System and method for automatically bending a surgical rod are provided. The system includes a linear movement device configured to axially feed the surgical rod, a rotational movement device configured to rotate the surgical rod as it is axially fed, and a bending device including a roller to impose bending forces against the rod. The rod is free from contact with the bending device after it is axially fed past the roller.

A device for bending wire includes a first plate with upper and lower surfaces and a center aperture extending therebetween. A cavity is formed in the upper surface that includes opposing sidewalls with a separation that decreases as they extend towards the center aperture and decreases as they extend up from a bottom surface of the cavity. A pin assembly disposed in the cavity includes a second plate having a pin extending from a top surface and having opposing side surfaces with a separation that decreases as they extend towards the center aperture and decreases as they extend up toward the top surface. A shaft extends through the center aperture and terminates in a bend head having a wire aperture and first and second bend surfaces adjacent the wire aperture. A first motor is configured to rotate the first plate about the shaft in opposing first and second rotational directions.

A device for bending wire that includes a pin extending from an upper surface of a plate, a shaft extending through a center aperture of the plate and terminating in a bend head, a sleeve rotatably disposed around the shaft, a first motor for rotating the plate about the shaft, and a second motor configured to move the plate between extended, retracted and intermediate positions along the shaft. The plate positioned in the extended position and rotating causes the first pin to travel in front of a wire aperture of the bend head. The plate positioned in the intermediate and the retracted positions and rotating causes the first pin to travel underneath the wire aperture. The plate positioned in the retracted position causes the plate to engage with the sleeve such that rotation of the plate causes rotation of the sleeve.

A wire forming press apparatus includes a press having a die assembly including a displaceable upper die moved with respect to a fixed lower die. A first lever arm is manually displaced to perform a first operation in a first direction on a wire blank positioned between the upper die and the lower die. A second lever arm is manually displaced to perform a second operation in a second direction opposite to the first direction on the wire blank. A first gear set is connected to and rotated by displacement of the first lever arm. A second gear set is connected to and is rotated by displacement of the second lever arm.

A needle bender for custom bending of needles to different desired needle bend radii is provided. The needle bender can include abase and a shaper coupled to the base through a support member. The shaper may have a plurality of grooves corresponding to different desired needle bend radii. A leverage arm with a needle slide disposed on one end may be rotatably coupled to the support arm. When a needle is inserted along the base into one of the grooves in the shaper and at least partially into the needle slide, the leverage arm can be actuated toward the base to thereby bend the needle to the desired needle bend radius. The needle bender may also include a lock plate between the base and the shaper that can be actuated toward the shaper to further secure the needle to the shaper.

A wire feeding unit includes a driving motor; a driving roller which rotates by a driving force of the driving motor; a plurality of driven rollers arranged such that outer circumferential surfaces thereof are positioned on a same line; a belt which interlocks the driving roller and the plurality of driven rollers and is brought into contact with a wire, which is drawn into a side of the driven rollers, on a side of the plurality of driven rollers; and a plurality of idlers which support the wire on a side in which the wire and the belt are in contact with each other and assist feeding of the wire along a feeding direction of the belt in a free-rotation state.

Provided herein are devices, systems, and methods for bending a needle. More particularly, the present disclosure provides materials and methods relating to bending the distal end of a needle with more precision than conventional means, which improves the performance of various medical procedures and leads to better patient outcomes.

A system and method for bending a surgical rod using an automated bending system includes receiving an indication of a plurality of line segments defined on the rod and an indication of an angle measurement to be formed between at least two adjacent ones of the plurality of line segments. Bending parameters to perform on the rod to form the angle measurement between the at least two adjacent ones of the plurality of line segments are determined and operation of the automated bending system is controlled using the bending parameters to create an angle having the angle measurement between the at least two adjacent ones of the plurality of line segments.
