Detailed implementation mode

[0016] In order to enable those skilled in the art of this technology to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0017] See Figures 1-10 , a high-frequency electrocautery instrument with a flip screen, including a chassis 1, a mobile base 2 and a flip screen assembly 3. The lower end of the chassis 1 is fixedly connected to the mobile base 2, and the upper end of the chassis 1 is equipped with the flip screen assembly 3. 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. The chassis connection assembly 34 is movably connected to the chassis 1.

[0018] Furthermore, the screen assembly 31 includes a screen housing 311, a screen body 312 and a screen backplane 313. One side of the screen backplane 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 screen assembly and being electrically connected to the chassis 1, which is convenient for observing and controlling the working parameters of the device.

[0019] Furthermore, a square notch is opened below the screen backplane.

[0020] Further, 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 slideway 325, and a fixing tooth plate 326. A middle frame groove 322 is provided in the middle of the fixing plate body 321. A first stud base 323 is fixedly connected to the left end face of the middle frame groove 322. There are three groups of the first stud bases 323 arranged from top to bottom on the same axis. A second stud base 324 is provided below the second group of the first stud bases 323. A slideway 325 is formed in the middle of the middle frame groove 322. A fixing tooth plate 326 is provided on the right end face of the middle frame groove 322.

[0021] Further, the angle control component 33 includes a dial 331, a fixed hook 332, a tension spring 333, an inclined sleeve hole 334, a clamping groove 335, a positioning rack 336, a fixed buckle 337, and a rack pressing plate 338. A fixed hook 332 is fixedly connected to the middle of the left side of the dial 331. One end of the tension spring 333 is connected to the fixed hook 332. The other end of the tension spring 333 is fixedly connected to the second stud base 324 by a screw and maintains tension. An inclined sleeve hole 334 is formed in the left end face of the dial 331. There are three groups of the inclined sleeve holes 334, and the three groups of inclined sleeve holes 334 correspond to the first stud bases 323 one by one. The dial 331 is slidably connected to the fixing plate body 321 by sleeving the first stud base 323 through the inclined sleeve hole 334. A clamping groove 335 is formed in the right end face of the dial 331. The clamping groove 335 is slidably connected to the positioning rack 336. The positioning rack 336 is in an "L" shape. The right side of the positioning rack 336 is provided with saw teeth and corresponds to the fixing tooth plate 326. A square sliding hole is formed in the middle of the positioning rack 336. The fixed buckle 337 is in an "n" shape. The fixed buckle 337 is fixedly connected to the upper connecting rod 341 by a screw passing through the square sliding hole formed in the middle of the positioning rack 336. The rack pressing plate 338 is fixedly connected to the middle frame groove 322 by a screw. Thus, by pulling down the dial 331, the dial 331 moves obliquely downward. At the same time, the positioning rack 336 slidably connected to the surface of the dial 331 through the clamping groove 335 is driven to move horizontally, so that the positioning rack 336 is separated from the fixing tooth plate 326, so that the positioning rack 336 can slide arbitrarily in the clamping groove 335 of the dial 331. When the force on the dial 331 is paused, the dial 331 is pulled back to its original position by the tension spring 333, so that the positioning rack 336 is engaged with the fixing tooth plate 326 to form a fixed state, achieving a locking effect.

[0022] Furthermore, the chassis connection assembly 34 includes an upper connecting rod 341, a round pin threaded column 342, a lower connecting rod 343, a cylindrical pin 344, a rotary fixing seat 345, a screen rotating shaft 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 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. Both sides of the upper connecting rod 341 are rotatably connected to the lower connecting rod 343 through the round pin threaded column 342. The lower connecting rod 343 is rotatably connected to the rotary fixing seat 345 through the cylindrical pin 344. The rotary 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 slideway 325 along with the positioning rack 336 through the cylindrical stud base on one side of it. At the same time, in cooperation with the rotatably connected lower connecting rod 343 and rotary fixing seat 345, the fixing plate 32 is connected to the chassis 1.

[0023] Furthermore, one end of the hinge 347 is fixedly connected to one side of the top of the screen rotating shaft connecting block 346. There are two groups of hinges 347. The other end of the hinge 347 passes through the connection hole above the fixing plate body 321 and is fixedly connected to the screen back plate 313 by screws. The screen rotating shaft connecting block 346 and the screen back plate 313 form a rotary connection. The screen rotating shaft connecting block 346 is fixedly connected to one side of the top of the chassis 1 by screws. Thus, the screen back plate 313 and the fixing plate body 321 fixedly connected to it by screws can be flipped around the chassis 1 around the hinge 347. The design of this rotating structure improves the usability of the device.

[0024] As can be seen from the above technical solutions, during use, first, the high-frequency electrocautery instrument is pushed to the required working position by using the mobile base 2. Then, according to the operation requirements of medical staff, by pulling down the dial 331 in the angle control assembly 33, it moves obliquely downward around the first stud base 323 along the oblique movement track of the oblique sleeve hole 334. At the same time, the positioning rack 336 slidably connected to the surface of the dial 331 through the card slot 335 is driven to move horizontally, so that the positioning rack 336 is separated from the fixed tooth plate 326. Thus, the positioning rack 336 can slide arbitrarily in the card slot 335 of the dial 331, and then the lower connecting rod 343 can be driven to rotate around the rotary fixing seat 345, realizing arbitrary adjustment of the angle of the screen assembly 31 around the chassis 1. When the force on the dial 331 is paused, the dial 331 is pulled back to its original position by the tension spring 333, so that the positioning rack 336 meshes with the fixed tooth plate 326 to form a fixed state, achieving a locking effect. In this way, the use of a high-frequency electrocautery instrument with a flipable screen is completed.
