Description
Technical Field
The invention relates to the field of ophthalmic medical equipment, in particular to a device for removing epithelial cells of the equator of a crystalline lens.
Background
With the wide development of modern cataract ultrasonic emulsification technology and femtosecond laser assisted cataract surgery technology, the posterior cataract becomes an important factor affecting the postoperative vision of patients. It should be noted that the proliferation, migration, fibrosis of residual lens epithelial cells occurs to a varying degree in almost all lens capsule membranes after cataract extraction, and removal of residual lens epithelial cells has been a very focused research focus for cataract surgeons over the last decades. Various adverse events after cataract surgery, such as shrinkage of the capsular bag, dislocation after intraocular lens surgery, and the like, are all associated with proliferation, migration, fibrosis of residual lens epithelial cells. Although clinical doctors can remove lens epithelial cells as much as possible by adopting various methods, prevent posterior cataract and capsular bag shrinkage, such as improving operation skills, polishing anterior and posterior capsular bags, improving artificial lens design and materials, and the like, the posterior cataract and capsular bag shrinkage still have quite high incidence, especially in children patients, the incidence of posterior cataract still reaches up to 100%, and in patients with zonule laxity, such as ultra-high myopia and closed angle glaucoma patients, the incidence of capsular bag shrinkage after cataract operation is quite high, and various problems such as pupil locking, artificial lens deviation, myopia deviation and the like can be caused. In addition, it also limits the development of biomimetic refractive intraocular lenses. Therefore, in cataract surgery, it is of great clinical importance to remove as many lens epithelial cells as possible.
In the prior cataract surgery, after removing the lens nucleus and completing the lens cortex removal, the bag is filled with a viscoelastic agent, and a polisher stretches into the bag to scratch the inner surface of the bag so as to remove residual epithelial cells in the bag, including polishing of the anterior bag and the posterior bag, but the equatorial epithelial cells cannot be removed in the prior art. There are several general problems with existing polishing methods:
1. after the lens is removed, the lens capsule is soft and swaying, and doctors cannot operate the lens capsule well when polishing the capsule, so that the efficiency is generally low; 2. although filling and swelling of the capsule membrane can be ensured by injecting a large amount of viscoelastic agent into the capsule membrane in the polishing process, because the viscoelastic agent is sucked out after polishing, the operation steps and the operation time are increased, and complications such as ocular hypertension and the like are easily caused by incomplete suction of the viscoelastic agent; 3. the capsule membrane of the equatorial part of the lens is a germinal area of lens epithelial cells and is also the most dense part of epithelial cell residues, but the equatorial part of the lens is positioned behind the iris and cannot be observed in the operation, so that in the prior art, a doctor cannot polish the equatorial part; 4. under the operation of small pupils, polishing of the front and rear capsule membranes increases difficulty due to the reduction of the visible range, and even has serious risk of rupture of the capsule membranes; 5. in modern refractive cataract surgery, femtosecond laser is often used for assisting, accurate anterior capsular opening manufacturing is achieved, but in the femtosecond surgery, the cortex below can be cut off together when anterior capsular is cut, and because the incision is very neat, a doctor is required to attract the anterior capsular when the cortex is removed by negative pressure attraction, and traction on the zonules is increased.

The traditional capsule membrane polisher can only polish after crystal removal, a large amount of viscoelastic agent is needed, and the capsule membrane is soft and swaying, so that the polishing efficiency is low.
In addition, as shown in fig. 4, the front capsule membrane 8 and the lower cortex 7 are cut together when the capsule opening is made by using the femtosecond laser, the fracture is very clean (similar to two kinds of paper which are orderly stacked), and the negative pressure suction apparatus is difficult to ensure that the front capsule membrane is not pulled to the upper part when the lower cortex is pulled out; as shown in fig. 5, the edges of the anterior capsule membrane 8 and the cortex 7 at the capsule opening are dislocated by the traditional manual capsule tearing, and the negative pressure aspirator can conveniently grasp the part of the cortex edge beyond the rough surface of the anterior capsule membrane to remove the part in the subsequent operation step, so as to avoid directly attracting the anterior capsule membrane; as shown in figure 6, the polishing rod and the working rod are structured, so that the polishing device can be easily inserted between the front capsule and the leather, the end faces of the polishing rod and the working rod are separated to ensure that the leather and the front capsule are misplaced, and the negative pressure suction device can be pulled out of the leather below on the premise of not pulling the front capsule after having an acting point.
Example 2
Referring to fig. 7, this embodiment differs from embodiment 1 in that: the section of the polished rod 4 is zigzag.
Compared with embodiment 1, the zigzag structure is actually a plurality of spliced triangles, so that a plurality of edges on the top surface of the polishing rod form a plurality of edge surfaces, the polishing effect is better, and the polishing efficiency is further improved.
Example 3
Referring to fig. 8, this embodiment differs from embodiment 1 in that: the section of the polishing rod 4 is trapezoid, and the top surface of the polishing rod 4 is formed into a rough surface.
Compared with embodiment 1, the polishing rod has a flatter overall cross section and is matched with the rough surface formed on the upper surface, so that the polishing force is softer, and the probability of damaging the capsule is reduced.
Example 4
Referring to fig. 9, this embodiment differs from embodiment 1 in that: the section of the polishing rod 4 is arc-shaped, and the top surface of the polishing rod 4 is formed into a rough surface.
Compared with the embodiment 1, the polishing rod has smoother overall cross section, the top surface is formed into the cambered surface matched with the front capsule, the structure of the edge of the polishing rod is eliminated, and the probability of damage to the capsule is further reduced.
Example 5
Referring to fig. 10, this embodiment differs from embodiment 1 in that: the end of the working rod 3 or the polishing rod 4 is connected with an axially arranged extension rod 6, the extension rod 6 is made of flexible materials, the extension rod 6 can move on the horizontal plane along with the polishing rod 4, the extension rod 6 can be bent in the vertical plane direction, and the top surface of the extension rod 6 is formed into a rough surface.
The extension rod can also be manufactured by adopting an integrated molding process with the working rod or the polishing rod, and the whole extension rod is manufactured by adopting a medical polymer material.
As shown in fig. 11, in one embodiment, a flexible extension rod 6 is provided with a support rib 9, the support rib 9 is formed by a plurality of sections of short rods hinged with each other, and the short rods are hinged with each other through a horizontal shaft so that the short rods can only move in a direction perpendicular to a polishing surface; accordingly, as shown in fig. 11, the flexible extension rod wrapped outside the short rod can only deform in the vertical direction to fit the equatorial portion (up-and-down bending at the viewing angle shown in fig. 11) during polishing, and cannot bend in the horizontal direction to avoid uncontrollable deformation during polishing (up-and-down bending at the viewing angle shown in fig. 11).
In this example, a soft polishing material was attached to the tip of the polisher in comparison with example 1, so that the polishing could be performed deep into the equatorial region, and the epithelial cells attached to the equatorial region could be effectively removed.
