Description

Technical Field

[0001] The present invention relates to the technical field of corneal astigmatism axis markers, in particular to an intelligent corneal astigmatism axis marker. Background Art

[0002] Corneal astigmatism axis marking refers to the process by which the doctor locates and marks the astigmatism axis on the patient's cornea before performing toric intraocular lens surgery. During subsequent surgery, changes in the patient's posture may cause relative eye movement, necessitating accurate surgery based on the astigmatism axis marking. Because toric intraocular lens surgery requires extremely high surgical precision, accurate marking of the astigmatism axis, a key foundation for the entire procedure, is crucial.

[0003] In the prior art, the method for marking and positioning the corneal astigmatism axis is that the medical staff uses one hand to hold open the patient's eyelids, then expose the patient's eyeball, and then let the patient focus his vision on the astigmatism axis measuring instrument, and then use the other hand to bring the astigmatism axis measuring instrument close to the patient's eyeball until it reaches the target position. Then the medical staff releases the hand holding the patient's eyelid, and then uses the hand to hold the marking instrument to mark, and uses a sterile marking pen to mark the astigmatism axis at the level of the corneal margin according to the measurement results displayed by the measuring instrument before the operation, and then uses the tip of a 1ml needle to draw a certain depth in the corneal epithelium for scale marking.

[0004] At present, the existing technology requires the hand that fixes the eyelid to be released to make the mark, which may easily cause the patient's eyelid to close again during the marking, hindering the marking behavior. The existing technology relies on medical personnel to manually operate the instrument and cooperate with the measuring instrument to mark the astigmatism axis. It is necessary to keep the eyelid open, use the measuring instrument, and make high-precision markings. The requirements for the medical personnel's operating proficiency and accuracy are too high. The high-precision marking performed by hand is prone to large errors, which may lead to inaccurate measurement mark position and failure of subsequent surgery. It is even impossible to control the strength of the manual marking, so the mark is inserted too deeply and injure the cornea. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to propose an intelligent marking instrument for the axis of corneal astigmatism, so as to solve the problem that there is no intelligent marking instrument in the prior art that can simultaneously achieve stable maintenance of the patient's eye opening limit and high-precision measurement and marking of the corneal astigmatism axis with an automated structure, resulting in manual eye opening and measurement marking operations being very complicated, and large marking errors leading to surgical failure.

The output end of the first adjustment servo motor passes through the first fixed plate and is fixedly connected to the first adjustment screw. A first inspection plate 21 is fixedly installed in the middle of the upper end of the upper box.

[0041] The pupil recognition rangefinder includes a columnar body, an infrared rangefinder 29 and a pupil recognition camera 30. The pupil recognition camera is fixedly arranged at the center of the front of the output end of the columnar body. The infrared rangefinder surrounds the pupil recognition camera and is fixedly arranged on the front of the output end of the columnar body. Eyelid spreaders 37 are fixedly arranged at the upper and lower ends of the outer side of the infrared rangefinder. The eyelid spreader consists of a fixed distance telescopic rod and an arc-shaped spreader pad fixedly arranged at the top of the fixed distance telescopic rod. A marking notcher 38 is fixedly arranged around the outer side of the columnar body. The marking notcher consists of a circular surrounding sliding frame and a sliding frame arranged on the circular surrounding sliding frame. The internal telescopic marking sleeve is composed of a circular surround sliding frame which is sleeved on the outside of the columnar body and coaxial with the circular track frame. The telescopic marking sleeve is a telescopic round rod equipped with a marking notch structure. The telescopic marking cylinder can be driven by the motor connected to it to move around in a circle in the circular surround sliding frame, and the telescopic marking sleeve can rotate under the action of the rotating motor to adjust the posture of the marking head. A sliding marking groove 39 is provided on the front of the telescopic marking cylinder, and a marking notch integrated engraving needle 40 is provided inside the sliding marking groove. The marking notch integrated engraving needle can slide in the sliding marking groove driven by the motor.

[0042] A fixing frame 9 is fixedly provided on the front of the upper box body, an electric slide rail 8 is fixedly provided on the fixing frame, a second electric slider 7 is slidingly provided at the upper side of the electric slide rail, a lower pressure plate 14 is fixedly provided between the second electric sliders, a first electric slider 5 is slidingly provided at the lower side of the electric slide rail, a supporting plate 20 is fixedly provided between the first electric sliders, a square groove 16 is provided at the front end of the upper box body, and soft pads 15 are fixedly provided at the bottom end of the lower pressure plate and the upper end of the supporting plate.

[0043] The central processor of the intelligent control center is connected to all the electronic control devices of the entire device through lines.

