Embodiment

[0024] An ultrasonic puncture navigation method for electromagnetic positioning, such as Figures 1 to 2 Shown: consists of the following steps in turn,

[0025] A. Under the control of the navigation software subsystem 11, the position information of the probe and the puncture needle is tracked and collected through the puncture positioning system 9, wherein the puncture positioning system 9 is an electromagnetic puncture positioning system;

[0026] B. The electromagnetic puncture positioning system transmits the collected information to the ARM processor 10 in the navigation software subsystem 11, and then performs data calibration and post-processing;

[0027] C. The navigation software subsystem 11 transmits the calibrated and post-processed information to the ultrasound imaging device 2 for visual display.

[0028] The electromagnetic puncture positioning system in step A sends and receives information with the probe receiver 6 and the puncture needle receiver 8 thro...

Abstract

The invention belongs to the technical field of medical appliances, and relates to an ultrasonic puncturing navigation method, particularly to an ultrasonic puncturing navigation method based on electromagnetic location. The navigation method orderly comprises the following steps: A, tracking and collecting position information of a probe and a puncturing needle through a puncturing location system under the control of a navigation software subsystem, wherein the puncturing location system refers to an electromagnetic puncturing location system; B, transmitting the collected information to an ARM (Advanced RISC Machines) processor in the navigation software subsystem through the electromagnetic puncturing location system, and performing data correction and post treatment; and C, transmitting the information after being corrected and post-processed to an ultrasonic imaging equipment through the navigation software subsystem to realize visual display. The ultrasonic puncturing navigation method based on the electromagnetic location has the advantages of exact location, small volume and light weight; the method is nonradiative and is slightly affected by environmental factor; the puncturing needle path is displayed in real time; and the needle tip position can be clearly observed at random angle, the puncturing accuracy is improved, the hemorrhagic complication is reduced, and the safety is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an ultrasonic puncture navigation method, in particular to an electromagnetic positioning ultrasonic puncture navigation method. Background technique [0002] As an important part of interventional ultrasound, ultrasonic puncture navigation is an important means of ultrasound-assisted therapy. The traditional ultrasonic puncture navigation mainly adopts the guiding device method. This technology is relatively mature, but the angle between the direction of the puncture needle and the sound beam is still small, and the puncture needle is not parallel to the scanning plane, which easily leads to misjudgment of the position of the needle tip. Partial volume effect also often causes errors in monitoring and guidance, and the judgment of the location of the lesion depends largely on the experience of clinicians, which can easily lead to puncture errors, trauma and complications. ...
