Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmic surgery, and specifically relates to a head fixing device for ophthalmic surgery. Background Technique

[0002] Ophthalmology is a discipline that studies diseases occurring in the visual system, including the eyeball and its associated tissues. Ophthalmology generally studies various ophthalmic diseases such as vitreous and retinal diseases, optometry, glaucoma and optic nerve diseases, and cataracts. When performing ophthalmic surgery, the patient's head needs to be fixed.

[0003] For example, the publication number CN114404065A discloses an adjustable head fixing device for ophthalmic surgery. A limiting pillow is vertically installed on one side of the middle of the upper surface of the bottom plate. A headrest groove is arranged on one side of the limiting pillow. Clamping plates are symmetrically installed on both sides of the headrest groove. The clamping plates are slidably installed above the bottom plate. A fastening component is installed on one side of the bottom plate. The fastening component is arranged above the headrest groove. The device has a reasonable structure and is convenient to operate. It is used by connecting the bottom plate, the limiting pillow, the headrest groove, the clamping plates, the fastening component, the sliding groove, and the transmission lead screw. When performing surgery on the patient's eyes, the head is fixed. Due to different head shapes of patients, the air bags on both sides inside the headrest groove can be adjusted and fixed according to the patient's head. The clamping plates are used to fix both sides of the head. A laser rangefinder can be used to measure the distance from the inner surface of the fixing ring to the patient's head. Then, the electric telescopic rod is used to adjust the height so that the fixing ring is fixed on the patient's forehead surface;

[0004] Generally, the head fixing devices used in ophthalmic surgery adopt the fixing methods of left - right and up - down. However, during the operation, both the operation of personnel and the use of instruments need to be above the head. Therefore, the fixing structure above the head affects the operation of the surgery and the use of instruments, which is very inconvenient.
