A single-patient-use disposable tool comprises a molded, single-piece body with a curved upper surface having a predetermined bend radius for bending a needle slidably disposed in a sheath. A distal end of the curved surface has a slot for insertion of a tip of a needle, while the proximal end of the curved surface has a guide member for slidably receiving the sheath. Two finger loops or similar ergonomic features allow the user to rotate the bending tool relative to the sheath to bend the needle about the predetermined bend radius. After completing the bend, the tool is removed from the needle and disposed of.

Disclosed are differential temperature push bending method and device for tube with small bending radius, the device comprising: a push bending die, core, fillers and pushers, wherein the core and the fillers are both arranged in a bending chamber of the push bending die, an inlet and an outlet end of the push bending die are respectively provided with a front guiding sleeve and a rear guiding sleeve, the pusher in the front guiding sleeve abuts against a plurality of fillers, and the pusher in the rear guide sleeve abuts against the core. A heat rod is provided at an outer end of the bending chamber. The present disclosure adopts differential temperature type push bending, flow performance of the tube blank at the outer corner of the die can be improved, and the material can be timely fed to prevent excessive stretching and thinning of the outer material.

A tube bender is provided, including: a fixation portion, configured to be held by a fixation base; a plurality of bending portions, connected with the fixation portion, each of the plurality of bending portions has a circumferential guiding face, at least two of curvature of radiuses of the circumferential guiding faces of the plurality of bending portions are different.

The purpose of the present invention is to provide a method for producing a pipe material and to provide a mandrel with which resistance between a member to be processed and the mandrel during bending processing can be reduced and overall processing time can be shortened. The method for producing a pipe material includes: a step for inserting a mandrel, which is provided on the inside thereof with a flow path through which dry ice powder flows and spray holes at the tip thereof for spraying the dry ice powder, inside pipe material; a step for spraying the dry ice powder from the spray holes inside the pipe material; and a step for performing bending processing on the pipe material wherein the mandrel has been inserted.

Benders are disclosed relating to the convenient, accurate, and precise bending of tubing. Example benders include features such as a mandrel, adjustable mechanical stops, and scales having relatively high resolution along with significant distance from a central axis of the mandrel. Certain benders may include separate fine and course adjustments to bend angles and support mechanisms for controlling the bend plane angle.
