[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0042] Reference Figures 1-10 As shown, this embodiment of the present invention provides a host controller for an ultrasonic high-frequency surgical device, comprising:

[0043] The front cover assembly 100 includes a front cover housing 110; the rear end of the front cover housing 110 is provided with a notch 120; a plurality of first positioning buckles 130 extending toward the notch 120 are provided on the inner walls around the front cover housing 110.

[0044] The enclosure 200 is sealed to the front cover assembly 100. The enclosure 200 includes a middle frame 210, a rear cover 220, a bottom plate 230, and an outer shell 240. The middle frame 210 and the rear cover 220 are respectively connected to the two ends of the top of the bottom plate 230.

The middle frame 210 includes a vertically arranged main board 211 and a part vertically arranged on top of the main board 211. The top plate 212; the main board 211 has multiple first slots 213 around its perimeter, each first slot 213 corresponding to a first positioning buckle 130, with the first positioning buckle 130 engaging in the first slot 213; the enclosure 200 also includes an intermediate body 250 parallel to the bottom plate 230, a power supply substrate 260 parallel to the middle frame 210 and the rear cover 220, and a 12V power supply 270 and a 48V power supply 280 connected to the power supply substrate 260. The intermediate body 250 is connected to the middle frame 210.

[0045] The elastic cover assembly 300 includes a plurality of elastic elements 310 arranged at equal intervals; the tail end of the elastic element 310 is connected to the housing shell 240; the front end of the elastic element 310 is bent and abuts against the inner wall of the top plate 212, for attaching the top plate 212 to the inner wall of the front cover shell 110.

[0046] Specifically, in this embodiment, a first positioning buckle 130 is provided on the inner wall of the front cover shell 110, and the first positioning buckle 130 engages with the first slot 213 on the middle layer frame 210. During assembly, the first positioning buckle 130 can be used to engage and install the middle layer frame 210 onto the front cover shell 110. The first positioning buckle 130 ensures accurate relative positioning between the middle layer frame 210 and the front cover shell 110, allowing it to be precisely installed in the predetermined position and preventing the host controller from shifting due to vibration or other external forces during use. Furthermore, this is crucial for the alignment of the internal structure and the overall structural stability of the host controller. Secondly, the engagement of the first positioning buckle 130 with the first slot 213 facilitates disassembly, making upgrades and maintenance of internal components more convenient.

[0047] In this embodiment, the front cover shell 110 and the middle frame 210 of the housing 200 are elastically connected using an elastic pressure cap assembly 300. The elastic element 310 can be adjusted in terms of compression as needed to adapt to different installation scenarios with varying gaps, ensuring a tight and adaptable connection. Furthermore, the elastic connection allows for detachment, thus facilitating the installation and removal of the front cover shell 110 and the housing 200, and simplifying equipment maintenance and replacement.

[0048] Furthermore, the end of the elastic member 310 that contacts the front cover assembly 100 is provided with a bend 311. Specifically, the bend 311 is designed to facilitate the elastic member 310 to fit tightly against the middle frame 210, thereby providing effective and reliable support for the middle frame 210.

[0049] Furthermore, the elastic cap assembly 300 also includes a first connector 320 and a second connector 330; multiple elastic elements 310 are connected via the first connector 320 and the second connector 330; the first connector 320 and the second connector 330 are respectively clamped on the upper and lower sides of the tail end of the elastic element 310; the first connector 320, the second connector 330, and the elastic element 310 are respectively provided with connecting holes, and the connecting holes of the three are fixedly connected to the outer shell 240 of the housing by bolts. Specifically, in this embodiment, multiple elastic elements 310 (e.g., 5 elastic elements 310) are fixedly connected as a whole by the first connector 320 and the second connector 330. Then, it is connected to the outer shell 240 of the housing by bolts to stabilize the elastic cap assembly 300. This embodiment facilitates the rapid assembly of the elastic cap assembly 300 onto the housing 200, improving assembly efficiency.

[0050] Furthermore, the rear end face of the bottom of the front cover shell 110 is provided with a plurality of spaced second positioning buckles 140. The second positioning buckles 140 extend from the rear end face of the front cover shell 110 toward the housing 200 to form an extension portion 141. The rear end face of the extension portion 141 is provided with a second slot 142. The top of the front end of the bottom plate 230 is provided with a plurality of positioning posts 231, which are correspondingly arranged with the second slots 142. The positioning posts 231 are engaged in the second slots 142. Specifically, the cooperation between the second slots 142 and the positioning posts 231 in this embodiment ensures that the bottom of the front cover shell 110 is precisely aligned with the bottom plate 230. This ensures that the front cover shell 110 is in the correct position, prevents displacement during assembly, and makes the assembly process faster and simpler. The bottom of the buckles is tightly attached to the bottom of the housing 200, reducing dimensional chain errors and assembly errors. This ensures the accuracy of assembly and the overall performance of the product.

