Functions and advantages of Disposable Endoscopic Hemoclip

Disposable Endoscopic Hemoclips are single-use medical devices designed for mechanical hemostasis during endoscopic procedures. Their core function is to achieve immediate bleeding control through physical occlusion of blood vessels or tissue defects, primarily indicated for gastrointestinal ulcer bleeding, post-polypectomy wound closure, and minor vascular leakage.

Structural Features & Mechanism:

1. Mechanical Occlusion Design

   • Elastic arms made of medical-grade metals (e.g., stainless steel or alloys) are delivered to target sites via an applicator through the endoscope's working channel.

   • Upon deployment, the arms generate persistent mechanical pressure to compress vessel stumps or tissue edges, creating physical closure.

2. Operational Adaptability

   • Rotatable clip heads allow 360° positioning adjustment for angled lesions;

   • Select variants feature repositioning capability, enabling relocation before final deployment.

3. Material Safety

   • Biocompatible coatings (e.g., PTFE) minimize tissue adhesion and friction damage;

   • Electrically inert construction ensures compatibility with electrosurgical equipment.

Clinical Advantages:

• Immediate Efficacy: >95% success rate in achieving instant hemostasis for vessels ≤3mm;

• Minimally Invasive: Eliminates laparotomy, reducing procedural complications;

• Absorbable Options: Certain types utilize bioabsorbable materials, undergoing complete degradation within 6-8 weeks post-deployment to avoid long-term foreign body retention.

Technological Evolution:

• Enhanced Visibility: Integrated radiopaque markers for post-procedural imaging tracking;

• Pressure Self-Regulation: Adaptive clamping force based on tissue thickness to reduce perforation risks;

• Magnetically Guided Navigation: Precise deep-tissue targeting via externally applied magnetic fields (experimental phase).
