Embodiment 1
[0031] A head fixing device includes a base 1, a support rod 2 and a head support plate 3, and the inner surface of the head support plate 3 in contact with the skin is a smooth surface. In this embodiment, the head support plate 3 is an integrally formed neck support plate 5 and a brain support plate 4 . According to the design of the lying state of the specimen when dissecting the specimen, the bottom of the brain support plate 4 is fixedly connected to the base 1 ; the bottom of the neck support plate 5 is fixedly connected to the upper end of the support rod 2 , and the lower end of the support rod 2 is fixedly connected to the base 1 . According to the present invention, the support points from the neck to the head are arranged according to the arc of the human body. The bottom of the brain support plate 4 is the head pillow point, the brain support plate 4 extends from the pillow point to both sides of the head, and ends at the mid-vertical line; the neck support plate 5...
Embodiment 2
[0033] like Figure 4 As shown, the edges of the brain support 4 and / or the neck support 5 are configured as everted lip structures 6 . This embodiment avoids the compression of the specimen by the sharp edge that appears due to the sudden cut-off of the pallet surface. The second embodiment is suitable for the support plate, especially the upper edge structure design of the two sides of the brain support plate 4 for clamping the head. For the pallet that expands to the two upper ends of the pallet, 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 . Cushion 7 further eliminates sharper, hard points of contact between the device and the head.
Embodiment 3
[0035] like Figure 5 As shown, the head support plate 3 is composed of an inner support layer 31 and an outer support layer 32 .
[0036] Implement 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, the bottom surface of the inner support layer 31 is evenly provided with support blocks 9, and the support block 9 and the inner support layer also need to be made of soft , with elastic material. The support block 9 may be a structure integrally injection-molded with the inner support layer 31 . Its material can be made of Q-bounce materials such as rubber or silicone, 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 placed in the outer support layer 32 , the bottom ...
