Abstract
The utility model discloses an external fixing frame elastic device for orthopaedic clinic application, consisting a cylinder casing, a slide shaft, an elastic device and a displaying device, wherein the slide shaft and the elastic device are arranged inside the cylinder casing, the displaying device is arranged outside the cylinder casing; the wall of the cylinder casing is provided with a slide shaft micro motion limitation bolt along the radial direction; a bottom cover of the cylinder casing is provided with an elastic device adjusting bolt; the elastic device can be made in a spring type or an elastic capsule type, the displaying device comprises a pressure displayer and a hydraulic pressure gauge; the elastic device can be matched with external fixed frames with different structural shapes, forming the elastic external fixed frame. When the fractured limbs and trunk are axially pressed, the elastic external fixed frame has 2mm of micro motion range, which makes the micro motion of the fractured ends and generates an interacting force, thereby stimulating the growth of the bone callus on the fractured end, avoiding the osteoporosis due to the stressing occlusion of the external fixed frame, speeding up the fracture heeling, reinforcing the bone intensity and effectively preventing the delayed heeling or the disunion of the fracture.
Description
Affiliated technical field
The utility model discloses a kind of externally fixing support elastic device of orthopaedics clinical practice.
Background technology
The orthopaedics therapy fracture needs to use external fixer sometimes, and existing various external fixers are though shape and structure is different, but all can't carry out fine motion regulates, lack the flexible adjustment device, easily produce stress shielding during application and form osteoporosis, refracture takes place behind the removal external fixer easily.Because fracture end can not fine motion, no Pressure stimulation, callus generates slow, and growing amount is few, and speed of fracture union is slow.
Summary of the invention
The purpose of this utility model just is to remedy the deficiency that current use external fixer treatment fracture exists, adopt a kind of elasticity fine motion adjusting device externally fixing support elastic device, can effectively prevent to produce stress shielding, avoid forming osteoporosis, and can stimulate the fracture end callus to generate accelerating bone healing.
Externally fixing support elastic device is sliding axle, the elastic device by cylinder barrel and cylinder barrel inside, and outside compositions such as display device.The cylinder barrel wall radially is provided with sliding axle fine motion stop screw, and the stop screw head end is cylindric, and stop screw is fashionable from outer buttons, can prevent that sliding axle from moving down, during back-out, but sliding axle fine motion under responsive to axial force move down, displacement generally is controlled at 2 millimeters.The cylinder barrel bottom is provided with the elastic device pressure regulating screw, when pressure regulating screw screws in or screws out from the cylinder barrel bottom, can adjust the pressure of elastic device.
Cylinder barrel comprises barrel and upper and lower covers, and barrel top and sliding axle cooperation place internal diameter are greater than the bottom internal diameter, and the radially set stop screw centrage of barrel is higher than 1 millimeter on barrel internal diameter step, and the lower cover of cylinder barrel bottom is established the elastic device pressure regulating screw.
The display device of the elastic device of cylinder barrel inside and cylinder barrel outside can be made multi-form.
Elastic device is generally made spring or elastic capsule formula.Spring comprises spring, pressure transducer and lower bottom base, and spring places between sliding axle and the pressure transducer, and lower bottom base is located by the adjustment of lower cover pressure regulating screw; The elastic capsule formula comprises the bullet shape rubber bag tank and the bottom rubber bag tank base of internal-filling liquid pressure oil, and the gum elastic capsule places between sliding axle and the bottom rubber bag tank base, and bottom rubber bag tank base is also located by the adjustment of lower cover pressure regulating screw.
Pressure display unit or hydraulic gage are generally adopted in display device.The pressure transducer by lead connection elastic device of pressure display unit is adopted in display device; That adopts hydraulic gage is communicated with the gum elastic capsule by connection tube.
The sliding axle upper end can be made into the difformity structure with the set axle head in cylinder barrel lower cover lower end, and corresponding coupling with various external fixers connects.
Utilize the fixing fracture of external fixer and elastic device, when sliding axle fine motion stop screw screws out, fractured bones is under axial compressive force, by hold-down screw on the skeleton and external fixer upper and lower side, impel sliding axle to move down pressurization, compression spring or gum elastic capsule, because but the sliding axle fine motion moves down 2 millimeters, drive thereupon and control fractured bones also fine motion move down 2 millimeters, be subjected to the pressure effect of fracture end, can stimulate the fracture end callus to generate, avoid fracture end to produce stress shielding, the axial compressive force size is clearly shown by pressure display unit or hydraulic gage by pressure transducer or connection tube.For comminuted fracture, axial compressive force easily makes sclerite distortion and displacement, needs to screw in stop screw, and the limit slippage axle moves down, and fracture end can not produce fine motion and pressure, treats the healing of fracture end soft tissue firmly, when sclerite is difficult for displacement, screws out stop screw and gets final product.When fracture end needs a less Pressure stimulation, can screw the lower cover pressure regulating screw, make spring or gum elastic capsule pressurized by pressure transducer or capsule base, axial downforce of sliding axle and fine motion amount are reduced, and then control fracture end pressure stimulate.The visual fracture concrete condition of fracture end pressure is regulated as required at any time, to help the fracture end healing.
This elastic device can mate the external fixer of any difformity structure, constitutes the elasticity external fixer.When the limbs of fracture are subjected to axial compressive force, the elasticity external fixer axially has 2 millimeters fine motion scope, thereby make the fracture end fine motion and produce an interaction force, stimulate the fracture end callus to generate, avoided the external fixer stress shielding to form osteoporosis, but accelerating bone healing speed strengthens the intensity of healing sclerotin, effectively prevents the generation of fracture delayed healing or disunion.
