[0024] Refer to Figures 1 - 3 , an embodiment provided by the present invention: An electrocoagulation head for ophthalmic surgery, including that a first special-shaped post 9 is slidably connected inside an outer shell 1, which is used to protect internal precision components and provide operating comfort. A plurality of second fixed posts 11 are fixedly connected to both the upper and lower ends of the outside of the first special-shaped post 9, which are used to stably fix a gear 12. An L-shaped plate 10 is fixedly connected to the outside of the second fixed post 11, and a gear 12 is rotatably connected to the outside of the L-shaped plate 10, which is used to mesh with a rack 13 and a tooth plate 8. Racks 13 are fixedly connected to both the upper and lower ends inside the outer shell 1, which are used for the sliding of the first special-shaped post 9. The outside of the rack 13 is meshed with the outside of the gear 12, and the outside of the gear 12 is meshed with the outside of the tooth plate 8, which is used for the sliding of a telescopic post 6. A fixed plate 2 is fixedly connected to the outside of the first special-shaped post 9, a first fixed post 5 is rotatably connected inside the fixed plate 2, and a clamping component is rotatably connected to the outside of the first fixed post 5 to adapt to different surgical requirements or the habits of operators. The clamping component includes a movable bar 3, and a limit post 4 is fixedly connected to the bottom of the movable bar 3, which is used to limit the telescopic post 6. A telescopic post 6 is slidably connected inside the first special-shaped post 9 to realize the length adjustment of the electrocoagulation head. A plurality of holes 7 are opened on the outside of the telescopic post 6, and the outside of the limit post 4 is engaged with the inside of the holes 7. A tooth plate 8 is fixedly connected to the inside of the telescopic post 6.
[0025] Such as Figure 1 , Figure 4As shown in the figure: Inside the telescopic column 6, a plurality of fixed blocks 14 are fixedly connected. On the adjacent side of the plurality of fixed blocks 14, a base 15 is fixedly connected. On the outside of the telescopic column 6, a special-shaped column two 17 is fixedly connected. Inside the special-shaped column two 17, a rotary cover 18 is threadedly connected. On the outside of the rotary cover 18, a groove 19 is provided. Inside the rotary cover 18, an electrocoagulation knife 20 is slidably connected. On the outside of the base 15, a gripper 16 is fixedly connected, which grips and fixes the electrocoagulation knife 20 to ensure precise operation during the operation.

[0027] Working principle: First, before use, press the movable bar 3 to drive the limit post 4 to rotate upward on the outside of the fixed column one 5, pull the telescopic column 6 outwards, and the toothed plate 8 fixed to the telescopic column 6 also moves outwards. As a result, the gear 12 meshing with the toothed plate 8 starts to rotate on the outside of the fixed column two 11 and is fixed to the special-shaped column one 9 by the L-shaped plate 10. At the same time, the gear 12 also meshes with the rack 13, causing the special-shaped column one 9 to be driven to move forward inside the housing 1. When adjusted to the appropriate length, lower the limit post 4 so that it is stuck in the hole 7 to limit the telescopic column 6. When replacing the electrocoagulation knife 20, rotate the rotary cover 18 with the groove 19 to move the rotary cover 18 outwards, so that the gripper 16 inside the special-shaped column two 17 is released without the force of contraction. Thus, the electrocoagulation knife 20 can be taken out for replacement. At the same time, the other end of the gripper 16 is firmly fixed to the inside of the telescopic column 6 by the fixed block 14 on the base 15.
