Vitrectomy head (taking the Jia Shinuode dual-airway high-speed vitrectomy head as an example)
Improve surgical safety: It is the first vitrectomy head in China with a basic cutting speed of 10,000 times per minute. It can more fully liquefy the vitreous body, reduce the pulling and disturbance of the floating retina, and thus reduce surgical complications.
Improve surgical efficiency and precision: It is the second vitrectomy head in the world and the first in China to adopt a dual-airway drive system. The cutting and resetting are controlled by two air source systems respectively, so that the resetting of the vitrectomy head no longer depends on the mechanical elastic force of the spring structure. It can more effectively control the opening and closing ratio of the vitrectomy head, allowing doctors to perform refined cutting and suction operations according to the surgical needs and the patient's condition.
Reduce costs: The purchase cost is expected to be more than 60% cheaper than imported brands, providing support for the equipment configuration and service upgrading of ophthalmic medical institutions at all levels.
Research and Development Background: In the process of industrial development, China's demand for wide and thick plates has increased. Traditional shearing equipment has low precision and slow efficiency. The dependence on imported large-scale shearing equipment restricts the transformation and upgrading of the steel industry. Northern Heavy Industries developed this equipment to break through this predicament.
Structural Design: Advanced mechanical analysis methods such as finite element analysis are used to accurately model and conduct stress analysis on the overall structure, determining the dimensions and materials of key parts. Through a reasonable structural layout and damping design, vibrations are reduced. Modal analysis is carried out on key components to avoid resonance, ensuring the strength and stiffness of the equipment.
Blade Design: The blade is made of materials with high hardness, high toughness, and good wear resistance, which are determined through experiments and simulations. An arc-shaped blade design is adopted to make the shearing process proceed gradually, reducing the peak value of the shearing force. The blade angle and the edge radius are optimized and adjusted according to the material and thickness of the plate, while also considering ease of replacement and maintenance.
Manufacturing Process: High-precision processing equipment is used. Methods such as hierarchical cutting and multiple measurement adjustments are employed to ensure the processing accuracy of large components. Materials such as high-strength alloy steel are used, and advanced welding processes such as symmetric welding, preheating, and post-heating are applied to reduce welding stress and deformation. The welding quality is strictly inspected.
Mechanical Head-cutting Shears (Taking the TRIMEasy Mechanical Head and Tail Removal Unit as an Example)
Structural Composition: It is mainly composed of a mechanical transmission device, a tool assembly, a paper roll conveying mechanism, etc. The mechanical transmission device is used to transmit power, enabling the tool to complete the cutting action; the tool assembly is a key component for achieving head and tail cutting; the paper roll conveying mechanism is responsible for accurately conveying the paper roll to the cutting position.
Working Principle: The mechanical transmission device drives the tool assembly to move. When the paper roll is conveyed to the set position, the tool cuts according to the preset program and parameters, accurately removing the head and tail parts of the paper roll. Due to its simple structure, there is no need for a complex vacuum adsorption system. It relies on the precise coordination of mechanical components to achieve efficient and stable cutting.
