Description

一种磁性双J管及拔管器 一种磁性双J管及拔管器
技术领域
本发明涉及医疗器械领域，具体涉及一种磁性双J管及拔管器。
背景技术
双J管 （输尿管支架管）因具有支撑及引流的双重作用，在国内各医院均得到广泛应用。许多医院在泌尿系手术时常规放置双J管取代过去的经腹壁输尿管或肾盂造瘘，因为后者可能导致造瘘口渗尿、输尿管弯曲成角或狭窄等并发症。此外，双J管放置时间可长可短，病人可以先出院，以后在门诊可通过膀胱内窥镜拔管。
但是取出 双J管时需要使用 膀胱内窥镜，而膀胱内窥镜是刚性器械，检查及拔管会增加患者的痛苦和麻烦，增加尿道及膀胱损伤和感染的机会。另外，到手术室局麻拔除双J管加上消炎等治疗，需要费用近千元，给患者加重了经济负担。
如中国专利（授权公告号CN201768250U）所公开的免内镜取管的双J管，其在双J管上的侧孔内侧设有缠绕在双J管上的丝线，丝线的一头系于双J管上，丝线上敷有缓释薄膜；当双J管置于膀胱后，缓释薄膜可溶解，其丝线线头露出尿道口，通过牵引线头可将双J管取出。但是这种免内镜取管的双J管的结构虽然简单，操作方便，但是 拔管会增加患者的痛苦，不利于广泛使用。
发明内容
本发明解决的技术问题是提供一种磁性双J管及拔管器，其结构简便、安全可靠，经济实惠，可免除内镜取管。
为解决上述技术问题，本发明采用的技术方案是：一种磁性双J管及拔管器 ，包括双J管和拔管器，其中，所述的双J管端部设有磁铁圈或金属块或磁块；所述的拔管器包括拔管器软管和用于与磁铁圈或金属块磁性配合的磁铁，所述的磁铁设于拔管器软管的端部。
当拔管器软管进入膀胱，磁铁便可吸住双J管端部的磁铁圈或金属块或磁块，从而把双J管拉出，通过 双J管及拔管器的配合， 免除患者用内窥镜取管的痛苦和麻烦，免除麻醉手术的时间和费用。
进一步的， 所述的 磁铁圈或金属块内嵌于双J管端部的管体上。磁铁圈或金属块整个包覆于双J管端部的管体内；或者是磁铁圈或金属块的一端伸进双J管端部的管体，另一端露出管体外。上述两者方式均可使得磁铁圈或金属块稳固的内嵌于双J管端部的管体上。拔管器软管容易找到双J管在膀胱内的位置，顺利的取出双J管， 免除患者用内窥镜取管。
进一步的， 所述的 双J管的管体外径为1mm－2mm，内径为0.5mm－1mm。再进一步的， 所述的 双J管的管体外径为1.5mm，内径为0.83mm。上述双J管的尺寸较为合适，可方便拔管器软管的寻找和吸出。
具体的，所述的 拔管器软管为实心软管或空心软管。实心软管或空心软管均可减少病人的痛苦。
进一步的， 所述的 拔管器软管的管体外径为5mm－6mm。再进一步的， 所述的 拔管器软管的管体外径为5.3mm。上述拔管器软管的尺寸可使拔管器软管略有余地的进入尿道，方便使用。
当所述的 拔管器软管为空心软管时，磁铁内嵌于拔管器软管端部的管体上。磁铁整个包覆于拔管器软管端部的管体内；或者是磁铁的一端伸进拔管器软管端部的管体，另一端露出管体外。上述两者方式均可使得磁铁稳固的内嵌于拔管器软管端部的管体上。
进一步的， 所述的 磁铁圈或磁铁为强力磁铁圈和强力磁铁，所述的磁铁圈或磁铁吸力至少大于100G。通过强力磁铁圈和磁铁或磁铁和金属块的配合，可克服输尿管及尿道的阻力，使得拔管器软管可快速寻找进一步吸出双J管，减少 患者的痛苦。
进一步的， 所述的 拔管器软管由软性硅胶材料制成。 进入膀胱拔管的软管由柔软的硅胶材料制成，可克服刚性镜体对尿道的刺激和损伤。
与现有技术相比，有益效果是：本发明的 双J管端部设有磁铁圈或金属块；所述的拔管器包括拔管器软管和用于与磁铁圈或金属块磁性配合的磁铁，所述的磁铁设于拔管器软管的端部。 其结构简便、安全可靠，经济实惠， 方便门诊操作，免除患者用内窥镜取管的痛苦和麻烦，免除麻醉手术的时间和费用。
