Rotary powered device for bone marrow aspiration and biopsy yields excellent specimens quickly and efficiently

Area of Science:

• Medical Devices
• Hematology
• Surgical Technology

Background:

• Bone marrow biopsy is a critical diagnostic procedure.
• Traditional manual techniques can be time-consuming and may cause patient discomfort.
• Advancements in medical technology aim to improve biopsy efficiency and sample quality.

Purpose of the Study:

• To evaluate the safety and efficacy of a new FDA-cleared, battery-powered bone marrow biopsy system.
• To compare the performance of the powered system with manual bone marrow biopsy techniques.
• To assess the procedural time and specimen quality obtained with the new device.

Main Methods:

• A pre-clinical evaluation was performed on anesthetized pigs.
• A clinical evaluation involved 16 hematology patients requiring bone marrow biopsy.
• Specimen quality, cellular artifact, thermal damage, complications, and procedural time were assessed.

Main Results:

• No cellular artifact or thermal damage was observed in samples from the swine model.
• The mean procedural time in patients was 38.5 +/- 13.94 seconds.
• The powered system demonstrated equivalent specimen quality to manual methods, with no reported complications.

Conclusions:

• The new battery-powered bone marrow biopsy system is safe and easy to use.
• The device significantly reduces procedural time compared to manual techniques.
• This powered system represents an effective advancement for bone marrow biopsy procedures.
