Enhanced Multiple Set Screw Insertion Instrument and Methods

An improved surgical instrument and methods for delivering multiple set screws during spine surgery, enhancing efficiency, safety, and precision.

The original patent disclosed a multiple set screw insertion instrument with limitations in set screw advancement, ergonomic design, and training methods. The new inventive concept addresses these limitations by introducing a spiral groove on the shaft, an improved ergonomic handle design, and a simulator-based training method.

The enhanced instrument features a shaft with a spiral groove, allowing for smoother and more controlled set screw advancement. The ergonomic handle design incorporates a contoured grip and a thumb-activated set screw advancement mechanism with audible and tactile feedback. The system also includes a set screw storage container, designed to work in tandem with the instrument to minimize instrument exchanges. The training method utilizes a simulator with a mock spinal fixation construct and practice set screws to develop surgeon proficiency.

The new inventive concept introduces a spiral groove on the shaft, an improved ergonomic handle design, and a simulator-based training method, which are not obvious from the original patent and provide significant improvements in efficiency, safety, and precision.

Alternative embodiments may include varying the spiral groove design, incorporating different materials or coatings for the shaft and handle, or integrating additional features such as set screw counting or automatic advancement. Variations may also include adapting the instrument for use in other surgical procedures or incorporating the technology into robotic-assisted surgery systems.

The enhanced multiple set screw insertion instrument and methods have significant commercial potential in the spine surgery market, offering improved efficiency, safety, and precision for surgeons and hospitals. The target industries include medical device manufacturers, hospitals, and surgical centers.