[0044] In this embodiment, the device is first started. When the patient arrives in front of the intelligent marking instrument, the device is started. The horizontal instruction is first input through the control panel, so that the second adjusting servo motor on the base drives the second adjusting screw in the limiting slide groove to rotate under the control of the central processor, thereby driving the adjusting rod to move up and down. Finally, when the instrument state monitored by the spirit level is horizontal, the second adjusting servo motor is stopped. When the instrument is level, the lifting instruction is input to the control panel so that the central processor controls the electric lifting rod to drive the upper box to move downward to find the patient's eyes. When the square groove of the marking instrument is aligned with the eyes, the electric lifting rod is stopped, and then the patient's head is placed on the fixed The patient's head is positioned in this posture on the stand by adjusting the electric slider, and then the control panel is input with a fixed mark notch instruction, so that the central processor controls the pupil positioning component to perform pupil positioning, that is, controls the first adjustment servo motor to operate, thereby driving the first adjustment screw to rotate, so that the pupil recognition rangefinder connected to the first adjustment screw through the threaded sleeve and the connecting block moves horizontally. When the pupil recognition camera in the pupil recognition rangefinder captures the pupil data, it is adjusted so that the pupil recognition camera is aimed at the patient's pupil, and then the infrared rangefinder is used to measure the distance between the instrument and the eye, and the obtained data is fed back to the central controller. The central controller controls the eyelid stretcher to extend a certain distance according to the feedback distance data, so that the eyelid stretcher can reach the eyelid and support the eyelid by moderately squeezing the eyelid, thereby avoiding the eyelid closure hindering the operation during subsequent operations. After the eyelid support is completed, the marking instruction is input according to the imaging data. The central controller will drive the telescopic marking sleeve to slide in the circular sliding frame to the front of the to-be-marked area, and then rotate the telescopic marking sleeve so that the sliding marking groove at its head can be rotated to the axial range for corneal marking. After the adjustment is completed, the marking depth value and the marking length value are set according to the distance data fed back by the infrared rangefinder. Under the control of the motor, the telescopic marking cylinder is extended and retracted until the depth of the marking needle into the cornea is equal to the set value, and then the marking needle is made to slide the set length in the sliding marking groove to complete the marking and complete the operation.

[0045] When marking, the pupil recognition camera will monitor in real time whether the pupil is still aligned. If the eyeball is offset, the control center will make adaptive adjustments and wait until the posture returns to normal before marking again.

[0046] This embodiment proposes an intelligent marking instrument that uses an automated structure to simultaneously achieve stable maintenance of the patient's eye opening limit and high-precision measurement and marking of the corneal astigmatism axis. The entire device is controlled by an intelligent control center for operation, so that all operations are completed by the mechanical structure, simplifying the marking and notching operation of the astigmatism axis, improving the accuracy of the operation, and ensuring that the astigmatism axis is accurately marked. The setting of the eyelid retractor is conducive to stably exposing the eyeball and ensuring the smooth progress of subsequent operations. The positioning accuracy is greatly improved by combining infrared ranging with pupil camera positioning. The setting of the integrated marking and notching needle is conducive to the simultaneous completion of marking and notching to avoid increased errors caused by secondary operations, thereby greatly improving the success rate of subsequent operations.

[0047] The device's pupil distance adaptation adjustment structure is composed of a first adjustment servo motor, a first adjustment screw, a threaded sleeve, and a marker. In this structure, the first adjustment servo motor can drive the first adjustment screw to rotate, thereby completing the position adjustment of the threaded sleeve, and then completing the position adjustment of the marker. The overall structural design enables the device to adjust the distance between a pair of markers according to the different pupil distances of users with different pupil distances, and the design of a pair of markers has higher working efficiency than the traditional single marker.

[0048] The adjustable head support structure of the device is composed of an electric lifting rod, an electric slide rail, a first electric slider, a second electric slider, a lower pressure plate and a support plate. In this structure, the electric lifting rod can adjust the measuring height of the device according to the sitting height of different users. The first electric slider can control the first electric slider to adjust its position through the electric slide rail when the user's head is placed on the support plate. When it is adjusted to the height of the user's eyes at the height of the marker, the second electric slider will be controlled to adjust its position on the electric slide rail, so that the lower pressure plate is pressed down to the top of the user's head to limit the position of the user's head. The overall structural design allows the device to be adaptively adjusted for users with different face shapes and heights, greatly improving the user experience and making the device suitable for a wider range of people.

[0049] The device's rapid horizontal adjustment structure is formed by the second adjusting motor, second adjusting screw, adjusting rod and spirit level. In this structure, the second adjusting motor conveniently drives the second adjusting screw to rotate, so that the adjusting rod threadedly matched with the second adjusting screw changes its position under the action of the rotating second adjusting screw. The spirit level conveniently determines the inclination angle of the base through the position of the bubble in the spirit level, and facilitates rapid horizontal correction. The overall structural design allows the device to be quickly adjusted to a horizontal state with the assistance of the spirit level after placement. The device that ensures a horizontal state can ensure that the user ensures the alignment of the position when marking the astigmatism axis, thereby further improving the accuracy of the astigmatism axis marking.

[0050] In this embodiment, the top of the eyelid retractor is a silicone arc head. By setting the contact head that contacts the eyelid part to a silicone arc head, it is beneficial to achieve flexible support to avoid damage to the eyes, and the silicone can provide greater friction to ensure that the eyelid will not slide closed.

[0051] In this embodiment, the sliding mark groove is a rectangular deep groove. When the sliding mark groove is rotated to point to the pupil recognition camera, the distance from the edge of the sliding mark groove to the center of the pupil recognition camera is set to be smaller than the smallest distance from the corner of the eye to the pupil of humans that has been discovered. By limiting this length, it is helpful to ensure that for any patient, when the pupil recognition camera is aligned directly with the pupil, the sliding mark groove after rotation and alignment can cover the inside of the corner of the eye, thereby ensuring that subsequent marking and notching can be carried out.

[0052] In this embodiment, the marking and scoring integrated needle can slide parallel to the inside of the sliding marking groove by being controlled by a motor in the sliding marking groove, which is helpful to ensure that the cornea can be marked and scored in parallel.

[0053] In this embodiment, the telescopic marking cylinder can be rotated under the drive of the rotary motor, which is conducive to driving the sliding marking groove to rotate and avoid interference with other structures.

[0054] In this embodiment, the marking and scoring integrated scoring needle has a structure in which the outer layer is a marking pen and the inner layer is a scoring needle, wherein the scoring needle is 30-50 microns higher than the outer marking pen layer.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
