Description

Cataract surgery is with tearing bag and incision mark device

Technical Field

The utility model belongs to a surgical instrument in the medical field, in particular to an auxiliary device which is used in cataract surgery of ophthalmology and assists in completing standardized capsulorhexis and incision preparation.

Background

The conventional phacoemulsification operation has a long learning curve due to high operation difficulty, precise operation and high technical requirement, and capsulorhexis and incision making in the phacoemulsification operation are the most important operation steps in the initial stage of the operation and are directly related to the subsequent operation of the phacoemulsification operation. At present, the cataract surgery requires standard operation, namely, the position of a capsulorhexis opening is required to be centered and is required to be in a standard circle shape, the size of the capsulorhexis opening is 5.0mm-5.5mm, the size of a main incision is 2.2mm-3.0mm, the size of an auxiliary incision is 1.5mm, and an angle of 90 degrees to 120 degrees is formed between the auxiliary incision and the main incision. The size difference of the pupils in the operation is large due to individual difference of patients, and a beginner is difficult to determine the diameter of the capsule tearing opening according to the size of the pupils, so that complications such as too large or too small capsule tearing, capsule membrane cracking and the like are easy to occur, and certain difficulty is brought to subsequent operation; and simultaneously, the position and the size of the surgical incision are marked.

Disclosure of Invention

The utility model aims to provide a cataract operation is with tearing bag and incision mark device, the invention is when using, covers the device on the cornea surface, confirms to place the position according to the cornea border, tears a mouthful size according to inner ring size control, confirms main incision position and supplementary incision position according to the rotation device of operator's custom. The problems existing in the background technology are solved: the size difference of the pupils in the operation is large due to individual difference of patients, and a beginner is difficult to determine the diameter of a capsule tearing opening according to the size of the pupils, so that the problems of too large or too small capsule tearing, capsule membrane cracking and the like are easy to occur; and simultaneously, the position and the size of the surgical incision are marked. The operation of an operator is more standard and accurate, and the operation quality and success rate are improved; meanwhile, the device can also be used for animal experiment operation. The invention has simple structure, convenient use, good stability and high reliability.

The technical scheme adopted for realizing the purpose of the invention is as follows:

a cataract surgery tears the bag and cuts the marking device, characterized by that the whole is the integrally formed silica gel material, the inner ring links with outer ring through the joint part; when the device is used, the device is covered on the surface of the cornea, and the placement position of the outer ring is determined according to the boundary of the cornea, so that the position of the device is centered; the position of the capsulorhexis opening marked by the inner ring is centered and is in a standard circular shape, and the size is set to be 6mm in order to avoid influencing observation in the operation; controlling the size of a bag tearing opening according to the size of the inner ring; the main incision position and the auxiliary incision position are determined according to the habit of an operator to the rotating device.

The outer ring has an outer diameter of 10mm or 11mm and a width of 0.5 mm; is a silica gel material.

The inner diameter of the inner ring is 6mm, and the width of the inner ring is 0.5 mm; is a silica gel material.

The inner ring and the outer ring are of concentric circular structures and are connected through a connecting part, and the width of the connecting part is 0.5 mm; at least three connecting parts are provided to stabilize the shape of the inner ring; is a silica gel material.

The length of the main incision mark is 2.2mm, 2.8mm and 3.0mm, and the height is 2 mm; is a silica gel material.

The auxiliary incision marks are positioned on two sides of the main incision mark and form an included angle of 90 degrees or 120 degrees with the main incision mark, the length of the auxiliary incision mark is 1.5mm, and the height of the auxiliary incision mark is 2 mm; is a silica gel material.

Fig. 2 is a schematic structural view of a cataract anterior capsulotomy guide device in the prior art. As shown in fig. 2, the authorization notice number isCN104812341AThe structure of the anterior capsulotomy guide device for cataract described in (1) includes an incision part 12 formed on one side of a body 10 constituting the anterior capsulotomy guide device. In operation, the surgeon first secures the body 10 to an additional insertion instrument. The insertion instrument may be formed in a hollow shape inside so that the elastically deformable body 10 is located inside thereof in an elastically deformable manner. In this state, before insertion through the corneal incisionCapsulotomy guide device 1. In this process, the body 10 is elastically restored after being released from the insertion instrument 20, thereby restoring to the original circular shape. The body 10 maintains a circular shape when it is inserted into the corneal incision and restored to its original state. When the guiding device 1 maintains a circular shape, the probability of obtaining an excellent surgical result will be increased. Also, after the front pouch is cut, an additional tool can be hung on the hanging groove 14 to remove the main body 10, so that the main body 10 can be easily removed.

The current anterior capsulotomy guide device has the following defects: because the device needs to enter the eye through the corneal incision for operation, the risk of damaging the structures such as the corneal endothelium, the angle and the like can be increased; moreover, the increase of the operation steps can obviously prolong the operation time and increase the risk of endophthalmitis; if the device is accidentally dropped into the eye, the dropping to form foreign matter can cause secondary damage to the tissues in the eye, which affects prognosis; on the other hand, even if the device is not detached, it may cause incision damage when passing through the corneal incision, possibly affecting the incision closure, leading to water leakage from the incision and increasing the risk of endophthalmitis.

Compared with the prior art, the invention has the beneficial effects that:

the invention uses the guide device in the shape of the concentric ring which is integrally formed to carry out the cataract surgery, therefore, the anterior capsule can be cut and the corneal incision can be made with the correct size, shape and position when the cataract surgery is carried out, thereby improving the effect of the cataract surgery.
