The Research And Innovation Design Of The Orthopaedics Medical Treatment Operation Mechanism

The research purpose of this dissertation wants to design a kind of new the orthopedics medical treatment operation mechanism that can replace currently the in common use bone in the orthopedics surgical operation drill, make up the shortage that the existing and tiny spirit drill again, make it be able to satisfy the request of various orthopedics surgical operation.It takes compressed air as a motive source, the physical volume is small, weight light, usage clever, have important research meaning in the orthopedics surgical operation and applied value.Make use of fluid mechanics principle and mechanics principle designed the shape of the impeller lamina of the orthopedics medical treatment operation mechanism, make use of to take a research method of control the body in the fluid mechanics, built up the aerodynamics model of the impeller cavity, and as to it's carried on aerodynamics analysis, deduce to the relation formula of the impulsion power and driving moment of the orthopedics medical treatment operation mechanism.Be enlarging possibly under the premise that impeller outputs power, basis on the size of the lamina cavity certain the best lamina amount. According to the variety of the impact area that the airflow to the impeller lamina, the sport process of the impeller was divided into four positions, the calculation formula of driving moment while getting each position respectively, and made use of Matlab software to draw each position the variety curve of driving moment.Finally got the impeller driving moment in a variety regulation in period, for thorough analysis research the impeller driving moment steady provided theory basis.Carried on a total structure design to the orthopedics medical treatment operation mechanism, designed mechanism body structure, the water-air connecting joint structure, make use of AutoCAD, Pro/E etc. painting the software drew each part of structure diagram, and to this mechanism usage of compressed air and cool water put forward a certain request.Carried on an innovation design to the mechanism head's structure, in the foundation of the existing and tiny gas drill, increased the sustentation structure, reamer tool replacing device and affusion device.Especially the reamer tool replaceing device to adopt both sides symmetry of The three-petal-reed structure, more easy to the reamer tool to load and unload, thus convenient, shortcut, neatly carried out to drill, whet, incise the operation of multi-function integral whole.Carried on a design to the whole structure of leaf's axle, drew the whole structure diagram of leaf's axle.
