Description

Technical Field

[0001] The present invention belongs to the technical field of endoscopic examination auxiliary instruments, and particularly relates to the field of auxiliary instruments for monitoring gastrointestinal pressure during endoscopic examination. Specifically, it is a system for detecting gastrointestinal signals during endoscopic examination. Background Art

[0002] For digestive tract motility disorder diseases such as Hirschsprung's disease with segmental intestinal spasm or aperistalsis, when performing digestive endoscopy, gas needs to be slowly introduced into the intestine to dilate the intestinal lumen. However, the intestine can only tolerate a limited pressure due to the disease. Once the pressure is too high, there is a risk of barotrauma and gas embolism. Therefore, it is very important to track and measure relevant parameters such as the pressure in the digestive tract in real time to ensure the safety of the intestinal lumen. In addition, when the gastroscope or colonoscope is advancing through a special intestinal segment, it is also necessary to understand the pressure situation in the corresponding intestinal segment to understand the pathological changes of the intestinal segment, so as to provide a clinical diagnosis basis. This also requires real-time monitoring of parameters such as the pressure in the gastrointestinal tract.

[0003] The prior art CN204950936U - a real-time monitoring system for intracavitary pressure of the digestive tract is a technical solution that directly connects a pressure gauge to the biopsy channel through a three-way valve. It is a reading-type pressure monitoring instrument, and specifically, a pointer-type pressure display structure is fixed by tying it to the digestive endoscope. However, the accuracy of detecting by directly connecting the pointer-type pressure gauge to the biopsy channel through a three-way valve is insufficient, and an additional structure is required to fix the pressure gauge. The pressure gauge is arranged outside the endoscope body, and the operator needs to adjust the posture to read the value, which is very inconvenient. Especially for special observation sites, additional staff are required to read the value in real time, which undoubtedly increases the clinical work difficulty.

[0004] Therefore, in view of the problems existing in the prior art, the present invention provides a system for detecting gastrointestinal signals during endoscopic examination. Summary of the Invention

[0005] For the prior art CN204950936U - a real-time monitoring system for intracavitary pressure of the digestive tract, which directly connects a pointer-type pressure gauge to the forceps port of the gastroscope, there are problems of untimely and inaccurate reading. In addition, in order to ensure that the reading is in a frontal state as much as possible, the problem of the effectiveness of reading is solved by stably tying the pressure gauge to the endoscope body. This method requires a long connecting tube, and the long connecting tube is likely to affect the operator during operation. In addition, even if it is tied to the endoscope and depends on manual reading, the reading error is large, and the reading only occurs at some special time points, and the reading is not continuous, which is likely to result in meaningless readings due to inaccurate judgment by the doctor.

[0006] Therefore, in view of the above problems, a device capable of real-time monitoring of the patient's pressure parameters is needed to ensure continuous pressure parameters can be obtained, so as to provide the doctor with a continuous pressure curve to accurately judge the pressure value changes in the gastroscopy or colonoscopy examination area according to the changes in the pressure value. However, the currently commonly used real-time monitoring systems are all relatively large in volume and monitor the pressure value changes in a specific area. For example, in a gastric dynamic pressure monitoring and controlled excitation device with the application number 202310063008.1, it reduces the inaccuracy problem caused by monitoring at one position by setting multiple pressure values through multiple balloons. The above pressure monitoring device is relatively large in volume. During endoscopic examination, the operation end of the endoscope needs to be adjusted and moved at any time. The relatively large-volume pressure monitoring instrument also needs to achieve pipeline connection through a connecting pipe to monitor the pressure. The long pipeline is likely to interfere with the endoscopic operation. Therefore, a miniaturized intermediate structure capable of real-time monitoring of the pressure value is needed, and the pressure value is transmitted through the intermediate structure, displayed on a display structure that is easy to observe, and the change curve of the pressure value is displayed in real time on the display structure through continuous monitoring. If the image captured by the front end of the endoscope can be compared during the process, the pressure values in each area can be detected, and the pressure values of each part during the entire gastroscopy or colonoscopy examination process can be monitored through a detection means, so as to better understand the conditions of each examination part during the entire examination process.

