Problems solved by technology

Traditional filtering surgery mainly includes trabeculectomy and scleral bite, but there are many complications after traditional filtering surgery, such as early postoperative shallow anterior chamber and no anterior chamber, ciliary prolapse, malignant Glaucoma, hemorrhage, and non-formation of filter blebs, etc.; late stage filter orifice blockage, scar formation, cystoid degeneration, filter bleb rupture, cataract, infection, etc.
The existing laser microsurgery system mainly observes the changes of the biological tissue irradiated by the laser in real time through the microscopic system, and manually controls the amount of laser irradiation during the operation according to the needs of the operation. Therefore, these treatment equipment and treatment methods must observe the operation situation while manually controlling the amount of laser irradiation during the entire operation process, which is cumbersome. Most surgeons rely on their surgical experience to perform laser surgery. It is difficult to control the operation well, and there are still many problems to be solved urgently

Abstract

The invention provides automatic control laser operation equipment and a treatment method thereof. The equipment consists of a master controller, a monitor, a CCD camera, a laser, a light source, a master bracket, a cantilever, a hanging operation treatment head, a microscope observing system and a microscope operation adapter. The master controller recognizes and processes the image and spectrumof the focus tissue and the normal tissue collected by the CCD camera, and then gives out orders to control the work of the laser accordingly, thus avoiding operation mistakes caused by normal tissuedamage due to incorrect manipulation in laser operation; the master controller gives out orders to control the start and close of the laser and to correct the amount of laser output; a optical lens group forms a light path; and the microscope observing system, microscope inspection glass, the CCD camera and the microscope operation adapter are integrated into a whole by the optical lens group. Theinvention has simple structure, reasonable design and simple and easy operation; the normal tissue is not damaged while the focus tissue is removed in the operation; the invention is characterized inthat the equipment has a plurality of control modes; the parameters are adjustable; the application is wide. The invention can precisely control the operation extent and improve the treatment effect.

Description

Technical field [0001] The invention relates to a laser surgery medical instrument, in particular to a self-control laser surgery equipment. Background technique [0002] The use of laser microsurgery for surgery has been widely used, not only in surgery, internal medicine, ENT, and ophthalmology. In the treatment of glaucoma, laser microsurgery is the main method of treatment. Traditional filtering surgery mainly includes trabeculectomy and scleral bite surgery, but traditional filtering surgery has many postoperative complications, such as early postoperative shallow anterior chamber and no anterior chamber, ciliary artery prolapse, malignancy Glaucoma, hemorrhage, and failure to form filtering vesicles, etc.; late filtering mouth blockage, paralysis scar formation, cystic change, rupture of filtering vesicles, cataracts and infections. The existing laser microsurgery system mainly observes the changes of the biological tissues irradiated by the laser in real time through the ...
