Description
This utility model relates to medical apparatus and instruments, particularly a kind of split adjustable lower jawbone external immobilizer for fracture restitution.
For the patient of fracture of mandible, conventional Therapeutic Method be adopt that single jaw is fixed, method such as fixing between fixing and bone between jaw, these methods all have tangible deficiency.As the single jaw of Arch bar splint or tinsel ligation fixedly is to belong to a kind of fixing means, and because of fixedly strength is little, stability maintenance is poor, and the simple fracture that generally is only applicable to not have obvious displacement is fixed or cooperated other fixing meanss to use together.Fixation between jaw also belongs to one of external fixation.Because of last lower jaw is fixed together, wounded's limitation of mouth opening, functions such as influence feed, language be unfavorable for the oral cavity cleaning health, and to edentulous jaw, dental pattern week, scorching tooth body were loosening, and the jackknifing of popularity tooth trauma lacks the arrow person, should not adopt this method.Fixedly belong to internal fixation method between bone, need the surgical incision soft tissue, appear fracture site, increased patient's local wound and used steel wire to make fastening's less stable between bone.Inner matters such as steel plate spiral shell pin are the person fixedly, have easily to be excluded, and the anxiety that gets loose, operation easier is higher, enough soft tissue flap coverages need be arranged during application or need second operation to take out inner matter, and forbid in local infection, suppuration, opening fracture.
The purpose of this utility model is in order to solve above-mentioned existing in prior technology problem, and a kind of split adjustable lower jawbone external immobilizer for fracture restitution is proposed, this holder is by respectively wearing 1～2 piece of bone garden pin 3 external fixation that resets in mandibular bone lower edge fracture end both sides through skin, in the hope of the occluding relation that obtains to recover good, reduce operation wound and influence the unfavorable factor of union of fracture, shorten or exempt the set time between jaw, to prevent the generation of bad complication.
This utility model mainly is connected curved bar 1, bone garden pin 3 by one with similar arciform of mandibular bone major axis shape, be enclosed within several slide blocks 2, the afterburning folder on the curved bar 1 and regulate spanner and constitute.Wherein, fixing between slide block 2 and the curved bar 1 by screw 10, head at slide block 2 is with bolt folder 5, purl bolt 7 is contained in the hole of bolt folder 5, have the hole 9 of threading a needle in the side of purl bolt 7, bone garden pin 3 is contained in this hole 9 of threading a needle, and it is fixedly clamped by pin nut 8 and the bolt folder 5 of deciding that is positioned on the purl bolt 7, and one 4 of purl bolt 7 is polygon.
During use, at first the patient is carried out local anesthesia, about distance fracture of mandible end both sides 1cm, respectively wear 1 piece of bone garden pin 3 then in the lower jaw lower edge, look fracture site and the fracture misalignment can respectively wear 1 piece of auxiliary bone fixation garden pin 3 in mandibular bone broken ends of fractured bone one or both sides again, afterwards, the afterbody of exposed body surface bone garden pin 3 is penetrated respectively in the hole 9 of threading a needle in the purl bolt 7, adjust the position of curved bar 1, tighten and decide pin nut 8 bone garden pin 3 is fixed on the purl bolt 7, be enclosed within purl bolt 7 polygonal with the sleeve pipe 16 of regulating Wrench head, regulate the position of purl bolt 7 and bolt folder 5, drive bone garden pin 3 and reverse displacement to correct fracture, fastening nut 6 is with bolt folder 5, and purl bolt 7 is fixed on the slide block 2.Two arc card arms 13 with the reinforcing folder are stuck on the cervical region draw-in groove of adjacent two slide blocks 2 in fracture two ends, tighten the adjusting nut 15 on the afterburning folder, draw two card arms 13 through screw rod 14, promote two slide blocks 2 and move, drive bone garden pin 3 and make fracture end obtain axial compressive force to relative direction.Tighten screw 10 at last, slide block 2 is fixed on the curved bar 1, the fracture of mandible end just is fixed like this, keeps geometry indeformable.Also can adjust at any time simultaneously fracture para-position situation.Treat that fracture reaches clinical healing and can remove this utility model.For complexity or bone damaged mandibular fracture is arranged, can cooperate a mouthful interior Arch bar splint, method auxiliary treatment such as short-term intermaxillary traction and mouthful outer suspension, elastic traction.
The utlity model has following advantage.
1, simple in structure, be convenient to operation, be easy to grasp, in light weight.
2, do not need surgical incision local soft tissue and periosteum, only need respectively wear 1-2 piece of bone garden pin respectively at fracture folding end, assembling is fast, and is easy to adjust, damage for a short time, and patient is painful to be lacked, and the position concealed of threading a needle obviously influences nothing attractive in appearance.
3, purl bolt, bolt folder and slide block be flexible within the specific limits, and reset response is reliable.
4, can avoid doing fixing between jaw or obviously shortening the set time between jaw, make the patient exercise oral cavity function in early days, safeguard oral hygiene, the prevention secondary infection can prevent because of passive fasting causes stomach discomfort malnutrition, weight loss simultaneously.
5, open the jaw fixation for treatment in early days, and keeping fracture site to put up under the geometrically stable system flexible fastening situation through bone garden pin and external fixation, make fracture end obtain suitable stress stimulation, safeguard effective activity of muscles of mastication and temporomandibular joint, can promote union of fracture and mouth opening to recover, shorten rehabilitation duration greatly.
6, relation recovers reliable, dehisces, masticatory function recovers fast.Can be used for open infectious fracture, can carry out the part simultaneously during the treatment and change dressings.Also can be used for being not suitable for using the case of fixing between Arch bar splint ligation jaw (as edentulous jaw, the tooth body is extensively loosening, infects disappearance etc.), can be used as a mouthful outer auxiliary hitch.
Followingly specify this utility model with reference to accompanying drawing.
Fig. 1 is a front view of the present utility model.
Fig. 2 is an A-A cutaway view among Fig. 1.
Fig. 3 is the front view of afterburning folder.
