[0002] A gastroscope is an endoscopic instrument used to help doctors examine the inside of a patient's stomach. Compared to traditional gastroscopes (rigid scopes), gastroscopes have softer and more flexible probes, allowing doctors to pass through the esophagus into the stomach more easily and better adapt to the bends and tortuosity of the stomach. Gastroscopes are commonly used to examine stomach lesions, ulcers, inflammation, bleeding, etc., as well as to perform biopsies or therapeutic procedures. During a gastroscopy, patients usually need to take specific medications to prepare their intestines, and may need local anesthesia or sedatives to reduce discomfort.

[0003] Traditional gastroscopes usually require a large workstation, that is, they need to be equipped with a light source system, a camera system, and a display on the workstation to work. To prepare a gastroscope, a professional nurse is required to connect the light source system, the camera system, dialogue, focus, adjust the display, etc., which is time-consuming, and it will take even longer if a non-specialist nurse is involved. There is currently a visual soft mirror that sets a small display device on the main body of the soft mirror, which greatly improves the integration of the soft mirror. In actual operation, the main body of the visual soft mirror needs to be moved frequently to assist the insertion part to move in the patient's body. However, when the main body of the soft mirror with an integrated display device is moved, the display device will shake, affecting the medical staff's viewing of the image on the display device.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0039] On the one hand, the utility model provides Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a visual gastroscope is used to help doctors examine the internal conditions of the patient's stomach, so that doctors can more easily pass through the esophagus into the stomach, and can better adapt to the bending and tortuosity of the stomach. Gastroscopes are usually used to examine gastric lesions, ulcers, inflammation, bleeding, etc., as well as to perform biopsy or treatment operations. The main structure includes: a soft mirror body 1, a display device 2, a pan-tilt assembly 4 and a liquid delivery assembly 3. The soft mirror body 1 includes a handle portion 11 and an insertion portion 12. The handle portion 11 is provided with an operating device 13, and the operating device 13 is used to control the bending of the end of the insertion portion 12. The end of the insertion portion 12 is provided with a camera 121. The pan-tilt assembly 4 is arranged on the handle portion 11; the display device 2 is arranged on the pan-tilt assembly 4, and the display device 2 is used to display the image of the camera 121. The liquid delivery assembly 3 is connected to the handle portion 11, and the liquid delivery assembly 3 is connected to the insertion portion 12 pipeline, and the liquid delivery assembly 3 is used to deliver liquid to the insertion portion 12; wherein the pan-tilt assembly 4 is used to keep the display device 2 stable. wherein the display device 2 is preferably a touch-type liquid crystal display. The operating device 13 may include buttons, joysticks, etc. The display device 2 may be integrally formed with the handle portion 11, and the two may be movably connected (so that medical staff can adjust the pitch angle or left and right angle of the display device 2 as needed).

[0040] It is understandable that the specific function of the operating device 13 in this embodiment to control the bending of the end of the insertion portion 12 can be obtained by those skilled in the art based on the prior art, and the structure and working principle of the operating device 13 will not be described in detail here.

[0041] It should be noted that the existing visual soft mirror has a small display device 2 disposed on the soft mirror body 1, which greatly improves the integration of the soft mirror. In actual operation, the visual soft mirror body 1 needs to be frequently moved to assist the insertion portion 12 to move in the patient's body. However, when the soft mirror body with the integrated display device 2 is moved, the display device 2 will be shaken, affecting the medical staff's viewing of the image of the display device 2.

[0042] This solution integrates the soft mirror body 1, camera 121, lighting device 124 and display device 2, and preferably uses a touch-type liquid crystal display device 2 instead of a traditional desktop display, thereby greatly reducing the overall size of the device, improving the portability of the gastroscope, and making it more convenient to use. Therefore, the scope of gastroscope usage scenarios is expanded. The display device 2 is mounted on the pan-tilt assembly 4 of the handle portion 11, and the display device 2 is lifted by the pan-tilt assembly 4 to keep the display device 2 stable. When the medical staff operates the soft mirror body 1 to adjust the position of the insertion portion 12, several motors on the pan-tilt assembly 4 perform angle compensation according to the movement of the soft mirror body 1, effectively keeping the display device 2 stable and avoiding affecting the medical staff's viewing of the image of the display device 2. During specific use, it is only necessary to connect the liquid delivery assembly 3 and the insertion portion 12 to the handle portion 11 respectively, adjust the initial angle of the display device 2, and then gradually insert the insertion portion 12 into the patient's stomach and intestines for gastroscopy. During this period, the medical staff needs to constantly operate the control buttons on the handle portion 11 and move the handle portion 11 so that the insertion portion 12 can be smoothly moved in the patient's stomach. Among them, the liquid delivery component 3 can deliver liquid to the insertion portion 12 for cleaning the camera 121 and operating the forceps. Therefore, the liquid delivery component 3 usually includes a liquid pumping component (responsible for pumping in cleaning liquid) and a liquid extraction component (responsible for extracting liquid or contaminants in the stomach).

