Surgical laser guide and method of use
View Patent ↗Methods and apparatus for aligning two or more longitudinally space parts of a body, such as leg bones, prior to and/or during a surgical procedure using a laser light guide assembly are described. The apparatus may have a saddle for attachment to a specific body part, and comprises a first horizontally rotatable structural member pivotably secured to the saddle or other support means, and a second rotatable structural member aligned vertically and perpendicular to the first structural member. A laser light guide which includes a laser is attached to the second structural member, the laser capable of generating a laser light beam of sufficient strength and intensity to allow for alignment of the body parts prior to and during a surgical procedure.
1. A method for fixation of a first bone fragment on a first side of a bone fracture and a second bone fragment on a second side of the bone fracture, comprising:
contacting a concave interior surface of a laser guide assembly including a laser to a first surface of a mammal's body on the first side of the fracture;
positioning the laser guide assembly relative to the first bone fragment;
projecting a beam of the laser onto a second surface of the mammal's body on the second side of the fracture to produce a reference point;
aligning the first bone fragment and the second bone fragment with regard to the reference point; and
securing the first bone fragment to the second bone fragment such that the first bone fragment and the second bone fragment are in a position that is anatomically correct.
2. The method of claim 1 , further comprising horizontally and/or vertically adjusting the laser within the laser guide assembly.
3. The method of claim 2 , wherein horizontally adjusting the laser within the laser guide assembly comprises horizontally rotating a horizontal member within the laser guide assembly.
4. The method of claim 2 , wherein vertically adjusting the laser within the laser guide assembly comprises vertically rotating the laser within the laser guide assembly.
5. The method of claim 2 , wherein vertically adjusting the laser within the laser guide assembly comprises vertically sliding the laser within the laser guide assembly.
6. The method of claim 1 , wherein the mammal is a human.
7. The method of claim 1 , wherein positioning the laser guide assembly relative to the first bone fragment comprises detecting positioning of radio-opaque objects associated with the laser guide assembly relative to the first bone fragment.
8. The method of claim 1 , wherein securing the first bone fragment to the second bone fragment comprises an intramedullary nailing.
9. The method of claim 1 , wherein the bone fracture is in a leg bone.
