FRT-A Tester for Determining Ductility and Elasticity of Suture Needle

Safety Testing Medical Equipment and Technology for medical device manufacturers and governmental quality department

Specification:

Principle of measuring ductility: bend the needle body through a given angle (i.e bend the straight needle 90°; bend the half-curved needle 3/8circle; bend the 3/8 circle needle straight ) and calculate the downstream travel, if the needle withstands the given amount of bending without cracking , it is considered as the eligible.

Principle of measuring elasticity: extend the needle by applying a given amount  of force, and remove the applied force until the chord length acquires the set value, After release of the load, the deformation amount of the chord length is measured immediately, the amount of increase and deformation is obtained by distance measuring unit independent of application of external force.

The tester consists of  PLC, touch screen , centimeter dial gauge , distance measuring unit, transmission unit, printer, etc. In use of  HMI touch screen, Operators can set parameters themselves, and the apparatus can realize antomatic runing and real time display of downstream  travel and the amount of increase and deformation, the built-in printer can print the test report.

Description:

Measuring range of centimeter dial gauge:0~25mm; error: within ±0.1mm; resolution: 0.01mm.

Measuring rage of distance measuring unit: 0~6mm; error: within ±0.2% of reading ; resolution: 0.001mm.
