Ring brush type thrombus cleaner

Abstract

The invention discloses a ring brush type thrombus cleaner which comprises a control handle, a control body, a first-stage hose, a second-stage hose and a third-stage injection hose movably penetrating through the first-stage hose, the second-stage hose and the control body, the second-stage hose is movably arranged at the front end of the first-stage hose in a sleeving mode, and the tail end of the first-stage hose is fixed to the front end of the control body. A sliding groove extending in the axial direction is formed in the control handle, a control rod is arranged in the sliding groove, the front end of the control rod is communicated with the third-stage injection hose, a thrombolytic agent / blood inlet communicated with the third-stage injection hose is formed in the tail end of the control rod, and an annular brush piece is arranged at the front end of the third-stage injection hose. A blood drawing inlet is formed in the side wall of the first-stage hose, and a blood drawing outlet communicated with the blood drawing inlet is formed in the control body. The ring brush type thrombus cleaner integrates three functions of mechanical thrombus cleaning, thrombolytic agent injection, blood extraction and injection backflow, is high in cleaning efficiency, and can relieve secondary damage of instruments to the inside of blood vessels.

Description

technical field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a thrombus clearing device integrating three functions of thrombus mechanical cleaning, thrombolytic injection, blood extraction and injection backflow. Background technique

[0002] With age, vascular diseases have become more serious, and the most common vascular blockage caused by blood clots is. There are currently two main solutions to the problems caused by thrombus. The first method is to inject a thrombolytic agent into the blood vessel to dissolve the clotted thrombus and make the blood vessel unblocked. This method is slow and costly; the second method is It uses medical devices to enter the blood vessels to mechanically remove the key thrombus. However, the current mechanical cleaning structures have obvious potential damage to the blood vessels, and it is easy to cause secondary damage to the blood vessels, resulting in internal rupture of the bloo...
