本实用新型属于医疗器械领域，具体地说涉及一种本申请涉及一种防移位食管支架器械包。The utility model belongs to the field of medical equipment, and in particular relates to a displacement-proof esophageal stent device package.
背景技术Background technique
近年来，随着介入技术的越来越成熟，支架种类也越来越多，其中，食管支架对治疗食管狭窄、食管气管瘘等食管类疾病的应用也逐渐形成了主流，并取得了显著效果。食管支架在治疗此类疾病中有创伤小、效果迅速和安全简便的优点，特别是对于身体条件差，病程时间长的病人更显优势，是其它治疗手段难以替代的有效治疗方法。In recent years, with the maturity of interventional technology, there are more and more types of stents. Among them, the application of esophageal stents in the treatment of esophageal stenosis, esophageal tracheal fistula and other esophageal diseases has gradually become the mainstream and achieved remarkable results. . The esophageal stent has the advantages of less trauma, quick effect, safety and convenience in the treatment of such diseases, especially for patients with poor physical conditions and a long course of disease. It is an effective treatment method that cannot be replaced by other treatment methods.
食管支架根据覆膜情况可分为：无覆膜、部分覆膜和全覆膜。但不管植入的是哪一种支架，都有支架移位和脱落的风险。为了防止这种风险的发生，有两种方法：一是人们从产品结构上做出的改进如：ZL99230617.5脚刺型食管支架中提到的食管支架下端喇叭口处连接数只向下的倒刺，倒刺方向在喇叭口顺延方向呈斜向外下状，这种支架虽然稳定性好，不易下滑，但是如果下滑可能会刺破血管，引起大出血，危及生命；再比如：申请号201220198703.6一种螺旋形可降解食管支架专利中涉及到的一种经特殊结构设计的螺旋形可降解食管支架，可有效解决支架在使用中易滑落的问题。但作为可降解支架，对其力学性能和降解性能有其比较高的要求，降解过快或支撑力不够都容易出现再狭窄，同时对于食管内腔道而言出现移位和脱落的风险也是常见问题，而且价格比金属类支架要高很多。二十医生在做此类手术后的为防止移位和脱落，则不断的对患者进行短周期复查，如一周，半个月等，在确定移位后将进行支架回收，以防止滑落到胃中。这个过程虽然能防止支架脱落，但让病人忍受着不断复查的痛苦，同时治疗成本也大大增加了。Esophageal stents can be classified according to the covering condition: no covering, partial covering and full covering. But no matter what kind of stent is implanted, there is a risk of stent displacement and falling off. In order to prevent this risk, there are two methods: one is that people make improvements in the product structure, such as: the bell mouth at the lower end of the esophageal stent mentioned in ZL99230617. Barbs, the direction of the barbs is obliquely downward in the direction of the bell mouth. Although this kind of bracket has good stability and is not easy to slide down, if it slides down, it may puncture blood vessels, cause massive bleeding, and endanger life; another example: application number 201220198703.6 A helical degradable esophageal stent with a special structural design involved in the patent of a helical degradable esophageal stent can effectively solve the problem that the stent is easy to slip during use. However, as a degradable stent, it has relatively high requirements on its mechanical properties and degradation performance. Restenosis is prone to occur if it degrades too fast or has insufficient supporting force. At the same time, the risk of displacement and loss of the esophageal lumen is also common. problem, and the price is much higher than metal brackets. In order to prevent displacement and falling off after performing such operations, the doctors will continue to conduct short-term review on the patient, such as one week, half a month, etc. After confirming the displacement, the stent will be recovered to prevent it from slipping into the stomach middle. Although this process can prevent the stent from falling off, it makes the patient endure the pain of constant reexamination, and at the same time, the cost of treatment is also greatly increased.
因此，现新型一种防移位食管支架器械包，此种食管支架可以有效的避免移位和脱落的风险，并使患者减少频繁复查的痛苦，同时降低治疗成本。Therefore, a new type of anti-displacement esophageal stent kit is presented. This esophageal stent can effectively avoid the risk of displacement and falling off, reduce the pain of frequent reexamination for patients, and reduce the cost of treatment at the same time.
