摘要
A percutaneous atrial septal defect plugging method with only guide of transthoracic echocardiography and an adaptive treatment guidance system thereof. The guidance system comprises: a catheter (FH), a guide wire (AD), and a load sheath (IK). The guide wire (AD) is designed to facilitate ultrasonic display and pass through an atrial septal defect, and comprises a main body (CD) made from a steel wire and a spindle-shaped head (AC) woven from a highly-elastic nickel-titanium wire, and a rivet is disposed on the top (A) of the head (AC). The catheter (FH) is used for adjusting a direction and controlling a diameter of the head (AC) of the guide wire, and is a hollow catheter. The catheter (FH) has a head and a tail, and a hole is disposed on each of the head and the tail and is inserted in by the guide wire (AD). The catheter (FH) comprises a bend segment (FG) close to the head and a straight line segment (GH) close to other parts, and smooth bending occurs between the bend segment (FG) and the straight line segment (GH) and an angle exists between them. A spiral interface is disposed on the tail of the catheter. The load sheath (IK) is used for sending the guide wire (AD) to the catheter (FH), and is of a hollow tabular structure. Symmetrical wing-shaped bumps are disposed on an outer wall of the load sheath (IK).
