Access instruments for video assisted surgery: combination of mini-invasivity and universality

The idea of operating through fewer surgical incisions and, therefore, with potentially better cosmesis, less postoperative pain and paraesthesia, is becoming increasingly more preferable. For these reasons, Video-assisted thoracic surgery (VATS) came into widespread use in the early 1990s. VATS’ instrumentation includes conventional thoracic or laparoscopic instruments such as a camera-linked fiber-optic scope of variable diameters.
