Description

A corneal flap lifter with flushing head

technical field

The utility model belongs to the technical field of medical devices and relates to a corneal flap lifter, in particular to a corneal flap lifter with a flushing head.

Background technique

In the process of corneal laser surgery, the corneal flap needs to be opened first by the corneal flap lifter, the laser is applied successively to reset the corneal flap, and then the reset corneal flap is rinsed with irrigation fluid to wash away the debris that occurred during the operation.

However, the existing corneal flap lifter only has the corneal flap lifting needle, and can only realize the opening of the corneal flap. After the corneal flap is reset, the irrigator must be replaced to rinse the reset corneal flap. Since different instruments need to be replaced during the operation, it makes the operation of medical personnel very inconvenient. Simultaneously, owing to will carry out the replacement of instrument, therefore, it will prolong the time of operation inevitably, thereby has reduced the efficiency of operation, has increased patient's misery.

Therefore, there is an urgent need for a novel corneal flap lifter.

Contents of the invention

The purpose of this utility model is to provide a corneal flap lifter with a flushing head for the deficiencies of the above-mentioned prior art. There is no need to replace instruments during the process, which not only facilitates the operation of the medical staff, but also improves the efficiency of the operation, reduces the operation time and the pain of the patient.

In order to achieve the above object, the utility model provides the following technical solutions: a corneal flap lifter with a flushing head, which includes a hollow body, one end of the hollow body is provided with a corneal flap lifter needle, characterized in that the The other end of the hollow body is provided with a flushing needle, the diameter of the flushing needle is larger than the diameter of the corneal flap opening needle and the front end of the flushing needle is provided with a plurality of flushing holes, the plurality of flushing holes along the Different radial directions and different axial directions of the washing needles are arranged, and a connection head is arranged in the middle of the hollow body, and the connecting head is connected with a washing liquid storage bottle to provide washing liquid to the washing needles.

Further, wherein, the hollow body is made of metal.

Furthermore, wherein, the flap lifting needle and the flushing needle are made of silver.

The corneal flap lifter with flushing head of the utility model does not need to replace the instrument when the corneal flap is lifted and reset, which greatly facilitates the operation of the medical staff; at the same time, since there is no need to replace the instrument, Therefore, the operation time is reduced, the efficiency of the operation is improved, and the pain of the patient is reduced; moreover, the flushing hole of the flushing needle can spray flushing solution toward multiple different directions, rather than flushing toward a single direction liquid, therefore, its flushing efficiency is higher and the flushing effect is better.

Description of drawings

Fig. 1 is a schematic diagram of a corneal flap lifter with a flushing head of the present invention.

Detailed ways

The specific implementation of the present utility model will be described in detail below in conjunction with the accompanying drawings, and the content of the specific implementation is not a limitation to the protection content of the present utility model.

The utility model relates to a corneal flap lifter with a flushing head, the lifter can complete the functions of lifting the flap and rinsing and resetting the corneal flap with only one device, and does not need to replace the device during the operation, which not only facilitates the medical staff operation, and improve the operation efficiency, reduce operation time and pain of patients.

Fig. 1 shows a schematic diagram of a corneal flap lifter with an irrigation head of the present invention. As shown in FIG. 1 , the corneal flap lifter with an irrigation head of the present invention includes a hollow body 1 . One end of the hollow body 1 is provided with a corneal flap opening needle 2 . During corneal laser surgery, the corneal flap is lifted by the corneal flap lifting needle 2, so as to facilitate laser irradiation treatment. The other end of the hollow body 1 is provided with a flushing needle 3 . The flushing needle 3 is used for flushing the reset corneal flap to remove debris and the like during the operation. Since the hollow body 1 is hollow, irrigation liquid can be supplied to the irrigation needle 3 through the hollow body 1, so as to rinse the reset corneal flap.

The diameter of the irrigation needle 3 is larger than the diameter of the corneal flap lifting needle 2 and a plurality of irrigation holes 4 are arranged at the front end of the irrigation needle 3 . As shown in Fig. 1, in the present utility model, the plurality of flushing holes 4 are arranged along different radial directions and different axial directions of the flushing needle 3, so that the plurality of flushing holes 4 can be oriented in different directions. to spray the flushing fluid in the direction of the Compared with the traditional flushing needles that can only spray flushing fluid in a single direction, the flushing needle 3 can jet flushing fluids in different directions at the same time, so the flushing efficiency is higher and the flushing effect is better.

A connecting head 5 is arranged in the middle of the hollow body 1 . The connecting head 5 is connected with the flushing liquid storage bottle to provide flushing liquid for the flushing needle 3 . When flushing is required, the flushing can be performed only by connecting the connecting head 5 to the flushing liquid storage bottle.

In the present invention, preferably, the hollow body 1 is made of metal. More preferably, said flap lifting needle 2 and said irrigation needle 3 are also made of metal, most preferably they are made of silver.

When using the corneal flap lifter with flushing head of the utility model for corneal laser surgery, the corneal flap is lifted through the corneal flap lifting needle 2, then irradiated with laser light, and then washed with the washing needle 3 Corneal flap after repositioning. In this way, during the entire operation process, there is no need to replace instruments, which not only facilitates the operation of medical staff, but also improves operation efficiency, reduces operation time and pain of patients.

The content of the specific implementation is described for the convenience of those skilled in the art to understand and use the utility model, and does not constitute a limitation to the protection content of the utility model. Those skilled in the art can make appropriate modifications to the utility model after reading the content of the utility model. The protection content of the utility model shall be subject to the content of the claims. Without departing from the essential content and protection scope of the claims, various modifications, changes and replacements of the present utility model are all within the protection scope of the present utility model.
