Description

Technical Field

[0001] The present invention relates to the field of ophthalmic surgical devices, and in particular to an ophthalmic surgical auxiliary device. Background Art

[0002] Currently, ophthalmic surgeries performed clinically generally require the patient's eyelids to be held open for surgical procedures. Existing techniques often utilize eyelid retractors. Conventional eyelid retraction involves clamping the eyelid with a clip and then pulling it outward. Clamping the eyelid with a clip requires medical personnel to manually apply a small clamp to different locations on the eyelid, a process that is inconvenient and slow. The clamp's grip on the eyelid cannot be too strong; excessive grip can cause injury. However, if the clamp's grip is too weak, the clip can easily fall off during the process of stretching the eyelid. If the eyelid falls off the clip during surgery, it can also hinder the procedure. Some eyelid retractors also utilize a patch that directly adheres to the eyelid and then pulls it outward. This patch relies on adhesive to hold the eyelid in place, but this method of retraction also carries the risk of eyelid detachment.

[0003] However, for some special patients, such as those with conjunctival sac scars, deformities, shallow curvature, large eyelids, and small eyeballs, it is difficult to open the eyelids using conventional eyelid speculum, which is time-consuming and labor-intensive, greatly increasing the difficulty of the surgeon's work. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an ophthalmic surgical auxiliary device that can effectively expand and stretch the patient's eyelids so that the patient's eyelids are stably held open, the eyelids are not easily fallen off, and the normal operation of the operation can be ensured.

[0005] In order to achieve the above object, the technical solution provided by the present invention is:

[0006] An ophthalmic surgical auxiliary device includes a mounting ring, on which two groups of eyelid expansion and stretching components are symmetrically arranged. Each group of eyelid expansion and stretching components includes multiple eyelid expansion and stretching units. The length directions of the multiple eyelid expansion and stretching units are parallel to the radial direction of the mounting ring. The multiple eyelid expansion and stretching units are arranged at equal intervals on the mounting ring. The eyelid expansion and stretching units include a radial adjustment mechanism installed on the mounting ring, and an eyelid eversion stretching mechanism is provided on one end of the radial adjustment mechanism facing the center of the mounting ring.

[0007] Specifically, the radial adjustment mechanism includes a rectangular blind hole opened on the inner side of the mounting ring, the length direction of the rectangular blind hole is parallel to the radial direction of the mounting ring, a rectangular rod is slidably inserted in the rectangular blind hole, and a screw corresponding to the rectangular rod is rotatably connected to the mounting ring, and the screw is threadedly connected to the rectangular rod.

[0008] Specifically, one end of the screw rod extends to the outside of the mounting ring, and a screw cap is fixed on the end of the screw rod outside the mounting ring.

[0009] Specifically, the eyelid eversion stretching mechanism includes a dual-axis motor, which is fixed on one end of a rectangular rod facing the axis of the mounting ring. Support plates are fixed on both output shafts of the dual-axis motor. Two electric rollers are installed between the two support plates. The two electric rollers are connected by belt transmission. A mounting plate is fixed on the belt below the electric roller. An adhesive patch is fixed to the lower end of the mounting plate. The upper end of the support plate is elastically and slidably connected to the eyelid clamping mechanism.

[0010] Specifically, the eyelid clamping mechanism includes a movable plate, two connecting plates perpendicular to the movable plate are fixed at the lower end of the movable plate, a T-shaped slider is fixed at the lower end of the connecting plate, a T-shaped slot is provided at the upper end of the support plate, the T-shaped slider is slidably engaged in the T-shaped slot, a spring is installed in the T-shaped slot, one end of the spring is tightly against the T-shaped slider, and the other end of the spring is tightly against the slot wall of the T-shaped slot, an upper motor is fixed at the upper end of the movable plate, and a splint is fixed on the output shaft of the upper motor.

[0011] Specifically, a soft rubber pad is installed at the lower end of the mounting ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When clamping the patient's eyelid, the present invention first folds the patient's eyelid, and then clamps the folded eyelid portion with a splint. This ensures that the eyelid will not separate from the eyelid eversion stretching mechanism during the subsequent stretching process to open the eyelid, ensuring a smooth operation.

[0014] 2. This device is simple and quick to operate when fixing the eyelid, and has good fixation. Compared with other devices, the final fixation state of this device is to clamp the edge of the eyelid and stretch it outward, so that the eyeball can be fully exposed, which is convenient for subsequent surgical operations.

