An insufflation needle apparatus which creates a pneumoperitoneum during the preparation of a patient for endoscopic surgical procedures is disclosed. The insufflation needle apparatus is characterized by a helical needle having a central helical passageway for gas therethrough. The helical needle is associated with a guide support member which maintains the helical needle in position for insertion into a patient while at the same time permitting free rotation of the helical needle about the central longitudinal axis of the support member independent of movement of the support member. In this manner, an upward traction force can be exerted on the support member to gently pull the wall of a patient's body cavity upwardly away from vulnerable internal organs while at the same time a downward force can be exerted on the helical needle while it is rotated in order to penetrate the peritoneum with the needle. The invention results in a safer method for gas insufflation and creation of a pneumoperitoneum during the preparation of patients for endoscopic surgical procedures.
