Description
Technical field
The utility model belongs to the field of medical instrument technology, is related to a kind of split type bone tractor.
Background technique
Bone traction is mainly used for the treatment of the certain diseases of four limbs, or is benefit as Preoperative Method, the means of postoperative braking
Sclerotin is passed through with thick steel needle or traction tongs, tractive force is made directly to arrive at damage location by bone, play reset, fixation and is stopped
The effect of breath；Its advantage is that biggish trailing weight can be born, resistance is smaller, can correct bone efficiently against muscular tone
Deformity caused by folding overlapping or abarticulation；Convenient for inspection suffering limb after traction.
The traction bow clinically used at present is integral type, needs manual bending traction bow in installation course, is easy to aggravate
Displacement fracture, making patients' pain, traction bow are unfavorable for line of force adjusting after placing.
Utility model content
The purpose of this utility model is in view of the problems of the existing technology to provide a kind of split type bone tractor.
The specific technical solution of the utility model is as follows:
A kind of split type bone tractor, including traction bow, the thick steel needle being set on traction bow, the draft arm is by being in L
First draft arm of shape and the second L-shaped draft arm dock, and are provided with inserting groove on the cross bar of first draft arm
Road, the cross bar of the second draft arm are inserted into the grafting conduit, the vertical bar end difference of first draft arm and the second draft arm
It is provided with through-hole, thick steel needle passes through the through-hole；
It is set with lantern ring on the cross bar of first draft arm, which can move linearly along the cross bar of the first draft arm,
Collar footprint is provided with draught line drag hook；
Locking device is provided between the lantern ring and the cross bar of the first draft arm；
Locking device is provided between the cross bar of first draft arm and the cross bar of the second draft arm；
Locking device is provided on the through-hole；
The cross section of the cross bar of the grafting conduit and the second draft arm is semicircle, guarantees the first draft arm and second
Draft arm docking is stablized.
The utility model has the following beneficial effects:
The utility model is using two L-shaped draft arm composition traction bows being oppositely arranged, installing and dismounting polyvinyl chloride side
Just, while the distance between adjustable draft arm, realization traction bow open distance adjusting, so that it is suitable for different parts traction,
It is not limited by patient size.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
A kind of split type bone tractor as shown in Figure 1, it is described to lead including traction bow, the thick steel needle being set on traction bow 1
It draws a bow and is docked by the first L-shaped draft arm 2 and the second L-shaped draft arm 3, on the cross bar of first draft arm 2
It is provided with grafting conduit 4, the cross bar of the second draft arm 3 is inserted into the grafting conduit 4, first draft arm 2 and the second traction
The vertical bar end of arm 3 is respectively arranged with through-hole 5, and thick steel needle 1 passes through the through-hole 5；It is set on the cross bar of first draft arm 2
Lantern ring 6, the lantern ring 6 can move linearly along the cross bar of the first draft arm 2, and 6 bottom of lantern ring is provided with draught line drag hook 7；The set
Locking device is provided between ring 6 and the cross bar of the first draft arm 2；The cross bar of first draft arm 2 and the second draft arm 3
Locking device is provided between cross bar；Locking device is provided on the through-hole 5；The grafting conduit 4 and the second draft arm 3
Cross bar cross section be semicircle.
When carrying out skeletal traction to patient using the utility model, thick steel needle 1 is passed through to the position of threading a needle of patient, then by bone
1 both ends of round needle are set with the first draft arm 2 and the second draft arm 3, and the cross bar of the second draft arm 3 is inserted into the first draft arm
In 2 grafting conduit 4, the docking of the first draft arm 2 and the second draft arm 3 is completed, the cross bar by adjusting the second draft arm 3 exists
The adjusting of traction bow opening width is realized in the position of grafting conduit 4, is drawn by locking device to traction bow and thick steel needle 1, first
Arm 2 is locked with the second draft arm 3, adjustment collar 6 the cross bar of the first draft arm 2 position and pass through locking device lock
Tightly, load is hung up on draught line drag hook 7, and skeletal traction is carried out to patient.
