Problems solved by technology

The disadvantage of this method is that it needs to be implemented in a place where X-rays are installed, and X-ray protection is required;
[0004] (2) The blind method is used to insert the catheter. The disadvantage of this method is that the catheter cannot be placed remotely, and it is easy to cause complications such as heart and blood vessel damage and arrhythmia;
[0005] (3) Using a balloon floating catheter and using the power of blood flow to guide the catheter forward, this method is difficult to operate clinically, and there are risks of vascular damage and arrhythmia;
[0006] In particular, there is currently no technology and equipment to guide catheter placement, transvascular catheter diagnosis, and therapeutic procedures through catheter self-monitoring

Embodiment 1

[0041] Such as figure 1 and 4 As shown, the first ultrasonic probe device 2 is embedded in the tube wall of the catheter main body 1 . The first ultrasonic probe device 2 is arranged in the head end tube wall of the catheter main body 1, and the head end of the first ultrasonic probe device 2 coincides with the head end of the catheter main body 1; the head end of the first ultrasonic probe device 2 includes a plurality of first Ultrasonic transmitting and receiving device 3.

[0042] Each first ultrasonic transmitting and receiving device 3 transmits and receives ultrasonic beams, ie longitudinal ultrasonic beams 6 , along the longitudinal axis of the catheter body 1 . Such a structure enables this embodiment to detect blood vessel information in front of the catheter tip.

[0043] A first transmission channel 8 for transmitting information of the first ultrasonic probe device 2 is also arranged in the tube wall of the catheter main body 1 . One end of the first transmiss...

Embodiment 2

[0048] like figure 2 and 5 As shown, the second ultrasonic probe device 4 is arranged in the tube wall of the catheter main body 1 . The second ultrasonic probe device 4 is circumferentially arranged around the tube wall of the catheter body 1 and is located at a preset distance from the head end of the catheter body 1 .

[0049] The second ultrasonic probe device 4 includes a plurality of second ultrasonic transmitting and receiving devices 5, and each second ultrasonic transmitting and receiving device 5 transmits and receives ultrasonic beams outwards along the cross section of the catheter main body 1, that is, transverse ultrasonic beams 7. Such a structure enables this embodiment to detect the structural information and position information of the vessel wall and extravascular tissues and organs, so as to realize positioning and monitoring functions.

[0050] A second transmission channel 9 for transmitting information from the second ultrasonic probe device 4 is als...

Embodiment 3

[0055] like Figures 3 to 5 As shown, the ultrasonic vascular catheter described in this embodiment includes a catheter main body 1, and a first ultrasonic probe device 2 that emits and receives ultrasonic beams along the longitudinal axis direction of the catheter main body 1 is arranged in the tube wall of the catheter main body 1, And along the cross section of the catheter main body 1 , the second ultrasonic probe device 4 for emitting and receiving ultrasonic beams outward.

[0056] The first ultrasonic probe device 2 is arranged in the head end tube wall of the catheter main body 1, and the head end of the first ultrasonic probe device 2 coincides with the head end of the catheter main body 1; the head end of the first ultrasonic probe device 2 includes A plurality of first ultrasonic emitting and receiving devices 3 , each first ultrasonic emitting and receiving device 3 emits and receives ultrasonic beams, ie longitudinal ultrasonic beams 6 , along the longitudinal axi...

Abstract

The present invention relates to the technical field of medical apparatuses and instruments, especially to an ultrasound blood vessel catheter. The ultrasound blood vessel catheter comprises a catheter main body, and the catheter main body comprises a catheter wall and a center chamber; the catheter wall of the catheter main body is internally provided with a first ultrasonic probe device configured to transmit and receive ultrasonic wave beams in a y direction of the catheter main body, and the catheter wall of the catheter main body is internally provided with a second ultrasonic probe device configured to transmit and receive the ultrasonic wave beams outwards along the section of the catheter main body. The catheter main body is provided with the center chamber configured to hold otherapparatuses to implement monitoring and operation through the catheter. The ultrasound blood vessel catheter achieves ultrasound visual guidance and real-time location functions when the catheter proceeds along the blood vessel, and achieve real-time monitoring and location functions when the center chamber of the catheter implements sampling, monitoring, diagnosis and treatment processing through the blood vessel.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an ultrasonic vascular catheter. Background technique [0002] Intravascular catheters and intravascular diagnosis and treatment usually require real-time monitoring to achieve guidance, positioning, real-time guidance monitoring, diagnosis and treatment, and avoid damage to blood vessels and tissues and organs caused by catheters. The current monitoring of intravascular catheters or endovascular treatment The methods are: [0003] (1) Under the X-ray fluoroscopy and the first guidance of the metal guide wire, the vascular catheter is sent to the target position. The disadvantage of this method is that it needs to be implemented in a place where X-rays are installed, and X-ray protection is required; [0004] (2) The blind method is used to insert the catheter. The disadvantage of this method is that the catheter cannot be placed remotely, and it is easy to cause co...
