Problems solved by technology

However, this solution only solves the problem of removing calcified plaque, but the plaque after removal is still left in the blood vessel. If it cannot be removed from the human blood vessel, it will flow to other parts of the body with the blood, such as Heart, which poses a great threat to the health of patients after surgery

Embodiment 1

[0035] The following descriptions about the anteroposterior direction are all defined according to the penetration direction of the catheter assembly when it penetrates into the blood vessel 10 when the catheter assembly is in use, where the end that enters the blood vessel 10 first is the front, and vice versa is the rear.

[0036] see Figure 1 to Figure 3 The ultrasonic balloon catheter system shown includes a catheter assembly, an ultrasonic generating element 6 capable of emitting ultrasonic waves, and an ultrasonic control generator 8 for controlling the operation of the ultrasonic generating element 6 .

[0037] The catheter assembly includes a balloon catheter 1, the balloon catheter 1 includes an inner catheter 11 and an inflatable balloon 12 arranged at the front of the inner catheter 11, the inner catheter 11 passes through the lumen of the balloon 12 axially and can Fluid is passed into the inner cavity of the balloon 12, and the circumference of the balloon 12 is ...

Embodiment 2

[0058] Not shown in the figure, the main difference between the catheter assembly of this embodiment and the catheter assembly of Embodiment 1 lies in the different generating elements.

[0059] In this embodiment, in the catheter assembly, the ultrasonic generating element 6 is replaced by a generating element capable of emitting shock waves, so that shock waves are emitted during operation to break and peel off the calcified plaque 20 blocked in the blood vessel from the blood vessel wall.

Abstract

The invention discloses a catheter assembly capable of removing vascular obstruction plaques. The catheter assembly comprises a balloon catheter; the balloon catheter comprises an inner catheter and an expandable balloon arranged on the inner catheter; the catheter assembly further comprises a first catheter, a second catheter and a filter screen sleeve; the balloon catheter is sleeved with the first catheter in a relative sliding mode; the first catheter is sleeved with the second catheter in a relative sliding mode; the peripheral wall of the filter screen sleeve is in a net shape; a first sleeve is sleeved with the filter screen sleeve in a relative sliding mode; the front end part of the filter screen sleeve is fixedly connected to the front part of the first catheter; and the rear endpart of the filter screen sleeve is fixedly connected to the front part of the second catheter. After the obstructive calcified plaques in the blood vessel are removed, the catheter assembly can be used for removing the broken calcified plaques from the blood vessel, so that the risk caused by the fact that the calcified plaques are still left in the blood vessel and flow along with blood is avoided. The catheter assembly is simple in structure and convenient to operate.

Description

technical field [0001] The present invention relates to a catheter assembly capable of removing blood vessel blocking plaque. Background technique [0002] Vascular calcification refers to the deposition of calcium salts in the walls of arteries and veins, that is, calcified plaques on the inner walls of arteries and veins, which seriously threaten the health of patients. In recent years, for calcium deposition in blood vessels, a catheter with a balloon is usually inserted into the blood vessel by means of minor surgery, and the balloon is inflated when the balloon reaches the calcium deposit, and the catheter placed in the balloon is used. The electrodes work to release high-voltage pulses, creating shock waves that travel through the fluid and hit the balloon wall and calcified areas to destroy calcium deposits with repeated pulses. [0003] In the prior art, the method of generating shock waves in the human body is mostly used to remove calcified plaques in the blood ...
