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.
An aspiration needle for use in collecting larger cell samples with a syringe for fine needle aspiration cytology without increasing the size of the needle comprising a rigid elongate tubular member having distal and proximal extremities, the distal extremity being formed to provide a sharp point, the tubular member having a bore extending therethrough from the distal extremity to the proximal extremity and having an opening at the distal extremity in communication with the bore and a body secured to the proximal extremity of the tubular member and forming a chamber therein in communication with and in close proximity to the opening to the bore of the tubular member, said chamber being formed by a sloping uninterrupted side wall leading distally to the opening to the bore of the tubular member, said body including a hub separate from the chamber and spaced proximally of the chamber for receiving said syringe and for establishing communication between the syringe and the chamber.
