Description
Translated fromChinese技术领域technical field
本发明涉及医疗器械技术领域，具体为一种术后免缝合引流装置。The invention relates to the technical field of medical devices, in particular to a postoperative suture-free drainage device.
背景技术Background technique
临床应用引流系统引流体液、消化液、排泄物及脓液是外科的主要工作之一，外科引流是将人体组织间或体腔中积聚的上述液体导出体外，用以控制感染、促进创面愈合、减少术后并发症、减轻液体占位效应引起的不适症状。Clinical application Drainage system Drainage fluid, digestive juice, excrement and pus is one of the main tasks of surgery. Surgical drainage is to export the above-mentioned fluids accumulated between human tissues or body cavities out of the body to control infection, promote wound healing, and reduce surgical procedures. Post-complications and relieve discomfort caused by fluid mass effect.
随着微创技术的开展，腹腔镜下胆总管切开取石T型管引流术治疗肝胆管结石已经成为肝胆外科常规开展的术式，一般通过术后留置修剪后的T型管于胆管内并缝合胆管壁，创面再放置腹腔引流管协同引流，减少及预防术后并发症的发生。腹腔镜下缝合技术是该手术成功的关键点之一，对于部分患者胆管壁炎症较重，胆管壁厚达3mm以上的，腹腔镜下缝合更为困难，不缝合有非常高的术后胆漏可能性，而非常规缝合将导致多种术后近期、远期意外及并发症的发生，增加患者痛苦及住院的费用。术后在体壁两处带引流管给患者带来更多不便及痛苦，多引流管也增加了术后脱管的几率，即使引流管拔出后，放置引流管部位炎症瘢痕明显，患者术后恢复慢，远期来看造成引流部位皮肤不美观。With the development of minimally invasive techniques, laparoscopic choledocholithotomy and T-tube drainage for hepatolithiasis has become a routine operation in hepatobiliary surgery. The bile duct wall is sutured, and an abdominal drainage tube is placed on the wound surface to cooperate with drainage to reduce and prevent postoperative complications. Laparoscopic suturing technique is one of the key points for the success of this operation. For some patients with severe bile duct wall inflammation and a bile duct wall thickness of more than 3 mm, laparoscopic suturing is more difficult, and there is a very high postoperative bile leakage without suturing. The possibility of unconventional suturing will lead to a variety of short-term and long-term accidents and complications after surgery, increasing the pain of patients and the cost of hospitalization. Having drainage tubes at two places on the body wall after surgery brings more inconvenience and pain to the patient, and multiple drainage tubes also increase the probability of postoperative detachment. The recovery is slow, and in the long run, the skin of the drainage site will be unsightly.
综上所述，现有的胆管壁炎症较重的患者在进行手术之后需要进行插管引流，并且在手术之后需要在体壁两处带引流管，患者手术之后身上两处插管会相互影响，也会使患者的术后痛苦加倍，同时也会增加脱管的几率，另外在术后引流管发出之后，患者身上两处放置引流管的部位炎症瘢痕非常明显，造成患者手术后恢复期较长，两处引流疤痕，在远期来看造成引流部位皮肤不美观，并且在对胆管创口进行缝合的时候非常困难，手术难度非常高。To sum up, the existing patients with severe inflammation of the bile duct wall need to be intubated and drained after the operation, and they need to have two drainage tubes on the body wall after the operation. , it will also double the postoperative pain of the patient, and also increase the probability of detachment. In addition, after the postoperative drainage tube is issued, the inflammatory scars on the two places where the drainage tube is placed on the patient's body are very obvious, resulting in a longer recovery period for the patient after surgery. Long, two drainage scars, the skin of the drainage site will be unsightly in the long run, and it is very difficult to suture the bile duct wound, and the operation is very difficult.

