Problems solved by technology

The guiding process of cardiac catheterization is very complicated. This is because the blood vessels of the human body are very tortuous and winding, and only have specific elasticity. Therefore, when the wire of the cardiac catheterization is moving in the human body, extreme care must be taken to avoid any surgical accidents. operation

Embodiment Construction

[0022] In order to make the above-mentioned objects, features and characteristics of the present invention more comprehensible, the relevant embodiments of the present invention are described in detail as follows in conjunction with the drawings.

[0023] Please refer to figure 1 Shown is a schematic cross-sectional view of an alloy wire having shape memory properties and superelasticity according to an embodiment of the present invention. The alloy wire 1 with shape memory properties and superelasticity (hereinafter referred to as the alloy wire 1 ) includes a first segment 11 and a second segment 12 connected. The first phase change temperature of the first section 11 is between -30°C and 15°C, and the first phase change temperature is lower than an operating environment temperature to provide superelasticity. The second phase change temperature of the second section 12 is between 25°C and 90°C, and the second phase change temperature is higher than the ambient temperature ...

Abstract

The invention discloses an alloy wire with a shape memory characteristic and super elasticity and a manufacturing method and application thereof. The alloy wire with the shape memory characteristic and super elasticity comprises a first section and a second section, wherein the first section has a first phase change temperature value, the first phase change temperature value is smaller than a useenvironment temperature, the first section provides super elasticity, the second section is connected with the first section and has a second phase change temperature value larger than the use environment temperature, and the second section provides shape memory characteristic. Therefore, compared with a single alloy wire, the alloy wire provided by the invention has the advantage that the shapememory characteristic and the super-elastic beneficial effects can be respectively provided through different sections.

Description

technical field [0001] The invention relates to an alloy wire and a manufacturing method thereof, in particular to an alloy wire having shape memory characteristics and superelasticity, a manufacturing method and application thereof. Background technique [0002] Currently in dental root canal treatment, root canal files are used to debride infected pulp tissue. Root canal files are mostly made of a single alloy material, but there is a common problem of mechanical fatigue. Therefore, when the file of the root canal is placed in the root canal of the tooth of the patient to be treated, it is easy to break due to long-term rotation in the root canal. When a fracture occurs, the dentist must immediately stop treatment and attempt to remove the broken fragment from the root canal. This not only prolongs the treatment time, but may even endanger the health of the patient because the broken fragments cannot be removed. [0003] In addition, the current method of diagnosing cor...
