Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an ophthalmic surgical box. Background Technology

[0002] Ophthalmic surgery is a crucial method for treating eye diseases, with cataract surgery and vitrectomy targeting the anterior and posterior segments of the eye, respectively. Maintaining intraocular pressure balance is essential during both procedures, achieved through irrigation and aspiration of fluids. Ophthalmic surgical kits, as key surgical consumables, are equipped with specialized irrigation and aspiration tubing systems to deliver sterile fluids into the eye and remove any contaminated fluids generated during surgery.

[0003] Currently, ophthalmic surgical kits used in clinical practice mainly adopt an integrated design, with the kit body and tubing bonded together as a single structure using adhesive or welding processes. The tubing is mostly made of medical-grade silicone. While this design ensures a tight seal, it results in high overall manufacturing costs and complex production processes. To balance reusability and cost control, some surgical kits employ Luer connectors, allowing for the replacement of some tubing components after a single surgery. This approach is suitable for routine single-segment surgeries, but in combined anterior and posterior segment surgeries, where multiple irrigation / aspiration tubing lines need to be connected simultaneously, the existing Luer connectors lack variety and differentiation, easily leading to tubing misalignment during surgery. This not only affects surgical efficiency but may also cause serious risks of cross-infection. Utility Model Content

[0062] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0063] like Figure 1 , Figure 2 , Figure 3 As shown, the ophthalmic surgical box provided in this embodiment includes: a box body 100, a top cover 200, and a connector 300; the box body 100 has a cavity inside and a connecting part 110 communicating with the cavity, which is used to store the infusion fluid entering the eye and the fluid aspirated from the eye for management; the connecting part 110 is used to connect the connector 300, which is connected to an external pipeline for infusion and aspiration of fluid.

[0064] The top cover 200 is placed on the box body 100. The box body 100 and the top cover 200 are usually made of plastic and can be assembled into a whole by ultrasonic welding, hot plate welding, bonding and other processes. The top cover 200 is provided with a through hole 210 for the connector 300 to pass through, so that the connector 300 can pass through the through hole 210 and connect to the connecting part 110.

[0065] The outer surface of the connector 300 is recessed to form a connecting groove, which includes a vertical groove 310 and an inclined spiral groove 320 that are interconnected. The wall of the through hole 210 is provided with an inner boss 220. The inner boss 220 has a conical surface 221. The number of inner bosses 220 can be one or more. The inner bosses 220 can move in the vertical groove 310 and the spiral groove 320 to assemble the connector 300 onto the upper cover 200 and communicate with the connecting part 110. Furthermore, the connecting part 110, the through hole 210 and the connecting groove are all provided with multiple corresponding parts. The size of each inner boss 220 is adapted to the size of the corresponding vertical groove 310. Each inner boss 220 is obliquely conical, and the taper of the inner boss 220 is adapted to the corresponding spiral groove 320.

[0066] Specifically, the vertical groove 310 matches the inner boss 220. Different dimensions of the vertical groove 310 and the inner boss 220, such as width or circumference, can produce a one-to-one matching effect. This can achieve a physical foolproof function for the matching between different connectors 300 and the top cover 200, ensuring that each connector 300 can only enter one perforation 210 in the top cover 200, thereby avoiding incorrect pipe connection when connecting pipes. The spiral groove 320 matches the conical surface 221 of the inner boss 220. The conical surface 221 of the inner boss 220 has a different taper. This can provide a physical foolproof function. At the same time, the rotation angle of the spiral groove 320 matches the conical surface 221 of the inner boss 220. The rotational fit produces a locking function similar to thread locking. The length or curvature of the spiral groove 320 is usually shorter than that of a thread, but the spiral angle is larger. This can achieve the locking function when the connector 300 rotates by one-quarter to one-half of the angle.

[0067] The ophthalmic surgical box provided in this embodiment has a connecting part 110 on the box body 100 that communicates with the cavity of the box body 100. The connector 300 passes through the perforation 210 on the upper cover 200 and is connected to the connecting part 110. The outer surface of the connector 300 has an interconnected vertical groove 310 and a rotary groove 320. The hole wall of the perforation 210 is correspondingly provided with an inner boss 220, which can move in the vertical groove 310 and the rotary groove 320. The connector 300 can be connected by screwing on the connector 300. The installation and disassembly of the connector 300 are facilitated, and the dimensions of each inner boss 220 are adapted to the corresponding vertical groove 310. The inner boss 220 and the vertical groove 310 have a one-to-one matching effect, realizing the physical foolproof function. The taper of each inner boss 220 is adapted to the corresponding inclined spiral groove 320, and they rotate and cooperate with each other to further realize physical foolproof, ensuring the uniqueness of the connector 300 installation, and alleviating the technical problems of cumbersome disassembly and assembly and insufficient differentiation of the connector 300 in the prior art.

[0068] Based on the above embodiments, in optional implementations, such as Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the perforation 210 in the ophthalmic surgical box provided in this embodiment has a groove 230 recessed along the diameter direction; the outer surface of the connector 300 is provided with an outer boss 330, which can pass through the groove 230. The width and depth of the groove 230 in different perforations 210 can be the same or different.

