Embodiment Construction

[0011] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0012] The composition of the multi-purpose hook for phacoemulsification and intraocular lens implantation surgery includes an approximately "L"-shaped hook body 1 with approximately reverse "S"-shaped hook teeth 2 at the front end of the hook body. There is a handle 3 at the rear end of the hook body. The angle a at the joint between the approximately reverse "S" shaped hook teeth and the hook body is 45°-70°. The ends of the hook teeth are rounded.

[0013] The composition of the second specific embodiment of the present invention includes all the content of the above-mentioned embodiment, and the difference is that the angle a between the connection between the approximately reverse "S"-shaped hook teeth and the hook body is 45°.

Abstract

The invention provides a multi-purpose hook used in the extraction of cataract by phacoemulsification and embedding of artificial crystal, which comprises a hook body similar in L shape and hook teeth similar in reversed S shape at front end of the hook body. The invention, with the similar reversed S shaped hook teeth and the included angle of the hook teeth and the connecting place of the hook body is 45 degree to 70 degree, can serve as the pin chopping hook directly with good effect and can increase the speed for chopping the pit; besides, the hook teeth above mentioned can serve as the crystal position adjusting hook directly and can preciously and conveniently adjust the position through the rational chose included angle between the hook teeth and the hook body. Then invention integrates the pit chopping hook and the crystal position adjusting hook, not only lowers the cost, but also avoids the troublesome caused by frequently exchanging the instruments during operation, which is beneficial for lowering operation difficulty and accelerating the operation.

Description

(1) Technical field [0001] The invention relates to a surgical instrument, in particular to a special instrument for phacoemulsification cataract suction and intraocular lens implantation. (2) Background technology [0002] Phacoemulsification cataract extraction and intraocular lens implantation surgery is an effective and safe surgical method for cataract treatment. It has the advantages of no anesthesia, small incision, short time, quick recovery of vision, and no pain. In the implementation of phacoemulsification and intraocular lens implantation, various surgical instruments such as chopping hooks and lens adjustment hooks are needed. At present, there are many researches on the hacking hook. For example, the patent application number is 200520072061.5, which is called cataract superemulsion multi-blade splitting hook; 200520072062. . These technical schemes make the nuclear splitting operation more and more simple, and the safety performance is more and more higher. ...
