Description
Technical field
This utility model relates to the external support of a kind of orthopaedics, belongs to medical instruments field.
Background technology
After extremity fracture, need to be fixed skeleton, help it recover as soon as possible and heal, Orthopaedic external fixator is one of medical apparatus and instruments conventional on Orthopedic Clinical.
In prior art, when fracture, general Orthopedic splint or the medical gypsum of adopting is fixed, traditional Orthopedic splint or medical gypsum can only simply be located the skeleton of fracture, play the stable effect of fracture site that ensures, in the process of bone healing, because Orthopedic splint or medical gypsum can not be removed, can not carry out direct drug injection to skeletal sites, generally can only adopt innerlich anwenden thing to carry out auxiliary treatment, and Gypsum Fibrosum easily makes moist, weight is large, affects blood circulation, breathability is poor, after use, easily pollutes.
Fracture takes place frequently now, if adopt operative treatment, need under epidural or lumbar anesthesia (half body anesthesia), carry out, because operative incision is large, on surface of bone, peel off cut-out muscle, hemorrhage many, risk is high, needs to transfuse blood in operation simultaneously, also needs second operation to take out implant.Also often adopt traction and Gypsum Fibrosum fixing outward, though without percutaneous incision meat tissue, go out insufficiency of blood, postoperative patient needs long-term bed, and patient is greatly painful, nurses very inconveniently, easily produces complication.Common exterior fixation bracket, this type of technology is all used steinman pin.But should be poor for the restraining forces of fracture, effectively stable fracture position, because pin position disperses, far away apart from fracture end, significantly limit muscular movement, patient's self preservation activity is reduced, joint motion reduces, and causes ankylosis.
Mostly be provided with a connecting rod at the existing traditional orthopedics external-use fixed support causing because of wound, be connected to shank fixation clamp on connecting rod, be connected to the folder pin piece on shank fixation clamp, locking pin is clamped on pin piece.
Shortcoming below general existence of fixed support of said structure: the folder fixing setting in pin piece position, make locking pin position fixed thereon single, can not be fixed the fixing skeleton of needs flexibly, and when patient's skeleton starts healing, cannot carry out suitable adjusting, and the fixed support having is Gypsum Fibrosum series products, easily make moist, airtight, not blood circulation promoting, the large orthopaedics growth that affects patient of weight, is also unfavorable for that in the time that convalescence removes examination in hospital doctor checks, uses later and can not use by secondary.
Summary of the invention
goal of the invention: the purpose of this utility model is just to provide a kind of length, the equal scalable of angle, the more stable external support of fixing orthopaedics.
technical scheme: for achieving the above object, this utility model has been taked following technical scheme:
The external support of a kind of orthopaedics, comprise connecting rod, folder pin piece holder, folder pin piece, the first universal joint that the two ends of described connecting rod are connected with slidably and rotate, described the first universal joint end is connected with expansion link, the other end of described expansion link is connected with the second universal joint, described the first universal joint, what the second universal joint slidably also rotated is set on described expansion link, the other end of described the second universal joint is connected with described folder pin piece holder, what described folder pin piece holder rotated is sheathed in described the second universal joint, described folder pin piece is located on described folder pin piece holder, on described connecting rod, be also provided with pressure regulator, on described connecting rod and expansion link, be all respectively equipped with locking device.Between adjusting rod and folder pin piece holder, be provided with universal joint, on the installation of folder pin piece rotation and folder pin piece holder, the angle of pressing from both sides pin piece can be regulated flexibly, between two universal joints, be provided with expansion link, make the longitudinal length scalable of support, the pressure regulator being provided with, can regulate support to suitable pressure, can also make the isostasy at the each position of support simultaneously, the comfortableness of support is increased, what the locking device being provided with made that support can be more stable fixes.
The two ends of described connecting rod are provided with the adjusting rod of adjustable in length, described the first universal joint slidably and turning set be located on described adjusting rod.The setting of adjusting rod, can regulate the horizontal length of support flexibly.
Described pressure regulator is located at the middle part of described connecting rod.Middle part is located substantially on the center of gravity line of support, makes the adjusting of pressure more balanced.
Described locking device is located between described connecting rod and adjusting rod, and between expansion link and the first universal joint, the second universal joint.At each length adjustment position, locking device is installed, makes support be difficult for sliding, stability increases.
Described in each, the material of parts is rustless steel, aluminium alloy or titanium alloy.This type of material is for Gypsum Fibrosum, light, be difficult for polluting, can be recycled.
beneficial effect: the following advantage that the utlity model has that adopts technique scheme:
1, this utility model is simple in structure, and for technical scheme in the past, orthopaedics of the present utility model increases with external supporting structure motility, horizontal and longitudinal all scalable of length, and the angle of folder pin piece can regulate flexibly;
2, this utility model is provided with pressure regulator, makes the equilibrium of this utility model integral pressure, and comfortableness strengthens;
3, this utility model is provided with locking device, makes the stability of this utility model entirety more firm;
4, this utility model has been avoided practical gypsum material, make this utility model entirety lighter, be difficult for polluting, can be recycled;
5, this utility model entirety scalable, can better coordinate patient's later stage rehabilitation, reduces patient's slight illness, alleviates medical personnel's working strength.
