[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] like Figures 1 to 7As shown, an embodiment of the present invention discloses an endoscope system, including a display 3000, an endoscope 7 and a host 1000. The display 3000 has a resolution greater than 3K. The endoscope 7 is electrically connected to the host 1000. The host 1000 includes a housing and a power supply assembly 24.

[0040] The housing has a cavity inside. The housing includes a front shell 13 and a rear shell 3 arranged opposite to each other in a first direction. The housing also includes a first side shell 35 and a second side shell 36 arranged opposite to each other in a second direction. The first direction is perpendicular to the second direction.

[0041] The power supply assembly 24 is disposed in the cavity and adjacent to the first side shell 35. The power supply assembly 24 includes a power support 241, a power board 243 and a power shield 244 arranged sequentially along the third direction. The power shield 244 is detachably connected to the power support 241 and the power shield 244 and the power support 241 define an installation cavity. The power board 243 is detachably disposed in the installation cavity. The third direction is perpendicular to both the first direction and the second direction.

[0042] To make the technical solution of this application easier to understand, the technical solution of this application is further described below using the following examples: the first direction is consistent with the front-back direction, the second direction is consistent with the left-right direction, and the third direction is consistent with the up-down direction. The front-back direction, left-right direction, and up-down direction are as follows: Figure 1 As shown.

[0043] The resolution of the monitor 3000 is greater than 3K; for example, the resolution of the monitor 3000 is 4K.

[0044] The display 3000 is used to display the images captured by the endoscope 7. The endoscope 7, camera handle 5, and camera cable 6 are connected in sequence. The other end of the camera cable 6 is connected to the host 1000. One end of the beam guide 8 is connected to the LED light source 2000, and the other end is connected to the endoscope 7, responsible for transmitting the light source.

[0045] The first side shell 35 is located to the left of the second side shell 36. The shell also includes a bottom shell 2 and an upper shell 4. The front shell 13, the rear shell 3, the bottom shell 2, the first side shell 35 and the second side shell 36 together define the inner cavity. The upper shell 4 is located on the upper part of the bottom shell 2.

[0046] The power supply assembly 24 is located within the cavity and is detachably connected to the first side shell 35, for example, by bolting or snap-fitting.

[0047] The power supply bracket 241 is located at the bottom, serving as the physical support foundation for the entire power supply assembly 24. The power board 243 is located above the power supply bracket 241 and is responsible for providing a stable power supply to the entire endoscope 7 system. At the top is the power supply shield 244, which not only protects the power board 243 from external electromagnetic interference but also prevents the electromagnetic radiation generated by the power board 243 from affecting other sensitive electronic components.

[0048] The power shield 244 and the power bracket 241 are connected by bolts or snap-fits and other detachable means. Together they define a closed mounting cavity, and the power board 243 is detachably installed in this mounting cavity.

[0049] Optionally, the power supply bracket 241 is provided with a positioning groove, and the power supply shield 244 is provided with a positioning point. During assembly, the positioning point is snapped into the positioning groove to facilitate assembly.

[0050] The power supply assembly 24 can be pre-assembled and then installed as a whole into the cavity. This modular installation method not only improves installation efficiency but also facilitates later maintenance and repair.

[0051] In the endoscopic system of this embodiment, the power supply component 24 adopts a multi-layer structure design, including a power support 241 at the bottom, a power board 243 in the middle, and a power shield 244 at the top. This layered structure not only optimizes internal space utilization and achieves a highly integrated design, reducing the space occupied by the power supply component 24 and making the internal structure of the host 1000 more compact, but also achieves effective electromagnetic isolation between the power board 243 and other circuits, significantly reducing electromagnetic interference and ensuring the accuracy of the acquired images. Furthermore, the display 3000 is high-resolution, further improving the clarity of the displayed images, thereby enhancing image accuracy and enabling doctors to perform operations accurately.

[0052] Therefore, the endoscope system of this utility model has the advantages of high integration and high image accuracy.

[0053] In some embodiments, the endoscope system includes a control module and an encoding module, which are integrated on the same circuit board 22, which is disposed within a cavity.

[0054] For example, a highly integrated design is achieved by integrating the control module and the encoding module onto the same circuit board 22. This single-board solution reduces the number of connecting cables and interfaces between multiple independent circuit boards 22, simplifies the overall structure of the circuit board 22, reduces potential points of failure, and improves the reliability of the endoscope system.

