摘要：【中文】本发明涉及CT定位辅助用具技术领域，具体为一种新型CT定位穿刺空间引导器，包括一对角立柱，一对角立柱之间设置有可转动的纵向角度器和横向角度器，纵向角度器呈半圆环结构且侧面内边缘处等角度设有若干角度线，横向角度器的侧面拐角处开设有方槽，方槽的内部卡接有水泡仪，横向角度器的侧面设置有穿刺针，穿刺针的尾端设有方形的针座，针座的外侧套设有引导套。本发明通过将角立柱移动至患者身体上方，调节角立柱高度和横、纵角度器固定杆的水平位置以及角立柱万向轮的水平位移，对准预定穿刺点。从而明确穿刺进针点与进针空间路径。再通过按压针座观察其外露的刻度线，确进针深度。 【EN】The invention relates to the technical field of CT positioning auxiliary tools, in particular to a novel CT positioning puncture space guider which comprises a pair of corner stand columns, wherein a rotatable longitudinal angle device and a rotatable transverse angle device are arranged between the pair of corner stand columns, the longitudinal angle device is of a semicircular structure, a plurality of angle lines are arranged at the inner edge of the side face at equal angles, a square groove is formed in the corner of the side face of the transverse angle device, a bubble instrument is clamped in the square groove, a puncture needle is arranged on the side face of the transverse angle device, a square needle seat is arranged at the tail end of the puncture needle, and a guide sleeve is sleeved on the outer side of the. The invention aims at the preset puncture point by moving the corner upright post to the upper part of the body of a patient, adjusting the height of the corner upright post, the horizontal position of the fixing rod of the transverse and longitudinal angle device and the horizontal displacement of the universal wheel of the corner upright post. Thereby defining the puncture needle inserting point and the needle inserting space path. And then the exposed scale marks are observed by pressing the needle base, and the depth of the needle is determined.

摘要：【中文】一种联动制动轨道车辆止轮器，包括本体和联动制动装置，联动制动装置卡设在本体中，本体受压带动联动制动装置制动，所述联动制动装置包括承压组件，承压组件联动设有联动组件；承压组件受压纵向位移带动联动组件横向位移。本公开结构的设置，提高止轮器的稳定性和安全性，降低了操作难度，简化安装与拆卸过程，缩短工作时间。 【EN】A linkage braking railway vehicle wheel stopper comprises a body and a linkage braking device, wherein the linkage braking device is clamped in the body, the body is pressed to drive the linkage braking device to brake, the linkage braking device comprises a pressure bearing assembly, and the pressure bearing assembly is provided with a linkage assembly in a linkage manner; the pressure-bearing assembly is pressed to longitudinally displace to drive the linkage assembly to transversely displace. The setting of this disclosed structure improves the stability and the security of scotch block, has reduced the operation degree of difficulty, simplifies the installation and dismantles the process, shortens operating time.
