The invention provides a novel surgical minimally invasive surgical instrument and belongs to the field of surgical minimally invasive surgical instruments. The problems that the movement of a radio frequency electrode needs to be guided and positioned to a target area through a C-shaped arm X-ray machine or CT (Computed Tomography) during the current radio frequency electrode operation, an endoscope needs to be matched, the position relation between the endoscope and the radio frequency electrode needs to be coordinated manually, a radio frequency electrode tip is separated from the vision of the endoscope frequently due to the fact that the endoscope cannot follow up in time when the radio frequency electrode moves, and washing and attraction cannot follow up in time can be solved. An endoscope channel, a water inlet tube and a water outlet tube are integrated due to a micro-vision radio frequency electrode casing and accordingly the endoscope, the water inlet tube and the water outlet tube can follow up in time when the position of the radio frequency electrode is adjusted, the relation among the endoscope, the water inlet tube, the water outlet tube and the radio frequency electrode does not need to be coordinated manually, and the radio frequency electrode tip does not need to be guided and positioned to the target area through the C-shaped arm X-ray machine or the CT again. Accordingly, the safety, the convenience and the accuracy of surgical operation are improved.
