Embodiment 1
[0064] This embodiment provides an internal interventional ultrasound probe 1 with rotational positioning, such as figure 2 As shown, it includes a guiding mechanism 11 , an ultrasonic mechanism 12 and a calibration mechanism 13 .
[0065] Such as figure 2 and image 3 As shown, the guiding mechanism 11 is used to introduce the ultrasonic mechanism 12 into the body, such as blood vessels, digestive tract, bronchus, heart and other internal tissues, including a sheath tube 111 and a transmission shaft 112 .
[0066] Such as image 3 As shown, the sheath tube 111 is an elongated shell structure, generally 0.8-2.5 m in length, including a proximal shell 1111 and a distal shell 1112, and forms a connected lumen. From the proximal housing 1111 to the distal housing 1112, the outer diameter of the sheath tube 111 may gradually decrease or remain unchanged. In this embodiment, the outer diameter of the sheath tube 111 remains unchanged, and along the direction perpendicular to ...
Embodiment 2
[0091] This embodiment provides an imaging system, such as Figure 14 As shown, it includes the internal body interventional ultrasound probe 1 with rotational positioning provided by Embodiment 1, an external drive control device 2 and an imaging host 3 .
[0092] The external control device 2 includes a drive control mechanism 21 and a connection mechanism 22 . Wherein, the connection mechanism 22 is connected with the drive shaft 112 of the in vivo interventional ultrasound probe 1, and the drive shaft 112 drives the ultrasonic transducer 122 to rotate to perform ultrasonic imaging; 122, magnetic generator 131, magnetic sensor 132 and timer 133 are connected to provide power supply, data collection and other functions.
[0093] The external control device 2 is also connected with the imaging host 2 by wired or wireless means, displays the information collected by the ultrasonic transducer 122 in the form of an image, and processes the information collected by the magnetic ...
