Patent number: 11627952Abstract: In one aspect, a surgical retractor having sliders configured to have tissue engaging members connected thereto and slider drives including operating members. The operating members are rotatable to cause the slider drives to shift the sliders relative to one another. The surgical retractor includes a coupler having a coupling configuration wherein the coupler connects the slider drives and rotation of one of the operating members causes movement of the sliders. The coupler also has a decoupling configuration wherein the coupler disconnects the slider drives and rotation of the one operating member causes movement of fewer sliders than the sliders that are moved with the coupler in the coupling configuration. The retractor has an actuator connected to the coupler and movable between a dependent slider movement position and an independent slider movement position to shift the coupler between the coupling configuration and the decoupling configuration.Type: GrantFiled: June 28, 2021Date of Patent: April 18, 2023Assignee: Surgalign Spine Technologies, Inc.Inventors: Stephan Eckhof, Matthew P. Gephart, Kale Reid, Markus Salvermoser, Matthew Allan Stilwell, Daniel Wefers, Marc Mundhenke

Patent number: 11298172Abstract: Instruments for applying tension to a securing device, such as a cable or wire, for securing bones in place and fastening implants, such as plates, to bones. In some forms, the tensioning instrument is configured with minimal parts for ease of manufacturing and allowing single use applications. The instrument may include a pretensioning mechanism for applying desired preload before connecting a cable to be tensioned to the instrument. The instrument may be sized and configured to remain attached to a tensioned cable while other cables are connected to a bone. In another form, the instrument may be expandable to remove any slack from the securing device and apply tension thereto.Type: GrantFiled: May 15, 2019Date of Patent: April 12, 2022Assignee: A&E Advanced Closure Systems, LLCInventor: Matthew P.

Publication number: 20220071668Abstract: A multi-stage minimally invasive surgical procedure and associated instruments are disclosed. First, the surgical site is prepared. After preparation, the bone screws or anchors are attached to the bone. Subsequent to insertion of the screws, a rod or connecting member is positioned within the yoke portion of the bone screw. Caps are then placed in a pre-lock position within the yokes. The bone screws may be compressed together or distracted along the rod or connecting member, thereby setting the final spacing of the bones or bone segments. Finally the caps are moved to a final lock position to fix the screws to the rod or connecting member to maintain the bones in position relative to each other.Type: ApplicationFiled: August 9, 2021Publication date: March 10, 2022Inventors: Matthew P.
