Further, the diameter of the guide through pipe is smaller than the radius of the guide sleeve, one end of the guide through pipe is communicated with the end face of the guide sleeve, the outer wall of the other end of the guide through pipe is provided with a corrugated connection structure which is used for being matched and connected with the plastic hose, and the corrugated connection structure improves the connection stability of the guide joint and the plastic hose.
Furthermore, the tail end of the guide groove is of a semicircular structure, and a semicircular groove matched with the semicircular structure is arranged in the guide sleeve. The semicircular groove structure is convenient for accessing the guide sleeve, and can improve the connection stability and the tightness of the guide groove and the guide sleeve to a certain extent.
In order to enable the connection surface of the sheath connecting pipe and the rotating sleeve to be smooth, a shaft shoulder is arranged at the tail end of the sheath connecting pipe, the rotating sleeve is sleeved at the tail end of the Guan Qiao connecting pipe and positioned through the shaft shoulder, and the outer diameter of the sheath connecting pipe is identical to that of the rotating sleeve.
In order to facilitate the disassembly and assembly of the sheath connecting pipe and the ureter sheath, the outer wall of the front end of the sheath connecting pipe is provided with a plum blossom ear-shaped structure.
The invention has the advantages and effects that:
1. In the device, the sheath connecting pipe and the water outlet joint handle are arranged in a structure capable of rotating relatively, so that the problem of sheath releasing position change caused by adjusting the angle of the water outlet joint handle can be avoided.
2. The rotary sleeve of the water outlet connector handle is sleeved at the tail end of the Guan Qiao connecting pipe, and the connecting surface is provided with an annular sealing ring, so that the liquid leakage at the connecting position can be avoided while the rotary connection is ensured.
3. The water outlet connector handle is provided with the guide groove, and the guide groove is combined with the guide connector to effectively guide fluid, so that the pollution caused by the influence of the fluid flowing to an operating table is avoided.
