AI Technical Summary

Technical Problem

In the existing technology, the devices for treating pseudoaneurysms have insufficient safety and reliability. Direct injection of thrombin may affect blood flow in the artery, leading to the risk of thrombosis.

Method used

The procedure employs a cannula and puncture frame, including a cannula, puncture needle, occlusion needle, blunt needle, and injection needle. Puncture, occlusion, and thrombin injection are performed under ultrasound guidance to limit the coagulation area within the pseudoaneurysm. The guide and locking device ensure the stability and accuracy of the needle.

Benefits of technology

This improves the reliability and safety of pseudoaneurysm treatment, ensures that the coagulation area is limited to the pseudoaneurysm, reduces the impact on arterial blood flow, and improves the safety and efficiency of medical procedures.

Abstract

The invention relates to the technical field of medical instruments, and discloses a pseudoaneurysm treatment device which comprises a trocar system and an injection needle. The trocar system comprises a cannula, a puncture needle, a plugging needle and a blunt needle, and the puncture needle, the plugging needle and the blunt needle can move in the cannula; the front end of the puncture needle is a sharp head; a balloon is arranged at the front end of the plugging needle body; the front end of the blunt needle is blunt and is used for smearing thrombin; the injection needle is used for injecting thrombin into the pseudoaneurysm. The trocar system is used for achieving puncture and blocking and blood coagulation of the joint of the pseudoaneurysm and the artery, thrombin is injected into the pseudoaneurysm through the injection needle, the blood coagulation area can be limited in the pseudoaneurysm, and the reliability of pseudoaneurysm treatment is improved.
