Description

Electrode consumable interaction method, calcified plaque medical equipment and readable storage medium

Technical Field

The application relates to the technical field of calcified plaque medical equipment, in particular to an electrode consumable interaction method, calcified plaque medical equipment and a readable storage medium.

Background

With the age-related age of the social population, the incidence of calcification-related vascular diseases has also increased year by year. Vascular calcification is manifested by abnormal deposition of excessive calcium and phosphorus in the wall of large vessels such as coronary artery and peripheral artery, resulting in decreased elasticity of artery, stenosis of lumen, increased vulnerability of atherosclerotic plaque, and induction of acute cardiovascular events. Complications associated with vascular calcification pose a serious threat to the health of patients, and in patients with coronary heart disease (CAD), the pathological course of coronary calcification suggests the occurrence and progression of coronary heart disease. In the united states, over 900 million people are afflicted with peripheral vascular disease each year, and 30-50% of patients have varying degrees of calcified lesions in their vascular walls. When peripheral blood vessels of lower limbs (such as femoral artery, anterior tibial artery and the like) are seriously calcified, the blood supply of the lower limbs is insufficient, and the pain of the legs of a patient is caused to influence normal walking. Patients with serious illness need surgical treatment or even amputation, and heavy burden is brought to the patients and medical systems. It follows that the hazards of calcification of the cardiovascular system are not inconsequential, and how to better address the problem of calcification will further improve the therapeutic level of cardiovascular calcified diseases.

Currently, the main treatment means for vascular calcification are medical treatment and surgical treatment. The internal treatment is to stabilize the plaque in the blood vessel by using lipid regulating drugs, slow down the progress of atherosclerosis, or regulate the whole calcium-phosphorus metabolism by using calcium-phosphorus balance regulators such as phosphate binders, diphosphates and the like, and reduce the calcium salt deposition and calcium crystal nucleation; however, the effect of these drugs on vascular calcification is not clear and patients with advanced vascular calcification are less effective. The surgical treatment method comprises intervention treatment and artery bypass transplantation. The interventional device has traditional saccule, special saccule and percutaneous atherectomy, and these devices and techniques have many limitations and are easy to cause serious complications. The traditional balloon has a good expansion effect only on soft lesions, but in the aspect of treating calcified lesion blood vessels, higher pressure is needed to restore the lumen again, and continuous high pressure is easy to cause secondary mechanical injury of the blood vessels and even rupture of the blood vessels. Special balloons, such as embedded balloons and spinous process balloons have special use conditions, and require long-time training of operators. Atherectomy devices are expensive, complex to operate, long in operation time, and difficult to solve the problems of distal embolization and high risk of vascular injury. In order to solve the problems in calcified blood vessel treatment, ultrasonic lithotripsy and balloon angioplasty technologies are combined, and the calcified artery disease is treated by sound waves, so that the defects of the traditional equipment and technology in the treatment process can be overcome better, and the calcified artery disease treatment method is expected to become a new generation calcified blood vessel treatment technology.

The main body equipment of the medical equipment for treating the artery calcified plaque comprises consumable electrodes, connecting wires and a high-voltage generator. Because of the difference of patient's pathology, the consumptive material also has multiple specification, to different affected parts, needs to use different consumptive materials, and high pressure generator treatment output configuration also has difference. Before treatment, consumables suitable for patients are required to be connected with a high-voltage generator through a connector, and then an output matched with the consumables is configured on the high-voltage generator. Identifying the specification information pasted on the consumable by an operator under the normal condition to confirm the model of the consumable, then setting the parameters of the high-voltage generator, and treating the patient after the setting is finished. The consumptive material passes through personnel and discerns, and the mistake can be appeared in the inevitable, if the configuration is used for the treatment with the inconsistent parameter information of consumptive material electrode, probably arouses unpredictable's consequence, has certain safety risk. And the state of the consumable can not be monitored in real time in the using process, and the response can not be timely carried out when abnormity occurs, so that the output is closed.

The foregoing description is provided for general background information and is not admitted to be prior art.

The application also provides an electrode consumable interaction method of the calcified plaque medical equipment, and fig. 3 is a flow chart of the electrode consumable interaction method of the calcified plaque medical equipment in an embodiment of the application.

The electrode consumable interaction method shown in fig. 3 can be applied to the calcified plaque medical apparatus shown in fig. 1 or fig. 2, and in one embodiment, the electrode consumable interaction method includes:

s10: the equipment end sends a consumable model inquiry command to the consumable end through the connector.

The equipment end can communicate with the consumable end according to a preset communication protocol after the consumable end is normally connected. When the model information of the consumable end is needed, the equipment end can send a model inquiry command to obtain the model information. Specifically, in one embodiment, the step of S10 is preceded by: the equipment end outputs a power supply signal to the consumable end through the connector after being electrified; the equipment end inquires the level state of a monitoring signal port of the consumable end; when the equipment end keeps high level in the level state within the first preset time, judging that the power supply of the consumable end is normally connected, and entering the step S10; and when the monitoring signal does not keep high level within the first preset time, the equipment end judges that the communication is abnormal.

S20: the consumable end feeds back consumable model information through the connector.

After the model inquiry command is received, the consumable part end feeds back consumable part model information, and the equipment end can accurately determine the accessed consumable part model. Therefore, the medical equipment can automatically identify consumables, and the subsequent medical implementation process can be ensured to be safe and reliable.

S30: the equipment end receives the consumable model information through the connector, and after the consumable model of the consumable end is extracted, the output parameters of the high-voltage generator are configured according to the consumable model.

In an embodiment, the output parameter comprises at least one of a maximum number of drives, a discharge duration, a discharge voltage.

The consumable end is driven by the high-voltage pulse to perform corresponding medical action on the calcified plaque. The equipment end collects the detected actual treatment information through the sensing device and sends the information to the consumable end. The consumable end and the equipment end record treatment data, and the full life cycle management of the equipment can be realized on the basis.

Wherein "0102030405" is consumable type of 5 bytes, the next "0001" is consumable driving times of 2 bytes, "0506" is discharge actual voltage of 2 bytes, and "0A 0B" is discharge actual time of 2 bytes. In other embodiments, one or more necessary data items may be selected for storage, and different data items may have other byte numbers to adapt to different storage requirements.

In one embodiment, the step of S10 is preceded by:

the consumable code domain is 5 bytes;

the command word field is 1 byte;

the data direction field is 1 byte;

the data check field is 2 bytes;

The number of bytes occupied by the specific field in each frame of data is specified, so that the equipment end and the consumable end can successfully identify and analyze the received data frame.

Fig. 4 is a schematic flowchart illustrating a communication abnormality determination method in an electrode consumable interaction method according to an embodiment of the present disclosure. As shown in fig. 4, the communication abnormality determination method includes the following steps:
