Embodiment Construction

[0014] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and processes are provided, but the protection scope of the present invention is not limited to the following implementations example.

[0015] As shown in FIG. 1 , this embodiment includes five modules, namely: a scanning laser source, an adaptive positioning system, a safety parameter testing system, a treatment effectiveness testing system, and a controller. Along the direction of the laser beam, the scanning laser source is directly aimed at the human eye; the input ends of the adaptive positioning system, the safety parameter test system and the treatment effect test system are all aimed at the human eye, and the output ends of the three are connected with the input end of the controller connected. The output ...

Abstract

A scanning laser operation system for the thermo-shaping operation of cornea on living body is composed of a scanning laser source, an adaptive locating system, a safte parameter testing system, a therapeutic effect testing system, and a controller.

Description

technical field [0001] The invention relates to a system in the technical field of biomedical engineering, in particular to a living body operation system for scanning laser keratoplasty. Background technique [0002] As people's understanding of hyperopia continues to deepen and the number of hyperopic people continues to grow, the treatment of hyperopia is becoming more and more a hot spot in the field of ophthalmology. There are several methods for the treatment of hyperopia, including excimer laser refractive keratotomy, excimer laser in situ keratomileusis, laser thermoplasty, clear lens extraction combined with intraocular lens implantation, automatic lamellar Keratoplasty, Keratotomy, Lasso and more. Among them, laser keratoplasty is the use of laser light to irradiate the cornea, so that the corneal collagen fibers are heated and contracted, and the refractive power of the cornea is changed to treat ametropia. Since laser thermoplasty is a non-invasive treatment us...
