Embodiment Construction

[0049] For the defect or loss of the lens capsule and suspensory ligament, the current clinical solution is to suspend the intraocular lens with sutures. Disadvantages of this approach include:

[0050] (1) Not all design types of intraocular lenses can be used for suture suspension;

[0051] (2) Due to the manual fixation of sutures in IOL suture suspension, it is difficult to completely balance the tension of each IOL loop, so the intraocular lens is often displaced during or after the operation, which affects the postoperative vision of the patient;

[0052] (3) If sutures are used for fixation, the sutures may degrade in the long-term (some literature points out that more than 10 years), which may cause displacement or posterior dislocation of the intraocular lens, requiring reoperation.

[0053] For partial defect of the lens capsule or partial rupture of the zonular ligament, other current clinical solutions are to adopt the method of implanting a capsular tension ring, w...

Abstract

The invention discloses an intraocular lens capsular bag injector and an intraocular lens capsular bag injection assembly. The intraocular lens capsular bag injector comprises an injector head, an injector holding part and an injector handle, wherein the injector head comprises a first hollow pipe body, and a pipeline in the first hollow pipe body is a first pipeline; the injector holding part comprises a second hollow pipe body, and a pipeline in the second hollow pipe body is a second pipeline; the injector handle comprises a handle rod and an injection core which are connected together; theinjector head is connected with the injector holding part; the rear end of the first hollow pipe body is connected with the front end of the second hollow pipe body, and the second pipeline communicates with the first pipeline; the handle rod is located in the second pipeline, and the handle rod can slide in the second pipeline; and the injection core is located in the second pipeline and can move in the second pipeline and the first pipeline. The intraocular lens capsular bag injector is used for implanting an intraocular lens capsular bag.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intraocular lens capsular bag injector and an intraocular lens capsular bag injection assembly. Background technique [0002] The lens is composed of lens capsule, lens epithelium, crystal fiber and suspensory ligament. The lens capsule and the zonular ligament connected with the lens form the lens-iris septum system together with the iris, which separates the eyeball into anterior and posterior segments. The anterior and posterior segment structures are dissected and Physiologically important. [0003] Ophthalmic lens diseases, clinically include: Marfan syndrome, traumatic lens subluxation and total dislocation, surgery-induced lens capsule rupture and zonular ligament injury, etc. [0004] These ophthalmic lens diseases can cause defects or even absence of the lens capsule and zonules. Once the capsule is defective, it is easy to cause problems such as the inabili...
