Problems solved by technology
[0003] However, at present, when the traditional crystal nucleus delivery device is in use, its internal triggering parts lack the safety protection function, and it is very easy to accidentally touch it when it is operated by hand, causing the clamping part to start at an inappropriate time, which is likely to cause secondary damage to the patient. Injury, affecting the postoperative recovery effect of patients

The invention provides a crystal nucleus delivery device for cataract surgery, and relates to the technical field of surgical instruments. The lower end of the hollow pipe is connected with the suction cup, the upper end of the hollow pipe is connected with the balloon, and the balloon is communicated with the suction cup through the hollow pipe. The sleeve is fixedly connected to the outer part of the hollow pipe, and the outer part of the sleeve is connected with a movable cylinder; the suction cup is connected with the clamping claw, and the clamping claw is connected with the movable cylinder through a connecting rod. An operator needs to inwards press the tops of the two movable hook pieces at the same time, so that the crystalline lens tightening and fixing effect can be achieved, when the top of a single movable hook piece is inwards pressed and stressed, the movable barrel cannot be triggered to move downwards, the safety effect is achieved, and operation is guaranteed. The problems that when the crystal nucleus delivery device is used, an internal trigger component lacks a safety protection function, mistaken touch is very likely to happen in the handheld operation process, and secondary injury is likely to be caused to a patient are solved.
Description
technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a lens nucleus ejector for cataract surgery. Background technique [0002] Cataract is one of the most common blinding eye diseases. The cornea and lens are the main refractive structures of the human eye. Under normal circumstances, the lens is transparent, and light passes through the lens and other refractive media to reach the retina, so that the outside world can be clearly seen. Objects, once the lens is clouded for some reason, it will affect the retinal imaging, making it difficult for people to see things, that is, the clouding of the lens leads to decreased vision and cataracts. Surgery is currently the only effective treatment for cataracts. Cataract surgery generally uses clear corneal microincision phacoemulsification to remove the cloudy lens. However, if the patient's corneal endothelial count is low, superhard nucleus, lens subluxation, or rupture o...
