DETAILED DESCRIPTION

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This invention provides an easy-to-use ablation electrode dissecter, including a connecting base 3 and two forceps 1 connected to the connecting base 3. Electrode heads 2 are connected to the ends of the forceps 1. The forceps 1 are connected to an adjustment mechanism for adjusting the pinching force between the two forceps 1. The adjustment mechanism includes two sliding blocks 4, two arc-shaped rods 11, an arc-shaped sleeve 13, and a second spring 14. The sliding blocks 4 are movably connected to the forceps 1. One end of the arc-shaped rod 11 is inserted into the arc-shaped sleeve 13, and the other end is connected to the sliding block 4. Both ends of the second spring 14 are connected to the two arc-shaped rods 11. The connecting base 3 is connected to a driving mechanism for driving the arc-shaped sleeve 13 to move.

[0020] During normal use, spring 14 is compressed, providing a certain pinching force between the two tweezers 1. When the pinching force needs to be increased, the rotating cylinder 10 drives the stud 12 downward, simultaneously moving the arc-shaped sleeve 13 downward, and the two sliding blocks 4 also downward. At this time, spring 14 is gradually compressed, thereby increasing the pinching force. When the pinching force needs to be decreased, the rotating cylinder 10 drives the stud 12 upward, simultaneously moving the arc-shaped sleeve 13 upward, and the two sliding blocks 4 also upward. Spring 14 gradually returns to its original position, thereby reducing the pinching force. This adjustment can be made according to the usage habits of different medical personnel, making it highly adaptable.

[0021] One end of the arc-shaped rod 11 is hinged to the sliding block 4, and the other end is slidably connected to the arc-shaped sleeve 13. When the arc-shaped sleeve 13 is in the positioning state, pressing the tweezer rod 1 causes the arc-shaped rod 11 to slide inside the arc-shaped sleeve 13, which guides the tweezer rod 1 so that the two electrode heads 2 can be precisely aligned, avoiding misalignment and affecting the use effect.

[0022] The driving mechanism includes a stud 12, a rotating cylinder 10, a connecting post 5, and a threaded groove 17. The end of the connecting post 5 is connected to the connecting seat 3. The rotating cylinder 10 is rotatably connected to the connecting post 5 to improve the stability of the rotation of the rotating cylinder 10. The threaded groove 17 is set inside the rotating cylinder 10, and the stud 12 is threadedly connected to the threaded groove 17. The end of the stud 12 is connected to the arc-shaped sleeve 13. Through the coordinated use of the rotating cylinder 10, the threaded groove 17, and the stud 12, the arc-shaped sleeve 13 can be easily raised and lowered, thereby adjusting the deformation of the spring 14 and changing the pinching force between the two tweezers 1.

[0023] The connecting column 5 is connected to a positioning mechanism for positioning the rotating cylinder 10. The positioning mechanism includes a guide column 6, a spring seat 7, a spring 8, a positioning plate 9, and multiple positioning protrusions 15. The guide column 6 guides the positioning plate 9, the spring seat 7 is fixed to the connecting column 5, the positioning plate 9 is slidably connected to the connecting column 5, the spring 8 drives the positioning plate 9 to move away from the spring seat 7, and the multiple positioning protrusions 15 are connected to the side of the positioning plate 9. When operating the rotating cylinder 10, pressure is applied to the positioning plate 9, causing it to move closer to the spring seat 7. The spring 8 is gradually compressed, and the positioning protrusions 15 separate from the positioning grooves 16, thus loosening the rotating cylinder 10 and facilitating its rotation. When the rotating cylinder 10 needs to be positioned, the positioning plate 9 can be directly released, and the compressed spring 8 drives the positioning plate 9 back to its original position, causing the positioning protrusions 15 to connect to the corresponding positioning grooves 16, thereby fixing the rotating cylinder 10 in place.

[0024] The end of the rotating cylinder 10 is provided with multiple positioning grooves 16, which match the positioning protrusions 15.

[0025] Spring 8 is fitted onto connecting post 5, and both ends of spring 8 are connected to positioning plate 9 and spring seat 7.

[0026] The end of the guide post 6 is fixed to the positioning plate 9, and the guide post 6 is slidably connected to the spring seat 7. The guide post 6 plays a good guiding role for the positioning plate 9, so that the positioning plate 9 can move back and forth steadily.

[0027] Working Principle: During use, spring 14 is compressed, providing a certain pinching force between the two tweezers 1, facilitating use by medical personnel. When the pinching force needs to be increased, the positioning plate 9 is pressed down, moving it closer to the spring seat 7. At this time, spring 8 is gradually compressed, and the positioning protrusion 15 separates from the positioning groove 16, loosening the rotating cylinder 10. Rotating the rotating cylinder 10 then drives the stud 12 downward, simultaneously moving the arc sleeve 13 and the two sliding blocks 4 downward. Spring 14 is compressed, increasing the pushing force on the two tweezers 1, thus increasing the pinching force between them. When the pinching force needs to be reduced, rotating the rotating cylinder 10 drives the stud 12 upward, simultaneously moving the arc sleeve 13 and the two sliding blocks 4 upward. Spring 14 gradually recovers, reducing the pushing force on the two tweezers 1, thus decreasing the pinching force between them. This allows for adjustment according to the usage habits of different medical personnel, making it highly adaptable. Once the pinching force between the two tweezers 1 is appropriate, the positioning plate 9 is released directly. The compressed spring 8 drives the positioning plate 9 back to its original position, so that the positioning protrusion 15 is connected to the corresponding positioning groove 16, thereby positioning the rotating cylinder 10, and then positioning the stud 12 and the arc sleeve 13, preventing the sliding block 4 from sliding and facilitating the operation of the dissecting instrument.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
