Patent number: 9492179Abstract: An assembly for guiding resection of a femur and tibia of a knee joint in preparation for installing a femoral and tibial knee components. For example, the assembly can include tibial and femoral IM rods to which are connected through a tensioning bolt that allows controlled adjustment of the distraction of the tibia and femur during cut positioning in a range of flexion angles. Also, the assembly is usable with relatively small, noninvasive approaches to the knee joint by way of relatively narrow, low profile components that attach to tibial and femoral IM rods. Further, the assembly includes several quick-release components to allow fast assembly and disassembly in a surgical setting. Each of these aspects, along with the ability of the assembly to accurately guide initial reference cuts to the tibia and femur, promotes an improved outcome for the patient.Type: GrantFiled: November 5, 2012Date of Patent: November 15, 2016Assignee: OTSUKA MEDICAL CO., LTD.Inventor: G.

Patent number: 9474470Abstract: An instrument for establishing orientation of a pelvic prosthesis comprises a tripod having an angularly adjustable guide rod on it. The tips of the legs define a plane, and the guide rod is set by the surgeon to a defined orientation with respect to this plane on the basis of preoperative studies. In use, two of the legs of the instrument are positioned by the surgeon at defined anatomical locations on the pelvis (e.g., a point in the region of the posterior/inferior acetabulum and a point on the anterior superior iliac spine). The third leg then lands on the pelvis at a point determined by the position of the first two points, as well as by the separations between the third leg and the other two legs. The position of the guide rod then defines with respect to the actual pelvis the direction for insertion of a prosthesis.Type: GrantFiled: June 22, 2015Date of Patent: October 25, 2016Inventor: Stephen B.

Patent number: 9402672Abstract: A joint distraction device for use in an arthroscopic surgery is provided. The device has a joint distraction mechanism, situated in between two bone fixation surfaces, and is capable of changing the relative distance between these two surfaces. The force generated by the mechanism should be sufficient to insert bone spikes affixed to the surfaces into bone, as well as distract the joint to create a sufficient enough gap to allow the intended procedure. With the surfaces and spikes engaged to bone at opposite sites of a joint, an increase in distraction force results in an increase in the relative distance results, hence increasing the space within the joint. Embodiments of this invention, compared to fracture table approaches, effectively eliminate the risk of pudendal nerve injury, allow for longer surgical times, and allow for much more controllable joint distraction.Type: GrantFiled: October 31, 2014Date of Patent: August 2, 2016Assignee: THE BOARD OF TRUSTEES OF THE LELAND STANFORD JUNIOR UNIVERSITYInventors: Eric Fayez Chehab, Archana Appukuttan Nair, Chad Alexander Sitgraves, Marc Raymond Safran

At least one insertion guiding structure is movably supported by the guide base and is adjustable into a guiding configuration in which at least one of the predetermined insertion trajectory and the predetermined insertion location is selectively imparted to the directed structure.Type: GrantFiled: April 10, 2013Date of Patent: May 19, 2015Assignee: The Cleveland Clinic FoundationInventors: Joseph P. Iannotti, Wael K. Barsoum, Jason A. Bryan

Patent number: 9033989Abstract: A surgical cutting guide is described which can guide a cutting implement to cut in a pair of planes at a defined relative orientation. The cutting guide comprises a first plate defining a first cutting plane, a second plate defining a second cutting plane at an angle to the first cutting plane; and a base member to which both the first plate and the second plate are attached. The first and second cutting planes intersect each other at a line of intersection and both the first plate and the second plate extend beyond the line of intersection.Type: GrantFiled: June 4, 2012Date of Patent: May 19, 2015Assignee: DEPUY (IRELAND)Inventors: David Wolfson, Duncan Young, Michael Rock, Andrew Bailey, Charles Christie

Publication number: 20150134060Abstract: A system is disclosed for repairing and reconstructing an injured intra-articular, extra-articular ligament or tendon to a bone. The system includes realigning the axis of a bone, and further includes fixing fragments of a bone together. Novel devices, instruments and methods are disclosed, including a cortical loop for engaging a bundle of soft-tissue and capturing the bundle against a bone surface, an anchor for stabilizing a fractured bone, a guide for directing an orthopedic blade, and a hinged external jig arranged to position and guide the blade. Methods are disclosed for connecting soft-tissue to a bone and for bone alignment.Type: ApplicationFiled: November 12, 2013Publication date: May 14, 2015Inventor: Steven C. Chudik

Patent number: 9023054Abstract: A surgical resection guide comprising: a housing (36); a stylus arm (38) extending through the housing (36) arranged such that when the housing (36) is coupled to the side of a bone, a tip of the stylus arm (38) is arranged to contact an end of a bone; and a linear adjustment mechanism. The linear adjustment mechanism comprises: a shaft (30) at least partially received within a bore extending through the housing (36) such that the shaft (30) can slide along its longitudinal axis relative to the housing (36), the shaft (30) incorporating a shaft tooth or groove (50); and a dial (44) rotatably coupled to the housing (36) and incorporating a helical dial groove or rib (48) defining a longitudinal axis offset from the longitudinal axis of the shaft (30).Type: GrantFiled: April 14, 2014Date of Patent: May 5, 2015Assignee: Depuy (Ireland)Inventors: Dean Cowan, Duncan Young

Patent number: 9023053Abstract: A system for performing a resection of a selected portion of an anatomy with a resection instrument. The system includes a first member, a first movement defining portion defined by the first member, a second member, and a second movement defining portion of the second member. The first member is fixable to the selected portion of the anatomy. The second member is configured to cooperate with the first member. The first movement defining portion and the second movement defining portion are operable to allow the second member to be moveable relative to the first member from a first position to a second position. The resection instrument is positionable relative to the second member in the first position and in the second position to form a selected resection of the selected portion of the anatomy.Type: GrantFiled: October 7, 2013Date of Patent: May 5, 2015Assignee: Biomet Manufacturing, LLCInventor: Robert Metzger

Patent number: 9017334Abstract: A resection guide locator includes a bone engagement portion with surfaces that are complementary to the surface topographies of a bone to be resected during surgery. A housing includes a socket defined by a resilient annular wall that is sized and arranged so to accept a resection guide by press-fit to thereby position and hold the resection guide within the socket. The resection guide is maintained in a predetermined, preferred position while the surfaces are releasably locked in position on the bone. A method is disclosed for forming and using the resection guide locator.Type: GrantFiled: February 23, 2010Date of Patent: April 28, 2015Assignee: Microport Orthopedics Holdings Inc.Inventors: Michael Carroll, Richard Obert, Paul Stemniski
