Problems solved by technology

[0002] With the increasing number of patients with embolism in the heart, brain, and peripheral cavities, children, the elderly and other groups often have blockages in the trachea, esophagus and other cavities. Quickly establishing corresponding and effective channels and effectively keeping the channels unblocked is the key to treating patients. It is a necessary means, but the existing vascular and human cavity stents on the market cannot effectively establish the expected size of the lumen with severe calcification and hard foreign bodies due to insufficient support

Embodiment 1

[0024] like Figure 1-2 As shown, a high-support network management structure includes a beam-column unit 1 at the head end, a beam-column unit 2 at the tail end, and several single expansion units 12 . The head-end beam-column unit 1 is composed of several head-end width modules 3 vertically arranged, the rear-end beam-column unit 2 is composed of several tail-end width modules 4 vertically arranged, and each single expansion unit 12 is composed of multiple head-end W-shaped structures 8 and the reverse end W-shaped structure 9 are horizontally connected, and the head peak 10 of each head end W-shaped structure 8 and the adjacent wave peaks 11 of the reverse end W-shaped structure 9 together form a single expanded grid 6 , the single expansion grids 6 are axially connected by bridge ribs 5 to form a single expansion unit 12, the peaks 10 at the head ends of the two adjacent single expansion grids 6 in the radial direction are arranged alternately with the adjacent peaks 11, a...

Embodiment 2

[0026] like Figure 1-2 As shown, in the original state, the head wave peak 10 and the adjacent wave peaks 11 in the present invention are in an approximately closed state, and in the expanded state, each wave peak of the head end wave peak 10 and the adjacent wave peaks 11 extends to the outside of the circumference, and the bridge rib 5 is Each single expansion grid 6 provides radial support, so that the entire network management structure has a high-strength radial support force, reducing the axial contraction rate of the entire network management structure, and the single expansion unit 12 and the single expansion grid 6 are freely matched and connected It can ensure that the network tube structure of the invention is suitable for use in all cavities of the human body.

Abstract

The invention provides a high-support mesh tube structure. The high-support mesh tube structure comprises beam column units and a single expansion unit, wherein the beam column units at two ends and the single expansion unit in the middle are connected to form a tubular mesh structure, the single expansion unit is formed by axially connecting single expansion grids through bridge ribs, and wave crests of the radially adjacent single expansion grids are arranged in a staggered manner. The mesh tube structure is high in radial support force, small in axial shrinkage rate, free of acute angle formation, stable in mechanical performance, applicable to various cavities of a human body and capable of building and maintaining the cavities in various hard, sharp and special-shaped foreign matter blockage cavities, a safer surgical operation process basis is provided for a surgeon, treatment means of the surgeon are increased, and pain and suffering of a patient during and after surgery are reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a high-support network management structure. Background technique [0002] With the increasing number of patients with embolism in the heart, brain, and peripheral cavities, children, the elderly and other groups often have blockages in the trachea, esophagus and other cavities. Quickly establishing corresponding and effective channels and effectively keeping the channels unblocked is the key to treating patients. The necessary means, but the existing vascular and human cavity stents on the market cannot effectively establish the expected size of the lumen with severe calcification and hard foreign bodies due to insufficient support. [0003] Therefore, it is of great significance to design an application that is suitable for various cavities of the human body, has strong support and can realize the establishment of cavities in the cavities of various hard, sharp and irre...
