As shown in fig. 1 to 2, the present embodiment proposes

A head fixing device for ophthalmologic treatment, comprising a support 1 and a fixing unit provided on the support 1, wherein the support 1 serves as a base on which the fixing unit is mounted, the fixing unit comprises four parts, respectively a lower jaw bracket 2 at the lower side, a head pressing member 3 at the upper side, and pressing members 4 at both sides of the action, the lower jaw bracket 2 and the head pressing member 3 have a degree of freedom relatively approaching and separating in the vertical direction, and the two pressing members 4 have a degree of freedom relatively approaching and separating in the horizontal direction. In use, the lower jaw of a patient is pressed on the lower jaw bracket 2, the head pressing piece 3 is pressed on the top of the head of the patient and fixed, and the two pressing pieces 4 are respectively clamped on the two sides of the head of the patient.

Through the setting of mandible bracket 2, head casting die 3 and two extruded articles 4, fix patient's head in four positions, can realize good fixed effect, avoid patient's head to rock, and make mandible bracket 2 and head casting die 3 can be close to each other or keep away from, two extruded articles 4 also can be close to each other or keep away from, can conveniently fix on the one hand, and can adapt to different patients, no matter be adult or children homoenergetic enough can be suitable for, the commonality is wider.

The support 1 includes base 11 and the pole setting 12 of setting on base 11, and pole setting 12 is two, and two mandible brackets 2 set up on base 11, are located the centre of two pole settings 12, and head casting die 3 then slides and sets up on two pole settings 12. One setting mode of head casting die 3 is for set up the slider respectively at the both ends of head casting die 3, is equipped with the trompil on the slider, and the slider cover is fixed in pole setting 12, realizes through the puller bolt on pole setting 12.

Two extrusions 4 are also arranged on two vertical rods 12, in order to realize the movement of the two extrusions 4, an extrusion driving device 5 is designed, a sliding block 51 slides on the vertical rods 12, the extrusions 4 are arranged on the sliding block 51 through a connecting rod 52, one end of the connecting rod 52 is hinged with the extrusions 4, the other end of the connecting rod 52 is hinged with the sliding block 51, the sliding block 51 and the connecting rod 52 are both designed into two parts, the vertical distance between the extrusions 4 and the sliding block 51 is adjusted by enabling the two sliding blocks 51 to be close to and far away from, in order to realize the movement of the two sliding blocks 51 close to or far away from, a driving screw 53 is designed, the driving screw 53 is rotatably arranged on a base 11 and is provided with two threads with opposite rotation directions, threaded holes are also arranged on the two sliding blocks 51, the two sliding blocks 51 are respectively in threaded fit with the two threads on the vertical rods 12, so that the two sliding blocks can be driven to synchronously close to or far away from each other when the driving screw 53 is rotated, which in turn drives the movement of the presser 4.

In order to enable the two extrusion parts 4 to be synchronously adjusted, a driving shaft 54 is designed on the base 11, the driving shaft 54 is horizontally arranged and transmits power to the driving screws 53 through the reversing action of the bevel gear set 55, the driving screws 53 are provided with bevel gears, the driving shaft 54 is provided with two bevel gears, and the two bevel gears on the driving shaft 54 are respectively meshed with the bevel gears on the two driving screws 53, so that the two extrusion parts 4 can be synchronously close to each other, and the use is more convenient during fixing. It should be noted that the driving shaft 54 may be designed to be manually driven, or a driving motor may be provided as a power source.
