AI Technical Summary

Technical Problem

The length of the catheter end side pore segment of the existing neurointerventional thrombolysis device is fixed and cannot be flexibly adjusted according to the location and range of the thrombus, making it difficult to accurately control the dose of thrombolytic drugs, and there may be an ineffective thrombolytic range and risk of systemic bleeding.

Method used

A nerve interventional thrombolysis device including an inner cannula mechanism and a support for the outer cannula mechanism is designed. The amount of occlusion of the sealing liquid sac to the side hole of the discharge by the sealing liquid sac is adjusted through the end of the inner cannula body, and the dosage and scope of use of the thrombolysis drug are flexibly adjusted.

Benefits of technology

The dosage of thrombolytic drugs is flexibly adjusted according to the location and range of the thrombus, reducing the range of ineffective thrombolytic drugs, reducing the probability of excessive use of thrombolytic drugs, reducing the risk of systemic bleeding, and improving the effect and safety of thrombolytics.

Abstract

The invention relates to the technical field of interventional therapy, and discloses a nerve intervention thrombolysis device which comprises a medicine guide inner cannula mechanism and a supporting outer cannula mechanism, the supporting outer cannula mechanism comprises a cannula unit, a sealing control unit, a disinfection isolation unit and a cannula pushing unit, the sealing control unit is fixedly installed at one end of the cannula unit, and the disinfection isolation unit is fixedly installed at the other end of the cannula unit. The disinfection and isolation unit is fixedly installed on the surface of the sealing control unit, and the tube pushing unit is fixedly arranged on one side of the sealing control unit. According to the nerve intervention thrombolysis device, during thrombolysis, the blocking number of the hole sealing liquid bag to the medicine discharging side holes can be adjusted through stretching and retracting of the end of the inner sleeve body in the outer sleeve body, so that the using number and the arrangement length of the medicine discharging side holes can be flexibly adjusted according to the thrombus position and range, and dosage control over thrombolysis medicine is facilitated; the ineffective thrombolysis range is reduced, the probability of excessive use of thrombolysis drugs is reduced, the whole body bleeding risk is reduced, and the safety is improved.
