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 is includes an offset adjustment feature, a swivel feature, and a translation feature.

A needle bending assembly configured to at least temporarily contain a needle can include a first housing section, a second housing section, and a coupling element coupled between the first housing section and the second housing section. The first housing section defines a first cavity configured to at least temporarily contain a first section of the needle. The second housing section defines a second cavity configured to at least temporarily contain a second section of the needle forming a distal tip. The coupling element is configured such that when the needle is contained within the housing sections, movement of the second housing section relative to the first housing section results in a bending of the needle at a location corresponding to the coupling element.

A bender includes a rotatable bending shoe having at least one channel therein configured to receive a workpiece, a seat proximate to the bending shoe which is configured to receive the workpiece thereon, and a sensor provided on the seat which is configured to sense the presence of the workpiece. In some embodiments, the sensor is configured to sense an end of the workpiece.

A single bending device for continuous three-dimensional bending has a rotating and feeding holder for holding a workpiece, a bending roller assembly having multiple rollers being different in radius, a pressing roller head for bending the workpiece. The bending roller assembly can be moved to allow one predetermined roller to abut against the workpiece. Then the workpiece can be bent by the pressing roller head pushing the workpiece along the predetermined roller. Thus, as long as a different one of the rollers corresponds in position to the workpiece, a bending portion having a different curvature can be formed on the workpiece. Moreover, by controlling the moving length of the pressing roller head along the workpiece, the arc length of each bending portion of the workpiece can be controlled accordingly. It is not necessary to replace the jigs and the dies repeatedly.

A hydraulically operated rotary pipe bending machine has a box (1) from which superiorly protrude a die shaft (2) that is rigidly connected to a die and integral with a die gear (29) being driven by an actuator (30) through a hydraulic circuit and being stopped by a limit switch device (8), and a counter-die unit (3) driven by a handwheel (4) in order to place an elongated piece to be bent against said die. The actuator (30) has a single-acting cylinder, having a piston (31) holding a rack rod (30a) engaging said die gear (29), the piston (31) being opposed in its travel by a return spring (33). The limit switch device (8) has an angularly graduated disc (10) mounted, manually adjustable, on the die shaft (2) and provided with a cam (16) designed to control said limit switch (17) of the hydraulic circuit.

Disclosed is a tube bending device which includes at least one bending roller mounted to be rotatably movable relative to a frame and at least one crease erasing member. This device is specific in that it includes a plate designed with: reception surfaces to receive, support and position the crease erasing member which is attached thereto, a unit for fixing to the frame, and guide surfaces pivotably connected for the roller.
