A medical guidance apparatus () includes a base assembly () configured to be attached to a subject and a guide () configured to be removably mated with the base assembly (). The base assembly () has an opening (), and the guide () includes a rotatable ring () and an arc member (). The arc member () includes a first end () and a second end (), the first end of the arc member is connected to the rotatable ring () and the second end extends diametrically opposite to the first end across the rotatable ring. A probe holder () is mounted on the arc member () so as to hold a needle-like instrument () at a desired angle relative to an axis (Ax) of the rotatable ring (). In some embodiments, the arc member is monolithically integrated with the rotatable ring. In other embodiments, the arc member is pivotable and/or completely removable from the rotating ring.

Medical tool guidance apparatus

A system and method for supporting multi-probe guidance are disclosed. The system comprises: a medical guidance apparatus comprising: a rotatable portion which is rotatable around a first axis; an arc guide attached to or integrally formed with the rotatable portion, and a probe holder movably mounted on the arc guide. The probe holder is rotatable around a second axis perpendicular to the first axis by being translated along an arcuate path defined by the shape of the arc guide. In one embodiment, the probe holder includes a plurality of probe channels to guide a corresponding plurality of probes parallel to each other towards a subject. In other embodiment, the probe holder includes a single probe channel which is offset from a center point of the guidance apparatus by a fixed distance such that each probe can be inserted sequentially through a different insertion point without colliding at the center point.
