Tandem Motion Device Facilitates Laparoscopic Surgery

A novel tandem motion visualization device allows surgeons to control both a laparoscope and a hand instrument at the same time and with one hand.

The Fujifilm (Tokyo, Japan) Interlock Trocar allows a surgeon full dual motion control of both the Fujifilm ultra-slim "Chip on the Tip" HD video laparoscope, and a five mm hand instrument simultaneously through a unique built-in coupling mechanism. The device includes a minimally invasive surgical trocar with two tubes, allowing a 3.8 mm laparoscope and a standard five mm hand instrument to access to the abdominal cavity at the same time, including for insufflation. The design of the trocar allows the laparoscope to be in direct alignment with and to follow the hand instrument.


Image horizon is adjusted and maintained regardless of hand instrument positioning and orientation, with the Ultra-Slim video laparoscope system continuously delivering self-visualization control with exceptional image resolution, excellent color fidelity, and sharp display quality. Additional features include an integrated lens cleaning function using a saline flush and aspiration, which allows the lens to be cleaned without removing the scope from the trocar.

“The Fujifilm InterLock Trocar was designed to make performing surgeries easier and more efficient for surgeons, and less invasive for patients,” said Stephen Mariano, vice president and general manager of Fujifilm new development USA. “With just one small incision, surgeons now have the ability to manipulate simultaneously both a laparoscope and a hand instrument. No additional clinician is required to control visualization while a surgeon is operating.”

A trocar is a medical device made up of an obturator, a cannula, and a seal that is designed for placement through the abdomen during laparoscopic surgery. The trocar functions as a portal for the subsequent placement of other instruments, such as graspers, scissors, staplers, etc. Trocars also allow the escape of gas or fluid from organs within the body.