[0055] In some embodiments, the endoscope system includes a touch screen assembly 15, which includes a touch screen 152 and a touch screen adapter plate 21. The touch screen 152 is disposed on the front shell 13, and the touch screen adapter plate 21 is disposed in the cavity. The touch screen 152 is electrically connected to the control module through the touch screen adapter plate 21. The touch screen adapter plate 21 is detachably disposed at the angle between the front shell 13 and the second side shell 36.

[0056] For example, the touchscreen 152 is located on the right side of the front shell 13, and the touchscreen adapter plate 21 is located at the angle between the front shell 13 and the second side shell 36, i.e., at the front right of the inner cavity. This ensures that the signal transmission path between the touchscreen 152 and the touchscreen adapter plate 21 is minimized, resulting in shorter wiring length. The touchscreen adapter plate 21 is snapped or bolted to the bottom shell 2, making the maintenance and replacement of the touchscreen adapter plate 21 more convenient.

[0057] In some embodiments, an insulating film 242 is provided between the power board 243 and the power bracket 241.

[0058] For example, the insulating film 242 can prevent short circuits between the power board 243 and the power bracket 241, thereby improving the safety and stability of the endoscope system.

[0059] In some embodiments, the power supply bracket 241 is provided with a plurality of spaced-apart fasteners, and the power board 243 and the insulating film 242 are each provided with a plurality of through holes, and the fasteners are inserted into the corresponding through holes.

[0060] Both the power board 243 and the insulating film 242 have multiple through holes, which correspond to the fixing members on the power bracket 241. The fixing members pass through the corresponding through holes, and the power board 243 and the insulating film 242 are firmly fixed to the power bracket 241 by threaded connection or other fixing methods. The endoscope system of this embodiment not only ensures the tight connection of the internal components of the power assembly 24, but also provides good electrical isolation to prevent short circuits and other electrical faults.

[0061] In some embodiments, the power shield 244 is provided with a first cable management hole, which is located on the side of the power shield 244 adjacent to the front shell 13. The front shell 13 is provided with a power button, which is connected to the power board 243 through a first wire. The first cable management hole is used to fix the first wire.

[0062] The power shield 244 has a second cable management hole on the side adjacent to the second side shell 36. The control module and the power board 243 are connected through a second wire, and the second cable management hole is used to fix the second wire.

[0063] For example, a first cable management hole is located on the front edge of the power shield 244 to secure the first wire. When the user presses the power button, a signal is transmitted through the first wire to the power board 243, triggering the start or stop of the endoscope system. A second cable management hole is located on the right edge of the power shield 244 to secure the second wire.

[0064] The endoscope system of this embodiment optimizes the arrangement of the wire path by placing the first wire guide hole and the second wire guide hole on different sides of the power shield 244. This layout keeps the first and second wires as far apart as possible, reducing mutual interference between them.

[0065] In some embodiments, the front housing 13 is provided with an aviation head 14, which is electrically connected to the endoscope 7. A sensor access board 23 is provided in the cavity, which is electrically connected to the endoscope 7 through the aviation head 14, so as to transmit the image information collected by the endoscope 7 to the encoding module.

[0066] For example, the endoscope 7 captures images inside the body via a camera at its front end and converts these optical signals into electrical signals. These electrical signals are then transmitted to the air head 14 via a dedicated camera cable 6, and the air head 14 transmits the signals to the sensor access board 23 located inside the host 1000. The sensor access board 23 is responsible for receiving these image data, converting them into digital signals, and then transmitting them to the encoding module via internal circuitry. The encoding module processes these digital signals, such as through compression and format conversion, ultimately generating a high-quality image that can be clearly displayed on the monitor 3000. This process ensures a high degree of accuracy and consistency at every stage from image acquisition to display.

[0067] In some embodiments, a front fender 252 is provided on the side of the front housing 13 adjacent to the rear housing 3, and a data signal access component 19 is provided on the side of the front housing 13 adjacent to the front fender 252. The data signal access component 19 is electrically connected to the control module. The data signal access component 19 includes a data access board 193, a data board overlapping sheet metal 191 and a conductive foam 192 arranged sequentially in a first direction. The data access board 193 is disposed adjacent to the front housing 13 relative to the conductive foam 192, and a data interface is provided on the data access board 193.

[0068] The data signal access component 19 is detachably mounted on the rear side of the front housing 13, for example, by bolting or snapping it to the front housing 13. The data access board 193 is provided with various data interfaces, such as USB or HDMI interfaces.

