FREE FLOATING PATIENT INTERFACE FOR LASER SURGERY SYSTEM

摘要

Systems and methods here may be used to support a laser eye surgery device, including a base assembly mounted to an optical scanning assembly via, a horizontal x axis bearing, a horizontal y axis bearing, and a vertical z axis bearing, mounted on the base assembly, configured to limit movement of the optical scanning assembly in an x axis, y axis and z axis respectively, relative to the base assembly, a vertical z axis spring, configured to counteract the forces of gravity on the optical scanning assembly in the z axis, and, mirrors mounted on the base assembly and positioned to reflect an energy beam into the optical scanning assembly no matter where the optical scanning assembly is located on the x axis bearing, the y axis bearing and the z axis bearing.

1. A system to support a laser eye surgery device, comprising:
a beam source configured to generate an electromagnetic radiation beam to a variable optical path; a scanner configured to scan a focal point in different locations within the eye; a sensor to receive a portion of the electromagnetic radiation beam reflected from the focal point location back along the variable optical path, and generate an intensity signal indicative of the intensity of a portion of the electromagnetic radiation beam reflected from the focal point location and propagated to the sensor; a base assembly mounted to a movable optical scanning assembly via,
a horizontal x axis bearing configured to limit movement of the optical scanning assembly in an x axis;a horizontal y axis bearing, mounted on the base assembly, configured to limit movement of the optical scanning assembly in a y axis;a vertical z axis bearing, mounted on the base assembly, configured to limit movement of the optical scanning assembly in a z axis;a vertical z axis spring, configured to counteract the forces of gravity on the optical scanning assembly in the z axis; and, at least three mirrors mounted on the base assembly and positioned to reflect the beams into the optical scanning assembly along the variable optical path no matter where the optical scanning assembly is located on the x axis bearing, the y axis bearing and the z axis bearing.
