Abstract: A coiling machine includes feed rollers for moving a wire, a wire guide, a first forming roller, a second forming roller, a pitch tool, a cutting mechanism, and a support mechanism for supporting the wire. The cutting mechanism includes a cutting rotor. The wire coming out of the wire guide is formed into a helical shape by the first forming roller, the second forming roller and the pitch tool. After one coil spring of a predetermined length is formed, the wire is cut by moving the cutting rotor in the radial direction of the wire. The cutting rotor cuts the wire supported by the support mechanism in the radial direction of the wire between the second forming roller and the pitch tool.

Abstract: An endoscope treatment tool, comprising: a sheath; a handle body; a wire; a treatment portion connected to a distal end of the wire and arranged on a distal end side of the sheath; a rotating handle movable with respect to the handle body and connected to the wire; a conductive connector having an insertion passage through which the wire is inserted, wherein the wire is movable in a wire movement direction to advance and retreat in a direction that is parallel to a longitudinal axis of the handle body, wherein the wire is rotatable around an axis of the wire movement direction, and wherein the conductive connector extends in a direction that intersects the wire movement direction.

Abstract: A pump unit and a pump capable of detecting characteristics of a conveyance article and a method for detecting the characteristics of the conveyance article. A pump unit includes an outer cylinder; an inner cylinder disposed on an inner circumference side of the outer cylinder; and a pressure supply chamber provided between the inner cylinder and the outer cylinder, the pump unit being configured to convey a conveyance article in the inner cylinder by supplying a pressurizing medium into the pressure supply chamber and thereby causing the inner cylinder to expand inwardly in a radial direction, in which the pump unit further includes a conveyance article information acquiring device configured to acquire information on the conveyance article in the inner cylinder at a time when the inner cylinder is expanded.
