Problems solved by technology

[0005]However, implants used for atrial shunt leave instruments at the stoma, which can easily lead to thrombosis, or the instruments fall off, forming embolism
In addition, the channel closure loses the shunt effect due to the endothelial attachment can cause the opening of the device to be blocked
In addition, there is a high risk of cutting intracardiac

Abstract

The invention relates to the technical field of medical instruments, and particularly discloses an atrial septal stoma device which comprises a first sheath tube, and the far end of the first sheath tube is connected with a supporting piece; the second sheathing canal sleeves the first sheathing canal, and the far end of the second sheathing canal is connected with a cutting assembly; the handle assembly is connected with the near ends of the first sheathing canal and the second sheathing canal and used for controlling axial movement of the first sheathing canal relative to the second sheathing canal so as to drive the supporting piece to be away from or close to the cutting assembly. According to the arrangement, the supporting piece can penetrate through the pre-opening hole in the atrial septum before the atrial septum tissue is cut, and the supporting piece in the contraction state and the cutting assembly can clamp the atrial septum tissue needing to be cut through movement of the first sheath tube; and the supporting piece is controlled to pull the cut tissue into the inner cavity of the cutting assembly and block the far-end opening of the cutting assembly. The situation that when the cutting assembly retreats out of the body from the interatrial septum, cut tissue is scattered into the body and embolism is formed is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an atrial septostomy device. Background technique [0002] At present, most heart failures begin with left heart failure, that is, the first manifestation is pulmonary circulation congestion. For chronic heart failure caused by continuous high pressure in the left atrium, the usual solution is to implant an atrial septum between the left atrium and the right atrium. into a shunt device that redistributes atrial blood volume and reduces interatrial pressure imbalances. [0003] Atrial septostomy is an opening in the patient's atrial septum, thereby forming a shunt between the left and right atrium, and is used to treat pulmonary hypertension (right-to-left shunt) or left heart failure (left-to-right shunt), and it has been clinically proven effectiveness. [0004] Traditional atrial septostomy methods, such as balloon atrial septostomy, have a tendency for myocardial tis...
