Medical surgical robot is a multidisciplinary field, involving robotics, telecommunications, image processing, virtual reality, Xi planing operation, and many injuries content. In the secondary brain surgery, the surgical robot Because of the high accuracy, repeatability, safety and other advantages, have become a hot research the international medical community. However, due to its advanced technology and cooperation in complex, the world only a few countries to work on the clinical application of 313.2 to the traditional means of stereotactic surgery for the head frame, to complete localization and puncture. Stereotactic frame on the one hand to ensure the stability and accuracy of positioning, it also limits the flexibility of operation and visibility. Although the foreign medical robot technology has been studied for many years, but have not yet achieved frameless stereotactic surgery. ... The group made the robot design and applications (CRAs-BH-type) system, 32 cases of successful surgical frameless stereotactic surgery, made a breakthrough in the field. * 53.3 .3 This principle is based on the role of the robot cr / MRI scan a three-dimensional medical image coordinate system, the brain stereotactic surgery Ge 6 and virtual operating rules, and finally multi-sensor positioning and operation of the auxiliary arm [ ,],[The group of frameless stereotactic surgery for a wide range of applications, the effect is better. Clinical practice shows that the robot system can improve the positioning accuracy and visualization operations to facilitate the operation the surgeon and to reduce surgical trauma, thereby strengthening the security and flexibility of operation. As frameless stereotactic surgery patients do not have to install the framework of the head, in reducing pain in patients with surgery, but also reduce their psychological burden. 3.4 Comparison with foreign robot system, the machine has the following main characteristics [s-7]: ① scan positioning device: for a large number of CT, MRI features of models to design the software can be obtained through a variety of scanners specifications or IvIRI CT image data. ② simple mapping method: Application of the cursor on the computer screen, select the intended target directly. And automatically by coordinate transformation to map coordinates to the point of intelligence arm. ③ planning surgical approach: the use of PC, display real-time simulation technique to choose the needle path, the surgeon determine the target navigation. ④ operating device platforms: the end of multi-joint intelligence arm coordinate not only the role of target instructions can also be loaded needle, endoscope and other instruments; patients who choose to avoid the major functional areas of the brain after the needle track. Xi motors to maintain the stability of a fixed arm posture, pointing devices such as the probe target, the actual positioning accuracy of 1.5mm. The main objective of micro-trauma to the modern stereotactic neurosurgery, is moving fine, the program direction. Frameless stereotactic surgery represents this trend, has very broad applications.</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/xeon/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
