Description

Technical Field

[0001] The present invention relates to the technical field of ophthalmic surgery, and particularly relates to an ophthalmic cutting device and a cutting method. Background Art

[0002] The full name of ophthalmology is "specialty of eye diseases", which is a discipline that studies diseases occurring in the visual system, including the eyeball and its associated tissues. Ophthalmology generally studies various ophthalmic diseases such as vitreous and retinal diseases, optometry, glaucoma and optic nerve diseases, and cataracts.

[0003] Most ophthalmic surgeries use laser cutting, which has higher precision than manual operation and is not prone to operation errors. When the existing laser cutters are used, manual adjustment is required, with too low adjustment precision, and the operation is cumbersome, time-consuming and laborious. During ophthalmic surgery, the patient's head may shake. Once shaking occurs, the surgery will fail. Therefore, we propose an ophthalmic cutting device and a cutting method to solve the above-mentioned problems. Summary of the Invention

[0016] A cutting method for an ophthalmic cutting device, comprising the following steps:

[0017] S1. The patient lies on the bed board, places the head on the support board. The support board drives the support board to move vertically downward under pressure. The support board drives the cross bar to move vertically downward and compress the first spring. At this time, the support board enters the first installation groove, and the cross bar enters the second installation groove. The cross bar no longer blocks the sliding block;

[0018] S2. The sliding block moves horizontally under the elastic force of the compression spring. The sliding block drives the rectangular plate to move horizontally. The rectangular plate drives the mounting plate and the fixed block to move horizontally. The patient's face abuts against the second rubber pad and pushes the mounting plate into the interior of the rectangular plate. The mounting plate drives the round rod to move horizontally and compress the second spring. The round rod drives the fixed block to move horizontally;

[0019] S3. At this time, the cross plate is no longer engaged with the second card slot. The cross plate moves vertically downward under the pulling force of the tension spring. The cross plate drives the block to move vertically downward and engage with the corresponding first card slot. At this time, the two rectangular plates cannot move, preventing the patient's head from shaking during the operation and being able to adapt to a variety of patients with a wide range of applications;

[0020] S4. Start the first electric push rod. The piston rod of the first electric push rod drives the first sliding plate to move vertically downward to adjust the height of the laser cutter. Start the second electric push rod. The piston rod of the second electric push rod drives the second sliding plate to move horizontally to adjust the horizontal position of the laser cutter. Finally, by starting the servo motor, the output shaft of the servo motor drives the lead screw to rotate. The lead screw drives the threaded block to move horizontally and can drive the laser cutter to move horizontally to complete the cutting process.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In the present invention, the patient lies on the bed board, places the head on the support board. The support board drives the support board to move vertically downward under pressure.

The rectangular plate drives the mounting plate and the fixed block to move horizontally. The patient's face abuts against the second rubber pad and pushes the mounting plate into the interior of the rectangular plate. The mounting plate drives the round rod to move horizontally and compress the second spring. The round rod drives the fixed block to move horizontally;

[0024] 3. In the present invention, at this time, the horizontal plate is no longer engaged with the second card slot. Under the pulling force of the tension spring, the horizontal plate moves vertically downward. The horizontal plate drives the clamping block to move vertically downward and engage with the corresponding first card slot. At this time, the two rectangular plates cannot move, preventing the patient's head from shaking during the operation. At the same time, it can adapt to a variety of patients, with a wide range of applications.

[0025] 4. In the present invention, start the first electric push rod. The piston rod of the first electric push rod drives the first sliding plate to move vertically downward to adjust the height of the laser cutter. Start the second electric push rod. The piston rod of the second electric push rod drives the second sliding plate to move horizontally to adjust the horizontal position of the laser cutter. Finally, start the servo motor.
