Background
Anterior cervical decompression fusion (Anterior cervical decompression and fusion, ACDF) is an important surgical approach for treating cervical spondylosis, and early effective interbody fusion is an important factor affecting the clinical efficacy of ACDF. The prior commonly used interbody fusion cage obtains interbody fusion through the inter-endplate bone grafting, but clinical observation shows that the early fusion rate is not optimistic. The lateral cervical vertebra and uncinate joint area has a short distance between the upper bone surface and the lower bone surface, and the peripheral blood circulation is rich, so clinical observation shows that the healing effect of bone grafting in the area is better. Adequate contact and intimate bonding between the bone graft material and the bone graft bed is the basis for achieving satisfactory bone healing.
Patent literature (CN 203291002U) discloses a cervical vertebra uncinate joint fusion cage, but the bone grafting material of the fusion cage cannot be in close contact with uncinate joints, which is unfavorable for bone grafting fusion. In addition, the interbody fusion cage has the potential for posterior migration of bone graft material into the spinal canal, thereby increasing the risk of surgery.
Furthermore, the prior disclosed interbody fusion cage is single bone grafting in the area between end plates or at the side, so that the contact between bone grafting materials and a bone grafting bed is less, and the bone grafting fusion effect is affected.

As shown in fig. 9 and 10, two groups of inclined elastic pieces 15 are arranged on the bottom surface of the bone grafting cavity 7, one group of elastic pieces 15 is inclined towards the right, and the other group of elastic pieces 15 is inclined towards the left. When the stretching slide block 3 is stretched, the elastic sheet 15 can be pressed down in a proper direction to slide towards the bone grafting window 3; however, when the opening slider 3 slides over a certain elastic sheet 15, the elastic sheet 15 is sprung under the self elastic force to block the opening slider 3 from sliding reversely.
Example 3
This embodiment differs from embodiment 1 or 2 in that: as shown in fig. 11, 12 and 13, a separation block 14 is vertically arranged in the center of the support body 1, the separation block 14 divides the bone grafting inner cavity 7 into a left independent cavity 71 and a right independent cavity 71, and the two opening slide blocks 2 are respectively arranged in one cavity 71. The center of the separation block 14 is provided with a vertically arranged bone grafting channel 10, and the bone grafting channel 10 penetrates through the top surface and the bottom surface of the support body 1.
When in use, as shown in fig. 14 and 15, the implant can be provided between the upper and lower end plates and the two sides uncinate joints, thereby surrounding the implant in the operation space, increasing the contact area between the implant material and the implant bed and further enhancing the interbody fusion effect.
Example 4
This embodiment differs from the previous three embodiments in that: as shown in fig. 16, a baffle 11 is arranged at the rear of the bone grafting window 3 on the outer wall of the support body 1, and the baffle 11 is parallel to the chute 4.