[0007] The present invention specifically relates to a system that can effectively complete signal detection during gastroscopy or colonoscopy, which includes

[0008] A gastroscope or colonoscope system for obtaining image data of the examination or surgical area;

[0009] A real-time signal monitoring system, which includes

[0010] A signal receiving unit, which is connected to the operation channel of the gastroscopy or colonoscopy examination system and is used to receive the pressure value at the in-vivo end of the gastroscope or colonoscope system in real time. A micro pressure sensor and a wireless signal emitting module are arranged therein, and the pressure sensor is electrically connected to the wireless signal emitting module;

[0011] A signal display and processing unit, which is provided with a wireless signal receiving module, receives the real-time pressure value sent back by the wireless signal emitting module of the real-time signal collection device through the wireless signal receiving module, and constructs and displays a pressure curve;

[0012] A connection structure for connecting the real-time signal collection device to the external part of the operation channel of the gastroscope or colonoscope system that communicates with the in-vivo examination or surgical site;

[0013] The signal receiving unit is connected to a gastroscope or colonoscope system through a connection structure, so as to achieve the purpose of the signal receiving unit receiving the pressure value at the in-vivo examination or surgical site; through the settings of the wireless signal transmitting module and the wireless signal receiving module in the signal receiving unit and the signal display and processing unit, the pressure value received by the signal receiving unit in real time can be wirelessly transmitted to the signal display and processing unit, a pressure curve is constructed and displayed, so that when the operator operates, there is no need to check the value of the pressure gauge anymore, but directly observe the pressure value through the display structure.

[0014] Furthermore, in addition to displaying the pressure curve, the signal display and processing unit can also display the real-time pressure value. Through this setting, not only can the pressure value in the current examination and surgical area be observed, but also the change and fluctuation of the pressure value can be understood in combination with the pressure curve, making the diagnostic basis for clinicians more accurate.

[0015] Furthermore, the signal display and processing unit also displays the real-time image data of the patient's examination and surgical site, and compares the image data with the real-time pressure value; through this real-time comparison, the operator can understand the corresponding relationship between the pressure value of the specific endoscopic examination or surgical site and the specific site.

[0016] Furthermore, the corresponding relationship between the real-time image data and the real-time pressure data of the diagnosed patients collected is input into the machine learning system to construct a model relationship between the diseases, real-time pressure data and real-time image data during gastroscopy and colonoscopy examinations and surgeries; and the constructed model relationship is used to assist in the disease diagnosis during gastroscopy and colonoscopy examinations and surgeries. Once this model is constructed, it will greatly reduce the work difficulty of doctors.

[0017] Furthermore, in order to collect more signals related to diseases, a sound receiving module is also integrated in the signal receiving unit. The sound receiving module is used to receive the sound signals in the gastroscope or colonoscope system, and the sound signals also present the amplitude and frequency of the sound in the signal display and processing unit; in this way, the simultaneous acquisition of pressure and sound signals during gastroscopy or colonoscopy examinations and surgeries is completed through the combination of a signal receiving unit and a signal display and processing unit.

[0018] Furthermore, in order to ensure that the connection between the signal receiving unit and the connection structure will not interfere with the operation of the endoscope, a signal receiving head extends out of the signal receiving unit. The signal receiving head is sleeved and combined with the connection structure. The pressure receiving head is a hard head. The pressure receiving head includes an insertion section sleeved and combined with the connection structure, and the length of the insertion section is less than 15 mm; in this way, the signal receiving head and the connection structure can be quickly sleeved, there is no redundant long pipeline, and the operation of the endoscope will not be interfered due to the setting of the signal receiving unit.

[0019] Further, the connection structure is a rigid three-way joint, and its first joint is connected to the external part of the operation channel of the gastroscope or colonoscope system; the connection structure further includes a thin-walled elastic rubber cap provided on the second joint that maintains a sealed state after allowing the operation instrument to enter, and the third joint is connected to the signal receiving unit.

[0020] Further, the signal receiving unit is a small structure with a length not greater than 10 cm, a width not greater than 2 cm, a thickness not greater than 1 cm, and an overall mass not greater than 100 g; such a structure can achieve the effect of maintaining the state after being directly inserted into the connection structure.

[0021] Technical effects

[0022] By connecting the signal receiving unit to the gastroscope or colonoscope system through the connection structure, the purpose of the signal receiving unit receiving the pressure value at the in-vivo examination or surgical site is achieved; through the settings of the wireless signal emitting module and the wireless signal receiving module in the signal receiving unit and the signal display and processing unit, the pressure value received by the signal receiving unit in real time can be wirelessly transmitted to the signal display and processing unit, a pressure curve is constructed and displayed, so that the operator does not need to check the value of the pressure gauge during operation but directly observes the pressure value through the display structure.

