Description

Technical Field

[0001] The utility model relates to the field of medical auxiliary equipment, in particular to a double eyelid fine locator. Background Art

[0002] Double eyelid surgery, also known as blepharoplasty, is a common cosmetic surgery that aims to change the shape of the eyelids to create a distinct layer of skin folds, i.e. double eyelids, to enhance the appearance of the eye. This surgery is usually performed on people with single eyelids, or those who have double eyelids but they are not obvious enough, have loose eyelids, or have other eye problems. The position, width, and shape of the double eyelids directly affect the appearance of the eyes and the overall facial balance. If the surgical position is not positioned properly, the double eyelids may be too wide or too narrow, affecting the natural appearance of the eyes, so it needs to be carefully positioned before the surgery.

[0003] Traditional fine positioning relies more on the experience of doctors, but this experience is not universal, and the risk of surgery for patients is increased. The utility model patent with the publication number CN215937711U optimizes the above problems. The prior art includes a main body, the inner wall surface of the main body is fixedly connected with a positioning slide rail, the outer surface of the positioning slide rail is sleeved with two positioning rods, a side surface of the main body is provided with a slide groove, one end of the two positioning rods passes through the inside of the slide groove, and a two-way threaded rod is threadedly connected to the side surface of the two positioning rods. Bearings are embedded on both sides of the main body. The utility model turns the handle to move the two positioning rods to the top of the patient's two pupils, and then turns the first knob bolt to adjust the relative positions of the two positioning rods, two support rods, four sliding sleeves and two rotating shafts to adapt to the patient's face shape, and then pushes one end of the two support rods with the two rotating shafts as the center of the circle, so that the marking pen draws a symmetrical arc on the patient's eyelids, ensuring the accuracy of marking, and can adapt to patients with different face shapes, with a wide range of applications.

[0004] However, there is still room for improvement in this existing technology:

[0005] In the prior art, the designed positioning device lacks a supporting structure, which means that the doctor needs to hold the device and cover it on the patient's face to operate. During this process, the doctor's elbows are suspended in the air for a long time. On the one hand, the doctor's elbows are under increased pressure, making them prone to fatigue and increasing the doctor's burden. On the other hand, long-term suspension in the air will weaken the doctor's control over the elbows, resulting in hand tremors and errors, increasing the risk of surgery.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1:

[0032] like Figures 1-2 As shown, the present embodiment proposes a double eyelid fine locator, which mainly includes a base 1, a hand rest 5, a face positioning member 8, and a fine positioning structure 14, wherein the base 1 is arranged as two side by side and used in cooperation with each other, for supporting on the bed on which the patient lies, the top of the base 1 is fixedly connected with an outer leg 2 which is hollow inside and open upward, and an inner leg 3 is arranged inside, and the outer leg 2 and the inner leg 3 are connected to each other by a lifting structure 4; the bottom end of the hand rest 5 is fixedly connected with a bearing part 6, and the bottom end bearing of the bearing part 6 is connected with a bearing block 7, and the bearing block 7 is fixedly connected to the top of the inner leg 3; the hand rest 5 can be used to place the doctor's elbow, and can be rotated according to the usage to meet the operation requirements. When in use, the doctor can operate the lifting structure 4 according to his own usage, thereby adjusting the height of the hand rest 5.

[0033] Next, the above-mentioned face positioning member 8 is arranged in the middle of the two hand rests 5 on both sides, and a positioning groove 9 is opened therein, which is adapted to the size of the patient's face. When in use, the doctor must adjust it to the top of the patient's face before it can be positioned, and the front end of the face positioning member 8 is plugged with a laterally arranged positioning rod 10, and the positioning rod 10 is fixedly connected to the top of the side where the outer legs on both sides are close to each other, and the rear end of the face positioning member 8 is threadedly connected with a screw rod 11, and both sides of the screw rod 11 are rotatably connected with a connecting seat 12, and the connecting seat 12 is fixedly connected to the rear end top of the outer leg 2, and the bottom front of the connecting seat 12 and the upper rear end of the outer leg 2 are connected to each other by a support block 13; at the same time, motors 15 are arranged on both sides of the screw rod 11, and the output shaft of the motor 15 passes through the connecting seat 12 and is fixedly connected to the screw rod 11, and the bottom end of the motor 15 is fixedly connected with a motor seat 16, and the motor seat 16 is fixedly connected to the connecting seat 12.

[0034] Therefore, when the motor 15 is powered on, its output shaft drives the screw 11 to rotate. Under the influence of the threaded connection, the face positioning member 8 is rotated by force, and the positioning rod 10 stabilizes the center of the face positioning member 8 so that it does not collapse. The fine positioning structure 14 is arranged inside the positioning groove 9. The bottom end of the face positioning member 8 is provided with an arc-shaped face placement groove 35, and the groove is connected to the face positioning member 8, which is used to adapt to the patient's face shape. The inside of the face placement groove 35 is fixedly connected with a silicone part 36, which can provide the patient with a skin-friendly and comfortable texture and increase the friction of contact.

[0035] Embodiment 2:

[0036] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

A latch tooth 26 that is meshed with the gear ring 22 is rotatably connected to the fixing block 25, and a crank handle 27 is fixedly connected to the front bottom end of the sleeve 24.

[0038] Therefore, when it is necessary to adjust the lifting structure 4 to rise, the doctor must move the latch tooth 26 to make it rotate counterclockwise and engage with the gear ring 22, and then press down the crank handle 27 forcefully to make the crank handle 27 rotate clockwise. The gear ring 22 then rotates synchronously under the engagement of the latch tooth 26, driving the spiral engaging portion 21 thereafter to rotate clockwise. At this time, the rack 17 rises under the action of the spiral engaging portion 21, realizing the rising of the inner leg 3 relative to the outer leg 2, and completing the lifting operation. When it is necessary to adjust the lifting structure 4 to fall, the above operation can be repeated in reverse.

[0039] Embodiment 3:

[0040] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

When in use, the positioning groove 2 30 in the left eye positioning member 28 and the right eye positioning member 29 is used to place the patient's eyes. The patient must lie down with his eyes closed before the operation can continue, and the front and rear ends of the right eye positioning member 29 are respectively provided with a screw member 1 31 and a screw member 2 32 with a twist handle, and the screw member 1 31 and the screw member 2 32 are arranged in opposite directions. Specifically, the adjacent sides of the screw member 1 31 and the screw member 2 32 are provided with a smooth portion 33, and the separated sides of the screw member 1 31 and the screw member 2 32 are provided with a threaded portion 34, and the separated sides of the screw member 1 31 and the screw member 2 32 pass through the face positioning member 8. The threaded portion 34 of the first threaded member 31 is threadedly connected to the right eye positioning member 29, and the smooth portion 33 of the first threaded member 31 is inserted into the left eye positioning member 28. The threaded portion 34 of the second threaded member 32 is threadedly connected to the left eye positioning member 28, and the smooth portion 33 of the second threaded member is inserted into the right eye positioning member 29.

[0042] Therefore, when the doctor wants to adjust the relative positions of the left eye positioning member 28 and the right eye positioning member 29, he turns the handle on the threaded member 1 31 or the threaded member 2 32 next to it, and the left eye positioning member 28 and the right eye positioning member 29 move under the influence of the threaded connection, and finally the adjustment is achieved.

[0043] It should be specially noted here that the components described and identified in the text and drawings of the utility model are the key components constituting the utility model, and the remaining non-key components or obvious prior art components, such as screws, nuts and other connectors, and technical features similar to the prior art are not shown.

[0044] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
