NO WIRES ON RADIO KNIFE (Mar, 1933)

Wow, that looks …um… positively terrifying!

NO WIRES ON RADIO KNIFE
Surgeons hail a new radio knife, devoid of wires, as an outstanding advance. Previous types have long employed high-frequency currents like those of radio, led through a dangling cord, to make clean, bloodless cuts in tissue. The latest apparatus dispenses with any electric connection and leaves the surgeon’s hands unencumbered in a delicate operation. An insulated electrode behind the patient’s back charges his skin, and the surgeon’s scalpel absorbs enough energy at the
point of contact to divide the tissues cleanly.
