Description

Packaging structure for intraocular lens Technical Field The utility model relates to the technical field of intraocular lenses, in particular to a packaging structure for an intraocular lens. Background Intraocular lenses are typically made of synthetic polyacrylate materials that have good biocompatibility and optical properties for implantation into the human eye to restore or improve the vision of the patient. Preservation of intraocular lenses is an important link to ensure that they function properly when implanted in the eye, and should be stored in a light-resistant, sterile environment while avoiding severe shock or temperature changes during preservation. Currently, intraocular lenses are typically kept in penicillin bottles containing 0.9% sodium chloride solution. However, this packaging method has the problems that the intraocular lens is light, thin and soft, can sink to the bottom of the bottle in the solution, and the penicillin bottle mouth is small, so that the difficulty in clamping during the operation is high, and the intraocular lens can be damaged. Secondly, the intraocular lens cannot be stably suspended in 0.9% sodium chloride solution under the buoyancy effect, and storage and transportation stability are affected. Disclosure of utility model The utility model provides a packaging structure for an intraocular lens, which aims to solve the problems that the intraocular lens is sunk into the bottle bottom and is not easy to take out in the prior art, and can be taken out from the packaging conveniently while fixing the position of the intraocular lens. In order to solve the technical problems, the utility model adopts the following technical scheme: a packaging structure for an intraocular lens comprising a bottle; A bottle cap detachably connected with the bottle body, and The crystal support is detachably connected with the bottle cap and is suspended in the bottle body under the connection state of the bottle cap and the bottle body, wherein the crystal support comprises: one end of the connecting part is detachably connected with the bottle cap, A clamping portion connected with the other end of the connecting portion and used for clamping the intraocular lens, and the clamping portion includes: a clip groove for accommodating the intraocular lens, and And the clamping hooks are arranged at two sides of the clamping groove and are used for limiting the intraocular lens in the clamping part. In the scheme, when the intraocular lens is packaged, the intraocular lens is placed in the clamping groove, the clamping hook is used for limiting the displacement of the intraocular lens in the axial direction of the clamping groove, so that the intraocular lens is prevented from being separated from the lens holder, and then the bottle cap is connected with the bottle body, so that the packaging of the intraocular lens can be completed. Preferably, the maximum distance between the two hooks is equal to the body diameter of the intraocular lens. Preferably, the maximum vertical distance between the bottom of the clamping groove and the clamping hook is smaller than the riding height of the intraocular lens and larger than the vertical distance between the section of the intraocular lens and the end face of the optical body of the intraocular lens. Preferably, the surface shape of the clamping groove is matched with the surface shape of the support part of the intraocular lens. Preferably, the clamping part further comprises a through hole, the through hole is communicated with the clamping groove along the axial direction of the clamping groove, and the diameter of the through hole is smaller than that of the intraocular lens optical main body. Preferably, the clamping part further comprises a clamping opening, and the clamping opening is communicated with the clamping groove along the radial direction of the clamping groove. Preferably, a connecting piece is arranged in the bottle cap, and the connecting piece is detachably connected with the connecting part. Preferably, the total length range of the crystal support is 2/3 to 5/6 of the total length of the bottle body. The scheme of the utility model has the beneficial effects that: 1. The intraocular lens is secured within the packaging structure without damage and ensures stable storage of the intraocular lens in the preservation solution. 2. When the intraocular lens is stored or used, the intraocular lens can be conveniently accessed from the packaging structure under the premise of avoiding damage to the intraocular lens.
