Problems solved by technology
[0007] The object of the present invention is to provide a kind of cataract core breaker, to solve the existing cataract core breaker on the market proposed by the above-mentioned background technology inconvenient to use Adjust its own length according to actual needs, and at the same time, after a long period of use, it is easy to slip between the nuclear crusher due to sweating of the user's hands, thereby reducing the practicality of the cataract nuclear crusher itself. nature, the overall nuclear crushing effect is poor, and the problem of incomplete nuclear crushing is prone to occur. Unnecessary injury to the patient and increased difficulty in the operation of the overall broken nucleus

The invention discloses a cataract nucleus breaker. The cataract nucleus breaker comprises a supporting frame, a handle, a vortex spring and a protective frame; a mounting shaft is fixedly mounted onthe side of the right end of the supporting frame; the handle is mounted on the right side of the mounting shaft; the protective frame is fixedly mounted on the outer side of the handle, and a slidingblock is mounted on the inner side of the end of the protective frame; a fixing cylinder is installed in the middle of the supporting frame; a lifting rod is installed in the fixing cylinder; an endsuction nozzle is installed at the left end of the fixing cylinder; a moving column is installed in the end suction nozzle; a limiting column is installed in a guide positioning rod; side clamping holes are formed in the side of the guide positioning rod; and an inserting block is mounted on the inner side of each side clamping hole. According to the cataract nucleus breaker, the length of the cataract nucleus breaker can be conveniently adjusted according to the actual use condition, and meanwhile, the possibility that the cataract nucleus breaker is loosened can be reduced, the overall nucleus breaking effect can be effectively improved, and repeated nucleus breaking operation is avoided.
Description
technical field [0001] The invention relates to the technical field related to cataract, in particular to a cataract core breaker. Background technique [0002] Cataract is a common disease that is more common in middle-aged and elderly people, and cataract refers to the change of optical quality caused by the decrease of transparency or color change of the lens. In order to reduce the troubles caused by cataract to the crowd, some people will use cataract surgery for treatment. In cataract surgery, in order to reduce the surgical incision and reduce the damage to the lens-like posterior capsule and corneal endothelial cells, it is usually necessary to use a small incision non-phacoemulsification operation, so when performing manual nuclear fragmentation for senile cataract, the nuclear fragmentation device is An indispensable tool. [0003] However, most cataract nucleators now have the following problems: [0004] 1. It is inconvenient to adjust the length of the existin...
