Precise shaping device of tip end of coronary guide wire

Abstract

The invention discloses a precise shaping device of a tip end of a coronary guide wire, and belongs to the field of medical equipment. The device comprises a lower base body, and an upper base body rotationally hinged to one end of the lower base body through a rotating shaft; a lower bending part is arranged in the lower base body; an upper bending part matched with the lower bending part for bending the tip end of the coronary guide wire as a needed angle is arranged in the upper base body; the lower bending part has a bending convex angle of theta 1; correspondingly, the upper bending part has a bending concave angle of theta 2; theta 2 is equal to 360 degrees minus theta 1; and theta 1 is smaller than 180 degrees and not smaller than 90 degrees. The device can precisely shape the length and the angle of the tip end of the coronary guide wire, and can reasonably control the bending length and angle of the tip end of the coronary guide wire according to different branch diameters and angles of heart blood vessels of patients, so that the tip end of the coronary guide wire can be smoothly inserted in an appointed branch blood vessel. The device is convenient to carry, simple and fast in operation, safe, reliable, low in cost, high in recycling rate and broad in market application prospect.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a device for precisely shaping the tip of a coronary guide wire. Background technique [0002] In recent years, percutaneous coronary angioplasty for stenotic and completely occluded coronary arteries has become one of the most effective means of treating coronary heart disease. Coronary guide wire is a tool that must be used in percutaneous coronary angioplasty. The stent can be delivered to the diseased blood vessel through the guide wire. If the guide wire is to be selected correctly and enter the branch blood vessel smoothly, it must be pre-installed. Bend the tip of the guidewire at an angle. In the past, the bending of the tip of the guide wire was done manually by doctors based on experience. There was no special device that could quickly bend the tip of the guide wire, which made the bending angle of the guide wire inaccurate, which increased the risk of surg...

Problems solved by technology

In the past, the bending of the tip of the guide wire was done manually by doctors based on experience. There was no special device that could quickly bend the tip of the guide wire, which made the bending angle of the guide wire inaccurate, which increased the risk of surgery; at the same time, for manual During the bending process, it is often not possible to bend to a suitable angle at one time. Usually, multiple times of straightening are performed. Since the tip of the guide wire is very thin, it is not only difficult to recover after repeated force application, but also breaks. thereby destroying the guidewire
