Abstract
The utility model relates to a half-ring plane adjustable external fixing rack, belonging to a clinical therapeutic instrument. The fixing rack is a half-ring biplanar metal framework, which is mainly composed of a needle holding screw bolt, an upper and a lower half-ring steel plates, and an upper and a lower sleeves, wherein, a bidirectional connecting rod is screwed and sheathed on the screw rod to form one sleeve. The upper end of the bidirectional connecting rod is hinged with the half-ring steel plate on the upper part, and the sleeve at the lower end is connected with the half-ring steel plate on the lower part through the screw. The upper part and the lower part of the screw rod of the bidirectional connecting rod respectively form a positive and a reverse thread structure. The needle holding screw is arranged in an arc-shaped groove on each half-ring steel plate. The utility model not only has the functions of compression, fixation, drag and extension, but also has the function of reshaping curved skeletons.
Description
This utility model belongs to the clinical treatment apparatus, mainly proposes the adjustable external fixer in a kind of semi-ring plane.
The external fixer kind of orthopaedics clinical practice at present is more, and its structural design preferably resolves axial compression and tractive function, thereby has fracture of fixing and the effect that prolongs limbs, but aspect deformity backbone's treatment, still lacks certain orthopaedic function.
The purpose of this utility model is to propose the adjustable external fixer in a kind of semi-ring plane, makes its fracture that is used for the lower limb long bone and orthopaedic treatment and makes it have better therapeutic effect.
This utility model is finished the technical scheme that its invention task taked: this fixed mount is a semi-ring biplane metal framework structure, mainly by hold the pin bolt, up and down the semi-ring steel plate and by reverse-flighted screw and rotation set the two-way mobile link that sleeve constituted up and down on screw rod form; Two-way mobile link upper end is hinged with top semi-ring steel plate, lower sleeve is connected by screw with bottom semi-ring steel plate, the screw rod top and the bottom of two-way mobile link are forward and reverse helicitic texture, be provided with in the arcuate groove on the semi-ring steel plate and hold the pin bolt, fixing fracture is connected with its two ends of draw point holds on the pin bolt.
When rotation during reverse-flighted screw, the upper and lower side sleeve that is screwed with it just can along its axis respectively up and down direction move, make length of connecting rod obtain changing.Because upper end sleeve and the hinged formation Movable joint of semi-ring steel plate, so when adjusting the direction unanimity that is equipped with Movable joint face (even top semi-ring steel plate pendulum angle unanimity), by regulating the length of each two-way connecting rod, the spacing of the semi-ring steel plate that two ends with it link to each other is changed relatively, can also make top semi-ring steel plate be inclined to the angle along its joint motion direction, be installed in the draw point held on the pin bolt to the pressurization of backbone's row thereby drive, effect such as strut and prize.
Compare with other kind external fixator, this utility model fixed mount not only possesses the fixing function of extending with tractive of compression, and has the orthopaedic function key to crooked (one-tenth angle).
Embodiment:
Accompanying drawing 1 is this utility model structural representation.
In conjunction with the accompanying drawings this utility model structure is further specified:
As shown in Figure 1, it is a semi-ring biplane metal framework structure, mainly by holding pin bolt 1, upper and lower semi-ring steel plate 2 and form by the two-way mobile link that reverse-flighted screw 5, the rotation set upper and lower sleeve 4,6 on screw rod is constituted, the upper end of two-way mobile link and top semi-ring steel plate are hinged, and promptly top semi-ring steel plate and upper end sleeve 4 are hinged.Concrete structure is that top semi-ring steel plate is by connecting pin and upper end sleeve 4 formation articulated structures; Connect the U-lag that pin has pin-and-hole by the top nut compressing in semi-ring steel plate upper and lower part and is positioned at the sleeve upper end, the semi-ring steel plate can be swung, form " Movable joint " of articulated structure around bearing pin thereby pass a bearing pin.Lower sleeve portion 6 same thread bush are on screw rod 5, and its lower end is that female thread is connected with bottom semi-ring steel plate by screw.The thread rotary orientation of screw rod 5 upper and lower parts of two-way mobile link is opposite, turn reverse-flighted screw 5 (screw rod 5 is rotated), the upper and lower side sleeve that is screwed with it just can along its axis up and down direction move, make length of connecting rod obtain changing.Hold pin bolt 1 and the two-way mobile link that are installed in the semi-ring steel plate arcuate groove can be according to every draw point position and the angles through the backbone, along in the groove and axis direction adjust accordingly.
Among the embodiment, in the arcuate groove of its collar extension both sides of semi-ring steel plate, be separately installed with two and hold pin bolt 1 and 1 two-way mobile link.
Claims (1)
1, the adjustable external fixer in a kind of semi-ring plane, it is characterized in that this fixed mount is a semi-ring biplane metal framework structure, mainly by holding pin bolt (1), semi-ring steel plate (2) and form up and down by the two-way mobile link that reverse-flighted screw (5), the rotation set sleeve up and down (4) (6) on screw rod is constituted; Two-way mobile link upper end is hinged with top semi-ring steel plate, lower sleeve (6) is connected by screw with bottom semi-ring steel plate, the screw rod of two-way mobile link (5) top and the bottom are forward and reverse helicitic texture, are provided with in the arcuate groove on the semi-ring steel plate and hold pin bolt (1).
