TECHNICAL FIELD
[0001] The utility model relates to the technical field of auxiliary needle head, especially artificial crystal suspension operation auxiliary needle head. BACKGROUND
[0002] Artificial lens suspension operation is a kind of operation technique for implanting or re-fixing artificial lens when patient does not have enough lens capsule bag support or there is insufficient zonular band after cataract or other ophthalmic surgery. This technique fixes the support arm (haptic) of artificial lens on the sclera to ensure the stable position of artificial lens. It is a key technology for fixing artificial lens and plays a key role in restoring patient vision.
[0003] At present, the suspension suture needle head is mostly used to penetrate the sclera for suture fixation. Since it is mostly from the inner surface of the sclera, it increases the risk of eye injury and the risk of intraoperative artificial lens deviation. The existing auxiliary needle head is mostly a syringe needle head. When performing artificial lens suspension operation, it is still difficult to guide the intraocular suture out of the sclera by using the auxiliary needle head. It has the problems of low applicability and inconvenient operation. SUMMARY
[0004] In view of the defects of the prior art, the utility model provides artificial lens suspension operation auxiliary needle head, solves the problems of low applicability and inconvenient operation of the existing needle head.
[0005] To achieve the above purpose, the utility model realizes through the following technical scheme:
[0006] Artificial lens suspension operation auxiliary needle head, including needle head base, the top of needle head base is fixedly connected with needle tube, the needle tip of needle tube is provided with auxiliary needle hole, the inside of needle tube is provided with internal passage.
[0007] Preferably, the needle tube is provided with main needle hole at the needle tip by setting internal passage in the inside.
[0008] Preferably, the auxiliary needle hole is opposite to the bevel of the needle tip of the needle tube.
[0009] Preferably, the needle head base and the needle tube are communicated through the internal passage.
[0010] Preferably, the needle tube is made of stainless steel.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The application is provided with a main needle hole and a secondary needle hole, the main needle hole is a main threading hole and is mainly used for the installation operation of the suspension line, the secondary needle hole is an auxiliary threading hole and is used for the complex threading operation of the suspension line, so that the suspension line has more operation modes, the application has more threading states, and the effect of conveniently operating the suspension line is achieved.
[0013] Compared with the traditional intraocular lens suspension surgery, the surgical method can significantly reduce surgical trauma and shorten the operation time. Actual operation can be as follows: mark the corresponding position of the sclera on both sides of the patient near the corneal limbus; pass the suspension suture thread from the main needle hole; pass the auxiliary needle through the sclera from the marked position into the anterior chamber; clamp the suture thread with the intraocular forceps; pass the suspension suture through the loop fixation hole of the intraocular lens; pass the suspension suture through the secondary needle hole of the auxiliary needle; pull out the auxiliary needle from the eye and take out the suspension suture; and suture and fix the suspension suture on the surface of the sclera.
