PYT-024 Suture Diameter Measuring Instrument
The Peyotal PYT-024 Suture Diameter Measuring Instrument features an industrial-grade 7-inch capacitive touchscreen with an intuitive menu-based interface, providing a streamlined and standardized workflow for testing personnel. Programmed with specialized software supporting multi-level access management, the system ensures data traceability and meets stringent laboratory audit requirements. The instrument applies deadweight load through a precision circular presser foot (12.7 +/- 0.02 mm diameter) onto a heavy-duty reference anvil (50 mm diameter), maintaining a flatness within 0.005 mm and parallelism within 1 per mille. It delivers standard deadweight pressure of 210g +/- 3g (and reduced loading not exceeding 60g for ultra-fine sutures <= 0.4), measuring wire thickness with an ultra-fine resolution of 0.001 mm. The system automatically executes testing routines with preset parameters, records diameter points along the suture length, and outputs comprehensive statistical reports via the integrated micro printer. With support for remote updates and diagnostics, the PYT-024 serves as an essential quality assurance asset for surgical suture manufacturers and testing laboratories across Southeast Asia, Central Asia, Africa, and Latin America.
product details
The Suture Diameter Measuring Instrument (Model: PYT-024) is a specialized laboratory-grade dimensional verification system engineered and manufactured by Peyotal. Specifically designed to determine the precise cross-sectional diameter, wire thickness uniformity, and caliber compliance of medical sutures (including absorbable and non-absorbable surgical threads across nominal specifications from 0 to 12), this instrument ensures consistent mechanical strength, predictable degradation rates, and optimal clinical knot security.
Standards: Fully compliant with regulatory standards including YY 1116-2020 (Absorbable Surgical Suture) and YY 0167-2020 (Non-Absorbable Surgical Suture).

Q1: What is the exact laboratory testing principle and workflow for measuring surgical suture diameter?
A: The test evaluates the cross-sectional thickness of the suture under standardized compressive loading to eliminate measurement distortion caused by the soft, flexible nature of fibrous materials. The suture specimen is placed flat across the 50 mm reference anvil. The precision presser foot (12.7 +/- 0.02 mm) is lowered gently onto the suture, applying a constant deadweight force (210g +/- 3g for standard sizes, or <= 60g for ultra-fine sizes <= 0.4). The high-precision displacement sensor reads the vertical displacement at 0.001 mm resolution, automatically calculating and logging the true diameter without manual dial-gauge errors.
Q2: Why is strict control over contact surface flatness, parallelism, and deadweight force necessary for suture caliber testing?
A: Surgical sutures (especially braided multi-filaments and absorbable polymers) are viscoelastic and easily compressed. If the presser foot is tilted, uneven, or loaded with non-standard force, the suture will deform irregularly, leading to false dimensional readings. Maintaining flatness <= 0.005 mm, parallelism <= 1 per mille, and tightly regulated deadweight loads guarantees repeatable, audit-ready data across different manufacturing batches.
Q3: How does the software system support automated batch testing and multi-level user management?
A: The PYT-024 allows operators to select the suture specification (from 0 to 12) directly on the 7-inch capacitive touchscreen. The instrument automatically runs multi-point measuring sequences, computes statistical averages, maximum/minimum deviations, and pass/fail thresholds against YY 1116 / YY 0167 standards. Built-in multi-level user management restricts parameter calibration to authorized supervisors, preventing unauthorized modifications and ensuring compliance with regulatory data integrity rules.
Q4: What facility utilities and hardware components are included in the delivery package?
A: The PYT-024 operates as a standalone benchtop system powered by standard single-phase electrical power (220V / 50Hz or 110V / 60Hz) without requiring compressed air or hydraulic connections. The standard package includes the testing mainframe, standard calibrated deadweights for both regular and fine suture ranges, rolls of thermal printing paper, a power cable, and a comprehensive instruction manual.
