Patent number: 11937857Abstract: Bone anchors and surgical instruments (e.g., bone taps, drivers, etc.) are disclosed herein that include integrated guide tips. Use of these anchors or instruments can eliminate one or more of the steps in a conventional bone anchor installation procedure, improving surgical efficiency and safety. For example, a surgical instrument can include a guide projection configured for insertion through a cannulation formed in a bone anchor when the surgical instrument is coupled to the bone anchor. The surgical instrument can also include various mechanisms for adjusting the position of the guide projection relative to the bone anchor. The guide projection can replace the needle, stylet, and guidewire used in typical insertion procedures. The bone anchor can also include integrated tapping features to eliminate the need for a separate bone tap instrument. Thus, in some embodiments, targeting, tapping, and driving the bone anchor can be performed in a single step.Type: GrantFiled: September 29, 2022Date of Patent: March 26, 2024Assignee: DePuy Synthes Products, Inc.Inventors: Christopher Ramsay, John DiVincenzo, Nicholas Pavento

Publication number: 20240092585Abstract: A support link for a self-stacking spiral conveyor belt, which includes a carrier on which a self-stacking spiral conveyor belt is supportable, a set of orthogonally arranged rolling elements connected to the carrier, in use to guide the carrier along a conveyor path and an interlink mountable onto the carrier. The interlink is connectable to a matched interlink of an adjacent support link through couplers disposed on opposing ends thereof, whereby the connection of a plurality of support links results in a support chain. Furthermore, there is provided a supporting frame defining the conveyor path on which the support chain is movable and a motor driving the support chain by means of a drive gear, which interacted with a drive interface disposed on each support link.Type: ApplicationFiled: January 20, 2022Publication date: March 21, 2024Inventors: Christopher DALE, Francois KRIEL, Lyle RAMSAY
