BASKET TYPE GRASPING FORCEPS

摘要

Basket type grasping forceps include a sheath, a main body section, and a manipulation section, the main body section includes a basket section and a manipulation wire, the basket section includes a plurality of basket wires and a distal fixing member fixed to the plurality of basket wires, and the distal fixing member has a wire-fixing section to which a first wire serving which is at least one of the plurality of basket wires is fixed, and a high-strength fixing section to which a second wire which is at least another one of the plurality of basket wires is fixed more strongly than a fixing strength of the first wire in the wire-fixing section.

1. Basket type grasping forceps, comprising:
a sheath; a main body section having a distal end and a proximal end and being inserted through the sheath; and a manipulation section fixed to the sheath and at which the proximal end of the main body section is disposed, wherein the main body section comprises: a basket section disposed at the distal end side of the main body section and configured to hold foreign substances; and a manipulation wire disposed at a proximal end side of the basket section and fixed to the basket section, wherein the basket section comprises: a plurality of basket wires disposed to form a basket shape to hold the foreign substances therein; and a distal fixing member fixed to the plurality of basket wires at a distal end portion of the basket section, and the distal fixing member has a wire-fixing section to which a first wire which is at least one of the plurality of basket wires is fixed, and a high-strength fixing section to which a second wire which is at least another one of the plurality of basket wires is fixed more strongly than a fixing strength of the first wire in the wire-fixing section, the basket section further comprises a center wire extending from a distal end of the basket section toward a proximal side of the basket section; and the distal fixing member further includes: a first distal fixing member fixed to the basket wire and disposed at a distal side of the basket section; and a second distal fixing member having the high-strength fixing section and disposed at a distal side of the first distal fixing member, at least one of the plurality of basket wires are fixed to the high-strength fixing section, the second distal fixing member being fixed to a distal end of the center wire.
