Background

Cataracts are a common blinding eye disease. The human eye has a tissue called the lens, which is normally transparent, through which light passes and some refractive interstitium to reach the retina, in order to see clearly the outside objects. Once the lens becomes cloudy for some reason, it can affect the retinal image, making it unsightly. That is, cataract is a condition in which the vision is deteriorated due to clouding of the lens. In cataract surgery, it is necessary to "tear" a circular cuff in the anterior capsule to facilitate subsequent cataract extraction and intraocular lens implantation.

The existing capsulorhexis process is generally carried out by a doctor of a main knife according to working experience, and if the size of a capsulorhexis which is torn is too large, the fixation of the artificial lens can be influenced; the capsule opening is too small, which may influence the subsequent ultrasonic emulsification operation; deviation of the capsulorhexis may affect the neutrality of the intraocular lens, and thus the recovery of the patient's postoperative vision.

Detailed Description

In order to explain the technical content, structural features, achieved objects and functions of the present invention in detail, the following embodiments are described in detail with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the utility model discloses a capsulorhexis assistor, including supporting operating means 1 and the equipment 2 that uses, operating means 1 is equipped with the working chamber 12 that the axis was arranged including implanting a section of thick bamboo 11 in implanting a section of thick bamboo 11, is equipped with the push rod 13 that can axial motion in the working chamber 12, and equipment 2 locates in the working chamber 12 and can follow the motion of working chamber 12, and equipment 2 is including the elasticity cyclic annular 21 of locating push rod 13 one end.

As shown in fig. 2, the elastic ring-shaped member extends from the implantation tube to form a reference ring, and the doctor can tear the posterior capsule within the range of the ring-shaped member by directly referring to the ring-shaped member after adjusting the position. In the present application, the resilient ring may also be a dual rod structure with both ends in the implantation cylinder (as shown in fig. 3).

In other embodiments of the present application, the side of the elastic ring 21 facing the capsular sac is provided with a hydrophilic layer, the hydrophilic layer is adsorbed with a staining agent (typically trypan blue), the capsular sac can be left with a mark by contact staining during use, and the doctor can tear the sac against the mark after withdrawing the aid.

In yet other embodiments of the present application, as shown in fig. 4, a cavity 22 is formed in the elastic ring-shaped member 21, and a bellows 23 is formed in the cavity 22; one side surface of the elastic annular part 21 is provided with a plurality of dyeing ports 24 which are communicated with the cavity 22 and are uniformly spaced, and one end of each dyeing port 24 close to the cavity 22 is provided with a dyeing agent bag 25;

the dyeing agent bag 25 is fixedly connected with the inner wall of the dyeing port 24, and the end face of the dyeing agent bag 25, which is opposite to the telescopic air bag 23, exceeds the dyeing port 24; an axially arranged needle 26 is arranged in the dyeing port 24, the length of the needle 26 is smaller than that of the dyeing port 24, and the end of the needle 26 facing the dyeing agent bag 25 is shaped into a first needle point (upper end of the needle in the drawing).

The dyeing agent bag is made of medical silica gel, when one end of the dyeing agent bag, which faces the telescopic air bag, is extruded, one end of the dyeing agent bag, which is far away from the telescopic air bag, can deform and move along the dyeing port until the dyeing agent bag is punctured by a needle, and the dyeing agent in the dyeing agent bag can be extruded out. On the other hand, the needle can play a role in guiding a path of the coloring agent, and because the extruding direction and force of the coloring agent from the liquid outlet are not controllable, the needle can ensure that each coloring point is more uniform.

As shown in fig. 5, the side wall of the first pinpoint is provided with a plurality of fenders 27 arranged circumferentially, and the edge of the fender 27 facing the dye agent bag 25 is shaped into a blade. The top of the needle is provided with a cross wing plate to prevent the staining agent from going out due to too close contact point with the silica gel after the staining agent is penetrated through by the traditional needle as shown in figure 6.

As shown in fig. 7, an air inlet pipeline 14 and an air outlet pipeline 15 which are communicated with the telescopic air bag 23 are arranged in the push rod 13. The end of the air inlet pipeline 14 is connected with a squeezing bag 16, and the end of the air outlet pipeline 15 is connected with a valve 17. A one-way valve (not shown in the drawings) is provided between the bladder 16 and the inlet line 14.

In practical application, a one-way valve can be arranged between the squeezing bag and the air inlet pipeline, when the squeezing bag is flattened, air enters the telescopic air bag through the squeezing bag, the air cannot escape from the telescopic air bag under the condition that the valve is closed, and medical personnel can not pinch the squeezing bag all the time; when dyeing is finished, the pressure in the telescopic air bag can be automatically balanced with the atmospheric pressure when the valve is opened.

In still other embodiments of the present application, as shown in fig. 8, an end of the needle 26 away from the dye sac 25 is formed as a second needle tip, the needle 26 is disposed in the dye port 24 through a needle holder 28, a plurality of axially disposed slide grooves are disposed on an inner wall of the dye port 24, the needle holder 28 is capable of moving along the slide grooves, and a spring plate is disposed below the needle holder 28 in the slide grooves.

In this embodiment, the upper end of needle is used for pricking the dyeing agent bag and makes things convenient for the drainage, and along with the dyeing agent bag is continued the downward extrusion by flexible gasbag, the certain degree of depth of back cyst membrane can be pricked to the lower extreme of needle, is similar to the tattoo, plays better marking effect. An elastic sheet (not shown in the attached drawing) is arranged below the needle frame in the sliding groove, when no gas exists in the air bag, the needle is contained in the dyeing port under the action of the elastic sheet, and the damage to the sac membrane caused by the fact that the needle point extends out of the dyeing port before dyeing is prevented.

In summary, the preferred embodiments of the present invention are only examples, and the scope of the present invention is not limited thereto, and all equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the specification are within the scope covered by the present invention.
