Abstract
The utility model relates to a medical prismatic grid-shaped net pipe support, which relates to a medical equipment used for treating various diseases of cavity channel stenosis. The utility model forms a prismatic grid-shaped net pipe shape. The crosspoints of the net are slime spots. The folding angles of the end part of the net pipe have the characteristics that adjacent folding angles formed randomly, and the folding angles of the end part form two interfaces with different heights through a head-up inspection. Adjacent folding angles can not carry out mutual intussusception or knotting trip after a warp shrinkage support is loaded to a push instrument. The support is ensured to sufficiently flick at the time of releasing, and restores the original shape. Experiments and clinic prove that the utility model has the advantages of higher safety and reliability when the utility model is used for treating cavity channel stenosis.
Description
This utility model belongs to medical apparatus and instruments, is applicable to the interior support treatment that body lumen is narrow.
In the medical treatment, open the method for partes corporis humani's luminal stenosis, just begin as far back as the 50-60 age with metal net shaped support.The support of various structures, shape respectively has quality, and wherein with Switzerland, the Wallstent prismatic webmaster support that SCHNEIDER company produces is more famous.The similar support of domestic structure with it has patent ZL94218587.0 and ZL95240960.7 at present.But no matter be external or state's inner support, its support termination all is concordant, top knuckle contour (as accompanying drawing 1).The support of this structure is after radial contraction is packed pusher into, and adjacent knuckle intussusception or knot is mutually stumbled, and exists bullet to open situation condition of poor (it has been proven in practice that) when being released in tube chamber.
The purpose of this utility model is guaranteed the prismatic grid network pipe holder that flicks fully after being a kind of radial contraction of design in tube chamber.
This utility model is to realize like this.Prismatic network two vertical knuckles are designed to: adjacent knuckle height is straggly, looks squarely and observes two different interfaces of knuckle formation height, end.When (being used for being contained in pusher), can avoid mutual intussusception of adjacent knuckle or knot to stumble with the contraction support in the footpath like this, guarantee to flick fully when support discharges.
Accompanying drawing 1 is the sketch map of existing prismatic network.
Accompanying drawing 2 is a sketch map of the present utility model.

This utility model embodiment as shown in Figure 2, the adjacent knuckle height in network two ends is straggly, advantage is adjacent knuckle not on sustained height, and mutual intussusception of adjacent knuckle or knot are stumbled when avoiding the radial contraction support, flicks fully when guaranteeing support from restrained condition to release.
The material of support can be selected elastic metallic yarn for use, as stainless steel silk, Ti-Ni alloy silk etc., can also answer film on metal, becomes covered stnet.
Experiment and clinically prove that all this utility model is respond well.
Claims (1)
1. a medical prismatic grid network pipe holder is characterized in that support two vertical knuckles are not contour, and adjacent knuckle height is straggly, looks squarely and observes two different interfaces of knuckle formation height, end.
