枢

A large trunnion or trunnion support design ensures central positioning under the highest working pressure. The trunnion mounted ball permits ease of operation.

三片式阀体设计大枢轴或枢轴板设计确保在高压下正确的中心位置，固定球结构保证阀门良好的操作性能。

A drilling apparatus (10) for earth boring operations is of the type having cutter blades (17, 18) mounted on a support body (12, 72, 82) at the lower end of a drill string and includes a novel arrangement of fluid bore sections (15, 23, 23', 63, 64, 65', 92) for delivering fluid under pressure into fluid discharge passages (50, 52) in each of the blades and a bifurcated pivotal mounting portion (16, 74, 91) on the body which enables the bore sections to supply fluid to the cutter blades through a ball joint (22) on the pivotal axis.

一种用于地面钻孔操作的钻井设备(10)，在钻柱的下端具有安装在支撑体(12，72，82)上的切割刀片(17，18)，并包括流体孔部分(15，23，23′，63，64，65，65′，92)和该支撑体上的分叉的枢转安装部分(16，74，91)的新颖结构，该流体孔部分用于在压力作用下将流体供给到每个刀片的流体排放通道中，该安装部分使的该孔部分通过枢转轴线上的球接头(22)能够将流体供给供给到该切割刀片。

Objective:To report the primary result of a newly-designed screw-plate system for the treatment of atlantoaxial instability.

目的：初步报告后路寰枢椎侧块钉板固定植骨融合术治疗寰枢椎不稳定的近期疗效。

The diagnosis of dearticulation of atlantoepistrophic articulation mainly according to measure the ADI. The X-ray pictures and CT were important.

寰枢椎脱位主要通过测量寰枢椎间距离诊断，主要依靠X线平片和CT测量诊断。

Results Seven cases were basilar impression,nine cases were dearticulation of atlantoepistrophic articulation,and five caces were Chiari abnormity.In the X-ray pictures,it showed the abnormal form of the atlas and axis,it also showed the Chamberlain line, according to which we could diagnose the basilar impression.

结果 21例中，颅底凹陷为7例，寰枢椎脱位9例，Chiari畸形5例。X线平片主要表现为寰椎、枢椎形态构异常，并且能显示Chamberlain线，借此可作出颅底凹陷的诊断。

Methods A total of 15 cases were fixed and fused with lateral mass screw of atlas and vertebra dentata pedicle screw.

方法采用寰椎侧块螺钉与枢椎椎弓根螺钉技术对15例寰枢椎不稳的患者进行固定。

Objective To summary the results of fixation and fusion with lateral mass screw of atlas combined with vertebra dentata pedicle screw for treatment of atlantoaxial instability and discuss the corresponding therapy methods.

目的总结侧块螺钉与椎弓根螺钉技术治疗寰枢椎不稳的效果，探讨寰枢椎不稳的固定方法。

The MPR was used to measure the height and width of posterior arch in the point of vertebra artery overpass, the height of lateral mass benenththe posterior arch and the height and width ofC2 interarticular isthmus.

结果 寰椎椎动脉沟处后弓高度为4.54±1.17mm，椎动脉沟处后弓宽度为8.69±1.12mm，寰椎后弓下侧块高度为4.98±1.07mm，枢椎峡部高度6.95±2.24mm，枢椎峡部宽度6.75±1.39mm，男、女2组之间没有统计学差异。

The control includes a cam ring in a housing pivotally connected to a wall of the housing by a pivot.

该控制包括凸轮环，该凸轮环在外壳中通过枢轴而枢转地连接到该外壳的壁上。
