Integral system of laser cornea operations

Abstract

The invention discloses an integral system of laser cornea operations. The system comprises a near-infrared pulse laser, a laser transmission device and a laser positioning device and is also provided with a laser wavelength conversion device, wherein the output end of the laser wavelength conversion device coaxially outputs basic near-infrared pulse laser and quintupled frequency ultraviolet pulse laser is obtained through frequency mixing; and the laser transmission device divides an optical path into a near-infrared branch optical path and a quintupled frequency ultraviolet branch optical path which are transmitted and controlled separately and are superposed to form an output optical path after passing through a dichroic mirror so as to be transmitted to a target position. The integral system separately controls two types of laser by properly using frequency doubling and mixing technology and using reasonable and artful light splitting and adjusting means; and therefore, the integral system perfectly realizes completing near-infrared and ultraviolet laser therapeutic means through making use of the same set of laser therapeutic equipment and realizes free conversion between both types of the laser, thereby simplifying operation procedures, greatly reducing operation time and possible hidden danger and bringing great convenience to both doctors and patients.

Description

technical field [0001] The invention relates to a laser device, in particular to a medical laser operation device. Background technique [0002] Laser corneal surgery has been widely used to correct the refractive error of the human eye, remove corneal scars and corneal transplantation, especially laser corneal refractive surgery has become a preferred method for myopia correction, and its safety and effectiveness have been obtained. Scientific validation and broad acceptance. The method generally adopted at present is to first cut a corneal flap with a mechanical knife called a corneal lamellar knife. After the corneal flap is lifted, the ArF excimer laser cuts the corneal tissue. However, because the penetration of ultraviolet laser on corneal tissue is very small, it is only suitable for surface cutting, and the model is large, the energy stability is poor, and it is easy to be affected by the image of ambient temperature and humidity. In addition, due to its design and...

Problems solved by technology

"Its shortcomings are: 1. The system is complex; 2. It does not involve the optional or successive use of near-infrared laser and ultraviolet laser to cut corneal tissue.

[0006] In corneal surgery, it is often necessary to use basic near-infrared pulsed laser and quintuple-frequency ultraviolet pulsed laser to operate on the treatment surface. However, in the prior
