Description
Technical field
The present invention relates to medical instruments fields, more particularly to a kind of board-like outer fixed branch for trauma fracture treatment
Frame.
Background technique
During treating trauma fracture, the operative treatment mode of interior fixed reset and outer fixed reset is mostly used, it is interior
Fixed reset is suitble to closed trauma to merge the treatment fractured；Outer fixed reset is often suitble to open wound to merge controlling for fracture
It treats.Outer fixed reset operation is needed using exterior fixing rack.
The structure type of exterior fixing rack mainly has monoblock type exterior fixing rack, integral type exterior fixing rack, ring frame at present
Formula exterior fixing rack and Combined type external fixed support.
Monoblock type exterior fixing rack as the term suggests this exterior fixing rack is overall structure, its advantage is that integral strength compared with
It is high.The disadvantage is that this kind of exterior fixing rack overall structure lack flexibility ratio, have a single function, overall structure it is very heavy.It is controlled in operation
It during treatment, is difficult to avoid important blood vessel and nerve sometimes, often results in the difficulty of operative treatment or the secondary wound of patient
Evil, and be difficult to accurately in more complicated trauma fracture resets.The current this less use of exterior fixing rack.
Integral type exterior fixing rack is improved and optimizated on the basis of monoblock type exterior fixing rack, its advantage is that whole
Intensity is higher, and structure has certain flexibility ratio；The disadvantage is that the overall structure of this kind of exterior fixing rack is still very heavy, outer fixed branch
The adjustable extent of frame is smaller, and function is seldom；In surgical procedure, although the certain flexibility ratio having, because can
Adjustable range is smaller, still can not effectively avoid important blood vessel and nerve, will cause the difficulty of operative treatment, cannot effectively keep away
Exempt from the secondary injury of patient, can not accomplish to accomplish in more complicated trauma fracture resets accurate.
Ring frame exterior fixing rack is to use circular semi-ring frame, loopful frame or shape of a hoof ring frame for primary structure, auxiliary
The exterior fixing rack constituted with connecting rod of keeping straight on.The advantages of this exterior fixing rack, is flexibility ratio with higher, whole strong
It spends higher.The disadvantage is that the structure of this exterior fixing rack is very complicated, overall dimensions are very big, very heavy.In surgical procedure,
It is required that very stringent, very high to mounting technique and installation accuracy requirement, reduction of the fracture process complexity is cumbersome in operation, and function is seldom.
Current this exterior fixing rack has been combined formula exterior fixing rack substitution, seldom uses in clinical practice.
Combined type external fixed support is largely used under the background that modern industry and modern material science and technology develop rapidly
Novel exterior fixing rack, the application of high-performance, high-strength light metal material, composite material, high molecular material make outer fixed branch
Frame mitigation weight, reduction size, raising performance have possible.It the advantage is that operation uses simple installation, flexible adjustment, weight
Gently, adaptability is good, function is more, reduction of the fracture process is simple in operation, and can avoid important blood vessel and nerve well.It lacks
Although the overall dimensions that point is Combined type external fixed support are reduced, but still bigger；Fixed branch followed by outside combined type
Frame is using single component as assembled unit, and required number of components is big, needs to realize using different functional components different
Function causes the composition of Combined type external fixed support and using very complicated；And patient face convalescence after surgery it is daily
Movable difficult, winter is difficult to wear the clothes warming, perplexs with many lives are added.
Due to fixed outside monoblock type exterior fixing rack, integral type exterior fixing rack, ring frame exterior fixing rack and combined type
The various disadvantages of bracket cause some obstacles to the popularity of its clinical application.Urgently exterior fixing rack be directed to
Property improvement, on the basis of Combined type external fixed support is flexible, light, easy-to-use, adaptability is good, fixed branch outside the formula that integrally combines
The advantage that the intensity of frame is high, structure is simple, designs and develops the better exterior fixing rack of service performance.
