Abstract
Abstract A method and means for biopsy of the prostate gland utilizing cytologic studies as a basic for presumptive diagnosis. A biopsy needle is passed through a guide which may be fixed to the operator''s gloved finger by a ring member. After the guide is placed on the finger, a finger cot is applied over the apparatus and finger for sterility and to facilitate insertion of the guide and finger internally of the body. The needle is then inserted through the guide and into the substance of the prostate. A syringe is attached to the needle and utilized for withdrawing a tissue sample whereupon slides are prepared for diagnosis of prostatic malignancy.
