The three-way joint 36 can realize the diversion function of the solution in the cavity to meet different surgical needs; in addition, the cavity can reduce the flow resistance of the solution in the three-way joint 36, so that the solution can flow more smoothly through the three-way joint 36 into the second pipe 34 and the third pipe 35.

[0047] In one embodiment, please refer to Figures 2 to 5As shown, the three-way connector 36 also includes a fourth interface (not shown) communicating with the cavity. The flushing assembly 3 also includes a valve body 37, which includes a valve core 371 adapted to the cavity. The valve core 371 is rotatably inserted into the cavity through the fourth interface. The valve core 371 is used to control the opening or closing of the first interface 362, the second interface 363, and the third interface 364. In this embodiment, the specific shape of the valve core 371 is not limited. The valve core 371 can be box-shaped, cylindrical, spherical, or other shapes. Preferably, the valve core 371 is cylindrical.

[0048] Furthermore, the angle between the axis of the first interface 362 and the axis of the second interface 363 is 90°, the angle between the axis of the second interface 363 and the axis of the third interface 364 is 90°, and the angle between the axis of the third interface 364 and the axis of the first interface 362 is 180°. The valve core 371 includes a first channel 3711, a second channel 3712, a third channel 3713, and a blocking wall (not shown) arranged in a clockwise direction.

At this time, the first pipe 33, the second pipe 34, and the third pipe 35 are interconnected, and the liquid in the first pipe 33 can be simultaneously transported to the second pipe 34 and the third pipe 35.

[0050] When the valve core 371 is rotated 90° in the first direction so that the valve core 371 is rotated from the first position to the second position, after the valve core 371 is rotated to the second position, the first interface 362 and the second channel 3712 are arranged opposite to each other and are connected to each other, the second interface 363 and the third channel 3713 are arranged opposite to each other and are connected to each other, and the blocking wall is arranged opposite to the third interface 364 and blocks the third interface 364. At this time, the first pipeline 33 is connected to the second pipeline 34, the third interface 364 and the third pipeline 35 are blocked, and the liquid in the first pipeline 33 can only be transported to the second pipeline 34.

[0051] When the valve core 371 is in the second position, the valve core 371 is further rotated 90° along the first direction to rotate the valve core 371 from the second position to the third position. After the valve core 371 is rotated to the third position, the first interface 362 and the third channel 3713 are arranged opposite to each other and are connected to each other, the blocking wall is arranged opposite to the second interface 363 and blocks the second interface 363, and the third interface 364 and the first channel 3711 are arranged opposite to each other and are connected to each other. At this time, the first pipeline 33 is connected to the third pipeline 35, the second interface 363 and the second pipeline 34 are blocked, and the liquid in the first pipeline 33 can only be transported to the third pipeline 35.

[0052] When the valve core 371 is in the third position, the valve core 371 is further rotated 90° along the first direction to rotate the valve core 371 from the third position to the fourth position. After the valve core 371 rotates to the fourth position, the blocking wall is arranged opposite to the first interface 362 and blocks the first interface 362. The liquid in the first pipe 33 can only be transported to the first interface 362, and cannot be transported to the cavity, the second pipe 34 and the third pipe 35.

[0053] In this embodiment, the first direction may be clockwise or counterclockwise.
