Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a safety detection method and device for ablation treatment consumables. Background Art

[0002] Ablation treatment refers to a method of inserting a special ablation catheter into the part to be treated under the guidance of an imaging device, and damaging local tissues by physical or chemical methods to achieve the treatment purpose.

[0003] Ablation methods include thermal ablation and cryoablation. Thermal ablation means generating high temperature locally at the tip of the ablation catheter, similar to installing a small microwave oven in the human body to burn and stimulate tissue necrosis. Cryoablation means releasing gases such as argon and helium at the catheter tip to reach ultra-low temperature, causing the water in tissue cells to crystallize, and then rewarming to cause necrosis.

[0004] During the application of ablation treatment instruments, once they are damaged, it will cause great harm to medical staff and patients. Although the manufacturer will verify and detect the safety and effectiveness of the instruments before leaving the factory, damage still often occurs during actual use. Summary of the Invention

[0049] Since the device in this embodiment has basically the same principle as the foregoing method embodiment, in the above method and device embodiments, the definitions of the same features, calculation methods, listings of implementation manners, and listings of preferred implementation manners can be used interchangeably and will not be repeated here.

[0050] It should be noted that it should be understood that the division of each module of the above device is only a division of logical functions. In actual implementation, it can be fully or partially integrated into a physical entity, or physically separated. These modules can all be implemented in the form of software called by processing elements; they can also all be implemented in the form of hardware; or some modules can be implemented in the form of software called by processing elements, and some modules can be implemented in the form of hardware. For example, the acquisition module can be a separately established processing element, or can be integrated in a certain chip. In addition, it can also be stored in the memory in the form of program code and called and executed by a certain processing element to perform the functions of the above acquisition module. The implementation of other modules is similar. In addition, all or part of these modules can be integrated together or can be independently implemented. The processing element mentioned here can be an integrated circuit with signal processing capabilities. In the implementation process, each step of the above method or each of the above modules can be completed by the integrated logic circuit in the processor element or the instructions in the form of software.

[0051] For example, as Figure 2-1 shown, the device described in the present invention can be integrated into the host 10 for ablation treatment. The host includes an ablation heat source generator. The device is communicatively connected to the ablation heat source generator and extends to the outside to form a pre-inspection key 11, forming the function of one-key pre-inspection. The host can be connected to the catheter 20. The catheter includes a catheter working section 21 (the catheter end is not shown) and a handle 22 that are communicatively connected. The catheter further includes an information memory for storing information such as the catheter model. The information memory is communicatively connected to the device described in the present invention through a signal transmission cable 23. As Figure 2-2 shown, when the catheter 20 is connected to the host, the host reads the stored information in the information memory located inside the catheter through the signal transmission cable 23. After pressing the pre-inspection key 11, the host operates at low power for a short time, and the temperature of the catheter working section 21 begins to rise. During the working time, when the temperature rise amplitude of the catheter reaches the preset value, the host prompts that the catheter is qualified; when the temperature rise of the catheter fails to reach the preset value, the host prompts that the catheter is unqualified (sound and light prompts can be given), and the medical staff needs to replace the catheter and perform the pre-inspection again.

For example: one or more Application Specific Integrated Circuits (ASICs), or, one or more digital signal processors (DSPs), or, one or more Field Programmable Gate Arrays (FPGAs) or Graphics Processing Units (GPUs), etc. Again, when a certain module above is implemented in the form of a processing element scheduler code, the processing element may be a general-purpose processor, such as a Central Processing Unit (CPU) or other processors that can call program code. Again, these modules may be integrated together and implemented in the form of a system-on-a-chip (SOC).

The system bus can be divided into an address bus, a data bus, a control bus, etc. For the sake of simplicity, only a thick line is used to represent it in the figure, but it does not mean that there is only one bus or one type of bus. The communication interface is used to implement the communication between the database access device and other devices (such as clients, read-write libraries, and read-only libraries). The memory may include a Random Access Memory (RAM), and may also include non-volatile memory, such as at least one disk memory.
