member passed through the flexible sheath axially movably, the handling section comprising:
- a main body to which a basal end of the flexible sheath is detachably coupled;
- a manipulating member to which a basal end of the manipulating wire member is detachably coupled, the manipulating member being movably arranged on the main body to axially move the manipulating wire member relative to the flexible sheath;
- and
- a tubular stopper detachably coupled to the basal end of the flexible sheath and fitted over the manipulating wire member, the tubular stopper restricting a range over which the manipulating member is moved in a direction in which the manipulating wire member is pushed into said flexible sheath.

- and
- a tubular stopper detachably coupled to the basal end of the flexible sheath and fitted over the manipulating wire member, wherein an end face of the tubular stopper, which is located opposite from the basal end of the flexible sheath, is contactable with the manipulating member to restrict movement of the manipulating member.
