[Experience with sonographically controlled fine-needle punctures with permanent visual control (author's transl)]

Area of Science:

• Medical Devices
• Interventional Radiology
• Minimally Invasive Surgery

Background:

• Fine-needle aspiration is a common diagnostic procedure.
• Current methods may have limitations in visual control and applicability to certain anatomical regions.
• The need for safe, repeatable, and versatile biopsy techniques persists.

Purpose of the Study:

• To introduce and evaluate a new biopsy device.
• To assess the safety and efficacy of the device for various anatomical locations.
• To explore the device's utility in specialized procedures like amniocentesis and combined imaging interventions.

Main Methods:

• Development of a novel fine-needle biopsy device.
• Performance of fine-needle punctures under continuous visual control.
• Application of the device for lesions in the abdomen, thoracic cage, cervical region, and extremities.
• Evaluation of the device in amniocentesis and combined sonographical and radiological interventions.

Main Results:

• The device facilitates safe and effective fine-needle punctures in diverse anatomical areas.
• Procedures are performed with continuous visual control, minimizing patient risk.
• The device demonstrated advantages in amniocentesis, particularly with low fluid volumes.
• Successful combination of sonographical and radiological interventions, such as for kidney procedures, was achieved.

Conclusions:

• The new biopsy device offers a safe, low-risk, and repeatable method for minimally invasive procedures.
• Its versatility extends to various anatomical sites and specialized applications like amniocentesis and combined imaging.
• Continuous visual control enhances procedural safety and efficacy.