[0051] Furthermore, the front sidewall of the front cover housing 110 is provided with a display area 111, a first operation area 112, and a second operation area 113; the first operation area 112 and the second operation area 113 are located on both sides of the display area 111; the first operation area 112 is used to establish electrical and signal connections between the inside of the housing 200 and external devices. The second operation area 113 is used to control switches. The display area 111 can be a touch screen. Specifically, in this embodiment, the display area 111 is set in the center to achieve the centering of the PLD display panel 1111, improve the appearance of the front cover assembly 100, and make the user experience of the display panel more comfortable. Furthermore, the display area 111 separates the two operation areas (the first operation area 112 and the second operation area 113), achieving a clear division of functional areas and avoiding misoperation.

[0052] Furthermore, the display area 111, the first operation area 112, and the second operation area 113 are all recessed inward from the outer surface of the front sidewall of the front cover 110, and the depth of the recess is different. Specifically, in this embodiment, the first operation area 112 and the second operation area 113 are not on the same plane as the display area 111 (touch screen), thereby visually dividing the area and avoiding accidental operation.

[0053] Furthermore, the display area 111 includes a PLD display panel 1111 and a glass panel 1112, with the glass panel 1112 located inside the PLD display panel 1111. In some embodiments, the glass panel 1112 can be sealed to the PLD display panel 1111 with adhesive. Specifically, the PLD display panel 1111 serves as the host's display and control panel, used to display device status, setting parameters, and other relevant information during the surgical process. The glass panel 1112 achieves a comprehensive upgrade in wear and scratch resistance, safety protection, and optimized display effect, protecting the PLD display panel 1111. Additionally, the glass panel 1112 also provides a certain degree of electromagnetic shielding.

[0054] Furthermore, the PLD display panel 1111 and the glass panel 1112 are connected by multiple thermoplastic nuts 150; the front cover housing 110 and the middle frame 210 are connected by multiple thermoplastic nuts 150.

[0055] Specifically, the hot melt nut 150 melts the hot melt adhesive inside by heating, then fills the threaded hole and forms a dual fixing effect of mechanical connection and adhesion with the threads inside the hole. After the hot melt adhesive cools and solidifies, the nut forms a very strong connection with the threaded hole. Compared to ordinary nuts, using the hot melt nut 150 eliminates the need for drilling holes in the front cover housing 110, reducing material strength loss; furthermore, the hot melt nut 150 provides superior fixing and vibration resistance. By adjusting the height of the hot melt nut 150 and using appropriate shims, a tight fit between the PLD display panel 1111 and the glass panel 1112 can be ensured, simplifying the installation and positioning process, meeting the centering requirements, and ensuring installation stability.

[0056] Furthermore, the second operating area 113 is provided with a button cap 1131 and a button body 1132; the front cover shell 110 is provided with a first mounting hole, and the button cap 1131 is installed in the first mounting hole; the button body 1132 is snapped onto the rear end of the button cap 1131. Specifically, the first mounting hole positions the button cap 1131 to ensure the neatness and aesthetics of the button cap 1131 and its surroundings. In some embodiments, one of the button body 1132 and the button cap 1131 is provided with a boss 1133, and the other is provided with a groove, and the boss 1133 and the groove cooperate to achieve the snap-fit ​​connection between the two. The snap-fit ​​fixed connection between the button body 1132 and the button cap 1131 can reduce the shaking of the button during operation and improve the stability and durability of the button.

[0057] Furthermore, the front surface of the button cap 1131 is recessed from its periphery towards the center to form a concave structure. Specifically, the concave structure allows the finger to be naturally positioned in the center of the button cap 1131, helping the user to confirm that the button has been pressed and providing better tactile feedback.

[0058] Furthermore, the first operating area 112 is provided with two second mounting holes penetrating the front sidewall of the front cover housing 110. The two second mounting holes are respectively fitted with a first aviation socket 1121 and a second aviation socket 1122. The first aviation socket 1121 and the second aviation socket 1122 are used to establish electrical and signal connections between the inside of the enclosure 200 and external devices. One of the first aviation socket 1121 and the second aviation socket 1122 is used for output, and the other for input. Specifically, this embodiment uses the first aviation socket 1121 and the second aviation socket 1122 to establish reliable power, signal, and data connections between the electronic devices inside and outside the enclosure 200. Aviation sockets offer highly reliable connections, enabling stable transmission during complex medical procedures. Furthermore, aviation sockets typically have good sealing properties, preventing dust, moisture, and other harmful substances from entering the enclosure.

