technical field

The invention relates to the technical field of medical devices, in particular to an electric planer and its control method, device and storage medium.

Background technique

The electric planer is a medical device used to remove diseased tissue or excess tissue. When there is no liquid inside the cutter head, when the cutter head rotates at high speed, the cutting friction will cause the temperature to rise sharply, causing the plastic parts of the cutter head to melt and glued together.

detailed description

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

The electric planer and its control method, device and storage medium provided by the embodiments of the present invention are described below with reference to the accompanying drawings.

Fig. 1 is the flow chart of the control method of electric planer according to one embodiment of the present invention, with reference to shown in Fig. 1, the control method of this electric planer may comprise the following steps:

Step S101 : when the motor is controlled to drive the cutter head to rotate, acquire the fluid flow state inside the cutter head.

It should be noted that in the excision of various tissues such as skin, muscle, ligament, bone, etc., it is necessary to use an electric planer to remove diseased or redundant tissues. Figure 2 is a schematic structural diagram of the electric planer in a specific example, and Figure 3 is a diagram 2, as shown in Figure 2 and Figure 3, the electric planer 200 includes a cutter head 201 and a blade body 202, and the blade body 202 includes a motor 203, wherein the cutter head 201 is used to cut diseased tissue or redundant tissue, and the motor 203 is used to Drive the cutter head 201 to rotate, and at the same time, the electric planer 200 is also provided with a liquid channel 204 for the liquid to flow through the cutter head.

It should be understood that the present application does not impose specific limitations on the arrangement of the liquid channels, as long as the liquid can flow through the interior of the cutter head. Specifically, one end of the liquid passage can be located at the blade body (such as the handle end of the blade body), and the other end is positioned at the cutter head (such as the working end of the cutter head), one of the two ends is a liquid inlet end, and the other is a liquid outlet end, so that the fluid channel can be used to inject fluid into the patient or extract fluid. For example, during an operation, physiological saline solution can be injected into the patient through the liquid channel, and physiological saline solution, tissue waste fluid or other liquids can also be extracted from the patient through the liquid channel. In addition, the liquid channel can also be that the channel path passes through the inside of the cutter head, and its liquid inlet and outlet ends are all located at the blade body (such as the handle end of the blade body), so that the liquid can flow into the cutter head from the liquid inlet end of the blade body, and then Flow out from the liquid outlet of the cutter body, for example, during the bone drilling operation, water or other cooling liquid can be circulated through the liquid channel to cool the cutter head, so as to prevent thermal damage caused by frictional heat.

Specifically, for different clinical needs, when using an electric planer, it may be necessary to turn on the liquid flow, or it may not be necessary to turn on the liquid flow, or it may be that the liquid flow needs to be turned on in some stages during the operation, and it needs to be turned off in some stages. , For example, in the early stage of the operation, the cutter head is turned on to rotate, and after the cutter head is positioned on the diseased part, the liquid is opened to extract or inject physiological saline.

When the cutter head rotates at high speed, the cutting friction will generate heat rapidly. At this time, if there is no liquid passing through the liquid channel, the temperature of the cutter head will rise sharply. If it continues to run, it will cause the plastic parts of the cutter head (as shown in Figure 2 and the plastic inner sleeve 205 and the plastic outer sleeve 206 shown in Fig. 3) melt and stick together; On the contrary, if there is liquid to pass in the liquid channel inside the cutter head, since the liquid is usually water, physiological saline Or other solutions have a large specific heat capacity, can absorb a large amount of heat, and can effectively prevent the temperature of the cutter head from being too high. It can be seen that the liquid state is an important factor affecting the temperature of the cutter head. Therefore, when the motor is controlled to drive the cutter head to rotate, the liquid flow state inside the cutter head is obtained first, and the liquid flow state is used as the basis for subsequent adoption of different control methods.

Further, obtaining the liquid flow state inside the cutter head includes: obtaining humidity information inside the cutter head; and obtaining the liquid flow state inside the cutter head according to the humidity information.

