Injection applicator for tissue markers

The inventions provided herein relate to injection applicators, tissue markers and uses thereof, e.g., to mark a target tissue site (e.g., a biopsy site in a breast tissue) or to produce a cell scaffold. The tissue markers described herein are designed to be resistant to fast migration (e.g., immediate migration after implantation through a needle track) and slow migration (e.g., over an extended period of time) upon implantation at a target tissue site (e.g., a biopsy site in a breast tissue), without using an adhesive. Additionally or alternatively, the tissue markers described herein can be readily detectable by at least one imaging modality, e.g., but not limited to magnetic resonance imaging, X-ray imaging, ultrasound imaging, or a combination thereof.

Radiofrequency ablation device needle withdrawal system to avoid scarring

This application relates to the field of medical devices and discloses a needle withdrawal system for radiofrequency ablation devices that avoids scarring. Based on a standard radiofrequency ablation device, the system integrates a needle position detection device (real-time monitoring of depth and speed) and a needle tip temperature sensor. During needle withdrawal, the radiofrequency power is dynamically adjusted according to the withdrawal speed (higher power for faster speed); when the needle tip depth is less than a predetermined threshold (close to the body surface), the radiofrequency output is automatically stopped and a prompt to wait for cooling occurs; once the temperature drops below a safe threshold, a prompt indicates that the needle can be completely withdrawn. Through this closed-loop control, the thermal coagulation and end-point cooling processes of the needle track are precisely managed, effectively preventing thermal damage to the skin and subcutaneous tissue and significantly reducing scar formation.
