PYT-023 Suture Needle Cutting Force Tester
The Peyotal PYT-023 Suture Needle Cutting Force Tester combines a high-performance PLC programmable controller, a 7-inch professional color LCD screen, an ultra-sensitive load cell, and a low-vibration transmission mechanism into a unified testing platform. Operating across a loading range of 0 to 30 N at controlled linear test speeds of less than or equal to 10 mm/s, the instrument captures cutting resistance profiles with a resolution of 0.01 N and a strict system accuracy error within 0.3 N. The intelligent controller plots cutting force changes in real time, computes both maximum peak incision force and average cutting force values, and provides automated pass/fail compliance assessment based on preset standard parameters. Housed in a heavy-duty 20 kg benchtop framework with an integrated thermal printer, the PYT-023 delivers reliable, operator-independent quality assurance for surgical suture production plants, cleanroom packaging facilities, and biomedical testing laboratories across Southeast Asia, Central Asia, Africa, and Latin America
product details
The Suture Needle Cutting Force Tester (Model: PYT-023) is a precision laboratory verification apparatus engineered and manufactured by Peyotal. Specifically developed to evaluate the edge cutting resistance, sharpness consistency, and cutting efficiency of bladed medical suture needles (including triangular cutting needles, reverse cutting angle needles, and spatula/shovel-head needles) when penetrating simulated tissue media, this system ensures suture needles minimize surgical trauma while delivering exceptional penetration smoothness.
Standards: Fully compliant with regulatory standards including YY0166-2018 (Suture Needle with Thread) and YY0043-2016 (Medical Suture Needle).

Q1: What is the exact laboratory testing principle and workflow for measuring suture needle cutting force?
A: The test evaluates the dynamic cutting resistance produced by the honed edges of a bladed needle during tissue entry. The suture needle specimen is secured in the specialized fixture on the linear transmission drive. The system drives the cutting edges downward through a calibrated test substrate or simulated membrane at a controlled speed (less than or equal to 10 mm/s). The precision sensor measures force fluctuations throughout the stroke, allowing the microprocessor to capture the peak cutting load and compute the average cutting resistance across the penetration depth.
Q2: How does the PYT-023 differ from standard puncture force testers (like the PYT-021)?
A: While puncture force testers primarily measure the initial piercing load of a needle’s conical or faceted tip point, the PYT-023 is engineered specifically for bladed needles (such as triangular, reverse-cutting, or spatula designs) where cutting edges actively slice through tissue. The PYT-023 provides a wider force capacity (0 to 30 N) and advanced algorithms to calculate both peak incision force and sustained average cutting resistance along the entire blade facet.
Q3: How does the automated pass/fail determination function support high-throughput laboratory QA?
A: Operators can preset standard threshold criteria matching regulatory standards or internal product specifications on the intelligent controller. Once the cutting stroke is completed, the system automatically compares the measured peak and average values against these limits, displaying an immediate visual qualification verdict on the LCD screen and logging the result to prevent manual scoring errors.
Q4: What facility utilities and hardware accessories are included in the delivery package?
A: The PYT-023 operates on standard single-phase AC electrical power (220V / 50Hz or 110V / 60Hz) and functions as a standalone benchtop system without requiring compressed air. Built into a vibration-damped 20 kg chassis, the package arrives complete with the tester mainframe, specialized clamping fixtures, calibrated verification weights, rolls of thermal printing paper, a power cable, and an operation manuall.
