Laser assisted surgical resection alignment guide
View Patent ↗The present invention relates to a laser assisted surgical resection alignment guide for performing joint resection surgery. The present invention includes a base plate containing a switch which activates orthogonal laser assemblies when the laser assisted surgical resection alignment guide is inserted into a surgical block. The orthogonal laser assemblies each project beams which are each refracted by lenses to project two laser lines onto a human who has been prepared for surgery.
1. A laser guide comprising: a base plate, an end plate, a horizontal laser assembly, a vertical laser assembly, a switch, and a battery; wherein said horizontal laser assembly and said vertical laser assembly both comprise a laser emitting device and a lens, said lens being affixed to a light emitting end of said laser emitting device;
wherein said horizontal laser assembly is affixed to said base plate, parallel to said base plate, and said vertical laser assembly is affixed to said end plate, orthogonal to said end plate;
wherein said switch and said battery are affixed to said base plate, and said switch, said horizontal laser assembly and said vertical laser assembly are electrically connected to said battery; and
wherein said end plate is rotationally connected to said base plate.
2. The laser guide of claim 1 , wherein said base plate further comprises an insertion plate and said insertion plate further comprises a raised flexible tab; wherein said insertion plate is on an opposite side of said base plate from said end plate; and wherein said insertion plate may be inserted into a surgical block and held in place by said raised flexible tab.
3. The laser guide of claim 2 , wherein said base plate and said insertion plate are coplanar, said base plate extends beyond a width of said insertion plate, and said end plate is offset horizontally from said insertion plate.
4. The laser guide of claim 3 , wherein said lens of said horizontal laser assembly refracts laser light into a horizontal plane and said lens of said vertical laser assembly refracts laser light into a vertical plane.
5. The laser guide of claim 4 , wherein said surgical block is configured to be mounted on a human bone for performing a surgery, when said laser guide is inserted into said surgical block, and said surgical block is mounted on said human bone for performing said bone surgery, and said laser guide is switched on, then said horizontal laser assembly refracts laser light onto said human bone creating a horizontal projection, and said horizontal projection is a proposed location for performing a cut of said bone surgery in said horizontal plane.
6. The laser guide of claim 5 , wherein when said laser guide is inserted into said surgical block, said vertical laser assembly refracts laser light onto bone below said human bone creating a vertical projection, and said vertical projection indicates alignment of said cut of said bone surgery.
7. The laser guide of claim 6 , wherein said end plate and said base plate are rotationally connected by a rotational locking mechanism, allowing said end plate and said base plate to be fixed in a coplanar position when locked and also allowing said base plate to rotate at least 180 degrees to allow projection of laser light in an opposite direction and allowing said laser guide to be used with one or more types of human bones.
8. The laser guide of claim 7 , wherein said rotational locking mechanism allows said base plate to be rotationally locked in place at 0 degrees, 45 degrees, 135 degrees, 180 degrees, 225 degrees, and 315 degrees relative to said base plate.
9. The laser guide of claim 7 , wherein said rotational locking mechanism comprises a first ridged connector plate having first ridges and a second ridged connector plate having second ridges, wherein compressive force holds said first ridges against said second ridges and said first ridged connector plate is rotatable relative to said second ridged connector plate upon application of rotational force sufficient to overcome said compressive force.
10. The laser guide of claim 9 , wherein said laser guide further comprises a second horizontal laser assembly comprising a laser emitting device and a lens, said lens being affixed to a light emitting end of said laser emitting device; wherein said second horizontal laser assembly is affixed to said base plate parallel to said base plate; and wherein said second horizontal laser assembly refracts laser light into said horizontal plane.
11. The laser guide of claim 10 wherein said vertical laser assembly is rotatable relative to said end plate in an axis orthogonal to said end plate.