[0023] Through the solution of simultaneously displaying the pressure curve and the real-time pressure value on the signal display and processing unit, it is possible to observe both the pressure value in the current examination and surgical area and understand the change and fluctuation of the pressure value in combination with the pressure curve, making the diagnostic basis of clinicians more accurate.

[0024] Through the solution of simultaneously displaying the real-time image data of the patient's examination and surgical site on the signal display and processing unit and forming a comparison between the image data and the real-time pressure value, the operator can understand the corresponding relationship between the pressure value at the specific endoscopic examination or surgical site and the specific site.

[0025] By inputting the corresponding relationship between the real-time image data and the real-time pressure data of the diagnosed patients collected into the machine learning system and constructing a model of diseases, real-time pressure data, and real-time image data during gastroscopy and surgery, the difficulty of doctors' diagnosis of specific diseases during gastroscopy or surgery can be greatly reduced. The model constructed in this way is a dynamic model, which can avoid the probability of diagnostic errors of the constructed static model. Brief description of the drawings

[0036] Embodiment 1

[0037] Reference Figure 1-8 ; A system that can effectively complete signal detection during gastroscopy or colonoscopy, which includes a gastroscope or colonoscope system for obtaining image data of the examination or surgical area;

[0038] A real-time signal monitoring system 2, which includes a signal receiving unit 21, is connected to the operation channel of the gastrointestinal endoscope examination system, and is used to receive the pressure value at the in-vivo end of the gastroscope or colonoscope system in real time. A micro pressure sensor 211 and a wireless signal transmitting module 212 are arranged therein, and the pressure sensor is electrically connected to the wireless signal transmitting module 212; and a signal display and processing unit 22, in which a wireless signal receiving module 223 is arranged, receives the real-time pressure value sent back by the wireless signal transmitting module 212 of the real-time signal collection device through the wireless signal receiving module 223, and constructs and displays a pressure curve.

[0039] A connection structure 3 is used to connect the real-time signal collection device to the external part of the operation channel of the gastroscope or colonoscope system that communicates with the in-vivo examination or surgical site.

[0040] Among them, the wireless signal transmitting module 212 is a Bluetooth module; the wireless signal receiving module 223 is a module for receiving Bluetooth module signals. The signal display and processing unit 22 includes a display structure 221, a microprocessing module 222 and a Bluetooth module. The microprocessing module 222 processes the pressure signal received by the Bluetooth module and displays the pressure signal through the display structure 221.

[0041] Among them, the operation channel can be the forceps channel or the entry channel of other surgical instruments. This channel extends from outside the body to inside the body and connects the in-vivo examination or surgical area with the signal receiving unit 21 outside the body.

[0042] The signal receiving unit 21 is connected to the gastroscope or colonoscope system through the connection structure 3, so as to achieve the purpose of the signal receiving unit 21 receiving the pressure value at the in-vivo examination or surgical site; through the settings of the wireless signal transmitting module 212 and the wireless signal receiving module 223 in the signal receiving unit 21 and the signal display and processing unit 22, the pressure value received by the signal receiving unit 21 in real time can be wirelessly transmitted to the signal display and processing unit 22, a pressure curve is constructed and displayed. In this way, when the operator operates, there is no need to check the value of the pressure gauge anymore, but directly observe the pressure value through the display structure 221.

[0043] In a more preferred embodiment, in addition to displaying the pressure curve, the signal display and processing unit 22 can also display the real-time pressure value. The specific pressure curve and the real-time pressure value are set in different display areas. This setting can ensure that the fluctuation situation is understood through the curve, and the real-time situation is understood through the real-time pressure value, so that the doctor's judgment will be more accurate and the risk of misjudgment due to a single special high value will not occur.

[0044] In a more preferred embodiment, real-time image data of the examination and surgical site of the patient is also displayed on the signal display and processing unit 22, and the image data is compared with the real-time pressure value; through such real-time comparison, the operator can understand the corresponding relationship between the pressure value of the specific endoscopic examination or surgical site and the specific site. Specifically, the signal display and processing unit 22 includes a display structure 221, and the display structure 221 includes a pressure curve display area, a real-time pressure value display area and a real-time image display area; wherein the pressure value display area and the real-time image display area are arranged side by side in the horizontal or vertical direction. Through such an arrangement, doctors can form a comparison well and understand the corresponding relationship between the entered area and the real-time pressure value.

