Embodiment 1

[0032] A head fixation device includes a base 1, a support rod 2 and a head support plate 3. The inner surface of the head support plate 3 in contact with the skin is a smooth surface. In this embodiment, the head supporting plate 3 is integrally formed with the neck supporting plate 5 and the brain supporting plate 4 . According to the design of the flat state of the specimen when dissecting the specimen, the bottom of the brain support plate 4 is fixedly connected with the base 1; The support point from the neck to the head of the present invention is set according to the arc of the human body. The bottom of the brain supporting plate 4 is a head pillow point, and the brain supporting plate 4 extends from the pillow point to both sides of the head, ending at the middle vertical line; the neck supporting plate 5 extends to both sides of the neck from the bottom of the neck. The head rest can be as Figure 1 to Figure 3 As shown, from the front end to the forehead position, ...

Embodiment 2

[0034] Such as Figure 4 As shown, the edge of the brain rest 4 and / or the neck rest 5 is provided as an everted lip structure 6 . This embodiment prevents the sharp edges that appear due to the sudden cut-off of the surface of the supporting plate from causing pressure on the specimen. The second embodiment is applicable to the supporting board, especially the brain supporting board 4. The two sides of the brain supporting board 4 are designed with an upper edge structure for clamping the head. For the supporting plate that expands toward the two upper ends of the supporting plate, the lip structure 6 does not need to be designed on the upper edge. Further, the inner side of the lip structure 6 is inlaid with a cushion 7 . The cushion 7 is arranged along the lip structure 6 . The cushion 7 further eliminates the sharper, hard contact points between the device and the head.

Embodiment 3

[0036] Such as Figure 5 As shown, the head support plate 3 is made up of an inner support layer 31 and an outer support layer 32 .

[0037] Implementation Three Improvement Structure One: Refer to Image 6 As shown, the inner support layer 31 is a soft and elastic structural layer, the outer support layer 32 is a hard support layer, and the bottom surface of the inner support layer 31 is evenly provided with support blocks 9, and the support blocks 9 and the inner support layer also need to adopt soft , With elastic material. The support block 9 may be integrally injection-molded with the inner support layer 31 . The material can be Q-elastic materials such as rubber or silica gel, which can not only have a soft touch, but also have a smooth and waterproof surface. The inner support layer 31 and the support block 9 can be taken out from the outer support layer 32 for cleaning. After the inner support layer 31 is put into the outer support layer 32, the bottom surface of t...

Abstract

The invention relates to a head fixing device which comprises a base, a supporting rod and a head supporting plate, and the head supporting plate comprises a neck supporting plate and a brain supporting plate; the bottom of the brain supporting plate is fixedly connected with the base; the bottom of the neck supporting plate is fixedly connected with the top end of the supporting rod, and the lower end of the supporting rod is fixedly connected with the base; the bottom of the brain supporting plate is a head pillow point, and the brain supporting plate extends from the pillow point to the two sides of the head and stops at a middle vertical line; the neck supporting plate extends to the two sides of the neck from the bottom of the neck, the inner surface, in contact with the skin, of the head supporting plate is smooth, the supporting and fixing device with the smooth surface is adopted, the positions, in contact with the specimen, of the supporting and fixing device are in surface contact, and damage caused by the fixing structure to the specimen body is effectively avoided.

Description

technical field [0001] The invention belongs to the field of medical application anatomy, and in particular relates to a head fixation device. Background technique [0002] Applied anatomy is a relatively independent discipline developed on the basis of systematic anatomy and regional anatomy. Combining clinical operations and problems with anatomical human structure to explain or find answers to questions, this field involves brain, neck, limbs, chest and abdomen, pelvic cavity, etc., laying a solid foundation for in-depth research in clinical medicine. [0003] Before performing facial dissection, the head of the corpse needs to be fixed first. Most of the devices used for head fixation in the prior art are screw fixation. Specifically, the head is placed on the operating table first, and bolts are set from both sides of the head to support it. , top the position on both sides of the head and fix it by clamping to prevent the head from tilting to both sides. This screw-f...
