Abstract

The utility model relates to a zero-notch cervical interbody fusion cage with anchoring screw holes, which comprises a fusion block, wherein one end of the fusion block is provided with two anchoring screw holes, the two anchoring screw holes respectively face to the upper end and the lower end of the fusion block, and the insides of the two anchoring screw holes are both in threaded connection with anchoring screws, so that the zero-notch cervical interbody fusion cage has the following advantages: the fusion cage is placed in the intervertebral space, no matter is exposed at the front edge of the vertebral body, and only the front edge of the self vertebral body is provided, so that the swallowing feeling of the esophagus cannot be influenced; the intervertebral fusion cage is directly connected through screws, steel plates are not needed, the number of used materials is reduced, and the implantation and fixation process of the intervertebral fusion cage is simplified.

Description

Zero-notch cervical interbody fusion cage with anchoring screw holes

Technical Field

The utility model relates to the technical field of cervical vertebra repair, in particular to a zero-incisura cervical interbody fusion cage with anchoring screw holes.

Background

The existing interbody fusion cage and fixing system applied to anterior cervical spine surgery are mainly a fusion cage and plate nail system, the problems of swallowing difficulty caused by the early steel plate at the front edge of the vertebral body, high material cost and the like exist, the interbody fusion cage is simply placed in some cases, and the condition of fixing steel plate screws is not placed, but when the problem of cervical curvature causes the plane inclination of interbody fusion end plates to be serious, or when the interbody fusion cage needs to be placed under multi-segment pressure reduction, the conditions of loosening and displacement of the fusion cage, poor fusion rate and the like often exist without the fixation of the steel plate screws, and serious consequences are caused.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is that the connection is carried out through steel plates, the swallowing is influenced in the early stage, and the zero-incisura cervical interbody fusion cage with the anchoring screw holes is provided and is placed in the intervertebral space, no object is exposed at the front edge of the vertebral body, and the swallowing feeling of the esophagus cannot be influenced only by the front edge of the self vertebral body; the intervertebral fusion cage is directly connected through screws, steel plates are not needed, the number of used materials is reduced, and the implantation and fixation process of the intervertebral fusion cage is simplified.

The technical scheme adopted by the utility model for solving the technical problem is as follows: the utility model provides a take zero notch cervical vertebra interbody fusion cage of anchoring screw, includes the fusion piece, two anchoring screw holes have been seted up to the one end of fusion piece, two anchoring screw hole is respectively towards the upper and lower both ends of fusion piece, two equal threaded connection in inside of anchoring screw hole has anchoring screw.

As a preferred technical scheme of the utility model, the upper end and the lower end of the fusion block and one end far away from the anchoring screw hole are both provided with anti-skidding teeth.

As a preferable technical scheme of the utility model, a through hole is arranged in the middle of one end of the fusion block, which is far away from the anchoring screw hole, in a penetrating manner.

The utility model has the following advantages: the fusion cage is placed in the intervertebral space, no matter is exposed at the front edge of the vertebral body, and only the front edge of the self vertebral body is provided, so that the swallowing feeling of the esophagus cannot be influenced; the intervertebral fusion cage is directly connected through screws, steel plates are not needed, the number of used materials is reduced, and the implantation and fixation process of the intervertebral fusion cage is simplified.

Detailed Description

The technical scheme of the utility model is clearly and completely described in the following with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model will be further explained with reference to the drawings.

Referring to fig. 1-2, the zero-notch cervical interbody fusion cage with anchor screw holes of the present invention comprises a fusion block 1, wherein one end of the fusion block 1 is provided with two anchor screw holes 2, the two anchor screw holes 2 respectively face the upper and lower ends of the fusion block 1, the two anchor screw holes 2 are internally and respectively in threaded connection with a rivet screw 3, after the two anchor screws 3 pass through the anchor screw holes 2, inserted into the upper and lower sides of the cervical vertebrae and fixed directly by the anchoring screws 3 without additional steel plates, reducing the use of materials, avoid influencing the esophagus and swallow and feel, the upper and lower both ends of fusion piece 1 and the one end of keeping away from anchoring screw 2 all are equipped with anti-skidding tooth 4, prevent that fusion piece 1 from shifting between two cervical vertebrae, and the one end middle part that anchoring screw 2 was kept away from to fusion piece 1 runs through and is equipped with through-hole 5 for implant artificial bone or autologous bone, play the effect that the intervertebral space fuses.

Specifically, when the utility model is used, the fusion block 1 is placed between two cervical vertebra blocks, the fusion block 1 is driven into cervical vertebra through the anchoring screw 3, and the fusion block 1 is fixed between the two cervical vertebra blocks, and the fusion block 1 is only added between the two cervical vertebra blocks without using an additional steel plate, so that the swallowing feeling of esophagus is prevented from being influenced.
