Description

Technical Field

[0001] This utility model relates to the field of eyelid opener technology, and in particular to a novel ophthalmic surgical eyelid opener with water spray. Background Technology

[0002] Ophthalmic surgery is an important branch of medicine, and its technology has continuously advanced over the years through development and innovation. From simple surgical procedures such as cataract removal and wound suturing, to today's precision treatments using high-tech methods, ophthalmic surgery has made significant progress. Especially in recent years, with the application of laser technology and microsurgery, ophthalmic surgery can now achieve more precise and safer procedures, providing patients with better treatment outcomes.

[0003] As an indispensable medical device in ophthalmic surgery, the main function of the eyelid speculum is to open the patient's eyelids so that the doctor can clearly see the surgical site and perform precise operations. However, in some surgeries that take a long time, it is often necessary to regularly drip water into the patient's eyes to keep them moist, reduce friction and discomfort, and prevent corneal dryness and damage. This operation takes up a lot of surgical time. Based on this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a new ophthalmic surgical eyelid speculum that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel ophthalmic surgical eyelid retractor includes a support rod and further comprises: a rotating arm rotatably connected to the support rod, a connecting rod rotatably connected to the rotating arm, and a lifting support rod rotatably connected to the connecting rod; an eyelid retractor clamp is fixedly connected to the rotating arm, the eyelid retractor clamp is connected to an infusion tube, and the eyelid retractor clamp has an outlet hole; when the rotating arm is opened, the flow rate of the infusion tube increases, and when the rotating arm is closed, the flow rate of the infusion tube decreases.

[0007] Preferably, the support rod is connected to a threaded rod by a thread, the threaded rod is hollow, and the threaded rod is rotatably connected to the lifting support rod.

[0008] Furthermore, a sealing ring is fixedly connected to the threaded rod, and a rotating plug is rotatably connected to the threaded rod, the rotating plug being connected to the infusion tube.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: Refer to Figures 1-5 A novel ophthalmic surgical eyelid speculum includes a support rod 1, and further includes: a rotating arm 11 rotatably connected to the support rod 1, a connecting rod 31 rotatably connected to the rotating arm 11, and a lifting support rod 3 rotatably connected to the connecting rod 31; an eyelid speculum clamp 4 is fixedly connected to the rotating arm 11, the eyelid speculum clamp 4 is connected to an infusion tube 32, and an outlet hole 41 is provided on the eyelid speculum clamp 4; when the rotating arm 11 is opened, the flow rate of the infusion tube 32 increases, and when the rotating arm 11 is closed, the flow rate of the infusion tube 32 decreases.

[0027] In this utility model, by moving the lifting support rod 3, the connecting rod 31 is rotated. When the connecting rod 31 rotates, it pushes the rotating arm 11 outward or pulls it inward, thereby adjusting the opening and closing of the rotating arm 11.

[0028] The eyelid clip 4 is hollow inside and is connected to the infusion tube 32. The infusion tube 32 can be connected to an external infusion bag or infusion bottle. The medicine or water flows into the patient's eye through the infusion tube 32 and the eyelid clip 4 from the water outlet 41.

[0029] Because the eye size varies among different age groups and people, the angle at which the eyelid clamp 4 opens also varies, and the amount of medicine or water that needs to be dripped into the eye also varies. The flow rate inside the infusion tube 32 will also increase as the angle of the rotating arm 11 increases, thus perfectly adapting to people of all ages.

[0030] Example 2: Refer to Figures 1-5 Similar to Example 1, but with a further improvement: a threaded rod 2 is threadedly connected to the support rod 1. The threaded rod 2 is hollow and rotatably connected to the lifting support rod 3. A sealing ring 22 is fixedly connected to the threaded rod 2. A rotating plug 23 is rotatably connected to the threaded rod 2 and communicates with the infusion tube 32. A threaded cap 211 is rotatably connected to the threaded rod 2. A puncture diaphragm 21, made of rubber, is fixedly connected to the threaded cap 21. An eccentric plug 311 is fixedly connected to the end of the connecting rod 31 near the lifting support rod 3. When rotated... When the arm 11 is opened, the pressure of the eccentric block 311 on the infusion tube 32 decreases. When the rotating arm 11 is closed, the pressure of the eccentric block 311 on the infusion tube 32 increases. A sliding block 5 is slidably connected to the rotating arm 11. The sliding block 5 and the rotating arm 11 are interference fit. A guide rod 52 is fixedly connected inside the rotating arm 11. A squeezing block 51 is slidably connected to the guide rod 52. When the squeezing block 51 slides on the guide rod 52, the degree of pressure of the squeezing block 51 on the infusion tube 32 changes. A sliding rod 53 is fixedly connected to the sliding block 5. The sliding rod 53 is slidably connected to the squeezing block 51.

[0031] In this invention, a small threaded cap 211 is threadedly connected to the knob at the top of the threaded rod 2. A puncture diaphragm 21 is fixedly connected above the threaded cap 211. The threaded cap 211 can be replaced by threading. The user can inject liquid into the threaded rod 2 by puncturing the puncture diaphragm 21 with a butterfly needle. The puncture diaphragm 21 can also be replaced with an interface that communicates with a hose and is connected to the hose by an interference fit. The liquid passes through the threaded rod 2 to the rotating plug 23 and enters the infusion tube 32. A sealing ring 22 is fixedly connected to the bottom of the threaded rod 2. By setting the sealing ring 22, the sealing effect between the threaded rod 2 and the rotating plug 23 can be ensured.

[0032] When the threaded rod 2 rotates, it moves up and down with the support rod 1 as the fulcrum. The lifting support rod 3 moves along with the threaded rod 2, thereby driving the connecting rod 31 to move. When the connecting rod 31 moves with the lifting support rod 3, it drives the rotating arm 11 to open or close. When the connecting rod 31 rotates, it will drive the eccentric block 311 to squeeze the infusion tube 32. The larger the angle of the rotating arm 11 opening, the smaller the squeeze of the eccentric block 311 on the infusion tube 32, and the greater the flow rate of the infusion tube 32. Conversely, the smaller the angle of the rotating arm 11 opening, the smaller the flow rate of the infusion tube 32.

[0033] Besides adjusting the flow rate of the infusion tube 32 by adjusting the unfolding angle of the rotating arm 11, the internal squeezing block 51 can be moved along the guide rod 52 by sliding the sliding block 5. The sliding block 5 and the rotating arm 11 are interference-fitted. The sliding block 5 drives the squeezing block 51 to slide along the direction of the rotating arm 11 via the sliding rod 53. Figure 4 As shown, when the squeezing block 51 moves to the right, the squeezing degree of the squeezing block 51 on the infusion tube 32 increases, and the flow rate of the infusion tube 32 decreases. When the squeezing block 51 moves to the left, the flow rate of the infusion tube 32 increases.

[0034] When using the device, the user first hooks the patient's eyelid with the eyelid clip 4, then adjusts the opening angle of the rotating arm 11 by rotating the threaded rod 2, thereby opening the patient's eyelid. After opening to a suitable angle, the butterfly needle connected to the infusion bag can be inserted into the puncture diaphragm 21, and the liquid in the infusion bag will automatically flow into the infusion tube 32 and flow out from the water outlet 41 into the patient's eyes to keep the patient's eyes moist. The user can also adjust or close the flow rate by sliding the sliding block 5 according to specific needs.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
