  • Patent number: 5713905
    Abstract: A modular surgical drill in the form of a rigid drill shaft and a drill bit which are connected together at the rear end of the drill bit and the forward end of the drill shaft by a tongue-and-groove arrangement. Each of the shaft and drill bit are provided with through bores extending centrally through their entire length. These bores become aligned upon assembly of the drill bit and shaft. The modular drill is intended to be employed with a guidewire for drilling holes into bone. The assembled drill bit and shaft are placed on the guidewire and moved down such guidewire into contact with the bone, whereupon a tunnel may be formed into the bone by rotating and advancing the drill bit along the guidewire. The dimensions of the bore and guidewire are so selected as to prevent the drill bit and drill shaft from moving relative to one another once they are assembled and mounted upon the guidewire.
