Abstract-This paper presents a silicone retractor, which is a continuation and extension of a previously developed system that had the same three functions as the old version: 1) retracting, 2) suction, and 3) force sensing. These features make the retractor a safe choice for use in neurosurgery. Suction is achieved by attaching the retractor to a suction pipe. The retractor has a deformation area filled with an incompressible liquid that is displaced in proportion to the extent of deformation; fiberscopes or human eyes detecting the displacement get a visual representation of the force. The new design improves on the old one in three ways-miniaturization, made possible by the incompressible-liquid-based mechanism, and measurement of force distribution by distribution of the areas deformed by force. The system was validated by conducting experiments.

“…Sensors utilizing force visualization have been developed, although their intended applications are not medical. Ohka et al [12] have developed a three-axis force sensor by observing the states of conical feelers with a camera. Kamiyama et al [13] have developed a sensor that measures the direction, magnitude, and distribution of force by observing two layers of spherical markers with a camera.…”

Abstract-This paper presents a novel force sensing system for fiberscopes. The key features of the system are its low cost, high resolution, small size, and ability to measure threedimensional force. A previous study described a novel force sensing system that could be attached to a very thin fiberscope, based on a force visualization mechanism utilizing panty stocking fabric-a highly elastic material. However, this system measures force in only one direction. In this paper, the system is extended to measure forces in any of three directions. The system is targeted for application to neurosurgical examinations. It may also be useful for other medical and non-medical examinations that involve the use of fiberscopes.

“…K. Kamiyama et al estimated a three-axis contact force by detecting the sensor body's deformation, using a two-layered dotted pattern and a charge-coupled device (CCD) camera [16,17]. The sensor reported in [18,19] consists of rubber sheets with nubs, a transparent acrylic plate, a light source and a CCD camera. Light travels through the transparent plate and is diffusely reflected where the nubs come in contact with the plate.…”

This paper presents a new approach for estimating contact force and slippage by using a vision-based tactile sensor with a fluid-type touchpad for the dexterous handling of robots. The sensor consists of a CCD camera, LED lights, a transparent acrylic plate and a deformable touchpad. The sensor can obtain a variety of tactile information, such as the contact force, shape, contact region, position and orientation of an object in contact with the fluid-type touchpad. The previous method for measuring contact force requires extensive calculation; this paper proposes a new method based on lookup tables for measuring normal force, tangential force and moment, using a fluid-type touchpad. Additionally, we clarify the mechanism of slippage between a fluid-type touchpad and a contacted object. This mechanism is efficient for applying the proposed slippage estimation method to a fluid-type touchpad. The validation of the proposed methods is confirmed in the experimental results.
