Description

Technical Field

[0001] This utility model relates to the field of ophthalmic medical equipment technology, and in particular to a medical ophthalmic infusion tubing and equipment. Background Technology

[0002] In ophthalmic surgery, ophthalmic irrigation tubing is widely used to maintain intraocular pressure and provide a clear surgical field, playing a crucial role, especially in procedures such as vitrectomy and retinal surgery. However, while using high-strength materials to construct irrigation tubing ensures stable irrigation pressure during surgery, it also results in high overall tubing rigidity. This rigidity makes the tubing difficult to bend flexibly during surgery, and any bends are prone to springback, increasing the risk of the tubing tip detaching from the ocular irrigation channel. Furthermore, during surgical procedures, sharp bends can cause radial collapse at the bend, potentially leading to tubing blockage and further increasing the surgical risk. Utility Model Content

[0003] The purpose of this utility model is to provide a medical ophthalmic infusion tubing and device to alleviate the technical problems of existing medical ophthalmic infusion tubing being prone to bending and rebounding, and easily collapsing and causing blockage.

[0012] In conjunction with the third possible implementation of the first aspect, this utility model provides a fifth possible implementation of the first aspect, wherein the wall thickness of the second flexible tube is greater than the wall thickness of the first flexible tube.

[0013] In conjunction with the third possible implementation of the first aspect, the present invention provides a sixth possible implementation of the first aspect, wherein the outer diameter of the second flexible tube is larger than the outer diameter of the first flexible tube.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figure 1 , Figure 5 and Figure 6 As shown, the medical ophthalmic infusion tubing provided in this embodiment of the present invention includes: a first flexible tube 100, a first micro-spring 200, and a positioning wire 300; the first micro-spring 200 is installed inside the first flexible tube 100 and supports the first flexible tube 100 radially; the positioning wire 300 extends axially along the first flexible tube 100 and is connected to the first flexible tube 100 and / or the first micro-spring 200.

[0031] The positioning wire 300 connects to the first flexible tube 100 or the first micro-spring 200, or the positioning wire 300 connects between the first flexible tube 100 and the first micro-spring 200. The first micro-spring 200 can be configured as a spiral structure, or it can be a plurality of annular structures spaced apart along the axial direction of the first flexible tube 100. The first micro-spring 200 is supported inside the first flexible tube 100, and the bent part of the first flexible tube 100 can avoid radial collapse under the support of the first micro-spring 200, thereby preventing blockage at the bent part. The positioning wire 300 is made of stainless steel and can maintain its bent state after bending, which can counteract the springback force when the first flexible tube 100 is bent, thereby maintaining the bent state of the pipeline.

[0032] In an optional embodiment, multiple positioning wires 300 are provided, and the multiple positioning wires 300 extend along the axial direction of the first flexible tube 100 and are connected to the first micro spring 200.

[0033] When assembling a medical ophthalmic infusion tubing, multiple positioning wires 300 can be connected to the outside of the first micro-spring 200 by laser welding. The positioning wires 300 and the first micro-spring 200 are then inserted into the first flexible tube 100, and the multiple positioning wires 300 are connected to the first flexible tube 100.

[0034] Furthermore, one end of the first flexible pipe 100 is connected to the pressure relief pipe 400, and the positioning screw 300 is connected to the pressure relief pipe 400. The pressure relief pipe 400 is used to connect to the injection joint, and the positioning screw 300 can be connected to the pressure relief pipe 400 by welding. This improves the strength of the connection between the pressure relief pipe 400 and the first flexible pipe 100, and also allows the connection between the pressure relief pipe 400 and the first flexible pipe 100 to be flexible and maintain its bent shape.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the medical ophthalmic irrigation tubing includes: a second flexible fitting 500 and an adapter 600; a first flexible fitting 100 is sleeved on one end of the adapter 600, and a second flexible fitting 500 is sleeved on the other end of the adapter 600.

[0036] The first flexible tube 100 and the second flexible tube 500 can be made of elastic and bendable materials such as silicone or rubber. The two ends of the adapter 600 are respectively equipped with conical plugs. One conical plug is inserted into the first flexible tube 100 and the other conical plug is inserted into the second flexible tube 500, so that the first flexible tube 100 and the second flexible tube 500 are connected through the adapter 600.

[0037] In an optional embodiment, the hardness of the second flexible tube 500 is greater than that of the first flexible tube 100. The second flexible tube 500 can be used to connect to the injection pressure source, and the second flexible tube 500 has greater hardness to make the pipeline connected to the injection pressure source more stable. The first flexible tube 100 has lower hardness and is easier to bend, which facilitates bending operations during surgery.

[0038] In an optional embodiment, the wall thickness of the second flexible tube 500 is greater than that of the first flexible tube 100, which can increase the rigidity of the second flexible tube 500. In other words, the wall thickness of the first flexible tube 100 is smaller and it is easier to bend.

[0039] In an optional embodiment, the outer diameter of the second flexible tube 500 is larger than the outer diameter of the first flexible tube 100.

[0040] In an optional embodiment, a second micro-spring 700 is installed inside the second flexible tube 500. The second micro-spring 700 supports the second flexible tube 500 radially and can prevent the second flexible tube 500 from collapsing radially when it is bent, thus preventing blockage at the bending part of the second flexible tube 500.

[0041] In addition, the adapter 600 can be made of metal or polymer material into an integral structure. The first micro spring 200 and the second micro spring 700 can be welded to the adapter 600 respectively, or the first micro spring 200 and the second micro spring 700 can be formed into an integral structure with the adapter 600 by injection molding.

[0042] The medical ophthalmic infusion device provided in this embodiment of the present invention is equipped with the medical ophthalmic infusion tubing described in the above embodiments.

[0043] In this embodiment of the invention, the medical ophthalmic irrigation device delivers fluid media through the aforementioned irrigation tubing, making it suitable for irrigation operations in ophthalmic medicine. The tubing's flexibility and stability after bending, without springback, improves the convenience of surgical procedures and reduces the risk of tubing connections becoming loose due to springback. Furthermore, it provides radial support to the tubing, preventing radial collapse at bends and effectively preventing blockages. This ensures a smooth ophthalmic irrigation process, making it particularly suitable for ophthalmic irrigation surgeries that maintain intraocular pressure and provide a clear surgical field.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
