Description

Eye-connecting system for femtosecond laser ophthalmic equipment, its docking seat and the docking seat Eyelet

The invention relates to an eye-connecting system for femtosecond laser ophthalmic equipment, its docking seat and an eye-connecting ring installed on the docking seat.

In recent years, femtosecond laser (femtosecond laser) has been widely used in laser eye surgery due to its characteristics of ultrashort pulse, ultrahigh power, and ultrasmall spot. In detail, a femtosecond laser is a laser that operates in the form of ultrashort pulses (1 femtosecond is equivalent to 10 ^-15 seconds), and its main feature is that the duration of each laser pulse is only a few hundred femtoseconds , the instantaneous power can reach one trillion watts, and the energy of the laser pulse can be focused in a space smaller than the diameter of a hair. In addition, since the femtosecond laser has almost no heat conduction effect, it can be called a cold laser, which does not affect tissues other than the affected site.

The working principle of the femtosecond laser used in laser eye surgery is outlined below. First, the femtosecond laser generates extremely high energy density instantly in a very small space with extremely low energy, which ionizes the eye tissue and forms plasma. The electromagnetic field strength generated by the plasma is stronger than the force of the nucleus on its surrounding electrons It is also several times stronger, causing photolysis and blasting of eye tissue to produce tiny bubbles containing carbon dioxide and water, and thousands of laser pulses will produce thousands of tiny bubbles. Finally, these The interconnection of tiny air bubbles can achieve the effect of cutting eye tissue. Therefore, in the field of laser eye surgery, femtosecond laser can be used as an ultra-precision surgical scalpel, and has been successfully used in ophthalmic corneal refractive correction and other operations.

When using femtosecond laser in ophthalmic surgery, due to the accuracy of the femtosecond laser's focus position, it is necessary to fix the patient's eyeball with an eye socket device before the operation. The eye socket device usually includes an eye ring holder and an eye ring, and the eye ring fixes the patient's eyeball so that it cannot move freely relative to the eye ring holder. The eye socket device can be, for example, a one-piece design disclosed in U.S. Patent No. 8,623,001 applied by Zeiss, which includes an eye socket holder and an eye socket, and the eye socket is a disposable consumable, on which a PMMA curved plate is arranged as The reference surface of the cornea that touches the patient's eyeball. Before laser eye surgery, the eye ring is pre-fixed on the eye ring holder, and then the patient lying on the operating table is moved so that the center of the eyeball is aligned with the eye ring and fixed. Eyelets secure. In further words, in the eye contact device of Zeiss, in order to adjust the relative position between the eye contact device and the patient's eyeball to align the center, the operating table (patient) is moved in the X, Y, and Z directions to align the eyeball at the center. Then fix the patient's eyeball with the eye ring to complete the eye operation.

On the other hand, the eye fitting device can be, for example, the two-stage design disclosed in US Patent No. 8,858,581 filed by Wavelight, which includes an eye fitting ring and an eye pressing device, the eye fitting ring is a disposable consumable, and the eye pressing device A PMMA plate is set as the reference surface of the cornea in contact with the patient's eyeball. Before laser eye surgery, the eye ring is first positioned on the patient's eyeball, and then the operating table is moved along the X and Y directions to make the patient's eyeball Following the movement, when the eye ring (the patient's eyeball) is moved directly below the eye-indentation device, move the eye-indentation device along the Z direction to complete the eye-in-the-eye step.

The common shortcoming of the above two types of eye-connecting devices is that before performing laser eye surgery, it is necessary to move the operating table to move the patient's eyeball so that it is aligned with the eye-connecting ring. Moving the patient (operating table) under certain circumstances will increase the patient's sense of nervousness, for example, the patient's eyeballs will turn unconsciously due to tension, etc., making the operation more complicated and prolonging the time required for the entire operation.

In addition, compared with the one-stage design of the Zeiss eye socket device, the eye socket step is completed after the eyeball is fixed by the eye socket, although the two-stage design of the WaveLight eye socket device is easier to position the eye socket (because the positioning of the eye socket The fully manual method is more flexible), but after the eyeball is fixed to the patient's eye by the eye ring, it is necessary to control the combination of the eye pressure device and the eye ring, and the accuracy of this part is difficult to control.

Accordingly, there is a need for an eye socket device that reduces the patient's sense of jitters while controlling the precision of the eye socket.

The present invention provides an eye-receiving system for femtosecond laser ophthalmic equipment, which enables an eye-receiving ring to be docked with the patient's eyeball with higher precision, and can also replace the position of the patient by moving the eye-receiving ring. The operating table moves to achieve alignment to relieve patient jitters.
