  • Patent number: 11266470
    Abstract: Described herein are systems, apparatus, and methods for precise placement and guidance of tools during surgery, particularly spinal surgery, using minimally invasive surgical techniques. Several minimally invasive approaches to spinal surgeries were conceived, percutaneous technique being one of them. This procedures looks to establish a skin opening as small as possible by accessing inner organs via needle-puncture of the skin. The percutaneous technique is used in conjunction with a robotic surgical system to further enhance advantages of manual percutaneous techniques by improving precision, usability and/or shortening surgery time by removal of redundant steps.
