Problems solved by technology

[0004] However, the applicant found that using the intraoperative stent prosthesis of the above invention, all branch blood vessels will still be cut off during the operation and sutured with the artificial blood vessels, which will increase the operation time and aggravate the pain of the patient.
At the same time, normal non-diseased branch vessels may be resected, causing unnecessary complications and risks

Embodiment 1

[0031] An intraoperative stent prosthesis provided by the embodiment of the present application, such as figure 1 As shown, the intraoperative stent prosthesis includes: a main body part 1 and a branch part 4, wherein: the main body part 1 includes an artificial vascular prosthesis main body 2 and a self-expanding stent main body 3, and the branch part 4 artificial vascular prosthesis branches 5 and self-expanding Bracket branch 6.

[0032] Artificial vascular prosthesis (comprising artificial vascular prosthesis main body 2 and artificial vascular prosthesis branch 5), fixed with self-expanding stent (comprising self-expanding stent main body 3 and self-expanding stent branch 6) by sutures, covering the self-expanding stent After being implanted into the human blood vessel, the outer wall of the artificial vascular prosthesis is closely attached to the inner wall of the human blood vessel, and the self-expanding stent plays a supporting role inside the artificial vascular pro...

Embodiment 2

[0036] The embodiment of the present application also provides an intraoperative stent prosthesis delivery device, which is used to deliver the intraoperative stent prosthesis provided in the first embodiment. like figure 2 As shown, the delivery device includes: a handle 7 , a pull rod 8 , a binding wire 9 , a branch sleeve 10 , a branch guide wire 11 , a liner 12 and a head end 13 .

[0037] Among them, such as image 3 As shown, the handle 7 is a rod with a hollow structure, and a small hole 14 is provided on the outer wall of one end of the handle 7 . The lining core 12 passes through the main body part 1 of the stent prosthesis in the operation, and one end enters the hollow structure of the handle 7 from the end of the handle 7 provided with a small hole, and is fixed with the handle 7, and the other end is fixed with the head end 13 by threads. After being fixed, the two ends of the main body part 1 of the stent prosthesis are in contact with the handle 7 and the hea...

Abstract

The invention discloses an intraoperative stand false body and a conveying device. The intraoperative stand false body comprises a main body part an a branch part, wherein the main body part comprises an artificial blood vessel false body main body and a self-expanding bracket main body; the branch part comprises an artificial blood vessel false body branch and a self-expanding bracket branch; the self-expanding bracket main body and the self-expanding bracket branch comprise a plurality of self-expanding rings respectively; and the artificial blood vessel false body main body and the artificial blood vessel false body branch are fixed with the self-expanding bracket main body and the self-expanding bracket branch through stitching threads respectively. By adopting the intraoperative stand false body and the conveying device provided by the invention, during an operation, all branch blood vessels are not required to be removed and sewn, thereby shortening the operation time, relieving patients' pain, reducing the probability of complicating diseases caused by the removal of normal non-pathological blood vessels.

Description

technical field [0001] The present application relates to the field of medical instruments, in particular to an intraoperative stent prosthesis and delivery device. Background technique [0002] For patients with aneurysms, when complex arch aneurysms involve the ascending aorta and extend to the descending aorta at the same time, the traditional operation must undergo a median thoracotomy or left subcostal thoracotomy to remove the diseased aortic vessel and some branch vessels (commonly known as "Three hairs"), artificial blood vessels are used to replace diseased blood vessels ("elephant trunk" technology), and normal blood vessels are sutured. In this type of surgery, there is often a diseased blood vessel that cannot be touched after thoracotomy, which cannot be treated and can only be waited for. In the next operation, open the chest from other parts for treatment. The two operations not only cause greater trauma and pain to the patient, but also have a great risk of ...
