A biopsy marker with real-time ultrasonographic visualization function and a preparation method thereof
By using biodegradable aliphatic polyester polymers and inorganic salt porogens to prepare porous scaffolds, and filling them with high acoustic impedance gas, the problems of poor ultrasound imaging and easy displacement of existing breast tissue markers are solved. This achieves strong and long-lasting ultrasound imaging and controllable degradation, is compatible with existing operating procedures, and ensures patient safety.

AI Technical Summary
Existing breast tissue markers are not well visualized under ultrasound, are prone to displacement, have short visualization time, and cannot be degraded. Metal clips pose a risk of foreign body retention, affecting patient health and imaging examinations.
Biodegradable aliphatic polyester polymer materials are used to prepare biopsy markers. A porous scaffold is formed by an inorganic salt porogen, which is then filled with a high acoustic impedance gas to form a stable gas-liquid interface to enhance ultrasound imaging. The markers are then completely degraded in vivo.
It achieves strong and long-lasting imaging effect under ultrasound, with precise positioning, avoids the risk of foreign body retention, has good biocompatibility and safety, is compatible with existing operating procedures, and has a controllable degradation cycle.
