Computer-controlled surgical manipulation will be an important tool for neurosurgery, and preliminary experiments involving this robotic system demonstrate its promising maneuverability.

High-speed height measurement is required in industrial fields for analyzing the behavior of a breaking object, a vibrating object or a rotating object. A shape measurement performed using a phase-shifting method can measure the shape with high spatial resolution because the coordinates can be obtained pixel by pixel. A light-source-stepping method (LSSM) that uses a linear LED array by means of a whole-space tabulation method (WSTM) has been proposed. Accurate shape measurement can be performed using this method. The response speed of the LED array is greater than 12 kHz. In this paper, height measurement is performed using WSTM and LSSM with a linear LED array and a high-speed camera. It was verified that the response speed of the linear LED is greater than 200 kHz. The phase shifting was performed at 12 kHz, and the height measurement of the vibrating woofer was performed at 4 kHz using a 3-step phase-shifting method.

Abstract. In neurosurgery, surgeons have to perform precise manipulations with poor visibility due to the presence of blood or cerebrospinal fluid and it is particularly difficult to operate in the deep surgical field. The authors have developed a microsurgical system for neurosurgery in the deep surgical field that addresses these difficulties. The authors succeeded in suturing the carotid artery of a rat under a glass tube 120 [mm] in depth and 50 [mm] in diameter. In this paper, the authors propose the concept of robotic-assisted micro-neurosurgery. The design and the system are presented. Furthermore, the performance of the system and in-vivo experiments on rats are also reported.
