Publication number: 20240225775Abstract: An adapter for removably coupling a tracker to a surgical handpiece includes a proximal member having an interface configured to engage and prevent rotation of the proximal member relative to the surgical handpiece, a distal member slidably and rotatably coupled to the proximal member, a biasing member disposed between the proximal distal members and configured to urge the proximal and distal members in opposing directions, and a tracking array mount coupled to the distal member. The biasing member is configured to be compressed by a reference feature of the end effector and the surgical handpiece when the distal member is disposed on the end effector and the end effector is coupled to the surgical handpiece, the compressed biasing member creating a frictional force between the distal and proximal members that resists rotation of the distal member relative to the proximal member.Type: ApplicationFiled: February 25, 2022Publication date: July 11, 2024Applicant: Stryker European Operations LimitedInventors: James G. Walen, Rahul Eapen, Clifford Edwin Lambarth, Caleb Gossens, Fadi Ghanam, Michael Laubenthal, John Andrew Snodgrass

Patent number: 9642653Abstract: A minimally invasive spinous process fixation system includes dual rigid spinous clamps, each configured to articulate axially along a cylindrical shaft, and together configured to enclose and clamp around the adjacent or superior spinous process by means of opposing and swiveling spherical contact heads with spiked spinous contact faces. The spinous clamps are lockable when desired compression is achieved. A pedicle clamp has right and left clamp bodies for enveloping pre-existing pedicle rods. Each of the right and left clamp bodies includes upper and lower rigid metal plates supporting medial and lateral swivel cups. The upper and lower medial swivel cups engage and clamp about a connecting rod extending from the spinous clamp, and the upper and lower lateral swivel cups engage and clamp about one of the pedicle rods. A channel through the upper and lower metal plates accepts a locking screw to simultaneously tighten and fix the swivel cups in place about the connecting rod and the pedicle rod.Type: GrantFiled: September 11, 2013Date of Patent: May 9, 2017Assignee: Mercy Medical Research InstituteInventors: Alan Scarrow, Vinoth Sivapatham, Martin Reuter, Rahul Eapen, Keela Davis

Patent number: 9101533Abstract: A needle safety guard device adapted to attach to a liquid container is provided. The device includes a disk-shaped shield having a medial opening connected with a radial opening between two radial edges. The device also includes a substantially U-shaped holder having two sidewalls coupled substantially perpendicular to the disk-shaped shield along the two radial edges, and a top cover connecting to the two sidewalls and extending from the shield above the radial opening. The U-shaped holder includes a wedged protrusion and a curved protrusion extending from each of the two sidewalls, the curved protrusion being between the top cover and the wedged protrusion for blocking a cap of the liquid container from moving toward the medial opening.Type: GrantFiled: May 7, 2013Date of Patent: August 11, 2015Inventors: Bruce Hedgepeth, Roger Huckfeldt, Cindy Lowe, Martin Reuter, Matt Price, Keela Davis, Rahul Eapen

Patent number: 9081207Abstract: The eyeglass frame is an improved eyeglass frame with dislocating joints. The dislocating joints prevent damage to the eyeglass frame when external forces are applied to the structure and allow for the frame to be disconnected, if so desired. The joints dislocate without completely separating from the other components of the eyeglass frame or becoming damaged, and the joints can be quickly reconnected without tools.Type: GrantFiled: March 6, 2013Date of Patent: July 14, 2015Assignee: Mercy Medical Research InstituteInventors: Scott Atkinson, Martin Reuter, Rahul Eapen

Publication number: 20150059770Abstract: Novel tools, accessories and methods for fixing a patient's upper and lower jaws together with flexible straps are disclosed. The tools are intended to either allow placement of a flexible strap to bind items to the teeth, or for using a flexible strap to fasten the upper and lower jaw into place, among other purposes. These accessories include a washer with a ratchet head for mounting on a bone screw, a bone screw with integrated ratchet head, dental blocks for use with the bone screws and washers, a flexible strap provided with a dissection tip for forcing the strap through tissue, and combinations thereof, and tools for inserting flexible straps through the gums, among other tools and accessories.Type: ApplicationFiled: August 29, 2014Publication date: March 5, 2015Inventors: Bharat Shah, Keela Davis, Anna Kelley, Rahul Eapen
