Abstract
A system, medical devices, and methods for use in surgical procedures, such as spinal surgeries. The system, medical devices, and methods are designed to provide a surgeon the ability to add a screw connector, or screw head such as a tulip, to pre-existing implanted bone, such as pedicle, facet, lateral mass, etc., screw system without having to remove the previously implanted screws and/or rods already existing in a patient.
Claims20
An apparatus configured to engage an anchoring point of an implanted bone screw system, the apparatus comprising:
- a first end separated from a second end by an elongated body;
- a set of apertures at the first end configured to engage structural elements of another retractor system;
- and
- a securing tip at the second end, wherein the securing tip selectively engages the anchoring point of the implanted bone screw system based on an amount of travel of a locking actuator along a length of the elongated body towards the second end.
A system comprising:
- an implanted bone screw system including at least one anchor point, the at least one anchor point including a connecting rod and a tulip head;
- a tower assembly coupled to the anchor point of the implanted bone screw system, the tower assembly comprising:
- a first end separated from a second end by an elongated body;
- a set of apertures at the first end configured to engage structural elements of another retractor system;
- and
- a securing tip at the second end, wherein the securing tip selectively engages the anchoring point of the implanted bone screw system based on an amount of travel of a locking actuator along a length of the elongated body towards the second end.
A method of securing a tower assembly to an anchor point of an implanted bone screw system, the method comprising:
- aligning a securing tip of the tower assembly with the anchor point of the implanted bone screw system, wherein the tower assembly includes:
- a first end separated from a second end by an elongated body, wherein the securing tip is located at the second end, and
- a set of apertures at the first end configured to engage structural elements of another retractor system;
- actuating a locking actuator to cause the locking actuator to travel along a length of the elongated body towards the second end, wherein the securing tip selectively engages the anchor point of the implanted bone screw system based on an amount of travel of the locking actuator.
