Abstract:
1. A treatment tool which is configured to be used with an endoscope and is inserted into a body cavity for use, comprising: a wire shaped manipulation member having a treatment part with a distal end thereof which is configured to perform a treatment procedure to a subject by applying thermal energy to the subject; a tubular shaped sheath composed of thermoplastic resin having an insertion path; a manipulation part attached to a proximal end of the manipulation member so as to move the treatment part with respect to the sheath in order to perform the treatment procedure; wherein the sheath is configured such that the manipulation member is inserted into the insertion path and that the treatment part protrudes from a distal end of the sheath, the distal end of the sheath including: a crosslinked part, at a more distal end side of the sheath than the noncrosslinked part, formed by crosslinking the thermoplastic resin of a contact part which is contacted by the treatment part, said crosslinked part protruding from the distal end of the sheath, when the treatment procedure is performed by the treatment part.
