Description

A foldable intraocular foreign body storage device

technical field

The utility model relates to an ophthalmic surgical instrument, in particular to a foldable intraocular foreign matter storage device.

Background technique

Intraocular foreign bodies are common in open eye trauma, clinically divided into magnetic foreign bodies and non-magnetic foreign bodies according to whether they are magnetic or not. For magnetic foreign bodies, magnets or rare earth magnetic rods are often used to remove them; for non-magnetic foreign bodies, foreign body tweezers or foreign body graspers are often used to assist in removing them.

In the process of removing magnetic and non-magnetic intraocular foreign bodies, when withdrawing from the scleral (corneal) incision, the incision is often unsuitable and the foreign body is incarcerated, which easily damages the surrounding tissues, resulting in iatrogenic holes and continuous leakage of the incision, causing hypothermia. Intraocular pressure, choroidal detachment and other risks; and for some foreign bodies with irregular shape, weak magnetism or inconvenient to hold, the position is easy to wander, or even fall off twice and damage the retina, which increases the difficulty of surgery and prolongs the operation time. bring about unforeseen consequences.

Clinically, there is still a lack of a device that is safe and suitable for removing most intraocular foreign bodies.

Utility model content

The technical problem to be solved by the utility model is to provide a foldable intraocular foreign body storage device.

For solving the problems of the technologies described above, the technical solution of the utility model is:

A foldable intraocular foreign body storage device, comprising a sleeve, a handle bracket and a storage bag, the sleeve is a hollow cylindrical structure, a storage bag is fixed at one end of the handle bracket, the storage bag is a foldable structure, the The main structure of the handle bracket is arranged inside the sleeve and can slide forward and backward along the sleeve, and the storage bag is inserted into the inside of the sleeve when it is folded.

Preferably, in the above-mentioned collapsible intraocular foreign body storage device, the material of the sleeve is plastic.

Preferably, in the above-mentioned foldable intraocular foreign body storage device, when the storage bag is unfolded, the pocket is an annular elastic steel ring, and a conical storage body is fixedly connected to the bottom of the pocket, and the storage body is made of polymer nanomaterials.

Preferably, in the above-mentioned collapsible intraocular foreign body storage device, a chute is provided on the side of the sleeve away from the storage bag, and a handle protrusion is provided on the end of the handle bracket away from the storage bag, and the handle protrusion is embedded in the chute , move back and forth along the chute.

The structure of the utility model has the following beneficial effects:

The above-mentioned foldable intraocular foreign body storage device has an ingenious structural design. By adopting a foldable storage bag design, the 23G cannula is used to insert into the eye, and the foreign body is placed in the storage bag to be taken out, avoiding secondary detachment of the foreign body and damaging the retina, and simplifying the operation. Steps to reduce surgical complications have very important clinical significance.

Detailed ways

For further illustrating the utility model, now cooperate with accompanying drawing to elaborate:

As shown in Figure 1-2, the foldable intraocular foreign body storage device includes a plastic sleeve 1, a handle bracket 3 and a storage bag 5. The sleeve is a hollow cylindrical structure with an inner diameter of 0.5 mm and an outer diameter of 0.5 mm. The diameter is 0.6mm, which can be conveniently cut through the 23G vitreous body. A storage bag is fixed at one end of the handle bracket. The storage bag is a foldable structure. The main structure of the handle bracket is arranged inside the sleeve and can be The casing slides back and forth, specifically, the side of the casing away from the storage bag is provided with a chute 2, the end of the handle bracket away from the storage bag is provided with a handle protrusion 4, and the handle protrusion is embedded in the chute , move back and forth along the chute, when the storage bag is unfolded, the mouth of the pocket is an annular elastic steel ring, and the bottom of the pocket is fixedly connected with a conical storage body with a depth of 15mm when unfolded, and the storage body is made of polymer nanomaterials. When the storage bag is in a folded state, it is inserted into the inside of the sleeve, and the storage bag is stored through the sleeve.

During use, the foldable intraocular foreign body storage device enters the eye and unfolds the storage bag, and the intraocular foreign body is stored in the storage bag and taken out, and the foreign body is firmly located in the storage bag to avoid secondary falling off.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
