Surgical Suture Tensile Testing Machine
Surgical Suture Tensile Testing Machine is specially designed for mechanical performance testing of medical surgical sutures. It can test breaking strength, knot pull strength, elongation at break and needle-suture connection strength of absorbable and non-absorbable sutures, meeting the inspection requirements of medical device manufacturers and testing laboratories.
Product Overview
This equipment adopts high-precision force sensor and servo closed-loop control system, equipped with anti-slip special clamping fixtures for fine filaments. It supports dry and wet state tensile tests, records force-displacement curves in real time, and automatically calculates test data. It is suitable for incoming inspection, batch production quality control and new material development of surgical sutures.
Applicable International Standards
- ISO 10552: Surgical implants — Absorbable and non-absorbable surgical sutures
- ISO 10334: Implants for surgery — Malleable wires for use as sutures
- ISO 2062: Textiles — Yarns from packages — Determination of single-end breaking force and elongation at break
Main Features
- High-precision force sensor, suitable for micro force test of fine surgical sutures
- Servo speed control, constant speed stretching, adjustable test speed
- Special anti-slip fixture to prevent thin suture samples from slipping during testing
- Real-time display of force-displacement curve, automatic capture of breaking force and elongation
- Automatic stop when sample breaks, overload protection function
- Professional test software, supports data storage, report export and batch test management
