Description

Technical Field

[0001] This utility model relates to the field of ophthalmic medical equipment technology, and in particular to a conjunctival sac drainage device. Background Technology

[0002] During intraocular surgery, an eyelid speculum is used to open the eyelids and expose the eyeball. During the procedure, saline solution needs to be continuously dripped onto the corneal surface to maintain corneal transparency. In some patients, due to a small palpebral fissure or enophthalmos, the opened eyelid margin is higher than the surface of the eyeball. Fluid dripped onto the cornea and any leakage during the procedure can easily accumulate on the surface of the eyeball. If not drained, this will affect the surgeon's vision, potentially leading to surgical errors and failure.

[0003] Currently, fluid accumulation is usually absorbed by medical staff using cotton swabs or gauze, or by slightly tilting the patient's head to allow the fluid to drain. This process needs to be repeated multiple times during surgery, which can interfere with the normal progress of the procedure. Therefore, Chinese utility model patent ZL2023204495845 was developed, disclosing a double-drainage drainage device for ophthalmic surgery. This device includes a negative pressure balloon and a hollow hook communicating with the inside of the balloon. The hollow hook consists of a connecting end communicating with the negative pressure balloon and a hook end. A drainage hole is provided at the end of the hook end, and the drainage hole is connected to the inside of the negative pressure balloon.

[0004] The above-mentioned patent has at least the following problems: First, the inside of the hollow hook and the drainage hole are inconvenient to clean and disinfect, and are not suitable for reuse, which will increase the cost of use; Second, after the accumulated fluid flows out along the outer wall of the hollow hook, it will flow onto the patient's face or the operating table, and medical staff still need to use cotton swabs or gauze to absorb and wipe it, which will affect the normal progress of the operation. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a conjunctival sac drainage device. This invention is not only easy to clean, disinfect, and reuse, but also guides and collects flushing fluid, effectively improving the drainage device's performance.

[0006] The technical solution of this utility model to solve the technical problem is as follows: a conjunctival sac drainage device, including a reservoir ball and a drainage pressure plate. The top of the reservoir ball is provided with a liquid inlet and two sets of hooks. The two sets of hooks are respectively set on both sides of the liquid inlet. The two sides of the drainage pressure plate are respectively connected to the two sets of hooks. The bottom of the drainage pressure plate is connected to the liquid inlet.

[0007] As an optimization, a U-shaped hook is also included, with each end of the U-shaped hook connecting to the bends of two sets of hooks. By setting the U-shaped hook, the two sets of hooks can be connected, improving the stability of the hooks and preventing the bends of the hooks from poking the eyes.

[0008] As an optimization, the two sets of hooks and the U-shaped hook head are molded as a single piece. This improves the stability of the hooks.

[0009] As an optimization, the drainage plate is an arc-shaped plate with a drainage groove on its concave surface and the convex surface facing the side where the U-shaped hook is located. By setting the drainage groove on the concave surface, the flushing fluid can be guided to flow into the reservoir ball, while the convex surface can press down on the skin at the outer corner of the eye, further facilitating the outflow of the flushing fluid.

[0010] As an optimization, the width and depth of the drainage channel gradually decrease from top to bottom. The end of the drainage channel near the outer corner is wider and deeper, which can expand the collection range of the flushing fluid; the end of the drainage channel near the liquid storage ball is narrower and shallower, which can ensure a stable flow of flushing fluid into the inlet.

[0011] As an optimization, the liquid storage sphere includes a first sphere and a second sphere. The liquid inlet is located at the top of the first sphere, and the bottom of the first sphere is detachably connected to the top of the second sphere via threads. By setting up the first and second spheres, disassembly and cleaning / disinfection can be easily facilitated.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting up a reservoir and inlet, a counterweight can be provided for the hook, which can collect and store the irrigation fluid and prevent it from flowing around. By setting up a drainage plate, the skin at the outer canthus can be pressed down, guiding the irrigation fluid from the corner of the eye to flow into the reservoir through the inlet, thus preventing fluid accumulation in the conjunctival sac. By setting up a hook, the outer canthus can be hooked, allowing the drainage plate to naturally press down on the skin at the outer canthus and also assisting in opening the upper and lower eyelids.