[0069] The perforation 210 is usually round, but it can also be rectangular, oval or other irregular shapes. The shape of the perforation 210 is adapted to the shape of the connector 300.

[0070] In addition, hooks can be provided on the box body 100 for hanging waste liquid bags.

[0071] In alternative implementations, such as Figure 11 , Figure 12 , Figure 13 , Figure 14 As shown, the box body 100 is provided with a ramp 120 on the outside of the connecting part 110, and the ramp 120 has a fixed ramp 121; the outer boss 330 has a boss ramp 331, and the boss ramp 331 can abut and cooperate with the fixed ramp 121 so that the outer boss 330 can rotate and move along the fixed ramp 121.

[0072] Specifically, the outer boss 330 of the connector 300 matches the inclined platform 120 of the box body 100. The inclined platform 120 has a fixed inclined surface 121. When the connector 300 enters the through hole 210 of the upper cover 200, the boss inclined surface 331 of the outer boss 330 and the fixed inclined surface 121 cooperate with each other to form an angle or a spiral angle, producing a thread-like tightening effect, thereby realizing the function of locking the connector 300 and the box body 100.

[0073] In an optional embodiment, the top cover 200 is provided with a color block 240 at the perforation 210. Specifically, the perforation 210 is surrounded by a color block 240, which usually contains different colors. Different colors are produced at the position of the color block 240 through processes such as screen printing, pad printing, hot stamping, and pasting.

[0074] In an optional embodiment, the connecting part 110 is configured as a hollow cylinder with a conical surface 221; the outer wall of the hollow cylinder is provided with an outer conical surface 111, or the inner wall of the hollow cylinder is provided with an inner conical surface 112.

[0075] Specifically, the box body 100 has multiple hollow cylinders with conical surfaces 221, including an outer conical surface 111 and an inner conical surface 112. The conical surfaces 221 are typically Luer conical surfaces 221 or non-standard Luer-like conical surfaces 221, such as... Figure 11 As shown, there are 7 hollow cylinders with conical surfaces 221, including an outer conical surface 111 and an inner conical surface 112. The hollow cylinders have inclined platforms 120 around their perimeter. The top of the inclined platform 120 is a fixed inclined surface 121. The inclined surface can be a plane or a spiral surface. Preferably, the inclined surface is a spiral surface.

[0076] In alternative implementations, such as Figure 4 , Figure 15 , Figure 16 As shown, the connector 300 includes an outer cylinder 340, an inner cylinder 350, and an extension tube 360; the outer cylinder 340 covers the inner cylinder 350; the inner wall of the inner cylinder 350 has an inner conical surface 351, and a hollow cylinder extends into the inner cylinder 350. The inner conical surface 351 is used to mate with the outer conical surface 111 of the hollow cylinder. Alternatively, the outer wall of the inner cylinder 350 has an inner conical surface 351, and a hollow cylinder extends into the gap between the inner cylinder 350 and the outer cylinder 340. The hollow cylinder covers the inner cylinder 350, so that the inner conical surface 351 of the outer wall of the inner cylinder 350 mates with the inner conical surface 112 inside the hollow cylinder. The extension tube 360 ​​communicates with the inner cylinder 350, thereby forming a liquid passage between the extension tube 360 ​​and the inner cylinder 350. The extension tube 360 ​​is used to connect with an external pipeline.

[0077] In addition, as another connection method, such as Figure 5 , Figure 17As shown, the connector 300 includes an outer cylinder 340 and an extension tube 360, eliminating the inner cylinder 350; the inner wall of the outer cylinder 340 has an outer cylinder conical surface 341, and a hollow cylinder extends into the outer cylinder 340, with the outer cylinder conical surface 341 mating with the outer conical surface 111; the extension tube 360 ​​communicates with the outer cylinder 340 and is used to connect to external pipelines.

[0078] It is important to note that Figure 17 The diagram shows three connection methods between the connector 300 and the hollow cylinder, from left to right: the left side shows the hollow cylinder fitted onto the inner cylinder 350; the middle side shows the inner cylinder 350 fitted onto the hollow cylinder; and the right side shows the outer sleeve fitted onto the hollow cylinder.

[0079] In an optional embodiment, the outer wall of the extension tube 360 ​​is provided with a barbed structure 361 for connecting with an external pipeline, and the extension tube 360 ​​and the pipeline are assembled together by interference fit or adhesive bonding through the barbed structure 361.

[0080] In an optional embodiment, the connector 300 further includes a wing structure 370; the wing structure 370 is located on the side of the outer cylinder 340 away from the connecting portion 110, and two wing structures 370 are provided, which are symmetrically arranged on both sides of the extension tube 360. The arrangement of the wing structure 370 makes it convenient for the user to tighten the connector 300 by hand.

[0081] In an optional embodiment, a handle 250 is provided on the side of the top cover 200 away from the box body 100 to facilitate picking up and putting down the top cover 200.

[0082] In summary, the ophthalmic surgical box of this embodiment achieves significant technical improvements in the following aspects through its innovative connector 300 design:

[0083] 1. Improved the ease of installation and removal of connector 300;

[0084] 2. Multi-layered physical error-proofing features have been introduced to ensure the correctness and uniqueness of connector 300 installation;
