Description

Technical Field

[0001] The present application relates to an endoscope system for inspecting and treating organs, and in particular to an endoscope system with analysis and treatment functions for inspecting and treating organs and other body structures. Background Art

[0002] Urinary tract stones are common and frequently occurring diseases. They have been recorded as early as in ancient times. Chinese medicine calls them "stone stranguria" or "sand stranguria". This disease is closely related to the environment, systemic diseases and other diseases of the urinary system, and the mechanism of stone formation has not been fully elucidated. With the improvement of people's living standards and changes in dietary structure, the incidence of upper urinary tract stones has increased significantly, while that of lower urinary tract stones has decreased. Bladder and urethral stones belong to lower urinary tract stones, most of which are caused by secondary factors. Primary bladder stones are rare and are generally more common in children. This is related to malnutrition and low-protein diet after weaning. Secondary bladder stones are more common in elderly men. Common causes include upper urinary tract stones discharged into the bladder, lower urinary tract obstruction causing urine retention, infection, foreign bodies, etc. Urethral stones are rare. Most of them are caused by stones from the kidneys and bladder passing through the urethra or embedded in the urethra. There are also a few primary urethral stones that occur in urethral stenosis, foreign bodies or diverticula that open into the urethra.

[0003] The use of endoscopes in the medical field usually involves inserting a slender insertion part (tube) into the patient's body, which can directly observe the patient's internal organs and expand the surgical field of view. The outstanding features of using endoscopes are that the surgical incisions are generally small, and the incision scars are not obvious, the postoperative reactions are mild, the bleeding, bruising and swelling time can be greatly reduced, and the postoperative recovery is much faster than traditional surgery. Utility Model Content

[0004] Diseases such as kidney stones usually require imaging examination before they can be treated with laser lithotripsy. To address the above problems, the present application proposes an endoscope system that can simultaneously analyze and treat stones.

[0005] The endoscope system belongs to a medical device.

[0006] An endoscope system having both stone diagnosis and treatment functions, characterized in that it comprises:

[0007] Endoscope;

[0008] An illuminator capable of emitting light of different wavelengths, wherein the optical fiber connected to the illuminator can move freely in the working channel of the endoscope;

[0009] A host computer connected to the endoscope and the light emitter and capable of analyzing and processing images collected when the light emitter emits infrared light to the lesion; and

[0010] A display device connected to a host computer that can display images captured by an endoscope.

[0011] Furthermore, the endoscope comprises:

[0012] The outermost casing,

[0013] An eyepiece with image acquisition function is arranged at one end of the sleeve.

[0014] an illumination optical fiber extending into the sleeve and located on both sides of the sleeve edge for emitting illumination light; and

[0015] The endoscope working channel is located in the center of the cannula and runs through the entire cannula.

[0016] Furthermore, the eyepiece is selected from an eyepiece with a CCD chip or an eyepiece with a CMOS chip.

[0017] Furthermore, the optical signal collected by the eyepiece is converted into an electrical signal and then transmitted to the host.

[0018] Furthermore, the core diameter of the optical fiber is 200-1000 μm, preferably 200-550 μm.

[0019] Furthermore, the illumination light is LED light or tungsten halogen light.

[0020] Furthermore, the working channel is a hollow tube for passing surgical operation tools and optical fibers connected to the light emitter.

[0021] Further, the sleeve is flexible.

[0022] Furthermore, the light emitter can emit infrared light or laser light and transmit it through the catheter fiber connected thereto.

[0023] Furthermore, the pulse duration of the light emitter is 250-1500 μs.

[0024] Furthermore, the frequency of the laser emitted by the light emitter is 5-200 Hz.

[0025] Furthermore, the laser energy emitted by the light emitter is 0.1-6J, preferably 0.1-2.4J.

[0026] Furthermore, the host calculates the energy required to clear the lesion based on the analysis of the image collected by the eyepiece when the light emitter emits infrared light to the lesion, and further controls the light emitter to emit laser and transmit it to the lesion based on the calculated energy.

[0027] Furthermore, the host calculates multiple solutions based on the energy required to remove the lesion and presents the solutions on the human-machine interface of the light emitter for the user to select the optimal energy to control the light emitter to emit laser and transmit it to the lesion.

[0028] The beneficial effect of the present application is: an endoscope system with analysis and treatment functions is obtained by combining an endoscope with a host, a display device and a light emitter. In the system, the endoscope serves as both a lens for capturing images inside the patient's body and a carrier for enabling analysis and treatment light to enter the patient's body and directly hit the lesion, so that the user can analyze and treat the patient's condition more flexibly and efficiently; at the same time, the light emitter has a human-computer interaction panel, and according to the energy required to remove the lesion calculated by the host, several treatment plans are displayed on the interactive interface. The difference in treatment plans is reflected in the size of the laser output energy and the length of the laser output time. After the user diagnoses and selects a more scientific laser output plan, the temperature of the affected area will not be too high under the premise of effectively removing the lesion, thereby avoiding discomfort or pain to the patient's body.

