ABSTRACT:
In one aspect, the invention provides a surgical handle assembly including an elongate cylindrical sheath having a proximal end, a distal end, and a central lumen therebetween. A chuck member is slidable within the sheath lumen, with the chuck member having a proximal end and a distal end. The proximal end is threaded, and a set of at least two prongs are disposed at the distal end. A threaded end element is provided for mating with the proximal threaded end of the chuck member such that rotation of the end element relative to the chuck member proximally translates the chuck member within the lumen to translate the prongs toward each other as the prongs engage the distal end of the cylindrical shaft.
