An assembly for bending a conduit and a portable conduit bender. The assembly may generally include a portable bender including a base having a base surface supportable on a work surface, a housing supported by the base and defining a housing axis, the housing including a handle engageable by an operator to carry the bender, and a shoe supported by the housing for pivoting movement about the housing axis, the shoe defining a channel for supporting a conduit to be bent; and a pipe threader removably supported by the housing, the threader being operable to pivotably drive the shoe relative to the housing to bend the conduit.

An automatic machine for producing reinforcement blanks, in particular of the type of reinforcement chairs, the automatic machine comprising two outer moulding units (A, A′) and two inner moulding units (B, B′), wherein each of the moulding units (A, A′ and B, B′) comprises a pair of mandrels—a movable mandrel (8, 5) and a stationary mandrel (7, 6) connected to a power mechanism (11, 2). A method for producing reinforcement chairs from reinforcement sections comprising simultaneously forming the two support legs of the reinforcement chair in mutually opposite directions by the two outer moulding units (A, A′) and then simultaneously forming the two vertical supports of the reinforcement chair by the two inner moulding units (B, B′).

A system for rod bending for use in robotic spinal surgery, enabling the correct bending of a fusion rod to match the shape required to accurately pass through the heads of the pedicle screws. The system uses data generated by information provided to the robot by the surgeon's preoperative plan, optionally augmented by feedback from the robot control system of deviations encountered intraoperatively. Such deviations could occur, for example, when the surgeon decides intraoperatively on a different trajectory or even to skip screws on one vertebra, in which case, the robot will be commanded to perform the alternative procedure, with commensurate instructions relayed to the control system of the rod-bending machine. The system is also able to thin down the rod at predetermined locations along its length, adapted to be at selected intervertebral locations, for maintaining limited flexibility between vertebrae, instead of fixating them.

Provided is a method of automatically forming a pipe, the method including inputting a design file to a program for automatically extracting information for forming a pipe, automatically extracting, from the design file, information about a cutting point for dividing a pipe included in the design file into a plurality of pipes and information about a bending point of each of the plurality of pipes, and transmitting, to a forming device for forming the pipe, pipe forming information including the cutting point and the bending point.

A compact, lightweight, portable tubing bender configured to enable one-handed operation. The tubing bender includes a portable housing including a handle portion, a bender shoe operably coupled to the portable housing, the bender shoe defining an arcuate channel configured to restrain a length of tubing along a prescribed arc during bending operations, a guide gear fixedly coupled to the bender shoe, and a guide frame pivotably coupled to the bender shoe, the guide frame including a motor, a driven gear and a guide member, the motor configured to drive the driven gear along the guide gear to pivot the guide frame relative to the bender shoe, so as to move the guide member during bending operations to guide the length of tubing along the arcuate channel of the bender shoe.
