Description

Technical Field

[0001] This utility model relates to an internal limiting membrane forceps for internal limiting membrane tamponade, belonging to the field of medical ophthalmology technology. Background Technology

[0002] For refractory macular holes, the internal limiting membrane (ILM) needs to be removed and packed into the macular hole during surgery to close it. The ILM is extremely thin and difficult to fix within the macular hole, easily floating in the intraocular fluid. Current techniques utilize microsurgical internal limiting membrane forceps for this procedure.

[0003] Microforceps for the Internal Limiting Membrane (ILM forceps) are specialized instruments used in intraocular internal limiting membrane (ILM) removal surgery. They are typically made of stainless steel or titanium alloy and feature slender arms and fine occlusal surfaces. Their principle is to use the opening and closing motion of the forceps to grasp and fix intraocular tissue. Microforceps generally consist of a handle, two jaws, and a connecting guide rod. The jaws open and close by moving the handle. The jaws are usually a double-clamp design with the clamping surfaces bent inwards. In use, the microforceps are first inserted into the eye, and the internal limiting membrane is aligned using a microscope. Then, the jaws are opened and positioned on the internal limiting membrane. The jaws are then closed by moving the handle to grasp the internal limiting membrane. After grasping the internal limiting membrane, the surgeon can perform surgical operations such as peeling, moving, and removing the membrane. After completion, the gripping of the internal limiting membrane is released by unlocking the jaws. In summary, microsurgical internal limiting membrane forceps achieve the removal, movement, and extraction of the internal limiting membrane through the opening and closing of the grippers, the locking and unlocking of the fixation mechanism. The design and operation of this instrument allow for more precise, safe, and effective internal limiting membrane removal surgery.

[0004] However, microscopic internal limiting membrane forceps are not convenient to use when performing internal limiting membrane tamponade within the macular hole. Specifically, because the gripping surfaces of the claws are curved inward, the internal limiting membrane cannot be fixed after being grasped and placed into the macular hole, and may drift away in the fluid-filled environment of the eye. Utility Model Content

[0005] This invention provides a forceps for internal limiting membrane tamponade, which can grasp and tamp the internal limiting membrane, particularly for internal limiting membrane tamponade under the macular hole.

[0006] To achieve this objective, the present invention provides the following technical solution:

[0007] The first aspect of this utility model provides an internal limiting membrane forceps for internal limiting membrane tamponade, comprising a gripping part, a handle, a connecting guide rod, and two grippers. One end of the connecting guide rod is connected to the gripping part, and the other end is connected to the grippers. The handle is disposed on the gripping part, and the opening and closing movement of the handle causes the two grippers to open or close. The ends of the two grippers both protrude outward.

[0008] In this invention, the internal limiting membrane forceps used for internal limiting membrane tamponade mainly improves the gripper structure. Other structures, including but not limited to the structure of connecting guide rods to control the grippers, are the same as those in the prior art.

[0009] In this invention, the ends of the grippers all protrude outwards. When the grippers of the internal limiting membrane forceps used for internal limiting membrane tamponade are closed, they can grasp the internal limiting membrane. When the grippers are open, the internal limiting membrane forceps bury the internal limiting membrane under the edge of the macular hole and prevent it from drifting away.

[0010] Preferably, the gripper is L-shaped.

[0011] Preferably, the short side of the L-shaped gripper is narrower on the outside and wider on the inside.

[0012] In this invention, the grippers are L-shaped with the short side being narrower on the outside and wider on the inside. When the inner limiting membrane is filled in and the inner limiting membrane forceps are opened, the outward-facing short side of the L-shape can extend under the edge of the macular hole, thereby burying the edge of the inner limiting membrane under the edge of the macular hole.

[0013] Preferably, the long side of the L-shaped gripper is 2-3 mm long, and the short side is 0.2-0.5 mm long.

[0014] Preferably, the thickness of the short side of the L-shaped gripper is 0.01-0.02 mm at its maximum and 0.001-0.01 mm at its minimum.

[0015] Preferably, the thickness of the long side of the L-shaped gripper is 0.1-0.5 mm.

[0016] In this invention, the thickness of the short side of the L-shaped gripper is 0.01-0.02 mm at its maximum and 0.001-0.01 mm at its minimum. When the inner limiting membrane is inserted and the inner limiting membrane forceps are opened, the outward-facing short side of the L-shape extends into the edge of the macular hole, making it easy to insert the short side under the edge of the macular hole, thus facilitating the embedding of the inner limiting membrane under the edge of the macular hole.

[0017] Preferably, the contact surfaces of both grippers when closed are smooth, so that the inner limiting membrane can be easily separated from the tweezers after being placed into the macular pore.

[0018] Preferably, the grippers are made of metal.

[0019] The method of using the internal limiting membrane forceps for internal limiting membrane tamponade of this invention is briefly summarized as follows:

[0020] 1. First, sterilize the internal limiting membrane forceps with high-pressure steam to ensure thorough sterilization;

[0021] 2. Before the procedure, the patient should keep their eyes stable. Anesthetic eye drops can be used to reduce the patient's blinking reflex.

