Thrombus removing system

Abstract

The thrombus removing system comprises a first instrument, a second instrument and an in-vitro fluid auxiliary mechanism, the first instrument comprises a guide wire, a cutting mesh basket, a thrombus cutting tube, a catheter mechanism and a handle, the second instrument comprises a catheter mechanism, and the catheter mechanism comprises a balloon, a double-layer catheter and a catheter head end; the first instrument and the second instrument are located at the two ends of the bolt block respectively, and the other ends of the first instrument and the second instrument communicate with the in-vitro fluid auxiliary mechanism. The cutting net basket is welded or bonded on the thrombus cutting pipe, the thrombus cutting pipe is connected to the handle through a mechanical device, and the front end of the thrombus cutting pipe is used for penetrating through the catheter mechanism and then acting on the thrombus block; the balloon is adhered to the outer tube of the double-layer catheter, the port of the double-layer catheter close to the balloon end is closed, and an air hole is formed in the joint of the outer tube of the double-layer catheter and the balloon. According to the thrombus removing system, the suction efficiency is greatly improved, blood vessels are prevented from being squeezed, wizened and damaged, and pretreated thrombus can be continuously sucked out of a body through the suction cavity.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a thrombus removal system. Background technique [0002] Lower extremity venous thrombosis (Deep Vein Thrombosis, DVT), together with pulmonary thromboembolism (Pulmonary Embolism, PE), is called Venous Thromboembolism (Venous Thromboembolism, VTE). With the aging of the population and changes in human lifestyles, VTE has become a worldwide health crisis, with more than 10 million people diagnosed each year. DVT can be simply divided into: inferior vena cava thrombosis, iliofemoral vein thrombosis and calf venous plexus thrombosis according to the location of thrombosis. Due to the obvious symptoms in the acute phase and the strengthening of people's health awareness, many patients can Treated in acute thrombotic state. [0003] Existing treatment methods mainly include thrombectomy, catheter-contact thrombolysis, and percutaneous mechanical thrombectomy. The main dr...

AI Technical Summary

Problems solved by technology

The main disadvantages are: vasculotomy and thrombectomy have large surgical trauma, high risk, multiple complications, and high difficulty of operation

At the same time, there is incomplete thrombolysis and other organ bleeding in the whole body, and the curative effect is uncertain

Subcutaneous puncture mechanical thrombectomy is better for small thrombus. When taking longer and larger thrombus, the suction tube may be blocked, and the long-term negative pressure will lead to excessive blood loss.
