A battery powered operating table with a removable stationary column base and a detachable table top.

AC and DC powered operating tables were investigated from the viewpoint of safety and the following results were obtained: 1) With the increase in supply voltage, leakage from cables increased prominently. Only a low leakage cable showed a low leakage value. 2) AC powered operating tables showed a high leakage current, especially when in remote control. 3) A battery powered operating table with freely removable driving base and detachable table top function, which we developed, proved to have a satisfactory durability for actual clinical use and an extremely low level leakage of electricity (0.1-0.3 micro A). Moreover, our design incorporates every merit guaranteed by the usual operating table.
