In order to understand the specific position of the shunt release during the insertion process, it can be in the middle axis.
4上设置有刻度 15，通过判断滑动部 5在中轴 4上滑行过的相对位置， 掌握分流管的释放进度。 4 is provided with a scale 15. By judging the relative position of the sliding portion 5 on the middle shaft 4, the release progress of the shunt tube is grasped.
增厚部 12限制滑动部前管 9进入脊髓的深度，增厚部 12的前端 对应于以对合状态安装于滑动部前管 9内的分流管中心管的中后部， 以便分流管两端的上、 下支撑部的自由撑开。 工业实用性 The thickening portion 12 limits the depth of the sliding portion front tube 9 into the spinal cord, and the front end of the thickening portion 12 corresponds to the middle and rear portions of the shunt tube center tube that is attached to the sliding portion front tube 9 in the mating state, so that the ends of the shunt tube are The free support of the upper and lower support parts. Industrial applicability
本发明的植入性分流管， 由于在分流管的两端分别设置有上、 下 支撑部， 上、 下支撑部为对应设置的两个半管或管， 在安装的时候， 将上、 下两个半管或管对合起来， 这时， 上、 下两个支撑部形成宽度 与中心管直径相同的直形延伸， 在配套置入器的配合下， 可以方便的 将该分流管置入需要分流的脊髓空洞或髓内嚢肿的腔内和蛛网膜下 腔内， 而在分流管进入脊髓空洞或髓内嚢肿的腔内和蛛网膜下腔内 后， 分流管呈现原始状态， 支撑部可以支撑在脊髓空洞或髓内嚢肿的 腔内和蛛网膜下腔内，起到定位和固定的作用， 从而保证分流管不会 脱离。 与植入性分流管配合使用的配套置入器， 可以方便的配合将分 流管准确的放置于分流部位， 分流管与配套置入器的配合使用， 克服 了过去手术创伤大、 分流管固定困难、 操作繁瑣的问题， 使患者愈后 效果更好。 The implantable shunt tube of the present invention has upper and lower support portions respectively disposed at two ends of the shunt tube, and the upper and lower support portions are correspondingly disposed two half tubes or tubes, and are installed up and down The two half tubes or tube pairs are combined. At this time, the upper and lower support portions form a straight extension having the same width as the diameter of the center tube, and the shunt tube can be conveniently placed under the cooperation of the matching inserter. Need to divert the syringomyelia or intramedullary edema in the lumen and subarachnoid space, and after the shunt into the syringomyelia or intramedullary edema cavity and subarachnoid space, the shunt tube assumes the original state, support The part can be supported in the stomata or intramedullary edema and in the subarachnoid space to locate and fix, so as to ensure that the shunt tube does not detach. The matching inserter used with the implantable shunt tube can conveniently fit the shunt tube accurately to the shunting part, and the shunt tube and the matching inserter can be used together to overcome the difficulty of the surgical trauma and the fixing of the shunt tube in the past. The cumbersome operation of the problem makes the patient better and better.
