Adjustable head fixing device for ophthalmic surgery

Abstract

The invention discloses an adjustable head fixing device for ophthalmic surgery, and belongs to the technical field of ophthalmic surgery. The adjustable head fixing device includes a base, a first groove is formed in the upper surface of the base, and the lower surface of the inner wall of the first groove is overlapped with the lower surface of a concave panel, a threaded sleeve is slidably connected in the first groove, and the inner wall of the threaded sleeve is threadedly connected with the surface of the concave panel. According to the adjustable head fixing device for ophthalmology surgery, by arranging the base, a pillow block, a threaded rod and a second turntable, the second turntable is first rotated so that the second turntable drives a slider to move left and right through the threaded rod, a turning block rotates through a pin shaft, the angle of the pillow block is shifted by a telescopic plate, the pillow block starts to slide on balls on the concave panel, and the left and right deflection angles of a head can be adjusted by turning in different directions and the number of turns. The left and right angles of the head can be adjusted finely in time to enable the operation to more convenient and safe for staff.

Description

technical field [0001] The invention belongs to the technical field of ophthalmic surgery, in particular to an adjustable head fixation device for ophthalmic surgery. Background technique [0002] The full name of ophthalmology is ophthalmology department. Ophthalmology is a discipline that studies diseases that occur in the visual system, including the eyeball and its associated tissues. Common ophthalmic diseases include central serous retinopathy, dry eye, sympathetic ophthalmia, night blindness, Blindness, amblyopia, astigmatism, trachoma, cataract, diabetic retinopathy and conjunctivitis, etc., before performing ophthalmic surgery on the patient, it is necessary to fix the patient's head first. The belt is fixed directly, and the existing head fixing device is inconvenient. During the operation, the operation angle needs to change with the change of the cutting and the internal angle of the eye, and it is impossible to fine-tune the left and right angles of the head in ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable head fixation device for ophthalmic surgery, which solves the inconvenience of the existing head fixation device. The change of the angle leads to the change of the operation angle, and it is impossible to fine-tune the left and right angles of the head in time, which brings some inconvenience to the staff.
