[0018] A method for using a bipolar electrocoagulation device for ophthalmic surgery comprises the following steps:

[0019] S1. First, pull the limit plate outward to move the opening away from the mounting seat, then lift the pliers body upward to remove it from the top cover before use.

[0020] S2. When the angle between the adjusting handle and the connecting handle needs to be adjusted, the adjusting handle is turned on the rotating seat. After the adjustment is completed, the L-shaped sliding block fixes the adjusting handle under the action of the second spring;

[0021] S3. When the tweezer tip needs to be replaced, remove the connecting seat from one end of the adjustment handle and then replace the tweezer tip with an appropriate one;

[0022] S4. When the distance between the two tweezer tips needs to be adjusted, the nut ring is rotated to move the nut ring on the screw, thereby adjusting the distance between the two tweezer tips;

[0023] S5. After use, insert the adjusting handle into the corresponding limiting hole and press downward. During the pressing process, one side of the connecting handle contacts the top cover and moves downward to seal the connecting box. At the same time, it drives the two surgical towels to clamp the adjusting handle and the tweezers tip, and drives the first through hole to correspond to the connecting tube. At this time, the external high-temperature steam enters the connecting box through the connecting tube to disinfect the tweezers tip. At the same time, pull the limiting plate to make the opening contact the mounting seat, and push the limiting plate to drive the insert into the socket to limit the mounting seat.

[0024] In the present application, first, the limit plate is pulled outward and flipped upward to move the opening away from the mounting seat and the insert strip out of the socket, and then the pliers body is pulled upward to remove the pliers body from the top cover. At this time, the top cover can be reset upward under the action of the fourth spring and drive the wedge block away from the clamping plate. The two clamping plates can be reset and moved under the action of the third spring. At the same time, the blocking plate can be reset under the action of the fifth spring, so that the first through hole and the connecting pipe are misaligned, and then the clamp can be used;

[0025] When the angle between the adjusting handle and the connecting handle needs to be adjusted, the adjusting handle is pulled and rotated on the rotating seat. After the adjustment is completed, the L-shaped sliding block fixes the adjusting handle under the action of the second spring.

[0026] When the tweezer tip needs to be replaced, press the buckle inward and then pull the connector outward to remove the connector from one end of the adjustment handle. Then replace the appropriate tweezer tip so that the conductive column contacts the conductive cylinder. At this time, the tweezer tip is energized.

[0027] When the distance between the two tweezer tips needs to be adjusted, the nut ring is rotated to move the nut ring on the screw rod, thereby adjusting the distance between the two tweezer tips;

[0028] After use, insert the adjusting handle into the corresponding limiting hole and press downward. During the pressing process, one side of the connecting handle contacts the top cover and moves downward to seal the connecting box. During the downward movement of the top cover, the two sets of wedges can be used to drive the two splints closer to each other, drive the two surgical towels to clamp the adjusting handle and the tweezers tip, and drive the blocking plate downward through the extension block to make the first through-hole correspond to the connecting tube. At this time, the external high-temperature steam enters the connecting box through the connecting tube to disinfect the tweezers tip. Since the diameter of the adjusting handle is larger than the tweezers tip, the high-temperature steam can contact the tweezers tip. At the same time, the limiting plate is pulled to make the opening contact the mounting seat, and the limiting plate is pushed to drive the insert into the socket to limit the mounting seat, which can fix the pliers body in the connecting box. Beneficial Effects

[0029] In the present invention, for the bipolar electrocoagulation device for ophthalmic surgery, the forceps tips are fixed on the connecting seat, and the connecting seat is detachably connected to the adjusting handle, making it convenient to replace different types of forceps tips. Moreover, the angle between the adjusting handle and the connecting handle can be adjusted, effectively and reasonably increasing the surgical space and making the operation more convenient.

[0030] In the present invention, for the bipolar electrocoagulation device for ophthalmic surgery, by providing a connection box on one side of the main unit, not only can the pliers body be placed, but also two surgical towels can be driven to wrap the forceps tips during the placement process, effectively protecting the forceps tips. In addition, the pliers body can be fixed in the connection box by the limiting plate, preventing it from shaking during movement and enabling the intuitive discovery of the equipment situation of the pliers body.

[0031] In the present invention, for the bipolar electrocoagulation device for ophthalmic surgery, by providing connecting pipes on both sides of the connection box, during the placement process, high-temperature steam can enter the connection box to disinfect the forceps tips, eliminating the need for manual disinfection and making it more convenient to use.

[0032] In the present invention, for the bipolar electrocoagulation device for ophthalmic surgery, by providing a screw between the two connecting handles, and the nut ring on the screw abuts against one of the connecting handles, the distance between the two connecting handles can be adjusted, thus facilitating the adjustment of the maximum distance between the two forceps tips. Moreover, a first spring is sleeved on the screw, providing power for the reset of the connecting handle and preventing the elastic failure of the connecting handle.

[0033] In the present invention, by detachably setting the forceps tips on the adjusting handle and enabling the angle between the adjusting handle and the connecting handle to be adjusted, the flexibility of use can be improved. After use, the pliers body can be placed on the connection box, and during the placement process, the forceps tips can be wrapped and protected by two surgical towels. In addition, high-temperature steam can enter the connection box to disinfect the forceps tips, making it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
