Abstract
A caval vein filter is capable to prevent tilt and displacement, and has simple structure and thin guide wires. The filter is characterized in that the filter part is of a plurality of tinsel wires converge together, and the filter part is fixed by a metal cap or a tube to form an umbrella, where a part of the tinsel wires function as a fixing part, and others a guiding part. The structure herein makes the caval vein filter be characterized in the advantages of non-titing, non-displacement, and simple structure.
Description
Affiliated technical field:
This utility model is a kind of medical thrombus filter, the particularly vena cava filter that can prevent from and be shifted.
Background technology:
At present, known vena cava filter structure is made up of filter house and fixed part, and filter house and fixed part connect in a different manner.But, being subjected to that the caval vein inner blood flows, the influence of abdominal pulse and breathing, vena cava filter can produce and displacement in postcava.General vena cava filter complex structure can not prevent from and displacement that the thrombosis effect is filtered in influence behind the implantation postcava.
Summary of the invention:
In order to solve the deficiency of existing vena cava filter complex structure, inclination and displacement, this utility model provides a kind of vena cava filter, and this vena cava filter is simple in structure, can not only filter thrombosis, and can prevent the oblique and displacement in the postcava introversion.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of vena cava filter, form by filter house, fixed part, guide part, and it is characterized in that: assemble on the top of number of metal silk, and end is dispersed, and overall structure is umbrella; Wherein the accumulative tinsel in top forms filter house (1), and the tinsel of a dispersing part forms fixed part (2), and another part forms guide part (3); Fixed part (2) is spaced with guide part (3); The wire end of fixed part (2) is provided with the spinule hook; Described filter house (1) is fixed by metal cap or metal tube; Fixedly the metal cap of filter house (1) or metal tube are provided with the little hook of metal (4).
The beneficial effects of the utility model are, when can filter thrombosis, prevent the oblique and displacement in the postcava introversion, total only is formed by connecting with some one metal wires, and the guide part agent structure only is parallel symmetry, and form with the vertical several one metal wires in umbrella plane, simple in structure, the conduit supplying system is thinner, and is little to the human body wound, and can forever place, also can reclaim.
