Description

Technical Field

[0001] The utility model relates to the technical field of intraocular lenses, in particular to an intraocular lens injector that can be stably implanted. Background Technique

[0002] An intraocular lens (IOL) is an artificial lens used to replace the natural lens in a human eye when suffering from cataracts or other diseases to correct refractive errors of the eye. Since the material of the intraocular lens itself is flexible and its size is small, it is difficult to directly perform surgical operations on it. Therefore, an auxiliary medical device is needed to implant it into the eye through a minimally invasive surgical opening.

[0003] During the delivery process, damage to the IOL is often attributed to the fact that when the plunger tip contacts and advances the IOL through the implanting device, the plunger tip may accidentally scratch or tear the IOL. At the end part of the IOL advancement stage, the IOL is simultaneously compressed and pushed through the narrowed implanting device channel. The force required to push the IOL through the implanting device must increase, the probability of IOL damage increases, and the end stage is a critical stage, in which the forces acting on the IOL are at their maximum values. At the same time, due to the need for extrusion, the IOL will instantaneously unfold from the curled state at the moment of export, generating a relatively large impact force, which causes certain harm to the patient's eyes and aggravates the postoperative reaction.

[0004] In order to solve the above problems, this case was born. Content of the Utility Model

[0018] The present utility model will be further described in detail below with reference to the drawings and embodiments.

[0019] As Figures 1 - 3 shown: An artificial lens implantator that can be stably implanted includes a barrel body 1 and a push rod 2 adapted to the barrel body 1. The push rod 2 and the barrel body 1 are connected in a piston manner to form a syringe. A flip cover 5 is provided on the barrel body 1, and a box cavity can be movably placed in the flip cover 5. The artificial lens is pre-placed in the box cavity. A through groove axially consistent with the push rod 2 is provided at the box cavity for the artificial lens to be smoothly extruded.

[0020] A soft cavity 7 is provided at the front end position of the implanting head 4. The soft cavity 7 connects the implanting head 4 and the outlet 10, and the bottom of the soft cavity 7 is a support position 8. The bottom support position 8 is made of the same material as the implanting head 4, and is used to connect the front outlet 10 and the implanting head 4 and support the soft cavity 7.

[0021] The soft cavity 7 is made of conventional flexible materials, which can reduce the driving force. That is, the force required for the intraocular lens to be implanted when passing through the front-end converging outlet 10 must be increased. Especially at the end stage, the force acting on the intraocular lens is at its maximum. The setting of the soft cavity 7 enables the intraocular lens to have a surplus of force while being converged and limited, and the driving force can be reduced to a certain extent.

[0022] Secondly, the tip of the push rod 2 may apply too much force, posing a risk of scratching or tearing the intraocular lens. Therefore, a silicone head 3 is provided at the inner end of the push rod 2 to form a certain force application buffer when contacting the intraocular lens.

[0023] When the intraocular lens is exported, it will instantaneously unfold from the curled state, generating a relatively large impact force, which may cause certain harm to the patient's eyes. Therefore, in this embodiment, a micro buffer notch 6 is provided at the outlet 10. The buffer notch 6 is strip-shaped, and the size of the notch gradually expands along the axial direction near the outlet 10, giving the intraocular lens a slight unfolding space and delaying / stretching the unfolding speed of the lens to a certain extent, reducing the degree of harm to the patient's eyes.

[0024] As described above, based on the embodiments as inspiration, through the above description, relevant staff can make various changes and modifications completely within the scope of not deviating from the idea of this invention. The technical scope of this utility model is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
