The utility model comprises six adjustable L-shaped external fixation arms, six upper and lower sliding grooves, three load bearing screw rods and four bone penetrating needles which are respectively provided with an internal screw thread and an external screw thread. The utility model leads one end of bone fracture to rotate from top to bottom, backwards and forwards and from left to right in three-dimensional space, and leads angulation deformity to be corrected. The utility model does not require to pressurize a soft tissue. The utility model leads apposition to be good, leads blood movement to be fluent, leads union of fracture to be quick, and leads functional recovery to be early. The utility model has the advantages of simple methods, complete restoring position, little pain, good curative effect, and low cost for treating bone fracture and bone diseases without using a knife.

Description

The three-dimensional reduction fixture device of interior pressurization

This utility model relates to the three-dimensional reduction fixture device of pressurization in a kind of orthopedic medical device.

The existing at home and abroad at present reduction of the fracture fixedly mostly adopts the way of the outer pressurization of single-arm shift bracket to come correction deformity in the external support.And there is not a kind of holder that can reset to fracture of shaft of femur or other irreducible extremity fracturies, sometimes the fracture patient soft tissue damage is serious, blood circulation is affected, if adopting existing outer adding pressure type method corrects, then the more influenced and stiff end of local blood circulation is easy to slippage influence healing, and the compression strength deficiency is difficult for correcting rotation deformity, and reset effect is not ideal enough.

The purpose of this utility model is to provide a kind of new interior pressurization exterior fixation bracket, by adjusting screw rod on the reset cradle and wearing screw on the spicule, reaches the purpose that some irreducibles of treatment are fractured according to correcting to require to prolong or pressurize.

This utility model is finished in the following way.Should 6 adjustable L type external fixation arm of forces be set the three-dimensional reduction fixture device of interior pressurization, two are fixedly connected by the collar and scalable chute between the arm of force, constitute 3 semi-rings.Connect by screw rod between the semi-ring L type arm of force.The screw rod two ends are provided with screw thread, and the L type arm of force and screw rod junction are provided with nut.Nut on the L type arm of force is connected with screw rod end screw thread formation.Between the L type arm of force screw thread asseous pin is set.The screw thread asseous pin is connected by fixed arm with the L type arm of force.Screw thread asseous pin stage casing is provided with rough grain.One end is provided with fine thread.L type arm of force end is provided with chute, and nut is set on the chute, is connected and fixed with fixing hole on the fixed arm of screw thread asseous pin setting.The screw thread asseous pin does not have the end of thread to be fixed with jackscrew.

After using this device, can correct deformities such as overlapping, separation, front and back, side, one-tenth angle and rotation, and there are semi-ring and three screw rods to connect, epimere weight is directly passed in far-end by wearing spicule and screw rod, fracture end need not bear a heavy burden, do not have the compressing of external fixation and soft tissue: blood fortune is good, can early ambulant in addition.So, can promote union of fracture and make the function early recovery, avoid muscle adhesion, machineization and joint stiffness, thereby greatly recovered the function of limbs.

Drawings and Examples:

Fig. 1 is the three-dimensional reduction fixture device structural representation of interior pressurization

Fig. 2 is the three-dimensional reduction fixture device major part of an interior pressurization exploded view

1 is the fixing arm of force among Fig. 1, the 2nd, and the collar, 3 is chutes between two arm of forces, the 4th, screw rod, the 5th, screw rod end screw thread, the 6th, arm of force end nut, the 7th, arm of force end chute, the 8th, fixed arm nut, the 9th, asseous pin fixed arm, the 10th, the hole on the fixed arm, the 11st, the screw thread asseous pin, the 12nd, asseous pin end fine thread, the 13rd, asseous pin stage casing wood snail stricture of vagina, the 14th, jackscrew.

During use, earlier with the fracture end manual reduction, the sending down the fishbone bar is respectively squeezed into two pieces of screw thread asseous pins to wood snail stricture of vagina place, stage casing (13) by distance on fracture end, make wood grain (13) cross key with fixed backbone on asseous pin (11), screw thread asseous pin end fine thread (12) is positioned at outside the skin of limbs both sides.6 L type arm of forces (1) end sideslip grooves (3) are connected with bottom bar and the collar (2) Song Song, and at two tops connection, two connecting rods (4), regulate and fix the width of three semi-rings according to suffering from the limb thickness, screw thread asseous pin 13 is penetrated fixed arm (9), and fixed arm pine pine is fixed in the vertical runner (7) of semi-ring, under the X line, turn the nut (6) at three connecting rods (4) two ends then, make key broken ends of fractured bone prolongation or pressurization correct overlapping or the separation deformity, tighten fixed bar two ends attaching nut (6) after the satisfaction, then fixed arm (9) top nut (8) and the jackscrew (14) of near-end being worn the spicule two ends tightened, adjust two of far-ends then and wear the fixed arm (9) of spicule (11) on semi-ring vertical runner (7), a side slides up and down or slides, to correct front and back and rotation displacement and front and back angulation deformity, correct the back fastening nut, last situation according to lateral displacement and side angulation deformity, adjust the nut of wearing spicule one end (8) on the fixed arm (9), all deformities are obtained fully and satisfied rectification, all hold-down nuts are tightened, tear sheet open and can send into the ward, the early loading activity after normal.
