查询词典 screw

Plastic should lower 3 steps, because plastic is a step to add melt resin material to cyclinder , Higher stick of resin material ,higher screw back pressure. Screw speed differs depending on decomposing temperature of resin material ,Higher screw speed ,Higher trim force of resin, higher cyclinder temperature. Some resin material may decomposes so it set screw speed in mid-speed such as 45-75%, In plastic step setting screw back pressure is very important, Higher screw back pressure ,higher quality of product screw back pressure make resin structure order, Molding product is beautiful and volume stable.

再复杂的熔胶旋转过程最多不会超过三段，因为熔胶本身就是存在于把胶熔进料筒的过程，如果原料粘度大，熔胶压力则大，但速度则应取决于原料的分解温度，熔胶速度越快，原料中的剪切力则会越大，料管温度则越高，局部原料产生分解的可能性则会越大，故一般熔胶会采用中速为宜，如45%-75%，熔胶同时会碰到一个比较重要的环节，那就是背压的使用，产品精度要求越大，背压的使用则更大，背压可使原料分子间结构更紧密，成型出的产品则尺寸更稳定，外观越好。

Six cadavers were prepared for necroscopy, operative procedure of ILIF were simulated on L3-S1, and all related important anatomic structure and their relationship were observed and record. ILIF with transpedicle screw fixation were also performed with cage insertion.3. Twelve fresh frozen bovine lumbar functional spinal units were prepared for biomechanical testing. According to the different treatment order, the specimens were devided into 7 groups, which included: 1intact specimens, 2specimens were treated by left unilateral facetectomy and had homolateral anatomical threaded cages inserted, 3 TLIF with homolateral pedicle screw fixation, 4 TLIF with bilateral pedicle screw fixation, 5 specimens had anatomical threaded cages inserted on the left by intertransverse process approach, 6 ILIF with homolateral pedicle screw fixation, 7 ILIF with bilateral pedicle screw fixation.

方法1、对20名正常志愿者L3-S1节段进行CT增强+三维重建检查，在三维重建图形上测量横突长度、上下横突间距、椎间孔外椎间隙高度及斜径，观查横突间区域血管走形特点并测量血管内径，然后进行统计分析及评价。2、采用福尔马林固定尸体标本六具，模拟ILIF手术对L3-S1节段进行操作，观察横突间区域重要结构的位置和毗邻关系，并模拟同侧椎弓根钉和单枚椎间融合器的置入过程，探讨该术式存在的问题并改进。3、采用小牛脊柱运动节段标本12具，依序进行不同处理后分为以下7组：⑴正常对照组CG⑵左侧小关节切除+椎间融合器植入组(TLIF⑶TLIF附加同侧椎弓根钉固定组；⑷TLIF附加双侧椎弓根钉固定组；⑸左侧横突间入路椎间融合器植入组ILIF⑹ILIF附加同侧椎弓根钉固定组；⑺ILIF附加双侧椎弓根钉固定组。

From 2004 to 2007, 34 cases were treated with extrapedicular screw fixation in Department of Orthopaedics, Third Affiliated Hospital of Sun Yat-sen University. The screw entry point, angle, depth and diameter were measured and defined on the thoracic vertebrae pedicle by CT thin-slice scan in standard prone for all cases before operation. The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement.
