[0001] The utility model relates to the technical field of medical devices, in particular to an auxiliary device for ophthalmology. Background Art
[0002] Before eye surgery, cutting the patient's eyelashes is a necessary preoperative treatment to avoid affecting the surgical operation. The commonly used method in clinical practice is for the nurse to hold a cotton swab in one hand, press it against the eyelid and turn it outward to fix the eyelid, and in the other hand, hold a micro scissors to cut the patient's eyelashes.
[0003] However, in this method of fixing the eyelids with a cotton swab, when the eyelashes are cut, the cotton swab is prone to slip when it touches the skin, and the effect of fixing the eyelids to evert is weakened, which increases the difficulty of operation for the staff and is easy to cut the skin, causing pain and risk of infection to the patient. At the same time, the cut eyelashes are very easy to fall into the eyes. The broken eyelashes entering the eyes will cause discomfort to the patient's eyes, and in severe cases may further lead to eye infection in the patient.
[0004] Therefore, it is necessary to provide a new ophthalmic auxiliary device to solve the above technical problems. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0022] See also Figures 1 to 4 An embodiment of the utility model provides an ophthalmic auxiliary device, which includes a gripping rod 1.
[0023] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The interior of the holding rod 1 is a hollow structure, one end of the holding rod 1 is provided with an auxiliary head 2 connected to the interior of the holding rod 1, the other end of the holding rod 1 is provided with a negative pressure hose 3 connected to the interior of the holding rod 1, the auxiliary head 2 is a trapezoidal structure, and a number of evenly distributed rubber balls 21 are provided on the upper and lower sides of the outer wall of the auxiliary head 2, the interior of the auxiliary head 2 is a hollow structure, and air inlets 22 are opened on the front and back sides of the outer wall of the auxiliary head 2.
[0024] It should be noted that: by arranging the auxiliary head 2 at the end of the holding rod 1, and arranging the rubber ball 21 and the air inlet 22 on the outer wall of the auxiliary head 2, the staff can hold the holding rod 1 so that the outer wall of the rubber ball 21 is against the patient's eyelid to position the patient's eyelid. At this time, the patient can use the micro scissors to cut the patient's eyelashes. In this process, due to the negative pressure of the external negative pressure device, the cut eyelashes can be sucked into the device through the air inlet 22, thereby preventing the broken eyelashes from entering the eyes, ensuring the safety of the patient's eyes.
[0025] By arranging a plurality of evenly distributed rubber balls 21 on the outer wall of the auxiliary head 2, when controlling the position between the auxiliary head 2 and the patient's eyelid, the rubber balls 21 can increase the friction between the auxiliary head 2 and the patient's eyelid when in contact with the patient's eyelid, so that the auxiliary head 2 can more smoothly lift the patient's eyelid. At the same time, since the rubber balls 21 are elastic, the discomfort of the patient's eyelid when lifting the patient's eyelid can also be reduced.
[0026] By setting the auxiliary head 2 as a trapezoidal structure, since the outer wall of the trapezoidal structure has multiple surfaces and the two adjacent side surfaces are cross-distributed, when the rubber ball 21 is in contact with the patient's eyelids during later use, the air inlet 22 on the outer wall of the auxiliary head 2 will be parallel to the patient's face, and then when the eyelashes are cut later, the two air inlets 22 distributed above and below can smoothly absorb the cut eyelashes.
[0027] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A connecting groove 11 is provided at one end of the holding rod 1 near the auxiliary head 2, and an adapter 12 is provided on the side of the holding rod 1 away from the auxiliary head 2. A connecting adapter tube 31 is provided at the end of the negative pressure hose 3 near the holding rod 1. The adapter tube 31 is sleeved on the outside of the adapter 12, and the end of the negative pressure hose 3 away from the adapter tube 31 is connected to the external negative pressure device. A connecting block 23 connected to the auxiliary head 2 outside the holding rod 1 is provided at the end with a larger side wall area. The interior of the connecting block 23 is connected to the interior of the auxiliary head 2, and the outside of the connecting block 23 is threadedly connected to the interior of the connecting groove 11.
[0028] It should be noted that: by respectively providing the connection groove 11 and the adapter 12 at both ends of the gripping rod 1, in the later use process, the gripping rod 1 and the auxiliary head 2 can be smoothly installed or removed through the connection between the connection groove 11 and the connection block 23, and by screwing the thread, after completing the treatment of a patient, it is also convenient for the staff to screw and remove the auxiliary head 2 after use, replace it, and centrally process the replaced auxiliary head 2, so that the staff can centrally clean and disinfect it smoothly later, and replacing the new auxiliary head 2 can also avoid the phenomenon of cross-infection of the patient's eyes caused by cross-use of the same tool;
[0029] By connecting the adapter tube 31 to the adapter 12, when the device is used, the adapter tube 31 can be directly pulled off the outer wall of the adapter 12 to separate the adapter tube 31 from the adapter 12, so that the staff can clean the eyelashes remaining inside the gripping rod 1 at a later time.
[0030] The adapter tube 31 is made of rubber material, and the inner wall specifications of the adapter tube 31 are smaller than the outer wall specifications of the adapter 12. Therefore, when the two are connected later, the connection between the adapter tube 31 inserted outside the adapter 12 and the adapter 12 can be made more stable, reducing the probability of the two falling off randomly during use.
[0031] The working principle of the ophthalmic auxiliary device provided by the utility model is as follows:
[0032] When using the device later, the negative pressure hose 3 of the device can be connected to the external negative pressure device, and the external negative pressure device can be turned on to work. Then, the staff can hold the gripping rod 1 with one hand and pick up the micro scissors needed with the other hand according to the use habits of their own dominant hand;
[0033] Then the holding rod 1 can be controlled to move until the rubber ball 21 on the outer wall of the auxiliary head 2 at the end of the holding rod 1 is against the patient's eyelids, so that the patient's eyelids can be lifted and fixed. After the patient's eyelids are fixed, the micro scissors can be controlled to cut the patient's eyelashes. In this process, the suction force generated by the external negative pressure device can smoothly suck the cut eyelashes into the device through the negative pressure hose 3, the holding rod 1 and the air inlet 22 opened in the auxiliary head 2, and the use of the device can be completed at this point.
[0034] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
[0035] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
