Description

Technical Field

[0001] The invention relates to the field of medical instruments, and in particular to a puncture drainage tube with an ultrasonic probe and an auxiliary device. Background Art

[0002] In medical practice, it is often necessary to perform puncture drainage on lesions in solid organs or tissues, such as hematomas or abscesses. Because tissues are not transparent, some auxiliary means are generally used clinically to improve the accuracy of puncture. The common ones are: 1. Estimate the puncture direction and depth based on imaging data and surface landmarks. The advantage is that it is convenient and simple, but the disadvantage is that due to the baseline difference between preoperative and intraoperative, the puncture point often drifts. 2. Intraoperative B-ultrasound positioning. The advantage is real-time guidance and reliable accuracy. The disadvantage is that a sterile cover is required, the operation is complicated and easy to contaminate, and the B-ultrasound probe is large in size, which limits the operating space under skull drilling or laparoscopy. 3. Three-dimensional navigation system, which is accurate and reliable, but the disadvantage is that it requires a frame to be worn before surgery, CT or MR scanning and planning, high requirements for equipment and personnel, and expensive charges. Summary of the invention

[0003] The inventor has designed a new device and method for puncturing and draining lesions in solid organs or tissues by combining the advantages and disadvantages of conventional puncture auxiliary means. The present invention designs a drainage tube with an ultrasonic probe, integrates an ultrasonic chip at the head end of the drainage tube, obtains a certain scanning width by swinging the drainage tube, and uses the principle of single-element swing method to perform imaging. By recording the dynamic scanning echo data of a single ultrasonic chip, a real-time acoustic image of the scanning width is generated, thereby realizing real-time ultrasonic-guided puncture.

[0004] The technical solution of the present invention is: a puncture and drainage device with an ultrasonic probe, comprising: a silicone drainage tube, an ultrasonic probe, a puncture needle core, a position and angle sensor, an image processor and a display, the puncture needle core is inserted into the silicone drainage tube cavity, and its head end is flush with the head end of the drainage tube, the ultrasonic probe is fixed to the head end of the puncture needle core, the position and angle sensor is fixed to the tail end of the puncture needle core, the signal line of the ultrasonic probe is integrated inside the puncture needle core, and after merging with the signal line of the position and angle sensor, it is connected to the image processor and display through an extension wire.

[0005] The ultrasonic probe can emit ultrasonic waves based on electrical signals, and can also receive echoes and convert them into electrical signals. The position and angle detector can sense the relative displacement and angle change of the drainage tube with a needle core, and convert them into electrical signals. The signal of the ultrasonic probe and the signal of the position and angle detector are transmitted to the image processor through an extension wire. The image processor can integrate the signal of the ultrasonic probe and the signal of the position and angle detector, reconstruct an acoustic image, and display it through a display.

[0006] Advantages of the present invention:

[0007] 1. The ultrasonic probe is directly integrated into the head of the drainage tube to scan the target area in real time and select the appropriate puncture direction and depth. During the process, the Doppler effect of the blood vessels can also be used to detect whether there are large blood vessels passing through the puncture path. After entering the puncture path, the depth of the interface can be understood in real time to improve the accuracy of the puncture direction and depth;

[0008] 2. The imaging principle of the single-vibrator swing method is used to generate real-time acoustic images of the scanning area by recording the dynamic scanning echo data of a single ultrasonic chip. This avoids the use of ultrasonic chip array imaging, thereby realizing the miniaturization of the device and reducing the material cost. It can be designed as a disposable product to improve the safety of use;

[0009] 3. Its usage is similar to that of ordinary drainage tubes, which is easy to promote and popularize, and benefit patients. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0013] like Figure 1 As shown: a puncture drainage device with an ultrasonic probe, comprising: a silicone drainage tube 3, an ultrasonic probe 1, a puncture needle core 2, a position and angle sensor 4, an image processor and a display 6, the puncture needle core 2 is inserted into the cavity of the silicone drainage tube 3, and its head end is flush with the head end of the drainage tube, the ultrasonic probe 1 is fixed to the head end of the puncture needle core 2, the position and angle sensor 4 is fixed to the tail end of the puncture needle core 2, the signal line of the ultrasonic probe is integrated inside the puncture needle core 2, and after merging with the signal line of the position and angle sensor, it is connected to the image processing and display 6 through an extension wire 5 through a plug-in connector.

[0014] When in use, the operator holds the drainage tube 3 and the accessory device (ultrasonic probe 1, puncture needle core 2, position and angle sensor 4), and touches the drainage tube head end, that is, the ultrasonic probe 1, to a certain point on the surface c of the normal tissue b, so that the probe starts to emit ultrasonic waves and receive echoes, and the echoes are converted into electrical signals and transmitted to the image processor through the extension wire 5. After processing, a one-dimensional sonogram is obtained, which can demonstrate the depth information of different tissue interfaces c in the direction of the extension line of the drainage tube at the current position. The drainage tube head end remains unchanged at this contact point, and with this contact point as the turning point, the drainage tube is swung at a constant speed in a certain direction, so that the extension line of the drainage tube sweeps a fan-shaped area, and the echo signal of the ultrasonic probe is recorded during the whole process. At the same time, the data of the position and angle sensor 4 are collected and recorded, and the two-dimensional sonogram of the fan-shaped area is integrated to generate, so that the morphology and depth of the diseased tissue a can be known. Repeating this process in different directions can further confirm the location of the lesion. After selecting the ideal puncture direction, the drainage tube can be inserted into the tissue to the ideal depth under the guidance of the one-dimensional sonogram, the position of the silicone drainage tube 3 is maintained, the puncture needle core 2 and the ultrasonic probe 1 are pulled out, and the drainage tube puncture operation is completed.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