[0045] In a more preferred embodiment, the corresponding relationship between the real-time image data and the real-time pressure data of the diagnosed patients collected is input into the machine learning system to construct a model relationship between the diseases, the real-time pressure data and the real-time image data during gastroscopy and surgery; and the constructed model relationship is used to assist in the disease diagnosis during gastroscopy and surgery. Once this model is constructed, the work difficulty of doctors will be greatly reduced. More specifically, during gastroscopy, the real-time image data and the real-time pressure value data can be intercepted segment by segment according to the moving path of the gastroscope and the corresponding area of the disease, and the real-time image data and the real-time pressure value data are made to correspond to the corresponding gastrointestinal area of the corresponding segment or the corresponding gastrointestinal area of the corresponding disease, so that the corresponding relationship is more accurate.

[0046] In a more preferred embodiment, in order to ensure that the connection between the signal receiving unit 21 and the connection structure 3 will not interfere with the operation of the endoscope, a signal receiving head 2111 protrudes from the signal receiving unit 21, and the signal receiving head 2111 is sleeved with the connection structure 3. The pressure receiving head is a hard head, and the pressure receiving head includes an insertion section sleeved with the connection structure 3, and the length of the insertion section is less than 15 mm; in this way, the signal receiving head 2111 can be quickly sleeved with the connection structure 3, there is no redundant long pipeline, and the operation of the endoscope will not be interfered due to the setting of the signal receiving unit 21.

[0047] In a more preferred embodiment, a sound receiving module is also integrated in the signal receiving unit 21. The sound receiving module is used to receive the sound signal in the gastroscope or colonoscope system, and the amplitude and frequency of the sound are also presented in the signal display and processing unit 22; through the combination of the signal receiving unit 21 and a signal display and processing unit 22, the pressure and sound signals during gastroscopy or surgery are collected simultaneously. More specifically, the sound receiving module is also in contact with the signal receiving head 2111, and the amplitude and frequency corresponding to the sound signal are transmitted to the sound receiving module through the signal receiving head 2111. The sound receiver is a micro sound receiver 213.

[0048] A more preferred embodiment is that the signal receiving unit 21 is a small structure with a length not greater than 10 cm, a width not greater than 2 cm, a thickness not greater than 1 cm, and an overall mass not greater than 100 g. Such a structure can achieve the effect of maintaining its state after being directly inserted into the connection structure 3.

[0049] More specifically, referring to Figure 4-5 , 7 - 8; the signal receiving unit 21 includes a rectangular housing, inside which are provided a micro pressure sensor 211, a Bluetooth module, a microcontroller 216, a micro sound receiver 213, a USB charging interface 217, and a circuit board 218. It also includes a lithium battery 219 that is electrically connected to the USB charging interface 217 for charging. The microcontroller 216 controls the reception of signals and sends the signals to the Bluetooth module, and the signals are transmitted to the Bluetooth module of the signal display and processing unit 22 through the Bluetooth module. Wireless transmission and reception of signals are achieved through the Bluetooth module.

[0050] Among them, the micro pressure sensor 211, the micro sound receiver 213, the microcontroller 216, the Bluetooth module, the switch, and the USB charging interface 217 are all welded on the circuit board 218 and are fixedly installed inside the bottom case 214. The micro pressure sensor 211 is provided with a signal receiving head 2111, and the micro pressure sensor 211 is arranged at the edge position of the rectangular housing, and the signal receiving head 2111 extends out through the short side of the rectangular housing. The opening direction of the USB charging interface 217 is opposite to the direction of the signal receiving head 2111, and the opening of the USB charging interface 217 is arranged on the short side opposite to the signal receiving head 2111. Such a setting can greatly facilitate short-term charging in case the battery runs out during inspection, and it will not provide a large pressure on the insertion part of the signal collection device due to being set in the vertical direction, so that it can maintain the effect of real-time monitoring while charging in the use state. The switch is arranged on the long side of the housing, which can increase the convenience of operation. The lithium battery 219 is fixedly arranged on the top case 215 of the housing. In this way, by arranging other structures at the bottom layer and the lithium battery 219 at the top layer, the entire signal collection device maintains a relatively small state, which is convenient for combination with the connection structure 3. The micro pressure sensor 211 provided therein is a 192D - SS3AI01MGP atmospheric pressure detection low-power chip or an MS4525DO - DS3AS002GPF board-mounted pressure sensor low-power chip module. The bottom case 214 and the top case 215 are connected by screws.

