AI Technical Summary

⚠Technical Problem

In existing ablation devices, during the sheath retraction process, the umbrella-shaped electrode support units tend to come together at the bends at the front ends of adjacent support units, making it difficult to retract the sheath and prone to breakage, thus increasing potential risks.

⚗Method used

An ablation device was designed, whose ablation component includes multiple deformation units. By limiting the circumferential side edges of two adjacent deformation units to be radially misaligned along the ablation component, adjacent units are prevented from pressing together, reducing the risk of breakage. The sheath can be smoothly retracted by axial movement of the push tube and the outer sheath tube.

🎯Benefits of technology

This effectively avoids damage to the ablation components during the sheath retraction process, reduces operational difficulty and risk, and improves the safety and reliability of the device.

Abstract

The utility model discloses ablation device, including ablation component, ablation component has the first state of self -unfolding and presents funnel -shaped when not being radial constraint, and the second state of deformation and gathering when being radial constraint, ablation component includes support framework, and support framework includes a plurality of deformation units at the distal end side, and a plurality of deformation units are peripherally surrounded arrangement, and the surrounded plurality of deformation units are adjacent to each other and can all relatively and independently deformation with adjacent deformation unit, at least including two adjacent deformation units in a plurality of deformation units, when ablation component is in the first state, two adjacent deformation units periphery side edge of mutual approach is radial mislocation of ablation component. The utility model discloses ablation device, at least solves the problem that ablation component is not easy to advance sheath.
