摘要： An aspiration needle for use in collecting larger cell samples with a source of vacuum for fine needle aspiration cytology without increasing the size of the needle having a rigid elongate tubular member having distal and proximal extremities. The tubular member has a bore extending therethrough from the distal extremity to the proximal extremity and has an opening at the distal extremity in communication with the bore. A body is secured to the proximal extremity of the tubular member and forms a chamber therein in communication with and in close proximity to the opening into the bore of the tubular member. The chamber is formed by a sloping uninterrupted wall leading distally to the opening to the bore of the tubular member. The body includes a hub proximal of the chamber for receiving the source of vacuum and for establishing communication between the source of vacuum and the chamber. The body has an enlarged portion adjacent the proximal extremity of the tubular member permitting viewing of the chamber in the vicinity of the proximal extremity of the tubular member to facilitate observation of aspirate as it is collected in the chamber.
