Abstract
The utility model discloses the traction apparatus of a kind of upper jaw bone bone load, comprise fixed support, described fixed support is provided with cross bar, cross bar lateral symmetry is provided with Flexible Connector, described Flexible Connector is respectively connected with a hook, described hook comprises fixation hook and is arranged on the draft arm at fixation hook two ends, described fixation hook and draft arm form the L-shaped three-dimensional integrated formula structure of plane, described pintle hook construction and the matching of model of human maxilla structure phase, during installation, the draft arm of hook one end passes from nasal cavity, the draft arm of its other end passes from the oral cavity of upper jaw bone.In this utility model, pintle hook construction complete matching upper jaw bone partial 3 d form, fits with upper jaw bone close structure, avoids the inconvenience exposing to skin surface and bring, and makes whole upper jaw bone distraction procedure safety and reliability effective; There is small volume, operation is inserted conveniently, Wicresoft and the advantages such as load mode safety and stability.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of upper jaw bone bone load traction apparatus of correcting for jaw facial deformity.
Background technology
Mid facial hypoplasia is a kind of common jaw facial deformity, and is secondary to long-QT syndrome patient more, impacts to the jaw surface function of patient and profile.Because this deformity occurs comparatively early, usually grow Psychology of childhood patients and cause harmful effect, correction deformity is conducive to promoting that Psychology of childhood patients is grown as early as possible.Usually adopt at present and treat through seam traction upper jaw bone technology, through seam traction upper jaw bone technology, there is Wicresoft, simple to operate, risk is little, be applicable to the advantages such as trophophase infant, be successfully applied to clinical.
Apply pull strength through seam traction upper jaw bone technology mainly through external traction apparatus to act on upper jaw bone to realize.Upper jaw bone traction apparatus was generally mounted in maxillary dentition in the past, it leads load and acts on maxillary dentition, and this device of the incomplete infant of denture is often difficult to effectively fixing, and easily causes upper jaw bone counter-rotating and the overall parallel therapeutic effect moved forward cannot be reached.The bone bearing type traction apparatus adopted at present usually because of hard point be upper jaw bone rersistant center, thus avoid above-mentioned shortcoming, but pintle hook construction does not fit with local upper jaw bone structure in the traction apparatus of existing bone load, insert to operation and bring certain difficulty, hook after installation has part to expose, not only affect attractive in appearance, and exposed skin part easy damaged skin, bring certain impact to the life of patient.
Utility model content
The purpose of this utility model is to solve the problems of the technologies described above, and provides the hommization more of a kind of structure, and operation is inserted conveniently, for the upper jaw bone bone load traction apparatus that jaw facial deformity is corrected.
For solving the problems of the technologies described above, this utility model have employed the traction apparatus of a kind of upper jaw bone bone load, comprise fixed support, described fixed support is provided with cross bar, cross bar lateral symmetry is provided with Flexible Connector, described Flexible Connector is respectively connected with a hook, described hook comprises fixation hook and is arranged on the draft arm at fixation hook two ends, described fixation hook and draft arm form the L-shaped three-dimensional integrated formula structure of plane, described pintle hook construction and the matching of model of human maxilla structure phase, during installation, the draft arm of hook one end passes from nasal cavity, the draft arm of its other end passes from the buccal side of upper jaw bone.
Described draft arm front end is provided with connecting hole.
Described hook is made up of titanium alloy material.
Pintle hook construction in this utility model complete matching upper jaw bone partial 3 d form, its small volume, only draft arm ends exposed is connected in mouth and nose chamber with external fixed support, avoids the inconvenience exposing to skin surface and bring, and makes whole upper jaw bone distraction procedure safety and reliability effective; Having operation inserts conveniently, Wicresoft and the advantages such as load mode safety and stability.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is pintle hook construction schematic diagram in this utility model.
In figure: 1, fixed support; 2, cross bar; 3, Flexible Connector; 4, hook; 5, fixation hook; 6, draft arm; 7, connecting hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, to this utility model concrete structure, feature and using method thereof, be described in detail as follows.
Upper jaw bone bone load traction apparatus as illustrated in fig. 1 and 2, comprise fixed support 1, described fixed support 1 is provided with cross bar 2, cross bar 2 lateral symmetry is provided with Flexible Connector 3, described Flexible Connector 3 is respectively connected with a hook 4, described hook 4 comprises fixation hook 5 and is arranged on the draft arm 6 at fixation hook 5 two ends, described fixation hook 5 and draft arm 6 form the L-shaped three-dimensional integrated formula structure of plane, described hook 5 structure and the matching of model of human maxilla structure phase, during installation, the draft arm 6 of hook 5 one end passes from nasal cavity, the draft arm 6 of its other end passes from the buccal side of upper jaw bone, described draft arm 6 front end is provided with connecting hole 7, and Flexible Connector one end 3 is connected with the connecting hole 7 on the draft arm passed from nasal cavity.
Hook 4 described in this utility model adopts medical titanium alloy material to make.
When installing hook, above vestibule of mouth ditch canine tooth, cut out 2cm length walk crosswise otch, cut and expose upper jaw bone antetheca and canine tooth pillar, 5mm, the distance oblique punching in 1cm place, apertura piriformis edge above canine tooth root of the tooth, upper jaw bone medial wall is penetrated through upper jaw bone antetheca diagonal, passed in this oblique hole hole by hook, the draft arm end via intranasal application of hook one end passes, and the draft arm of the hook other end is then retained in buccal side; Then hook is fixedly connected on the Flexible Connector on fixed support by the connecting hole on the draft arm that passes from nasal cavity, finally fixed support is fixedly mounted on human skull.The hook of this traction apparatus fixedly leans against on upper jaw bone by being arranged on intraoral draft arm, and upper jaw bone, thus outwards to be drawn for hook provides an outside pull strength by connected flexible member by the other end.
This utility model structure complete matching upper jaw bone partial 3 d form, its small volume, only draft arm ends exposed is connected in mouth and nose chamber with external fixed support, avoids the inconvenience exposing to skin surface and bring, and makes whole upper jaw bone distraction procedure safety and reliability effective; Having operation inserts conveniently, Wicresoft and the advantages such as load mode safety and stability.
Description of the present utility model and accompanying drawing are considered to illustrative and nonrestrictive; on the basis of technical scheme disclosed in this utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some of them technical characteristic to replace and distortion, these are replaced and are out of shape all in protection domain of the present utility model.
