In this embodiment, the inner side of the abutting seat 403 is an arc-shaped curved surface and is made of soft rubber.

In this embodiment, cornea dropping mechanism 4 is including installation section of thick bamboo 501, push pump 502, light source 503 and dropping liquid pendulum head 504, installation section of thick bamboo 501 fixed mounting is on push pedal two 408, push pump 502 demountable installation is in installation section of thick bamboo 501, light source 503 fixed mounting is in lower extreme one side of installation section of thick bamboo 501, dropping liquid pendulum head 504 rotates through pivot 505 and sets up in the lower extreme opposite side of installation section of thick bamboo 501, pivot 505 runs through installation section of thick bamboo 501 and links to each other with the short rod section of push rod 410.

It should be noted that the driving motor 401 is a servo motor, the model of the bolus pump 502 is G12ZYB, and both are suitable for a sterile environment.

In this embodiment, the setting of slide plate 2 at the adjustable of operating table 1's upper surface is applicable to multiple size patient, and controls different eye position operations and all be applicable.

In this embodiment, the installation cylinder 501 is a hollow structure, and the physiological saline is filled between the inner wall of the installation cylinder 501 and the injection pump 502, and the end of the installation cylinder 501 is matched with the liquid inlet at the upper end of the dropping swing head 504.

The working process and principle are as follows: in the using process of the invention, firstly, a patient lies on the back on the sliding plate 2, the sliding plate 2 is adjusted to the end position by pushing the sliding plate 2 to slide, the positioning is completed on the operating table 1 according to the body type and the diseased eye position of the patient, then the driving motor 401 is started to lead the output end of the driving motor to drive the swing rod 405 to rotate, the end part of the swing rod 405 slides in the strip-shaped opening 406 and drives the swing piece 402 to rotate around the hinge point with the second push plate 408 for a certain angle, the first push plate 407 above is driven to lift for a certain height (taking the descending as an example), the descending of the first push plate 407 drives the lifting seat 413 to descend synchronously, under the self-gravity action of the two abutting seats 403, the inner curved surface just abuts against the positions of the shoulders and the chest cavity of the patient, at the moment, the pressure sensor 412 at the upper end of the guide rod 411 is pushed by the spring 414, the inner stress sensing value is certain, at the moment, the patient only needs to stare the light emitted by the light source 503 on one side with one eye, along with the operation, the frequency and the dropping amount of the injection pump 502 can be adjusted to intermittently provide liquid medicine or normal saline into the dropping swing head 504, the dropping amount, the volume and the dropping position of a single drop can be determined, and the appropriate flushing force can reduce the occurrence of eye discomfort in the operation process of a patient;

when the patient is too tense and unable to fit with the body or is too small in age, and the limb moves to a large extent in the operation process, the limb slightly overturns to drive the abutting seat 403 on one side (the left side is taken as an example) to upwards lift a certain distance, so that when the guide rod 411 is driven to synchronously lift, the abutting pressure of the spring 414 on the upper end pressure sensor 412 is inevitably reduced, at the moment, according to the data change of the pressure value of the pressure sensor 412, a signal is transmitted to the driving motor 401 to rotate the driving motor 401 by a certain angle (the push plate one 407 is also taken as an example) and to be positioned again, the process drives the swinging plate 409 to overturn by a certain angle around the hinge point with the lower push plate two 408 to drive the rotatable push rod 410 to descend, and then the dropping swing head 504 is driven by the rotating shaft 505 to rotate by a certain angle to the right, so that the liquid medicine or physiological saline dripped by the dropping head 504 can be obliquely dripped into the patient, the membrane opening and resetting positions in the operation area are avoided, the operation time is shortened, and the operation safety is improved.

Based on the above, according to the invention, the monitoring and control mechanism 3 is arranged on the operating table 1, the cornea dropping mechanism 4 is arranged on the monitoring and control mechanism 3, the output end of the driving motor 401 drives the swing rod 405 to rotate, the lifting seat 413 is driven to move downwards by the swinging piece 402, the second push plate 408 and the first push plate 407, so that the inner walls of the soft rubber curved surfaces of the two abutting seats 403 and a patient complete a positioning test, the frequency and the dropping amount of the injection pump 502 can be adjusted to intermittently provide liquid medicine or physiological saline into the dropping head 504, the dropping medicine drop metering, the single drop volume size and the dropping position can be determined, and the appropriate flushing force can reduce the occurrence of eye discomfort in the operation process of the patient;

through setting up in pressure sensor 412 on two guide bars 411, according to the data change that leans on pressure numerical value that receives spring 414, make its certain angle of rotation with signal transmission to driving motor 401, through swing board 409 push-and-pull push rod 410 synchronous lift, drive pivot 505 and rotate on installation section of thick bamboo 501, and then drive dropping liquid pendulum head 504 and carry out the same angle upset for the orbit, make the liquid medicine or the normal saline that dropping liquid pendulum head 504 dripped can obliquely drip into patient's intraocular, avoid the regional division membrane reset position of operation, accelerate operation time and improve the operation security.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
