Abstract
The utility model discloses a kind of artificial dentata, comprise dentata body, described dentata body comprise can with the inferior articular surface of lateral mass of atlas formed contact with the bizet supported with can form with soleplate on third cervical vertebra the body contacting and support, described bizet forms the shoulder stretched out to the left and right sides above described body, the end face of described bizet forms the cambered surface of upwards being swelled gradually to centre by shoulder, the inside of described dentata body forms cavity, be provided with micropore net grid support in described cavity, described cavity forms multiple window on the surface of dentata body.After dentata body inserts Cranial defect region, upper and lower two ends can be formed dissect laminating, its support and reconstruction of stability good, avoid loosening and failure of Post operation prosthese, easily fixing, form fit is good, postoperative Unstable internal fixation rate is low, and fusion rate is high, can meet complicated operation needs.
Description
Technical field
This utility model is used for technical field of medical instruments, particularly relates to a kind of artificial dentata.
Background technology
Involve the usually Atlantoaxial important feature of heavy damage such as the tuberculosis of upper cervical spine, tumor, and oppress spinal cord, and then cause the serious consequence of paralysis.This kind of patients need operative excises pathological changes, and rebuilds the structure destroyed and fix, and to maintain the structural integrity of cranio-cervical junction and to stablize, safeguards normal physiological function.
Because atlas and axis is positioned at cranio-cervical junction, its anatomical structure is special, and position exists deeply, has important nerve and blood vessel around, and its excision and reconstruction operations are all difficult points of spinal surgery.Be mainly reflected in: 1. operation appears more difficult, excise atlas and axis focus, generally need to adopt Transoral, if extent of disease is larger, or the scope that reconstruction is fixed is large, then may need the operative approach adopting the wounds such as mandibular bone of riving larger, and this operation appears and usually needs the doctor of the department of stomatology to coordinate.2. operation technique has a big risk, and Atlantoaxial intraspinal tube accommodates upper cervical spinal cord and oblongata, and removal of lesions needs superb surgical technic, careless slightly, and damage oblongata has paralysis and dead danger.Also have the important blood vessels such as vertebral artery around atlas and axis, once damage, the consequence of Cerebellar Infarction or death can be caused.3., after lesion resection, spine structure rebuilds difficulty.The internal fixation of spine equipment used clinically at present has the pedicle screw-rod of the way of escape, anterior plate fixation etc.But these fixation devices design mainly for Cervical vertebra, common cervical vertebra titanium plate is not suitable for atlas and axis and fixes.Common titanium net is unanimous between the higher and lower levels cylindrical, also cannot meet the reconstruction needs of the complicated anatomical shape of atlas and axis.Although some scholars improve implants such as titanium nets both at home and abroad, and the reconstruction be applied to after atlas and axis excision, but the implant of improvement is applied to the operation of this position, still there is fixing difficulty, form fit is poor, postoperative Unstable internal fixation rate is high, and the defects such as fusion rate is low, are difficult to really meet complicated operation needs.
Utility model content
For solving the problem, this utility model provides a kind of easily fixing, and form fit is good, and postoperative Unstable internal fixation rate is low, and fusion rate is high, can meet the artificial dentata of complicated operation needs.
This utility model solves the technical scheme that its technical problem adopts: a kind of artificial dentata, comprise dentata body, described dentata body comprise can with the inferior articular surface of lateral mass of atlas formed contact with the bizet supported with can form with soleplate on third cervical vertebra the body contacting and support, described bizet is formed left above described body, the shoulder that right both sides are stretched out, the end face of described bizet forms the cambered surface of upwards being swelled gradually to centre by shoulder, the inside of described dentata body forms cavity, micropore net grid support is provided with in described cavity, described cavity forms multiple window on the surface of dentata body.
Be further used as the improvement of technical solutions of the utility model, described body is column.
Be further used as the improvement of technical solutions of the utility model, the bottom end face of described body is smooth, and ovalize.
Be further used as the improvement of technical solutions of the utility model, described bizet, body and micropore net grid support are print one-body molded that manufactures by 3D.
Be further used as the improvement of technical solutions of the utility model, described cavity all forms window on the front surface of described dentata body, rear surface, left surface, right surface, upper surface and lower surface.
The beneficial effects of the utility model: during this artificial dentata operation, select the artificial dentata of suitable types size, insert Cranial defect region, artificial dentata forms the cambered surface of upwards being swelled gradually to centre by shoulder at the end face of bizet, dentata body can be formed with the inferior articular surface of lateral mass of atlas by described cambered surface and contact and support, to be formed with soleplate on third cervical vertebra by the bottom surface of body and contact and support, upper and lower two ends are formed dissects laminating, its support and reconstruction of stability good, avoid loosening and failure of Post operation prosthese, easily fixing, form fit is good, postoperative Unstable internal fixation rate is low, fusion rate is high, complicated operation needs can be met.
