Patent number: 10966772Abstract: Various forms of a cable fixation device, instrumentation, kit, and methods useful for repairing the skeletal system are introduced. The system utilizes a clamp housing fixing a head end of a surgical cable therein. In an operative configuration the cable is looped around a damaged bone segment and reentered through a lock aperture in the clamp housing then through a multi-part collet and lock cap residing within a lock aperture. The cable loop and each aforementioned component comprise a central axis aligned within a single plane. A sliding interface situated between the lock cap and collet prevent twisting of the surgical cable. The locking mechanism is non-destructive to the cable despite repeated unlocking and relocking of the fixation device. The axis for tensioning of the cable is coincident with the locking axis. A cerclage inserter instrument is disclosed.Type: GrantFiled: March 2, 2019Date of Patent: April 6, 2021Assignee: J.M. LONGYEAR MANUFACTURING LLCInventors: Matthew Songer, Francis Korhonen, Jeffrey Mosteller, Wesley Leland Hanna, Branden Wainio, Jeffrey Vlahos, Jason Sandstrom, Robert Kinney

Patent number: 10682167Abstract: Instruments are provided for shifting elongate members, such as spinal rods, with respect to coupling members of spinal fixation systems. The instruments include a low friction drive mechanism having one or more rolling elements that ride along a helical groove or track in order to transform rotational movement of a drive member into linear shifting of a reducer member that shifts the elongate member. A one-way locking mechanism may be provided to selectively prevent unwanted counter-rotation of the low friction drive mechanism. The one-way locking mechanism may include annular ratchet teeth arranged on the exterior of the drive member and a ratchet pawl located adjacent to the teeth and selectively engageable therewith.Type: GrantFiled: September 10, 2018Date of Patent: June 16, 2020Assignee: Pioneer Surgical Technology, Inc.Inventors: Jason Sandstrom, Jeffrey Hoffman, Jeffrey D.

Patent number: 10080670Abstract: Instruments, kits, and methods are disclosed for installing an implant spacer through an incision and down a surgical corridor. The instruments also serve to align a drill guide and align and insert a spacer stabilizer for stabilization of adjacent bone portions. The instrument comprises an elongated guide bar body, an inserter face at a distal end of said guide bar body for abutting an instrument attachment portion of a spacer, a connection tip portion for securing a spacer against an inserter face, and a guide portion of said elongated guide bar body for aligning instruments with said spacer and for introducing a stabilizer to secure the spacer in a predetermined position between the bone portions. Included is a retractable graft block for securing graft material within an aperture of said spacer during insertion of the spacer.Type: GrantFiled: February 1, 2017Date of Patent: September 25, 2018Assignee: J.M.
