| | Abstract | The missile trocar was developed for controllable entry force, smaller fascial defects and post-operative pain improvement. The trocar was composed of a fascial-dilating long-conical head and a handle. Accompanied with this trocar, the authors designed a rectus sheath-hooking instrument to promote negative intra-abdominal pressure during the trocar puncture. The hooking procedure allowed room air to pass through the central canal of the trocar and fill the space between the intestinal loops and the trocar tip. The abdominal access procedure succeeded in forty-five attempts in fresh cadavers. No second attempt was done. The trocar accessed into the peritoneal cavity at every attempt without intestinal penetration. The missile trocar may be an alternative device for establishment of the primary port. Its efficacy and safety still has to be proved. | | Language | eng | | Pub Type(s) | Journal Article