[0034] The following is a description of the exemplary embodiments of the present application, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0035] See also Figure 1The present application proposes an endoscope system, which has the functions of analyzing the composition of stones and treating lesions. The system comprises: an endoscope 1, which can capture and collect images of lesions in the patient's body through the endoscope 1; a light emitter 2, which can irradiate diagnostic light such as infrared light or therapeutic light such as laser to the patient's lesion; a host 3, which can analyze the spectrum collected when the lesion is irradiated and calculate the energy required to clear the lesion; a display device 4, which images the images collected by the endoscope 1.

[0036] The endoscope system proposed in the present application can observe lesions in the kidneys, ureters, bladder, etc. when diagnosing a disease, just like a traditional endoscope; in the present application, the lesions are various stones, such as kidney stones, bladder stones, prostate stones, urethral stones, and ureteral stones.

[0037] According to the requirements of the use scenario and the characteristics of the endoscope, the endoscope 1 is selected from one of an optical fiber (flexible tube) endoscope, a hard tube endoscope or an electronic endoscope; in a specific solution of the present application, the examinee needs to take the lithotomy position after emptying the bladder, and the endoscope 1 used at this time uses a metal hard tube endoscope for treatment. The imaging when using a hard tube endoscope is clearer and the operation is more convenient; in a specific solution of the present application, the examinee suffers from upper urinary tract stones, and the diameter of the front end of the ureter is relatively narrow, generally 2-3mm, which is very suitable for diagnosis and treatment with an optical fiber (flexible tube) endoscope that allows optical fiber to pass through even when bent, so the endoscope 1 uses an optical fiber (flexible tube) endoscope;

[0038] In a specific scheme of the present application, the endoscope 1 is an electronic endoscope, which is mainly composed of an eyepiece 10, an illumination fiber 11, a working channel 12 and a sleeve 13. The outermost part of the endoscope is the sleeve 13, which is flexible and bends when entering the user's bladder or urethra. The lens of the eyepiece 10 is a CCD or CMOS lens, which is located at the center of the sleeve 13. The eyepiece 10 converts an optical signal into an electrical signal, which is transmitted through the mirror body line and finally presents an image on the display device 4. The illumination fiber 11 uses a light source such as an LED lamp or a tungsten lamp to emit a light beam in the same direction as the eyepiece 10, providing lighting when the endoscope 1 is working. The working channel 12 is a circular through hole that runs through the entire sleeve 13. The working channel 12 can pass through operating tools such as an endoscope and a sampling forceps. In the present application, the working channel 12 can also pass through an optical fiber connected to the light emitter 2.

[0039] An endoscope system composed of an endoscope 1 also includes a light source 2, a host 3 and a display device 4.

[0040] The light emitter 2 is a multifunctional light wave emitting device. The light emitter 2 can switch infrared light, ultraviolet light or laser light at will according to different diagnosis and treatment needs. The light emitter 2 can only emit one type of light wave at the same time. The light emitter 2 has the same principle as the infrared spectrum acquisition device of the Fourier transform infrared spectrometer. The infrared light emitted by the light source is converted into interference light by the interferometer, and then emitted to the stone from the optical fiber connected to the light emitter 2 through the working channel 12 of the endoscope 1. After passing through the stone, an interference pattern containing stone information is obtained, which is collected by the host 3 and subjected to fast Fourier transform to obtain an infrared spectrum in which the absorption intensity or transmittance changes with the frequency or wave number.

[0041] The laser emitted by the light emitter 2 can be a holmium laser or a thulium laser. The holmium laser is a holmium laser that adopts a flash lamp pumping structure, emits an infrared wavelength of 2100nm, and transmits energy through a 200-1000μm low-hydroxyl silica core optical fiber. For example, it can be 200μm, 250μm, 300μm, 350μm, 400μm, 450μm, 500μm, 550μm, 600μm, 650μm, 700μm, 750μm, 800μm, 850μm, 900μm, 950μm, or 1000μm.

[0042] The laser operates in pulse mode, and the pulse energy is set to 0.1-6.0J, for example, 0.1, 0.2J, 0.3J, 0.4J, 0.5J, 0.6J, 0.7J, 0.8J, 0.9J, 1.0J, 1.1J, 1.2J, 1.3J, 1.4J, 1.5J, 1.6J, 1.7J, 1.8J, 1.9J, 2.0J, 2.1J, 2.2J, 2.3J, 2.4J, 2.5J, 2.6J, 2.7J , 2.8J, 2.9J, 3.0J, 3.1J, 3.2J, 3.3J, 3.4J, 3.5J, 3.6J, 3.7J, 3.8J, 3.9J, 4.0J, 4.1J, 4.2J, 4.3J, 4. 4J, 4.5J, 4.6J, 4.7J, 4.8J, 4.9J, 5.0J, 5.1J, 5.2J, 5.3J, 5.4J, 5.5J, 5.6J, 5.7J, 5.8J, 5.9J, 6.0J.

