Description

Technical Field

[0001] This utility model relates to the field of ocular treatment technology, specifically to a lens removal device for cataract surgery. Background Technology

[0002] Cataract surgery is a common eye surgery used to treat cataracts. Cataracts are a condition in which the lens of the eye becomes cloudy, usually developing with age and causing blurred or decreased vision.

[0003] "Foldable lens case" typically refers to the foldable capsule used to implant an artificial lens (IOL) during cataract surgery. An IOL is a small lens used to replace the natural lens inside the eye to restore vision. IOLs are generally classified into several types, including monofocal, multifocal, and adjustable-focus lenses.

[0004] The lens can be made of rigid materials (such as polymethyl methacrylate, PMMA) or soft materials (such as silicone, acrylate, etc.), the latter of which can be folded for implantation into the eye.

[0005] Existing tweezers cannot accurately remove the lens, and the removed lens cannot be retrieved in a timely manner; therefore, they do not meet the current needs. In response, we propose a lens removal device for cataract surgery. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: This example aims to address the problem that existing tweezers 111 cannot accurately remove the crystal, and the removed crystal cannot be retrieved in a timely manner. Please refer to [link to example]. Figures 1-5 A lens removal device for cataract surgery includes an operating plate 110 and forceps 111. The operating plate 110 has an operating groove 112, and a placement groove 113 for placing the lens is formed in the operating groove 112. The placement groove 113 is connected to the operating groove 112, and a through tube 114 is installed in the placement groove 113. The forceps 111 is movably inserted into the through tube 114. A protective cover 115 for protecting the lens is movably hinged to the outside of the through tube 114. The protective cover 115 is located in the placement groove 113. An operating rod 116 is installed at the tail end of the forceps 111, and a clamp 117 is installed at the end of the forceps 111. A control sleeve 118 is provided outside the forceps 111. A control component 120 for controlling the opening and closing of the clamp 117 is provided in the operating rod 116 and the control sleeve 118.

[0026] The component includes a control ring 121 installed outside the control sleeve 118. A control rod 122 for controlling tweezers 111 is installed on the side of the control ring 121. The control rod 122 is fixedly installed on the outside of the tweezers 111. A connecting rod 123 is installed at the bottom of the control ring 121. A slider 124 is installed at the end of the connecting rod 123. A groove 125 corresponding to the slider 124 is opened on the outside of the operating rod 116. The slider 124 is slidably inserted into the groove 125.

[0027] The control sleeve 118 has a sliding groove 126 corresponding to the control rod 122, and the control rod 122 is slidably inserted into the sliding groove 126. A spring 127 is installed in the sliding groove 125, one end of the spring 127 is fixedly installed to the inner wall of the sliding groove 125, and the other end of the spring 127 is fixedly installed to the slider 124. Two clamping plates 117 are provided, and the two clamping plates 117 are symmetrically arranged. The two clamping plates 117 are made of elastic plastic plates, and protective sleeves 128 are provided on the outside of the clamping plates 117. The protective sleeves 128 are made of silicone.

[0028] The lens to be removed or processed during the surgery is placed in the placement slot 113 of the operating plate 110. The placement slot 113 is connected to the operating slot 112 via a tube 114. Forceps 111 are movably inserted into the tube 114, with the clamps 117 of the forceps 111 in a closed or slightly open state. A silicone protective sleeve 128 on the outside of the clamps 117 ensures that the lens is not damaged during the handling process. Before placing the lens, a protective cover 115 is hinged to the outside of the tube 114 to protect the lens. When the lens needs to be removed, the surgeon will open the protective cover 115 to expose the lens and the placement slot 113.

[0029] By manually adjusting the control ring 121, the control lever 122 mounted on the side of the control ring 121 pushes the outer side of the forceps 111. This, in turn, pulls the control ring 121 downwards, causing the slider 124 to slide within the groove 125 of the operating lever 116, controlling the downward movement of the forceps 111. Since the clamping plates 117 are designed as elastic plates, when the forceps 111 retract into the control sleeve 118, the two clamping plates 117 converge towards the center, ensuring the stability of the clamping plates 117 when gripping the crystal and preventing damage to the crystal from excessive force. By controlling the opening and closing of the clamping plates 117, the surgeon can precisely grip the crystal. The elastic plastic material of the clamping plates 117 and the external silicone protective sleeve 128 further ensure that the crystal is not damaged during gripping.

[0030] Once the lens is securely held, the doctor can pull the forceps 111 out of the access tube 114 and remove the lens from the placement slot 113. Due to the very fine design of the forceps 111, the combination of the control sleeve 118 and the control ring 121 allows the doctor to make fine adjustments to the opening and closing of the forceps 111 during the operation, thereby ensuring precise control when removing the lens.

[0031] If it is necessary to put the crystal back into the placement slot 113 of the operating panel 110, the doctor can again control the opening and closing of the forceps 111 through the control ring 121 to carefully put the crystal back into its original position. After the operation is completed, the protective cover 115 can be hinged closed to protect the crystal or prevent the crystal from falling out accidentally.

[0032] In this embodiment: the design of the control ring 121 and the control rod 122 allows the surgeon to precisely control the opening and closing of the forceps 111 by adjusting the control ring 121, ensuring that the crystal is not damaged when gripping and removing it. The setting of the control component 120 ensures the stability and accuracy of the forceps 111 when gripping the crystal, preventing crystal damage due to excessive force. The elastic plastic material of the clamp 117 and the silicone protective sleeve 128 ensure good protection for the crystal when gripping it, avoiding damage caused by contact with hard objects. The design of the protective cover 115 further increases the protective layer of the crystal, preventing the crystal from being damaged or displaced when not in operation.

[0033] Example 2 aims to address the issue of the protective cover 115 potentially opening or moving unexpectedly during operation. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-5 The protective cover 115 is a transparent plastic shell, and a locking block 130 is installed on the protective cover 115. The operating panel 110 has a locking slot 131 corresponding to the locking block 130, and the locking block 130 engages with the locking slot 131.

[0034] The operating panel 110 has a groove 132 for easy operation, located on the bottom side of the operating slot 112. The control lever 122 has anti-slip texture 129 on its outer surface, which is a striped pattern. The striped anti-slip texture 129 on the outer surface of the control lever 122 increases the doctor's grip, especially when frequent operation of the control lever 122 is required during surgery, effectively preventing hand slippage and ensuring the stability and safety of the operation.

[0035] In this embodiment: by installing a locking block 130 on the protective cover 115 and opening a corresponding locking slot 131 on the operating plate 110, the protective cover 115 can be more firmly fixed on the operating plate 110, ensuring that the protective cover 115 will not be accidentally opened or moved during operation, further protecting the crystal from external influences. By setting the protective cover 115 as a transparent plastic shell, the surgeon can clearly see the crystal inside the protective cover 115, avoiding the problem of not being able to directly observe the crystal before opening the protective cover 115.
