Endo-Periscope II – Smart Ring-Spring Steering

Developed in 2001-2002, diameter 12 mm, steering range: ±125º in all directions.

The Endo-Periscope II has been developed in cooperation with Prof. Shigeo Hirose of the Hirose & Fukushima Laboratory, Tokyo Institute of Technology.

Endo-Periscope II is a simplified, patented version of Endo-Periscope I containing two enhanced compliant Ring Springs to control both left/right and up/down tip rotations. Endo-Periscope II contains an improved spatial parallelogram-mechanism that minimizes bending radius in all positions of the tip. A prominent part of the mechanism is a compression spring in the handgrip that compensates the spring force of the two Ring-Springs.
