Abstract
An external fixer elastic device for orthopaedics clinical use, comprises a cylinder barrel, and a sliding shaft and an elastic device in the cylinder. The cylinder wall is radially provided with a sliding shaft fretting stop screw, and the elastic device is made into spring type or elastic capsule type. The elastic device can match any external fixer of different shapes and structures to form an elastic external fixer. When the fractured limb is under the axial pressure, the elastic external fixer axially move slightly to promote the fractured end to move slightly and produce an interaction force, so as to promote the formation of the callus on the fractured end. Therefore, the osteoporosis caused by the stress shielding of external fixer is avoided, and the fracture healing speed is quickened, and the strength of the healed bone is increased, thus to effectively prevent the cases of fracture delayed healing or nonunion.
Description
Affiliated technical field
This utility model relates to 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 is to remedy the defective that current use external fixer treatment fracture exists, employing has a kind of externally fixing support elastic device of elasticity fine motion adjusting device, can effectively prevent to produce stress shielding, avoid forming osteoporosis, and can stimulate the fracture end callus to generate accelerating bone healing.
The technical scheme of this externally fixing support elastic device is: its composition has the sliding axle and the elastic device of cylinder barrel and cylinder barrel inside.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, and during back-out, but sliding axle fine motion under responsive to axial force moves down.Can depending on the circumstances or the needs of the situation make the different stop screw of head end diameter dimension.
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 barrel internal diameter step.
The elastic device of cylinder barrel inside can be made multi-form.
Elastic device is generally made spring or elastic capsule formula.Spring comprises spring and lower bottom base, and spring places between sliding axle and the lower bottom base; 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.
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 this elastic device, when sliding axle fine motion stop screw screws out, fractured bones by hold-down screw on the skeleton and external fixer upper and lower side, impels sliding axle to move down pressurization under axial compressive force, compression spring or gum elastic capsule, because but the sliding axle fine motion moves down, drive thereupon and control fractured bones also fine motion move down, be subjected to the pressure effect of fracture end, can stimulate the fracture end callus to generate, avoid fracture end to produce stress shielding.For comminuted fracture, axial compressive force easily makes sclerite distortion and displacement, need to screw in stop screw, the limit slippage axle moves down, fracture end can not produce fine motion and pressure, treats the healing of fracture end soft tissue firmly, when sclerite is difficult for displacement, the back-out stop screw gets final product, and can select the different stop screw of diameter for use for the difference of different comminuted fracture and healing time length thereof.
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 fine motion, 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.
