Pseudo-aneurysm sealer

Abstract

The invention discloses a pseudo-aneurysm sealer, and belongs to the technical field of interventional medical instruments. The pseudo-aneurysm sealer comprises a sleeve, wherein the sleeve comprises an outer tube (1) and an inner tube (2); a balloon pipeline (3) is arranged between the outer tube (1) and the inner tube (2); the front end of the balloon pipeline (3) is connected with an elastic balloon (4); the outer tube (1) is provided with a plurality of side through holes (9); the pseudo-aneurysm sealer is further provided with a liquid medicine pipeline (10); the front end of the liquid medicine pipeline (10) is communicated with the side through holes (9). By adopting the pseudo-aneurysm sealer, a blood coagulation medicament can be prevented from flowing into arteries, the elastic balloon is used for compressing and sealing a pseudo-aneurysm leakage opening, and high-speed arterial blood flow from the pseudo-aneurysm leakage opening can be prevented from continually entering a tumor body, so that thrombus in the tumor body is formed more easily; meanwhile, the blood coagulation medicament is injected into the tumor body through the side through holes, so that formation of thrombus in the tumor body is further promoted, double guarantees of sealing the pseudo-aneurysm leakage opening are realized, and severe consequences can be avoided.

Description

technical field [0001] The invention relates to the technical field of interventional medical devices, in particular to a pseudoaneurysm sealer. Background technique [0002] With the gradual development of medical technology, interventional diagnosis and treatment techniques have been widely used, and iatrogenic pseudoaneurysms are becoming more and more common, but they cannot be completely avoided. Giant aneurysms may have symptoms of adjacent nerve compression damage and distal tissue ischemia. If there is mural thrombus formation in the tumor, thrombus migration may cause distal arterial embolism and produce corresponding symptoms, and it may also rupture and bleed due to trauma or increased internal pressure. Severe cases may even cause hemorrhagic shock and compartment syndrome. Therefore, timely and active treatment is necessary. [0003] The traditional treatment method is surgery, including parent artery ligation, end-to-end anastomosis of aneurysm resection, va...

Problems solved by technology

However, this method has the following disadvantages: (1) The duration of treatment is long; (2) Long-term pressurization causes pain and discomfort in the limbs, and may even be ischemic; (3) The success rate is low, only about 75%, and some anti-aging Patients treated with coagulation had lower success rates

[0006] However, there are still some problems in the current conventional ultrasound-guided pseudoaneurysm embolization therapy. Specifically, the possible complications of this method include the inadvertent retrograde flow of hemostatic drugs such as thrombin into the limb arteries, resulting in iatrogenic arterial thrombosis , causing serious consequences
