Problems solved by technology
The distal end of the thicker measuring guide wire has higher hardness. When it is inserted into the human body for guidance, especially when it is inserted into the weaker tissues in the human body such as the lungs and bronchi, its tip is easy to contusion the inner wall of the bronchi and cause damage to it. injury, leading to the occurrence of adverse events such as pneumothorax

Embodiment Construction
[0038] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.
[0039] In the interventional field, the end closer to the operator is usually called the proximal end, and the end farther away from the operator is called the distal end.
[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as common...

The invention discloses a measuring guide wire, which comprises a main body section, a guiding section connected with the distal end of the main body section, a developing mark is arranged on the main body section, and the guiding section also includes an elastic section and an elastic section. The flexible segment is connected to the distal end of the segment, and the flexible segment is made of polymer material and is softer than the distal end of the elastic segment. In the present invention, when measuring the guide wire against a wall, the flexible section bends first, and then the elastic section deforms, and the deformation range of the elastic section from its proximal end to the distal end becomes larger and larger, and the overall shape of the flexible section and the elastic section after bending is an arc Shape, to avoid sharp edges and corners during bending and damage to human tissues such as bronchi.
Description
technical field [0001] The invention belongs to the technical field of interventional therapy, and relates to an instrument for interventional therapy, in particular to a measuring guide wire. Background technique [0002] Under the guidance of medical imaging equipment, interventional therapy uses a guide wire to establish a delivery path, and transmits devices or diagnostic instruments into the human body through a catheter for diagnosis and local treatment of lesions. [0003] When using a guide wire to establish a delivery path, the measurement guide wire can be used for guidance. Once it is judged that the tip of the measurement guide wire is at the desired position, the catheter can be delivered along the measurement guide wire until the distal end of the catheter reaches the desired position. If the diameter length of the measuring guide wire is greatly different from that of the catheter, the distal end of the catheter will easily damage the diseased tissue after rea...
