[0002] At present, in the treatment of cardiovascular obstruction disease (for example, non-CTO (Chronic Total Occlusion, chronic total occlusion) or CTO disease), firstly, a guide wire is inserted into a blood vessel. Secondly, a catheter reaches a lesion area and obtains tissue cells under the guidance of the guide wire through the blood vessel. Finally, imaging data of the tissue cells are obtained through the imaging technology, so that subsequent disease diagnosis and treatment are carried out.
[0003] In the prior art, firstly, for non-CTO disease, a straight guide needle is usually used to bend the guide wire, specifically, the guide wire is manually bent back and forth for multiple times to obtain an arc-bent guide wire (that is, the guide wire has a certain arc), so that the guide wire can better adapt to the width of the main blood vessel, for example, the greater the width of the main blood vessel, the greater the arc of the arc-bent guide wire. Secondly, for CTO disease, a needle tube type shaping needle is usually used to bend the end of the guide wire, specifically, the end of the guide wire inserted into the shaping needle is manually bent, so that the bent guide wire can better adapt to the angle between the main blood vessel and the branch blood vessel. For example, the greater the angle between the main blood vessel and the branch blood vessel, the greater the bending angle of the end of the guide wire.
[0004] However, firstly, under the help of the straight guide needle, the arc of the arc-bent guide wire obtained by manually bending the guide wire back and forth for multiple times is uneven. Secondly, under the help of the needle tube type shaping needle, the bending angle of the bent guide wire obtained by manually bending the guide wire is not accurate (that is, it is roughly accurate, but the accuracy is low).
