Intramedullary Screw And Tang For Orthopedic Surgery

Intramedullary Screw And Tang For Orthopedic Surgery

US Patent:
8157801, Apr 17, 2012
Filed:
Feb 9, 2004
Appl. No.:
10/776008
Inventors:
Robert L. Doubler - Ida MI, US
John E. Hammill - Rossford OH, US
International Classification:
A61B 17/56
US Classification:
606 64
Abstract:
One method of reducing fractures in long bones is to insert an intramedullary screw through the bone canal across the fracture and deploy tangs to increase the purchase of the screw. Compression is then applied along the screw to bring the broken bone together. An improved low cost lag screw has a cannulated shaft with a shaped bore in the leading end. A similarly shaped tang body is movably disposed in the leading end bore. The tang body has several tangs laser welded about the periphery and extending from the tang body. The shaped surfaces of the bore have exit holes and the ends of the tangs are adjacent the holes. An end cap is laser welded to the leading end of the shaft.

Internally Disposed Linear Fastener System

Internally Disposed Linear Fastener System

US Patent:
2007002, Feb 1, 2007
Filed:
Sep 8, 2006
Appl. No.:
11/530083
Inventors:
Robert Doubler - Ida MI, US
John Hammill - Rossford OH, US
Assignee:
ZIMMER SPINE, INC. - Minneapolis MN
International Classification:
F16D 1/08
US Classification:
403362000
Abstract:
The present invention provides a linear locking set screw system capable of rapid linear engagement and disengagement. More specifically, the system utilizes a threaded outwardly expandable set screw and an expander member which are constructed and arranged to thread easily into a threaded aperture while in a first release position and can thereafter be securely locked in place and/or provide a secondary clamping force in a second engaged position. In this manner, the linear fastener system is capable of providing a precise, secure, and reproducible connection between multiple components without the need to apply rotational torque to the assembly.

Method Of Making A Bonescrew

Method Of Making A Bonescrew

US Patent:
2001004, Nov 29, 2001
Filed:
Jul 26, 2001
Appl. No.:
09/915775
Inventors:
Robert Doubler - Ida MI, US
John Hammill - Rossford OH, US
Jeffrey Lasner - Purchase NY, US
International Classification:
A61B017/58
US Classification:
606/073000, 606/061000
Abstract:
A screw for use in spinal and other surgical procedures has a tapered core and fixed pitch threads. The threads have a compound curved inferior surface and constant width crest. The screw may be provided with a helical thread in which at least the lead thread adjacent to the screw tip is ledged and the following threads have sharp apices. A method of making the screw requires two tool bits making two different angular cuts to the inferior surface of the threads.

Spinal Fixation Assembly

Spinal Fixation Assembly

US Patent:
2005013, Jun 23, 2005
Filed:
Aug 5, 2004
Appl. No.:
10/912532
Inventors:
Robert Doubler - Ida MI, US
John Hammill - Rossford OH, US
International Classification:
A61B017/56
US Classification:
606061000
Abstract:
This disclosure relates to spinal fixation assemblies for use in spinal fixation constructs. The final fixation assemblies include fastening arrangements for clamping components of the assemblies at desired positions. The fastening arrangements are moved from pre-finally clamped orientations to finally clamped orientations through the use of linear force. An installation tool can be used to inhibit linear force from being transferred to the patient.

Spinal Plate With Internal Screw Locks

Spinal Plate With Internal Screw Locks

US Patent:
7322984, Jan 29, 2008
Filed:
Jan 6, 2005
Appl. No.:
11/031143
Inventors:
Robert L. Doubler - Ida MI, US
John E. Hammill - Rossford OH, US
Assignee:
Spinal, LLC - Toledo OH
International Classification:
A61B 17/58
US Classification:
606 69
Abstract:
A bone plate for stabilizing adjacent vertebrae or ends of a bone has a span for extending across the discontinuity. The span has brackets for attaching to the bone. The brackets have countersunk apertures terminating through which bone screws are placed in the bone. An eccentric cam bore is located between the countersunk apertures and, upon rotation of an eccentric cam, wedge grip shoes are slid into the countersunk apertures and frictionally engage the spherical heads of the bone screws. To prevent back-out of the bone screws, the eccentric cam is locked into the wedge grip shoes.

John E. Hammill - Rossford OH
Assignee:
Hammill Manufacturing Co. - Toldeo OH
International Classification:
A61F 232
US Classification:
623 2318
Abstract:
A modular prosthesis has an intramedullary rod element which is to be inserted in a bone. The rod has a shaped proximal portion which is telescoped into one end of a bore in the trochanter element. The mating surfaces of the shaped rod and the trochanter bore form a rotationally immovable connection. A neck element is telescoped into the other end of the trochanter bore permitting rotational adjustment. All the elements are locked together by a bolt through the neck and rod.

Assignee:
Spinal, LLC - Toleda OH
International Classification:
A61B 17/56
US Classification:
606 61, 606 60
Abstract:
A low profile orthopedic device is used to fix and stabilize bones to correct anomalies in skeletal structure occurring naturally or by trauma. Bone screws are screwed into bones by application of torque. Clamps are movably attached to the screws. Each clamp includes a compression ring. A connecting rod connects several screws through slots in the clamps. The clamps are tightened to hold the rod and the heads in a pre-selected position by linear movement of the compression rings.
