Based on the unified inventive concept, an embodiment of the present invention further provides a heating control method applied to the above therapeutic apparatus, the flow of which is shown in fig. 20, and the method includes the following steps:

s101: and acquiring the real-time temperature of the treatment probe in the treatment appliance.

After the control chip detects that the therapeutic appliance is connected to the host, the control chip can be connected with the therapeutic appliance through the cable interface on the host, and the real-time temperature of the therapeutic probe on the therapeutic appliance is obtained through the connecting cable.

Optionally, after the therapeutic apparatus is connected to the host, the control chip may identify a type of the therapeutic probe on the therapeutic apparatus, and configure the heating control algorithm parameter according to the type of the therapeutic probe. The control chip can determine the model of the treatment probe according to the resistance value of the identification resistor arranged in the connecting rod of the treatment appliance.

S102: and judging whether the real-time temperature of the treatment probe reaches the set target temperature. If not, executing step S103; if yes, go to step S104.

The target temperature for heating the treatment probe can be set through the temperature adjusting module on the host machine, so that the working temperature of the treatment probe can be better controlled, and the stability of the working temperature is ensured.

S103: and controlling a heating sheet in the therapeutic appliance to heat the therapeutic probe until the target temperature is reached according to the real-time temperature of the therapeutic probe and the set target temperature.

In the step, the heating condition of the treatment probe is controlled according to the real-time temperature of the treatment probe and the set target temperature, and different temperature control algorithms can be adopted for the treatment probes with different models, or the same temperature control algorithm is adopted and different algorithm parameters are configured.

In some alternative embodiments, the temperature difference between the set target temperature and the real-time temperature of the treatment probe may be determined; and determining the heating speed for heating the heatable treatment head according to the temperature difference, and controlling the heating sheet in the therapeutic appliance to heat the heatable treatment head until the target temperature is reached based on the determined heating speed.

When the heating speed is determined based on the temperature difference, if the temperature difference between the set target temperature and the real-time temperature of the treatment probe is greater than a set first temperature threshold, determining that the treatment probe is heated at a first heating speed; if the temperature difference between the set target temperature and the real-time temperature of the treatment probe is not greater than the set first temperature threshold, determining that the treatment probe is heated at a second heating speed; the second heating rate is less than the first heating rate.

S104: the heating was stopped.

A specific implementation flow of the heating control method is shown in fig. 12, and includes the following steps:

s201: it is detected that the therapeutic appliance is connected to the host.

After the power switch of the host computer is turned on, the control chip starts to work and detects whether the therapeutic apparatus is connected to the host computer in real time. When the therapeutic device is connected to the host computer through the cable, the control chip can detect the therapeutic device.

S202: and judging whether the connection between the therapeutic equipment and the host computer is abnormal or not. If yes, go to step S203; if not, go to step S204.

S203: and prompting the user.

When the abnormality exists, the user can be prompted through the display or the state indicating lamp, the user can also be prompted through the buzzer alarm, the user is waited to check the abnormal condition, and the control chip continues to monitor the connection state of the therapeutic apparatus and the host.

S204: and acquiring a preset target temperature.

The control chip obtains the target temperature set by the temperature adjusting module. For example: a user can preset a target temperature value through a temperature adjusting knob on a host panel, and the control chip can acquire the target temperature value.

S205: a real-time temperature of a treatment probe in a treatment appliance is acquired.

S206: and judging whether the temperature difference between the set target temperature and the real-time temperature of the treatment probe is not greater than a set first temperature threshold value. If not, go to step S207; if yes, go to step S208.

For example, the first temperature threshold may be set to 5 ℃ or 10 ℃ or other values as desired.

S207: it is determined that the treatment probe is to be heated with the first heating rate.

S208: determining to heat the treatment probe with the second heating rate. The second heating rate is less than the first heating rate.

That is to say, when the temperature heating control is performed through the PID temperature control algorithm preset by the control chip, after the target temperature is preset, when the treatment probe is just started to be heated, the treatment probe can be quickly heated due to the large difference between the temperature and the target temperature, and when the distance between the treatment probe and the target temperature is relatively close, for example, when the temperature difference between the treatment probe and the target temperature is only 5 ℃, the treatment probe is slowly heated and enters the fine adjustment until the preset temperature is reached.

S209: and judging whether the real-time temperature of the treatment probe reaches the target temperature. If not, returning to continue executing the step S206; if yes, go to step S210.

S210: and monitoring the real-time temperature change condition of the treatment probe, and controlling a heating sheet in the treatment appliance to heat the treatment probe until the real-time temperature of the treatment probe is lower than the set target temperature and the temperature difference value is greater than a second temperature threshold value until the target temperature is recovered.

In the treatment process, the treatment probe can contact cervical tissue, the treatment probe transfers heat to the cervical tissue to cause the temperature of the treatment probe to start to fall, the control chip detects the temperature change of the treatment probe at the moment, when the temperature change reaches a certain value, the treatment probe is continuously heated to ensure that the temperature of the treatment probe is maintained at the target temperature or the distance between the treatment probe and the target temperature does not exceed a set second temperature threshold value, and the temperature is ensured to be constant in the treatment process.

After the treatment probe reaches the preset target temperature, the user can operate the treatment appliance to treat the patient. The user stretches into the working channel that the vaginal speculum was peeied into to the metal duckbilled with therapeutic apparatus, presses close to cervical lesion region with the treatment probe, treats after the treatment, takes out therapeutic apparatus.

During treatment, the coagulation depth during treatment can be determined according to the depth of the lesion tissue, and the treatment time can be determined according to the coagulation depth and the set target temperature. Because the temperature of the treatment probe, the acting time and the solidification depth during treatment can form a certain dose-effect relationship, a dose-effect relationship model among the solidification depth, the temperature parameter and the treatment time can be established in advance, and after the solidification depth and the set target temperature are determined, the treatment time, namely the acting time of the treatment probe on the pathological change tissue, can be determined according to the dose-effect relationship model; at the same temperature, the action time is prolonged, and the solidification depth is deepened; the same action time, the higher the temperature is, the deeper the solidification depth is; therefore, the same depth of solidification can be obtained depending on the temperature and the action time. Therefore, the accurate treatment scheme is preset according to parameters such as the disease type, the pathological change degree and the cervical pathological change tissue depth of the patient, and the accurate solidification and the accurate treatment which are targeted in real time are realized according to different required solidification depths of different diseases of different patients.

When the treatment is carried out, the position of the treatment probe can be detected, when the treatment probe is detected to reach the designated treatment position, the treatment is timed, and when the duration of the treatment timing reaches the determined treatment time, the treatment is ended.

The heating control method can accurately control the temperature of the treatment probe through the control chip, can accurately control the heating temperature and the heating time before the target temperature is reached, can keep constant temperature after the target temperature is reached, and is crucial in the whole treatment process and is a key factor for ensuring the treatment effect, the heating temperature can be controlled between 50 ℃ and 120 ℃, and the temperature control accuracy can reach +/-3 ℃. For the disease with high temperature requirement, the temperature control precision can reach +/-1 ℃.