[0069] The data board overlap sheet metal 191 is located between the data access board 193 and the conductive foam 192, serving a supporting and fixing function. The data board overlap sheet metal 191 is mounted on the front shell 13 by screws or other fixing methods to ensure the stability of the data access board 193. At the same time, it also provides additional mechanical protection to prevent the data access board 193 from being damaged by external impacts.

[0070] The conductive foam 192 overlaps with the rear side of the sheet metal 191, closely adhering to the bottom shell 2 or the front fender 252. The conductive foam 192 effectively absorbs and shields electromagnetic interference, ensuring the pure transmission of data signals.

[0071] In some embodiments, the flight head 14, the data signal access component 19, and the touch screen 152 are arranged sequentially in the second direction. The flight head 14 is arranged adjacent to the first side shell 35 relative to the touch screen 152. The shell includes a bottom shell 2, which is detachably connected to the front shell 13. The angle between the front shell 13 and the bottom shell 2 is 70 degrees to 85 degrees.

[0072] For example, the aircraft head 14, data signal access component 19, and touch screen 152 are arranged in sequence from left to right, and the bottom shell 2 is bolted or snapped to the front shell 13.

[0073] The angle between the front shell 13 and the bottom shell 2 is 70-85 degrees, for example, 75 degrees, 80 degrees or 85 degrees.

[0074] The endoscope system of this utility model has a tilted front shell 13 design, which makes the interface of the front shell 13 more ergonomic, making it easier to insert or remove the aviation head 14 or press the button, and reducing fatigue caused by long-term operation.

[0075] In some embodiments, the front fender 252 is provided with a first wiring hole 2521, a second wiring hole 2522, and a third wiring hole 2523 arranged sequentially in a second direction. Wires connecting the aircraft head 14 and the sensor access board 23 pass through the first wiring hole 2521. Wires connecting the data access board 193 and the control module pass through the second wiring hole 2522. Wires connecting the touch screen 152 and the touch screen adapter board 21 pass through the third wiring hole 2523.

[0076] For example, the first wire hole 2521, the second wire hole 2522 and the third wire hole 2523 are arranged sequentially from left to right. Thus, the layout of the internal wires can be optimized by using the first wire hole 2521, the second wire hole 2522 and the third wire hole 2523, and the tangling between the wires can be avoided.

[0077] Optionally, the front housing 13 is provided with an interface mounting bracket 16, which is used to fix the aircraft head 14.

[0078] Optionally, the touchscreen assembly 15 also includes a dustproof foam 151, a support foam 153, and a screen support bracket 154. The dustproof foam 151, touchscreen 152, support foam 153, and screen support bracket 154 are arranged sequentially from front to back.

[0079] The dustproof foam 151 is located at the front end of the touch screen assembly 15, effectively blocking external dust, particles and other pollutants from falling onto the surface of the touch screen 152.

[0080] The support foam 153 is located behind the touchscreen 152 and serves a dual purpose. First, it is evenly distributed between the touchscreen 152 and the screen support bracket 154, ensuring that the pressure on the touchscreen 152 is evenly distributed during installation and preventing deformation or damage caused by excessive localized stress. Second, the support foam 153 has a certain degree of elasticity, which can cushion the device when it is subjected to vibration or impact, reducing mechanical stress on the touchscreen 152 and extending its service life.

[0081] The screen support bracket 154 is located at the innermost layer of the touch screen assembly 15 and is fixed to the front shell 13 or the front fender 252, providing a robust mechanical support for the entire touch screen assembly 15. It not only bears the weight of the touch screen 152, but also ensures that the touch screen 152 remains stable during device operation and does not wobble or shift.

[0082] In some other embodiments, the touch screen assembly 15 also includes a touch screen mounting bracket 17 for connecting the screen support bracket 154 and the front fender 252, and the touch screen assembly 15 can be mounted on the front fender 252 using the touch screen mounting bracket 17.

[0083] In some other embodiments, a bottom shell sub-plate 251 is provided above the bottom shell 2, and the bottom shell sub-plate 251, the front fender 252, the first side shell 35, the second side shell 36, the rear shell 3 and the upper shell 4 together form an inner cavity.

[0084] The bottom shell 251, front fender 252, upper shell 4 and rear shell 3 are made of conductive material and connected to the ground wire, thereby preventing the devices contained inside the shell from being subjected to electromagnetic interference, so as to improve the accuracy of the images acquired by the endoscope 7.

[0085] In other embodiments, the rear housing 3 is provided with an AC power terminal 33 and a potential equalization terminal 34, etc., for connecting various external devices. The wire connecting the AC power terminal 33 passes through the fourth wiring hole 2524 reserved in the front fender 252.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
