Abstract
The utility model relates to a medical intracavitary support, which is a favorable device for curing various diseases of stenosis of the cavity channel. The utility model is a mesh-shaped tubular net pipe. The net pipe is made of the memory alloy wire and weaved in single wire; the surface of the net pipe adopts prismatic grids. The shape of the grid is variable. The cross point of the net is an active point. Proved by an experiment, the utility model is an excellent device for curing various diseases of stenosis of the cavity channel.
Description
This utility model relates to a kind of medical intracanal scaffold, belongs to medical apparatus and instruments.
Often running into patient in the medical treatment has esophagus, cardia that good, malignant stricture or obstruction of biliary tract take place, and diseases such as portal hypertension or urethral obstruction often need some apparatuses for enlarging these passages.
The purpose of this utility model provides a kind of narrow or block at tract, for enlarging the super-elasticity intracanal scaffold that tract designs.
The technical solution of the utility model is medical intracanal scaffold, and its shape is a piped webmaster of net form, is worked out by the memory alloy wire monofilament.The surface is the webmaster of prismatic grid.
Because the elastic performance of memorial alloy reaches monofilament and works out, the piped medical intracanal scaffold of net form has the super-elasticity characteristics, and the piped webmaster internal diameter of net form can change, so can adapt to the narrow symptom of various tracts, finishes the invention task.
Fig. 1 is embodiment of the present utility model.
Fig. 2 is the state after embodiment is out of shape.
Medical intracanal scaffold, its shape are webmasters, are piped webmasters of net form, and by the establishment of memory alloy wire monofilament, the surface is the webmaster of prismatic grid.
Two cornerwise length of the prismatic grid on inner support webmaster surface can be different, also can be identical, cornerwise variable-length, (diagonal increases, another root shortens) that is to say that the shape of prismatic is variable, the cross point that constitutes between each grid is a point alive, moves with growth, the shortening of the variation catercorner length of prismatic.
The variation of prismatic grid is the super-elasticity webmaster that changes with external applied load, variation of temperature.Along with the variation of net, caliber also changes, by D
AFade to D
M(Fig. 1, Fig. 2).
The inner support webmaster is by memory alloy wire monofilament volume, and the silk of establishment is the trend when being the silk establishment with the helix, and grid is that left and right sides helix intersects and the network of formation.Two ends of inner support webmaster have the bore of an end at least greater than the mid-level net bore, also can two end bores all greater than the mid-level net bore, but little in the middle of being, the structure of the taper (tubaeform) that the end is big.
The shape of inner support webmaster two ends is not to be a full circle, and is the sawtooth annular of multiple spot (multi-stylus head).
Experimental results show that this utility model is that a Nover practical is suitable for treating the narrow medical instruments of various tracts.
Claims (7)
1, a kind of medical intracanal scaffold is characterized in that its shape is a piped webmaster of net form, by memory alloy wire monofilament establishment, the surface is the webmaster of prismatic grid.
2,, it is characterized in that two catercorner lengths of prismatic grid are transformable by the described medical intracanal scaffold of claim 1.
3, by the described medical intracanal scaffold of claim 1, the cross point that it is characterized in that surface mesh is the point of living, and can change with the prismatic catercorner length to move.
