Description
Technical field
The invention belongs to field of medical products, are related to fracture fixation device, and in particular to a kind of fracture of lower limb fixed traction
Device.
Background technique
When fracture of lower limb or abarticulation, by the effect of lower limb muscles natural shrinking power, fracture usually occur is in angle, cripetura
Phenomena such as unstable after displacement and reduction of joint dislocation, in order to fight contraction of muscle, clinically frequently with traction therapeutic, traction is at present
Limb needs to remain certain position.Original Thomas's frame and Blang's Brown's frame, is that bandage is wrapped in metal frame,
Suffering limb shank is placed on bandage, and the design of metal frame tail end has hauling block, and traction weight is remote by traction rope, hauling block and fracture
End is connected, and the therapeutic purposes completed confrontation muscular strength, reach fracture or embolia obtain good therapeutic effect, in clinic
It is widely used so far.With the continuous development of medical technology, since original Thomas's frame and Brown's frame are ferrous material weldering
It is connected into type, rotproofness is poor, easily gets rusty, and inconvenience storage and keeping have been used stainless steel material instead and have been process, well solved
It gets rusty and Anticorrosion, and hitch frame is improved, many novel lower limb hitch frames occur, compensate for many deficiencies, but pass through
There is also following defects for long-time clinical observation: the height of (A) hitch frame is fixed, and is suitable for patient of medium height, and stature is excessively high
Or child patient influences traction and therapeutic effect in use, position is obviously uncomfortable.(B) hauling block position is fixed, and restriction is led
Draw that angle is also invariable, is not able to satisfy the needs of different type fracture patient traction therapeutic.(C) suffering limb is placed on is twined with bandage
Around cloth support on, thigh resists tractive resistance by circular bandage, and prolonged traction will appear circular bandage displacement and become
Shape makes local soft tissue be pressurized, and hitch frame is made directly to block Ya popliteal nest and perineum, causes local discomfort, and patient is often voluntarily
Position is adjusted, traction and therapeutic effect are influenced.
A kind of leg traction frame is also disclosed in the prior art, it is made of body frame, crane and folding stand three parts.Its
Be characterized in that the socket of body frame and crane is connected, can up-down stretch, fixed, can be suffered from according to each age group difference height by elevator lock
The needs of person adjust crane height；Lateral arc concave shape is designed on body frame, indulges inflexed supporting plate, is suitable for drawing limbs
Comfortable placement and disinfection convenient for cleaning；Folding stand is connected by steering column shaft thereon with body frame, when with body frame upright position
It can move up and down, changeable traction angle and lower the center of gravity in the sliding groove of body frame, it is vertical with body frame and at extreme higher position,
It can be turned back 90 ° by diverter to body frame direction, and body frame parallel stacking, it is small to occupy space, convenient nursing and storage；Multiple bands
The design of bearing hauling block and support frame is, it can be achieved that multi-angle and compound traction, reduce tractive force and lose, keep tractive force
It is balanced.Although having done Optimizing Reconstruction to tractor in the prior art, tractor in the prior art is still inadequate just
It takes, uses nor easily, being not suitable for and first aid scene.
As the development and aging of population of the industries such as China's traffic, building aggravate, lead to traffic accident injury, building tumble injury and old
Year, the patient of osteoporotic fracture increased year by year.Meanwhile modern war causes to fight with the development and use of high yield weapon
Often there is also fracture under a variety of Risk Factors by the wounded.In emergency care of trauma, the carrying of fracture being fixed temporarily with the wounded
It is mostly important and crucial one of technology, and the TCCC committee of the U.S. also has been recognized that Boards wall and the relevant technologies are one
It is suitble to wartime war to rescue the important technical of personnel and non-wartime first-aid personnel.How effectively fracture to be consolidated rapidly
Calmly, can the wounded be transferred rapidly and is given treatment to and play very important effect.Currently used first aid of fracture fixes device
Boards wall, have many advantages, such as it is easy to operate, it is applied widely, especially for being fixed temporarily for limbs fracture, Neng Gouqi
To preferable fixed effect, mitigate pain on the way in casualty evacuation, stops blooding, reduce the incidence of fat embolism syndrome, thus
Avoid secondary damage.
However, the fracture fixation device that the current first aid in China uses is worldwide still in relatively backward state.With
Toward the most or wooden splint for being used for first aid fracture fixation, not readily portable, fixed effect is poor, at the same need to cooperate bandage and
Triangle bandage uses, and whole process is time-consuming and laborious, and good fixed effect is not achieved, and crushes for merging the opening of soft tissue injury
Type fracture, can not be fixed using it；Though and rolled type plywood have plasticity, this greatly reduces its fixing intensity, one
The triangle bandage and bandage that denier uses are not fixed firmly, and easily cause secondary damage in the handling process, aggravate the condition of the injury；Most attach most importance to
It wants, does not have the effect drawn along fracture site, wounded's local pain can not be mitigated, such as displacement or comminuted fracture wound
Member's transhipment time is long, and malunion or secondary displacement can then lose operative treatment chance, leave all the life to patient and the wounded
Deformity and it is sorry.
