Technical Field

[0001] This invention patent relates to the field of medical device accessories, and specifically to a cataract surgery auxiliary retractor. Background Technique

[0002] In cataract surgery, the effective retraction of the eyelids is a key step to ensure the exposure of the surgical field. Traditional eyelid retraction devices mostly adopt mechanical fixed structures, which have problems such as inaccurate adjustment of the retraction amplitude and easy displacement during the operation. Some retractors lack a limiting mechanism and may cause excessive traction on the patient's orbicularis oculi muscle during long-term surgery, resulting in complications such as conjunctival edema after the operation. Existing devices generally have the defects of complex operating components and inconvenient intraoperative adjustment, which affect the surgical efficiency and increase the risk of iatrogenic injury. In addition, the use of rigid materials is likely to cause obvious foreign body sensation in patients during the operation, which is not conducive to cooperating with the surgical operation.

[0004] To achieve the above purpose, this invention patent provides the following technical solution: A cataract surgery auxiliary retractor, including a fixed plate, a retraction component, and a controller. There are two groups of the retraction components symmetrically arranged, and the controller is used to control the two groups of retraction components to open simultaneously.

[0005] Further, the retraction component includes an eyelid retraction arc plate, a transition rod, and an extension rod connected in sequence.

[0006] Further, a telescopic rod is connected between the transition rods of the two groups of retraction components, and the extension rods of the two groups of retraction components are connected through the controller.

[0007] Further, two groups of limit sliding rails are installed at one end of the fixed plate close to the extension rod, and the two groups of limit sliding rails are respectively slidably connected to the two groups of extension rods.

[0008] Further, the controller includes a rotating double-threaded tube and a threaded rod. Two groups of threaded rods with opposite helix directions are respectively fixedly connected to the sides of the two groups of extension rods close to each other, and the two ends of the rotating double-threaded tube are respectively in threaded fit connection with the two groups of threaded rods.

[0009] Further, a fixed plate is rotatably connected to the rotating double-threaded tube, and the fixed plate is fixedly installed on the fixed plate.

[0013] Next, the technical solutions in the embodiments of the present invention for a patent will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention for a patent. Obviously, the described embodiments are only a part of the embodiments of the present invention for a patent, rather than all of the embodiments. Based on the embodiments of the present invention for a patent, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention for a patent. In conjunction with the following embodiments, please refer to Figure 1 : Contents of the Embodiment The present invention relates to a cataract surgery assisting retractor, and the specific structure is described as follows. The purpose is to provide an assisting tool that is easy to operate, stable and reliable and can effectively retract the patient's eyelids to assist ophthalmologists in performing cataract surgery.

[0014] I. Overall Structure This cataract surgery assisting retractor mainly consists of three major parts: a fixing plate 1, a retracting assembly, and a controller. Among them, two sets of retracting assemblies are symmetrically arranged, respectively used to retract the upper and lower eyelids of the patient; the controller is used to precisely control the simultaneous opening and closing of these two sets of retracting assemblies to ensure the synchronism and stability during the surgery process.

[0015] II. Retracting Assembly The retracting assembly is the core part of the present invention. Each set of retracting assemblies includes an eyelid retracting arc plate 9, a transition rod 7, and an extension rod 6. The design of the eyelid retracting arc plate 9 conforms to ergonomics, and can gently and firmly retract the eyelids, reducing the compression and discomfort to the eyes. The transition rod 7 connects the eyelid retracting arc plate 9 and the extension rod 6, playing a role in transmitting force and maintaining stability. The extension rod 6 is responsible for transmitting the power of the controller to the retracting assembly to achieve the retracting action of the eyelids.

[0016] III. Telescopic Rod and Limiting Slide Rail To further enhance the flexibility and adaptability of the retractor, a telescopic rod 8 is connected between the transition rods 7 in the two sets of retracting components. The telescopic rod 8 is used to ensure that the movement trajectory of the eyelid retracting arc plate 9 does not deviate when the controller adjusts the relative movement of the eyelid retracting arc plate 9. At the same time, two sets of limit sliding rails 2 are installed at one end of the fixed plate 1 close to the extension rod 6, and the two sets of limit sliding rails 2 are respectively slidably connected to the two sets of extension rods 6. This design not only restricts the movement trajectory of the extension rod 6 and prevents it from deviating during the retracting process, but also enables the retractor to be finely adjusted according to the patient's eye shape, improving the accuracy and comfort of the surgery.

[0017] IV. Controller The controller is a key component in the present invention for controlling the opening and closing of the retracting components. It includes a rotating double-threaded tube 4 and a threaded rod 5. Two sets of threaded rods 5 with opposite helix directions are respectively fixedly connected to the sides of the two sets of extension rods 6 close to each other. The two ends of the rotating double-threaded tube 4 are respectively in threaded fit connection with the two sets of threaded rods 5. When the rotating double-threaded tube 4 rotates, due to the opposite helix directions of the threaded rods 5, the two sets of extension rods 6 will move in opposite directions simultaneously, thereby driving the retracting components to open or close. This design realizes the precise control of the retracting components, making the surgical process more stable and safe.

[0018] V. Fixed Plate and Rotational Connection The rotating double-threaded tube 4 is rotationally connected with a fixed plate 3, and the fixed plate 3 is fixedly installed on the fixed plate 1. This design allows the rotating double-threaded tube 4 to rotate freely on the fixed plate 1 without affecting the stability of the fixed plate 1. At the same time, as the support base of the entire retractor, the stability and firmness of the fixed plate 1 are crucial for the success of the surgery.

[0019] In summary, the cataract surgery auxiliary retractor of the present invention realizes the precise retraction and control of the eyelids through a clever structural design, providing a powerful auxiliary tool for cataract surgery. The retractor is not only easy to operate, stable and reliable, but also can effectively reduce the compression and discomfort to the patient's eyes, improving the accuracy and comfort of the surgery.