[0051] More specifically, the signal receiving unit 21 includes a pressure sensor, a pressure signal conditioning circuit, a micro sound receiver 213, a sound signal conditioning circuit, and an A / D acquisition circuit. The pressure sensor and the micro sound receiver 213 collect the internal intestinal air pressure signal and the sound signal through connection with the connection structure 3. The above signals are amplified and filtered by the pressure signal conditioning circuit and the sound signal conditioning circuit, and are converted into digital signals by the A / D acquisition circuit for processing by the microprocessing module 222, and the processed signals are sent out through the wireless signal sending module.

[0052] Reference Figure 4-6; The implementation of the connection structure 3 is as follows: The connection structure 3 is a rigid three-way joint, and the connection structure 3 includes a first joint 31, a second joint 32, and a third joint 33; wherein, the first joint 31 is connected to the external part of the operation channel of the gastroscope or colonoscope system; the connection structure 3 further includes a thin-walled elastic rubber cap 323 provided on the second joint 32 that maintains a sealed state after the operation instrument enters, and the third joint 33 is connected to the signal receiving unit 21, and the third joint 33 is connected to the signal receiving head 2111 extending from the signal receiving unit 21. The inner diameter of the first joint 31 is the same as the outer diameter of the external part of the operation channel. An annular groove is provided on the inner side wall of the first joint 31, and an annular sealing ring 311 is provided in the annular groove. Through this setting, the sealing performance of the overall environment after connection can be ensured, and the accuracy of the monitored pressure can be ensured. A first protruding ring 321 and a second protruding ring 322 are provided on the second joint 32, and the outer diameter of the first protruding ring 321 is smaller than that of the second protruding ring 322; wherein the first protruding ring 321 is provided at the opening position of the second connector, the second protruding ring 322 is arranged away from the first protruding ring 321, and the first end of the thin-walled elastic rubber cap 323 is arranged between the first protruding ring 321 and the second protruding ring 322. Through the setting of the first protruding ring 321 and the second protruding ring 322, the thin-walled elastic rubber cap 323 can be fixed between the two rings, and will not move down excessively or easily come out of the second joint 32. The second end of the thin-walled elastic rubber cap 323 is provided with an instrument passing wall with a cross-shaped opening; in this way, it can be ensured that the cross-shaped opening maintains close contact with the operation instrument when the instrument passes through, and the sealed state is maintained; the inner diameter of the second joint 32 is the same as the outer diameter of the operation instrument; a tapered head 331 is provided at the end of the third joint, and a silicone tube is connected to the tapered head 331. Although the silicone tube can be deformed, it has a certain hardness, and the length of the silicone tube is less than 2 cm. A further method is that when the third connector and the signal receiving head 2111 are both inserted into the silicone tube to achieve connection, the ends of the third connector and the signal receiving head 2111 are in contact. This setting method can greatly facilitate the effective combination of the third connector and the signal receiving head 2111, and the combination can be achieved through a simple plugging method. This combination method can also ensure the sealed state at the connection after combination. In addition, because the ends of the connectors are in contact after combination, there is no risk of deformation or blockage of the entire connected passage due to the hard connection of the connectors.Further, the diameter of the protruding ring two 322 is the same as that of the first joint 31 part, and a connecting section 35 is provided between the first joint 31 and the protruding ring two 322. The outer diameter of the connecting section 35 is smaller than the outer diameter of the protruding ring two 322. This setting can facilitate pinching at the position of the connecting section 35 to set the connecting structure 3 to the external part of the operation channel or to remove it from the external part of the operation channel with ease. When setting, the second joint 32 blocks the pinching fingers, facilitating the application of force in the direction towards the external part of the operation channel to set the connecting structure 3 in the direction of the external part; when removing, the protruding ring two 322 blocks the pinching fingers, facilitating the application of force in the direction away from the external part of the operation channel to remove the connecting structure 3.
