Project Name: Design of Vein-covered Stent System
Cooperation content: design analysis | appearance design | structural design | prototype production | accompanying running assistance
1. design analysis
Use scenario: minimally invasive interventional surgery for thoracic/abdominal aortic aneurysm or dissection, with a single introduction through the femoral artery and immediate closure of the break.
Core appeal:
Super-smooth introduction-crossing complex curved blood vessels without wrinkling;
• Precise release-support positioning error <2mm;
• Safe retracement-the transporter can be fully retrieved with zero vascular injury.
2. Design Language
Shape: the whole device "streamlined torpedo" shape, from the handle to the catheter gradually reduced diameter, reduce the visual resistance.
Color: handle deep sea blue + track silver, dotted with ice blue indicator lights, conveying "flexible tension and sense of technology".
Material: The handle is made of aviation aluminum + glass fiber reinforced PC, and the catheter section Pebax is multi-layer composite, giving consideration to both flexibility and pushing force.
3. Design Details
Streamlined lines interspersed: symmetrical "Speed-Edge" grooves on both sides of the handle guide fingers to buckle naturally, while reducing weight by 8%.
Segmented anti-skid pattern: thin diamond-shaped pattern in the front section (anti-skid for wet hands), wide wave pattern in the rear section (increase torque), and color depth to distinguish functional segments.
Hidden button: the release button is sunk 0.5mm into the surface of the handle to avoid accidental touch during operation; Tactile bump, gloves can also be used for blind positioning.
Guide wire rapid mouth: rotary bell mouth, 0.2 s to complete the guide wire insertion, reduce blood splash.
Stress diffusion ring: 0.3mm elastic TPU buffer is added to the transition area between the catheter and the handle, and the bending resistance is 30 ° without breaking.
Visual ruler: blue/white alternating rings at 5 cm intervals of the catheter, which can be clearly developed under X-ray to facilitate the operation to judge the delivery depth.
4. ergonomics
Holding: The elliptical section of the handle is 22 × 18mm, which is consistent with the grip angle of the medical pistol, and the palm pressure is reduced by 25% for long-term holding.
Torque: the handle is 135 mm long, the center of gravity falls on the root of the index finger, the one-hand rotation torque ≤ 0.15 N · m, and women can easily control direction.
Operating height: the patient lies flat on the table top 900mm, the operator stands elbow height 1150mm, the handle is naturally located at 1000mm, and there is no need to lift the shoulder.
Viewing angle: The top of the handle is 5 ° upward, and the operator can observe the LED status light when looking down, and the line of sight is coaxial with the catheter.
Force feedback: Provide "click" mechanical sound +0.1mm microshock at the moment of release, confirm that the bracket is successfully opened, and reduce the number of fluoroscopy.
Summary
The Genesis AORANO01 compresses the complex aortic covered stent into a 6F catheter controllable by one hand with the design language of "streamlined torpedo + flexible tension". Speed-Edge anti-skid groove, hidden button and stress diffusion ring enable the operative to release the stent accurately, safely and without fatigue in highly distorted blood vessels, thus truly making large blood vessel implantation "as simple as infusion".
