Description
Technical field
This utility model is directly involved in medical field, particularly a kind of occipital plate and the surgical fixation system with this occipital plate.
Background technology
Spinal column is the high complexity system of bone and connective tissue, and this system is that health provides support and protects fragile spinal cord and nerve.Spinal column comprises a series of vertebral bodys that are stacked on another, and each vertebral body comprises the exterior section of the inside of relatively fragile spongy bone or core and relatively hard cortical bone.Intervertebral disc is between each vertebral body, and intervertebral disc cushions and suppresses to be applied to epispinal compression stress.After the canalis spinalis that comprises spinal cord is positioned at vertebral body.
Permitted eurypalynous disorder of the vertebral column, other diseases that comprise skoliosis (the abnormal lateral bending of spinal column), too much kyphosis (the abnormal bend forward of spinal column), too much lordosis (spinal column is bending extremely backward), spondylolisthesis (spondy lothesis) (the forward displacement of a vertebra on another vertebra) and caused by abnormal, disease or wound, such as ruptured intervertebral disc or intervertebral disk hernia, degenerative disc disease, vertebral fracture, etc.Conventionally experienced extremely and unable misery by the patient of this type of disease, and the function of nervous system of decay.
Be often referred to be used as the fixing surgical technic of spine surgical implant two or more vertebral bodys of spinal column are merged and/or two or more vertebral bodys of spinal fixation mechanically.Can fixedly change adjacent vertebral alignment relative to each other with spine equally, to change the entirety alignment of spinal column.Effectively use this type of technology to treat disease described above, and in most of the cases alleviated misery.
-kind of spine technique for fixing comprises using and is often referred to the orthopedic firm bar of making spinal rod and fixes spinal column, and this orthopedic firm bar is roughly parallel to spinal column and extends.By exposing spine rear side, and bone screw is fastened to basivertebral pedicle of vertebral arch realizes this technology.Each vertebra is roughly placed two pedicle screws (pedicle screw) and the pedicle screw anchor point as spinal rod.With the clamping or the connection element that are suitable for holding through the spinal rod due to this, spinal rod is connected to pedicle screw subsequently.The alignment impact of spinal rod forces spinal column to meet the shape of more expecting.In some cases, the bending spinal rod of energy realizes the desired curvature of spinal column.
There is the relevant shortcoming of many and existing spine fixing device.For example, in the time connection element must being rotated to extreme angles, for fixing spinal rod, the bone fixation apparatus of many prior aries is not best.Use this equipment, the pivoting action of anchor portion is limited in the angle (from vertical survey) that is roughly no more than 40 ° in any direction.When because the curvature of spinal column and hold screw adjacent pedicle of vertebral arch different azimuth and when connection element is not lined up each other, attempting to insert aspect spine fixing device, surgeon runs into sizable difficulty.As a result, conventionally must be in multiple plane inner bending spinal rod, to bar is passed through to contiguous connection element.This may weaken potentially overall assembling and cause the operation of long period and the complexity of larger probability.In the time of application occipital plate (occipital plate), can produce the further problem being caused by the natural curvature of patient's spine.
In view of this, those skilled in the art, for the problems referred to above, provide a kind of occipital plate.
Summary of the invention

Preferably, the cross section of described occipital plate body is stepped.
Preferably, the lower surface of described occipital plate body is provided with some bending grooves.
Preferably, described bending groove is perpendicular to the length direction of described occipital plate body.
Preferably, described bending groove is positioned at the below of the ladder end face of described occipital plate body.
Preferably, the excellent sidewall of described lock is semicircle annular.
Preferably, described locating slot is semicircle.
Preferably, the locating slot of the excellent sidewall of described lock is positioned at the below of described female thread.
This utility model also provides a kind of surgical fixation system, comprises above-mentioned occipital plate, also comprises screw, locknut and implants rod;
The described implantation rod of lock rod sidewall clamping of described occipital plate, the excellent both sides of described implantation are respectively equipped with location lug, and described location lug engages respectively in the locating slot of the excellent sidewall of described lock;
Described locknut screws togather the female thread of the excellent sidewall of described lock, and described locknut compresses described implantation rod in described occipital plate body;
Described screw, is bolted in described nail hole.
Preferably, described location lug is semicircle.
Owing to having used above technology, occipital plate of the present utility model and surgical fixation system meet the feature of human body skull anatomy, and incisura is low, can bending, the surface of bone of can fitting completely, anti-spin stabilization, and two layout regulations of being independently more convenient for, install flexibly position.
Further illustrate this utility model below in conjunction with drawings and Examples.
