Abstract
The invention discloses an ultrasonic guide method for a puncture needle. The method includes the steps of 1, using an ultrasonic probe to emit tissue detection pulse under certain frequency, and acquiring a tissue image after the pulse is reflected; 2, using the ultrasonic probe to emit puncture needle detection pulse under another frequency, and acquiring a puncture needle image after the pulse is reflected; 3, superposing the tissue image and the puncture needle image to obtain a detection image; and 4, repeating the steps 2 and 3 until the puncture needle reaches the specified position under the guidance of the detection image. The method has the advantages vivid ultrasonic images for human tissue and the puncture needle can be acquired, judgment on the position of the tip of the puncture needle is facilitated for doctors, and accordingly the puncture is guided to accurately reach a focus.
Description
Technical field
The present invention relates to medical instruments field, relate in particular to the ultrasonic leading device field of puncture needle.
Background technology
Puncture needle can carry out discharge, the collection of body fluid to the specific part in the health under the guiding of ultrasound probe, or the direct injection of medicine.Ultrasound probe can only be launched the ultrasonic pulse of certain characteristic frequency usually in the prior art, but tissue is different to hyperacoustic reflecting properties of same frequency with puncture needle, thereby can't obtain simultaneously clearly tissue image and puncture needle image.
Summary of the invention
The applicant can't obtain the clearly ultrasonography of tissue and puncture needle simultaneously for prior art, improve research, a kind of ultrasonic leading method of puncture needle is provided, thereby obtain the clearly ultrasonography of tissue and puncture needle, be convenient to the position that the doctor judges puncture needle head, accurately arrive focus with biopsy needle guide.
Technical scheme of the present invention is as follows:
A kind of ultrasonic leading method of puncture needle may further comprise the steps:
Step 1, ultrasound probe are launched the tissue detection pulse of a certain frequency, obtain tissue image after the pulse-echo;
The puncture needle that step 2, described ultrasound probe are launched another frequency detects pulse, obtains the puncture needle image after the pulse-echo;
Step 4, repeating said steps two, step 3 are until puncture needle arrives appointed part under the guiding of described detected image.
Beneficial effect of the present invention is: by ultrasonic signal difference human body tissue and the puncture needle of two kinds of different frequencies, thereby obtain respectively tissue image and puncture needle image, then process through image, with described tissue image and the stack of puncture needle image, obtain clearly detected image, be convenient to the position that the doctor judges puncture needle head, accurately arrive focus with biopsy needle guide.
Description of drawings
Fig. 1 is FB(flow block) of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the present invention includes following steps:
Step 1, ultrasound probe 8 are launched the tissue detection pulse 2 of a certain frequency under the control of control unit 1, obtain tissue image 3 after the pulse-echo;
Step 4, repeating said steps two, step 3 are until puncture needle arrives appointed part under the guiding of described detected image 5.
The present invention is by ultrasonic signal difference human body tissue and the puncture needle of two kinds of different frequencies, thereby obtain respectively tissue image 3 and puncture needle image 6, then pass through graphics processing unit 4, with described tissue image 3 and 6 stacks of puncture needle image, obtain clearly detected image 5, be convenient to the position that the doctor judges puncture needle head, accurately arrive focus with biopsy needle guide.
Above description is explanation of the invention, is not limitation of the present invention, and limited range of the present invention is referring to claim.In the situation that without prejudice to basic structure of the present invention, the present invention can do any type of modification.
Claims (1)
