Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to a highly supportive mesh structure. Background Technology

[0002] With the increasing number of patients with cardiac, cerebral, and peripheral cavity embolisms, children and the elderly often experience blockages in other cavities such as the trachea and esophagus. Quickly establishing and maintaining the patency of these cavities is essential for patient treatment. However, existing vascular and human cavity stents on the market lack sufficient support and cannot effectively establish the expected size for cavities with severe calcification or hard foreign objects.

[0003] Therefore, it is of great significance to design an application that can adapt to various cavities blocked in the human body, has strong support, and can establish cavities in various hard, sharp, and irregularly shaped foreign objects. Summary of the Invention

[0004] This invention proposes a highly supportive mesh structure. Its design advantages include strong support, enabling the establishment and maintenance of cavities for various hard, sharp, and irregularly shaped foreign objects obstructing the lesion site. This mesh structure is adaptable to various cavities obstructed in the human body, maximizing the effectiveness of the instrument and ensuring optimal treatment for the patient during the surgical procedure.

[0005] The technical solution of this invention is implemented as follows:

[0006] A highly supported mesh structure includes beam-column units and single expansion units. The beam-column units at both ends and the single expansion unit in the middle are connected to form a tubular mesh structure. The single expansion unit is composed of single expansion grids connected axially through bridge reinforcement. The crests of radially adjacent single expansion grids are arranged alternately.

[0007] A single expanded grid consists of positive and negative W-shaped structures.

[0008] The beam-column unit is composed of width modules arranged vertically.

[0009] A single expansion unit is horizontally connected to the width module.

[0010] The crest is a sine wave crest perpendicular to the axis of the pipeline structure, and its original state is approximately closed, while its expansion state is that each crest that makes up a single expansion unit extends outward from the circumference.

[0011] The bridge reinforcement and the single expanded grid form an angle on different planes, and after being connected, they form a tubular curved surface.

[0012] The number of individual expansion units ranges from 1 to 20, and the length of an individual expansion unit ranges from 5 mm to 200 mm.

[0013] The transverse width of the bridge reinforcement, width modules, and single expanded mesh ranges from 15μm to 500μm.

[0014] The radial thickness of the bridge reinforcement, width modules, and single expanded mesh ranges from 15 μm to 500 μm.

[0015] The number of individual expansion grids ranges from 3 to 55.

[0016] The processing techniques for the mesh structure include cutting, weaving, welding, bonding, or printing.

[0017] The beneficial effects of this invention are as follows:

[0018] The mesh structure of this invention has strong radial support, low axial shrinkage, no sharp angles, and stable mechanical properties. It can be adapted to various cavities in the human body and can establish and maintain cavities in various hard, sharp, and irregularly shaped foreign objects. This provides surgeons with a safer surgical procedure basis, increases the surgeon's treatment options, and reduces the pain and suffering of patients during and after surgery.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1

[0024] like Figure 1-2As shown, a high-support mesh structure includes a head beam-column unit 1, a tail beam-column unit 2, and several single expansion units 12. The head beam-column unit 1 is composed of several head width modules 3 arranged vertically, and the tail beam-column unit 2 is composed of several tail width modules 4 arranged vertically. Each single expansion unit 12 is composed of multiple head W-shaped structures 8 and reverse tail W-shaped structures 9 connected horizontally. The head peak 10 of each head W-shaped structure 8 and the adjacent peak 11 of the reverse tail W-shaped structure 9 together form a single expansion mesh 6. The single expansion meshes 6 are axially connected by bridge reinforcement 5 to form a single expansion unit 12. The head peaks 10 and adjacent peaks 11 of two radially adjacent single expansion meshes 6 are staggered. Two adjacent single expansion units 12 are connected by several middle width modules 7.

[0025] Example 2

[0026] like Figure 1-2 As shown, in the original state, the first peak 10 and the adjacent peak 11 in this invention are in an approximately closed state. In the expanded state, each peak of the first peak 10 and the adjacent peak 11 extends outward to the circumference. The bridge rib 5 provides radial support for each single expanded grid 6, so that the entire network structure has a high-strength radial support force, reducing the axial shrinkage rate of the entire network structure. The free combination and connection of the single expanded unit 12 and the single expanded grid 6 can ensure that the network structure of this invention can adapt to the use of all cavities of the human body.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
