Publication number: 20240024010Abstract: Instruments and related methods for breaking reduction tabs are disclosed herein, e.g., for breaking reduction tabs of a bone anchor or other implant. In some embodiments, the instrument can be configured to minimize the space needed to operate the instrument. For example, the instrument can be configured to receive a reduction tab that is to be broken while the instrument is coaxially positioned with respect to a bone anchor receiver to which the reduction tab is attached. As another example, the instrument can have a maximum outer transverse dimension that is less than, equal to, or only slightly greater than a corresponding dimension of a bone anchor from which a reduction tab is to be broken. Guide rods for positioning a tab breaker instrument over a reduction tab are also disclosed.Type: ApplicationFiled: July 26, 2023Publication date: January 25, 2024Inventors: Seetal Erramilli, Frank Spratt, Grant Mellor, Chris Culhane, Ben Stungo, Joanna Talis

Patent number: 11678894Abstract: Disclosed is an instrument for balancing a knee. The instrument has a first plate (10) coupled to a second plate (50) by a plurality of adjusters (152A, 152B, 152C). The adjusters are actuatable to vary the gap between the first and second plates. Each adjuster is coupled to the second plate by a joint having at least two degrees of freedom. Also disclosed is an outrigger (300). The outrigger includes a body featuring a connection component configured to be received and held by a slot (34) of the instrument. The slot is arranged to align a blade of a surgical saw with a portion of a knee to be cut. Also disclosed is a method of balancing a knee using the instrument and a method of fabricating the instrument.Type: GrantFiled: December 14, 2018Date of Patent: June 20, 2023Inventors: Chris Culhane, Peter J McMahon, Grant Mellor

Patent number: 9949731Abstract: Systems and methods are disclosed in which a distraction sleeve can be attached to a bone anchor assembly to lock or limit the polyaxial degree of freedom of the bone anchor assembly and facilitate true parallel distraction. In some embodiments, the distraction sleeve can lock polyaxial movement of the bone anchor assembly without directly engaging the shank of the bone anchor assembly, without directly engaging the exterior of the receiver member of the bone anchor assembly, and/or without requiring that a rod or closure mechanism be installed in the bone anchor assembly. The distraction sleeve can be preloaded onto the bone anchor assembly prior to inserting the bone anchor assembly using a selectively detachable driver, thereby providing simplified, streamlined insertion and facilitating use with protection and/or retraction sheaths. Countertorque tubes, torque wrenches, and other related instrumentation are also disclosed herein.Type: GrantFiled: October 7, 2015Date of Patent: April 24, 2018Assignee: Medos International SàrlInventors: Seetal Erramilli, Grant Mellor, Frank Spratt

Patent number: 7763021Abstract: An intramedullary nail assembly comprises an intramedullary nail component (2) al, the nail component having at least one opening (14, 18) in its wall, and a fixation sleeve which has at least one opening (32) extending through it. One of the fixation sleeve and the nail component has a hollow bore so that the other of the sleeve and the nail component can be fitted within it in a coaxial sliding arrangement, with the openings in the wall of the nail component aligned with the openings in the fixation sleeve. A fixation pin (19) is inserted transversely through the openings in the wall of the nail component and the fixation sleeve when the said openings are aligned. An actuator (50) is used to cause the fixation sleeve to move axially relative to the nail component to cause a fixation pin inserted through the aligned openings in the nail component and the fixation sleeve to be gripped.Type: GrantFiled: May 17, 2004Date of Patent: July 27, 2010Assignee: Depuy International LimitedInventors: Dean J Cole, Michael Barker, Henri Defossez, Grant Mellor, James Brooks
