A branch fixing head 522 having a fixed end connected to the free end of the second arm 52 and a free end to which the fixing head is attached is provided at the free end of the second arm 52. The free end of the second arm 52 is connected to the fixed end of the branch fixing head by a third angle adjusting device 57, and the third angle adjusting device 57 has the same structure as the first and second angle adjusting devices, and will not be described herein again. The adjustment of the downward pressure balance of the two branch fixing heads is achieved by the third angle adjustment device 57.

The various sensors and the motor device are connected with an external controller through data lines.

The following describes the control method of the automatic fixation device for outer canthus formation of eye in detail, and the control is realized by an external controller. The driving components (such as a motor or an air pressure driving rod and the like) of the lifting module 2, the translation module 3, the image acquisition module 4 and the eye fixing module 5, as well as various sensors and image acquisition devices are connected to an external controller through data lines, and the external controller can be a PC (personal computer), an upper computer or other computer equipment.

The control method of the automatic fixation device for the outer canthus formation of the eye comprises the following steps:

firstly, the translation module 3 is driven to horizontally extend out of a preset length distance, and the image acquisition module 4 is started to extract the eyelid fissure length L and the eyelid fissure maximum width W of an operator through an image recognition technology. The lid fissure aspect ratio W/L was calculated. The horizontal distance between the fixing heads 511 of the first arm 51 and the fixing heads 5222 of the second arm 52 is adjusted by driving the sliding bush 53 and the sliding rail 54 of the coupling ends of the first arm 51 and the second arm 52 in conjunction with the module. When the W/L is less than 0.55, the horizontal distance between the fixed head 511 of the first arm 51 and the fixed head 5222 of the second arm 52 is adjusted to be the eye fissure length L + S1, wherein the value range of S1 is 8-10 mm; when W/L is larger than 0.55, the horizontal distance between the fixing head 511 of the first arm 51 and the fixing head 5222 of the second arm 52 is adjusted to be the length L + S2 of the eye fissure, wherein the value of S2 ranges from 3 mm to 5 mm. This is because if the length and width of the palpebral fissure is small, the eye shape is relatively narrow, and in the subsequent opening process of the outer canthus, a longer opening needs to be cut and a larger angle needs to be kept, so the second end fixing head needs to keep a relatively longer distance from the outer canthus; on the contrary, if the length and width of the palpebral fissure is large, the eye is relatively round, and the angle does not need to be kept large in the subsequent opening process of the outer canthus, so the second fixing head is kept relatively close to the outer canthus.

Third, the rotatable post 11 is driven to rotate and the lifting module 2 and the translation module 3 are driven to move relatively, and the image capturing module 4 is turned on to perform feedback control through an image recognition technology, so that the fixed head 511 of the first arm 51 falls within a predetermined range outside the medial canthus of the eye, preferably, within a square area 5mm × 5mm outside the medial canthus of the eye or a circular area 5mm in diameter. The lifting module 2 is driven to descend until the pressure sensor on the fixing head of at least one of the first arm and the second arm can sense the pressure value, namely the fixing head of at least one of the first arm and the second arm contacts with the eye skin tissue, the driving motion is stopped, and the position of the fixing head 511 of the first arm is fixed.

Fourthly, the motor of the first angle adjustment device 55 is driven to rotate the fixing head 511 at the free end of the first arm 51 downwards or upwards through the rotation of the internal gear of the first angle adjustment device 55, so as to gradually increase or decrease the pressure, so that the fixing head of the first arm 51 provides a predetermined pressure to the inner canthus skin, that is, the value of the pressure sensor on the fixing head 511 of the first arm 51 reaches a predetermined value. Preferably, the predetermined value may be between 50-80N. The above values can ensure fixation to the inner canthus eye tissue, thereby providing stable fixation to the whole eye when reshaping the eye curve.

And fifthly, the motor of the second angle adjusting device 56 is driven to drive the fixing heads 5222 at the free ends of the second arms 51 to rotate downwards through the rotation of the gears inside the second angle adjusting device 56 until the pressure sensors on the two fixing heads 5222 on the second arms can sense pressure values, namely, the two fixing heads 5222 on the second arms are both contacted with the skin tissues of the eyes, and the driving motion is stopped. At this time, the release adhesive layers on the outer layers of the two fixing heads 5222 are adhered to the skin, and quantitative measurement of skin strain can be made.

Sixthly, the two transmission gears in the fixed disk 58 are driven to drive the two surface gears 5223 to rotate, so that the two branch brackets 5221 are opened and closed in the horizontal plane. Specifically, when the W/L of the predetermined position is less than 0.55, the included angle between the two branch brackets 5221 is controlled to be 50-60 degrees; when the W/L is greater than 0.55, the included angle between the two branch brackets 5221 is controlled to be 40-50 degrees, and the strain of the strain gauges on the two fixing heads is not more than 15%. The control can ensure that the canthus skin is well fixed in a targeted manner according to different eye types.

Seventh, the second angle adjustment device 56 is driven by the motor to rotate the branch support 5221 downwards or upwards through the gear inside the second angle adjustment device 56, so as to gradually increase or decrease the pressure, so that the branch support 5221 of the second arm 52 provides a predetermined pressure to the outer canthus skin, preferably, the predetermined pressure may be between 25N and 40N measured by the pressure sensor on the branch support 5221. The above values can ensure fixation to the outer canthus eye tissue, thereby providing stable fixation to the whole eye when reshaping the eye curve.

Eighth, the third angle adjusting device 57 is driven by the motor, and the gears inside the third angle adjusting device 57 drive the two branch supports 5221 to rotate, so that the pressure of the fixing heads on the two branch supports 5221 is distributed. The third angle adjusting means 57 is driven by a motor to make the lower eyelid fixing head measure a pressure 1.1 to 1.3 times that of the upper eyelid by realizing the integral rotation of the fixing heads on the two branch brackets 5221. This is due to the fact that the lower eyelid is relatively loose in skin relative to the upper eyelid and the need to provide a higher fixation force.

After the eighth step, completing the preoperative fixation of the ocular fixation device, the method further comprises:

and ninthly, monitoring in real time through strain gauges on two fixing heads of the second arm 52 in the operation, and alarming when the strain of the upper eyelid exceeds 27% and the strain of the lower eyelid exceeds 36%. Early warning may cause excessive stress on the eyelid after operation, which further causes eversion of the eyelid.

Since both eyes have symmetry, the embodiment of the invention is only schematically illustrated for one eye, and for the fixation of the other eye having symmetry, the symmetry problem can be solved by using another fixation means that is mirror-symmetrical to the direction in the implementation or by making the fixation means detachably mounted on the translation module, inverting the fixation means when switching eyes.