[0018] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0019] Example 1

[0020] Figures 1 to 3 As one embodiment of this utility model, such as Figures 1 to 3 As shown, a conjunctival sac drainage device includes a reservoir ball 1 and a drainage pressure plate 2. The top of the reservoir ball 1 is provided with an inlet 3 and two sets of hooks 4. The two sets of hooks 4 are respectively arranged on both sides of the inlet 3. The two sides of the drainage pressure plate 2 are respectively connected to the two sets of hooks 4, and the bottom of the drainage pressure plate 2 is connected to the inlet 3.

[0021] By setting up the reservoir ball 1 and the inlet 3, the hook 4 can be provided with counterweight, which can collect and store the irrigation fluid and prevent it from flowing around. By setting up the drainage pressure plate 2, the skin at the outer canthus can be pressed down, guiding the irrigation fluid from the corner of the eye to flow into the reservoir ball 1 through the inlet 3, thus preventing fluid accumulation in the conjunctival sac. By setting up the hook 4, the outer canthus can be hooked, so that the drainage pressure plate 2 can be naturally pressed down on the skin at the outer canthus, and can also help open the upper and lower eyelids. Both the hook 4 and the drainage pressure plate 2 are easy to clean and disinfect.

[0022] like Figure 1 and Figure 3 As shown, it also includes a U-shaped hook head 5, the two ends of which are connected to the hooks of the two sets of hooks 4 respectively. By setting the U-shaped hook head 5, the two sets of hooks 4 can be connected, improving the stability of the hooks 4 and preventing the hooks of the hooks 4 from poking the eyes.

[0023] The two sets of hooks 4 and the U-shaped hook head 5 are molded as one piece. This can improve the stability of hook 4.

[0024] like Figure 1 and Figure 2 As shown, the drainage pressure plate 2 is an arc-shaped plate. The concave surface of the drainage pressure plate 2 is provided with a drainage groove 6, and the convex surface of the drainage pressure plate 2 faces the side where the U-shaped hook head 5 is located. By providing the drainage groove 6 on the concave surface, the flushing fluid can be guided to flow into the reservoir ball 1. At the same time, the convex surface can also press down on the skin at the outer corner of the eye, further facilitating the outflow of the flushing fluid.

[0025] like Figure 1 and Figure 2 As shown, the width of the drainage channel 6 gradually decreases from top to bottom, and the depth of the drainage channel 6 also gradually decreases from top to bottom. The end of the drainage channel 6 near the outer corner is wide and deep, which can expand the collection range of the flushing fluid; the end of the drainage channel 6 near the liquid storage ball 1 is narrow and shallow, which can guide the flushing fluid to flow steadily into the liquid inlet 3.

[0026] like Figures 1 to 3 As shown, the liquid storage ball 1 includes a first ball 7 and a second ball 8. The liquid inlet 3 is located on the top of the first ball 7, and the bottom of the first ball 7 is detachably connected to the top of the second ball 8 via threads. By providing the first ball 7 and the second ball 8, disassembly and cleaning / disinfection can be easily facilitated.

[0027] In use, the U-shaped hook 5 and the hooks of the two sets of hooks 4 are inserted into the conjunctival sac from the outer canthus. Under the counterweight of the reservoir bulb 1, the convex surface of the drainage plate 2 can press down on the skin of the outer canthus. The two sets of hooks 4 can not only help open the upper and lower eyelids, but also open a channel for the drainage of fluid. When medical staff use saline to rinse the eyeball, the rinsing solution can flow along the pressed outer canthus into the concave surface of the drainage plate 2, and flow to the reservoir bulb 1 through the drainage groove 6. The rinsing solution enters the reservoir bulb 1 through the inlet 3. After the operation, the first bulb 7 and the second bulb 8 can be separated and opened. After the collected rinsing solution is poured out, the whole body can be cleaned and disinfected.