That is to say, the state of liquid flow can be reflected by the humidity information inside the cutter head. Specifically, humidity information inside the cutter head can be detected by sensors such as humidity sensors, water immersion sensors, flow sensors, and liquid level sensors, and the liquid-passing state can be determined according to the humidity information. It should be understood that the present application is not limited to obtaining the liquid state inside the cutter head through sensors, etc. In this case, the electric planer can be communicated with the pumping device to obtain relevant data information (such as pressure or flow, etc.) of the pumping device, and obtain the liquid state inside the cutter head according to the data information.

Optionally, the humidity information inside the cutter head is acquired through a sensor, and the sensor is arranged in the liquid channel.

Specifically, the sensors may include humidity sensors, water immersion sensors, flow sensors, liquid level sensors, and the like. If a humidity sensor is used to obtain the humidity information inside the cutter head, as shown in Figure 3, the humidity sensor 207 can be positioned on the inwall of the liquid passage 204, so that the probe of the humidity sensor 207 is positioned in the liquid passage 204, and preferably the humidity sensor 207 is set close to the cutter head 201 to improve the accuracy of detection. If the flow sensor is used to obtain the humidity information inside the cutter head, the flow sensor can be positioned on the inner wall of the liquid channel so that the probe of the flow sensor is located in the liquid channel. That said, the flow sensor is preferably arranged at the pipe structure of the liquid passage. For the water immersion sensor and liquid level sensor, the setting method is similar to that of the humidity sensor and flow sensor, and will not be detailed here.

Step S102: If the inside of the cutter head is not connected with liquid, then control the motor to drive the cutter head to rotate according to the first rotational speed, wherein the first rotational speed is the smaller value between the target required rotational speed and the maximum allowable rotational speed, and the maximum allowable rotational speed is the maximum allowable rotational speed of the cutter head. The maximum speed when the liquid is flowing and the cutter head is not sticking.

That is to say, when the cutter head rotates, when it is detected that there is no liquid inside the cutter head, if the set speed of the cutter head is expressed as the target required speed Rset (this speed can be input according to clinical needs), the cutter head The maximum speed when the interior is not connected to liquid and the cutter head is not stuck is expressed as the maximum allowable speed Rsafety (this speed can be determined according to experimental research or experience), then when the target demand speed Rset≤ the maximum allowable speed Rsafety, according to the target demand speed Rset controls the motor to drive the cutter head to rotate; when the target demand speed Rset>the maximum allowable speed Rsafety, the motor is controlled to drive the cutter head to rotate according to the maximum allowable speed Rsafety. That is, when the set speed of the cutter head is higher than the maximum allowable speed Rsafety, the cutter head is controlled to reduce the speed to run, and the speed is reduced to the maximum allowable speed Rsafety, so as to ensure that the speed of the cutter head is not higher than the maximum allowable speed Rsafety, thereby It can effectively prevent the sticking caused by the high-speed rotation of the cutter head.

On the contrary, if there is liquid inside the cutter head, the motor is controlled according to the target required speed Rset to drive the cutter head to rotate. That is to say, during the rotation of the cutter head, when it is detected that there is liquid flowing inside the cutter head, since the liquid can absorb a large amount of heat, it can effectively prevent the temperature of the cutter head from being too high, and will not cause the occurrence of the problem of cutter head sticking. Therefore, there is no need to make additional adjustments, it is only necessary to control the rotation of the cutter head according to the target speed Rset according to the clinical needs.

It can be seen that, when the motor is controlled to drive the cutter head to rotate, the liquid state inside the cutter head is obtained. If the inside of the cutter head is not filled with liquid, the motor is controlled to drive the cutter head to rotate according to the first rotational speed, wherein the first rotational speed is the target The smaller value of the required speed and the maximum allowable speed. The maximum allowable speed is the maximum speed when the inside of the cutter head is not connected to liquid and the cutter head is not stuck. Therefore, on the one hand, it can ensure that the rotation speed of the cutter head is not higher than the maximum allowable rotation speed, thereby effectively solving the sticking problem caused by the high-speed rotation of the cutter head; Once it is higher than the set protection value, the control method of controlling the cutting head to stop running can effectively reduce the frequency of cutting head operation interruption, and the operation continuity is good.

In one embodiment, when controlling the motor to drive the cutter head to rotate, the method further includes: acquiring temperature information of the cutter head; and controlling the motor according to the temperature information.