[0022] 3. Use sterile gauze or cotton balls to wipe away secretions or dirt from the surface of the patient's eyeball. At the same time, make sure your hands are also clean.

[0023] 4. Once you are ready to perform the operation, slowly grasp the internal limiting membrane forceps, ensuring your hand remains steady;

[0024] 5. Gently place the grippers of the internal limiting membrane forceps on the internal limiting membrane and clamp it with moderate pressure;

[0025] 6. Ensure the contact point between the internal limiting membrane forceps and the internal limiting membrane, and gently grasp the internal limiting membrane;

[0026] 7. Insert the gripper holding the internal limiting membrane into the macular aperture, release the gripper, and let the internal limiting membrane fall naturally and cover the macular aperture. At this time, the short side is still covering the internal limiting membrane to prevent it from drifting away.

[0027] 8. The short, outward-facing L-shaped side of the gripper extends into the edge of the macular hole, burying the edge of the internal limiting membrane below the edge of the macular hole;

[0028] 9. After the operation is completed, gently and slowly remove the internal limiting membrane forceps;

[0029] 10. Before cleaning the internal limiting membrane forceps and proceeding to the next step, soak them in disinfectant.

[0030] Compared with the prior art, the beneficial effects and significant progress of the technical solution of this utility model are as follows: The internal limiting membrane forceps of this utility model, used for internal limiting membrane tamponade, can grasp and tamponade the internal limiting membrane, especially burying the edge of the internal limiting membrane under the edge of the macular hole. When the grippers of the internal limiting membrane forceps are closed, they can hold the internal limiting membrane; when the grippers are open, the internal limiting membrane can naturally cover the macular hole, and the outward L-shaped short side extends into the edge of the macular hole, burying the edge of the internal limiting membrane under the edge of the macular hole.

The handle 3 is disposed on the gripping part 4, and the opening and closing movement of the handle 3 causes the two grippers 1 to open or close. The ends of the two grippers 1 protrude outward.

[0046] In this embodiment, the gripper 1 is L-shaped.

[0047] In this embodiment, the long side of the L-shaped gripper 1 is 2.5 mm long and the short side is 0.25 mm long.

[0048] like Figure 2 As shown, the short side of the L-shaped gripper 1 is narrower on the outside and wider on the inside, similar to a right trapezoid. The narrow part of the short side of the L-shaped gripper 1 can extend beyond the edge of the macular hole, burying the edge of the internal limiting membrane under the edge of the macular hole.

[0049] In this embodiment, the thickness of the short side of the L-shaped gripper 1 is 0.01 mm at its maximum and 0.005 mm at its minimum.

[0050] In this embodiment, the cross-section of the long side of the L-shaped gripper 1 is a right trapezoid.

[0051] In this embodiment, the thickness of the long side of the L-shaped gripper 1 is 0.25 mm at its maximum and 0.15 mm at its minimum.

[0052] In this embodiment, the contact surfaces of the two grippers 1 when they are closed are both smooth surfaces.

[0053] In this embodiment, the gripper 1 is made of metal.

[0054] like Figure 1 As shown, the structure of the gripping part 4, handle 3, and connecting guide rod 2 of the internal limiting membrane forceps in this embodiment is the same as that of the prior art, except that the two grippers 1 have been improved.

[0055] Example 2

[0056] like Figure 3 As shown, the internal limiting membrane forceps used in Example 1 for internal limiting membrane tamponade were used for internal limiting membrane tamponade. The method of use is briefly summarized as follows:

[0057] Step 1: First, sterilize the internal limiting membrane forceps with high-pressure steam to ensure thorough sterilization;

[0058] Step 2: Before the procedure, the patient should keep their eyes stable. Anesthetic eye drops can be used to reduce the patient's blinking reflex.

[0059] Step 3: Use sterile gauze or cotton balls to wipe away secretions or dirt from the surface of the patient's eyeball. At the same time, make sure your hands are also clean.

[0060] Step 4: Once you are ready to perform the operation, slowly grasp the internal limiting membrane forceps, ensuring your hand remains steady.

[0061] Step 5: Gently place the gripper 1 of the internal limiting membrane forceps on the internal limiting membrane 5 and clamp it with moderate pressure;

[0062] Step 6: Ensure the contact point between the internal limiting membrane forceps and the internal limiting membrane 5, and gently grasp the internal limiting membrane 5;

[0063] Step 7: Insert the gripper 1 that holds the internal limiting membrane into the macular pore, release the gripper 1, and let the internal limiting membrane 5 fall down naturally and cover the macular pore. At this time, the short side is still covering the internal limiting membrane to prevent the internal limiting membrane from being drifted away.

[0064] Step 8: The short L-shaped side of the gripper 1 extends outward into the edge of the macular hole, burying the edge of the inner limiting membrane 5 under the edge of the macular hole.

[0065] Step 9: After the operation is completed, gently and slowly remove the internal limiting membrane forceps;

[0066] Step 10: Before cleaning the internal limiting membrane forceps and proceeding to the next step, soak them in disinfectant.

[0067] In summary, the improved internal limiting membrane forceps of this invention embed the internal limiting membrane beneath the edge of the macular hole, preventing it from drifting away.
