What This Patent Covers

This patent protects a surgical forceps design featuring a working tip, support, bending section, straight section, and operating unit, all sequentially connected. It specifically covers the use of superelastic wires for both the working wire (0.5mm diameter or less) and three or more bending wires. The successful overcoming of examiner rejections, combined with zero cited prior art, indicates a robust patent with low invalidation risk.

Competitive White Space

This patent primarily covers the mechanical design and material composition of the forceps. White space exists in integrating advanced imaging or AI-driven haptic feedback systems, and developing specific therapeutic applications beyond general manipulation.

ROI Calculation Logic

Assuming a 10% reduction in average complex minimally invasive surgery time. If the average labor and equipment operating cost per surgery is ~$5,350 (AI est.), a medical institution performing 100 surgeries annually could expect an annual cost reduction of ~$550K (AI est.) ($5,350 × 10% × 100 cases, with final figure rounded to nearest $50K). Additional benefits include reduced overall healthcare costs from shorter patient recovery periods and lower complication risks.
