[0025] The present disclosure is further described in detail below in conjunction with the accompanying drawings and examples. It is understood that the specific examples described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] The sensor-based measurement method disclosed in the present invention can be used to perform at least one of temperature measurement and pressure measurement in a medical perfusion and aspiration platform (diagnostic and treatment equipment). The medical perfusion and aspiration platform can include equipment such as an endoscope. The medical perfusion and aspiration platform can be used for minimally invasive endoscopic surgery and can be constructed as a kidney stone diagnosis and treatment equipment used in combination with an endoscope and a lithotripsy device.

[0028] Figure 1 It is a schematic flow chart of a sensor-based measurement method according to an embodiment of the present disclosure.

[0029] refer to Figure 1 The sensor-based measurement method M100 of this embodiment includes steps S110 to S150.

[0030] Step S110: acquiring a first ambient temperature of a first environment acquired by a first temperature sensor and a characteristic parameter measurement value of a second temperature sensor at the first ambient temperature.

[0031] The first environment may be the environment of the medical perfusion suction platform, such as an indoor environment. In the present disclosure, the first temperature sensor and the second temperature sensor are preferably different types of temperature sensors. In other words, the two types of temperature sensors measure temperature based on different characteristic parameters.

[0032] For example, the first temperature sensor is an NTC temperature sensor, whose characteristic parameter is resistance value, and the second temperature sensor is an optical fiber Fabry-Perot cavity temperature sensor, whose characteristic parameter is cavity length of Fabry-Perot cavity.

[0033] Inspired by the technical solution of the present disclosure, those skilled in the art can change the types of the first temperature sensor and the second temperature sensor, all of which fall within the scope of the present disclosure. For example, the first temperature sensor can also be a PTC temperature sensor, and the second temperature sensor can be a fiber grating sensor.

[0034] The present disclosure uses two different types of temperature sensors to measure temperature in a first environment (the characteristic parameter measurement value of the second temperature sensor can represent the temperature value), with the purpose of calibrating or compensating the temperature measurement of the second temperature sensor in a second state in the second environment based on the first environment temperature measured by the first temperature sensor and the characteristic parameter measurement value of the second temperature sensor at the first environment temperature.

[0035] S120: Obtain a characteristic parameter measurement value of the second temperature sensor in the second environment in the first state, and determine the temperature of the second environment in the first state based on the characteristic parameter measurement value in the first state.

[0036] The second environment may be a human body cavity, such as a kidney cavity, a stomach cavity, etc. The first state may be an environmental state in which an endoscope is inserted into a target cavity (such as a kidney cavity) and no endoscopic lithotripsy or lithotripsy has been performed. In other words, the first state is a temperature and / or pressure stable state of the target cavity (such as a kidney cavity). The first state and the second state are different environmental states of the second environment.

[0037] In step S120 , the second temperature sensor measures a characteristic parameter measurement value of the second environment in the first state and determines the temperature in the first state based on the characteristic parameter measurement value.

[0038] In the present disclosure, when the second temperature sensor represents the temperature value based on its characteristic parameter measurement value, it can be obtained based on the calibration curve between the calibrated characteristic parameter value and the temperature value. Various temperature sensors are generally calibrated before leaving the factory, and the calibration process is a common technology.

[0039] However, as the environment changes, the temperature measurement of fiber optic Fabry-Perot cavity temperature sensors may deviate or error.

[0040] In step S120, the characteristic parameter measurement value of the second temperature sensor in the first state of the second environment and the temperature determined based thereon, and the characteristic parameter measurement value of the second temperature sensor in the first environment and the temperature determined thereon, conform to the calibration curve described above or have the same degree of acceptable error relative to the above calibration curve.

[0041] The present disclosure constructs data points based on the first ambient temperature measured by the first temperature sensor and the characteristic parameter measurement values ​​of the second temperature sensor at the first ambient temperature. The temperature measurement value of the second temperature sensor can be calibrated or corrected based on the temperature measurement value of the first temperature sensor, see step S130.

[0042] S130. Establish a relationship curve between characteristic parameter measurement values ​​and temperature as a first calibration curve based on the first ambient temperature, the characteristic parameter measurement value of the second temperature sensor at the first ambient temperature, the characteristic parameter measurement value in the first state, and the temperature in the first state.

[0043] It should be noted that the first ambient temperature is measured by the first temperature sensor, rather than determined by the second temperature sensor based on its characteristic parameter measurement value, in order to calibrate or correct the temperature measurement value of the second temperature sensor based on the temperature measurement value of the first temperature sensor.

[0044] Step S130 establishes a first calibration curve based on at least two data points (the first ambient temperature and the characteristic parameter measurement value of the second temperature sensor at the first ambient temperature as one data point, and the characteristic parameter measurement value in the first state and the temperature in the first state as another data point).

[0045] The first calibration curve introduces the measurement accuracy of the first temperature sensor relative to the calibration curve of the second temperature sensor, so that the second temperature sensor obtains more accurate measurement results when measuring the temperature of the second environment, such as the surgical process state (ie, the second state described below).

[0046] S140: Obtain a characteristic parameter measurement value of the second temperature sensor in a second state of the second environment.

[0047] As described above, the second state may be a surgical process state. Since during surgical procedures such as endoscopic lithotripsy, the target cavity (second environment) may be infused with expansion fluid or irradiated with laser, etc., it is necessary to accurately monitor the temperature in the second state in real time to avoid damage to the target cavity.

