ABSTRACT:
An instrument for inserting one or more hollow needles into the body for interstitial radiotherapy of malignant tumors, which permits the incremental advancement of a needle by means of a reciprocating tubular element having a collapsible end portion which alternately grips the needle to advance it into the body, and releases the needle to permit the instrument to be moved back on the needle to a new position to again advance it further into the body. The instrument permits the insertion of a needle with only one hand, freeing the other hand to both support the area being implanted and to maintain a continuous stereotactic guidance of the advancing needle, as well as facilitating implanation of long and closely spaced needles deep within the body.
