Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an electric planer and a control method, device and storage medium thereof. Background Art

[0002] An electric planer is a medical device used to remove diseased or excess tissue. When there is no liquid flowing inside the cutter head and the cutter head rotates at high speed, the cutting friction will cause a sharp rise in temperature, causing the plastic parts of the cutter head to melt and stick together.

[0003] In the related art, the temperature of the cutter head is detected by a temperature sensor. When the detected temperature is lower than the set protection value, the cutter head is controlled to operate; when the detected temperature is higher than the set protection value, the cutter head is controlled to stop operating. However, the high-speed rotating cutter head will become sticky in a very short time (about 3-5 seconds). However, since the temperature conduction takes time, the detected temperature has not reached the set protection value at this time, so the cutter head cannot be controlled to stop operating, and therefore, it is impossible to effectively prevent the adhesion of plastic parts in the electric planer.

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The following describes an electric planer and a control method, device and storage medium thereof provided by an embodiment of the present invention with reference to the accompanying drawings.

[0031] Figure 1 is a flow chart of a control method for an electric planer according to an embodiment of the present invention, referring to Figure 1 As shown, the control method of the electric planer may include the following steps:

[0032] Step S101: when the control motor drives the cutter head to rotate, the liquid flow state inside the cutter head is obtained.

[0033] It should be noted that in the removal of skin, muscle, ligament, bone and other tissues, an electric planer is needed to remove diseased or redundant tissue. Figure 2 is a schematic diagram of the structure of an electric planer in a specific example, Figure 3 for Figure 2 For a partial enlarged view, see Figure 2 and Figure 3 As shown, 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 excess tissue, and the motor 203 is used to drive the cutter head 201 to rotate. At the same time, the electric planer 200 is also provided with a liquid channel 204 for liquid to flow through the inside of the cutter head.

[0034] It should be understood that the present application does not impose any specific restrictions on the arrangement of the liquid channel, as long as the liquid can flow through the inside of the blade. Specifically, the liquid channel can be located at one end of the blade body (such as the handle end of the blade body) and at the other end of the blade head (such as the working end of the blade head), one of the two ends is the liquid inlet end, and the other is the liquid outlet end, so that the liquid channel can be used to inject liquid into or extract liquid from the patient. For example, during surgery, physiological saline can be injected into the patient through the liquid channel, and physiological saline, tissue waste fluid or other liquid can also be extracted from the patient through the liquid channel. In addition, the liquid channel can also be a channel path passing through the inside of the blade head, and its liquid inlet end and liquid outlet end are both located at the blade body (such as the handle end of the blade body), so that the liquid can flow from the liquid inlet end of the blade body into the inside of the blade head, and then flow out from the liquid outlet end of the blade body. For example, during bone drilling surgery, water or other coolants can be circulated through the liquid channel to cool the blade head to prevent thermal damage caused by frictional heat generation.

[0035] Specifically, for different clinical needs, when using an electric planer, it may be necessary to turn on the fluid flow, or it may not be necessary. It may be necessary to turn on the fluid flow at some stages of the operation and turn it off at other stages. For example, the blade head may be turned on at the beginning of the operation, and only after the blade head is positioned at the patient's site is the fluid flow turned on to extract or inject physiological saline.

[0036] When the cutter head rotates at high speed, the cutting friction will generate heat rapidly. If there is no liquid passing through the liquid channel at this time, the temperature of the cutter head will rise sharply. If it continues to run, it will cause the plastic parts of the cutter head (such as Figure 2 and Figure 3 The plastic inner sleeve 205 and the plastic outer sleeve 206 shown in the figure melt and stick together; on the contrary, if there is liquid passing through the liquid channel inside the cutter head, since the liquid is usually water, physiological saline or other solution, it has a large specific heat capacity and can absorb a large amount of heat, which can effectively prevent the cutter head from overheating. It can be seen that the liquid flow state is an important factor affecting the temperature of the cutter head. Therefore, when the control motor drives the cutter head to rotate, the liquid flow state inside the cutter head is first obtained, and the liquid flow state is used as the basis for subsequent different control methods.

