Description

TECHNICAL FIELD

[0001] The utility model relates to medical examination instrument field, especially an electronic endoscope. BACKGROUND

[0002] Endoscopes play a crucial role in modern medical diagnosis and treatment. They not only provide real-time images of the internal body cavity but also support various minimally invasive surgical operations through instrument channels. To further enhance the safety and effectiveness of endoscopic surgery, accurate monitoring of pressure and temperature on the patient's site during the operation becomes particularly important.

[0003] Prior art such as CN115868903A and CN111700581A proposes a design scheme of integrating multiple functional modules at the front end of the endoscope, including image systems, instrument channels, light sources, pressure measuring elements, and temperature measuring elements. The temperature and pressure of different parts of the human body may vary due to factors such as blood circulation, tissue type, or pathological state. However, these designs separate the pressure measuring elements and temperature measuring elements far apart, usually separated by image systems and instrument channels, resulting in differences in measurement point locations. This leads to the data obtained by the pressure measuring elements and temperature measuring elements not reflecting the true conditions of the same local environment, resulting in poor accuracy of detection data and misleading doctors' decisions, thereby affecting the effectiveness of the operation. SUMMARY

[0004] The purpose of the utility model is to provide an electronic endoscope that solves the problem of poor accuracy of detection data in the prior art, optimizes the layout of pressure measuring elements and temperature measuring elements, and improves data accuracy.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an electronic endoscope, comprising a main body, one end of the main body is connected with a scope tube for insertion into a subject, the other end of the main body is connected with an operation part, the front end face of the scope tube is provided with an instrument channel, an image system, a light source, a pressure measuring element, and a temperature measuring element, the image system and the instrument channel are arranged side by side to divide the front end face of the scope tube into two installation areas on both sides of the image system and the instrument channel, and the pressure measuring element and the temperature measuring element are located in the same installation area and are arranged close to each other.

[0006] The utility model discloses the following advantages: the pressure measuring element and the temperature measuring element are located in the same installation area and close to each other, so that the positions detected by them tend to be the real pressure and temperature conditions of the same local environment or even the same point, which can more accurately reflect the real pressure and temperature conditions at the local environment or the point position, reduce the error caused by measurement at different positions, and provide more accurate data, thereby improving the accuracy of diagnosis.

[0007] Further, the light source is located in a different installation area from the pressure measuring element and the temperature measuring element.

[0008] With the foregoing technical solution, the light source may generate heat when working, and if the light source is close to the temperature measuring element, the temperature measurement value may be inaccurate. By placing the light source in a different installation area from the temperature measuring element, the heat generated by the light source can be avoided as much as possible to interfere with temperature measurement, thereby ensuring the accuracy of temperature data. Different installation areas can make the layout of each functional module on the front end face of the scope tube more reasonable and compact.

[0010] With the foregoing technical solution, the heat generated by the light source when working may be transmitted to the surrounding area through the gap. Arranging the temperature measuring element away from the gap can effectively reduce the interference caused by heat conduction, thereby ensuring as much as possible that the temperature measured is the real temperature of the target area.

[0011] Further, the temperature measuring element is arranged protruding from the front end face of the scope tube.

[0012] With the foregoing technical solution, the protruding arrangement can make the temperature measuring element closer to the target tissue, reducing the influence of the air layer or liquid layer between the front end face of the scope tube and the tissue on temperature measurement, which helps to obtain more real local temperature data.

[0013] Further, the scope tube includes a tip having the front end face and a tube body for connecting with the main body, and the tip and the tube body are detachably connected.

[0014] With the foregoing technical solution, the detachable connection of the tip and the tube body facilitates sterilization and is conducive to repeated use.

[0015] Further, the end head is provided with a plug hole for inserting the pipe body, and the pipe body and the plug hole are plugged; or the end head is provided with a clamping groove or a clamping protrusion, and the side wall of the pipe body is correspondingly provided with a clamping protrusion or a clamping groove, and the clamping protrusion and the clamping groove are matched to realize the connection of the end head and the pipe body.

[0016] Through the above technical solution, the connection of the end head and the pipe body can be completed through simple insertion operation, so that the installation and disassembly process is fast and simple; or the design of the clamping groove and the clamping protrusion can provide more firm mechanical locking while making installation and disassembly more convenient, and can prevent the end head from accidentally separating from the pipe body as much as possible.

