Hypotube guidewire is a guidewire product with a hypotube structure. Compared with traditional springs or polymer structures, this kind of guidewire has unparalleled torsion control performance, resulting in hypotube guidewires becoming more popular in the domestic neurointervention market. Occupies absolute dominance. And because of the difficulty/cost of processing and manufacturing, the progress of domestic substitution is relatively slow.
The hypotube structure successfully solves the balance problem between the various properties of the guide wire, that is, it has good shaping performance and shaping retention ability, and has excellent torsion control performance. It is a truly 1:1 twist-controlled guidewire.
The micro laser cutting hypotube groove does not separate the hypotube. This structure has two reinforcing ribs, one more rib than the spring structure. Through simulation analysis, it can be known that the torsion transmission efficiency is higher. The cutting groove has a certain deflection angle, which can also reduce the time required for the guide wire to twist from the proximal end to the distal end.
The terminal price of the guide wire has become a key factor for manufacturers to develop such structured guide wires. Laser cutting is one way. However, the cost of femtosecond laser cutting or picosecond cutting and sample preparation is much higher than the factory price of the enterprise. Therefore, domestic The manufacturer currently has no similar guide wire products on the market.
BE-CU Prototype’s first-generation guidewire adopts plane cutting, while the second-generation guidewire adopts bevel cutting. However, judging from the feedback from the market and doctors, doctors and surgeons are more inclined to choose the first-generation guidewire. Although Simulation analysis shows that the micro-cut structure of the second-generation hypotube has a smaller bending radius and a softer head end, but the beam between the cutting micro-grooves becomes thinner, thereby reducing the transmission of shear stress. Efficiency, so the hypotube with the second generation structure is not as good as the first generation in terms of torque control.
