[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] Referring to Figures 1-10, a high-frequency electrocautery device with a flip-screen includes a chassis 1, a movable base 2, and a flip-screen assembly 3. The movable base 2 is fixedly connected to the lower end of the chassis 1, and the flip-screen assembly 3 is installed on the upper end of the chassis 1. The flip-screen assembly 3 includes a screen assembly 31, a fixing plate 32, an angle control assembly 33, and a chassis connection assembly 34. The screen assembly 31 is threadedly connected to the fixing plate 32. The angle control assembly 33 is installed inside the fixing plate 32. The chassis connection assembly 34 is installed on the back of the fixing plate 32 and is movably connected to the chassis 1.

[0029] Furthermore, the screen assembly 31 includes a screen housing 311, a screen body 312, and a screen back panel 313. One side of the screen back panel 313 is fixedly connected to the screen housing 311 by screws, and the screen body 312 is fixedly connected to the inside of the screen housing 311 by screws, forming a display assembly and electrically connected to the chassis 1, which facilitates the observation and control of the device's operating parameters.

[0030] Furthermore, a square notch is provided at the bottom of the screen back panel.

[0031] Furthermore, the fixing plate 32 includes a fixing plate body 321, a middle frame groove 322, a first stud base 323, a second stud base 324, a slide rail 325, and a fixing toothed plate 326. The middle frame groove 322 is provided in the middle of the fixing plate body 321. The first stud base 323 is fixedly connected to the left side of the end face of the middle frame groove 322. Three sets of the first stud base 323 are arranged from top to bottom on the same axis. The second stud base 324 is provided below the second set of first stud base 323. The slide rail 325 is opened in the middle of the middle frame groove 322. The fixing toothed plate 326 is provided on the right side of the end face of the middle frame groove 322.

[0032] Furthermore, the angle control component 33 includes a lever 331, a fixed hook 332, a tension spring 333, an angled sleeve hole 334, a slot 335, a positioning rack 336, a fixing buckle 337, and a rack pressure plate 338. The fixed hook 332 is fixedly connected to the middle left side of the lever 331. The fixed hook 332 is connected to one end of the tension spring 333. The other end of the tension spring 333 is fixedly connected to the second stud base 324 by screws and maintains tension. A beveled sleeve hole 334 is provided on the left side of the end face of 331. Three sets of beveled sleeve holes 334 are provided, each corresponding to a first stud base 323. The lever plate 331 is slidably connected to the first stud base 323 and the fixing plate body 321 through the beveled sleeve holes 334. A slot 335 is provided on the right side of the end face of the lever plate 331. The slot 335 slidably connects to a positioning rack 336, which is L-shaped. The right side of the positioning rack 336 is provided with serrations corresponding to the fixed toothed plate 326. A square sliding hole is opened in the middle of the positioning rack 336. The fixing buckle 337 is "n" shaped. The fixing buckle 337 is fixedly connected to the upper connecting rod 341 by screws passing through the square sliding hole in the middle of the positioning rack 336. The rack pressure plate 338 is fixedly connected to the middle frame groove 322 by screws. Thus, by pulling down the lever plate 331, the lever plate 331 moves diagonally downward. At the same time, the positioning rack 336, which is slidably connected to the surface of the lever plate 331 through the slot 335, is driven to move laterally, so that the positioning rack 336 separates from the fixed toothed plate 326. This allows the positioning rack 336 to slide freely in the slot 335 of the lever plate 331. When the force applied to the lever plate 331 is stopped, the lever plate 331 is pulled back to its original position by the tension spring 333, so that the positioning rack 336 and the fixed toothed plate 326 are engaged to form a fixed state, achieving a locking effect.

[0033] Furthermore, the chassis connection assembly 34 includes an upper connecting rod 341, a round pin threaded post 342, a lower connecting rod 343, a cylindrical pin 344, a rotating fixing seat 345, a screen hinge connecting block 346, and a hinge 347. The cylindrical stud base on the left side of the upper connecting rod 341 protrudes from the left side plane of the upper connecting rod 341 and its diameter is smaller than the width of the square sliding hole opened in the middle of the positioning rack 336. The upper connecting rod 341 is rotatably connected to the lower connecting rod 343 on both sides through the round pin threaded post 342. The lower connecting rod 343 is rotatably connected to the rotating fixing seat 345 through the cylindrical pin 344. The rotating fixing seat 345 is fixedly connected to the chassis 1. After the positioning rack 336 is unlocked, the upper connecting rod 341 can slide in the slide rail 325 through the cylindrical stud base on one side of it along with the positioning rack 336. At the same time, it cooperates with the rotatably connected lower connecting rod 343 and rotating fixing seat 345 to realize the connection between the fixing plate 32 and the chassis 1.

[0034] Furthermore, one end of the hinge 347 is fixedly connected to the top side of the screen hinge connecting block 346. Two sets of hinges 347 are provided. The other end of the hinge 347 passes through the connecting hole above the fixing plate body 321 and is fixedly connected to the screen back plate 313 by screws. The screen hinge connecting block 346 and the screen back plate 313 form a rotatable connection. The screen hinge connecting block 346 is fixedly connected to the top side of the chassis 1 by screws. This allows the screen back plate 313 and the fixing plate body 321 fixed to it by screws to rotate around the hinge 347 around the chassis 1. This rotating structure design improves the ease of use of the device.

[0035] As can be seen from the above technical solution, in use, firstly, the high-frequency electrocautery device is pushed to the required working position using the movable base 2. Then, according to the operational needs of medical personnel, the lever 331 in the angle control component 33 is pulled downwards, causing it to move obliquely downwards around the first stud base 323 through the oblique movement trajectory of the oblique sleeve hole 334. At the same time, the positioning rack 336, which is slidably connected to the surface of the lever 331 through the slot 335, is driven to move laterally, causing the positioning rack 336 to engage with the fixed toothed plate 3. 26 is separated, allowing the positioning rack 336 to slide freely within the slot 335 of the dial plate 331, thereby driving the lower connecting rod 343 to rotate around the rotating fixed seat 345, enabling the screen assembly 31 to adjust its angle arbitrarily around the chassis 1. When the force applied to the dial plate 331 is stopped, the dial plate 331 is pulled back to its original position by the tension spring 333, causing the positioning rack 336 to mesh with the fixed toothed plate 326 to form a fixed state, achieving a locking effect. This completes the use of a high-frequency electrocautery device with a screen that can be flipped.
