The anatomic femoral attachment site of the FCL, slightly proximal and posterior to the lateral epicondyle, 20 was isolated, and an eyelet pin was drilled proximomedially across the distal femur through the center of the FCL femoral attachment site. A 7-mm reamer was then reamed to a depth of 25 mm over the eyelet pin, and a 7-mm bioabsorbable screw tap was used to tap the tunnel.

FCL在股骨外上髁后侧稍靠近端的解剖学附着点[20]离断，通过股骨FCL附着点的中心穿过股骨远端在靠内侧用小针钻孔，然后用7mm扩孔钻顺小钉扩至深度为25mm，使用7mm可吸收螺钉攻丝形成隧道。

This kind of wells couldn"t be repaired with present technical, or the repair costs are too high so they should be abandoned. But indeed the reservoir underground also has developing value. By side-tracking technical, we can use original well site, needn"t to land lease and relay ground pipeline, also a segment of original wellbore can be used and no new well needed. So the repair speed expedites, ensures the stabilization of productivity. At the same time it can supply new work-over technical for oilfield which can server for oilfield all over the world.

采用侧斜工艺技术进行修复可以利用原井场，不用重新征地，不需重新铺设地面管线，可以利用一段原井眼，不影响原来的井网布置和开发方案，不需再钻更新井，恢复原有的注采关系，修复速度也将大为提高，保证了油田稳产，同时在技术上为油田提供新的修井手段，利用此项技术可以为国内外其他油田服务。

Methods Twenty-two pieces of temporal bone were taken for this study. The mastoid cavity was opened, scutum removed,"bridge" broken down, posterior wall of external auditory canal abraded and the related anatomic structures were fully exposed. The distance between the origin of facial nerve canal and the anterior border of round window （ OOFNC-ABORW ）, between the highest point of the facial nerve canal and the bottom of posterior mastoid sinus,and between the stapes head and round window niche was measured under operating microscope.

方法取成人颞骨22侧（左右各11侧），用耳科钻磨开乳突腔，去上鼓室盾板、断"桥"，磨低骨性外耳道后壁，充分暴露相关结构，在手术显微镜下测量面神经管垂直段起始部前缘至圆窗龛前缘的距离、面神经管最高点与后鼓室底壁之间的距离、锥隆起的高度（即锥隆起基底到锥隆起顶端的距离）、镫骨头至圆窗龛前缘的距离。

Methods Seventy eyes of sixty seven patients were divided into two groups randomly according to the incision location; Group A comprised 34 eyes which had surgery using superior approach, Group B comprised 36 eyes which had surgery using the superolateral apporach.

对67例（70只眼）白内障患者根据切口位置随机分成两组，A组：上方切口组34只眼，B组：颞上侧或鼻上侧切口组36只眼，用钻石刀在角巩膜缘后0.5mm做隧道长1.75mm阶梯形切口行白内障超声乳化摘除人工晶体植入术。

ABSTRACT Drilling time will be lasted and lateral force on casing exerted by drill pipe will increase in case of drilling deep well, ultradeep well, high inclined hole, extended reach well and horizontal well, therefore, friction and wear between casing and drill pipe became a severe problem.

在深井、超深井、大斜度井、大位移井及水平井中，钻井时间延长、钻柱作用在套管上的侧向力增高，因此套管和钻柱的摩擦与磨损问题越来越突出。

Soft tissue shaving cannulas and new bone-cutting drills are potentially less traumatic and also more precise tools for soft tissue extraction and bone removal.

骨头切割钻磨器的骨干被外套所保护，不会伤害到钻磨对侧的组织。抽吸器附在外套内，可及时抽吸骨屑，提供一个清晰的手术视野。

Drills in the median line with the small crack marks the good median line position, The horizontal osteotomy is then completed with a saw, and removal of midline wedge of bone from a lingual approach.

在中线用小裂钻标记好中线位置，在左右下牙6到6之间截骨，截骨完成后，再于颏部中央截取底边在舌侧的等腰三角形骨块，将颏部骨块内旋，在唇侧表面以微型钛板固定。

Be living in the deep well ultradeep well prospecting process ,Since radial direction force 、Eddy is stird 、Elements such as horizontal vibration and so on being ,In the wake of well drilling time the increase ,The auger post writings is used the casing inside wall crossrange strenuously to broaden ,It is more and more grave to cause casing and drilling rig to join the wornout problem .

论文摘要：在深井超深井勘探过程中，由于径向力、涡动、横向振动等因素的存在，随着钻井时间的增长，钻柱作用于套管内壁的侧向力增大，导致套管和钻具接头磨损的问题越来越严重。造成钻具耐磨带失效的主要原因有地层研磨性、钻杆的井下工况、耐磨材料选择与
