Abstract:
1. A surgical instrument comprising: a monolithic first member extending between a proximal end and a distal end, the distal end including a plurality of fingers extending radially outward in a tapered configuration, the fingers each including an inner surface such that the inner surfaces of the fingers jointly define a socket; a second member extending between a proximal end and a distal end, the proximal end of the second member having a bit configuration defined by a plurality of substantially planar side surfaces, the proximal end of the second member being configured to be received within in the socket such that the side surfaces engage the inner surfaces to prevent rotation of the second member relative to the first member; and a third member having an inner surface defining a cavity, the cavity configured to receive and move the fingers of the first member thereby fixing the first member to the second member, wherein the first member includes a first thread form and the third member includes a second thread form, the thread forms being engageable to fix the first member with the second member.
