|発明の名称||CLEANING DEVICE FOR ENDOSCOPIC SURGICAL INSTRUMENT|
PROBLEM TO BE SOLVED: To provide a new cleaning device for an endoscopic surgical instrument, capable of easily, appropriately and immediately cleaning up the endoscopic surgical instrument during an operation, or before or after the operation, not only when a "solid-liquid" interface is formed but also when a "solid-gas" interface is formed, and capable of relieving the stress felt by an operator caused by the deterioration of the visual field.
SOLUTION: The cleaning device 1 for the endoscopic surgical instrument comprises a low-pressure air-tight chamber 2 having an insertion hole 21 with an air-tightness retaining sealing membrane 22 and a connector 23 to be connected to an outside device, and a cleaning liquid holding tank 3 with a nozzle tube 4 with a nozzle 41 disposed inside in such a state that the nozzle 41 is turned upward. The low-pressure air-tight chamber 2 as an upper unit of the cleaning device 1 and the cleaning liquid holding tank 3 as a lower unit of the cleaning device 1 are connected to each other with the insertion hole 21 and the nozzle 41 facing each other.
