[0046] The rotating head 127 is rotatably connected to the handle assembly 13;

[0047] The rotating head 127 is also fixedly connected to the flushing tube 121 and the outer sleeve tube 122. The connection structure of the rotating head 127 is a conventional technique, so no further elaboration will be made.

[0048] Embodiment 2:

[0049] As Figures 3 to 5 shown, the tail of the sleeve tube 122 does not extend to the handle assembly 13, so that a bare area that is not covered by the outer sleeve tube 122 is left at the tail of the flushing tube 121, forming a connection area 128 for connecting to the high-frequency device. This connection area 128 is used as a connecting part.

[0050] When encountering a bleeding position, the flushing tube 121 can be connected to the high-frequency device by using the connection area 128 to process the bleeding area.

[0051] It should be noted that the structures of the nozzle assembly 11 and the connecting rod assembly 12 in Embodiment 2 are the same as those in Embodiment 1. The difference is that the conductive pin 135 on the handle assembly 13 is cancelled, and the structure is as described below:

[0052] The handle assembly 13 includes:

[0053] The outer housing 131, which serves as the main body of the handle assembly 13:

[0054] The connecting tube 132, which is arranged inside the outer housing 131. The front end of the connecting tube 132 is connected to the rear end of the flushing tube 121, and the rear end of the connecting tube 132 is connected with a docking head 133 for connecting to an external device; and

[0057] The flushing tube 121 and the connecting tube 132 are connected through the flushing tube joint 125 and the connecting head 136. Among them, the button 134 is arranged on the connecting tube and cooperates with the outer housing 131, and the on-off of the flushing liquid is realized by pressing the button 134.

[0058] The side wall of the flushing tube joint 125 is provided with an annular connecting groove 126;

[0059] The front end of the connecting head 136 is provided with an annular piece 137 that is cooperatively connected with the annular connecting groove 126;

[0060] A sealing ring 138 is also provided at the connection between the annular connection groove 126 and the annular piece 137.
