Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to an endoscope with temperature and pressure measurement functions and a liquid injection control method thereof. Background Art

[0002] There are many kinds of existing endoscopes, but when injecting liquid into the body, existing endoscopes only play the function of observation, diagnosis, treatment or liquid delivery, and the amount of liquid injected and the injection pressure are completely determined and adjusted by the operator's experience, which will cause great safety hazards.

[0003] Moreover, some endoscopes with temperature and pressure measurement functions have pressure sensors installed on the outer surface of the endoscope. The measured pressure is not accurate because the sensor is in contact with the intracavitary tissue at this time and there is pressure generated by passive compression. Therefore, there is a large error and it cannot accurately reflect the pressure in the human body cavity. Summary of the Invention

[0010] Furthermore, it includes a handheld part; a display screen is provided on the handheld part, and a controller is provided inside the handheld part; the controller is connected to the image acquisition device and the sensor group via a data cable, and the data cable is provided inside the second pipeline; the image acquisition device and the sensor group transmit the collected image information, temperature and pressure information to the controller, and after being processed by the controller, the information is transmitted to the display screen for display.

[0011] In the second aspect, the technical solution adopted by the present invention is: a liquid injection control method based on the above-mentioned endoscope, which includes: liquid is transported by a first pipeline, and at the same time, the sensor group located in the second pipeline collects the liquid pressure information output by the front end of the endoscope in real time; the sensor group feeds back the collected liquid pressure information and the temperature information of the front end of the endoscope to the controller in the handheld part in real time; the liquid pressure information is compared with the safety pressure threshold preset in the controller, and the liquid injection control information is output according to the comparison result.

[0012] Furthermore, the comparison includes: if the liquid pressure information is less than the safety pressure threshold, the liquid can be continuously injected; conversely, if the liquid pressure information is greater than or equal to the safety pressure threshold, the injection of the liquid is stopped, thereby effectively ensuring the safe injection amount of the liquid.

The present invention can accurately measure the pressure and amount of the injection.

[0025] In one embodiment of the present invention, an endoscope is provided. In this embodiment, Figure 1 、 Figure 2As shown, the endoscope comprises:

[0026] The first pipeline 1 is used for transporting liquid;

[0027] The second pipeline 2 is symmetrically arranged with the first pipeline 1 and connected to form an endoscope; the front end of the second pipeline 2 is provided with an image acquisition device 3, and a sensor group for collecting temperature and pressure information is provided adjacent to the image acquisition device 3;

[0028] The first pipeline 1 and the second pipeline 2 are sealed and connected; in this embodiment, sealant can be used for the connection.

[0029] In the above embodiment, both the first pipeline 1 and the second pipeline 2 adopt a semi-cylindrical structure, and the two are connected into one body to form a cylindrical structure for easy use and operation.

[0030] In the above embodiment, a mounting groove 4 is provided on the second pipeline 2 adjacent to the image acquisition device 3 and located on the plane side of the second pipeline 2 , and a sensor group is provided in the mounting groove 4 .

[0031] In this embodiment, a sealing structure is provided at the mounting groove 4 to prevent liquid from entering the second pipeline 2 and causing damage to the circuit inside the pipeline.

[0032] In this embodiment, the size of the mounting groove 4 is set to 0.1 mm×2.5 mm. Preferably, the mounting groove 4 is 0.3 mm×0.3 mm.

[0033] In the above embodiment, a through hole 5 is provided on the plane side of the first pipeline 1 at the front end of the first pipeline 1, and the through hole 5 is provided corresponding to the mounting groove 4 on the second pipeline 2; the mounting groove 4 is connected to the first pipeline 1 through the through hole 5, so that the sensor group and the front end of the first pipeline 1 are located in the same pressure environment, and the corresponding temperature and pressure are monitored in real time through the sensor group.

[0034] In the above embodiment, the image acquisition device 3 may be a camera. Specifically, a medical-grade camera is used to efficiently and clearly acquire images of the current environment in real time.

[0035] In the above embodiment, the endoscope of the present invention further includes a handheld portion 6. Handheld portion 6 is provided with a display screen, and a controller is disposed within handheld portion 6. The controller is connected to the camera and sensor assembly via a data cable disposed within second conduit 2. The camera and sensor assembly transmit captured image information, temperature, and pressure information to the controller, which then processes and transmits it to the display screen for display. The decision to continue fluid injection is based on the displayed information.

[0036] In the above embodiment, the sensor group includes at least a temperature sensor and a pressure sensor, and may also include other sensors, which are not listed here exhaustively.

[0037] In the above embodiments, the diameter of the endoscope of the present invention is 7.0Fr to 9.5Fr.

[0038] During use, since the present invention arranges the sensor group for measuring pressure and temperature inside the endoscope, the front end of the first pipeline 1 is the liquid injection end, and the sensor group is adjacent to the injection end, so that the liquid injected at the front end of the endoscope and the front end of the endoscope are in the same pressure environment. At this time, the pressure information collected by the sensor group is the actual pressure of the liquid injected at the front end of the endoscope; the sensor group feeds back the pressure information and the corresponding temperature information collected to the controller to achieve accurate measurement of the perfusion pressure and perfusion amount.

[0040] 1) The first pipeline 1 transports the liquid, while the sensor group located in the second pipeline 2 collects the liquid pressure information output by the front end of the endoscope in real time;

[0041] 2) The sensor group feeds back the collected liquid pressure information and temperature information of the front end of the endoscope to the controller in the handheld part 6 in real time;

[0042] 3) The liquid pressure information is compared with the safety pressure threshold preset in the controller, and the liquid injection control information is output based on the comparison result.

[0043] In the above step 1), since the through hole 5 provided on the first pipeline 1 and the mounting groove 4 provided on the second pipeline 2 are located in the same pressure environment, and the through hole 5 and the mounting groove 4 are both located at the front end of the endoscope, the pressure collected in real time by the sensor group provided in the mounting groove 4 is the same as the pressure at the front end of the endoscope.

[0044] In the above step 3), the specific comparison method is: if the liquid pressure information is less than the safety pressure threshold, the liquid can be continuously injected; conversely, if the liquid pressure information is greater than or equal to the safety pressure threshold, the liquid injection is stopped, thereby effectively ensuring the safe injection amount of the liquid.

[0045] In this embodiment, the safety pressure threshold adopts the existing known safety range of human body pressure, which will not be described in detail here.
