Abstract
An outer fixing skeleton elastic device for orthopedics clinical application consists of a cylinder barrel, a sliding axle inside the cylinder barrel, an elastic device, a sliding nail body and a pressurizing hole. The cylinder barrel wall is provided with a sliding axle micromotion limit screw, a fastening screw, an anti-spin rivet and a pressurizing hole along the radial direction. The cylinder barrel wall can be manufactured as that the inner diameter of the upper part matched with the sliding axle is larger than the inner diameter of the lower part and can also be manufactured as that the inner diameters of the upper and the lower parts are same. The elastic device can be made into spring type or elastic capsule type. The sliding nail body is connected with the cylinder barrel in a sliding way. The elastic device can be matched with the outer fixing skeleton of any different shapes and structures to form an outer elastic fixing skeleton. When a catagmatic limb bears the axial pressure, the outer elastic fixing frame has micromotion at the axial direction, so as to ensure that a fracture end is jiggled and produces an interaction force to stimulate the porosis at the fracture end. The elastic device of the present invention avoids that the outer fixing skeleton shields stress to cause the osteoporosis, can quicken the fracture cicatrization and improve the bony intensity and effectively prevents delayed fracture cicatrization or nonunion.
Description
Affiliated technical field
The present invention 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.The rotation in the horizontal direction of the uncontrollable sliding axle of existing externally fixing support elastic device is so fracture end can rotate the healing that is not easy to fracture in the horizontal direction.
Summary of the invention
The objective of the invention 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 prevent sliding axle rotation in the horizontal direction, 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 sliding axle, elastic device, the sliding moving nail body of cylinder barrel, cylinder barrel inside, the cylinder barrel wall radially is provided with sliding axle fine motion stop screw, trip bolt, anti-rivet, the pressurization hole of revolving, the stop screw head end is cylindric, 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 moves down.Can depending on the circumstances or the needs of the situation make the different stop screw of head end diameter dimension.Prevent that revolving rivet radially runs through sliding axle, prevents to rotate on the sliding axle horizontal direction.The trip bolt head end is cylindric, and corresponding with sliding moving nail body top, trip bolt is fashionable from outer buttons, can prevent rotating on the sliding stop nail body horizontal direction and moving up and down.
Sliding moving nail body and cylinder barrel are slidingly connected, and lower sides is established the pressurization hole, when moving up, can pass through pressure conduction device, spring or gum elastic capsule and produce active force upwards.
Cylinder barrel 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.Establish the fine motion gap between step and the bottom surface, sliding axle cooperation place.
It is identical that the cylinder barrel barrel can be made the upper and lower part internal diameter, barrel radially is not provided with sliding axle fine motion stop screw, stop nut or limiting gasket are set on sliding axle, stop nut is threaded with sliding axle, and turn up and down is positioned at the cylinder barrel top, and cylinder barrel is established the fine motion gap between the upper end, stop nut is during from the top backspin, and its lower end can connect with the cylinder barrel upper end, and the limit slippage axle moves down; Scale is set on the sliding axle, can determines stop nut and cylinder barrel upper end fine motion gap length according to circumstances.Limiting gasket is positioned at cylinder barrel top, but the limit slippage axle moves down when inserting.Sliding axle and cylinder barrel are slidingly connected, but fine motion moves down under responsive to axial force.
The elastic device of cylinder barrel inside can be made multi-form.
Elastic device is generally made spring or elastic capsule formula, and elastic capsule is the gum elastic capsule that internal-filling liquid is pressed oil, and spring places between sliding axle and the pressure conduction device; The gum elastic capsule places between sliding axle and the sliding moving nail body, and the gum elastic capsule also can be made as and place between sliding axle and the pressure conduction device.
Pressure conduction device connection tube is connected with Pressure gauge by casing joint.
The radially set rivet hole of sliding axle revolves rivet and adapts with anti-, and its axial aperture makes sliding axle revolve rivet shaft to moving down along anti-greater than horizontal aperture.Axial aperture length is more than or equal to anti-fine motion gap sum of revolving on rivet diameter and the sliding axle axial direction.
The sliding axle upper end can be made into the difformity structure with sliding moving nail body lower end, and corresponding coupling with various external fixers connects.
Utilize the fixing fracture of external fixer and this elastic device, when revolving on back-out of sliding axle fine motion stop screw or the stop nut, 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 or backspin stop nut, 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, screw out stop screw or on revolve stop nut and get final product, can select the different stop screw of diameter or definite different stop nut turn scope 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 increases the intensity of healing sclerotin, effectively prevents the generation of fracture delayed healing or disunion.
