摘     要
 随着医疗技术水平的快速发展，对各类医疗器械的精度要求越来越来高。夹骨手术钳作为一种医疗器械，其技术水平的高低直接关系到手术的成败，关系病人的身体健康，所以说夹骨手术钳技术的研究至关重要。本文讲述了关于夹骨手术钳研发与设计。首先，依据设计目的和要求，查阅、收集现有资料，手绘手术钳的外形结构图简图；接着，运用CAD软件绘制出其各个零部件的详图；然后，通过计算进行强度校核；再者，依据CAD图编制加工工艺；再使用UG软件画出三维图，进行装配和运动仿真。本夹骨手术钳的亮点是夹起直径在3-10mm的骨头后自锁，并保证骨头不会有损伤，两个中心轴，齿纹的设计和防滑凹槽设计。

Abstract
 With the rapid development of medical technology level, the requirement towards the precision of various types of medical equipment becomes higher and higher. Bone-folder operating forceps. As a medical device, the level of its technology is directly related to the success of surgery ,and the patients' physical health relationship .So the study of technique of bone-folder operating forceps is essential. This paper describes the research and design of the bone-folder operating forceps. First of all, inspects and collects the available information according to the purpose and requirements. Paints surgical clamp shape structure chart diagrams by hand. Secondly, I use cad software to map out its various detailing parts.Then I check the strength calculation; fomulates processing technique according to CAD Diagram. I use UG software to draw three-dimensional map, assembly and motion simulation. This clip highlights of bone-folder operating forceps is the self-locking after pinching the diameter 3-10mm bones. For ensures no damage to bones, the two central axis, the tooth design and anti-slip groove pattern design.
