The PAKY needle driver holds, orients, and actively drives a needle (typically 18G or thinner). It is made of a few simple plastic components (sterile and disposable). These also provide radiolucency, so that the driver does not impede the radiological visualization of the target. In this version PAKY is directly supported by a passive arm, manually oriented and locked in place, and needle insertion is performed under joystick control.