[0048] S150: Determine the temperature of the second environment in the second state based on the characteristic parameter measurement value in the second state and the first calibration curve.

[0049] Based on the first calibration curve obtained above and the characteristic parameter measurement value of the second temperature sensor in the second state of the second environment, the accurate temperature in the second state can be determined.

[0050] It can be seen that based on the measurement method described above, the second temperature sensor can be calibrated based on the measurement accuracy of the first temperature sensor, so that the temperature measurement result of the second temperature sensor is more accurate.

[0051] The above-described measurement of the first ambient temperature of the first environment using the first temperature sensor can be achieved by taking an average value of multiple measurements, which all fall within the protection scope of the present disclosure.

[0052] Figure 2 It is a flowchart of a sensor-based measurement method according to another embodiment of the present disclosure.

[0053] refer to Figure 2The sensor-based measurement method M200 of this embodiment includes steps S210 to S280. Based on the measurement method M100 described above, the measurement method M200 further includes the following steps: S240, obtaining a characteristic parameter measurement value of the pressure sensor in a second state of the second environment; S260, determining a characteristic parameter calibration amount based on the determined temperature in the second state, the first ambient temperature, and the first calibration curve; S270, compensating a characteristic parameter measurement value of the pressure sensor in the second state of the second environment based on the characteristic parameter calibration amount to obtain a compensated characteristic parameter measurement value; S280. Determine a pressure value corresponding to the compensated characteristic parameter measurement value as the pressure value measured by the pressure sensor in the second state of the second environment.

[0054] In step S240, the measurement of the second temperature sensor and the measurement of the pressure sensor are performed synchronously.

[0055] Accurately obtaining the pressure value of the target cavity during surgery is crucial and affects surgical safety.

[0056] Since the accuracy of fiber optic Fabry-Perot cavity pressure sensors is affected by temperature when measuring pressure, and since the temperature near the front end of the endoscope in the target cavity will change significantly when exposed to laser light during the surgical process, the accuracy of the pressure sensor configured at the front end of the endoscope may be affected.

[0057] Therefore, in this embodiment, first, step S260 determines the characteristic parameter calibration amount for the pressure sensor based on the temperature in the second state determined in step S250, the above-mentioned first ambient temperature (measured by the first temperature sensor) and the above-mentioned first calibration curve, and the characteristic parameter calibration amount characterizes the influence of temperature changes on the characteristic parameter measurement value of the pressure sensor.

[0058] In step S270, the characteristic parameter measurement value (used to characterize the pressure value) of the pressure sensor in the second state is compensated based on the above-mentioned characteristic parameter calibration amount, which can remove the influence of temperature change on the characteristic parameter measurement value of the pressure sensor, thereby obtaining a compensated characteristic parameter measurement value that more accurately characterizes the pressure value.

[0059] Further, in step S280, a more accurate pressure value is obtained based on the pressure value corresponding to the compensated characteristic parameter measurement value as the pressure value measured by the pressure sensor in the second state of the second environment.

[0060] The pressure sensor disclosed in the present invention is preferably a fiber optic Fabry-Perot cavity pressure sensor.

[0061] In a preferred embodiment of the present disclosure, the second temperature sensor and the pressure sensor are both fiber optic Fabry-Perot cavity sensors (fiber optic Fabry-Perot cavity temperature sensor and fiber optic Fabry-Perot cavity pressure sensor), and both may also be resistive sensors (resistive temperature sensor and resistive pressure sensor). Inspired by the technical solution of the present disclosure, those skilled in the art may adjust the types of the second temperature sensor and the pressure sensor, all of which fall within the protection scope of the present disclosure.

[0062] As described above, preferably, the pressure sensor and the second temperature sensor have the same characteristic parameter, which is the length of the Fabry-Perot cavity.

[0063] In some embodiments of the present disclosure, for step S270 described above, determining the characteristic parameter calibration amount based on the determined temperature in the second state, the first ambient temperature, and the first calibration curve includes: The characteristic parameter value corresponding to the temperature in the second state on the first calibration curve is subtracted from the characteristic parameter value corresponding to the first ambient temperature on the first calibration curve to obtain a characteristic parameter difference value as the characteristic parameter calibration amount.

[0064] The characteristic parameter difference is obtained based on the characteristic parameter value corresponding to the first ambient temperature on the first calibration curve because, for the pressure sensor, the existing calibration curve is generally obtained by calibration under normal indoor temperature conditions.

[0065] Based on the above method, the characteristic parameter calibration value of the pressure sensor can be accurately obtained.

[0066] More specifically, for step S270 described above, compensating the characteristic parameter measurement value of the pressure sensor in the second state of the second environment based on the characteristic parameter calibration amount to obtain the compensated characteristic parameter measurement value includes: The characteristic parameter measurement value of the pressure sensor in the second state of the second environment minus the characteristic parameter calibration amount is used as the compensated characteristic parameter measurement value.

[0067] The following is a detailed description of the diagnostic and treatment equipment (eg, a medical perfusion and aspiration platform) provided by the present disclosure.

[0068] Figure 3 It is a schematic block diagram of the structure of a diagnostic and treatment device according to one embodiment of the present invention.
