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 ...

Abstract

The invention belongs to the technical field of ultrasonic imaging, and particularly relates to an in-vivo interventional ultrasonic probe with a rotary positioning function and an ultrasonic imagingsystem comprising the in-vivo interventional ultrasonic probe. The in-vivo interventional ultrasonic probe provided by the invention comprises a guide mechanism, an ultrasonic mechanism and a calibration mechanism, wherein the guide mechanism comprises a sheath tube and a transmission shaft; the ultrasonic mechanism comprises an ultrasonic transducer, the calibration mechanism comprises a timer, amagnetic generator and a magnetic sensor, wherein the magnetic generator and the magnetic sensor are oppositely arranged on the sheathing canal far-end shell and the ultrasonic mechanism. When the ultrasonic transducer rotates relative to the far-end shell, the magnetic generator generates a non-uniform magnetic field in the circumferential direction of the rotating motion, and the magnetic sensor obtains magnetic field parameter changes. The position and speed of the ultrasonic transducer are calibrated, and the deviation of the actual position and speed of the ultrasonic transducer from theideal position and speed caused by the structural characteristics of the transmission shaft, the change of the friction between the transmission shaft and the sheath tube and other factors is eliminated, so that the ultrasonic imaging system provided by the invention avoids the problem of distortion during image synthesis.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic imaging, and in particular relates to an in vivo interventional ultrasonic probe with rotational positioning and an ultrasonic imaging system comprising the same. Background technique [0002] When diagnosing body cavity lesions, there are certain subjectivity and limitations in inferring purely from the changes in tissue surface morphology. In vivo interventional ultrasound imaging technology uses ultrasonic probes to intervene in the body to scan blood vessels, digestive tract, bronchus, heart and other tissues in the body, and can obtain relatively clear and accurate tomographic images of internal tissues, providing doctors with an objective basis for symptomatic treatment. in accordance with. [0003] An in vivo interventional ultrasound imaging device generally includes an imaging host, an in vivo interventional ultrasound probe and an external drive control unit. Among them, the interna...