[0037] Furthermore, 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.

[0038] That is to say, the liquid flow state can be reflected by the humidity information inside the cutter head. Specifically, the 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 flow state can be determined based on the humidity information. It should be understood that regarding the liquid flow state inside the cutter head, the present application is not limited to obtaining it through sensors, etc. For example, the electric planer can be equipped with a liquid extraction device (such as a negative pressure aspirator) to drive the extraction, injection or circulation of the liquid in the channel. In this case, the electric planer can be communicatively connected to the liquid extraction device to obtain relevant data information (such as pressure or flow, etc.) of the liquid extraction device, and the liquid flow state inside the cutter head can be obtained based on the data information.

[0039] Optionally, the humidity information inside the cutter head is acquired through a sensor, and the sensor is arranged in the liquid channel.

[0040] Specifically, the sensor may include a humidity sensor, a water immersion sensor, a flow sensor, a liquid level sensor, etc. If a humidity sensor is used to obtain humidity information inside the cutter head, refer to Figure 3 As shown, the humidity sensor 207 can be positioned on the inner wall of the liquid channel 204 so that the probe of the humidity sensor 207 is located in the liquid channel 204, and the humidity sensor 207 is preferably set close to the cutter head 201 to improve the accuracy of the detection. If a 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. For a liquid channel that is partly a pipe structure and partly a cavity structure, it is preferred to set the flow sensor at the pipe structure of the liquid channel. For the water immersion sensor and the liquid level sensor, the setting method is similar to that of the humidity sensor and the flow sensor, and will not be described in detail here.

[0041] Step S102: If there is no liquid flowing inside the cutter head, the motor is controlled to drive the cutter head to rotate according to a first speed, wherein the first speed is a smaller value between the target required speed and the maximum allowable speed, and the maximum allowable speed is the maximum speed when there is no liquid flowing inside the cutter head and the cutter head is not adhered.

[0042] That is to say, when the blade is rotating, if it is detected that no liquid is passed into the inside of the blade, if the set speed of the blade is expressed as the target required speed Rset (this speed can be input according to clinical needs), and the maximum speed when there is no liquid in the blade and the blade is not adhered is expressed as the maximum allowable speed Rsafety (this speed can be determined based on experimental research or experience), then when the target required speed Rset ≤ the maximum allowable speed Rsafety, the motor is controlled to drive the blade to rotate according to the target required speed Rset; when the target required speed Rset > the maximum allowable speed Rsafety, the motor is controlled to drive the blade to rotate according to the maximum allowable speed Rsafety. That is, when the set speed of the blade is higher than the maximum allowable speed Rsafety, the blade is controlled to reduce the speed, and the speed is reduced to the maximum allowable speed Rsafety, so as to ensure that the speed of the blade is not higher than the maximum allowable speed Rsafety, thereby effectively preventing adhesion caused by high-speed rotation of the blade.

[0043] On the contrary, if there is liquid inside the blade head, the motor is controlled to drive the blade head to rotate according to the target required speed Rset. That is to say, during the rotation of the blade head, when it is detected that there is liquid inside the blade head, since the liquid can absorb a lot of heat, it can effectively prevent the blade head from overheating and will not cause the blade head to stick. Therefore, no additional adjustment is required. It is only necessary to control the blade head to rotate according to the target required speed Rset according to clinical needs.

[0044] It can be seen that when the control motor drives the cutter head to rotate, the liquid flow state inside the cutter head is obtained. If no liquid is passed into the cutter head, the motor is controlled to drive the cutter head to rotate according to the first speed, wherein the first speed is the smaller value between the target required speed and the maximum allowable speed, and the maximum allowable speed is the maximum speed when there is no liquid flowing into the cutter head and the cutter head is not adhered. Therefore, on the one hand, it can ensure that the speed of the cutter head is not higher than the maximum allowable speed, thereby effectively solving the adhesion problem caused by the high-speed rotation of the cutter head; on the other hand, compared with the control method of only detecting the temperature of the cutter head and controlling the cutter head to stop running once the temperature of the cutter head is higher than the set protection value, it can effectively reduce the frequency of interruption of the cutter head operation and have good operation continuity.

