DETAILED DESCRIPTION

[0034] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0036] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0037] Reference Figures 1 to 5 The electronic hysteroscope disclosed in this embodiment includes: an insertion tube 10 and a shell 20; the shell 20 includes a body 21 and a handle 22, the handle 22 is connected to one end of the body 21, and the handle 22 and the body 21 are arranged at an obtuse angle, the diameters of the two ends of the handle 22 are larger than the diameter of the middle part, and the two ends of the handle 22 and the middle part are both arc-shaped transitions;

[0038] One end of the insertion tube 10 is used as an insertion end to enter the human body cavity, and the other end is used as a fixed end to be connected to the other end of the main body 21 .

[0039] The shell 20 is composed of a main body 21 and a handle 22. The handle 22 is a part for the doctor to hold and operate. In particular, the connection between the handle 22 and the main body 21 is set at an obtuse angle. The doctor can hold the handle 22 obliquely and control the angle and depth of the insertion tube 10 entering the human body cavity through fine wrist movements. Compared with the horizontal or vertical grip design of traditional electronic hysteroscopes, it is more ergonomic and can reduce wrist, arm or shoulder fatigue caused by long-term surgical operations; further, the diameters of both ends of the handle 22 are larger than the diameter of the middle part. Such a design provides a better gripping feeling and anti-slip effect when holding. At the same time, the two ends of the handle 22 and the middle part are in an arc-shaped transition, which further improves the grip comfort and operating performance of the handle 22, reduces the physical burden of doctors during long-term operations, and improves surgical accuracy and patient safety.

[0040] Reference Figure 2 and Figure 3 The insertion tube 10 includes a sleeve 11 and a clamp channel tube 12. The main part of the clamp channel tube 12 is arranged in the sleeve 11, and the clamp channel tube 12 is used to guide other instruments (such as biopsy forceps, etc.) into the human body cavity for observation and treatment; the fixed end of the sleeve 11 is connected to a fixing seat 30, and the fixed end of the sleeve 11 is fixed in the main body 21 through the fixing seat 30; the fixed end of the clamp channel tube 12 is longer than the fixed end of the sleeve 11, and the fixed end of the clamp channel tube 12 is connected to an adapter 40, and an instrument channel 41 is opened in the adapter 40. One end of the instrument channel 41 is connected to the clamp channel tube 12, and the other end is connected to the outside world. The instrument channel 41 inside the adapter 40 provides a direct path from the clamp channel tube 12 to the outside world for surgical instruments to enter and exit, which means that instruments can directly enter the body through this instrument channel 41 to achieve the purpose of inspection or treatment.

[0041] Reference Figure 2 and Figure 3 The electronic hysteroscope also includes a plunger 50, which is detachably connected to the other end of the instrument channel 41. The detachability of the plunger 50 means that it can be attached to the opening of the instrument channel 41 when needed, or removed when not needed. This design provides operational flexibility and versatility. The plunger 50 can be inserted into the instrument channel 41 to achieve a seal. When no surgical tools are used, the plunger 50 can prevent the perfused liquid or liquid and debris in the surgical area from flowing out of the instrument channel 41. In some cases, hysteroscopic surgery may need to be performed under specific pressure conditions, and the plunger 50 can help maintain the pressure in the uterine cavity, for example, by closing the instrument channel 41 to maintain internal pressure during perfusion.

[0042] Reference Figure 3The diameter of the main part of the instrument channel 41 is larger than the inner diameter of the clamp channel tube 12, and the diameter of the instrument channel 41 is designed to be as large as possible to facilitate the insertion of other instruments (such as biopsy forceps, etc.) into the instrument channel 41; the connection between the instrument channel 41 and the clamp channel tube 12 is tapered, and this tapered design can provide a gradually narrowing transition, which helps to guide other instruments to smoothly enter the narrower clamp channel tube 12 from the wider instrument channel 41; and the axis of the instrument channel 41 coincides with the axis of the clamp channel tube 12, ensuring that after other instruments enter the instrument channel 41, they can enter the clamp channel tube 12 in a straight line, reducing friction or difficulty in operation caused by misalignment. Axis alignment can also help doctors to accurately control surgical tools because the movement path of the tools is consistent and predictable.

