This disposable trocar for abdominal cavity operations has two working channels: one for the optical instrument (laparoscope) and one for the surgical instrument. This means that only one insertion into the skin is necessary, making the procedure less invasive. Moreover, the laparoscope does not have to be operated by a second person. The two instruments can be managed simultaneously with one hand, giving the surgeon direct control over the field of vision.

With its sophisticated design, this trocar innovatively synchronises the movements of the instruments required for a laparoscopy procedure.
