Abstract
The utility model relates to medical instrument technical field, concretely relates to a transverse connecting device for internal fixation of spine, include: two cross links, the cross link includes the hook body and the stem that are connected with each other, fixed part is used for locking the stem of two cross links each other, when the fixed part is locked can force two stems to move towards each other, make two stem each other and produce locking force. The utility model discloses through setting up first limiting portion and second limiting portion on the stem of two cross links respectively, upgrade the stem of cross link originally smooth surface to the interlocking surface structure of carding, utilize the movement of each other when locking of fixed part, force first limiting portion active embedding nearest neighbor second limiting portion, on the basis of friction locking combination mechanical interlock, mechanical interlock structure still keeps certain locking force after the loosening of fixed part, significantly reduces the risk of postoperative failure.