请参阅图1-4，一种术后免缝合引流装置，包括引流主管2，引流主管2的一顿固定连接有接头1，引流主管2的另一端设置有S形管4和上支管6，引流主管2的内部设置有主引流腔12，主引流腔12与S形管4和上支管6相连通，上支管6的中部固定连接有伞状软翼5，引流主管2的侧面套接有梭形阻挡环10，梭形阻挡环10的外部包裹有方形网3，方形网3的材料为羧甲基纤维素网，梭形阻挡环10由生物可吸收性聚乙醇酸膜制成，梭形阻挡环10和方形网3的中部均开设有与引流主管2相适配的圆孔，引流主管2的内部设置有弹性支撑环9，弹性支撑环9有若干个，若干个弹性支撑环9在引流主管2的内部等间距分布，弹性支撑环9由弹性良好的金属或塑料制成，引流主管2的侧壁设置有弹性结构软胶膜13，弹性结构软胶膜13的内部开设有通道11，通道11的两端均贯穿引流主管2的侧壁，通道11的内部插接有附属管8，接头1的一端接有负压即机，附属管8的一端与大气相通，附属管8的外侧壁包裹有弹性软片，弹性软片与通道11的端口处形成配合密封结构，S形管4、上支管6和附属管8的侧面均开设有引流孔7，引流主管2、S形管4、上支管6和附属管8的内部均设置有加强线，伞状软翼5由弹性材料制成，S形管4上的引流孔7有若干个，若干个引流孔7在S形管4的两个弯曲处等间距分布，附属管8和上支管6尾端的引流孔7均有若干个，若干个引流孔7在附属管8和上支管6的侧面等间距分布，引流主管2的周径为18～22F，上支管6的周径为12～14F，S形管4和附属管8的周径均为6～8F。Please refer to Figures 1-4, a postoperative suture-free drainage device, including a drainage
在使用时，首先将附属管8插进通道11的内部，接头1与外部的负压机连通，附属管8可以与大气连通实现自然引流，也可以与负压相连实现负压引流，手术的时候使上支管6和S形管4均放置在胆管内部，在进行手术的时候将伞状软翼5折叠之后填塞到胆管的内部，与上支管6之间配合作为第一级结构，从而阻挡胆汁外流，向外牵拉的时候伞状软翼5能够聚拢；同时S形管4也位于胆管内部，设置在S形管4弯曲内侧的引流孔7便于引流消化液及胆汁，并且能够避免负压吸引时胆管壁贴紧引流孔7，避免了影响引流，此结构为第二级结构；将S形管4和上支管6都放入胆管内部之后，利用方形网3和梭形阻挡环10对胆管创口进行闭合，由于方形网3和梭形阻挡环10的中部都有与引流主管2相适配的孔，能够使引流主管2从胆管内部穿出，并且能够利用羧甲基纤维素网遇水形成凝胶的特性，在手术的时候将内层的聚乙醇酸膜粘连固定于胆管壁创口处，并封闭其与主引流管之间的空隙，不需要对胆管壁进行手动缝合，从而降低了手术难度，也减少了术后并发症的发生，此结构为第三级结构；将附属管8带有引流孔7的一端放在手术区域靠近引流主管2出入胆管处，利用引流孔7吸引术区渗液及突破第三级结构而溢出胆管的胆汁及其他消化液，避免胆汁及其他消化液进入体腔，在手术之后患者身体上只插有引流主管2，将附属管8代替了第二根管，从而减少患者的痛苦，减少脱管几率；由于附属管8的外部有软片，能够保证附属管8与通道11之间成为封闭结构，使引流主管2内外不相通，在附属管8拔出的时候弹性支撑环9能够将弹性结构软胶膜13撑起，使通道11处于封闭状态；在经过几个月之后引流主管2周围会形成成熟的瘘道，此时可以将引流主管2拔出，此时可吸收材料基本已自行降解吸收。When in use, first insert the
综上，该术后免缝合引流装置通过设置弹性结构软胶膜13，能够使附属管8插进引流主管2的内部进行引流，在手术之后患者身上只需插入一个引流主管2即可，能够有效的避免两根插管造成的诸多问题，减少了插管伤口数量，也能减少了患者的痛苦程度，同时降低了脱管的几率，由于患者身上只有一处插管，能够有效的缩短患者的恢复周期，在恢复之后也减少身上疤痕数量，通过设置方形网3，在手术时由于羧甲基纤维素网遇水形成凝胶，能够将内层聚乙醇酸膜粘连固定于胆管壁缺损处，并封闭其与主引流管之间的空隙，在手术的时候可以实现不缝合，降低手术难度，减少术后并发症的发生。To sum up, the post-operative suture-free drainage device can insert the
