Abstract
Abstract An apparatus for assisting a podiatrist in the performance of various para-medical operations on patients. The apparatus consists of a unit movble on the ground as if a dental unit used by dentists. The work unit includes a pneumatic network, connected to an external air compressor, and to which is connected three tools. Two of these tools include drilling heads, pressurized water outlets and pressurized air outlets, while the third tool includes a pressurized water outlet and pressurized air outlet. Operation of each tool, and of each outlet and drill of a given tool, is made independently of each other, and controlled by a number of knobs, buttons and dials.
