N2 - This paper explores the benefits of vacuum assistance to 18 gauge needle biopsy. Current biopsy methods are inefficient or have a high rate of failure, causing the need for further painful insertions. A novel needle insertion device was developed to create the vacuum in the needle. Using multiple pneumatic cylinders, a vacuum is created inside the end-cut needle by retracting the trocar while inserting the needle. Calculations were done to determine the force caused by the vacuum. Experiments inserting the needle into porcine kidney have shown that the vacuum assistance increases cutting efficiency.
