ABSTRACT:
An instrument for inserting a plurality of hollow needles into a body for interstitial radiotherapy comprising a unit having a pair of elongated members each having first and second ends and providing clamping portion at the first ends and a handle at the second ends. The members are pivotally connected intermediate their ends for movement between closed and opened conditions by actuation of the handle, and the clamping portion engages the needles when the members are in the closed condition and disengages and releases the needles when the members are in the opened condition. Needle retaining means secured with the unit slidably receives the plurality of needles which are controllably engaged by the clamping portion of the unit and includes a needle aligning device having a plurality of openings for positioning the needles in parallel relation to each other within the same plane and stop for engaging the back ends of the needles for adjusting the extension of their sharpened front ends beyond the clamping portion.
