Description

Front bag polisher

Technical Field

The invention belongs to the field of ophthalmic equipment, and particularly relates to a front capsule polisher.

Background

In the cataract operation process, after the emulsified diseased crystalline lens and cortex in the crystalline lens capsular bag are absorbed, partial crystalline lens epithelial tissue still remains on the inner wall of the anterior capsule of the crystalline lens, if the diseased crystalline lens and cortex are not thoroughly cleared, after the artificial crystalline lens is implanted, the residual crystalline lens epithelial tissue can continue to grow and spread towards the posterior capsule along the inner wall of the anterior capsule in the recovery stage of the later operation period, finally the light transmittance of the posterior capsule of the crystalline lens is influenced, and the postoperative posterior cataract is caused. To prevent such posterior capsule failure, the lens epithelial tissue remaining on the inner wall of the anterior lens capsule and on the equator is polished. Chinese patent CN208942550U discloses a lens front capsule polisher, which comprises a handle, a connecting portion, a first operating portion and a second operating portion, wherein the connecting portion is a right angle, the first operating portion includes a first free end and a first fixed end, the second operating portion includes a second free end and a second fixed end, one end of the connecting portion is connected to the handle, the other end of the connecting portion is connected to the first fixed end and the second fixed end, and an obtuse angle is formed between the first operating portion and the second operating portion. The polisher enters the anterior chamber from the main incision and removes 360 degrees of lens cells under the anterior capsule of the lens through the swinging of the upper and lower operation ends and the scraping under the anterior capsule in one time. When the front bag polisher is used for polishing, the operation part swings, the polishing range is not easy to control, and the safety is poor.

Detailed Description

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the invention may be more readily understood by those skilled in the art. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 to 2, the present embodiment provides a front capsule polisher, which includes a polishing member 1, a housing 2, a motor 3, a cam 4, and a driving member 5. The housing 2 has a proximal end for the operator to hold and an opposite distal end closer to the patient's eye. The polishing element 1 protrudes from the distal end of the housing 2 and is bent to form an operating portion, which is in the form of an elongated needle, and the motor 3, the cam 4 and the driving element 5 are disposed in the housing 2. Specifically, the housing 2 includes a front housing 21 at a distal end and a rear housing 22 at a proximal end, the motor 3 is fixedly disposed in the rear housing 22, the cam 4 and the driving member 5 are movably disposed in the front housing 21, a through hole for the polishing element 1 to pass through is formed in the front housing 21, and the diameter of the through hole is larger than the diameter of the polishing element 1, so as to allow the polishing element 1 to vibrate up and down or left and right relative to the housing 2. The front case 21 and the rear case 22 are fixedly connected by screws or the like. The rear shell 22 is elongated for easy gripping by a human hand.

The output shaft of the motor 3 extends in a direction from the proximal end to the distal end of the housing 2. The cam 4 is coaxially arranged on the output shaft of the motor 3 and can rotate along with the output shaft of the motor 3 and is driven by the motor 3 to rotate. The cam 4 is movably connected with the driving member 5, a guide member 6 extending along a straight line is arranged in the housing 2 and used for guiding the motion track of the driving member 5, and the driving member 5 is movably connected with the guide member 6, so that the driving member 5 reciprocates along the guide member 6. The proximal end of the polishing element 1 passes through the housing 2 and is connected to the driving element 5 so as to be capable of linear reciprocating motion, thereby achieving the effect of removing residual lens epithelial tissue on the inner wall of the anterior lens capsule. The path of movement of the polishing element 1 depends on the direction of extension of the guide 6, and in other embodiments, the guide 6 may extend non-linearly, for example, may extend along a curve, so that the polishing element 1 may reciprocate non-linearly.
