Embodiment Construction

[0016] The self-controlled laser surgery device for glaucoma filtration is mainly composed of CO2 main laser (1), semiconductor guiding light laser (2), area array CCD camera device (3), image acquisition card (4), interface circuit between laser and microcomputer (5) , several parts such as PC machine (6) and software system (7).

[0017] In the embodiment shown in Fig. 1, utilize high-speed I / O interface circuit (5), PC (6) and laser (1) are connected together, use D / A conversion to complete the function of setting parameters and controlling laser switch, A The / D conversion can monitor the state of the foot switch in real time to record the total number of actual pulses or the total action time of the laser (1).

[0018] The image acquisition card (4) directly takes the video signal of the CCD camera (3) as input without signal preprocessing; the analog signal is directly communicated with the microcomputer via the PCI bus after A / D conversion.

[0019] The software system...

Abstract

The invention is glaucoma filter automatic controlled laser operator for curing glaucoma. The system is made up of software and hardware; the hardware is made up of laser, guiding light laser, image picking device, mechanism frame and computer, the guiding laser is assembled in the box of primary laser, the laser knife of the primary laser is connected with the image picking device through mechanical frame, and it is connected to the computer through interface card or interface circuit; the work of each hardware is connected by software. It uses image picking device to acquire the image information of the focus part, and monitors the operation process in real-time; the system combines the active control and the feedback control, monitors the operation process in real-time and shuts off the laser automatically after the operation has been completed, it can acquires the best working parameter, and reduces the damage to the lowest effectively.

Description

technical field [0001] The invention relates to a medical device, especially an ophthalmic laser surgical device, which is a self-controlled glaucoma laser surgical device with multiple control modes, real-time monitoring of the surgical process, and adjustable parameters for glaucoma filtering surgery. Background technique [0002] Surgery is the main means of treating glaucoma, and filtering surgery has always been a research hotspot in glaucoma therapy. At present, traditional filtering surgery mainly includes trabeculectomy and scleral bite. However, there are many complications after traditional filtering surgery, such as shallow anterior chamber and no anterior chamber, ciliary prolapse, malignant glaucoma, hemorrhage, and non-formation of filtering blebs in the early stage; Scarring, cystoid degeneration, bleb rupture, cataract, and infection. The remarkable advantages of laser anti-glaucoma filtration surgery are simplicity, safety, easy control of operation volume...
