(Nickel titanium shape memory alloy self expanding) vascular stent radial support force tester, radial support force tester (bath constant temperature type)

The nickel titanium shape memory alloy self expanding vascular stent radial support force tester is a precision device specifically designed to evaluate the mechanical properties of nickel titanium alloy self expanding vascular stents. Its core function is to simulate the physiological environment inside blood vessels, accurately measure the deformation, support force, and dynamic stability of stents under radial loads, and provide key data support for the development, production, and clinical application of stents.

1、 Working principle

Mechanical simulation system

Bracket clamping and loading: Fix the bracket with adjustable fixtures, apply radial compression or expansion force, and simulate the constraint effect of the vascular wall on the bracket.

Load sensor: Using high-precision pressure sensors, it captures real-time changes in the force on the bracket and converts mechanical signals into digital signals.

Dynamic control module: Driven by the control system or computer program, it can set modes such as uniform loading and step loading, accurately controlling loading speed, duration, and temperature conditions.

Data Collection and Analysis

Multi parameter recording: synchronously collect radial deformation, support force, friction force and other data of the bracket, and store them in the computer or cloud.

Visual analysis: Generate load deformation curves, fatigue life charts, etc. through professional software to quantitatively evaluate the elastic recovery rate, anti collapse ability, and durability of the support.

2、 Characteristics

Fully automated and intelligent

The color touch screen supports switching between Chinese and English, with an intuitive user interface; The PLC control system implements a one click testing process to reduce human error.

Equipped with fault diagnosis and automatic alarm functions, it improves testing efficiency and safety.

Multi functional testing module

Radial support force test: Evaluate the stability of the stent after expansion to ensure that it maintains sufficient support force within the blood vessel.

Dynamic fatigue testing: Simulate the cyclic pressure caused by cardiac pulsation to verify the anti fracture ability of the stent in long-term use.

Surface friction testing: Optimize the friction characteristics between the stent and the vascular wall or delivery system to reduce the risk of implant injury.

3、 Application Fields

Yi Medical Device Research and Development

Material optimization: By testing scaffolds with different nickel titanium alloy ratios, materials with superelasticity and biocompatibility were selected.

Structural design: Compare the mechanical properties of structural supports such as mesh, tube, and spiral to guide innovative design.

Production quality control

Batch testing: According to the standard, radial load testing is conducted on each batch of brackets to eliminate products with insufficient anti collapse ability.

Long term stability monitoring: Regularly test the performance degradation of the stent in simulated physiological environments to ensure its clinical validity period.

Clinical application support

Personalized medicine: Customize stents based on the size of the patient's blood vessels and verify their suitability through testing equipment.

Surgical plan optimization: Provide mechanical performance data of stents for complex cases (such as calcified lesions and bifurcated blood vessels) to assist doctors in selecting implantation strategies.

Regulation and Certification

Provide standardized testing data for the regulatory authorities of medical devices to assist in the market access approval of stent products.
