Background
Intervertebral fusion is a common treatment means for spinal diseases, and is widely applied to the treatment of various spinal diseases including congenital malformation of spinal column, degenerative changes, tumors, fractures and the like. Generally, cervical fusion, thoracic fusion and lumbar fusion can be classified according to anatomical morphology. In the 50 s of the 20 th century, Robinson and Smith developed anterior cervical decompression bone grafting fusion, and the cervical fusion technology was rapidly developed.
The traditional bone grafting method of the anterior cervical spine is autologous iliac bone grafting, but has the defects of supply region pain, local nerve injury, insufficient bone mass and the like; the metal interbody fusion cage is reliable in fixation, can better maintain the intervertebral space height and physiological curvature, but cannot be absorbed by a human body, and the spongy bone absorption and the fusion cage collapse can be caused due to stress shielding; in recent years, polymer fusion devices such as PEEK (polyetheretherketone) are widely used, have good biocompatibility, and have mechanical properties equivalent to those of cortical bone, so that sound stress shielding can be reduced. However, the PEEK material has poor osseointegration capability after being implanted into a body because the surface of the PEEK material is hydrophobic. The bone structure and components of the allogeneic fusion bone block and the bone of a patient are very similar, and the bone fusion effect is second to that of autogenous bone and can make up for the defect of insufficient autogenous bone.

Detailed Description
The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the utility model provides a chimeric allogeneic cervical vertebra fusion bone piece, compared with the traditional cortical bone fusion cage, the fusion bone piece of the embodiment has the biomechanical property of cortical bone and the bone conduction property of cancellous bone. Wherein the cortical bone can play a certain supporting role, the porous cancellous bone is favorable for the growth of cells and tissues, the fusion rate is improved, and the fusion cage is applied to the cervical vertebra fusion bone grafting, so that the bone fusion can be well realized without adding extra bone grafting materials.
This fuse bone piece is concrete including the cortical bone 1 that plays supporting role to and do benefit to the porous cancellous bone 2 that cell and tissue grow into, porous cancellous bone 2 is in the same place with 1 tenon fourth of the twelve earthly branches of cortical bone, and the upper and lower surface of cortical bone 1 all is equipped with a plurality of wear-resisting sawtooth 3, wear-resisting sawtooth 3 is used for increasing the frictional force between cortical bone 1 and the upper and lower cone.
As the first advantage of this embodiment, the cortical bone 1 has certain mechanical support performance, and the wear-resisting sawtooth 3 of upper and lower face has increased the frictional force that fuses the bone piece and upper and lower vertebral plate, can guarantee the mechanical stability after the material is implanted, and porous cancellous bone 2 has superior bone conduction performance, does benefit to the cell and organizes to grow into, can avoid present cervical vertebra fusion device need get autologous bone or other grafting bone material and fill the drawback.
As a second advantage of the present embodiment, the bone block is prepared by combining the allogeneic cortical bone 1 and the porous cancellous bone 2 by using a mortise and tenon technique, and the embedded allogeneic cervical fusion bone block is prepared without adding other bonding agents and other substances, so that the bone block is safer to use, has no side effects in material aspect, and reduces pain of patients.
The specific mortise and tenon principle is as follows: the medial surface of porous cancellous bone 2 is equipped with tenon buckle 5, the medial surface of cortical bone 1 is equipped with the fourth of the twelve earthly branches and decides recess 6, the size of the fourth of the twelve earthly branches and deciding recess 6 is the same with the size of tenon buckle 5, and the fourth of the twelve earthly branches and deciding recess 6 and correspond the marginal position of contact tenon buckle 5 lower surface and be equipped with blend stop 7.
The circumferential side face of the upper end of the tenon buckle 5 is provided with a protruding strip ring 8, and the inner surface of the mortise fixing groove 6 is provided with a thin clamping groove 9 at the same height position.
As a third advantage of the embodiment, the mortise and tenon of the embodiment is more stable, and the porous cancellous bone 2 and the cortical bone 1 can be prevented from being dislocated and falling off, so that the use stability is increased, and the service life is prolonged.
The specific implementation mode is as follows: as is well known, a common mortise and tenon joint is a connection mode that two components are combined by concave-convex parts, wherein a convex part is called a tenon (or called a tenon), and a concave part is called a mortise (or called a mortise and a mortise), in the embodiment, the tenon buckle 5 of the porous cancellous bone 2 is combined with the mortise and tenon fixing groove 6 of the cortical bone 1, so that a stable component is formed in the left-right direction, but because the bone block of the embodiment is applied to the cervical vertebra of a human body, friction and shaking often occur, the labor fatigue is high, and therefore, in order to prevent the porous cancellous bone 2 and the cortical bone 1 from being separated from each other in the up-down direction, a limiting part for the tenon buckle 5 is specially added in the mortise and tenon fixing groove 6.
Install recess 6 when deciding in the fourth of the twelve earthly branches of cortex bone 1 with the tenon buckle 5 of porous cancellous bone 2, the blend stop 7 of recess 6 lower surface is decided in the fourth of the twelve earthly branches limits porous cancellous bone 2 to move down, protruding circlip 8 card of tenon buckle 5 upper end is in the thin draw-in groove 9 of recess 6 is decided in the fourth of the twelve earthly branches, restrict porous cancellous bone 2 and move up, consequently, through injecing the upper and lower position of tenon buckle 5, can guarantee that porous cancellous bone 2 and cortex bone 1 can not take place the dislocation of direction from top to bottom, consequently, increase the stability in use, and prolonged service life.
In addition, the barrier strip 7 of the embodiment can not completely cover the lower surface of the tenon buckle 5, so that the porous structure of the tenon buckle 5 can be conveniently fused with cells and tissues, and the fusion degree is improved.
Preferably, the cortical bone 1 is provided with an inner groove 4 on the side for easy clamping, so as to facilitate clamping of surgical tools and improve the operability of surgical operation.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
