Description
Technical field
The utility model is related to a kind of orthopedics tractor, belongs to technical field of medical instruments.
Background technology
The method of present four limb traction has skin traction and Bone traction：Skin traction was primarily directed to elderly patient and less than 8 years old
Children use, and its effective traction amount is small, and skin bubble easily occurs because pulling tension force, and Bone traction is normal on Orthopedic Clinical
Traction method, but the method that clinically uses is now：With hammer by one piece of Kirschner wire or steinman pin from the side of bone
Squeeze into, offside skeletal muscle and skin are passed by ossis, this method can make patient produce the frightened heart before traction is implemented
Reason, and pull needle will run through offside through ossis in this approach, and when releasing traction from now on, pull needle equally will be through
Ossis is crossed, and Iodophor and alcohol are extremely difficult to the requirement of orthopaedics sterilization, add the chance of deep infection, cause institute
Interior infection is possible, while increasing during pull needle is squeezed into because impact external force vibrations can cause suffering limb fracture pain to aggravate
Plus patient suffering, or even induce Other diseases, such as hypertension, asthma.
Utility model content
Originally practical purpose is to provide a kind of arm of force adjustable orthopedics tractor, and its arm of force is adjustable, is adapted to difference
The patient of physique, and the method for not only improving Orthopedic Clinical Bone traction, reduce artificial wound, make skeletal traction simpler
Folk prescription just, while decreasing patient suffering, reduces the chance of nosocomial infection, reduces complication.
To achieve these goals, the utility model employs following technical proposals.A kind of adjustable orthopaedics traction of the arm of force
Device, including traction bow, traction bow, which is provided with left draft arm and right draft arm, left draft arm, is set with left slider, and left slider is provided with spiral shell
Hole, one end of left arm bar is fixed on left slider by screw I, and left slider is fixed on left draft arm by screw I simultaneously, left
The other end of arm bar installs left by the left tapping screw fixing nut of screw II connections, in the left tapping screw fixing nut
Tapping screw；Right sliding block is set with right draft arm, right sliding block is provided with screw, and one end of right arm bar is fixed on the right side by screw IV
On sliding block, right sliding block is fixed on right draft arm by screw IV simultaneously, and the other end of right arm bar is right certainly by screw III connections
Attack in screw fixing nut, the right tapping screw fixing nut and right tapping screw is installed.
Further, the traction bow is U-shaped, and left draft arm and right draft arm are square column type or rectangle.
The beneficial effect of this practical bone tractor：Simple in construction, the arm of force is adjustable, moves back nail convenient.It can play Bone traction
Effect, and the acceptant this treatment method of patient, will not making patients pain and cause fear, only needed when releasing traction
Bilateral moves back nail, reduces complication.

Embodiment
In order to make it easy to understand, making specifically to illustrate below in conjunction with the accompanying drawings to the utility model.
Reference picture 1, a kind of adjustable orthopedics tractor of the arm of force, including U-shaped traction bow 1, traction bow 1 are provided with left draft arm
With right draft arm, left slider 21 is set with left draft arm, left slider 21 is provided with screw, and one end of left arm bar 31 passes through screw I
61 are fixed on left slider 21, and left slider 21 is fixed on left draft arm by screw I 61 simultaneously, the other end of left arm bar 31
Connected by screw II 62 and left self tapping spiral shell is installed in left tapping screw fixing nut 41, the left tapping screw fixing nut 41
Nail 51；Right sliding block 22 is set with right draft arm, right sliding block 22 is provided with screw, and one end of right arm bar 32 is fixed by screw IV64
On right sliding block 22, right sliding block 22 is fixed on right draft arm by screw IV64 simultaneously, and the other end of right arm bar 32 passes through spiral shell
Follow closely and right tapping screw 52 is installed in the right tapping screw fixing nut 42 of III63 connections, the right tapping screw fixing nut 42.
In the present embodiment, left draft arm and right draft arm are square column types, naturally it is also possible to using shapes such as rectangles.Correspondence
Left slider 21 and right sliding block 22, square hole or rectangular opening can be used.
To be designed beautifully, the two ends of left arm bar 31 and right arm bar 32 use arc transition, and left tapping screw fixes spiral shell
The upper and lower ends of mother 41 and right tapping screw fixing nut 42 also use arc transition.Square shown in certain accompanying drawing is also can
With.
In the utility model, traction bow 1 is used to conduct external force, determines that suffering limb traction plane and direction etc. are acted on；Left slider
21 and right sliding block 22 play connection traction bow, the conduction effect such as external force；Left tapping screw 51 and right tapping screw 52 play fixation
Bone, determination lead and conduction external force effect together with traction bow 1；Left arm bar 31 and right arm bar 32 are together with screw
Play a part of regulation tapping screw torque arm length and conduct external force；Spanner is also equipped with, reinforcing screw-nut effect is played.
Application principle of the present utility model：Twisted by the tapping screw for being fixed on both sides on traction bow 1 through integumentary musculature
Enter bone (screw is without through ossis) and suffering limb distal end bone is vised into fixation, then introduced external force by traction bow 1, reach
The purpose of Bone traction.
The patient of such as one fracture of femoral shaft, need to do tibial tubercle Bone traction：The thick of position is drawn according to needed for suffering limb
Carefully, the left slider 21 and right sliding block 22 for fixing and mutually being fixed with traction bow 1, and left arm bar 31 and right arm bar are adjusted with spanner
32, then left tapping screw fixing nut 41 and right tapping screw fixing nut 42 are fixed, the arm of force of tapping screw can not be long,
Tapping screw can be caused to deform in distraction procedure if long, produce shearing, reduce effective traction, draw-gear
After installing, sterilization paving in traction position is single, and 2cm makees local anaesthesia at 2cm backward again below the tibial tubercle, by both sides self tapping spiral shell
Nail is alternately screwed into, and Traction bends after both sides tapping screw enters shin bone certain depth, feels that tapping screw fixation can
Bear necessarily to draw strength, even if then connected on traction bow appropriate weight title stone roller complete, when releasing traction from now on
As long as nail is moved back in sterilization again at the tapping screw of both sides.
