PYT-021 Suture Needle Tip Puncture Force Tester
The Peyotal PYT-021 Suture Needle Tip Puncture Force Tester features an advanced 7-inch professional color LCD touchscreen with an intuitive menu interface to streamline testing parameter configurations and automated calibrations. Operating through a high-precision micro-force sensor core, the instrument applies vertical loads within a dedicated 0 to 2 N range at a controlled penetration speed of less than or equal to 10 mm/s, capturing minute resistance variations with a fine resolution of 0.001 N and an accuracy error within +/-0.009 N. The intelligent system displays live penetration force profiles and bending load values in real time, automatically determining result compliance and generating physical test reports via the integrated printer. Encased in a heavy-duty 20 kg benchtop framework to minimize mechanical vibration during micro-load capture, the PYT-021 provides standardized quality control for surgical suture production plants, cleanroom packaging facilities, and scientific regulatory laboratories across Southeast Asia, Central Asia, Africa, and Latin America.
product details
The Suture Needle Tip Puncture Force and Strength Tester (Model: PYT-021) is a specialized laboratory verification system engineered and manufactured by Peyotal. Built to conduct comprehensive mechanical quality evaluations on various medical suture needles (including threaded needles, reverse cutting angle needles, and round-bodied needles), this apparatus quantitatively measures point sharpness when penetrating artificial test membranes, the bending resistance of the needle body, and the joint connection strength of the needle tail.
Standards: Fully compliant with medical suture needle regulatory standards including YY 0043 and YY 0166.

Q1: What is the exact laboratory testing principle and workflow for evaluating suture needle tip puncture force?
A: The test evaluates the penetration sharpness of the needle point. The suture needle sample (diameter ranging from 0.2 to 1.3 mm) is clamped vertically into the dedicated fixture connected to the precision drive system. The instrument drives the needle downward at a controlled speed (less than or equal to 10 mm/s) to pierce a standardized artificial skin or test membrane. The micro-force sensor continuously logs the resistance encountered, capturing the initial entry force and displaying the peak penetration force on the 7-inch screen.
Q2: How does the PYT-021 perform multi-parameter testing for needle body strength and tail connection?
A: In addition to tip sharpness evaluation, the PYT-021 uses modular fixture configurations to test the bending resistance of the needle body and the tensile pull-off force of the needle-suture tail junction. By switching to the dedicated strength testing mode on the touchscreen menu, operators can apply bending or tensile loads to verify that the needle will not snap or detach from the thread under surgical handling.
Q3: Why is high measurement accuracy (0.001 N resolution) necessary for suture needle testing?
A: Suture needles, especially fine ophthalmic and cardiovascular micro-needles, generate low penetration resistance forces often under 1 N. Standard industrial load cells lack the sensitivity to detect micro-burrs, blunt bevels, or uneven coating lubrication at this scale. The PYT-021 uses a dedicated 0 to 2 N sensor with 0.001 N resolution and an error margin of less than or equal to +/-0.009 N to deliver precise, repeatable data for regulatory compliance.
Q4: What facility utilities and hardware components are included in the delivery package?
A: The PYT-021 operates on standard single-phase electrical power (220V / 50Hz or 110V / 60Hz) and functions as a standalone benchtop system without requiring compressed air. Built into a 20 kg anti-vibration chassis, the delivery package includes the tester mainframe, specialized suture needle clamping fixtures, thermal printing paper rolls, a power cable, and a comprehensive user instruction manual.
