Description

lens cortex dissector

technical field

The utility model relates to the technical field of medical equipment, in particular to a lens cortex dissociator.

Background technique

At present, during cataract surgery, there are many nuclei or cortex that are difficult to be suctioned under the corneal incision or hidden under the iris. The existing phacoemulsification handpiece cannot be completely sucked out. At the same time, when the capsule ruptures after cataract surgery, it cannot be used. The phacoemulsification handle sucks out the residual nucleus or skin. Finally, the existing emulsification handle has no lighting function, so there will be visual blind spots during the operation, resulting in incomplete suction of the nucleus and cortex.

Detailed ways

The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

Please refer to Figures 1 to 2, a lens cortex dissociator, comprising a handle 1, a connecting rod 2, and a paddle 3; the handle 1 is a cylindrical structure, and the connecting rod 2 is a stainless steel round rod, The connecting rod 2 is composed of a rear straight rod 201 and a front triangular rod 202, the straight rod 201 and the triangular rod 202 are integral structures, and the included angle between the two axes is an acute angle; The handle 1 is connected by threads, and the axes of the two are coincident; one end of the triangular rod 202 away from the straight rod 201 is provided with a paddle 3 by welding. The top view profile of the paddle 3 is oval, and the paddle 3 3 The thickness is largest at the center and decreases gradually from the center to the periphery.

Preferably, the length L1 of the handle 1 is 75mm.

The axis of the handle 1, the axis of the triangular rod 202 and the center line of the paddle 3 are coplanar.

Preferably, the included angle between the center line of the paddle 3 and the axis of the handle 1 is 90°.
