Abstract
The utility model relates to a rack for the insertion treatment, which belongs to the medical rack used in the human body for insertion type treating diseases, such as the vena cava, the aorta, etc. A Z-shaped stainless steel wire is bended into cylindrical shape, and a plurality of sections of cylindrical stainless steel wires are welded together through nodes provided with welding ribs to form the utility model. The utility model is characterized in that the bending part of each Z-shaped stainless steel wire is provided with a circular arc changed from the existing used dihedral and circle, the circular arc shape can be one part of the circle or an ellipse, and the centre angle is from 1 to 180 DEG. The utility model has the advantages of simple structure, easy formation, no stress concentration point, strong supporting power of the rack, etc., and can be smoothly transited.
Description
This utility model belongs to the medical support that uses in human body, be mainly used in the interventional therapy of diseases such as caval vein, aorta.
Such support is welded with 316L or the processing of 317L stainless steel silk usually.It is Z-shaped to adopt a fixed mold that stainless steel silk is processed into, and Z-shaped stainless steel silk is curved cylindric, with welding method two ends is coupled together.Add the weldering muscle between every joint, make two joint or three joints on request, constitute Z type support thus.It has simple in structure, be convenient to make, characteristics such as easy to use.316L that support is used or 317L super-low carbon stainless steel silk are international and domestic generally acknowledged medical embedded materials, have excellent biological compatibility, mechanical property and machining property.
But structurally, the design of Z type support corner is very important.Should not produce stress concentration, be difficult for fractureing, have higher rebound degree.Dihedral and circle are adopted in existing Z type support corner, and this folding form that turns easily produces stress concentration, easily fractures.
The purpose of this utility model provides a kind of difficult support that is used for interventional therapy that fractures.
Based on the foregoing invention purpose, this utility model curves cylindric by Z type stainless steel silk, again a few pitch circle column stainless steel silks are constituted by adding the welding of weldering muscle between the node, it is characterized in that: the design of described Z type stainless steel silk corner changes over circular arc by the dihedral and the circle of present use, described circular shape can be a circle or an oval part, and central angle is the 1-180 degree.
Compare with existing design, new design has realized rounding off, has following advantage:
(1) simple in structure, molding is easy, is easy to realize press production;
(2) has good geometrical stability;
(3) realized smooth transition, unstressed centrostigma, the support force of support is strong.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of this utility model support.
Fig. 2, Fig. 3 are that prior art medium-height trestle Z type folding turns place's structural representation.
Fig. 4 is that this utility model support Z type folding turns place's structural representation.
Fig. 2, Fig. 3 represent that respectively dihedral turns round and round turning round, and first kind of dihedral turns round and be easy to generate stress concentration at the place, summit, fractures.Second kind of circular design improved stress concentration, but still there is weak spot in circle with the straight transitions place.So we have designed circular-arc turning round.As shown in Figure 4.
Claims (1)
1, a kind of support that is used for interventional therapy, it curves cylindric by Z type stainless steel silk, again a few pitch circle column stainless steel silks are constituted by adding the welding of weldering muscle between the node, it is characterized in that: the design of described Z type stainless steel silk corner changes over circular arc by the dihedral and the circle of present use, described circular shape can be a circle or an oval part, and central angle is the 1-180 degree.
