The wall of connector four is respectively formed connector through hole.
Arc transition connects between the wall of connector four.
The supporter is the open hollow cube of upper and lower side, and its preceding wall body bottom and rear wall body top are respectively formed plate Shape connects tenon, and preceding wall body and the corner angle apex of left wall body, right arm body junction form joint angle tenon in knuckle types, rear wall body Joint angle tenon under knuckle types is formed with the turning bottom of left wall body, right arm body junction；Between two upper joint angle tenons, with And the gap between two lower joint angle tenons forms tenon groove；Between upper joint angle tenon and top connection tenon, and under Gap between joint angle tenon and lower section connection tenon forms corner angle joint head groove.
The wall of supporter four is respectively formed supporter through hole.
Arc transition connects between the wall of supporter four.
Shape, size and the tenon of the tenon groove coordinate, and shape, size and the corner angle joint head of corner angle joint head groove coordinate.
The length of the connector and supporter, width and wall thickness are identical.
The tenon is identical with the shape size of connection tenon；Corner angle joint head, upper joint angle tenon and lower joint angle tenon Shape size is identical.
The beneficial effects of the invention are as follows：
The invention provides a kind of artificial vertebral body of joinery and its construction, and stability is high, and answers different user, can select varying number Support member, form suitable length and more agree with original vertebra, avoiding fixed position from stress concentration occur causes to connect Failure, improves the compatible degree and reliability of artificial vertebral body and human body, and can reduce the load in human vertebrae, reduces people The generation of the complication such as body vertebral levels regression.

Embodiment
Mortise and tenon type artificial vertebral body of the present invention is described in detail with reference to Figure of description and embodiment：
As shown in Fig. 1 ~ 10, a kind of mortise and tenon type artificial vertebral body, the artificial vertebral body includes two connections up and down being centrosymmetric Body 1 and at least one supporter 2 being arranged between two connectors 1；Supporter between connector 1 and supporter 2, adjacent Pass through mortise-tenon joint between 2.
The connector 1 is the open hollow cube of upper and lower side, and its preceding wall body top forms tabular tenon 4, left wall The corner angle apex that body and rear wall body and right wall body are formed with rear wall body is respectively formed knuckle types corner angle joint first 5, between two corner angle joints first 5 Gap form tongue-and-groove 7, left wall body and right wall body lower surface form multiple teeth 6.
The wall of connector 1 four is respectively formed connector through hole 3.
Arc transition connects between the wall of connector 1 four.
The supporter 2 is the open hollow cube of upper and lower side, and its preceding wall body bottom and rear wall body top are respectively formed Tabular connects tenon 9, and preceding wall body and the corner angle apex of left wall body, right arm body junction form joint angle tenon 10 in knuckle types, Wall body and the turning bottom of left wall body, right arm body junction form joint angle tenon 11 under knuckle types afterwards；Two upper connection corner angle joints Between first 10, and the gap formation tenon groove 12 between two lower joint angle tenons 11；Upper joint angle tenon 10 connects with top Between joggle first 9, and the gap formation corner angle joint head groove 13 between lower joint angle tenon 11 and lower section connection tenon 9.
The wall of supporter 2 four is respectively formed supporter through hole 8.
Arc transition connects between the wall of supporter 2 four.
Shape, size and the tenon 4 of the tenon groove 12 coordinate, and shape, size and the corner angle joint first 5 of corner angle joint head groove 13 are matched somebody with somebody Close.
