Abstract
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.
Claims10
A method of verifying a position of a surgical cut, comprising the steps of:
- (1) inserting a laser guide into a surgical block mounted on a knee of a human for performing a knee surgery;
- (2) enabling said laser guide to project horizontal laser light and vertical laser light onto said human;
- (3) using said horizontal laser light to verify a position of said surgical cut;
- and
- (4) using said vertical laser light to verify alignment of said surgical cut;
- wherein said laser guide comprises 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.
