Problems solved by technology

If one hand is used to operate the French bender, the physician must rotate that hand in an awkward position to properly view the bar curve as the handles are squeezed together, and the physician's awkward position with one hand may prevent Physician applies the appropriate amount of force needed to bend the rod or cause slippage of the instrument
As a result, many physicians use two hands to operate the French bender, which prevents the physician from using the free hand to manipulate the bars (or other manual activities) in the French bender

Embodiment Construction

[0087] Figure 1 to Figure 6 A spinal rod bending instrument 10 (hereinafter instrument) according to an exemplary embodiment of the present invention is shown. Referring generally to the features of the instrument 10, the instrument 10 includes a handle 12 (having a handle grip portion and a handle actuator portion) and a lever 14 (having a lever grip portion and a lever actuator portion) A pin 16 in the actuator portion and lever actuator portion is pivotally mounted to the handle 12 . The pin 17 is mounted to the handle 12 (in the handle actuator portion of the handle 12) and to a slot or recess 19 formed in the lever 14 (in the lever actuator portion of the lever 14) towards the handle grip at the lever grip portion In the case of partial pivoting, this slot or recess 19 abuts against the pin 17 to limit the pivoting movement of the lever 14 . The pawl 18 is pivotably mounted on the crescent-shaped recess 20 ( Figure 4 ), the crescent-shaped recess 20 is formed in the ...

Abstract

An instrument for bending a surgical implant about a bending axis includes a handle defining a receiving area for receiving the surgical implant. A lever is pivotably connected to the handle about a pivot axis that can be orthogonal to the bending axis. A movable linkage can be connected to the lever for movement with the lever. The moveable linkage can be configured to bend the surgical implant about the bending axis upon pivoting the lever about the pivot axis.

Description

technical field [0001] The field of the invention relates generally to an instrument for bending a spinal fixation rod. Background technique [0002] As disclosed in US Patent No. 7,454,939, spinal fixation systems may be used in surgery to align, adjust and / or fix portions of the spine, ie, vertebrae, in a desired spatial relationship relative to each other. Many spinal fixation systems employ spinal fixation rods to support the spine and properly position components of the spine for various therapeutic purposes. Spinal rods, usually formed of metals such as stainless steel or titanium, may be implanted to correct deformities, prevent movement of the vertebral bodies relative to each other, or for other purposes. Vertebral anchors, including pins, bolts, screws, and hooks, engage vertebrae and connect rods to different vertebrae. [0003] Spinal fixation rods are often oriented at various angles and positions due to the patient's anatomy, the physiological problem being t...
