Operative elliptical probe for ultrasonic surgical instrument and method of its use |
摘要 |
An improved ultrasonic surgical aspirator for use in breaking up and removing tissue from an operative site recessed within a tissue body employs an elongated probe having an oval or elliptical cross section to more closely conform to and fit an incision in the tissue and to expose a wider area of tissue to ultrasonic vibrations as the operative tip of the probe is moved over the tissue. An improved method of performing a lensectomy on the human eye using the improved apparatus is also disclosed.
