Abstract

An apparatus and a method are provided for a surgical bending instrument for bending surgical implants. The surgical bending instrument comprises a body including a longitudinally extending threaded hole. A shaft comprising a threaded portion is rotatably engaged within the threaded hole. A handle is coupled to a proximal end of the shaft, and a distal extension of the shaft comprises a driver. A distal force applicator comprises the driver centered between a first grip and a second grip. In some embodiments, the distal force applicator is configured to retain a surgical staple, such that the surgical staple may be changed to a distracted configuration suitable for implantation at a bone fixation or fusion site of a patient. In some embodiments, the distal force applicator is configured to bend a bone fusion plate so as to tailor the plate to specific anatomy of the patient's bone.

First claim

What is claimed is:

1. A surgical bending instrument for implanting a surgical staple at a bone fusion site of a patient, comprising:
a body supporting a first grip and a second grip that are configured to retain a crown of the surgical staple;
a driver configured to exert a distally-directed force onto a top of the crown between the first grip and the second grip; and
a proximal handle configured to move the driver longitudinally relative to the body;
wherein the first grip and the second grip have a separation distance comparable with a length of the crown; and
wherein the first grip and the second grip have an adjustable separation distance so as to facilitate retaining a variety of differently-sized surgical staples.

2. The surgical bending instrument of claim 1 , wherein the first grip and the second grip are disposed on the same side of the surgical staple and configured to support opposite ends underneath the crown.

3. The surgical bending instrument of claim 1 , wherein the first grip and the second grip are configured to forcibly retain the crown when the driver contacts the center of the crown.

4. The surgical bending instrument of claim 1 , wherein a shaft extending from the proximal handle to the driver is threadably engaged within the body, such that rotating the proximal handle moves the driver relative to the body.

5. The surgical bending instrument of claim 4 , wherein clockwise rotation of the proximal handle moves the driver distally and clasps the crown between the first grip, the second grip, and the driver, such that further clockwise rotation places the surgical staple into a distracted configuration suitable for implantation across the bone fusion site.

6. The surgical bending instrument of claim 5 , wherein counterclockwise rotation of the proximal handle moves the driver proximally, allowing the surgical staple to relax from the distracted configuration and compress the bone fusion site.

7. The surgical bending instrument of claim 1 , wherein the proximal handle comprises a lever coupled with a cam that is pivotally mounted within the body, such that proximal movement of the lever causes the cam to push the driver into forcible contact with the crown.

8. The surgical bending instrument of claim 7 , wherein moving the lever to a maximally proximal position places the surgical staple into a distracted configuration suitable for implantation across the bone fusion site.

9. The surgical bending instrument of claim 8 , wherein moving the lever distally allows the surgical staple to relax from the distracted configuration and compress the bone fusion site.

10. A surgical bending instrument for distracting a surgical staple for implantation at a bone fusion site of a patient, comprising:
a first grip and a second grip that are disposed on the same side of the surgical staple and configured to support opposite ends underneath a crown of the surgical staple;
a driver in mechanical communication with a proximal handle and configured to exert a distal force on top of the crown; and
a body supporting at least the first grip, the second grip, and the driver;
wherein the first grip and the second grip have a separation distance comparable with a length of the crown; and
wherein the first grip and the second grip have an adjustable separation distance so as to facilitate retaining a variety of differently-sized surgical staples.

11. The surgical bending instrument of claim 10 , wherein the proximal handle is configured to facilitate moving the driver distally to clasp the crown between the first grip, the second grip, and the driver, and thereby place the surgical staple into a distracted configuration suitable for implantation across the bone fusion site, and wherein the proximal handle is configured to move the driver proximally to allow the surgical staple to relax from the distracted configuration and compress the bone fusion site after implantation.

12. The surgical bending instrument of claim 10 , wherein the proximal handle is coupled with the driver by way of a shaft threadably retained within the body, whereby rotating the proximal handle moves the driver longitudinally with respect to the body.

13. The surgical bending instrument of claim 10 , wherein the proximal handle is coupled with the driver by way of a cam that is mounted pivotally within the body, whereby moving a lever coupled with the cam moves the driver longitudinally relative to the body.
