A new insufflation needle with a special optical system for use in laparoscopic procedures.

A new insufflation needle with a special optical system consisting of a transparent, conical tip, to which an endoscope can be attached, allows perforation of the abdominal wall under direct vision. A video camera can be attached to the instrument, so that its progress through the abdominal wall can be observed on a monitor. The danger of damage to vessels and intra-abdominal organs associated with blind insertion of the insufflation needle is thus avoided.
