Product overview A multi function knot tying training model designed for realistic practice and clear observation. Suitable for one handed knot tying, instrument knot tying, surgical knot tying, false knot tying and recognition, knot tying in confined spaces and large oblique spaces, thread cutting, vessel clamping, cutting, and knot tying training. Simulated blood vessel components are replaceable. Key benefits Comprehensive practice in one unit: Supports single handed and instrument techniques, identification of false knots, and manipulation in both small and large oblique working spaces. Realistic tissue feel: A unique magnetic system provides adjustable resistance to simulate different amounts of tissue pull. Elastic simulated blood vessels reproduce a lifelike handling experience during cutting and knot tying. Clear observation and assessment: The transparent glass construction allows instructors and trainees to view techniques from multiple angles for teaching and evaluation. Flexible training configurations: Three cylinder inserts create a range of deep structure spaces, enabling practice across varied anatomical scenarios. Inserts are easy to swap for rapid changes in training setup. Easy to use and transport: Special groove design streamlines installation and replacement of simulated vessels and components. The unit is simple to disassemble for storage and carrying. Key features and specifications Functions supported: one handed knot tying, instrument knot tying, surgical knot tying, false knot tying and recognition, knot tying in small spaces, knot tying in large oblique spaces, thread cutting, blood vessel clamping, cutting, and knot tying training. Replaceable simulated vessel: Elastic, realistic simulated blood vessel can be removed and replaced as needed for repeated practice. Cylinder system: Three different cylinder inserts provide multiple knot spaces and simulate a variety of deep structural configurations. Material: Transparent glass body for clear teaching, observation, and independent assessment. Magnetic tension system: Adjustable simulation of tissue pull to vary difficulty and realism. Installation groove: Special grooves for easy mounting, replacement, and secure component fit. Practical use scenarios Medical or surgical skills lab: Ideal for repeated practice of hand tying and instrument tying techniques under supervision, with clear visual feedback for instructors. Resident and advanced trainee workshops: Use the three cylinder configurations and magnetic tension settings to replicate deeper or more constrained operative fields and to train recognition and correction of false knots. Assessment and teaching sessions: The transparent glass material permits objective observation for skills assessment and step by step demonstration during courses. Why choose this model This training model combines multiple knot tying functions, adjustable tissue tension, and a transparent structure for effective teaching and evaluation. Its replaceable simulated vessels and interchangeable cylinders make it a flexible tool for a range of training scenarios, from basic knot practice to advanced deep space techniques.