[0043] Reference Figure 3 The side wall of the adapter 40 is provided with a water inlet channel 61 and a water outlet channel 71; the water inlet channel 61 is connected to a water inlet pipe 62, which is connected to an irrigation water pump through an inlet valve 63, and is used to inject cleaning fluid or other liquids into the uterine cavity to clean the surgical area, improve the clarity of the field of vision or promote the separation of tissues; the water outlet channel 71 is connected to a water outlet pipe 72, which is connected to a negative pressure device through an outlet valve 73, and is used to extract the liquid in the uterine cavity, which can be used to extract blood, tissue fragments or cleaning fluid generated during the operation.

[0044] Reference Figure 3 , the water outlet channel 71 is arranged between the water inlet channel 61 and the tapered connection of the clamp channel tube 12. This layout helps to efficiently remove the liquid in the surgical area, while ensuring that the injected cleaning fluid can be immediately aspirated, thereby improving the cleaning efficiency. During surgery, a good field of vision is crucial. The location of the water outlet channel 71 allows the cleaning fluid to be immediately removed in the field of vision, ensuring a clear field of vision for the doctor and avoiding the accumulation of excessive perfusion fluid in the surgical area, which may affect the surgical operation or increase the risk of infection.

[0045] Reference Figure 3 The water inlet pipe 62 and the water outlet pipe 72 are both arranged in the handle part 22. This design can reduce the exposure of the pipeline to avoid accidentally hanging or pulling the pipeline during operation, and also makes the appearance and feel of the equipment more compact and neat; the water inlet valve 63 and the water outlet valve 73 are both fixed at the end of the handle part 22 away from the main body 21. From the perspective of ergonomics, such a setting allows the doctor or surgical staff to directly operate the valve by hand without releasing the hysteroscope handle. The doctor can quickly adjust the water injection or suction while keeping the instrument operating posture unchanged, which helps to maintain high efficiency and reduce interference during the operation.

[0046] Reference Figure 4 and Figure 5The insertion end of the sleeve 11 is connected to a head end seat 80, which is provided with a clamp channel hole 81, an image acquisition hole 82 and an illumination device installation hole 83. The clamp channel hole 81 is connected to the clamp channel tube 12 to guide the surgical instrument into the uterine cavity for operation; a first gap 13 is left between the sleeve 11 and the clamp channel tube 12, and the image acquisition hole 82 and the illumination device installation hole 83 are connected to the first gap 13; a camera is installed in the image acquisition hole 82 to capture the situation in the uterine cavity and transmit the image to an external monitor or display; an LED lamp is installed in the illumination device installation hole 83 to provide necessary illumination so as to more clearly observe and record the view in the uterine cavity. The first gap 13 provides installation space for the cables of the camera and the LED lamp, and can also serve as a heat dissipation space for the illumination device.

[0047] Reference Figure 5 In the radial section of the head end seat 80, the center of the clamp channel hole 81 is set lower than the center of the head end seat 80, and the image acquisition hole 82 is set above the clamp channel hole 81; the clamp channel hole 81 is connected to the sinking tube 90, and the clamp channel hole 81 is connected to the clamp channel tube 12 through the sinking tube 90, and the gap between the sinking tube 90 and the upper part of the sleeve 11 is larger than the gap between the sinking tube 90 and the lower part of the sleeve 11. Since the diameter of the head end seat 80 needs to be as small as possible to facilitate insertion and reduce patient discomfort, and the clamp channel hole 81 needs to be as large as possible to facilitate the passage of surgical instruments, while leaving installation space for the camera and LED lamp, the design of the sinking tube 90 allows the space to be effectively arranged inside the narrow head end seat 80, and by establishing an asymmetric gap between the clamp channel hole 81 and the sleeve 11, while leaving installation space for the camera and LED lamp, as large a space as possible is created for the clamp channel hole 81.

[0048] Reference Figure 5 , an illumination device mounting hole 83 is provided on both sides of the symmetry axis of the clamp hole 81 and the image acquisition hole 82. Such a symmetrical layout means that the illumination light source is evenly distributed on both sides of the camera to provide balanced illumination, eliminate or reduce shadows, and thus obtain higher quality images.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
