This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,178.

Summary of the Inventive Concept

The present invention relates to an improved surgical suturing instrument that incorporates ergonomic design elements to reduce user fatigue, ensures proper sterilization, and provides versatility in accommodating various suture materials and sizes.

Background and Problem Solved

The original patent, 'Surgical suturing instrument,' addresses the need for efficient suturing during surgical procedures. However, the existing design has limitations, including user fatigue, potential contamination, and restricted suture material options. The new inventive concept solves these problems by introducing an ergonomic grip, a sterilization indicator, and couplers that accommodate diverse suture materials and sizes.

Detailed Description of the Inventive Concept

The advanced surgical suturing instrument comprises a handle, grasping mechanism, first jaw, second jaw, first coupler, second coupler, first strand, second strand, shaft, and cutter. The ergonomic grip is designed to reduce user fatigue during prolonged use. A sterilization indicator ensures the instrument is properly sterilized before use. The first coupler and second coupler are designed to accommodate a variety of suture materials and sizes, increasing the instrument's versatility. The instrument can also be used in conjunction with a computer-assisted guidance module to facilitate accurate suture placement and minimize tissue damage.

Novelty and Inventive Step

The new inventive concept introduces the ergonomic grip, sterilization indicator, and versatile couplers, which are not present in the original patent. These features provide significant improvements in user experience, safety, and instrument adaptability.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying ergonomic grip designs, different sterilization indicator mechanisms, or adjustable couplers to accommodate a wider range of suture materials and sizes.

Potential Commercial Applications and Market

The advanced surgical suturing instrument has significant commercial potential in the medical device industry, particularly in the fields of general surgery, orthopedics, and cardiovascular surgery. The instrument's enhanced ergonomics, sterilization features, and versatility in accommodating diverse suture materials and sizes make it an attractive solution for surgeons and medical professionals.
