Problems solved by technology
[0003] In order to adapt to the fixation of the heads of different patients, the existing head fixation devices for ophthalmic surgery are usually adjustable. The head fixation device usually does not have a mechanism to limit and fix the patient's forehead, which may cause the patient to suddenly lift the forehead during the operation and affect the operation. Therefore, there is an urgent need for an adjustable head fixation device for ophthalmic surgery. to solve the above problems

The invention belongs to the technical field of ophthalmology, in particular to an adjustable head fixing device for ophthalmologic surgery, and provides the following scheme that the adjustable head fixing device comprises a fixing shell, a rectangular groove is formed in the outer wall of the top of the fixing shell, and the inner walls of the two sides of the rectangular groove are rotationally connected with the same bidirectional lead screw; the two sides of the circumferential outer wall of the bidirectional lead screw are rotationally connected with sliding blocks through threads, and the outer walls of the two ends of the sliding blocks are slidably connected with the inner walls of the two ends of the fixed shell. According to the device, through the arrangement of a bidirectional lead screw, sliding blocks, a circular block and a fixed plate on the fixed shell, medical staff can rotate the circular block, so that the two sliding blocks get close to or away from each other, and therefore lifting of an arc-shaped pillow block is achieved, the device can adapt to people of different heights and weights, and the use range of the device is widened; and a limiting rod and a fixed spring are arranged below the arc-shaped pillow block, so that the arc-shaped pillow block can be lifted more stably, and the use safety is improved.
Description
technical field [0001] The invention relates to the technical field of ophthalmology, in particular to an adjustable head fixing device for ophthalmic surgery. Background technique [0002] The full name of ophthalmology is "eye disease specialist", which is a discipline that studies diseases that occur in the visual system, including the eyeball and its associated tissues. Ophthalmology generally studies vitreous, retinal diseases, optometry, glaucoma, optic neuropathy, cataract, etc. Ophthalmic diseases, during ophthalmic surgery, in order to prevent the patient's head from turning, it is necessary to use a fixture to fix the patient's head. [0003] In order to adapt to the fixation of the heads of different patients, the existing head fixation devices for ophthalmic surgery are usually adjustable. The head fixation device usually does not have a mechanism to limit and fix the patient's forehead, which may cause the patient to suddenly lift the forehead during the operat...
