Problems solved by technology
However, the liquid in the infusion bottle will also transmit pressure to the retina, and improper control will easily lead to atrophy and necrosis of retinal cells
[0005] Another method of hemostasis is to use an additional hemostatic device to extend into the eyeball to stop bleeding. Since more instruments are used in implantation surgery, when adding an additional hemostatic device, it is very cumbersome to operate in a limited intraocular space, prolonging the operation time. The operation time is shortened, and it poses a higher challenge to the doctor

Embodiment Construction
[0041] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.
[0042] Refer below Figure 1-Figure 12 Describe the intraocular tweezers 1 of the retinal prosthesis microelectrode fixing nail 2 according to the embodiment of the present invention, the intraocular tweezers 1 are used to hold the fixing nail 2, such as Figure 5 As shown, the fixing nail 2 is used to fix the retinal prosthesis microelectrode 3, and the fixing nail 2 can fix the retinal prosthesis microelectrode 3 on the retina and sclera 4 of the eye.
[0043] The intraocular forceps 1 according to the embodiment of the present invention includes: an outer tube 10 , an inner tube 20 , a transmission member 30 and a coagulation device 50 . An axial hollow channel 11 is formed on the outer tube 10 , and the inner tube 20 is disposed in the hollow channel ...

The invention discloses intraocular forceps of a retinal prosthesis microelectrode fixing nail. The intraocular forceps comprise: an outer pipe: an axial hollow channel is formed in the outer pipe; aninner pipe: the inner pipe is arranged in the hollow channel and can axially move relative to the outer pipe; a transmission part: the transmission part is used for pushing the inner pipe to move forwards; a resetting part: the resetting part is used for pushing the inner pipe to reset backwards; and a blood coagulation device: the blood coagulation device comprises a first electrode and a secondelectrode, a thermal blood coagulation area is formed between the first electrode and the second electrode, and both the first electrode and the second electrode are arranged at the axial front end of the outer pipe and are arranged at intervals in the circumferential direction. After the fixing nail punctures the eyeball wall, the retinal capillary ruptures and bleeds, and at this time, the blood coagulation device can play a role in blood coagulation and can directly coagulate the blood of the capillary. The mode can avoid the necrosis of retinal cells in the operation and ensure the smoothand efficient operation, and the structure of the intraocular forceps is easy to manufacture and implement.
Description
technical field [0001] The invention relates to the technical field of ophthalmic nerve stimulators, in particular to intraocular tweezers for micro-electrode fixing nails of retinal prosthesis. Background technique [0002] A visual prosthesis is an implanted medical device designed to help patients with retinal or other visual organ lesions regain light and vision. The formation of normal vision is that the photoreceptor cells (cones and rods) on the retina convert light stimulation into electrical signals. Nerve impulses are transmitted to the visual cortex. A commonly used visual prosthesis design is to implant microelectrode implants into the surface of the retina (epiretinal) to help restore vision in outer retinal degeneration diseases such as retinitis pigmentosa (RP) and age-related macular degeneration (AMD), resulting in Optical hallucinations. [0003] When performing a retinal prosthesis implantation operation, it is an extremely important step to fix the mic...
