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.
Claims13
An instrument for bending a surgical implant about a bending axis, comprising:
- a handle defining a receiving area for receiving the surgical implant;
- a lever pivotably connected to the handle about a pivot axis that is orthogonal to the bending axis;
- and
- a movable linkage connected to the lever for movement therewith, the moveable linkage being configured to bend the surgical implant about the bending axis upon pivoting the lever about the pivot axis,
- the movable linkage comprising a carriage that is translatable on the handle upon pivoting the lever about the pivot axis,
- the carriage including a friction member that is configured to engage with a friction surface on the handle as the carriage is translated with respect to the handle, and
- the friction member comprising a flexible arm having a tooth, and the friction surface comprising a toothed surface defined on the handle.

An instrument for bending a surgical implant about a bending axis, comprising:
- a handle defining a receiving area for receiving the surgical implant;
- a lever pivotably connected to the handle about a pivot axis that is orthogonal to the bending axis;
- a movable linkage connected to the lever for movement therewith, the moveable linkage being configured to bend the surgical implant about the bending axis upon pivoting the lever about the pivot axis;
- the movable linkage comprising a carriage that is translatable on the handle upon pivoting the lever about the pivot axis;
- a central roller mounted to the carriage;
- side rollers mounted to the handle adjacent the central roller;
- a space formed between the central roller and the side rollers in which the surgical implant is configured to be positioned;
- and
- a template rod holder mounted to the central roller,
- wherein movement of the central roller toward the side rollers causes the surgical implant to bend about the bending axis.

An instrument for bending a surgical implant, comprising:
- a handle defining a receiving area for receiving the surgical implant;
- a lever pivotably connected to the handle about a pivot axis;
- and
- a movable linkage connected to the lever, the moveable linkage being configured to translate in a first direction to bend the surgical implant about a bending axis upon pivoting the lever about the pivot axis;
- a friction member extending from the moveable linkage for limiting translation of the moveable linkage in a second direction that is opposite the first direction upon releasing the lever;
- the movable linkage comprising a carriage that is translatable on the handle upon pivoting the lever about the pivot axis;
- the carriage including the friction member that is configured to engage with a friction surface on the handle as the carriage is translated with respect to the handle;
- and
- the friction member comprising a flexible arm having a tooth, and the friction surface comprising a toothed surface defined on the handle.
6 more elements
An instrument for bending a surgical rod, comprising:
- a handle defining a receiving area for receiving the surgical rod;
- a lever pivotably connected to the handle;
- and
- a template rod holder mounted to one of the handle and the lever at a location adjacent the receiving area, the template rod holder being configured for holding a template rod having a bent shape that can be used as a template for bending the surgical rod about a bending axis;
- a movable linkage connected to the lever, the moveable linkage being configured to bend the surgical rod upon pivoting the lever;
- the movable linkage comprising a carriage that is translatable on the handle upon pivoting the lever;
- a central roller mounted to the carriage;
- side rollers mounted to the handle adjacent the central roller;
- and
- a space formed between the central roller and the side rollers in which the surgical rod is configured to be positioned,
- wherein movement of the central roller toward the side rollers causes the surgical rod to bend about the bending axis, and
- wherein the template rod holder is mounted to the central roller.
