PYT-018 Medical Forceps Deformation Tester
The Peyotal PYT-018 Medical Forceps Deformation Tester integrates a micron-level displacement sensor with a closed-loop force control drive system to ensure high-accuracy dimensional auditing. Designed for full automation, the system executes the entire testing workflow, including force loading, pressure dwelling, automated unloading, and post-test tip gap measurement, with a single click. The intelligent controller precisely measures the opening distance of the tweezers’ tips before and after loading cycles, automatically calculating the permanent residual deformation value. With a flexible measurement scope of 0 to 300 mm and an adjustable driving speed of 0 to 300 mm/min, this compact 11 kg benchtop instrument provides standardized, operator-independent data logging for surgical instrument manufacturing facilities, clinical packaging lines, and scientific testing departments across Southeast Asia, Central Asia, Africa, and Latin America.
product details
The Medical Forceps Deformation Tester (Model: PYT-018) is a dedicated laboratory-grade mechanical verification system engineered and manufactured by Peyotal. Specifically designed to assess the permanent plastic deformation, elastic recovery, and tip alignment retention of medical tweezers and surgical forceps after applying rated clamping loads or repeated closing stress, this apparatus ensures medical instruments retain accurate tip closure without irreversible bending over long-term clinical use.
Standards: Fully compliant with the standard YY/T 0295 for medical forceps.

Q1: What is the exact laboratory testing principle for determining the deformation of medical tweezers?
A: The test evaluates whether tweezers undergo unrecoverable plastic deformation after experiencing typical or excessive clamping forces. The sample is clamped into the dedicated fixture connected to the precision drive mechanism. The system first records the initial tip opening distance. It then applies a specified clamping load at an adjustable speed (0 to 300 mm/min), holds the pressure for a set duration, and releases the load. The displacement sensor instantly remeasures the tip opening gap and automatically computes the permanent residual deformation.
Q2: Why is testing permanent deformation critical for surgical forceps?
A: During surgical operations, tweezers must open and close repeatedly while maintaining precise tip alignment to grasp delicate biological tissues or fine sutures. If the metal exhibits poor elasticity or excessive plastic deformation, the tips will fail to meet evenly or will remain partially splayed after repeated use, compromising tactile feedback and surgical accuracy.
Q3: How does the one-click automation workflow minimize human operator error?
A: The PYT-018 replaces manual calipers and non-standardized clamping methods with an automated process. Once the specimen is positioned and the parameters are confirmed, pressing the start button triggers the instrument to automatically load, dwell, release, and measure displacement in a single cycle. The internal microprocessor executes all calculations and generates standard numerical results without manual data logging.
Q4: What facility utilities and accessories are required to operate the PYT-018?
A: The PYT-018 is engineered for standalone plug-and-play installation on standard single-phase electrical outlets (220V / 50Hz or 110V / 60Hz based on destination grid requirements). It requires no external compressed air or hydraulic hookups. The delivery container includes the main instrument, specialized forceps mounting fixtures, thermal printing paper, a power supply cable, and an instruction manual.
