What This Patent Covers

This patent protects a simple yet effective detachable stopper for endoscopic tools, specifically limiting protrusion to prevent tissue damage. Its claims, though concise, precisely cover the core invention. The patent's allowance after successful amendments against prior art objections indicates strong inventiveness and low invalidation risk, ensuring robust protection.

Competitive White Space

This patent primarily covers a mechanical stopper for endoscopic tools. White space exists in developing integrated smart systems with AI-driven image recognition for automated depth control or haptic feedback mechanisms, which are not covered by these claims.

ROI Calculation Logic

Assuming a 20% reduction in endoscopic procedure complication rates, a hospital performing ~1,000 procedures annually, with an average complication-related cost of ~$850 (AI est.) per case, could achieve an annual cost reduction of ~1,000 cases × ~$850/case × 20% = ~$170,000 (AI est.).

Speed to Market
6× faster than in-house development
This technology features a simple physical stopper that can be retrofitted to existing endoscopic treatment tools, requiring no new complex electronic control systems or software development. Detailed structure and operating principles are established in the patent specification, with the fundamental technology already proven. This allows for rapid productization by largely bypassing concept validation and extensive safety evaluations, enabling licensees to significantly shorten time-to-market and accelerate business deployment.

Technical Feasibility
This technology involves a simple configuration where a detachable stopper is installed between the entry port of an existing endoscope system and the elongated treatment tool inserted into the body. The patent claims clearly describe a limiting mechanism that fixes to the proximal end of the tool and abuts the entry port. This allows for relatively easy integration without major modifications to existing endoscopes or tools. No new complex electronic control or software development is required, as the primary focus is on physical mechanism adjustment, indicating low technical hurdles.
Success Scenario
Upon adopting this technology, medical facilities could see a dramatic reduction in accidental tissue damage caused by excessive protrusion of endoscopic tools during procedures. This could enhance patient safety, with an estimated reduction of up to 30% in post-operative complication rates. Furthermore, the average time required for tool insertion could be shortened by 20%, potentially improving operating room utilization and enabling treatment for more patients.
