A retractor instrument for use in laparoscopic surgery, comprises an elongate frame or holder and a substantially rigid retractor member movably mounted to the frame. A first retainer component is mounted to frame for maintaining the retractor member in substantially parallel relation to the frame during an insertion of the retractor instrument through a patient's abdominal wall and partially into the patient's abdominal cavity in a laparoscopic procedure. A second retainer component is connected to the frame for maintaining the retractor member in an angled orientation with respect to the frame during utilization of the retractor instrument to displace an internal body organ of the patient in the laparoscopic procedure.
