ABSTRACT:
A hollow surgical disposable needle of the Redon type and posteriorly surrounding and retaining a tube-shaped drain manufactured in one piece of a strip of stainless steel. This strip is bent into pipe-shape and pressed together at its front end in such a manner that the compressed part of the pipe comprises a cutting edge inclined relative to the longitudinal axis of the needle, whereas the pipe at its rear end comprises internal barbs securing the drain. In this manner an advantageous and very inexpensive Redon needle for disposable use is obtained.
