Described rack body length is 1-35mm, and external diameter is 0.2-0.35mm, and internal diameter is 0.1-0.25mm.
The housing of described rack body be biocompatibility high polymer housing, Stainless Steel Shell, golden shell body, silver-colored housing,
Platinum housing or nickel housing.
The beneficial effects of the utility model are：It is permanently effective to applying lime in the operation that Lai Mushi pipes are applied for expanding
The stenotic lesion position of family name's pipe is expanded, and then promotes aqueous humor discharge, reduces intraocular pressure, to reach the purpose for the treatment of glaucoma,
It is simple in construction, it is easy to process, and the presence of optical fiber can indicate the position of support in real time in implantation process, be brought to operation
Great convenience, and operation technique is simple, and reproducibility is strong, and complication rate is low.
Brief description of the drawings
Fig. 1 is the front view of the utility model structure
The structural representation that Fig. 2 is connected for conduit in the utility model with support.
Embodiment
The utility model is described further below in conjunction with accompanying drawing：It is a kind of that there is the Lai Mushi that applies for indicating push function to manage
Support, including rack body 1, and the guide device being connected with rack body 1, described rack body 1 are hollow tubular knot
Structure, described rack body 1 is provided with the gap for traversing head and the tail, and described rack body 1 is provided with otch 2, described otch 2
Otch 2 positioned at the both sides of gap, and both sides is symmetrical arranged, and the described end head of rack body 1 is provided with limited mouth 6；Described
Guide device includes conduit 3, connector 4, optical fiber 11 and injection device, and described one end of conduit 3 is provided with stopper slot 10, and leads to
The limited mouth 9 of the termination of 10 connecting bracket body of stopper slot 1 is crossed, the other end of described conduit 3 connects connector 4, described company
Device 4 is connect provided with two paths, one is injection passage 5, the described connection injection device 7 of injection passage 5, another is optical fiber
Optical fiber 11 is interspersed with path 6, the described connection laser generator 8 of optical fibre channel 6, described conduit 3.Described otch 2 is
Circular arc or kidney ellipsoid.Described otch is circular arc or kidney ellipsoid.Described rack body 1 is applied provided with biocompatible hydrophilic
Layer.Described biocompatible hydrophilic coating includes curative drug coating and polymeric coating layer.The length of described conduit 3 is
20-200mm, external diameter 0.1-0.25mm.The described length of rack body 1 is 1-35mm, and external diameter is 0.2-0.35mm, and internal diameter is
0.1-0.25mm.The housing of described rack body 1 is biocompatibility high polymer housing, Stainless Steel Shell, golden shell body, silver-colored shell
Body, platinum housing or nickel housing.
It is described for circular-arc cut 2, adjacent cut 2 is apart from for 0.45mm, and arc radius is 0.30mm；For oval
Shape otch, oval radius is 0.06mm, and adjacent oval central moment is the circular-arc cut and oval on 0.12mm, rack body 1
Shape otch does not have stress concentration effect, prevents tear, it is ensured that tension is slight and turns round control stability；Circular arc on rack body 1
Shape otch and kidney ellipsoid otch have along the inclined-plane of the direction of advance of conduit 3, it is ensured that the transporting of rack body 1, prevent from being implanted into
Journey is damaged to lesions position；Otch 2 is cut for bilateral, while proof strength, and hollow out ratio is provided to greatest extent, is had
Beneficial to aqueous humor discharge, the described length of rack body 1 is 10mm, and external diameter is 0.35mm, and internal diameter is 0.25mm.
Described gap width is 0.05mm, and the presence of gap improves expansion and the contracting property of support, helps to lead
The insertion and extraction of pipe 3.
