[0001] The utility model relates to the technical field of blade holders for ophthalmic surgery, in particular to a blade holder for ophthalmic surgery. Background Art
[0002] Ophthalmic surgery is a type of surgery specifically performed for ophthalmic diseases. Ophthalmic surgery requires a very high level of precision and is divided into primary, secondary, tertiary, and quaternary surgeries. Primary surgery is relatively simple, with low technical difficulty and low risk; secondary surgery is a medium-level surgery with medium risk and average technical difficulty; tertiary and quaternary surgeries have high risks, high technical difficulty, and complex surgical procedures. Therefore, a blade clamp for ophthalmic surgery has emerged. However, some existing blade clamps for ophthalmic surgery cannot limit the blade when clamping it, which may cause the blade to slide slightly during use, and thus cause damage to the patient's eyes. Therefore, a person skilled in the art provides a blade clamp for ophthalmic surgery to solve the problems raised in the above background technology. Utility Model Content

[0007] Compared with the prior art, the beneficial effects of the utility model are:
[0008] 1. First, place one end of the blade inside the blade placement groove, and then rotate the fixed threaded rod. The fixed threaded rod will drive the blade limit plate to move along the blade limit plate slide groove to one side of the blade until the blade limit plate completely rests against the blade. At this time, not only the blade is fixed inside the blade placement groove, but the blade limit plate can also limit the blade, thereby avoiding the situation in which the blade is not limited and slightly slides during the subsequent use of the blade, causing damage to the patient's eyes, thereby improving the safety of the device, and then the movable round rod is moved along the movable round rod slide groove to the side away from the blade clamp body, and then the movable round rod will drive the inner clamping plate to move to the side away from the inner connecting rod, and then the inner connecting rod is pulled to the side away from the blade clamp body through the inner connecting rod connector. The inner connecting rod will move to the side away from the blade clamp body under the action of the inner connecting rod slide rod and the inner connecting rod slide groove, and then the inner connecting rod will drive the lower clamping frame and the upper clamping frame to move to the inside of the blade clamp body, and then the lower clamping frame and the upper clamping frame will be on the rotating shaft. The upper surface of the blade will gradually close under the action of the retractable lower rod, and then the upper surface of the blade will contact and squeeze the retractable lower rod. At this time, the retractable lower rod will move upward and squeeze the first retractable spring. At the same time, the first retractable spring will also squeeze the retractable lower rod downward. When the lower clamping frame and the upper clamping frame are in a closed state, the retractable lower rod will squeeze the blade downward under the action of the first retractable spring, thereby further fixing the blade, thereby further improving the stability of the blade during use. Then the movable round rod is released, and then the inner clamping plate will move to one side of the inner connecting rod under the action of the second retractable spring until it completely rests against the inner connecting rod. At this time, the preparation work of the blade clamp body is completed, and then the blade clamp body can be picked up and worked through the operable area. When it is necessary to adjust the extended length of the blade, just repeat the above operation. The device can limit the blade through the blade limiting plate, thereby avoiding the situation in which the blade is not limited and slightly slides during the subsequent use of the blade, thereby causing damage to the patient's eyes, thereby improving the safety of the device.
[0009] 2. The device can adjust the extension length of the blade by pulling the movable round rod and the inner connecting rod connector, so that the user can perform ophthalmic surgery better and thus improve the surgical effect. BRIEF DESCRIPTION OF THE DRAWINGS