[0043] Further, such as Figure 1 , Figure 2 As shown, the pan / tilt assembly 4 includes: a first motor 41, a first connecting arm 42, a second motor 43, a second connecting arm 44, a third motor 45 and a connecting seat 46, the first motor 41 is connected to one end of the first connecting arm 42 and is used to drive the first connecting arm 42 to rotate, the other end of the first connecting arm 42 is connected to the second motor 43, the second motor 43 is connected to one end of the second connecting arm 44 and is used to drive the second connecting arm 44 to rotate, the other end of the second connecting arm 44 is connected to the third motor 45, the third motor 45 is connected to the connecting seat 46 and is used to drive the connecting seat 46 to rotate, and the connecting seat 46 is connected to the display device 2;

[0044] The handle portion 11 is connected to the first motor 41 .

[0045] Furthermore, the rotation axis of the first motor 41 and the rotation axis of the second motor 43 are perpendicular to each other, and the rotation axis of the second motor 43 and the rotation axis of the third motor 45 form an acute angle.

[0046] It can be understood that the specific structure and working principle of the first motor 41, the second motor 43 and the third motor 45 in the pan-tilt assembly 4 can be obtained by technical personnel in this field based on the prior art, and the structure and working principle of the first motor 41, the second motor 43 and the third motor 45 will not be described in detail here.

[0047] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, the display device 2 includes: a device housing 21, a display screen 22, and a circuit board 23. The device housing 21 is disposed on the connecting seat 46, the display screen 22 is disposed on the device housing 21, and the circuit board 23 is disposed inside the device housing 21.

[0048] It is understandable that the gastroscope of the present application can be powered by an external power supply or a built-in power supply, or a combination of the above two power supply forms. Further, a power supply is provided in the handle portion 11, and the power supply is electrically connected to the pan / tilt assembly 4 and the display device 2.

[0049] Further, such as Figure 3 and Figure 4 As shown, a first infusion tube 122 and a first suction tube 123 are provided in the insertion portion 12 , and the first infusion tube 122 and the first suction tube 123 pass through the end of the insertion portion 12 .

[0050] Further, such as Figure 2 and Figure 4 As shown, the handle portion 11 is provided with a clamp port 111, which is connected to the first suction tube 123, and the clamp port 111 is detachably connected with an end cap 112. When using the gastroscope of the present application, if the medical staff needs to use a clamp to perform a surgical operation on the patient's gastrointestinal tract, the medical staff can insert the clamp into the first suction tube 123 through the clamp port 111. And the end of the first suction tube 123 is extended to perform a surgical operation on the patient's gastrointestinal tract. In addition, the end cap 112 on the clamp port 111 is used to prevent gas or liquid in the first suction tube 123 from leaking.

[0051] Further, such as Figure 3 and Figure 4 As shown, the liquid delivery component 3 includes: a second suction tube 322 and a second infusion tube 321, one end of the second suction tube 322 is connected to the first suction tube 123, and the other end is connected to the accommodating bucket 31, and the accommodating bucket 31 is used to collect liquid sucked out from the patient's stomach and intestines; at least one of the accommodating bucket 31 and the second suction tube 322 is provided with a first water pump 313; one end of the second infusion tube 321 is connected to the first infusion tube 122, and the other end can be connected to a saline bag or other liquid supply component arranged externally, and the second infusion tube 321 is provided with a second water pump 314, and the second water pump 314 is used to pump the liquid in the saline bag or other liquid supply component to the end of the first infusion tube 122, and the cleaning liquid or ordinary physiological saline can be used to clean the display camera 121 or the patient's stomach and intestines.

[0052] It is understandable that a water pump usually pumps water through turbine blades, and the turbine blades can also pump airflow at the same time. Therefore, when using the gastroscope of the present application, if the medical staff needs to operate, the first water pump 313 can also perform suction operation; the second water pump 314 can also perform blowing operation. It is understandable that the specific functions of the first water pump 313 and the second water pump 314 in this embodiment can be obtained by those skilled in the art based on the prior art, and the structure and working principle of the first water pump 313 and the second water pump 314 will not be described in detail here.

[0053] In this embodiment, the second infusion tube 321 and the front section of the second suction tube 322 can be integrated in a connecting pipe, thereby improving the integration of the liquid delivery assembly 3 and making it convenient for medical staff to carry and operate.

[0054] Further, such as Figure 2 and Figure 4 As shown, a pipe connector 113 is provided between the second suction tube 322 and the second infusion tube 321 and the handle portion 11, and the second suction tube 322 and the second infusion tube 321 are detachably connected to the handle portion 11 through the pipe connector 113. The second infusion tube 321 and the second suction tube 322 are respectively connected to the first infusion tube 122 and the first suction tube 123 through the pipe connector 113. Preferably, the pipe connector 113 is fixedly connected to the handle portion 11. Before using the gastroscope, medical staff can use a cleaning tool to extend from the pipe connector 113 into the first infusion tube 122 and the first suction tube 123 for scrubbing. At the same time, a cleaning tool can also be used to extend from one end of the second infusion tube 321 and the second suction tube 322 connected to the pipe connector 113 to clean them.

[0055] Further, such as Figure 6 As shown, a lighting device 124 is provided at the end of the insertion portion 12 .

[0056] It is understandable that the lighting device 124 is used for lighting to make the camera 121 take clearer pictures.

[0057] In summary, the present application provides a visual gastroscope. When medical staff operate the soft endoscope body 1 to adjust the position of the insertion part 12, several motors on the pan-tilt assembly 4 perform angle compensation according to the movement of the soft endoscope body 1, thereby effectively keeping the display device 2 stable and avoiding affecting the medical staff's viewing of the image on the display device 2.

[0058] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
