Abstract: There is disclosed a treatment device for an endoscope, comprising a treatment portion in which an operation wire is forward/backward moveably inserted into a main tube of an elongated flexible tube to be inserted into a body, a tip end of the operation wire forms a loop for treatment by itself in a projection state from the main tube, and the loop is adapted to be retractable and storable in the main tube, wherein the treatment portion is formed with a wire rope obtained by integrally intertwining a plurality of side strand wires with a core strand wire, and spiral convex or concave portions continuously disposed along the outer periphery of the wire rope are formed with the side strand wires.

Abstract: In a medical treatment tool (1, 1A, 1B), a flexible linear wire forms a main linear wire portion (2) provided by a wire-stranded helical hollow tube (6) coated with an outer protective layer (8). An operational core elongation (4) is slidably inserted into the main linear wire portion (2) of the wire-stranded helical hollow tube (6). A front end of the main linear wire portion (2) is connected to a front end of the operational core elongation (4), and a rear end of the operational core elongation (4) is connected to a hand access portion (5) placed at a rear end of the main linear wire portion (2). A diametrically expandable portion (3) is formed at a distal end portion of the main linear wire portion (2) by exposing the wire-stranded helical hollow tube (6) outside from the outer protective layer (8).

Abstract: A driving rope for use with the printing head carriage of a word processor, a plotter or other compact equipment. The driving rope generally comprises a core rope and a thread formation of resin disposed thereon. Unlike a conventional timing belt, this driving rope is deformable for easy routing and yet assures a positive and accurate shift of the carriage.
