Abstract
A flexible needle guide for needle aspiration during gynecological examination is described. In 1955 Franzen introduced a special technique for cytological diagnosis of prostatic tumours by transrectal needle aspiration biopsy and he has published several articles about this technique of biopsy from palpable tumours in various organs, such as the thyroid gland, breast, liver, salivary gland and other tissues that can be reached with a needle.
