To address this technical problem, a multifunctional intra-articular irrigation tube is proposed.

[0029] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Example 1

[0031] Please see Figure 1 and 2The present invention provides a structural diagram of a multifunctional intra-articular irrigation tube according to Embodiment 1. The multifunctional intra-articular irrigation tube includes: an outer tube 7, with a drug inlet cavity 2 inside the outer tube 7. An outlet tube is provided at the first end of the drug inlet cavity 2, passing through the first end of the outer tube 7. The second end of the drug inlet cavity 2 passes through the side wall near the second end of the outer tube 7, and a drug inlet port 3 is installed on the second end of the drug inlet cavity 2. An aspiration tube cavity 6 is provided inside the outer tube 7, and an aspiration tube port 5 is also provided on the side wall of the outer tube 7, near the second end of the outer tube 7. The aspiration tube port 5 communicates with the interior of the aspiration tube cavity 6. Several water inlet and drain holes 8 are provided on the side wall near the first end of the outer tube 7, and these water inlet and drain holes 8 communicate with the aspiration tube cavity 6. The aspiration tube cavity 6 is used to transport fluid from the joint cavity to the aspiration tube port 5, thereby draining it from the body or collecting it. The outer tube 7 is used to wrap the internal tubing, protecting it and providing additional stability and support. During irrigation, saline or Ringer's solution can be infused into the patient's joint cavity through the suction cannula port 5.

[0032] In this embodiment, the outer tube 7 is provided with a suction tube cavity 6 so that joint rinsing fluid can be injected into the suction tube cavity 6 through the suction tube port 5, and then enter the patient's joint through the water inlet and drain holes 8. After rinsing is completed, the rinsing fluid is aspirated out through the suction tube port 5. A drug inlet cavity 2 is provided inside the outer tube 7 so that after rinsing the patient, antibiotics or other drugs can be injected through the drug inlet port 3, and then flow into the drug inlet cavity 2 and enter the patient's joint cavity through the outlet tube.

[0033] In a preferred embodiment of this utility model, a plurality of the water inlet and drain holes 8 are evenly distributed on the outer surface of the outer sleeve 7 for water inlet and drainage. The water inlet and drain holes 8 allow the flushing fluid to enter the joint cavity and allow the flushed fluid to flow out of the joint cavity, thus ensuring the smoothness and effectiveness of the flushing process. Six water inlet and drain holes 8 are evenly arranged on the outer surface of the outer sleeve 7.

[0034] Preferably, a plurality of the water inlet and drain holes 8 are evenly distributed on both sides of the outer sleeve 7.

[0035] In a preferred embodiment of the present invention, three, four or five water inlet and drain holes 8 are arranged on both sides of the outer sleeve 7.

[0036] In a preferred embodiment of this utility model, the outer surface of the outer sleeve 7 is provided with a scale line 1. The scale line 1 is provided to facilitate observation of the length inserted into the patient's joint, ensuring that the drainage tube is placed at the correct depth, so as to facilitate effective joint cavity irrigation and drainage.

[0037] In a preferred embodiment of this utility model, the inlet 3 of the drug delivery tube is connected to a syringe or drug delivery system so as to inject the drug into the joint cavity.

[0038] In a preferred embodiment of the present invention, the suction tube port 5 is used to connect to the suction system so as to suction fluid or rinsing fluid from the joint cavity.

[0039] like Figure 2 As shown, in a preferred embodiment of the present invention, the second end of the outer sleeve 7 is further provided with a connecting pipe 4, the inner side of the outer sleeve 7 is provided with an outer sleeve cavity 9, the first end of the outer sleeve cavity 9 is connected to a plurality of water inlet and drain holes 8, and the second end of the outer sleeve cavity 9 is connected to the first end of the connecting pipe 4.

[0040] like Figure 2 As shown, in some embodiments, the inlet tube lumen 2, the aspiration tube lumen 6, and the outer tube lumen 9 are arranged sequentially from the inside to the outside inside the outer tube 7. The inlet tube lumen 2 is not connected to either the aspiration tube lumen 6 or the outer tube lumen 9, which reduces the risk of drainage fluid backflow into the inlet tube lumen and causing difficulties in drug administration. To ensure unobstructed drainage and smooth joint cavity irrigation, the aspiration tube lumen 6 and the outer tube lumen 9 are connected to each other, and these two cavities are closed by the connecting tube 4 at the tail end.

[0041] In a preferred embodiment of this invention, if intra-articular irrigation is required, the connecting tube 4 can also be connected to a negative pressure suction device (most hospital beds are equipped with negative pressure interfaces at the head of the bed). Specifically, the second end of the connecting tube 4 is connected to the connecting pipe of the negative pressure suction device. This is used to drain the injected medication. The inlet 3 and the suction inlet 5 are separate to avoid contamination of the inlet lumen 2 and blockage of it. Connecting to the negative pressure suction device allows for thorough irrigation of the joint cavity, which is beneficial for infection control in PJI patients.

[0042] In a preferred embodiment of this invention, the connecting tube 4 can be connected to a drainage (or flushing) collection device as needed clinically. This collection device is typically a drainage bag with a valve, which is already widely used in clinical practice. Specifically, the second end of the connecting tube 4 is connected to the input end of the drainage bag for recording the drainage volume.

[0043] This invention is used for rinsing, drug delivery, and fluid aspiration within the joint cavity; each component works independently yet collaboratively to improve treatment efficacy, reduce infection risk, and promote patient recovery. In practical use, the tube diameter and orifice design can be optimized; this rinsing tube also helps reduce surgical trauma and accelerate postoperative recovery.
