Description

Technical Field

[0001] The utility model relates to the technical field of transcatheter aortic valve implantation, in particular to an anchoring auxiliary device for transcatheter aortic valve implantation. Background Art

[0002] Transcatheter aortic valve implantation, or transcatheter aortic valve replacement, involves inserting an interventional catheter through the femoral artery to deliver an artificial heart valve to the aortic valve area and open it, thereby completing the implantation of an artificial valve and restoring valve function. The operation does not require thoracotomy, so it is less traumatic and allows for a quicker recovery. It is performed by experienced cardiovascular physicians and surgeons.

[0003] Existing transcatheter aortic valve implantation generally involves making an opening in a blood vessel called the femoral artery through surgery in the groin, inserting an introducer sheath, and then inserting a guidewire through the introducer sheath into the aorta. A catheter is then inserted to perform a surgical operation on the aortic valve.

[0004] However, in actual surgery, there is a lack of a structure that can support and fix the connector, and the anchoring effect cannot be achieved, resulting in a medical staff member being required to hold the connector at all times, which not only increases the labor intensity, but also affects the operation of the surgeon. To this end, we provide an anchoring auxiliary device for transcatheter aortic valve implantation to solve the above problems. Utility Model Content
