Intraoperative stent delivery system and intraoperative stent system

Abstract

The present invention provides an intraoperative stent delivery system and an intraoperative stent system. The intraoperative stent includes a main body stent and a side branch stent arranged on the main body stent and extending outward. The intraoperative stent delivery system includes a main body an inner lining and a side branch inner lining arranged on the main body inner lining, the side branch bracket is configured to be sleeved on the side branch inner lining, the main body bracket is configured to be sleeved on the main body inner lining, and the side branch The inner liner is oscillatingly arranged on the main body inner liner to synchronously drive the side support bracket to swing relative to the main body support. In the present invention, by setting the side branch lining that can swing relative to the main body lining, the side branch stent can be swayed synchronously relative to the main body stent, which facilitates alignment and easy implantation of the side branch stent and the left subclavian artery during operation, and avoids thoracotomy The time of freeing and suturing the left subclavian artery in the operation is too long, which increases postoperative complications, reduces the difficulty of operation, shortens operation time, and expands the scope of surgical indications.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an intraoperative stent delivery system and an intraoperative stent system. Background technique [0002] 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. Treatment of head and arch lesions. Such as figure 1 As shown, the current clinical treatment of aortic lesions generally adopts stent elephant trunk surgery, the principle of which is to open the median thoracotomy, make an incision on the aortic arch, and then implant a section of intraoperative stent 5 in the descending aorta 4, and then The proximal end of the middle stent 5 is connected to the artificial blood vessel 2 to replace the ascending aorta and the aortic arch 3, and finally the artificial blood vessel 2 is sutured with the human body's own blood vessels. [0003] However, t...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide an intraoperative stent delivery system and an intraoperative stent system to solve the problem that the intraoperative stent is difficult to anastomose with blood vessel branches in the prior art, especially the problem of anastomosis with the left subclavian artery, thereby reducing the number of thoracotomy operations. Reduce the difficulty of operation, shorten the overall operation time, reduce postoperative complications, improve the success rate and postoperative effect of thoracotomy, and expand the scope of application of patients
