Description

Ultrasonic interventional ablation system and working method thereof

The present invention relates to the field of ultrasound guided ablation, and more particularly to an ultrasound interventional ablation system and a method of operation thereof. Background technique

The United Nations World Health Organization's International Agency for Research on Cancer (IARC) reports that 12.7 million cancers were diagnosed in 2008, and 7.6 million people died of cancer. In 2030, there will be approximately 21.4 million cancer patients diagnosed worldwide, and 13.2 million people will die of cancer. At present, China's tumor outbreak rate and mortality rate are accelerating. Tumor interventional therapy has been regarded as one of the most important treatments in the clinic. Ultrasound interventional therapy is one of the most developed, and has a clear therapeutic effect on liver cancer, lung cancer and thyroid cancer. In China, liver cancer is one of the most common malignant tumors. The annual death rate of liver cancer is 300,000, and the mortality rate of liver cancer accounts for the second place in malignant tumors. Among the many therapies for treating liver cancer, surgical resection is still the first. 80% of patients with liver cancer have poor liver function and coagulation mechanism due to cirrhosis, or cannot be surgically removed due to constraints such as mass and poor heart and kidney function. The remaining 20% of patients with liver cancer are resected even after surgery. Up to 70%. Liver cancer cells are usually not sensitive to chemotherapy and radiation. Therefore, various non-surgical interventional treatments have become an important means of clinical treatment of liver cancer.

Ultrasound is widely used for interventional guidance and intraoperative observation during clinical tumor interventional therapy. Tumor thermal ablation based on microwave tumor ablation devices and radiofrequency tumor ablation devices is one of the most widely used tumor interventional ablation techniques. The basic principle of the above two kinds of thermal ablation is that the ablation needle is ultrasonically guided to the target tumor area, and the ablation needle is used to heat the target area to a certain temperature to achieve inactivation of the tumor area.

At present, in the process of clinical tumor ablation, radiofrequency ablation equipment (microwave ablation equipment) and ultrasound design All are independently controlled. When the doctor is in clinical use, he cannot see the ultrasound-guided image information and the working parameter information of the interventional ablation device at the same time. It is necessary for several relevant personnel to separately control the relevant ablation device and the ultrasound device, and have higher requirements for the relevant personnel. In the process of tumor interventional ablation, the ultrasound equipment and ablation equipment need to be placed next to the hospital bed, occupying a large amount of ward space. The ultrasound equipment has no special intervention ablation procedure, and the operation process is complicated. In the process of interventional ablation, the clinician needs to take care of the manipulation of the two devices. During the operation, it is necessary to interact with different devices through multiple human interactions, which may lead to misoperation or untimely response. Summary of the invention

The invention provides an ultrasonic interventional ablation system and a working method thereof, which enable a doctor to completely grasp relevant information in each ablation process and independently control relevant equipment in the process of interventional ablation, thereby improving the quality of ablation.

Example

Ultrasound is widely used for interventional I and intraoperative observation during clinical tumor interventional ablation. Tumor thermal ablation based on microwave tumor ablation devices and radiofrequency tumor ablation devices is one of the most widely used tumor interventional ablation techniques. The basic principle of the above two kinds of thermal ablation is that the ablation needle is ultrasonically guided to the target tumor area, and the ablation needle is used to heat the target area to a certain temperature to achieve inactivation of the tumor area. In the current tumor interventional ablation process, ultrasound equipment and ablation equipment need to be placed next to the hospital bed, occupying a large amount of ward space, and the ultrasound system has no special interventional ablation. Process, operational process is complex. In the process of interventional ablation, the clinician needs to take care of the manipulation of the two devices. During the operation, it is necessary to interact with different devices through multiple human interactions, which may lead to misoperation or untimely response. This embodiment designs an ultrasonic interventional ablation system for the above problems, and provides a working method of the system.

The following is a further explanation of an ultrasound interventional ablation system:

As shown in Figure 1, an ultrasound interventional ablation system includes:

The ultrasound imaging module 104 is configured to transmit and receive a specific ultrasonic shape and perform processing to obtain image data of the target tissue.

The interventional ablation module 100 is configured to perform interventional ablation of the target tissue. Preferably, the interventional ablation module 100 includes, but is not limited to, the following devices: an ablation host (a radio frequency ablation device or a microwave ablation device), a cooling system, and a '% melt needle, etc.: '% fusion related device.

The human-computer interaction module 102 is configured to manipulate the ultrasound imaging module 104 and the interventional ablation module 100.

Control and operate.

A typical foot switch has two control buttons for controlling the opening and closing of the ablation module 100 through the switch control button. In order to enhance the control of the interventional ablation module 100, the control of the process can be added to the foot switch, that is, the switch control key is stepped on to indicate that the device is turned on and off, and the step is halfway (not stepping on the bottom) to indicate the interventional ablation. Addition and subtraction control of module 100 power. The power increase/decrease control can be performed each time, and the continuous addition and subtraction control of the power can be formed by the number of times of stepping down or the duration of stepping on the half. The above functions are easily implemented in the industry, and only relevant functions are described herein, and specific implementation details are not described in detail.

Further, the ultrasound interventional ablation system further includes: a control module 108, configured to perform manipulation on the interventional ablation module 100. In addition to the above-described foot switch-based control intervention ablation module 100, preferably, the switch and power of the interventional ablation module 100 can be adjusted based on a button or a knob on the control panel of the ultrasound system, or can be based on an ultrasound imaging module. The touch button of the touch screen of 104 realizes the above function control. The above control of the ablation module can also be achieved by a manual switch comprising a switch button and a slide (or scroll) module. At the same time, the above manual control switch can be attached to the ultrasonic probe as an accessory.

In this embodiment, data transmission between the ultrasound imaging module 104 and the ablation device (ie, the interventional ablation module 100) is performed. The ablation operation parameter is displayed on the ultrasound device (ie, the ultrasound imaging module 104), and the specific display manner is not limited to the above two. The image display module 106 not only supports the state display of one ablation needle, but also supports multiple needles to work simultaneously, and displays the working parameters of different ablation needles.