[0045] 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.

[0046] That is to say, when solving the adhesion problem caused by high-speed rotation of the cutter head, the motor can be controlled not only according to the liquid flow state inside the cutter head, but also according to the temperature information of the cutter head to achieve double protection, thereby further preventing the cutter head from sticking.

[0047] It should be understood that the control of the motor according to the temperature information can be the control of the start and stop state of the motor, or the control of the motor speed, and this application does not impose specific restrictions on this. It should also be understood that the control of the motor according to the temperature information can be throughout the entire process of the rotation of the cutter head, that is, from the beginning of the motor controlling the cutter head to the motor controlling the cutter head to stop rotating, or it can be at a certain stage of the rotation of the cutter head, such as the stage of controlling the motor to drive the cutter head to rotate according to the first speed, such as the stage after the cutter head speed exceeds a certain set threshold, and the stage after judging that the cutter head is liquid-passing, etc., and this application does not impose specific restrictions on this.

[0048] Optionally, the motor is controlled according to the temperature information, including: if the temperature information is greater than or equal to a preset temperature threshold, the motor is controlled to stop working, wherein the preset temperature threshold is the minimum temperature when the cutter head becomes stuck.

[0049] In other words, the lowest temperature inside the cutter head when the cutter head is stuck 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 there is a risk of adhesion of the cutter head. At this time, the motor is controlled to stop driving the cutter head to rotate. After that, after a certain period of cooling, the motor can be restarted and controlled by the above-mentioned fluid flow status and temperature information.

[0050] Furthermore, the temperature information of the cutter head can be obtained through the temperature sensor, refer to Figure 3 As shown, the temperature sensor 208 is disposed close to the cutter head 201 , and the temperature sensor 208 includes a probe for detecting temperature, and the probe is isolated from the liquid channel 204 .

[0051] Specifically, when the temperature information of the cutter head is obtained through the temperature sensor 208, the temperature sensor 208 can be set close to the cutter head 201, and preferably the temperature sensor 208 can be set close to the working end of the cutter head 201 to shorten the temperature conduction time and 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 to prevent the probe of the temperature sensor from being exposed to the liquid channel and affected by liquid infiltration, thereby reducing the accuracy of the detection results and the life of the temperature sensor.

[0052] Figure 4 is a flow chart of a control method for an electric planer according to a specific embodiment of the present invention, referring to Figure 4 As shown, the control method of the electric planer may include the following steps:

[0053] Step S301: when the control motor drives the cutter head to rotate, the liquid flow state inside the cutter head is obtained.

[0054] For example, the humidity information inside the cutter head is obtained through a humidity sensor, and the liquid flow state inside the cutter head is obtained based on the humidity information.

[0055] Step S302: If there is no liquid flowing inside the cutter head, determine whether the target required speed Rset ≤ the maximum allowable speed Rsafety. 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 drive the cutter head to rotate with the maximum allowable speed Rsafety as the first speed. If there is liquid flowing inside the cutter head, the motor is controlled to drive the cutter head to rotate with the target required speed Rset.

[0056] Step S303: Obtain the temperature information of the cutter head through the temperature sensor to determine whether the temperature information satisfies the preset temperature threshold. If so, the cutter head is controlled to stop running; if not, step S301 is executed, that is, the liquid flow state inside the cutter head is continuously obtained.

[0057] In summary, according to the control method of the electric planer of 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 to drive the cutter head to rotate according to the first speed, wherein the first speed is the smaller value between the target required speed and the maximum allowable speed, and the maximum allowable speed is the maximum speed when there is no liquid flow inside the cutter head and the cutter head is not adhered. In this way, the adhesion problem caused by the high-speed rotation of the cutter head can be effectively solved, and the operation continuity is good, and it is not easy to have frequent interruptions in operation.
