[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] The utility model provides a knee joint flushing device, which facilitates the positioning of the flushing component through the provided guide needle, and facilitates the introduction and discharge of liquid medicine during flushing through the provided three-way pipe. Compared with the existing method of switching between liquid inlet and liquid discharge back and forth through one port, the utility model has the advantage of high cleaning efficiency.

[0026] Figure 1-Figure 3 The structure diagram of an embodiment of a knee joint washing device of the present invention is shown in FIG. Figure 1-Figure 3 In this embodiment, a knee joint flushing device has a main body including a guide component 100 and a flushing component 200.

[0027] The guide assembly 100 includes a guide needle 110 and a handle 120 disposed at the rear end of the guide needle 110. Preferably, in this embodiment, the outer wall of the guide needle 110 close to the handle 120 is provided with a first external thread 111, and the inner middle part of the handle 120 is provided with a threaded hole 121, and the guide needle 110 is threadedly connected with the handle 120. The guide needle 110 is threadedly mounted on the handle 120 under the action of the first external thread 111 and the threaded hole 121, and the operator can manually rotate the two to separate them in the later stage so as to disassemble and replace them.

[0028] The flushing assembly 200 includes a three-way tube 210 sleeved on the outside of the guide needle 110 and a sleeve 220 arranged at one end of the three-way tube 210. The sleeve 220 is connected to the three-way tube 210, and the sleeve 220 is in contact with the inner wall of the three-way tube 210 and the outer wall of the guide needle 110. Preferably, in this embodiment, the inner wall of the three-way tube 210 is provided with an internal thread 211 near the end of the sleeve 220, and the outer wall of the sleeve 220 is provided with a second external thread 221 near the end of the three-way tube 210. The sleeve 220 is threadedly connected to the three-way tube 210, and the sleeve 220 is threadedly installed on the three-way tube 210 under the action of the second external thread 221 and the internal thread 211, so that the operator can disassemble and assemble it later for inspection and replacement. The outer wall of the sleeve 220 away from the end of the three-way tube 210 is chamfered, and the sleeve 220 with the chamfered outer wall can prevent the sleeve 220 from being damaged. 0's end may injure skin tissue, thereby enhancing the safety of the device. The inner wall of the sleeve 220 near the end of the tee 210 is chamfered. The sleeve 220 with the chamfered inner wall can drain the liquid medicine when injecting it to prevent the liquid medicine from remaining at the end of the sleeve 220 where the inner wall is not chamfered. A sealing ring is arranged on the outer side of the end of the sleeve 220 near the tee 210. The sealing ring is made of rubber. The sealing ring arranged at the end of the sleeve 220 seals the connection gap between the sleeve 220 and the tee 210 to prevent the liquid medicine from flowing out of the gap, thereby enhancing the sealing of the device.

[0029] Combination Figure 1-Figure 3 , a knee joint flushing device of the present embodiment is specifically used as follows: the operator installs pipes with regulating valves on the two pipe openings of the three-way pipe, then holds the handle 120 to insert the guide needle 110 to the specified position, and then pulls up the handle 120 to remove the guide needle 110 from the sleeve 220 and the three-way pipe 210, and then selects one of the other two pipe openings of the three-way pipe 210 except the insertion end as the liquid inlet and the other as the liquid outlet according to actual usage, and injects the medicine from the liquid inlet. At this time, the regulating valve on the liquid outlet pipe is closed. When a certain amount of medicine is injected, the regulating valve on the liquid inlet is closed, and the medicine soaks the joint cavity. After a certain period of time, the regulating valve on the liquid outlet pipe is opened to discharge the soaked medicine waste. Compared with the existing method of switching the liquid inlet and discharge back and forth through one port, the utility model has the advantage of high cleaning efficiency.

[0030] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
