Anterior cervical lift and fixation device

Abstract

The invention discloses an anterior cervical approach lifting and fixing device. The anterior cervical approach lifting and fixing device comprises a fixing main body and a lifting body, wherein the fixing main body is provided with an upper fixing part, a connecting part and a lower fixing part, the upper fixing part is located at the upper part of the fixing main body, the lower fixing part is located at the lower part of the fixing main body, and the upper fixing part is connected with the lower fixing part through the connecting part; the lifting body is provided with a first lifting end for being connected with the upper fixing part or the connecting part, and a second lifting end for being connected with an odontoid bulge. According to the device provided by the invention, the force generated by head forerake can be overcome, the falling off during head forerake can be avoided, and the connecting and fixing effect of an operation is improved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an anterior cervical lifting and fixing device. Background technique [0002] The ring-pivot joint is located at the uppermost end of the human cervical spine, and its function is to support the human head on the cervical spine and facilitate the rotation of the human head. [0003] For some patients, if the ring-pivot joint is severely damaged, it is necessary to directly fix the head and the cervical spine. The existing method is to use a "door"-shaped connecting plate to fix the connection from the front of the neck, but the existing connection method There are following defects: [0004] When the head is in an upright state or a backward state, since the force on the front of the neck is tension, it will not affect the connection strength of the connecting plate, but if the head is tilted forward, because the front of the cervical spine is only supported by the c...

AI Technical Summary

Problems solved by technology

[0004] When the head is in an upright state or a backward state, since the force on the front of the neck is tension, it will not affect the connection strength of the connecting plate, but if the head is tilted forward, because the front of the cervical spine is only supported by the connecting plate. The connection is fixed, but the rear part is not connected and fixed. Due to the magnification of the force arm when the head is tilted forward, it is more likely to cause the connection plate to fall off, which affects the effect of the operation. If the connection is fixed from the back of the cervical spine, consider the operation risk of the operation As well as the physiological structure of the human body, this problem has not been effectively solved
