Abstract

A flexible and steerable aspiration tip (10) for microsurgery includes a distal tip (9). The configuration of which may be remotely altered to access different areas at a surgical site. The aspiration tip (10) includes a flexible portion (3) which includes a spring material (5) therewith which may be configured in a relaxed and precurved state or, alternatively, a stressed and straight configuration. The aspiration tip (10) may be combined with a handpiece assembly (30) which includes a means (57) to remotely alter the configuration of the aspiration tip (10). Different surgical procedures performed with a single flexible and steerable aspi-ration tip which results in a reduction of trauma and stress to the surgical site by eliminating the use of several surgical instru-ments and complicated surgical techniques.
