112 micro medical robot development In recent years, the medical robot technology research and application development into the Show soon, micro medical robot is one of the most promising applications The field, according to the Japan Science and Technology Policy Research Institute predicts that by 2017 The medical field the use of micro-machines and robot surgery will exceed all of Half of medical surgery. Therefore, Japan has developed a "robot surgery Doctor "program and is developing in the human body through blood vessels, using Find and kill the cancerous cells in the ultra-micro-robot. The United States, Maryland • Laboratory of Johns Hopkin developed a "smart pill", the actual Are equipped with micro-silica on the thermometer and micro-circuit micro-detecting device, Ingestion in vivo could be the body's temperature information to the recorder. Sweden Scientists invented a punctuation mark in English such as the size of the robot, not COME movable capture single cells or bacteria, and then in the human body to carry out the Types of surgery. Many domestic scientific research institutes to carry out a major non-invasive micro - Medical robot research has yielded some results. Noninvasive medical machine Devices are mainly used in the body cavity Human diseases medical care, it can be reduced Light or eliminate the current clinical use on various types of endoscope, within the syringe, which Drug delivery devices, such as medical equipment to patients with serious and the pain does not fit Bitter. At University of Science and Technology of China National Natural Science Fund Developed based on piezoelectric ceramics driven many snake swimming abdominal section hand Operation of micro-surgery robot, the robot will be CCD camera system, surgical Intelligent control system equipment and installed separately at the end of micro-robot, Through the opening in the abdomen in patients with small mouth, into the abdominal cavity surgery. Its special Points are fast response, high accuracy and exercise, the scope of force and motion Large, each section can achieve two degrees of freedom on the direction of ± 60 ° range of Motion Czech and flexible movements, as shown in Figure 2 is the use of intra-abdominal surgical robot Surgery scenes [5]. Zhejiang University has also developed non-invasive medical The prototype micro-robot, the micro-robot to approach Progressive Suspension Into the body cavity (such as intestinal, esophagus), can be avoided on the human body cavity has Organize machine damage, run faster, speed control of Convenience. 113 special operations of the development of micro-robot In addition to the above mentioned micro-pipes and non-invasive micro-robot Medical robot, the scientists at home and abroad extensively carried out Special operation of micro-robot research. This micro-robot with Preparation of the corresponding sensors and operating devices, in military and civilian aspects Very good prospects for development. The United States national security laboratory produced on the history of the world The smallest robot, this robot weighs less than 28g, the volume for 411cm3, leg mechanism for belt transmission device, the robot can replace Lot of people go to complete dangerous jobs. . Navy invented a micro - Urban search and rescue robot, the robot in 2001, "9111" thing Pieces of the ruins of the World Trade Organization after the occurrence of the search and rescue at the scene to show their talents. Mitsubishi electric Subsidiary of Matsushita Research Institute Tokyo and Sumitomo United Electronics Company Institute System that only ant-sized micro-robot, the robot can enter Very small space environment to engage in repair work on both sides of the body has two Circular connector can be connected with other robot to complete some special Task.
