Hand-held laser scanner
First Claim
1. A surgical system for connection to a laser that generates a pulsed laser beam, wherein the surgical system scans the laser beam onto a target tissue, the surgical system comprising:
- a scanning mirror means for reflecting a pulsed laser beam;
a lens onto which the scanning mirror means reflects the pulsed laser beam and through which the pulsed laser beam is refracted onto the target tissue; and
a controller that operates the scanning mirror means to scan the pulses in the laser beam to form a selected pattern of spots on the target tissue, the controller being responsive to a control panel that includes;
a pattern selector for selecting the selected pattern from a plurality of predetermined patterns, andan overlap selector for selecting the relative spacing between the spots in the selected pattern.

Abstract
A surgical laser scanner having optics that scans a pulsed laser beam onto a target tissue is disclosed. The laser scanner has a lens and a scanning mirror or mirrors located upstream of the lens at a distance substantially equal to the focal length of the lens. The laser beam hits the scanning mirror and is reflected onto the lens in a pattern defined by sequential positions of the scanning mirror. The laser beam is projected onto the target tissue by the lens in a direction parallel to the optical axis of the lens. The projected pattern has a constant size regardless of the distance between the laser scanner and the target tissue.

9. A surgical handpiece for connection to a laser that generates a laser beam, wherein the handpiece scans the laser beam onto a target tissue, the handpiece comprising:
-
a scanning mirror means for reflecting the laser beam; and a lens onto which the scanning mirror reflects the laser beam and through which the laser beam is refracted onto the target tissue, wherein the lens has a focal length and the scanning mirror is located at a distance from the lens that is substantially equal to the focal length so that any variation in the size of a pattern projected onto the target tissue is minimized as the spacing between the lens and the target tissue is varied.
