How to use the ENDOEYE FLEX Deflectable Videoscope

Coaxial setup means that the relationship of the axes from the surgeon to the monitor and from the laparoscope to the target overlap each other in as straight a line as possible. When this axial relationship is secure, hand-eye coordination is easily obtained. However, such an ideal trocar position is not always possible.

Para-axial setup refers to a misalignment of the two axes. Misalignment of up to about 60° will not make laparoscope operation difficult. However, a wider misalignment will reduce the laparoscope operator’s efficiency.

The ENDOEYE FLEX, when used to provide laparoscope angulation, enables the visual axis to be aligned with the line of sight along which the surgeon observes the screen. This successfully corrects the misalignment arising from positional relation between the trocar position and the operative field.

In extreme cases, the layout shown above will provide a satisfactory setup.

With the rigid laparoscope, the scope length sometimes makes it difficult to secure an adequate field of view. In such cases, the scope head and the hand holding the scope head can interfere with the surgeon’s hand instruments operation. To avoid this problem, the surgeon is forced to operate in an uncomfortable posture.

When the laparoscope is directed vertically, a much wider space can be secured for operation on the near side.

This technique would be very useful in laparoscopic-assisted colectomy (LAC) procedures.
Through adjustment of laparoscope angulation, observation is enabled even behind the mesenterium.
