[0037] See also Figure 1-4 The present invention provides a technical solution for a universal irrigation and suction device for a surgical robot:

[0038] A universal flushing and suction device for a surgical robot comprises: a connecting base 1, one side of which is connected to a catheter 7, and the other side of which is mounted a suction connector 12 and a flushing connector 14, wherein the suction connector 12 is connected to the catheter 7 via a flushing connecting tube 9, and the flushing connector 14 is connected to the catheter 7 via a flushing connecting tube 13;

[0039] The side of the connecting seat 1 is rotatably connected to the suction valve runner 6, the X-direction runner 5, the Y-direction runner 18 and the flushing valve runner 19. The end surfaces of the suction valve runner 6, the X-direction runner 5, the Y-direction runner 18 and the flushing valve runner 19 are all provided with connecting keys;

[0040] A universal adjustment head 8 is installed at the end of the catheter 7. The universal adjustment head 8 includes a Y-axis swing member 21 and an X-axis swing member 22. The Y-axis swing member 21 is hinged to the catheter 7, and the X-axis swing member 22 is hinged to the Y-axis swing member 21.

[0045] The interior of the flushing valve 11 includes a piston rod 1, the end of which is installed with a flushing valve connecting gear rod 16, and the end of the suction valve runner 6 is connected to the flushing valve transmission gear 15, which is meshed with the flushing valve connecting gear rod 16.

[0047] A hose chain is passed between the end of the conduit 7 and the X-axis swing member 22 , and a cavity is provided on the inner wall of the conduit 7 for the X-axis drive rope 20 and the Y-axis drive rope 23 to slide.

[0048] The surfaces of the driving pulley 1 29, the driving pulley 2 31, the transmission pulley 2 27, the transmission pulley 1 25, the X-direction rotating wheel 5 and the Y-direction rotating wheel 18 are all provided with a connecting rope fixing buckle.

[0049] Install the connecting seat 1 on the corresponding part of the surgical robot by a suitable fixing method to ensure a firm connection.

[0050] The suction connector 12 is connected to an external suction device through a corresponding pipeline, and the flushing connector 14 is connected to an external flushing liquid supply device through a pipeline.

[0051] The four motors on the surgical robot are tightly connected to the suction valve rotor 6, the X-direction rotor 5, the Y-direction rotor 18 and the flushing valve rotor 19 through connecting keys.

[0052] When the surgical site needs to be flushed during surgery, the surgical robot controls the flushing valve wheel 19 to rotate, and the flushing valve wheel 19 drives the flushing valve transmission gear 15 to rotate. The flushing valve transmission gear 15 engages with the flushing valve connecting gear rod 16, pushing the piston rod of the flushing valve 11 to move, opening the flushing valve 11, and the flushing fluid is sprayed from the flushing connector 14 through the flushing connecting pipe 13 and the catheter 7, and from the universal adjustment head 8 to flush the surgical site.

[0053] When the surgical site needs to be suctioned, the surgical robot controls the suction valve wheel 6 to rotate, and the suction valve wheel 6 drives the suction valve transmission gear 2 to rotate. The suction valve transmission gear 2 engages with the suction valve connecting gear rod 17, pushing the piston rod 2 of the suction valve 10 to move, opening the suction valve 10, and the flushing fluid and waste in the surgical site are sucked out from the universal adjustment head 8 through the catheter 7 and the flushing connecting pipe 9, and discharged from the suction connecting head 12.

[0054] When the position of the universal adjustment head 8 needs to be adjusted, if swinging in the X-axis direction is required, the surgical robot controls the rotation of the X-direction wheel 5. The X-direction wheel 5 drives the rotation of the drive pulley 2 27 via the X-axis transmission rope 3. The coaxial drive gear 2 26 of the drive pulley 2 27 meshes with the drive gear 3 28, driving the rotation of the drive pulley 1 29. The drive pulley 1 29 pulls the X-axis swing member 22 via the X-axis drive rope 20, achieving the swinging of the universal adjustment head 8 in the X-axis direction. Similarly, if swinging in the Y-axis direction is required, the surgical robot controls the rotation of the Y-direction wheel 18. Through the transmission of the Y-axis transmission rope 4, the drive pulley 1 25, the drive gear 1 24, the drive gear 4 30, the drive pulley 2 31, and the Y-axis drive rope 23, the universal adjustment head 8 is able to swing in the Y-axis direction.

[0055] The working principle of the present invention is as follows: the four motors on the surgical robot are respectively connected to the suction valve rotor 6, the X-direction rotor 5, the Y-direction rotor 18, and the flushing valve rotor 19 via connecting keys. When the position of the universal adjustment head 8 needs to be adjusted, the surgical robot controls the X-direction rotor 5 and the Y-direction rotor 18 to rotate, and through a series of transmission structures, drives the X-axis drive rope 20 and the Y-axis drive rope 23 to move, thereby causing the X-axis swing member 22 and the Y-axis swing member 21 to rotate relative to each other, realizing the swing of the universal adjustment head 8 in the X-axis and Y-axis directions, and accurately positioning the surgical site. When the flushing valve 11 and the suction valve 10 need to be opened or closed, the surgical robot controls the suction valve rotor 6 and the flushing valve rotor 19 to rotate, and through the corresponding gear transmission structure, drives the flushing valve connecting gear rod 16 and the suction valve connecting gear rod 17 to move, realizing the opening and closing of the flushing valve 11 and the suction valve 10, completing the flushing and suction operations.

[0056] The foregoing description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any variation, modification, replacement, integration, or parameter change to these embodiments, which is within the spirit and principles of the present invention and which achieves the same functionality through conventional substitutions, without departing from the principles and spirit of the present invention, falls within the scope of protection of the present invention.
