Abstract
A force sensing device and monitoring system for use in medical procedures, featuring an air-based sensor to quantify force applied during insertion of a ureteral access sheath (UAS), catheter, or other medical instrument. The invention features a pneumatic syringe mechanism, wherein force is measured by compressing an occluded syringe, translating pressure changes into a measurable force output. Real-time feedback is provided via visual, tactile, or auditory indicators, signaling predefined force thresholds (e.g., 4 N, 6 N, and 8 N) to prevent excessive pressure and resultant tissue injury. The invention provides precise, cost-effective, and widely accessible force monitoring without reliance on electronics or Bluetooth® systems, in various surgical fields, including laparoscopy, robotic-assisted surgery, endoscopic procedures, and vascular catheterization, ensuring safe instrument deployment and minimizing complications. The sensor can be integrated into existing medical instruments via Luer-Lock or similar interface connections and may be disposable or reusable.
