As an improvement: the bottom plate is further provided with a headrest groove, the headrest groove is located on one side of the internal thread sleeve relative to the second moving plate, and a first spongy cushion is arranged in the headrest groove.

As an improvement: the fixed plate is of an arc-shaped structure, and a sponge cushion II is arranged on the side wall close to the bottom plate.

As an improvement: the first sliding rail and the second sliding rail are both T-shaped sliding rail structures.

As an improvement: and bolt holes are respectively arranged at the four corners of the bottom plate.

Compared with the prior art, the utility model the advantage lies in: the movable plate one of adjustment both sides is to suitable position, at the lead screw of adjustment both sides for the fixed plate can fix the chin department of head, and is fixed with the movable plate through fixing bolt, thereby is fixed with the head, and in addition, the degree of inflation that utilizes the gasbag can be with cervical vertebra jack-up, makes the patient more comfortable.

Detailed Description

The following describes the present invention with reference to the accompanying drawings.

As shown in fig. 1 and 2, a head fixator for neurosurgery comprises a bottom plate 1, wherein two opposite sides above the bottom plate 1 are respectively provided with a first sliding rail 2, the first sliding rail 2 is respectively provided with a first moving plate 3 in a matched and sliding manner, the sliding directions of the two first moving plates 3 are collinear, the first moving plate 3 is respectively provided with an internal thread sleeve 4 inclining upwards, the two internal thread sleeves 4 are oppositely arranged, the lower ends of the two internal thread sleeves 4 are respectively lapped on one side edge of the first moving plate 3 away from the center of the bottom plate 1, the first moving plate 3 is also respectively provided with a support rod 5 for supporting the internal thread sleeves 4, the internal thread sleeves 4 are respectively provided with a lead screw 6 in a matched and spliced manner, the upper end of the lead screw 6 is respectively provided with a lead screw seat 7 in a matched manner, the other side of the lead screw seat 7 is respectively connected with a fixed plate 8, the relative both sides that the internal thread sleeve pipe 4 is not equipped with to movable plate one 3 are equipped with fixing bolt 13 respectively, be equipped with in proper order on the bottom plate 1 along movable plate one 3 moving direction and with fixing bolt 13 matched with fixed slot 14, two bottom plate 1 one side between the fixed plate 8 is equipped with two slide rails 10, sliding fit is equipped with two 11 of movable plates on two 10 of slide rails, two 11 moving directions of movable plate perpendicular to movable plate one 3 remove squarely, be equipped with on two 11 of movable plates and be equipped with gasbag 12.
