Patent number: 7243580Abstract: A driver has components that are easily disassembled for cleaning and/or sterilization. Once disassembled, the limited number of components allows for easy reassembly. The driver utilizes a cam that rides on spring fingers for determining the level of producible torque that the driver can produce. The cam and spring fingers are contained in a housing. Particularly, the spring fingers are part of a finger housing that is key lockable with the housing when assembled for movement as one unit. The cam is integral with a driver shaft and is received within the finger housing. The cam and driver shaft are limitedly rotatable with respect to the finger housing. The level of producible torque may be changed by providing cams and/or spring fingers of various dimensions. The driver is torque-limiting in one direction (tightening) and essentially non torque-limiting in the opposite direction (loosening). The various components are also large enough to be easily handled reducing the chance of lost components.Type: GrantFiled: December 23, 2003Date of Patent: July 17, 2007Assignee: DePuy Products, Inc.Inventor: Edmund W. Frazee

Publication number: 20070162011Abstract: A bone fixation assembly includes a side plate for mounting on a bone and a barrel for receiving a portion of a lag screw, and configured to be inserted into a hole in the side plate. A mechanical spring located at the upper portion of the barrel biases a first detent portion toward a locking position with a second detent portion located on the side plate such that rotation of the barrel within the hole from a first position to a second position causes a compressing portion on the detent portion to contact a compressing portion on the second detent portion thereby compressing the mechanical spring so as to allow the barrel to be rotated to a third position wherein the mechanical spring is allowed to bias the first detent portion into the locking position such that a retaining portion of the first detent is adjacent to a retaining portion of the second detent and rotation of the barrel with respect to the side plate is restricted.Type: ApplicationFiled: December 16, 2005Publication date: July 12, 2007Applicant: DePuy Products, Inc.Inventors: Matthew Leyden, William Ryder, Wesley Johnson, Aaron Bisek, Marc Ruhling, Matthew Wallace
