An Infrared Pulse Laser Induced Jet Generator

Abstract

The invention provides an infrared pulse laser-induced jet generator at least comprising an optical fiber, a connector, a casing, an inner guide tube, and a needle. The casing is tubular. The needle is fixedly mounted at the bottom of the casing. The upper portion of the casing is provided with a water inlet. The lower portion of the casing is provided with a water outlet. The water inlet and the water outlet are arranged on two sides of the casing respectively. A spacer is arranged inside the casing and disposed at the top of the casing. The spacer and the sidewall of the casing form a mounting cavity. The connector is disposed inside the mounting cavity. A rubber block is arranged between the connector and the spacer. One end of the optical fiber is connected with an infrared pulse laser, and the other end of the optical fiber penetrates the connector, the rubber block and a through hole of the spacer, enters the inner guide tube and extends below a bubble projection. The infrared pulse laser-induced jet generator has the advantages that thrombolytic drug is precisely delivered to a lesion part and even inside of the lesion part, little drug is used, thrombolysis is efficient, and the generator is safe and reliable.

Description

technical field [0001] The invention relates to an infrared pulsed laser-induced jet flow generator, which is used for cutting biological soft tissues, drug delivery and laser cleaning, and belongs to the technical field of laser medical supplies. Background technique [0002] With the further deepening of the aging society in our country, the number of the elderly continues to increase, and at the same time, their health and disease problems are becoming more and more serious, which has attracted extensive attention from scholars at home and abroad. Among them, thrombotic disease is a serious threat to human life and health, and its incidence rate ranks first among various diseases, and it has gradually increased in recent years. It is one of the focus and hot spots of contemporary medical research. When the vascular embolism time is equal to or more than 3 months, it is usually called Chronic Total Occlusion (CTO) disease. It can be diagnosed within hours of disease onset...

AI Technical Summary

Problems solved by technology

It can be diagnosed within hours of disease onset by nuclear magnetic resonance and single photon emission computed tomography. The advent of thrombolytic drugs (such as urokinase, plasmin) has promoted the dissolution of thrombus. The traditional treatment method is intravenous Thrombolytic drugs are delivered to the lesion by means of injection, catheter delivery or ultrasonic delivery, but the treatment time is short (arterial thrombosis should be completed within 6 hours after diagnosis) and the severe side effects of thrombolytic drugs (may cause gastrointestinal and intracranial hemorrhage) Treatment of Thrombotic Disorders Adds Great Difficulty

[0003] Traditional interventional therapy (such as intravenous injection, transcatheter drug delivery, ultrasonic drug delivery, etc.) takes a long time and requires a large amount of medication, resulting in high surgical risks and obvious drug side effects
