MERGED TROCAR-OBTURATOR DEVICE FOR OPTICAL-ENTRY IN MINIMALLY INVASIVE SURGERY

The present invention provide for improved optical entry systems and methods for minimally invasive surgery. According to some aspects of the disclosure, an obturator and trocar are merged to provide a device that can be used with an integrated visualization means (e.g. laparoscope) to provide optical entry into a patient's body cavity. Further, a reconfigurable tip is configured to be in an entry state and a visualization state. Said aspects and associated method steps can significantly reduce the complexity of the entry process and do not require removal and reinsertion of surgical instruments which eliminates the need for valves in the trocar and reduces the possibility of contamination of the visualization means' objective lens.
