ABSTRACT:
A gel extraction device comprising a hollow cutting member and a plunger ejector member. The hollow cutting member has a proximal tubular body terminating at one end in a circular rim having oppositely disposed spring engaging structures and a distal sloped transition portion ending in a rectangular receptacle and a tapered end portion with a sharp perimeter cutting edge. The plunger ejector member has a proximal cap atop and connected to a split stem portion having outer legs with shoulder stop extensions; an inner ribbon spring leg having a distal end inserted into a spring engaging structure in the assembled device; and a solid rectangular distal portion. In a second embodiment the split end portion is replaced by a stem having a plurality of lateral protrusions and a coiled spring is placed within the hollow cutting member tubular body. A third embodiment is a hybrid of the first two embodiments.