[0043] The pulse duration is 250-1500μs, for example, it can be 250μs, 300μs, 350μs, 400μs, 450μs, 500μs, 550μs, 600μs, 650μs, 700μs, 750μs, 800μs, 850μs, 900μs, 950μs, 1000μs, 1050μs, 1100μs, 1150μs, 1200μs, 1250μs, 1300μs, 1350μs, 1400μs, 1450μs, 1500μs.

[0044] The pulse rate is 5-200Hz, for example, it can be 5Hz, 10Hz, 15Hz, 20Hz, 25Hz, 30Hz, 35Hz, 40Hz, 45Hz, 50Hz, 55Hz, 60Hz, 65Hz, 70Hz, 75Hz, 80Hz, 85Hz, 90Hz, 95Hz, 100Hz, 105Hz, 110Hz, 115Hz, 120Hz, 125Hz, 130Hz, 135Hz, 140Hz, 145Hz, 150Hz, 155Hz, 160Hz, 165Hz, 170Hz, 175Hz, 180Hz, 185Hz, 190Hz, 195Hz, and 200Hz.

[0045] The average power is up to 120W. According to the relevant parameters of the set light emitter, the wavelength of thulium laser is 1940nm. Compared with the fragmentation mode of high pulse energy and low pulse frequency of holmium laser, the powderization mode of low pulse energy and high pulse frequency of thulium laser has smaller stone displacement and can ablate stones faster.

[0046] The host 3 is an intelligent device with analysis and calculation capabilities independent of the light emitter 2. It can be any intelligent device such as a desktop computer, an all-in-one computer, a laptop computer, a PDA, a tablet computer, etc. that can meet the computing power required for the diagnosis and treatment process of the endoscope system. The host 3 can analyze the interference diagram containing stone information obtained by irradiating the stone in the diagnosis stage. The host 3 performs fast calculation of digital / analog conversion and Fourier transform, and can convert the time domain interference diagram into a frequency domain spectrum with wave number as the horizontal coordinate, that is, a spectrum diagram. The analysis of the infrared spectrometer is the process of identifying the composition of the stone based on the peak position, peak intensity and peak shape in the spectrum diagram. The host 3 will automatically analyze and present the report and analysis results through the automatic analysis system. According to the obtained stone analysis results, namely stone density, stone volume, etc., the required laser energy and the laser action time under the laser energy are calculated as a treatment plan for the user to choose.

[0047] In one solution of the present application, the display device 4 can be any device that can output images or tactile information, specifically a two-dimensional image display such as a computer display, a TV screen, a mobile phone screen, a head-mounted display, a physiological monitor, etc.

[0048] Example

[0049] like Figure 2 As shown in the figure, in one scheme of the present application, the endoscope 1 is an electronic endoscope, the host 3 is a desktop computer, the display device 4 is a computer display screen, the light emitter 2 is internally connected to an optical fiber, and the optical fiber runs through the working channel 12 of the endoscope 1. The eyepiece 10 of the endoscope 1 converts an optical signal into an electrical signal, and the electrical signal is transmitted to the host 3 through the mirror body line. The host 3 is electrically connected to the display device 4, and the host 3 can output the electrical signal to the display device 4 to complete the imaging of the patient's body image; the host 3 is also electrically connected to the light emitter 2, and can output the analysis and diagnosis content of the host 2 back to the light emitter to be presented on the human-computer interaction interface of the light emitter 2.

[0050] Example 1

[0051] In this embodiment, an endoscope system diagnostic process according to one implementation scheme will be demonstrated.

[0052] In the diagnosis stage, the endoscope 1 enters the patient's bladder or urethra under the operation of the user. The operator captures the image of the lesion in the patient's body through the eyepiece 10 of the endoscope 1. The electronic soft endoscope collects the image through the CMOS chip, and the specific image is observed from the display device 4 connected to the endoscope 1. At this time, the light emitter 2 selects to emit infrared light to irradiate the stones found in the patient's body. When the stone absorbs infrared radiation of a certain frequency, the vibration energy level of the molecule transitions, and the light of the corresponding frequency in the transmitted light beam is weakened, resulting in the intensity difference between the reference light path and the sample light path, thereby obtaining the infrared spectrum of the measured stone. The host 3 analyzes the results through the collected spectrum to determine the stone composition, matches the hardness data of the corresponding stone composition, matches the laser energy parameters corresponding to the stone of the hardness and composition, and displays each parameter scheme on the human-machine panel of the light emitter 2 for the user to determine the selected scheme.

[0053] Example 2

[0054] In this example, a treatment process of an endoscope system according to one embodiment will be demonstrated.

[0055] The material of the optical fiber is quartz glass, and the core diameter is 200μm. When in the treatment stage, the treatment plan obtained in the diagnosis stage is displayed on the human-machine interaction panel on the light emitter 2. After operating on the human-machine interaction panel, the light emitter 2 emits a short-pulse laser with a pulse energy of 1.2J to irradiate the lesion, and the pulse frequency is 10Hz. While completing the stone treatment, it avoids causing discomfort or pain to the patient's body. Finally, the stone is broken into pieces, and the subject is in good physical condition. See Table 1 for details.
