Description
Technical field
This utility model relates to a kind of cranio-maxillofacial folding synthetism fixing device, particularly relates to a kind of cranium jaw face locking-typed interior solid
Determine titanium plate.
Background technology
Along with the process of modernization, traffic and industrial accident increase year by year, and wound threatens people with being on the rise
Health, mandibular bone due to position highlight, fracture of mandible has become common clinical, frequently-occurring disease.Fracture of mandible is sometimes
Serious consequence can be caused, such as local pain, hemorrhage, numbness of lower lip and limitation of mouth opening, even swallow and the aspect such as breathing not
Good symptom.The most well treating in early days, treatment at a specified future date becomes more difficult, makes patient bring lifelong functional disability.
The Therapeutic Method used for fracture of mandible the most both at home and abroad mainly has Arch bar splint ligation intermaxillary traction and adopts
With miniature steel plate or compression plating two kinds.
Wherein, use the Therapeutic Method of Arch bar splint ligation intermaxillary traction, its fixing between jaw limit patient
Mouthful, after not only making operation in patients, occlusion receives restriction, also limit the training of the functional restoration after fracture simultaneously, affects fracture
Healing, increases the misery of patient.
The mode of employing miniature steel plate or compression plating is a kind of method of preferable treatment fracture of mandible, at present
The structure of miniature steel plate includes a steel matrix, and on steel matrix, interval has multiple fixing aperture, by this steel plate base during use
Body is erected between two mandibular bone of fracture, then fixes with mandibular bone through two or more fixing apertures with special screw,
The mandibular bone of fracture miniature steel plate fixing under gradually heal.
Chinese utility model patent " maxillofacial bone such as Patent No. CN91203346.0 (notification number is CN2091138Y)
Folding uses miniature steel plate holder ", and the China of Application No. CN201110071413.5 (Publication No. CN102688085A)
Patent of invention " locking compress bone-knitting device and use thereof " all discloses such a miniature steel plate.
Existing miniature steel plate structure has following defects that owing to miniature steel plate compression aspect is identical, and pressurization dynamics is inadequate,
Make can not be at the anatomical reduction of mandibular bone steady state, cause the fixing strength of existing miniature steel plate to be not enough to resist nozzle
The pressure chewed, causes fracture end to sink and rotation displacement, fixing, the healing of impact fracture and the recovery of normal occlusion, and this
Class minitype plate is all surface plate, large-area contacts with cranio-maxillofacial, is easily caused cranio-maxillofacial downright bad.
Utility model content
Technical problem to be solved in the utility model is to provide one can prevent cranium jaw face for above-mentioned prior art
Osteonecrosis also can realize Bidirectional-pressure and lock the locking-typed titanium plate for internal fixation in cranium jaw face settled at one go.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is: the locking-typed interior fixing titanium in a kind of cranium jaw face
Plate.The locking-typed titanium plate for internal fixation in described cranium jaw face, comprises the substrate in strip, and substrate has multiple interval along its length and sets
The long lumbar hole put, the long axis direction of described long lumbar hole is consistent with the length direction of substrate, and the side of long lumbar hole is pressurization hole, another
Side is screwed hole, and the hole wall in pressurization hole is vertically arranged, and the hole wall of screwed hole the most gradually inclines towards the center position of long lumbar hole
Tiltedly；It is characterized in that: described long lumbar hole is divided into two groups of left and right, and often group is respectively arranged with multiple described long lumbar hole, wherein first group leader's waist
Pressurization hole in hole is positioned at left side, and screwed hole is positioned at right side；Pressurization hole in the long lumbar hole of second group is positioned at right side, screwed hole position
In left side.Use screw by the screwed hole in long lumbar hole carry out pressurization fix, the compression aspect that left and right is two groups in opposite directions, both sides jaw
Bone photo is drawn close mutually, and sutura diminishes, and is beneficial to healing.
As improvement, the upper surface of described substrate offers multiple upper groove, and the lower surface of substrate offers multiple recessed
Groove, each upper groove and low groove are correspondingly arranged up and down.Base lower surface is fitted with jawbone, offers low groove and can prevent jawbone
Downright bad.The molding offering beneficially substrate of upper groove.
Improving, between adjacent two long lumbar holes, junction is equipped with described upper groove and low groove again.By upper groove and under
Groove is arranged between long lumbar hole, will not reduce the intensity of substrate, nor can affect the fixing pressurization of screw.Arrange multiple
Low groove can preferably prevent jawbone downright bad.
Improving, it is big that described low groove offers depth ratio upper groove again.Offer bigger degree of depth low groove, can preferably prevent
The head necrosis caused because titanium plate large area solid in cranium jaw face pushes down bone, in the upper groove of the less degree of depth is conducive to cranium jaw face
Gu the manufacture molding of titanium plate, offer the upper groove of the less degree of depth simultaneously, make foreign body sensation diminish, improve the comfort of user.
Improving, described upper groove and low groove are arc groove again.The groove design of circular arc type can reduce jawbone and week
Enclose the stimulation of tissue, contribute to the healing of wound.
Improving, the number of the long lumbar hole of the described first group long lumbar hole number with second group is identical again.Left and right same number
The setting of long lumbar hole makes left and right pressurization dynamics identical, is prevented effectively from fracture end and sinks and rotation displacement.
Compared with prior art, the utility model has the advantage of: titanium plate is provided with long lumbar hole, side is pressurization hole, another
Side is screwed hole, and pressurization hole is the initiating terminal of pressurization, and clearing end crosses screwed hole centrage, can be accurate with screw thread after making pressurization complete
Cooperation, it is achieved pressurize and locking settle at one go.Carry out adding pressing solidly in using the screw screwed hole in two groups of long lumbar holes respectively
Fixed, while constant pressurization dynamics is provided, make compression aspect in opposite directions, both sides jawbone is mutually drawn close, and sutura diminishes, and is beneficial to more
Close.After improved, described cranium jaw face locking-typed titanium plate for internal fixation upper and lower surface is provided with groove, and cranio-maxillofacial can be prevented downright bad,
Arrive more preferable healing effect.
