Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an intraocular spoon used in lens dislocation surgery. Background Technology

[0002] Lens dislocation is common due to trauma, and highly myopic patients are more prone to it after injury. If the lens dislocates into the vitreous cavity, the current surgical procedure involves first performing a vitrectomy, followed by a lens removal. In highly myopic patients, the lens often has nuclear opacity, or the patient is elderly, and the lens nucleus may appear hard during surgery, making it difficult to remove the lens with a vitrectomy tip. Therefore, heavy water is injected to allow the lens to float in the pupillary area, where it is then phacoemulsified and aspirated to remove the lens, followed by the removal of the heavy water. Phacoemulsification outside the lens capsule can damage the retina, and this procedure not only increases the operation time, but also, if the axial length of a highly myopic eye is long, the vitrectomy tip may not be able to completely remove all the heavy water, leaving heavy water droplets in the vitreous cavity or anterior chamber postoperatively, affecting the patient's visual quality, and in some cases, requiring a second surgery to remove it. Utility Model Content

[0003] This invention addresses the problem of the aforementioned lack of a lens nucleus support device by providing an intraocular spoon for lens dislocation surgery.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An intraocular spoon for lens dislocation surgery includes a housing with an inner cavity. A groove is provided in the middle of the housing and communicates with the inner cavity. An outlet is provided at the lower part of the housing and communicates with the inner cavity. An adjuster is slidably connected in the groove. A medical elastic steel wire is fixedly connected to the adjuster. An elastic ring is fixedly connected to the other end of the medical elastic steel wire. A silicone membrane is disposed inside the elastic ring.

[0006] Furthermore, toothed slide rails are provided on both sides of the slide groove, and the toothed slide rails are slidably connected to the adjuster.

[0007] Furthermore, the adjuster includes a sliding block with an open upper surface. A slider is slidably connected within the cavity. A pair of springs are fixedly connected between the slider and the bottom surface of the cavity. Toothed limit blocks are symmetrically arranged on the left and right sides of the upper surface of the slider. The two toothed limit blocks correspond to two toothed slide rails respectively. A button is fixedly connected to the middle of the upper surface of the slider.

[0008] Furthermore, a limit cover is fixedly installed on the top of the housing to prevent the regulator from derailing.

[0009] Furthermore, a rounded transition surface is provided at the connection between the bottom of the inner cavity and the outlet.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This invention controls the extension and retraction of an elastic ring via an adjustable switch. When the elastic ring extends and enters the eye, it opens under its own elasticity, forming an intraocular spoon to retrieve the dislocated hard lens from the vitreous cavity. The lens is then held in the pupillary area to act as a lens capsule, preventing ultrasound from damaging the retina and preventing the entire lens and residual debris from falling back into the vitreous cavity. This also avoids complete vitrectomy and eliminates the need for injecting heavy water into the eye to support the dislocated lens, reducing surgical risks, shortening surgical time, and improving surgical efficiency.

Detailed Implementation

[0018] To further illustrate the technical solution of this utility model, the following embodiments will be used to further explain this utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an intraocular spoon for lens dislocation surgery includes a housing 1, which has an inner cavity 2. A groove 3 is provided in the middle of the housing 1, and toothed slide rails 9 are provided on both sides of the groove 3. The toothed slide rails 9 are slidably connected to an adjuster 5. The groove 3 communicates with the inner cavity 2. An outlet 4 is provided at the lower part of the housing 1, which communicates with the inner cavity 2. An arc transition surface is provided at the connection between the bottom of the inner cavity 2 and the outlet 4 to prevent the elastic ring 7 from wearing when entering and exiting the housing 1. An adjuster 5 is slidably connected in the groove 3. A medical elastic steel wire 6 is fixedly connected to the adjuster 5. The medical elastic steel wire 6 can be bent and extended to the outlet 4. The other end of the medical elastic steel wire 6 is fixedly connected to the elastic ring 7. A silicone membrane 8 is provided inside the elastic ring 7. A limit cover 15 is fixedly installed on the top of the housing 1 to prevent the adjuster 5 from derailing.

[0020] like Figure 5 As shown, the adjuster 5 includes a sliding block 10 with an open upper surface. A slider 11 is slidably connected within the cavity. A pair of springs 12 are fixedly connected between the slider 11 and the bottom surface of the cavity. Toothed limiting blocks 13 are symmetrically arranged on the left and right sides of the upper surface of the slider 11. The two toothed limiting blocks 13 correspond to two toothed slide rails 9 respectively. A button 14 is fixedly connected to the middle of the upper surface of the slider 11. By pressing the button 14 up and down, the toothed limiting blocks 13 are pressed into the slide groove 3, enabling back-and-forth sliding. When the toothed limiting blocks 13 are not pressed, they engage with the toothed slide rails 9 to achieve automatic locking. This invention dislocates the lens during operation, facilitating subsequent surgical procedures, avoiding the step of injecting heavy water into the eye, shortening the operation time, improving the efficiency of the operation, and reducing the surgical risk.