[0059] Furthermore, the front end of the second mounting hole is provided with a flange 1123 that protrudes from the outer surface of the front sidewall of the front cover housing 110. Specifically, the flange 1123 makes the socket more conspicuous and facilitates quick plugging.

[0060] Furthermore, the front sidewall of the front cover housing 110 is inclined, and the front sidewall of the front cover housing 110 slopes inward from bottom to top. In some embodiments, the inclination angle of the front sidewall of the front cover housing 110 is 70 degrees to 80 degrees. For example, the inclination angle is 77 degrees. Specifically, this embodiment uses an inclined front cover housing 110, which conforms to ergonomic principles and makes viewing and touch operation more convenient. In actual production, although increasing the slope angle can significantly improve the field of vision, it also increases the difficulty of structural design. This application achieves a balance between ensuring easy installation of internal parts and incorporating ergonomic requirements.

[0061] Furthermore, a sealing groove is provided on the outer wall of the front cover housing 110 on the side with the notch 120, and a sealing ring 160 is provided in the sealing groove. Specifically, in this embodiment, the sealing ring 160 is used to seal the front cover assembly 100 and the housing 200. The sealing ring 160 is located in the sealing groove to prevent the sealing ring 160 from shifting and to ensure the sealing effect. The sealing ring 160 can prevent dust, moisture and other debris from entering the chassis, protecting the internal electronic components from damage. In addition, the sealing ring 160 can also reduce the vibration of the internal components of the chassis, thereby reducing noise. Secondly, the sealing ring 160 can also play an electromagnetic shielding role, reducing the leakage of electromagnetic interference (EMI) generated by the electronic equipment inside the chassis to the outside, or preventing external electromagnetic interference from entering the chassis. The material of the sealing ring 160 usually needs to have good elasticity, corrosion resistance, temperature resistance and a certain degree of chemical stability. Therefore, in some embodiments, the sealing ring 160 is made of natural rubber, which has the characteristics of resistance to low and high temperatures and various chemicals.

[0062] In some comparative embodiments, the outer shell 240 and the front cover shell 110 are often connected by a double stop. Although the double stop connection can provide better limiting and sealing effects, it usually requires a material thickness of more than 2.5mm, which is a relatively high requirement. Therefore, to solve this problem, a single stop 170 is provided on the outer wall of the front cover shell 110 with a tail end; the front end of the bottom plate 230 and the front end of the outer shell 240 are inserted into the single stop 170. The sealing groove is located in the middle of the single stop 170. Specifically, this embodiment adopts a single stop 170 design, which not only optimizes the product structure, but also allows the outer shell 240 to be more smoothly embedded into the shell 200 when the sheet metal parts (all parts in this application are made of sheet metal) are small, reducing the requirements for sheet metal tolerances and further improving the rationality of the design. In addition, the single stop 170 design can control the step difference within a very small range in appearance, so it is also called a sealing stop structure. The sealing ring 160 also serves a waterproof and dustproof function in this structure. The single stop 170 design not only helps to close the gap between the housings, but without the single stop 170 structure, the gap between the housings (box outer shell 240 and front cover outer shell 110) may be uneven. Even if the function is not affected, it will look lower-end and affect the product quality. If the gap is too large, it may even expose internal components. In addition, the single stop 170 structure also acts as a limit, preventing or reducing the misalignment or step difference between the two housings during assembly, thereby improving the overall assembly accuracy and product aesthetics.

[0063] Furthermore, the four corners of the front cover shell 110 are rounded. In some embodiments, the rounded corner radius is approximately 20mm. This rounded corner treatment in this embodiment ensures an aesthetically pleasing appearance while also cleverly adjusting the internal space, achieving design harmony.

[0064] Furthermore, reinforcing ribs 180 are provided around the inner wall of the front cover housing 110. Specifically, the reinforcing ribs provided in this embodiment can enhance the overall strength and stability, effectively preventing deformation and damage under external pressure or impact; at the same time, they reduce the risk of cracking by dispersing stress, thereby protecting internal components from damage and improving the durability and service life of the product. In some embodiments, the reinforcing ribs 180 adopt an avoidance design to prevent interference between the reinforcing ribs 180 and other parts inside the front cover housing 110, ensuring the structural integrity of the product.

[0065] The structure of this application is more reasonable, the positioning operation is more convenient, and the assembly process is simplified and easy.

[0066] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
