A bender tool measuring system includes a conduit bender, a bent piece of conduit, and a measurement apparatus coupled to the conduit. The conduit bender includes a bender head comprising a hook and a handle coupled to and extending from the bender head. The measurement apparatus is configured to project an optical projection onto the handle of the conduit bender, and the location of the optical projection on the length of the handle indicates the position of the bent piece of conduit in relation to the bender head.

Devices and methods for bending or cutting implants are disclosed herein. In some embodiments, an instrument can convert a rotational input force (e.g., supplied by a powered driver tool) into movement of a first rod holder with respect to a second rod holder. Such movement can form a bend in a rod or other implant held by the first and second rod holders. Various mechanisms for converting this movement are disclosed, such as a worm drive mechanism and a conical gear mechanism, as are various types of rod holders, including orbiting rollers, lid-type rod holders, fixed and pivoting half-pipe rod holders, and full-pipe rod holders. In some embodiments, the instrument can also be used for cutting, for example by rotating a cutting wheel with respect to a cutting plate to cut a rod or other implant inserted through openings formed in the cutting wheel and the cutting plate.

A digitizer pointer is provided as part of a system for correcting a curvature or deformity in a patient's spine based on the digitized locations of implanted screws and tracking the placement of the rod as it is placed in a minimally invasive fashion. The digitizer pointer includes an offset adjustment feature, a swivel feature, and a translation feature.

A tool, such as a conduit bender, that includes a gear assembly for providing a mechanical advantage when bending a workpiece conduit. The gear assembly comprises a pinion gear rotatably coupled to a handle, the handle including a pin that can be selectively engaged with the pinion gear. The conduit bender also includes a shoe with teeth that protrude radially inward from a curved outer portion. When the conduit bender is in use, the teeth of the pinion gear engage with the teeth of the shoe.

A hollow stabilizer includes a curved part having eight regions defined in a cross section. A first region includes a 90° first part when the center of the inside of the curve is taken to be at 0° and the center of the outside of the curve is taken to be at 180°. A third region includes a 0° third part. A fifth region includes a 270° fifth part. A seventh region includes a 180° seventh part. The radii of curvature of the respective outer surfaces of the third part and the seventh part are larger and the radii of curvature of the respective outer surfaces of the second part and the sixth part are smaller than the radii of curvature of the respective outer surfaces of the fourth part and the fifth part.

One aspect of the present disclosure is a manufacturing device by which the bent pipe is obtained by bending a double pipe. The device includes inner and intermediate core metals, a bending mold, and a controller. The controller executes: a first bending process in which first and second pipes are bent by the bending mold in a first direction in a first area of the double pipe where the inner and intermediate core metals are placed; a second bending process in which the first and second pipes are bent, after the first bending process, by the bending mold in a second direction in a second area of the double pipe where the inner and intermediate core metals are placed; and a first bending-back process in which the second pipe is bent, after the first bending process, in a direction opposite to the first direction in the first area.
