Embodiment Construction

[0059] The core idea of ​​the present invention is to provide an intraoperative stent system, including an intraoperative stent and an intraoperative stent delivery system. The intraoperative stent includes a main body stent and a side branch stent, and the side branch stent is arranged on the main body stent and extends to the outside of the main body stent. The intraoperative stent delivery system is used for loading and delivering intraoperative stents, and includes a main body inner lining, a side branch inner lining arranged on the main body inner lining, and an operating handle communicated with the main body inner lining. In particular, the side branch liner is swingably disposed on the main body liner, and the side support bracket is configured to be sleeved on the side branch liner, and the main body bracket is configured to be sleeved on the main body liner. In this way, when the side branch lining swings relative to the main body lining, the side branch bracket can ...

Abstract

The invention provides an intraoperative support conveying system and an intraoperative support system. An intraoperative support comprises a main support and a side supporting support arranged on the main support and stretching outwards. The intraoperative support conveying system comprises a main lining and a side supporting lining arranged on the main lining. The side supporting support is configured to be arranged on the side supporting support in a sleeving mode, the main support is configured to be arranged on the main lining in a sleeving mode, and the side supporting lining is arranged on the main lining in a swing mode to synchronously drive the side supporting support to swing relative to the main support. By the arrangement of the side supporting lining capable of swinging relative to the main lining, the side supporting support can synchronously swing relative to the main support, the side supporting support is aligned with the left subclavian artery to be easily implanted during an operation, it is avoided that the time of freeing and suturing the left subclavian artery in thoracotomy operation is too long, so that postoperative complications are increased, then the operating difficulty of the operation is reduced, the operating time of the operation is shortened, and the adaptation disease range of the operation is widened.

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...
