Description

Technical Field

[0001] The present application relates to the field of medical devices, and more specifically, to an anterior chamber lighting nucleus chopping hook with optical fiber and a method of using the hook. Background Art

[0002] Cataract is the most common blinding eye disease. Currently, surgical treatment has become the first choice for cataract treatment due to its mature technology and significant efficacy. The current mainstream surgical methods include intracapsular cataract extraction, extracapsular extraction, and phacoemulsification cataract extraction. Among them, phacoemulsification has become the most commonly used surgical method in urban areas due to its minimally invasive, short operation time, and fast postoperative recovery. During phacoemulsification surgery, the surgeon needs to hold the super nipple phacoemulsification lens nucleus in one hand and the chop hook (chop) in the other hand to help separate and rotate the nucleus block. Among them, the transparency of the cornea has an important impact on the surgeon's field of vision, affecting the surgeon's observation of the details of the anterior chamber, and is crucial to the safety and success of the operation. Some elderly patients have problems such as a small number of corneal endothelial cells and abnormal functions. Therefore, intraoperative ultrasonic energy is prone to corneal edema, as well as corneal edema caused by acute angle-closure glaucoma, which affects the surgical field of vision and operation. In addition, a small number of patients with corneal clouding, macules, and white spots will also affect the surgeon's field of vision.

[0003] Therefore, how to improve the surgical field of view and clarity of cataract surgery is particularly important to improve the safety and success rate of cataract surgery. Summary of the invention

[0023] Description of the accompanying drawings: 1. Hook handle; 2. Hook arm; 3. Core chopping tip; 4. Optical fiber; 5. Light source. DETAILED DESCRIPTION

[0024] The structure and effect of the present application are further described in detail below in conjunction with the embodiments. It is to be understood that the specific embodiments described herein are only used to explain the invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention rather than the entire structure are shown in the accompanying drawings.

[0025] In ophthalmic cataract surgery, a transparent cornea is crucial to the success and safety of the surgery. Edema and scarred corneas will affect the surgeon's observation and judgment of the surgeon's condition, affect the surgeon's operation, increase the difficulty of the surgery, and bring more risks to the surgery. For edema and scarred corneas, the internal lighting fiber entering the anterior chamber can improve the surgical field. Conventional cataract surgery will make two incisions on the cornea. The surgeon holds the ultrasonic nipple and the chopping hook in both hands, enters the anterior chamber from the main incision and the side incision, and cooperates with the operation of ultrasound to break and remove the nucleus of the lens. For edema and scarred corneas, the internal lighting entering the anterior chamber can improve the surgical field. The device of the present invention aims to invent an anterior chamber lighting chopping hook with optical fiber by combining the optical fiber with the chopping hook. It does not need to increase the corneal incision and does not affect the operating habits of the surgeon. It can make the field of view of some difficult cataract surgeries with corneal abnormalities clearer and increase the safety of the surgery. The device consists of five parts: a hook handle, a hook arm, a chopping tip, an optical fiber and a light source.

[0026] Example

[0027] This embodiment discloses an anterior chamber illumination nucleus chopping hook with optical fiber, referring to Figure 1 The anterior chamber illumination nucleus chopping hook with optical fiber 4 comprises a hook handle 1, a hook arm 2, a nucleus chopping tip 3, an optical fiber 4 and a light source 5 which are connected in sequence. The hook handle 1, the hook arm 2 and the nucleus chopping tip 3 are all provided with channels for the optical fiber 4 to pass through, and the channels are interconnected. After the optical fiber 4 passes through the channel, it provides illumination for the working end of the nucleus chopping tip 3. The end of the optical fiber 4 close to the hook handle 1 is connected to the light source 5.

[0028] In a preferred embodiment, the inner wall of the channel of the hook handle 1, the hook arm 2 and the chopping tip 3 is provided with a protective layer, and / or the outer side of the optical fiber 4 is provided with a protective layer to reduce the friction and damage of the optical fiber 4 during the transmission process. The protective layer material is a material commonly used in the field of medical devices, including thermoplastic polyurethane elastomer rubber (TPU), polyimide (PI) or polytetrafluoroethylene (PTFE), and can also be selected from a protective layer of a soft material such as silicone rubber.

[0029] In a preferred embodiment, the light source 5 is provided with an adjustment function, including adjusting brightness and color temperature, to adapt to different surgical requirements. The operating doctor can adjust the light source 5 according to the actual surgical environment to improve the intraoperative visual field and clarity.

[0030] In a preferred embodiment, the light source 5 can be arranged on the hook handle 1 or can be arranged independently. When the light source 5 is arranged on the hook handle 1, it can be arranged on the hook handle 1 through an existing detachable structure, so as to facilitate the replacement of the light source 5 later.

[0031] The method of using the anterior chamber lighting nucleus chopping hook with optical fiber in this embodiment is: turn on the light source, and under the light guiding effect of the optical fiber, the tip end of the nucleus chopping tip emits light, thereby providing a better intraoperative field of view and clarity without changing the inherent operating habits of the surgeon.

[0032] The beneficial effects of the present invention are:

[0033] During cataract surgery, patients with concomitant corneal diseases are often encountered. The opaque cornea poses a huge challenge to cataract surgery and brings many obstacles, such as:

[0034] An opaque cornea will affect the surgeon's observation of the anterior chamber, such as the condition of the capsular bag and the suspensory ligament. The process of tearing off the anterior capsule during cataract surgery is very delicate. One careless move can easily cause the capsular bag to tear, which can easily lead to vitreous anterior chamber herniation, the lens falling into the vitreous cavity, or affect the subsequent implantation of the artificial lens. Some patients with high myopia and glaucoma often have abnormalities of the suspensory ligament, and the judgment of the condition of the suspensory ligament determines the method of lens implantation.

[0035] An opaque cornea will affect the surgeon's phacoemulsification operation. During cataract surgery, the lens needs to be split into multiple nuclei using ultrasound. The surgeon needs to accurately control the energy of the phacoemulsification and the suction process of the phacoemulsification head. An unclear surgical field may cause the iris tissue to be accidentally inhaled during the phacoemulsification and cortical aspiration, leading to bleeding and increasing the trauma of the surgery. It may also cause the capsule to be accidentally inhaled, causing the capsule to rupture and affecting the subsequent implantation of the intraocular lens.

[0036] The above situation has an adverse effect on cataract surgery. This patented product can solve the above problems well. By designing an anterior chamber lighting nucleus chopping hook with optical fiber, it can improve the intraoperative visual field of a small number of patients with corneal cloudiness, macules and leukoplakia, help to more accurately judge the intraoperative situation, and increase the safety of surgery and treatment effect.

[0037] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed. However, as long as it is within the scope of the claims of the present application, it shall be protected by the patent law.
