英文要約Title: Research and Development Project on Intelligent Surgical Instruments (FY2008-FY2011) FY2010 Annual Repor
(1-2) The technique of sensing the residual cerebral tumor
We developed newly magnetic or optical sensor for residual brain tumor using magnetite enveloped by cationic liposome (MCL). We miniaturized it to integrate the endoscopic robotic surgical system and checked the signal/noise ratio under the working of endoscopic robotic surgical system, showing the same sensitivity as the in vitro study.
(2-1-2) Sub console
We developed a simulation system for endoscopic robot surgery based on 3D virtual surgiscope. The system screen consists of five views: virtual endoscopic view, outside view, and three MPR views. The cylindrical object displayed on virtual endoscopic views represents the suction tool. The position of the virtual endoscopic camera and the suction tool can be controlled by the gamepad. Also, this system provides a collision detection function and virtual suction function. Using this system, neurosurgeons perform the simulation of the robotic surgery. The neurosurgeons were able to perform surgical simulation of the endoscopic robot in the virtual space.
(3-2-1) Endoscope
In order to observe the residual tumor left at sided wall of surgical cavity following the tumor resection under the microscope, we developed the endoscope with two sided lens and straight one, which could provide the stereotactic side view and straight view. The image quality is equal to high vision’s one.
(3-2-2) Endoscope holder
We developed the device for mounting the endoscope jointed with operative tools to head holder system. The device was allowed to manipulate manually in the three directions and inclination within 30 degree. The pitching and rolling of the endoscope and attached devices tip was limited within 1mm during the working and moving of those ones.
(3-2-4) Intelligent bipolar
We studied the coagulation effect of the current bipolar system using the animal muscle tissue under some condition to enhance the coagulation power without being charred. We tested the charring and sticking effect of bipolar coagulator varying the tip shaping, the power of output unit. And also, the testing was done under dropping of water or not. It was important to lower temperature at coagulation and fine electrode tip in order to avoid charring.
(4-1) Manual for training
We prepared the training manual for intelligent robot assisted surgery, referring to the robotic surgery training guideline prepared in the government enterprise. In the guideline, the textbook for the basic course of the robotic surgery was first completed. The training manual was based on the textbook.
(5-2) Pre-clinical evaluation
We verified the evaluation basis of the trial device and system on the assumption of the neurosurgical operation for the resection of residual brain tumor in the deep brain following the microscopic operation.
