Description
技术领域Technical Field
本发明涉及医疗器械技术领域，具体涉及一种肠道柔性吻合支架植入辅助装置。The present invention relates to the technical field of medical devices, and in particular to an intestinal flexible anastomotic stent implantation auxiliary device.
背景技术Background Art
消化道吻合口漏是肠肿瘤、肠梗阻等胃肠道疾病术后治疗中影响肠道组织愈合或修复的严重并发症。吻合口张力高、血供低或术后感染是导致吻合口难以愈合而引发吻合口漏发生的主要原因。针对这些问题，生物组织工程支架的植入被认为是解决肠道吻合口漏的新途径，同时，这一研究领域对于加强临床治疗、改善患者生活质量具有重要意义。Digestive tract anastomotic leakage is a serious complication that affects intestinal tissue healing or repair during postoperative treatment of gastrointestinal diseases such as intestinal tumors and intestinal obstruction. High anastomotic tension, low blood supply or postoperative infection are the main reasons for the difficulty in healing the anastomosis and causing anastomotic leakage. In response to these problems, the implantation of biological tissue engineering scaffolds is considered to be a new way to solve intestinal anastomotic leakage. At the same time, this research field is of great significance for strengthening clinical treatment and improving the quality of life of patients.
目前，自膨胀金属支架(SEMS)或自膨胀塑料支架(SEPS)是防治因晚期恶性肿瘤或其他恶性病变导致消化道重建术后发生吻合口漏的有效选择，但这些支架造成的狭窄形成、穿孔、移位、组织嵌入、二次手术取出等问题仍需解决。为了克服这些缺点，一些刚性生物可降解高分子支架和柔性生物可降解支架应运而生。其中，又以柔性支架的功能特性最为接近肠道组织结构，近年来受到广泛关注与研究。At present, self-expanding metal stents (SEMS) or self-expanding plastic stents (SEPS) are effective options for preventing and treating anastomotic leakage after digestive tract reconstruction due to advanced malignant tumors or other malignant lesions, but the problems of stricture formation, perforation, displacement, tissue embedding, and secondary surgical removal caused by these stents still need to be solved. In order to overcome these shortcomings, some rigid biodegradable polymer stents and flexible biodegradable stents have emerged. Among them, the functional characteristics of flexible stents are closest to the intestinal tissue structure and have received extensive attention and research in recent years.
但是柔性支架由于其材料本身柔韧性的特性，同时其在体内的固定方式依然采用的是利用缝合线将其与肠壁组织进行贴壁缝合固定。因此，使用该类柔性支架在体内进行与肠道组织的缝合时，医生操作者较难将两种同样具有柔韧及弹性的物体进行准确的贴合，并且行针缝合的位置也难以准确定位，这些都使得柔性支架的实际操作难度增加。However, due to the flexibility of the material itself, the flexible stent is still fixed in the body by suturing it to the intestinal wall tissue with sutures. Therefore, when using this type of flexible stent to sew the intestinal tissue in the body, it is difficult for the doctor to accurately fit the two equally flexible and elastic objects, and it is also difficult to accurately locate the position of the suture, which increases the difficulty of the actual operation of the flexible stent.

During the surgical operation, the doctor observes the light transmitted by the point light source assembly on the limiting part 11 as the identification site, determines the position of the suture groove on the operating part, and can insert the needle at the position of the suture groove to suture and fix the two ends of the flexible anastomotic stent with the intestinal tissue. A drawstring is tied to the fixing ring 13 of the auxiliary device. When the anastomotic stent is sutured and fixed to the intestinal wall, the auxiliary device is taken out from the intestine through the anus through the drawstring, that is, the implantation operation of the intestinal flexible anastomotic stent is completed, and the abdominal incision is also sutured. The power supply of the point light source assembly can be built into the base 1.
辅助装置还包括盖体3，在辅助装置未使用时盖体3与操作部2插接配合，也同时保护辅助装置内部结构不受破坏和污染。The auxiliary device further comprises a cover body 3, which is plugged into and matched with the operating part 2 when the auxiliary device is not in use, and also protects the internal structure of the auxiliary device from damage and contamination.
所述的操作部2内部还设有若干的支撑筋22，所述的支撑筋22与若干的弧面结构相互连接。支撑筋22支撑操作部增强辅助装置在肠道内对肠道柔性吻合支架的支撑作用。The operating part 2 is further provided with a plurality of supporting ribs 22, and the supporting ribs 22 are connected to a plurality of arc surface structures. The supporting ribs 22 support the operating part to enhance the supporting effect of the auxiliary device on the intestinal flexible anastomosis stent in the intestine.
