Intraoperative stent delivery system and use method thereof

Abstract

The invention provides an intraoperative stent delivery system and an use method thereof. The intraoperative stent delivery system is used for loading and delivering the intraoperative stent. The intraoperative stent delivery system comprises a main body operating handle, a main body lining bar and a branch swing mechanism; the main body lining bar is arranged at the front end of the main body operating handle; the branch swing mechanism is also arranged at the front end of the main body operating handle; the main body operating handle comprises a front end cover, a middle handle, a rear end cover, a main body stent release portion, a branch support release portion and a lock cover; the main body lining bar comprises a bending bar, a limit ball and a guide head; and the branch swing mechanism comprises a sliding block , a transmission bar and a U-shaped ring. The invention also includes a method by using the system to deliver the intraoperative stent. The system can be used for delivering and releasing the single branch intraoperative stent so that the single branch intraoperative stent can solve the problem that the intraoperative stent is difficult to be matched with branch vessels, especially for the anastomosis with the left subclavian artery, accordingly the dissociation, the blocking and the anastomosis of the super-aortic branch vessels can be reduced or avoided so as toreduce the difficulty of surgery as well as the trauma of the surgery.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an intraoperative stent delivery system used in cardiovascular surgery and a method for using the same. Background technique [0002] Aortic disease is a cardiovascular disease that seriously threatens human health. At present, the treatment of aortic lesions involving the ascending aorta, aortic arch, and part of the descending aorta is through surgical implantation of intraoperative stents, that is, Sun's Procedure. [0003] Sun's surgery was founded by Professor Sun Lizhong, and it is mainly suitable for patients with extensive thoracic aortic or thoracoabdominal aortic disease. Sun's surgery applies the new aortic arch replacement and elephant trunk stent surgery, implants stent-type artificial blood vessels in the descending artery, further simplifies the operation process, and improves the closure rate of the distal false lumen. Currently, this procedure is recognized by in...

Problems solved by technology

[0007] The purpose of the present invention is to provide an intraoperative stent delivery system and a method of using the intraoperative branch on-demand blocking intraoperative stent, the intraoperative stent delivery system is used to load and deliver the intraoperative stent, and the method for operating the system is used to Operate the intraoperative stent delivery system during the operation to solve the problem that the intraoperative stent is difficult to anastomose with the branch vessels in the prior art, especially the problem of anastomosis with the left subclavian artery, thereby reducing or avoiding the dissociation of the branch vessels on the arch. Blocking and anastomosis reduce surgical difficulty and reduce surgical trauma