[0017] Further, the pipe body includes a rigid pipe arranged in a straight line or a flexible hose.

[0018] Through the above technical solution, since the end head and the pipe body are detachable, the functional configuration of the endoscope can be quickly adjusted according to actual needs, such as mounting the end head on a rigid pipe or a flexible hose, which means that the same system can adapt to various medical examination and treatment needs.

[0019] Further, the mirror pipe is provided with a pressure detection channel and a temperature detection channel, the temperature measuring element includes a temperature transmission component arranged in the temperature detection channel and a temperature sensor arranged in the main body, the temperature transmission component is used to transmit the temperature of the object to the temperature sensor, and the pressure measuring element includes a pressure transmission component arranged in the pressure detection channel and a pressure sensor arranged in the main body, the pressure transmission component is used to transmit the pressure of the object to the pressure sensor.

[0020] Through the above technical solution, the temperature and pressure information can be transmitted by using special transmission components, which can reduce signal attenuation and external electromagnetic interference, and can ensure the stability and accuracy of data transmission as much as possible.

[0021] Further, the pressure detection channel and the temperature detection channel are arranged in a spaced manner.

[0022] Through the above technical solution, the two detection channels are arranged in a spaced manner, which can more effectively avoid direct interference between each other, and can ensure that the respective sensors can accurately obtain the required data as much as possible, such as the influence of the trace amount of heat generated by the pressure sensor on the temperature measurement on the other side.

[0036] It should be understood that in the present application, "multiple" means two or more. "And / or" is only a description of the relationship between the associated objects, which means that there can be three relationships, for example, X and / or Y can represent the three cases of X alone, X and Y together, and Y alone. The character " / " generally represents that the associated objects before and after are in an "or" relationship.

[0037] The technical solutions of the present application will be described in detail below with specific examples. The following specific examples can be combined or replaced according to actual conditions, and the same or similar concepts or processes may not be described in some embodiments.

[0038] As shown in Figures 1 to 5 The present application provides an electronic endoscope, which comprises a main body 10, a mirror tube 20 connected to one end of the main body 10 for insertion into a subject, an operating part 30 connected to the other end of the main body 10, an instrument channel 22 provided on the front end face 21 of the mirror tube 20, an image system 23, a light source 24, a pressure measuring element 26 and a temperature measuring element 25, the image system 23 and the instrument channel 22 are arranged side by side to divide the front end face 21 of the mirror tube 20 into two installation areas on both sides of the image system 23 and the instrument channel 22, and the pressure measuring element 26 and the temperature measuring element 25 are located in the same installation area and are arranged close to each other.

[0039] Since the pressure measuring element 26 and the temperature measuring element 25 are located in the same mounting area and close to each other, the positions detected by them tend to be the real pressure and temperature conditions of the same local environment or even the same point, which can more accurately reflect the real pressure and temperature conditions of the local environment or the point position, reduce the errors caused by different positions, help to provide more accurate data, and improve the accuracy of diagnosis. The pressure measuring element 26 and the temperature measuring element 25 are integrated in one area, which can also make the design of the endoscope more compact and reasonable, and facilitate the power supply of the pressure measuring element 26 and the temperature measuring element 25 and the wiring of the signal transmission line.

[0040] It should be noted that the image system 23 includes a camera for shooting images of the surgical area in the subject, and the scope tube 20 is provided with an illumination optical fiber, and the light incident end of the illumination optical fiber is used for directly or indirectly connecting the light source 24, which can complete the illumination of the surgical area. The instrument channel 22 can be connected with an operating inner knife, an operating outer knife and a suction and irrigation platform for surgery.

[0041] Since the light source 24 may generate heat when working, if the light source 24 is close to the temperature measuring element 25, it may cause inaccurate temperature measurement. Therefore, the light source 24 is located in a different mounting area from the pressure measuring element 26 and the temperature measuring element 25, which can avoid the interference of heat generated by the light source 24 on temperature measurement as much as possible, thereby ensuring the accuracy of temperature data. Different mounting areas can make the layout of each functional module on the front end face 21 of the scope tube 20 more reasonable and compact.

