Problems solved by technology

[0002] The existing technology is to use capsulorhexis forceps or capsulotomy needle to manually control the tearing or cutting of the precapsule to obtain a round shape. Without superb technology, it often fails.
There are also some inventions that cannot produce a round shape with smooth edges, causing the operation to fail

Embodiment Construction

[0017] Fix the bag cutter, install the handle, and retreat the bag cutter to the innermost side, leaving only the knife head outside the tube, such as ( figure 2 Exterior, Figure 4 section). Make a corneal incision, enter the selected position from the incision, the knife head penetrates the capsule, the control box or the hand rotates the inner core of the transmission flexible shaft, and drives it into the handle, the push rod pushes the capsule knife out of the tube, and the capsule knife returns to its original shape ( image 3 Exterior, Figure 5 Cross-section), the knife head draws or cuts the capsule membrane according to a circular arc, forming a smooth circle. Reverse rotation, the push rod pulls back the pouch cutter, and the head of the pouch cutter is transformed into a straight rod and returned to the pipe. Withdraw from the corneal incision and proceed to the next step of the surgery.

Abstract

The invention relates to an apparatus for automatically gashing crystalline lens anterior capsule membrane into a circle with a diameter as required during the implementation of cataract operation. The apparatus comprises a power control box capable of being connected with a soft shaft, a handle, and a vesicle gashing cutter made of memory metal. The inner part of the handle comprises the soft shaft, an internal core, and a transmission rod with a clamping device. The vesicle gashing cutter is straight when pulled back to the tube, and restored to be circular based on memory shape when pushedout of the tube; and the anterior capsule membrane is cut or sheared by the cutter head along the arc line so as to form smoothly circular shape with corresponding diameter. The vesicle gashing cutteris simply structured and convenient to be operated, can get into the atria easily and automatically, thereby improving the success ratio of operation and reducing the operation difficulty.

Description

technical field [0001] The invention is an instrument for automatically cutting and cutting the anterior lens capsule into a circular shape with a required diameter during ophthalmic cataract surgery. technical background [0002] The existing technology is to use capsulorhexis forceps or a capsulotomy needle to manually control the tearing or cutting of the precapsule to obtain a circular shape. Without superb technology, it often fails. There are also some inventions that cannot obtain a smooth-edged circle, causing the operation to fail. Or the capsulorhexis instrument is simply not easy to get in and out of the anterior chamber. Contents of the invention [0003] The present invention overcomes the deficiencies in the prior art. According to the current operation mode, a very small opening is cut on the cornea and it can be inserted into the head of the capsulorhexis device, and the capsule cutting knife is automatically pushed out from the tube. On the anterior caps...
