Multifunctional Cataract Surgical Hook

Abstract

The invention discloses a multifunctional cataract surgical hook, and relates to ophthalmology medical apparatuses and instruments. The multifunctional cataract surgical hook is provided with an L-shaped hollow hook body, a connecting portion and a hollow handle. A downward-bending portion is arranged at the front end of the horizontal portion of the L-shaped hollow hook body. The end portion of the downward-bending portion is a globoid. The perpendicular portion of the L-shaped hollow hook body is a reversed cone. An upper water outlet hole and a lower water outlet hole are formed in the downward-bending portion above the globoid. The upper end portion of the reversed cone is connected with the connecting portion. The connecting portion is respectively connected with the hollow handle and a medical infusion tube. Due to the fact that the whole multifunctional cataract surgical hook is in a streamline type, smooth flowing of water flow is facilitated, and an incision and intraocular tissues are not easily damaged. The tail end of the horizontal portion of the hollow hook body is in a globoid shape, the two water outlet holes are formed close to the tail end, splashed water and eddies with no destructive power are generated by the collision of the two intraocular water flows, water outflowing is facilitated, water flows into anterior chambers inside eyeballs, the incision can be formed on purpose as the occasion requires for water leakage, a surgery can be more rapidly and safely completed, the anterior chambers are kept stable under the situation that the water leaks from the incision, and the surgery is safely completed.

Description

Technical field [0001] The invention relates to ophthalmic medical equipment, in particular to a multifunctional cataract surgical hook. Background technique [0002] In the existing ophthalmic cataract surgery, since incision leakage often occurs, it is easy to cause complications. [0003] The reduction of cataract incisions and the significant reduction of related complications are a highlight in the history of cataract surgery, and it is also the direction of ophthalmologists’ long-term efforts. In ophthalmic surgery, especially small incision cataract extraction, rational use of anterior chamber perfusion and Leakage of the incision can simplify the procedure and reduce the complications of the operation. Chinese patent CN201094694 discloses a perfusion squeezing nucleus scalpel for the treatment of cataracts. The handle is connected with a hollow nucleus slicing knife head. The end of the hollow nucleus slicing knife head is provided with a water outlet and a nucleus picking...