[0015] 3. After the eyelid is stabilized by the eyelid eversion stretching mechanism, the eyelid can be expanded outward by the eyelid eversion stretching mechanism, thereby separating the eyelid from the eyeball, making it easier to perform eye surgery. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1 As shown, an ophthalmic surgical auxiliary device includes a mounting ring 1, with a soft rubber pad 2 installed at the lower end of the mounting ring 1. Two groups of eyelid expansion and stretching components are symmetrically arranged on the mounting ring 1. Each group of eyelid expansion and stretching components includes a plurality of eyelid expansion and stretching units. The length direction of the plurality of eyelid expansion and stretching units is parallel to the radial direction of the mounting ring 1, and the plurality of eyelid expansion and stretching units are arranged at equal intervals on the mounting ring 1. The eyelid expansion and stretching units include a radial adjustment mechanism installed on the mounting ring 1. An eyelid eversion stretching mechanism is provided on one end of the radial adjustment mechanism facing the center of the mounting ring 1.

[0024] like Figure 1 and Figure 2 As shown, the radial adjustment mechanism comprises a rectangular blind hole defined within the inner side of the mounting ring 1, with its length parallel to the radial direction of the mounting ring 1. A rectangular rod 15 is slidably inserted into the hole. A screw 16 corresponding to and threadedly connected to the mounting ring 1 is rotatably connected to the mounting ring 1. One end of the screw 16 extends outside the mounting ring 1, and a screw cap 17 is secured to the outer end of the screw 16.

[0025] like Figure 2 、 Figure 3 and Figure 4 As shown, the eyelid eversion stretching mechanism includes a dual-axis motor 14, which is fixed to one end of a rectangular rod 15 oriented toward the axis of the mounting ring 1. Support plates 7 are fixed to both output shafts of the dual-axis motor 14. Two motorized rollers 4 are mounted between the two support plates 7, connected by a belt 3. A mounting plate 5 is fixed to the belt 3 below the motorized rollers 4, with an adhesive patch 6 attached to its lower end. The eyelid clamping mechanism is elastically and slidably connected to the upper end of the support plate 7.

[0026] like Figure 4 and Figure 5As shown in the figure, the eyelid clamping mechanism includes a movable plate 9. Two connecting plates 10 perpendicular to the movable plate 9 are fixed to the lower end of the movable plate 9. A T-shaped slider 11 is fixed to the lower end of the connecting plate 10. A T-shaped chute 8 is formed at the upper end of the support plate 7. The T-shaped slider 11 is slidably clamped in the T-shaped chute 8. A spring is installed in the T-shaped chute 8. One end of the spring abuts against the T-shaped slider 11, and the other end of the spring abuts against the groove wall of the T-shaped chute 8. Under the elastic force of the spring, the movable plate 9 and the clamping plate 12 can maintain a state close to the mounting plate 5 and the adhesive patch 6. After the adhesive patch 6 adheres to the patient's eyelid and moves above the belt 3, the clamping plate 12 can timely clamp the eyelid adhered by the adhesive patch 6. An upper motor 13 is fixed to the upper end of the movable plate 9, and a clamping plate 12 is fixed to the output shaft of the upper motor 13.

[0027] When the device is in use, the mounting ring 1 is positioned and fixed above the patient's eye, so that the soft rubber pad 2 at the lower end of the mounting ring 1 contacts the skin outside the patient's orbicularis oculi muscle. Make the patient's eye correspond to the inside of the mounting ring 1. And make the two eyelid expansion and stretching members correspond to the upper eyelid and the lower eyelid above the patient's eye.

[0028] Rotate the cap 17, the cap 17 drives the screw 16 to rotate, and then makes the rectangular rod 15 slide along the radial direction of the mounting ring 1. Adjust the position of the adhesive patch 6 according to the contours of the upper eyelid and the lower eyelid above the patient's eye. Make the adhesive patch 6 correspond to the upper eyelid and the lower eyelid above the patient's eye. Then, start the double-shaft motor 14, and the double-shaft motor 14 drives the support plate 7 to rotate through its output shaft. The support plate 7 drives the electric roller 4, the belt 3, and the mounting plate 5 to rotate and move closer to the eyelid.

[0029] Start the electric roller 4. After the electric roller 4 rotates, the belt 3 can drive the mounting plate 5 to adjust its position. By controlling the movements of the cap 17, the double-shaft motor 14, and the electric roller 4, the adhesive patch 6 can be adhered to the edge of the patient's eyelid.

[0030] After that, start the electric roller 4. The electric roller 4 drives the mounting plate 5 to move towards the outside of the mounting ring 1 through the belt 3. When the mounting plate 5 is located above the belt 3 from below the belt 3, the edge of the eyelid is folded 180 degrees, that is, eyelid eversion.

[0031] Then, during the process of the mounting plate 5 moving towards the outside of the mounting ring 1 above the belt 3, when the mounting plate 5 contacts the movable plate 9, turn off the electric roller 4 and start the upper motor 13. The upper motor 13 drives the clamping plate 12 to rotate. The cooperation between the clamping plate 12 and the mounting plate 5 can clamp the folded part of the eyelid. Then start the electric roller 4 again, and then use the belt 3 to pull the clamped eyelid outwards. When the eyelid is stretched to a sufficient degree for surgery, turn off the electric roller 4 and then surgery can be performed.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
