Patent number: 11534184Abstract: Described herein are systems and apparatus of surgical instruments engineered for integration with robotic surgical systems to enhance precision in surgical procedures. Also described herein are methods of using such surgical instruments in performing surgical procedures. The use of such surgical instruments reduce complications arising from misalignment during surgery. The disclosed technology assists in stages of a surgical procedure that require a precise trajectory to be followed. Surgical instrument guides are attached to a universal surgical instrument guide, which is engineered to attach directly or indirectly with a robotic arm of a robotic surgical system. Surgical instruments can then be precisely guided along an axis defined by the universal surgical instrument guide. Individual instruments are easily inserted and removed from the channel of the universal surgical instrument guide, thus allowing a range of instruments to be used throughout a procedure while maintaining the surgical trajectory.Type: GrantFiled: September 22, 2020Date of Patent: December 27, 2022Assignee: Globus Medical, Inc.Inventors: Olivier Chappuis, Szymon Kostrzewski

Patent number: 11458028Abstract: A system and method for improving installation of a prosthesis, particularly an acetabular cup. The system and method may include implementation of a constant velocity relative motion between a prosthesis and an installation site. For example, an installation system may be fixed relative to the installation site, with the prosthesis fixed into an initial position. The prosthesis is moved at constant speed (i.e., with minimal if any acceleration or applied impulses) relative to the installation site. That is, one or both of the prosthesis or the installation site may be in motion. Resistive forces to installation of a prosthesis may thus be reduced by maintaining the prosthesis constantly in motion relative to the installation site. Securing a processing/implanting tool directly to the installation site may offer advantages.Type: GrantFiled: September 27, 2017Date of Patent: October 4, 2022Inventor: Kambiz Behzadi
