Devices, systems, and methods for inserting and removing surgical wires
A surgical wire is part of a system that includes a retractor blade defining one or more paths for the surgical wire to follow. The paths can be one or more openings, cannulations, paths, tubes, other structures, or combinations thereof. The surgical wire can be routed through the front, back, and/or middle of the retractor blade and into a vertebral body. The surgical wire can be routed through a shim in communication with the retractor blade and into a vertebral body Systems and methods are used to insert surgical wires into bone. Systems and methods are used for removing surgical wires from bone. Systems include those for gripping and pulling or pushing surgical wires. Systems include those that interact with a retractor (e.g., an arm, body, or blade thereof) to facilitate removal of the surgical wire.
1 . A retractor blade for creating an operating corridor to an operative site comprising:
a body having a proximal end and a distal end, wherein the proximal end of the body is further away from the operative site than the distal end of the body; and
a surgical wire path beginning proximate the proximal end of the body and ending proximate the distal end of the body,
wherein the surgical wire path comprises a first opening in communication with the surgical wire path, the first opening is proximate the proximal end of the body and a second opening in communication with the surgical wire path, the second opening is proximate the distal end of the body,
wherein the surgical wire path comprises a first surgical wire path and a second surgical wire path,
wherein the first surgical wire path and the second surgical wire path converge and meet proximate the distal end of the body, and
wherein the first surgical path and the second surgical path both exit the body at a same distal opening at the distal end of the body,
wherein the first surgical wire path and the second surgical wire path have a first portion in which the first surgical wire path and the second surgical wire path are parallel and a second portion in which the first surgical wire path and the second surgical wire path converge toward one another.
2 . The retractor blade of claim 1 , wherein the surgical wire path has a first section in which the surgical wire path is parallel to a midline of the body, a second section in which the surgical wire path is angled toward the midline of the body, a third section in which the surgical wire path is angled toward the midline of the body, and a fourth section in which the surgical wire path is angled toward the midline of the body.
3 . The retractor blade of claim 2 , wherein the surgical wire path is straight in the first section and the second section and the surgical wire path is curved in the third section.
4 . The retractor blade of claim 1 , wherein the surgical wire path has a first portion completely enclosed and a second portion formed from an open channel.
5 . The retractor blade of claim 1 , wherein the body defines the surgical wire path.
6 . The retractor blade of claim 1 , further comprising:
a tube defining the surgical wire path,
wherein the tube extends along the body from a location proximate the proximal end of the body to a location proximate the distal end of the body.
7 . The retractor blade of claim 6 , wherein the tube is sunk into a face of the body.
8 . The retractor blade of claim 6 , wherein the tube comprises a first tube and a second tube spaced distally from the first tube.
9 . The retractor blade of claim 8 , wherein the first tube is straight and the second tube is curved.
10 . A system comprising:
a retractor comprising a retractor blade, wherein the retractor blade has a proximal end and a distal end and the proximal end of the retractor blade is configured to couple to the retractor;
a surgical wire path extending along the retractor blade, the surgical wire path having a proximal opening proximate the proximal end of the retractor blade and a distal opening proximate the distal end of the retractor blade; and
a surgical wire configured to extend along the surgical wire path from the proximal opening to the distal opening,
wherein the surgical wire path comprises a first surgical wire path and a second surgical wire path,
wherein the first surgical wire path and the second surgical wire path converge and meet proximate the distal end of the body, and
wherein the first surgical path and the second surgical path both exit the body at a same distal opening at the distal end of the body,
wherein the surgical wire path is defined by:
a full enclosure in a first section; and
an open channel in a second section.
11 . The system of claim 10 , wherein the surgical wire path is defined by a tube extending along the retractor blade, the surgical wire path is configured to receive the surgical wire.
12 . The system of claim 10 , wherein the surgical wire path includes:
a straight section angled toward a midline of the retractor blade; and
a curved section angled toward the midline of the retractor blade.
13 . The retractor blade of claim 1 , wherein the first surgical path and the second surgical path are asymmetrical.
