Description

A kind of visual modified form device for thrombolysis treatment of arteriovenous internal fistula
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of visual modified form device for thrombolysis treatment of arteriovenous internal fistula.
Background technology
Internal arteriovenous fistula is Uremia in Hemodialysis " life line ", and internal fistula thrombosis is it loses function Main cause.Thrombotic reason includes: vascular conditions is poor, phlebitis, arteriosclerosis, diabetic angiopathy pipe, skill of performing the operation Art factor, hypercoagulability, hypotensive generation, prolonged and repeated puncture, hemostasis by compression are improper etc..
Previously the thrombotic Therapeutic Method of internal fistula mostly is surgical sectioning and takes bolt or again make internal fistula, and not only wound is big, And complication is more, it is preferred that slowly pump into Therapeutic Method with urokinase, intubation intervention medicine thrombolytic has danger relatively Little, expense is low, repeatable strong, the advantage such as thrombolytic effect is good.Existing thrombolysis catheter, after inserting thrombosis, passes through catheter drug delivery Hole release medicine thrombolytic, is slowly diffused at whole body and thrombosis.And clinically due to the diversity of internal fistula thrombosis, for thrombosis relatively Long, the thrombosis that difficulty is bigger often uses traditional puncture needle and maneuver to be difficult to molten opening, and point of puncture position is fixing, for The thromboembolism situation being continually changing is difficult to adjust the position puncturing conduit timely and effectively, causes thrombolytic effect the best, now, Patient's secondary puncture to be born puts misery and the risk of pipe, too increases the working strength of medical personnel.
So, if it is possible to during thrombolytic, the concrete condition according to thrombosis carries out observing and adjusting note timely and effectively Penetrate the position of thrombolytics, will significantly be dissolved into power for the thrombosis of various forms, reduce simultaneously patient's repeated localised puncture or The misery that operation etc. brings.
Summary of the invention
It is an object of the invention to overcome the shortcoming of prior art, it is provided that a kind of visual modified form internal arteriovenous fistula thrombolytic Device.
For solving above-mentioned technical problem, present invention employs techniques below measure:
