Device for conveying bracket in operation and method for mounting and releasing bracket in aortic arch operation

Abstract

The invention discloses a device for conveying a bracket in an operation, which comprises a coating film, a suture and a pulling line, wherein the suture is sewed on the coating film through the pulling line, the suture and the pulling line are used to sew two sides of the coating film, so that the bracket in the operation is closed and coated in the coating film, connection which can be disconnected when the pulling line is pulled out is formed between the suture and the coating film. An aorta is cut open on the end part of a vascular lesion position; the bracket in the operation, which is mounted on the conveying device, is conveniently and fast implanted into the corresponding lesion position including lesion positions of branch vessels; and thereby the corresponding suture can be released only by pulling out the pulling line; and then the bracket with branches in the operation is released and located in a blood vessel with branches, such as the aortic arch; and a cut is sutured after the conveying device is withdrawn. By using the invention, number of anastomotie stomas in the operation is reduced, the operation process is simplified, the operation time is shortened, the complications of the operation are reduced, the survival rate of the patient is improved, the treatment effect is increased, and wounds to patients with aortic arch parts and other diseases are more effectively reduced.

Description

technical field [0001] The invention relates to the field of medical aids for delivering intraoperative stents to corresponding lesions of the aortic arch under the condition of hybrid surgery, and more particularly, the improvement relates to an intraoperative stent delivery device and the installation and release of intraoperative stents during aortic arch surgery method. Background technique [0002] In 1994, American scholar Dake applied endovascular isolation technology to the treatment of descending aortic dissection and descending aortic aneurysm, creating a new approach for the treatment of thoracic aortic disease, and it was quickly promoted and used all over the world. Because intracavitary isolation technology generally uses percutaneous intervention to deliver instruments, it does not require incision of the patient's thoracic cavity. Its biggest advantages are less trauma, shorter operation time, and higher success rate. At present, most diseases of the thoraci...

Problems solved by technology

[0006] However, due to the complexity of the anatomical structure of the aorta, there is still no suitable delivery device that can conveniently and safely deliver the stent in the aortic arch to the corresponding lesion position of the aortic arch; Intraoperative stent with branches

[0007] Therefore, the existing technology still needs to be improved and developed
