Patent number: 11712305Abstract: Navigated instrument guide systems and related methods can identify an absolute position of an instrument received within an instrument mount of a robotic arm. A navigation array unit of the guide system can include a main array and a mounted array. The main array can identify a position of the robotic arm and the instrument mount, while the mounted array can identify a depth position of a distal end of an instrument received within the instrument mount. The instrument can be passed through a lumen of the mounted array as the instrument is inserted into the instrument mount. The mounted array can be configured to translate relative to the instrument mount and the main array with distal translation of the instrument. In this manner, a position of the mounted array can identify a depth position of the instrument without a mechanical connection between the mounted array and the instrument.Type: GrantFiled: February 7, 2020Date of Patent: August 1, 2023Assignee: Medos International SarlInventors: Joern Richter, Felix Aschmann, Michael Guetlin

Publication number: 20230235765Abstract: A coupling and related methods are disclosed herein that can provide for coupling a first object and a second object with minimal play. A coupling can include a first coupling component having a cylindrical surface with a screw and a pin extending therefrom and a second coupling component having a prismatic surface with a first and a second through-hole. The first coupling component and the second coupling component can be configured such that relative motion between the first coupling component and the second coupling component can be restricted in all six degrees of freedom when the screw is engaged with the first through-hole to secure the cylindrical surface of the first component against the prismatic surface of the second component. The pin can be configured to maintain stability of the coupling and further limit relative movement, such that positioning and/or orientation errors between the first and second components is minimized.Type: ApplicationFiled: March 27, 2023Publication date: July 27, 2023Inventors: Philippe Lindenmann, Felix Aschmann, Rainer Ponzer, Daniela Wehrli

Patent number: 11117197Abstract: Instrument couplings and related methods are disclosed herein, e.g., for coupling a surgical instrument to a navigation array or other component. The coupling can reduce or eliminate movement between the instrument and the navigation array, improving navigation precision. The coupling can be quick and easy to use, reducing or eliminating the need for extra steps or additional tools to attach or detach the instrument from the coupling. In some embodiments, the single step of inserting an instrument into the coupling can automatically lock the instrument within the coupling in a toggle-free manner.Type: GrantFiled: May 31, 2017Date of Patent: September 14, 2021Assignee: MEDOS INTERNATIONAL SARLInventors: Philippe Lindenmann, Felix Aschmann, Daniela Wehrli

Patent number: 10987116Abstract: Adjustable drill guides and related methods are disclosed herein. An exemplary drill guide can include an adjustment mechanism that allows for precise incremental adjustment of the drill guide's depth setting while securely maintaining the device at a fixed setting between adjustments. The adjustment mechanism can improve the safety and security of the drill guide, for example by limiting adjustment only to those situations where it is specifically intended by the user, thereby reducing or eliminating the risk of inadvertent depth adjustment. In some embodiments, a drill guide can include high visibility, easy-to-read depth indications while maintaining a slender profile and without shifting the user's eye gaze, for example by employing a multi-surface moving scale having a text height that is at least twice the adjustment increment. Handles, protection sleeves, navigation adapters, and various other accessories that can be used with or without a drill guide are also disclosed herein.Type: GrantFiled: December 15, 2017Date of Patent: April 27, 2021Assignee: Medos International SarlInventors: Joseph Peterson, Felix Aschmann, John Riley Hawkins

Patent number: 10729476Abstract: An interspinous process spacer for implantation in an interspinous space between a superior spinous process and an inferior spinous process includes a balloon-like body, a first deployable protrusion and a second deployable protrusion. The body has a distal end, a proximal end and a longitudinal axis extending between the proximal and distal ends. The spacer is arrangeable in an unexpanded configuration and an expanded configuration. The first deployable protrusion is mounted proximate the proximal end and the second deployable protrusion is mounted proximate the distal end. The first and second deployable protrusions are oriented generally parallel to the longitudinal axis in the unexpanded configuration and generally perpendicular to the longitudinal axis in the expanded configuration.Type: GrantFiled: March 26, 2018Date of Patent: August 4, 2020Assignee: DePuy Synthes Products, Inc.Inventors: Daniel Thommen, Markus Weber, Jacques Teisen, Markus Kraft, Florian Kaufmann, Markus Hunziker, Felix Aschmann, Stefan Saladin, Martin Oswald, Roman Randegger

Patent number: 10413336Abstract: Provided are methods and systems for enlarging a spinal canal of a vertebra. Using the methods and systems disclosed the spinal canal of the vertebra is enlarged by cutting the posterior arch portion of the vertebra to create one or two implant receiving spaces in the posterior arch portion. The cutting of the posterior arch portion is completed through a minimally invasive approach. Once cut, the detached portion of the posterior arch portion is repositioned and an implant is positioned in the implant receiving space of the posterior arch portion to thereby enlarge the spinal canal such that the spinal cord is no longer compressed. The insertion of the implant is also completed through a minimally invasive approach.Type: GrantFiled: July 6, 2017Date of Patent: September 17, 2019Assignee: DePuy Synthes Products, Inc.Inventors: David Koch, Simon Kamber, Reto Halbeisen, Lukas Giger, Michael Guetlin, Felix Aschmann, Jann-Paul Suedkamp, Marco Messias, Tom Overes, Bruno Laeng, Roger Berger, Joern Richter