[0042] In addition, there is a gap 27 between the image system 23 and the instrument channel 22, and the heat generated by the light source 24 when working may be transmitted to the surrounding area through the gap 27. Therefore, the temperature measuring element 25 is arranged away from the gap 27, which can effectively reduce the interference caused by heat conduction, thereby ensuring that it measures the real temperature of the target area as much as possible. In the embodiment, the temperature measuring element 25 is located on one side of the image system 23.

[0043] In order to further improve the detection accuracy, the temperature measuring element 25 is arranged to protrude from the front end face 21 of the scope tube 20, which can make the temperature measuring element 25 closer to the target tissue, reduce the influence of the air layer or liquid layer between the front end face 21 of the scope tube 20 and the tissue on temperature measurement, and help to obtain more real local temperature data.

[0044] Specifically, the mirror tube 20 is provided with a pressure detection channel 203 and a temperature detection channel, the temperature measuring element 25 includes a temperature transmission component arranged in the temperature detection channel and a temperature sensor arranged on the main body 10, the temperature transmission component is used to transmit the temperature of the object to the temperature sensor, and the pressure measuring element 26 includes a pressure transmission component arranged in the pressure detection channel 203 and a pressure sensor 261 arranged on the main body 10, the pressure transmission component is used to transmit the pressure of the object to the pressure sensor 261. Using a special transmission component to transmit temperature and pressure information can reduce signal attenuation and external electromagnetic interference, and can ensure the stability and accuracy of data transmission as much as possible.

[0045] It should be noted that the temperature transmission component includes a temperature sensing probe 252 protruding from the front end face 21 of the mirror tube 20 and a data transmission wire connected with the temperature sensor, and the pressure transmission component is a through pipeline. In this embodiment, the temperature sensor is only a temperature sensor board 251, which converts the temperature detected by the temperature sensing probe 252 into a digital signal output.

[0046] Further, the pressure detection channel 203 and the temperature detection channel are arranged at intervals. Arranging the two detection channels at intervals can more effectively avoid direct interference between them, and can ensure that the respective sensors can accurately acquire the required data as much as possible, such as the influence of the trace amount of heat generated by the pressure sensor 261 during operation on the temperature measurement on the other side.

[0047] In order to facilitate the cleaning, disinfection and sterilization requirements, the mirror tube 20 includes a head 201 having a front end face 21 and a tube body 202 for connecting with the main body 10, and the head 201 and the tube body 202 are detachably connected, which is convenient for independent disinfection and repeated use.

[0048] Specifically, the head 201 is provided with a plug-in hole for inserting the tube body 202, and the tube body 202 and the plug-in hole are plugged in, so that the installation and disassembly process is quick and simple.

[0049] In addition, in order to increase the application range, as shown in Figures 1 to 4 In one embodiment, the tube body 202 includes a flexible hose. As shown in Figure 5 In another embodiment, the tube body 202 includes a rigid tube, and the two embodiments can be applied to the same head 201. Since the head 201 and the tube body 202 are detachable, the functional configuration of the endoscope can be quickly adjusted according to actual needs.

[0050] Finally, the operation part 30 is further provided with an optical connector 31 connected with the image system 23, and a data connector 32 connected with the temperature sensor and the pressure sensor 261 respectively, the image system 23 outputs video images through the optical connector 31, and the data connector 32 outputs pressure parameters and temperature parameters, the optical connector 31 and the data connector 32 are arranged separately, which can effectively avoid mutual interference between different types of signals, ensure image definition and data accuracy, and also facilitate users to distinguish between the two. The optical connector 31 and the data connector 32 can be externally connected with a display controller, so that the image and the data can be visualized. The data connector 32 is a PCI data socket.

[0051] Working principle: the mirror tube 20 is inserted into the lesion organ, the image system 23 outputs video images to the display controller through the optical connector 31, the pressure transmission component transmits the intracavity pressure to the pressure sensor 261, the pressure sensor 261 converts the pressure data into a digital signal, and the data connector 32 outputs to the display controller; during the operation process, the temperature sensing probe 252 transmits the intracavity temperature to the temperature sensor and converts the temperature into a digital signal output to the display controller. When the pressure and the temperature exceed the set parameter range, the suction platform will respond in time and make corresponding compensation, so as to keep the inner cavity in a more reasonable and safe range environment and ensure the safety of the operation process as much as possible.
