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 tool for bending cable comprising a web forming a base having an upper surface, a lower surface, first edge, second edge, a first area of the base defining a bend member portion and a second area of the base defining a hand hold portion. The tool further comprising a set of wire gauge measuring intervals is integral with the first edge in the second area. The tool further comprising a set of bend members is arranged in a raised diminishing hierarchy on the upper surface in the first area, forming a cable bend radius gauge.

A dual size conduit bender preferably includes a base member, an upper pole support member, a foot support member and a conduit support member. Opposing ends of the upper pole support member extend from a top of the base member. A pole boss extends upward from a top of the base member. The foot support member extends upward from one end of the base member. The conduit support member extends from an opposing end of the base member. First and second curved grooves are formed in a bottom of the base member. A pair of clearance slots are formed in an end of the foot support member. A pair of insertion slots are formed in a top of the conduit support member. A pole bore is formed through a top of the upper pole support member into the pole boss to receive a bending pole.

The present invention relates to an automatic bending apparatus for a copper pipe connector that is capable of bending the copper pipe connector through a single operation, and the automatic bending apparatus includes: a body movably placed on a floor; a supply part located on a side portion of the body to supply the copper pipe connector to be bent; a bending position adjusting part located on top of the body to allow the copper pipe connector supplied from the supply part to be placed at an accurate bending position; a first bending part and a second bending part located on top of the body to face each other and adapted to bend the copper pipe connector; and a controller located above the side portion of the body to control operations of the respective parts.

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.

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 method of bending a conduit is disclosed. An engagement member is displaced via contact with the conduit and engages a switch. A signal is sent to a microprocessor indicative of a characteristic of the conduit to be bent, in response to engagement of the switch. The microprocessor provides a motor control signal to the motor to control a rotation of the shoe, wherein rotation of the shoe bends the conduit.

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 conduit bender having a unitary frame is mounted to a wheeled base which provides for transportation of the bender. A braking assembly provides for simplified locking of the wheels to secure the bender in a location. The bender is mounted to the base through a pivoting assembly which allows for bending of conduit in either a horizontal or vertical plane. A circuit is provided for controlling the bending operation. An auto-sensing portion of the circuit receives information regarding the characteristics of the conduit to be bent upon placement of the conduit in the bender. A feedback portion of the circuit is used to provide a precise bending operation.

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.
