Utility model content
This utility model object is to provide a kind of lamina of axis to follow closely guider, put nail employing traditional approach to solve vertebral plate in prior art or put nail by rule of thumb, easily insert intraspinal tube Spinal Cord, or be difficult to effectively obtain satisfied fixing, not only increase operation risk, more can cause the technical matters of adverse effect to patient.
The technical solution of the utility model is achieved in that
A kind of lamina of axis nail guider, comprise fixed mount main body and pilot sleeve main body, described fixed mount main body comprises arc frame, described arc frame comprises head end and tail end, wherein, in the middle part of arc frame, inclined tail end is provided with the first locking piece, the head end of described arc frame is provided with the second locking piece, described pilot sleeve main body comprises hollow guiding cylinder and the vertebral plate nail pilot sleeve for putting nail, vertebral plate nail pilot sleeve can insert hollow guiding cylinder, described hollow guiding cylinder is located at the tail end of arc frame, and the inside extended line of described hollow guiding cylinder is through the arc core of arc frame.
Preferably, described first locking piece comprises for Universal lock locking member, described Universal lock locking member comprises long bar stock and universal spheroid, described universal spheroid embeds the position of tail end partially in the middle part of arc frame and opposing arcuate frame universal rotational, described long bar stock passes universal spheroid and is fixedly connected with it, and stock shape handle end is provided with drill bit.
Preferably, described second locking piece is scalable hold-down screw, and the axially-extending line of described scalable hold-down screw passes the arc core of arc frame.
Preferably, described vertebral plate nail pilot sleeve is provided with push and pull bar.
Compared with prior art, this utility model has following beneficial effect:
Lamina of axis nail guider of the present utility model, be provided with fixed mount main body and pilot sleeve main body, fixed mount main body adopts Universal lock locking member, fixed mount main body is made to regulate correct position by Universal lock locking member and fix, during positioning and guiding and guider sleeve conbined usage registration, allocation nail process can once complete, and can not cause damage to spinal cord, safe and reliable, reduce operation risk.
Accompanying drawing explanation
Fig. 1 is the structural representation of lamina of axis of the present utility model nail guider.
In figure: 100-arc frame, 101-head end, 102-tail end, 200-hollow guiding cylinder, 300-vertebral plate nail pilot sleeve, the long bar stock of 400-, the universal spheroid of 500-, 600-drill bit, the scalable hold-down screw of 700-, 800-push and pull bar.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.
Please refer to accompanying drawing 1, a kind of lamina of axis nail guider, comprise fixed mount main body and pilot sleeve main body, described fixed mount main body comprises arc frame 100, described arc frame 100 comprises head end 101 and tail end 102, wherein, in the middle part of arc frame 100, inclined tail end 102 is provided with the first locking piece, first locking piece can be fixed on C2 spinous process, the head end 101 of described arc frame 100 is provided with the second locking piece, second locking piece can be fixed on lamina of axis and articular process intersection, described pilot sleeve main body comprises hollow guiding cylinder 200 and the vertebral plate nail pilot sleeve 300 for putting nail, vertebral plate nail pilot sleeve 300 can insert hollow guiding cylinder 200, described hollow guiding cylinder 200 is located at the tail end 102 of arc frame 100, the inside extended line of described hollow guiding cylinder 200 is through the arc core of arc frame 100.
Described first locking piece comprises for Universal lock locking member, described Universal lock locking member comprises long bar stock 400 and universal spheroid 500, described universal spheroid 500 embeds the position of inclined tail end 102 in the middle part of arc frame 100 and opposing arcuate frame 100 universal rotational, described long bar stock 400 passes universal spheroid 500 and is fixedly connected with it, long bar stock 400 end is provided with drill bit 600, when needing adjustment Universal lock locking member fixed position, only slowly need promote long bar stock 400 makes universal spheroid 500 rotate along itself and arc frame 100 contact portion, wait to rotate to correct position, turning long bar stock 400 just makes drill bit 600 pierce suitable fastening points.
