Embodiment 1

[0036] combine figure 1, a treatment device for age-related macular degeneration, comprising an industrial computer 1 and a control interface circuit 2 connected to the industrial computer 1, the control interface circuit 2 uses a single-chip microcomputer as a processor and communicates with the industrial computer 1 through an RS232 bus. The control interface circuit 2 is connected to a DC stabilized power supply 4, the DC stabilized power supply 4 also provides electric energy for the laser driver 5, the DC stabilized power supply 4 is also connected to a display screen 3, and the single-chip microcomputer uses ADμC848 as the core processor , communicate with the touch screen through the asynchronous serial interface, receive the control information of the industrial computer and send the display command, coordinate the automatic power control circuit and the automatic temperature control circuit, and detect the working current, working voltage and control voltage of the las...

Embodiment 2

[0041] combine image 3 and Figure 4 , the laser driver 5 includes a fixed seat 51 and a resonant cavity 52 located in the fixed seat 51, the fixed seat 51 is provided with three support rods 53 arranged along the length direction of the fixed seat 51, two of the fixed seat 51 Two resonant cavity mirrors 54 are respectively arranged at the ends, and the resonant cavity 52 is arranged between the two resonant cavity mirrors 54. The fixed seat 51 is a right-angled base formed by two fixed plates perpendicular to each other. The three support rods They are respectively fixed on the right-angle side of the fixing seat and the other side of the fixing plate relative to the right-angle side, so as to maintain the mechanical stability of the resonant cavity 52 and maintain a strong laser output.

[0042] The resonant cavity 52 includes a mirror 521, a Nd:YAG crystal rod 522, an isolation mirror 523, a KTP frequency doubling crystal 524, an output mirror 525, and a fiber coupling mi...

Embodiment 3

[0045] The laser driver also includes a pumping element, the pumping element includes a Nd:YAG crystal rod and a cooling tube wrapped by the Nd:YAG crystal rod, the outside of the cooling tube is provided with a reflector, the Through holes are evenly spaced on the reflector, and the semiconductor laser of the laser driver is injected into the Nd:YAG crystal rod through the through holes on the reflector through the collimating mirror, and the three semiconductor lasers are evenly arranged along the circumference of the Nd:YAG crystal rod It is pumped to make the light intensity distribution on the surface of the working substance more even, and more pumping energy is concentrated in the central part to obtain a higher power laser output.

[0046] Assuming that the round-trip loss of the fundamental mode Gaussian beam in the resonator is δ, and the crystal length is L, then δ=L / cτ c , where τ c is the average lifetime of photons in the resonator, and c is the refractive index...

Abstract

The invention relates to a treatment device for age-related macular degeneration. The treatment device comprises an industrial personal computer and a control interface circuit connected with the industrial personal computer, and is characterized in that the control interface circuit is connected with an optical fiber coupler through a laser driver, the optical fiber coupler combines lasers with different wavelengths emitted by the laser driver and transmits the lasers to the eyes of a patient through the same optical fiber, the lasers emitted by the eyes of the patient and the laser driver are reflected to the position below a light source of a slit-lamp microscope through a lens, and the lasers and the light source of the slit-lamp microscope are in the same light path to the fundus of the eyes of the patient. The treatment device provided by the invention can generate lasers with multiple wavelengths and output the lasers independently or simultaneously, and can treat lesions of multiple parts or compound lesions of the same part at the same time, so that the range of the lasers applied to treatment of fundus diseases is expanded, the cure rate of an operation is improved, meanwhile, the operation time can be saved, and the pain of the patient is relieved.

Description

technical field [0001] The invention belongs to the technical field of eye disease treatment, and in particular relates to a treatment device for age-related macular degeneration. Background technique [0002] Although the eyes are small, their structures are complex. Fundus disease is one of the frequently occurring diseases of the eyes, and its causes are also very complicated. Usually, it is easy to cause vision loss in the early stage of the disease. If it is not treated in time, the blindness rate is extremely high. Fundus disease changes are caused by lesions in the membrane layer of the eyeball wall. The wall of the eyeball has three layers of membranes. The first layer is the retina, which directly receives light behind the vitreous body; the brown choroid, which is rich in blood vessels; and the last is the white sclera, which is the outer layer. If retinal or choroidal lesions occur, it will cause fundus lesions and lead to paralysis of eye function. The most comm...
