ABSTRACT:
An insufflation needle having a viewing system at its distal end and a trocar, both of which can be inserted through rotation of the puncturing element of the instrument, and a method of using these instruments. Both the insufflation needle and the trocar include a rotatable puncturing mechanism and a safety shield which allow the instruments to be safely inserted into body tissue through the use of a drill thereby requiring less force and reducing the possibility of trauma to the patient. The insufflation needle also includes a viewing system which allows the surgeon to view the distal end of the needle while it is being inserted into body tissue as well as to view the distal end of the trocar once it reaches a destination within the abdominal cavity proximate the distal end of the needle. The system reduces the risk of improper placement of both the needle and the trocar to thereby result in a safe laparoscopic surgical procedure.
