Abstract
The invention belongs to the orthopedic metal rack of using of medical human luminal stenosis supportive treatment.It is woven into the diamond-mesh shape by an one metal wire, the two ends flare.The best angle of mesh is: 40 ° at α angle, and 140 ° at β angle, mouthful end is 1: 0.75 with the optimal proportion of interlude diameter.This metal inner support support force is even, and compressibility is good, imports human body easily, the anxiety of non-cracking; Can prevent to implant the migration and the displacement of back metal rack effectively.Processing technology is simple, and price is low, is suitable for use as body lumen, blood vessel, especially supports the permanent implanted property apparatus at big-and-middle angiostenosis position.
Description
The invention belongs to the orthopedic instruments (A61F) of medical human luminal stenosis supportive treatment.
Existing auto-expanding type internal metal rack is a tubulose, is folded into " Z " shape and special being welded of process by several extremely tens of one metal wires, and this shape makes it have certain elasticity.During treatment, metal rack is sent into narrow part by conduit, and to the body tube chamber, especially big, medium vessels stenosis produces the support of permanent implanted property.But the subject matter that it exists is: tubular shape is impacted because of blood flow or tube wall shrinks easily generation displacement and migration behind implant into body, and the supporting structure that " Z " shape is folding is loose, and support force is inhomogeneous, and easy deformation when being subjected to external force makes tube chamber narrow once more; Because of the welding of this metal rack process, joint area easily ruptures when implanting and after implanting; Its processing technology is extremely accurate, complicated operation, and China still can not produce, this type of support of import cost an arm and a leg (each reaches 3000～10000 yuans).The present invention develops in order to address these problems.
The present invention is woven into regular prism mesh shape (accompanying drawing) by an one metal wire, and two ends are tubaeform (1).
The netted auto-expanding type internal metal rack of the new shape of accompanying drawing sketch map
One one metal wire is woven into regular prism mesh shape tubular support.The acute angle of mesh (2, claim the α angle) is 30 °～45 °, and obtuse angle (3, claim the β angle) are 135 °～150 °; The two ends of tubular metal support are tubaeform (1), and a mouthful end (1) is 1: 0.65～0.85 with interlude (4) diameter ratio.Mesh optimum angle alpha angle (2) is 40 °, (3) 140 ° at β angle, and mouthful end (1) is 1: 0.75 with the optimal proportion of interlude (4) diameter.
Prove through zoopery and clinical practice: prism mesh support structure power of the present invention is even, the overall performance height; The compressibility of support and elasticity are all good, easily the ingress pipe intracavity; Displacement and migration after the opening of two loud-speaker shapes can prevent to implant effectively; Because of not welding the anxiety of non-cracking.The present invention possesses very high biocompatibility, and is harmless; Processing technology is simple, and is cheap, is medical human tube chamber and blood vessel, especially supports the permanent implanted desirable apparatus in big-and-middle angiostenosis position.
Claims (4)
1, a kind of orthopedic internal metal rack of medical human luminal stenosis supportive treatment is characterized in that being woven into regular prism mesh shape structure by an one metal wire, and the acute angle of mesh is 30 °～45 °, and the obtuse angle is 135 °～150 °.
2, internal metal rack as claimed in claim 1 is characterized in that tubular two ends are horn-like, and flared end and interlude diameter ratio are 1: 0.65～0.85.
3, internal metal rack as claimed in claim 1, its mesh best angle is: 40 ° at α angle, 140 ° at β angle.
4, internal metal rack as claimed in claim 2, the optimal proportion of its horn mouth and interlude are 1: 0.75.
