Description

An eye surgery lens loop guide needle

technical field

The utility model relates to the field of eye surgery, in particular to a lens loop guide needle for eye surgery.

Background technique

In the prior art, cataract patients who lost their self-support after trauma, when implanting intraocular lenses, mostly use 10-0 nylon thread to pass through the curved loops at both ends of the intraocular lens, and then suture the suture from the inside of the eyeball. It is fixed on the eyeball wall to keep the intraocular lens in a position close to the physiology and improve the vision of the patient. Due to the cutting effect of 10-0 nylon thread and the foreign body reaction of human tissue to the suture, most of the sutures lose their function in about 10 years, resulting in the dislocation of the intraocular lens, the vision loss of the patient, and the need for re-operation reduction. Younger patients face more surgeries. In recent years, in order to overcome this drawback, we have guided the curved haptics at both ends of the intraocular lens through the eyeball wall from the inside of the eye, relying on its own arc-shaped reaction force to play a fixed role, avoiding the use of nylon sutures. However, how to guide the curved haptics at both ends of the intraocular lens through the tough eyeball wall and guide them from the inside of the eye to the outside of the eye at the proper position is an urgent problem to be overcome. Currently, we use a 26G syringe needle inserted into the eye as an introducer for the intraocular lens loop. However, the 25G syringe cannot adapt to the curvature of the lens loop, which can easily lead to distortion of the intraocular lens or even breakage of the loop.

SUMMARY OF THE INVENTION

In order to overcome the existing defects, the utility model proposes a lens loop guide needle for eye surgery.

An eye surgery lens loop guide needle, comprising a needle body and a connecting seat. The needle body and the connecting seat are connected, the needle body includes a needle head, a needle shaft and a needle tail, the needle head is arranged at the front end of the needle body, and the needle shaft is connected to the needle head; The tail is connected with a needle bar, wherein the outer side of the needle bar is hollowed out, and the guiding process of the lens loop can be observed during the operation.

Further, the needle body is of hollow design, and the guide hole is arranged at the top of the needle head.

Further, the inside of the needle is provided with a non-slip convex groove to prevent the crystal loop from falling off accidentally.

Preferably, in the needle body, the needle head and the needle tail are made of stainless steel.

The utility model proposes a lens loop guide needle for eye surgery, the guide needle can adapt to the curvature of the lens loop, avoids the distortion of the artificial lens or even the break of the loop to a great extent, and can observe the lens loop during the operation. Guide the process to facilitate the process of surgery.

Description of drawings

Figure 1 is a schematic diagram of a lens haptic guide needle for ocular surgery.

Detailed ways

A lens haptic guide needle for eye surgery provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Fig. 1 shows an eye surgery lens loop guide needle, comprising a needle body 1 and a connecting seat 2, the needle body 1 and the connecting seat 2 are connected, and the needle body 1 includes a needle head 11, a needle shaft 12 and a needle tail 13. The needle head 11 is arranged at the front end of the needle body 1 , the needle bar 12 is connected to the needle head 11 ; the needle tail 13 is connected to the needle bar 12 , wherein the needle bar 12 is hollowed out on the outside.

The needle body 1 is of hollow design, and a guide hole 111 is provided at the top of the needle head 11 .

An anti-skid convex groove 112 is provided on the inner side of the needle 11 .

In the needle body 1, the needle head 11 and the needle tail 13 are made of stainless steel.

During the operation, the eyeball is first incised and the intraocular lens is put into the eye;

Then, the guide needle of the lens loop is inserted into the eye, and one end of the lens loop is inserted into the needle hole in the eye;

Finally, after seeing the lens haptics in place at the needle shaft, the needle is slowly withdrawn from the eye and the lens haptics are brought out of the eye.

Finally, it should be noted that the above embodiments are only used to describe the technical solutions of the present invention rather than to limit the technical methods of the present invention, and the present invention can be extended to other modifications, changes, applications and embodiments in application, and therefore it is considered that all such Modifications, variations, applications, and embodiments are within the spirit and teachings of the present invention.
