| Summary: | 碩士 === 國立中央大學 === 生物醫學工程研究所 === 97 === The lone-term clinical curative effect of the hip joint replacement has still been clinician and the joint prosthesis designer matter of concern. The number of quantity of the bone tissue excision and the stability after the operation both are the important consideration factors to influence the curative effect after the operation. Relatively, the joint resurfacing surgery excises the bone quantities are few, can therefore retain the natural joint anatomy property as far as possible, and the surgery will not chanfe joint’s stress situation largely. On the other hand, it may also reduce the anaesthesia time with to reduce the opportunity which the blood transfusion and the instrument infect, causes the second surgery success ratio to enhance largely. Simultaneously the surgery has the surgery characteristic that does not need to bail the well dry the medullary cavity of bones, is also suitable for the applications of the minimally incision surgery. Therefore, the joint resurfacing surgery in abroad has became the treatment way for only joint surface tissue necrosis or the degenerated again at present.
We can subdivide the joint resurfacing surgery that has the kind of the minimally bone excision quantity characteristic into total and partial two patterns. The total joint resurfacing surgery will excise the necrotic tissues on the joint head surface entirely; will then put the implant with standard size to fix on articular surface in the paring type.Therefore the curved surface and patient’s joint surface are unable to fit completely. This research is directed against the design’s fedects on the clinical hip resurfacing today, and considers the surface’s differences between the femoral head joint degenerated position, then combines the technology of the medical image reconstruction technology. According to different patient, constructs the customization joint surface design, as well as corresponds the surgery instrument. Plan to estimate its whole feasivility in simulation, and constructs the finite element analysis platform when the hip joint stande, ues to improve the design of the resurfacing artificial hip joint.
According to the operation procedures of planning, in addition, prototypes and revises the designs of implants and instruments, the achievement has feasibility at present. And then verify that the design of this thesis is really more effectual than the artificial joint prosthesis while using via the result of the finite element analysis.
