Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, especially to an endoscope system with perfusion function and convenient control. BACKGROUND

[0002] In the endoscopic surgery when treating kidney stones, continuous perfusion is needed to keep the field of vision clear, but too high perfusion flow rate or poor backflow can cause the intrarenal pressure to rise. When the intrarenal pressure is in a high-pressure state for a long time, bacteria in the renal collecting system can easily flow back into the blood with the liquid, causing infection, so it is crucial to control the intrarenal pressure. Currently, the two important means to control the intrarenal pressure are to adjust the perfusion flow rate or to turn on the negative pressure suction. Therefore, when the renal pelvis pressure is about to exceed the warning line during perfusion, the doctor needs to timely reduce the perfusion flow rate or connect the negative pressure suction and turn on the negative pressure suction to reduce the intrarenal pressure, and when the perfusion flow rate is too low to cause the field of vision to be blurred, the doctor needs to timely increase the perfusion flow rate.

[0003] Currently, the perfusion equipment and the suction equipment of the hospital are separately controlled from the electronic endoscope and the image processor. When the doctor is operating the electronic endoscope, the assistant needs to be ready for instructions at any time, and the doctor needs to inform the assistant to adjust the perfusion equipment or the negative pressure suction equipment at any time. When the assistant is absent or slow to react, information transmission is likely to be delayed, the intrarenal pressure may be in a high state for a long time, the operation risk is increased, or the field of vision is in a blurred state for a long time, which brings inconvenience to the doctor's operation.
