Patent number: 6866667Abstract: A patellar milling clamp is provided with a depth control for limiting and controlling the milling depth of a grater rotated against a bone secured in the milling clamp. A stop ring is provided on a shaft of the milling tool. The shaft is slidable in a guide bushing of the milling clamp, and a rotatable cap on the guide bushing is selectively engaged in notches in the guide bushing to provide an abutment surface at selectively different elevations. Further advancement of the tool is prevented when the stop ring abuts the abutment surface of the cap. The depth of milling is precisely controlled regardless of the original thickness of the patellar bone being milled.Type: GrantFiled: September 3, 2002Date of Patent: March 15, 2005Assignee: Symmetry Medical, Inc.Inventors: Steven R.

Patent number: 6250858Abstract: In the broader aspects of the invention, there is provided a new and improved tool driver having a shaft with a longitudinal axis and opposite ends and tools therefor. A boss is secured at one of said shaft ends by which the tool driver is connected to a rotary tool. A tool collate is secured at the other of the shaft ends by which the tool driver may be driven by a surgical hand piece having a chuck in which the collate may be positioned. The boss has a surface which engages the tool and positions the tool exactly coaxially of the tool driver. A latch mechanism is provided to hold the rotary tool on the boss, whereby the rotary tool is held exactly coaxially of the driver during use. The rotary tool which is used with the driver has a bottom tool driver opening which has the same dimensions as the boss of the tool driver of the invention. The boss thus fills the opening and the opening is complementary to the boss.Type: GrantFiled: August 4, 1999Date of Patent: June 26, 2001Assignee: Othy, Inc.Inventor: Paul E. Salyer

Patent number: 5980170Abstract: A new and improved tool driver having a shaft with a longitudinal axis and opposite ends. A boss is secured at one of said shaft ends by which the tool driver is connected to a rotary tool. A tool collate is secured at the other of the shaft ends by which the tool driver may be driven by a surgical hand piece having a chuck in which the collate may be positioned. The boss has a distal end surface with a groove therein. Both the groove and the distal end surface extend transversely of the axis. A pin is positioned in the groove on the axis. A latch mechanism is provided to hold a mounting bar of a rotary tool in the groove on the pin, whereby the rotary tool is held exactly coaxially of the driver during use. The rotary tool which is used with the driver has a bar which has the same dimensions as the groove in the boss of the tool driver of the invention. The bar thus fills the slot and is complementary to the slot. The bar has a hole therein which is complementary to the pin.Type: GrantFiled: March 27, 1998Date of Patent: November 9, 1999Assignee: Othy, Inc.Inventor: Paul E. Salyer
