Description

A new type of eyelid opener Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a novel eyelid opener. Background Technology

[0002] During ophthalmic surgery or eye examinations, it is often necessary to open the patient's eyelids so that the doctor can clearly observe the eyeball or perform surgical procedures. In the medical process, to prevent the patient's eyelids from closing, an eyelid opener is used to open the eyes to facilitate medical treatment.

[0003] Currently, in the prior art, for example, Chinese patent with announcement number CN213665448U discloses a novel eyelid opener for medical aesthetics. In the process of the support part opening the eyelid, the position of the support part is in an arc-shaped change state. However, the eyelid is generally in a horizontal opening change state during the opening process. The two cannot be fully matched, resulting in a decrease in the patient's comfort during the eyelid opening process. In view of this, a novel eyelid opener is proposed. Summary of the Invention

[0004] The main objective of this invention is to provide a novel eyelid opener that can solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention proposes a novel eyelid opener, comprising:

[0006] An elastic rod, used to provide a stretching force, wherein the elastic rod is a ring structure;

[0007] Connectors, mounted on the elastic rod, are used to connect other components;

[0008] The eyelid flap, connected to the connector, is used to abut against and open the eyelid.

[0009] Preferably, the elastic rod is an integral structure made of elastic material. By compressing the elastic rod, it contracts inward, causing the eyelid flap to contract. After the eyelid flap comes into contact with the eyelid, the elastic rod is released, and the eyelid flap opens the eyelid.

[0010] Preferably, the elastic rod is a two-set hinged structure, with the two sets of elastic rods connected by a hinge point. The angle formed by the two sets of elastic rods is between 130° and 180°. By compressing the two sets of elastic rods and rotating them around the hinge point, the elastic rods are driven to contract inward, causing the eyelid flap to contract accordingly. After the eyelid flap abuts against the eyelid, the elastic rods are released, and the eyelid flap opens the eyelid. The radius of curvature of the elastic rod is 30mm-40mm, and the length of the elastic rod is 26.95mm-36.95mm.

[0011] Preferably, the elastic rod is thickened at the position of the eyelid flap, and the elastic rod is widened at the deformation and stress position.

[0012] Preferably, the elastic rod of the integrated structure has a slot at the deformation point.

[0013] Preferably, the width of the connector is 1mm-6mm, the width of the eyelid flap is 6mm-16mm, the thickness of the eyelid flap is 6mm-10mm, the depth of the eyelid flap is 2mm-4mm, and the distance between the two sets of eyelid flaps is 17mm-22mm.

[0014] This utility model provides a novel eyelid opener. It has the following beneficial effects:

[0015] (1) The new eyelid opener provides elastic force through the elastic rod, which is simple in structure and easy to operate. It can quickly and effectively open the eyelid. At the same time, during the contraction and opening process, the two sets of eyelid flaps can be on the same straight line, so that the eyelid flaps fit the eyelids well and reduce the discomfort of the patient during the eyelid opening process.

[0016] (2) The new eyelid opener adopts a hinged or integrated elastic rod design, which can select different structures according to actual needs to meet diverse usage scenarios. The hinged elastic rod design makes it easier to pinch and quickly restore the original state. The integrated elastic rod design does not require assembly during the manufacturing process, which can reduce costs. Attached Figure Description

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please refer to Figures 1-3. This utility model proposes a novel eyelid opener, including an elastic rod 1, a connector 2, and an eyelid flap 3. The elastic rod 1 is used to provide the elastic force for opening. The elastic rod 1 has a ring structure. The connector 2 is disposed on the elastic rod 1 and is used to connect other components. The eyelid flap 3 is connected to the connector 2 and is used to abut against the eyelid and open the eyelid.

[0029] In this embodiment of the invention, the elastic rod 1 has two sets of hinged structures. The two sets of elastic rods 1 are connected by a hinge point, and the angle formed by the two sets of elastic rods 1 is between 130° and 180°. The angle of the elastic element is more in line with the curvature of the eye contour, which can avoid equipment interference during examination. By compressing the two sets of elastic rods 1 and rotating them around the hinge point, the elastic rods 1 are driven to contract inward, and the eyelid flap 3 contracts accordingly. After the eyelid flap 3 comes into contact with the eyelid, the elastic rod 1 is released, and the eyelid flap 3 opens the eyelid. At the same time, during the contraction and opening process, the two sets of eyelid flaps 3 can be on the same straight line, so that the eyelid flap 3 fits the eyelid well and reduces the discomfort of the patient during the eyelid opening process. The radius of curvature of the elastic rod 1 is 30mm-40mm, and the length of the elastic rod 1 is 26.95mm-36.95mm.

[0030] Furthermore, the surface of the eyelid flap 3 is provided with a soft padding layer made of silicone or rubber material, which is used to reduce friction between the eyelid flap 3 and the eyelid, reduce damage to the eyelid, and improve patient comfort.

[0031] Furthermore, the elastic rod 1 is thickened at the position of the eyelid flap 3, and the deformation and stress position of the elastic rod 1 is widened. In this way, the elastic rod 1 is made more durable.

[0032] Furthermore, please refer to Figure 5. The width of connector 2 is 1mm-6mm, and the width of eyelid flap 3 is 6mm-16mm to ensure patient comfort and suitability for eyes of different sizes. The thickness of eyelid flap 3 is 6mm-10mm to avoid interference from examination equipment. The depth of eyelid flap 3 is 2mm-4mm, and the distance between the two sets of eyelid flaps 3 is 17-22mm to ensure the eyelid opening effect.

[0033] Example 2

[0034] Based on Embodiment 1, please refer to Figure 4. The elastic rod 1 is an integral structure. The elastic rod 1 of the integral structure has a groove at the deformation point. The elastic rod 1 is made of elastic material. By compressing the elastic rod 1, the elastic rod 1 contracts inward, which drives the eyelid flap 3 to contract. After the eyelid flap 3 comes into contact with the eyelid, the elastic rod 1 is released, and the eyelid flap 3 opens the eyelid. The use of the groove does not hinder the inward contraction of the elastic rod 1.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
