Abstract


The research projects aim is to design a new type of orthopedic medical surgical institutions , which can replace the current commonly used in orthopedic surgery bone drill , but also to make up for the deficiencies of existing micro- gas drilling , so that it can meet the requirements of a variety of orthopedic surgery . It is powered by compressed air source , small size, light weight, dexterity, in orthopedic surgery has important significance and application value. Apply principles of fluid mechanics and mechanics of orthopedic medical surgical institutions designed impeller blade shape , the use of access control body in fluid mechanics research methods , the establishment of the impeller chamber gas dynamics model , and its aerodynamic analysis of the deduced airflow impulse force of the blade and the drive torque is calculated relationship , and to determine the operation of part of the orthopedic medical structure parameters . Increasing the output power as much as possible under the premise of the impeller , blade chamber according to the size of the inlet to determine the optimal number of blades of the impeller . According to the impeller blades airflow impact area affected by the changes in the movement of the impeller process into four positions , each position were obtained when the driving torque is calculated and plotted using Matlab software driving torque of each position curve . Finally got the impeller drive torque in a cycle of variation , for in-depth analysis of the impeller drive torque stability provides a theoretical basis . Orthopedic surgery to the overall structure bodies designed body structure, water and gas connection head structure , using AutoCAD, Pro / E and other graphics software to draw the structure of each part , and the compressed air used in this body and the cooling water made certain requirements . Carried out on the structure of the nose innovative design , micro- gas drilling in existing institutions based on the increase of the support structure, the tool changer and injection devices. In particular tool changer with a bilaterally symmetrical three spring structure , easier loading and unloading of the tool , making it easy , fast and flexible way to achieve the drilling, grinding , cutting multifunction operation. The overall structure of the impeller shaft design , draw overall configuration diagram of the impeller shaft .
