Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a device for removing foreign matter from an eyeball. Background Art

[0002] Foreign bodies in the eye are common ophthalmic emergencies. In most cases, vitrectomy is required to remove the foreign bodies. During vitrectomy, smaller foreign bodies can be removed with forceps, and magnetic foreign bodies can be removed with magnets. However, for larger non-magnetic foreign bodies, there is currently a lack of suitable instruments to remove them from the eye during surgery.

[0003] Because the opening of our conventional foreign body forceps is limited and cannot hold larger foreign bodies, it is difficult to successfully remove the foreign body in the eye, and it can only be removed with conventional micro forceps. However, there are many disadvantages in using conventional micro forceps to remove foreign bodies. On the one hand, the foreign body is easy to slip off during the removal; on the other hand, the eyeball will be greatly deformed during the micro forceps removal process, especially the deformation of the cornea, which affects the clarity of the visual field during the operation, greatly increases the difficulty of the operation, and is easy to cause iatrogenic damage.

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Embodiment 1:

[0026] An eyeball foreign body removal device comprises a handle 1, a push-pull button 3 and a metal wire 2, wherein:

[0027] A handle 1 is hollow and has a push-pull button 3 at its upper end;

[0028] The push-pull button 3 is arranged at the upper end of the handle 1 and is connected to the inside of the handle 1. It can slide back and forth at the upper end of the handle 1, and a reset spring is also arranged on it to help the push-pull button 3 reset. One end of the reset spring abuts against the handle 1, and the other end of the reset spring abuts against the push-pull button 3. In this way, when the user pushes the push-pull button 3, the reset spring will be squeezed. When the user lets go of the push-pull button 3, the push-pull button 3 will automatically reset. A plurality of anti-slip grooves 6 are also arranged on the push-pull button 3 to prevent the user from slipping when pushing the push-pull button 3.

[0029] The metal wire 2 is made of memory steel material, one end of which is inserted into the handle 1 and connected to the push-pull button 3, and the other end of which is extended out of the handle 1 and forms a loop;

[0030] The working principle of this embodiment is that the user can control the metal wire 2 to extend more or less by controlling the forward and backward movement of the push-pull button 3, so that the size of the loop of the part where the metal wire 2 extends out of the handle 1 will become larger or smaller, so that the foreign object can be stuck and removed by reducing the size of the loop.

[0031] Embodiment 2:

[0032] The difference from the first embodiment is that in the second embodiment, an extension portion 4 is provided on the front part of the handle 1, and the diameter of the extension portion 4 is smaller than the diameter of the handle 1, so that the operator's field of vision is not affected during operation. The length of the extension portion 4 is 25 mm, and the extension portion 4 is also hollow and connected to the inside of the handle 1, so that the metal wire 2 can extend from the extension portion 4, so that the removal distance of the foreign body removal device is longer, and it can easily reach various areas in the vitreous cavity without any blind spots in operation.

[0033] Embodiment three:

[0034] The difference from the second embodiment is that in the third embodiment, a circle of magnetic parts 5 is arranged at one end of the extension portion 4 from which the metal wire 2 extends, so that when the foreign matter encountered is ferromagnetic, it can be directly removed by this removal device without other devices, and the functions are diverse.

[0035] Embodiment 4:

[0036] The difference from the first embodiment is that in the fourth embodiment, a support ring is provided at the lower end of the handle 1, so that when the user operates the foreign object removal device, the thumb presses the push-pull button 3, and one or more of the other fingers can be inserted into the support ring to provide a supporting force, which can better prevent the user from slipping when operating the push-pull button 3.

[0037] Embodiment five:

[0038] The difference from Example 1 is that in Example 5, a net bag is also provided on the loop formed at the other end of the metal wire 2, so that the foreign matter can be first caught by the loop, and then dropped into the net bag, and then put into the loop to fix the foreign matter in the net bag and take it out, which can effectively prevent the foreign matter from falling back into the eyeball after being caught.

[0039] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.

[0040] For those skilled in the art, various changes and modifications will undoubtedly be obvious after reading the above description. Therefore, the attached claims should be regarded as covering all changes and modifications to the true intent and scope of the utility model. Any and all equivalent ranges and contents within the scope of the claims should be considered to still be within the intent and scope of the utility model.