That is to say, when solving the sticking problem caused by the high-speed rotation of the cutter head, not only the motor can be controlled according to the liquid state inside the cutter head, but also the motor can be controlled according to the temperature information of the cutter head to achieve double protection , so as to further prevent the head from sticking.

It should be understood that the control of the motor according to the temperature information may be the control of the start-stop state of the motor, or the control of the speed of the motor, which is not specifically limited in this application. It should also be understood that the control of the motor according to the temperature information can be carried out throughout the entire process of the rotation of the cutter head, that is, from the time the motor controls the rotation of the cutter head until the motor controls the rotation of the cutter head, or it can be at a certain point during the rotation of the cutter head. A stage, such as the stage of controlling the motor according to the first rotating speed to drive the cutter head to rotate, such as the stage after the rotating speed of the cutter head exceeds a certain set threshold, and the stage after judging the internal liquid flow of the cutter head, etc., the application does not make any comment on this. Specific restrictions.

Optionally, controlling the motor according to the temperature information includes: if the temperature information is greater than or equal to a preset temperature threshold, controlling the motor to stop working, wherein the preset temperature threshold is the minimum temperature when the cutter head sticks.

That is to say, the lowest temperature inside the cutter head when the cutter head sticks can be determined through experimental research or experience, and this temperature value can be used as the preset temperature threshold. During the rotation of the cutter head, the actual temperature of the cutter head can be obtained in real time. When the actual temperature is greater than or equal to the above preset temperature threshold, it means that the cutter head has a risk of sticking. At this time, the control motor stops driving the cutter head to rotate. Afterwards, after cooling down for a certain period of time, the motor can be restarted, and the motor can be controlled through the above-mentioned fluid state and temperature information.

Further, the temperature information of the cutter head can be acquired through a temperature sensor. As shown in FIG.

Specifically, when the temperature information of the cutter head is obtained by the temperature sensor 208, the temperature sensor 208 can be arranged close to the cutter head 201, and preferably the temperature sensor 208 is arranged close to the working end of the cutter head 201 to shorten the temperature conduction time , to obtain more accurate real-time temperature information, thereby improving the reliability of the control method for preventing adhesion; and, the probe of the temperature sensor 208 can be isolated from the liquid channel 204, so as to prevent the probe of the temperature sensor from being exposed in the liquid channel, Affected by liquid infiltration, the accuracy of detection results and the life of the temperature sensor will be reduced.

Fig. 4 is the flow chart of the control method of electric planer according to a specific embodiment of the present invention, with reference to shown in Fig. 4, the control method of this electric planer may comprise the following steps:

Step S301: Acquiring the fluid flow state inside the cutter head when the motor drives the cutter head to rotate.

For example, the humidity information inside the cutter head is obtained through the humidity sensor, and the liquid flow state inside the cutter head is obtained according to the humidity information.

Step S302: If the inside of the cutter head is not connected with liquid, it is judged whether the target required rotational speed Rset≤the maximum allowable rotational speed Rsafety is satisfied. If so, the motor is controlled to drive the cutter head to rotate with the target required speed Rset as the first speed; if not, the motor is controlled to rotate with the maximum allowable speed Rsafety as the first speed. If the inside of the cutter head is filled with fluid, the motor is controlled at the target required speed Rset to drive the cutter head to rotate.

Step S303: Obtain the temperature information of the cutter head through the temperature sensor, and determine whether the temperature information ≥ a preset temperature threshold is satisfied. If yes, control the cutter head to stop running; if not, execute step S301, that is, continue to obtain the fluid flow state inside the cutter head.

To sum up, according to the control method of the electric planer according to the embodiment of the present invention, when the motor is controlled to drive the cutter head to rotate, the liquid flow state inside the cutter head is obtained. If there is no liquid flow inside the cutter head, the motor is controlled according to the first rotational speed. Drive the cutter head to rotate, wherein the first rotational speed is the smaller value of the target required rotational speed and the maximum allowable rotational speed, and the maximum allowable rotational speed is the maximum rotational speed when the interior of the cutter head is not connected with liquid and the cutter head is not stuck. This can effectively solve the sticking problem caused by the high-speed rotation of the cutter head, and the operation continuity is good, and the frequent interruption of operation is not easy to occur.
