Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and more specifically to an ophthalmic surgical drain. Background Art
[0002] In traditional ophthalmic surgery, only a lid speculum is used to hold the upper and lower eyelids open. During ophthalmic surgery, especially cataract surgery, water must be frequently flushed into the cornea to prevent it from drying out. Some people have deep eye sockets, so water cannot drain smoothly along the temporal palpebral fissure and accumulates on the surface of the eyeball. The reflective effect of the water can seriously affect the surgeon's field of vision. Existing ophthalmic surgical drainage devices are rare, and most are not suitable. They are cumbersome to operate, ineffective, and cause great pain to patients. These problems directly affect the success rate of the surgery and the patient's recovery speed. Therefore, there is an urgent need for a new ophthalmic drainage device with a reasonable design, easy use, and good drainage effect to address the shortcomings of the existing technology. Summary of the Invention
[0003] The purpose of the utility model is to solve the deficiencies of the prior art and to provide an ophthalmic surgical drain that is stable and reliable and improves the efficiency and safety of ocular surface fluid drainage.
[0004] The utility model adopts the following technical solutions to achieve the above-mentioned purpose: an ophthalmic surgical drainage device, characterized in that it includes a drainage funnel and a heavy hammer, and a drainage arc surface corresponding to the corneal segment is provided at the upper end of the drainage funnel to achieve the effect of fitting the conjunctiva; hooks are provided on both sides of the drainage funnel, and the drainage effect is achieved by hanging and pulling open the eyelids at the outer canthus; the drainage funnel is provided with a left adjustment plate and a right adjustment plate, and the left adjustment plate and the right adjustment plate are arranged below the drainage arc surface, and the left adjustment plate and the right adjustment plate are connected with an opening and closing control component for adjusting the degree of opening.
[0005] As a further illustration of the above solution, the edge of the drainage arc surface is slightly bent inwards, the purpose of which is to better contact the conjunctiva and prevent water leakage.
[0006] Furthermore, the opening and closing control component is a knob control device, which includes a knob and a screw. The knob and the screw are engaged for transmission. The left adjustment plate and the right adjustment plate are respectively provided with a winding wire wound around the screw, and the degree of opening can be adjusted by the knob.
[0007] Furthermore, a drainage tube is connected to the bottom of the drainage funnel to achieve a good drainage effect.
[0008] Furthermore, there are two weights, which are arranged on both sides of the drainage funnel.
[0009] Furthermore, the weight is a solid teardrop-shaped structure for increasing gravity.
[0010] The beneficial effects that can be achieved by the above technical solutions of the present invention are:
[0011] The utility model adopts an ophthalmic surgical drainage structure mainly composed of a drainage funnel and a heavy hammer. A drainage arc surface corresponding to the corneal segment is provided at the upper end of the drainage funnel to achieve the effect of fitting the conjunctiva. Through the drainage device itself closely fitting the conjunctiva and the pulling effect of its own gravity, it can play a good drainage effect during surgery. In addition, the outer canthus can adjust the opening angle of the drainage device through a knob to better adapt to palpebral fissures of different opening degrees, better adapt to the needs of ophthalmic surgery, reduce the patient's pain, improve the surgical effect and postoperative recovery speed, and is easy to operate, highly practical, and highly convertible.

The following description of the embodiments with reference to the accompanying drawings is illustrative and intended to explain the present invention, but should not be construed as limiting the present invention.
[0019] like Figure 1 As shown, the utility model is an ophthalmic surgical drainage device, comprising a drainage funnel 1 and a weight 2. In this embodiment, there are two weights, which are arranged on both sides of the drainage funnel to play a good balancing role. The weight 2 is a solid teardrop-shaped structure, which is used to increase gravity. A drainage arc surface 1-1 corresponding to the corneal segment is provided at the upper end of the drainage funnel 1 to achieve the effect of fitting the conjunctiva. The position of the drainage arc surface is equivalent to the part where the eyelid is separated by the eyelid speculum, which is slightly smaller than the eyelid speculum; the edge of the drainage arc surface is slightly bent inward, the purpose of which is to better contact the conjunctiva and prevent water leakage. Hooks 1-2 are provided on both sides of the drainage funnel, respectively, to achieve the drainage effect by hanging and pulling open the eyelid at the outer canthus. The bottom of the drainage funnel is connected to a drainage tube 3 to achieve a good drainage effect.
[0020] The drainage funnel is provided with a left adjustment piece 1-3 and a right adjustment piece 1-4, which are arranged below the drainage arc surface. The left and right adjustment pieces are connected to an opening and closing control component 1-5 for adjusting the degree of opening. In this embodiment, the opening and closing control component is a knob control device, which includes a knob and a screw. The knob and the screw are meshed and driven. The left and right adjustment pieces are respectively provided with a winding wire wrapped around the screw. The degree of opening can be adjusted by turning the knob. The angle of opening of the drainage device can be adjusted by turning the knob at the outer canthus to better accommodate different degrees of eyelid opening.
[0021] Compared with existing technologies, the drain device used in this utility model can be hung directly on the temporal palpebral fissure, making it easy and quick to operate. It has three unique features: First, the drain device can be adjusted in width to accommodate different palpebral fissure widths at the lateral canthus; second, the upper portion of the drain device (closer to the cornea) is curved, better fitting the conjunctiva, allowing water to flow along the drain device without leakage; and third, a solid gravity portion at the bottom, pulled downward by gravity, smooths the palpebral fissure at the lateral canthus and facilitates drainage. Through its optimized structural design, this drain device can better meet the needs of ophthalmic surgery, reduce patient pain, and improve surgical results and postoperative recovery. It is easy to operate, highly practical, and has high transferability.
[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
