[0028] Example: Application in laparoscopic surgery in urology

[0029] During laparoscopic surgery in urology, when clamping is required, the control handle 4 and the control rod 3 are used to operate the clamp 2 to clamp the patient's foreign body or stone; when the patient's body needs to be flushed, the clamp 2 is no longer operated to clamp, and the three-way valve 8 is rotated to the state where the guide tube 7 and the flushing connecting tube 10 are connected by rotating the wheel 14, and the flushing liquid supply device outside the flushing connecting tube 10 is started. The control handle 4 is operated to control the position of the through hole 6 on the drainage flushing part 5 to flush the required position, or the clamp 2 is clamped in the working state, and the index finger on the same side rotates the three-way valve 8 to the state where the guide tube 7 and the flushing connecting tube 10 are connected by rotating the wheel 14 during the operation to perform the flushing work; when the patient's body needs to be sucked out of the liquid, the clamp 2 is no longer operated to clamp, and the wheel 1 is used to rotate the three-way valve 8 4 rotates the three-way valve 8 to the state where the guide tube 7 and the drainage connecting tube 9 are in communication, and the negative pressure drainage device outside the drainage connecting tube 9 is started. The control handle 4 is operated to control the position of the through hole 6 on the drainage flushing member 5 to aspirate the liquid, or the three-way valve 8 is rotated to the state where the guide tube 7 and the drainage connecting tube 9 are in communication while the clamp 2 is clamped in the working state, and the index finger is used to rotate the wheel 14 to perform drainage. When the clamp 2 is clamped in the working state and no flushing or aspiration is required, the index finger on the same side can be used to rotate the wheel 14 to rotate the three-way valve 8 to the neutral "closed" state, and the flushing and aspiration functions are stopped. Through the above steps, when clamping and fixing the target tissue or stone, aspiration and flushing can be completed at the same time without changing the instruments with independent functions of grasping, aspiration, and flushing.
