Abstract
An aspiration needle for use with a syringe for fine needle aspiration cytology comprising a rigid elongate tubular member having distal and proximal extremities. The distal extremity is formed to provide a sharp point. The tubular member has a bore extending therethrough from the distal extremity to the proximal extremity. A body is secured to the proximal extremity of the tubular member and forms a chamber therein in communication with the bore of the tubular member. The chamber is formed by a sloping uninterrupted side wall leading to the bore of the tubular member. The body includes a fitting for receiving the syringe and for establishing communication between the syringe and the chamber.
