The difference between the present embodiment and embodiment 1 is that the surgical actuator 3 is a double-stage electric coagulation forceps; the double-stage electric coagulation forceps comprises: the forceps comprise a forceps body consisting of a first bent part 8 and a second bent part 9, electrode holders for respectively supplying power to the first bent part 8 and the second bent part 9, and a driving mechanism for controlling the first bent part 8 and the second bent part 9 to be oppositely clamped or oppositely opened; the first bending part 8 and the second bending part 9 are respectively in a zigzag structure, and a cavity for a cleaning medium sprayed by the hard lens cleaner 4 to pass through is enclosed between the first bending part 8 and the second bending part 9 when the two parts are oppositely clamped. In this embodiment, the positioning sleeve 1 is provided with a sliding channel for accommodating the driving rod 10, and an insulating channel for passing the power supply lines of the first bending portion 8 and the second bending portion 9 respectively. The two-stage electric coagulation forceps are directly arranged on the positioning sleeve 1, and the electric coagulation forceps sleeve 15 is not needed, so that the production cost is effectively reduced.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
