[0026] Please refer to Figures 1-3 The present application provides a technical solution of an anti-clogging auxiliary flushing and suction device: comprising a sheath tube 1, the bottom end of the sheath tube 1 is provided with a suction hole 7, the top end of the sheath tube 1 is provided with a suction connection end 3, the inside of the sheath tube 1 is provided with a suction cavity 11, the suction hole 7 and the suction connection end 3 are communicated through the suction cavity 11;

[0027] A flushing chamber 13 is provided on the side wall of the sheath tube 1. A flushing connection end 2 is installed on one side of the top end of the sheath tube 1. A flushing hole 6 is provided on one side of the bottom end of the sheath tube 1. The flushing connection end 2 and the flushing hole 6 are connected through the flushing chamber 13.

[0028] Connecting rods 8 are slidably connected to both sides of the bottom end of sheath 1, and elastic supports 5 are fixedly connected to both sides of the bottom end of sheath 1. A connecting crossbar 12 is fixedly connected inside the suction cavity 11, and an arc-shaped support 9 is fixedly connected to the bottom end of the connecting crossbar 12. A pin 10 is fixedly connected to the bottom end of the arc-shaped support 9. The two ends of the connecting rod 8 are fixedly connected to the elastic support 5 and the arc-shaped support 9, respectively. The diameter of the pin 10 is smaller than the inner diameter of the suction hole 7. The pin 10 is located directly above the suction hole 7. The elastic support 5 is trapezoidal in shape, and there are two arc-shaped supports 9. The two arc-shaped supports 9 are symmetrically distributed. Under normal conditions, the two arc-shaped supports 9 are O-shaped. When the middle of the two sides of the two arc-shaped supports 9 is squeezed, the two arc-shaped supports 9 deform, thereby driving the pin 10 at its bottom end to move downward, thereby pushing out the blockage in the suction hole 7.

[0029] The surface of the sheath 1 is provided with anti-slip texture 4, which is located above the elastic support 5, making it convenient to use the surgical robot to clamp the sheath 1 and avoid slipping during clamping.

[0030] In practical use, when the suction hole becomes blocked, the robotic gripper presses the elastic supports 5 on both sides of the bottom end of the sheath 1 inward. At this time, the elastic supports 5 drive the middle part of the arc-shaped support 9 to bend inward through the connecting rod 8, so that the arc-shaped support 9 can drive the ejector pin 10 at its bottom end to push out of the suction hole 7, thereby pushing out the blockage in the suction hole 7 and keeping the suction hole 7 unobstructed. Compared with the existing flushing suction device, this utility model can easily push out the blockage in the suction hole 7 without the need for manual cleaning with other instruments. The suction hole cleaning is more efficient, does not affect the surgical process, and is more convenient to use.

[0031] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations made to these embodiments within the spirit and principles of this utility model, through conventional substitutions or methods that achieve the same function without departing from the principles and spirit of this utility model, fall within the scope of protection of this utility model.
