Controlled bending type PTCA guide wire

Abstract

The invention discloses a controlled bending type PTCA guide wire. The controlled bending type PTCA guide wire comprises winding wires, a supporting tube, a right controlled bending line, a left controlled bending line and a controlled bending handle, wherein the right controlled bending line and the left controlled bending line are both slidingly arranged inside the supporting tube, one end of each of the right controlled bending line and the left controlled bending line penetrates through the supporting tube and is connected with a head end which is in the shape of a half ball, the winding wires are arranged outside the right controlled bending line and the left controlled bending line in a sleeving manner, and arranged between the head end and the end face of the supporting tube; one end of the supporting tube is placed in the controlled bending handle, a left controlled bending controller and a right controlled bending controller are respectively arranged on the left side and the right side of the controlled bending handle, and respectively connected with the left controlled bending line and the right controlled bending line. The controlled bending type PTCA guide wire disclosed by the invention has the beneficial effects that the left controlled bending controller and the right controlled bending controller respectively control the tension and relaxation of the left controlled bending line and the right controlled bending line, so that the head end deflects left and right, and the deflection angle is determined according to the tension degree, thereby being capable of reducing damage of the guide wire to vessel walls.

Description

technical field [0001] The invention relates to a PTCA guide wire, in particular to a bending-controlled PTCA guide wire. Background technique [0002] Femoral artery or radial artery puncture is used to send the balloon catheter to the coronary artery stenosis lesion through PTCA guide wire, pressurize and expand, and release the stent to increase the inner diameter of the blood vessel and improve the blood supply of the myocardium, PTCA for short. In PTCA surgery, it is often encountered that the guide wire in the multi-branched vessel is difficult to control the guide wire to enter the target vessel because the plasticity of the previous guide wire is not suitable or the angle of the vessel is large, which brings certain troubles to the operation, and even needs to insert the guide wire into the target vessel. Withdrawal and remodeling, if multi-branch vessels are encountered many times, the operation will often fail due to the inappropriate plastic angle of the guide wir...

Problems solved by technology

In PTCA surgery, it is often encountered that the guide wire in the multi-branched vessel is difficult to control the guide wire to enter the target vessel because the plasticity of the previous guide wire is not suitable or the angle of the vessel is large, which brings certain troubles to the operation, and even needs to insert the guide wire into the target vessel. Withdrawal and re-plasticization, if multiple vessels with multiple branches are encountered, the operation will often fail due to the inappropriate plastic angle of the guide wire
