Abstract
The utility model provides an external use medical appliance which is used for the orthopedic fields of a department of orthopedics, such as the lengthening of limbs, orthopedics, fracture fixation, etc. The appliance is a long and rectangular metal bracket which is composed of metal screw nails, drift bolt plates, screw rods, etc., which are formed by connecting and can be mechanically regulated in each direction. When the utility model is applied, the bracket is fixed onto affected limbs in a skeleton manner of the drift bolts of extracorporeal minimally invasiveness, and the utility model realizes multiple functions, such as lengthening, shortening (pressurization), orthopedics, fixation, etc., and functions to therapeutic positions by artificially and mechanically regulating relevant apparatuses on the bracket. The utility model is an ideal external fixation therapeutic appliance in the orthopaedic fields of the bone fracture and the orthopedics, such as limb lengthening (the therapy of increase of short stature, the unequal length of the limbs, and limb shortening), limb orthopedics (the remedy of deformation of 'O'-shaped legs, 'X'-shaped legs, etc.), the fixation of limb bone fracture, bone defect, nonunion, etc.
Description
Affiliated technical field
This utility model relates to a kind of orthopaedics external fixation therapeutic apparatuss such as limb lengthening, orthopedic, fracture fixation that are used for.
Background technology
General orthopaedics (orthopedics), treatment fracture, osteopathia, normal surgical incision and the steel plate of adopting such as cacomelia, fixing or Gypsum Fibrosum such as intramedullary needle, the treatment of clamping plate external fixation.The former damages greatly, and complication is many, and needs second operation to take out inside-fixture; The latter is fixing not firm, and curative effect is unreliable, easily produces complication such as distortion or disunion.The two not only affects the treatment, and has limited the therapeutic domain of some bone injury disease.In order to address these problems, external the threading a needle of percutaneous (nail) exterior fixation bracket of metal frame for movement has appearred adopting, as the external fixator of set a broken bone disease.Propose application external fixator set a broken bone disease as Chinese patent ZL922271631 and improved curative effect, but a kind of as the orthopaedics external fixator, because there is significant difference in its technical scheme (structural design etc.), determined existing orthopaedics external fixator to there are differences and deficiency in the first-class all many-sides of character, function, curative effect and scope.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, light, can strongly fix, can realize flexible, reliable multidimensional mechanical adjustment again, have prolongation, orthopedic, fixing, pressurization function apparatuses such as (shortening), limb lengthening, limbs are orthopedic, limb fracture fixing and the treatment of some osteopathia provides a kind of ideal effective Multifunction orthopaedics external fixation therapeutic apparatus in order to be undertaken by less invasive techniques.
The scheme that its technical problem that solves this utility model adopts is: constitute a track with a screw rod, a slide bar, its two ends have been connected to form a long square type support with holder and mobile seat respectively, again respectively at a drift bolt plate respectively is installed on holder and the slide, the drift bolt plate is provided with screw, screw is penetrated on the skeleton of limbs by the drift bolt hole on the drift bolt plate, to realize fixation limbs.Can realize moving seat by rotary screw and produce elongation and shorten function, prolong or pressurization thereby make to produce between bone stump along slide bar.Because the side at holder and slide has respectively designed plate washer (the seat back of the body) structure that raises up.And on plate washer (seat the back of the body), the adjusting bolt has been installed, and by rotating this bolt, can realize the drift bolt plate is carried out adjusting on vertical axis (Y-axis) direction, thus the interior or valgus deformity that realizes correcting limbs; Because two pieces of set bolts and four pieces of adjusting bolts are set in the center on the drift bolt plate, rotate simultaneously and adjust bolt and can realize universal adjustment by loosening set bolt the similar spherical joint of drift bolt plate, thereby the displacement on the directions such as forward and backward and rotation of rectification fracture site, adjust and penetrated the length of bone inner bolt on the drift bolt plate, can realize the adjustment of fracture end lateral displacement.
The beneficial effects of the utility model are: owing to adopted one-sided formula exterior fixation bracket structure, and by strong stable fixing, easy, flexible, safe and reliable multidimensional mechanical adjustment, realized the prolongation to the limbs therapentic part, orthopedic, fixing, pressurization multiple functions such as (shortening), and simple in structure, body constitution is light, easy operating, curative effect reliably, multi-use, therapeutic domain be wide.Not only can be used for Wicresoft's limb lengthening (treat of short and small stature, limb shortening is not isometric), limbs orthopedic (cacomelia), limb fracture (fixing), and be multiple bone injury disease (, bone does not connect damaged, osteomyelitis etc.) the ideal external fixation therapeutic apparatus of postoperative as bone.
