a scalpel head, a transport conduit, a fluid supply means, and a fluid connector as defined in any one of claims 1 to 7; wherein,
the transmission pipeline is respectively connected with the scalpel head and the fluid connector;
the fluid connector is connected with the liquid supply device;
and the liquid supply device is used for driving liquid to enter the scalpel head through the fluid connector and the transmission pipeline and then to be sprayed out.
10. The surgical operating system of claim 9,
the liquid supply device comprises: a reservoir, a movable plunger structure, and a cam; wherein,
the water storage container is fixedly connected with a main pipe of the fluid connector;
the inner surface of the reservoir is in contact with the outer surface of the movable plunger structure, and a sealed reservoir space exists between the reservoir and the movable plunger structure;
the movable plunger structure is connected with the cam;
the cam is connected with an external power device and can rotate under the target power provided by the external power device to drive the movable plunger structure to reciprocate in the water storage container, so that the liquid stored in the liquid storage space of the water storage container is sprayed out after entering the scalpel head through the fluid connector and the transmission pipeline.
