Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of exterior fixation bracket for bone lengthening.
Background technology
Exterior fixation bracket is to be connected and fixing with device outside by the draw point being interspersed in bone, imposes bone and axially adds
Pressure, traction (limbs or bone transport).It is that current clinical orthopaedics is in treatment long bone fracture and the most frequently used operation of malformation correction
Method.In prior art, exterior fixation bracket has monolateral exterior fixation bracket, hook and slot exterior fixation bracket, ring external fixation support.It is main
Act on and be used to amputation is fixed and pressurizes, prevent knochenbruch from reversing and deformation, to promote the healing of fracture, but can not
Realize the malformation correction to bone or the therapeutical effect of prolongation.
Summary of the invention
It is an object of the invention to overcome the deficiency in existing exterior fixation bracket technology, it is provided that " a kind of for bone lengthening
Exterior fixation bracket ".The present invention has simple in construction, cost is low, volume is little, fixation is reliable, operation sequence is convenient and simple
Advantage, be that one can complete to fix, pressurize, the multi-functional extenal fixation that can realize again the malformation correction to bone or prolongation props up
Frame.
For achieving the above object, the technical solution used in the present invention is: a kind of exterior fixation bracket for bone lengthening,
Mainly it is made up of semi-ring connecting rod, spicule, extender parts and support bar.Described semi-ring connecting rod is open pentagon shape
Shape, be arranged two in parallel at upper-lower position.Support bar is the most equidistant at the two ends of semi-ring connecting rod center edge be arranged two in parallel
Root, its two ends are fastenedly connected with semi-ring connecting rod by the fastening of bar bar respectively.Two ends and centre bit in semi-ring connecting rod
Put and be provided with spicule the most simultaneously, be fastenedly connected with semi-ring connecting rod by shank fastening respectively.
The main technical schemes that the present invention is taked is, described extender parts, by support bar, locking nut, regulate core bar
And regulation handle composition.Described regulation taper knob is contained on support bar, sets at the cavity position near first locking nut one end
There is female thread.It is respectively arranged with first external thread section and second suitable with regulating handle female thread at the two ends of regulation core bar
External thread section, described regulation core bar wear the first locking nut and its two ends of the second locking nut respectively with regulation handle and support
Bar is threaded.
Further technical scheme is that described support bar is cavity two sections combinative structure, by with regulation core bar two
Hold threaded formation integrative-structure, be provided with and regulating core bar external screw thread phase with regulation core bar length respective cavities inner wall position
Adaptive female thread.
The present invention has the advantage that compared with existing exterior fixation bracket
1. the present invention has simple in construction, cost is low, volume is little, fixation is reliable, operation sequence is convenient and simple
Advantage, is that one can complete to fix, pressurize, can realize again the multifunctional exterior fixing rack of the malformation correction to bone or prolongation.
2., because being provided with spicule in the two ends of semi-ring connecting rod and center the most simultaneously, its spicule is at 3 and stablizes
Structure, fixation is reliable.
3. malformation correction or the lengthening operation because to the malformation correction of bone or prolongation, only regulation handle need to be rotated, to bone
Program is very convenient simply.

Detailed description of the invention
By non-limiting example, the invention will be further described below in conjunction with the accompanying drawings.
A kind of exterior fixation bracket for bone lengthening as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of for Limb lengthening
The exterior fixation bracket of art, is mainly made up of semi-ring connecting rod, spicule, extender parts and support bar.Described semi-ring connecting rod is
Open pentagon shaped, be arranged two in parallel at upper-lower position.Support bar is at the two ends of semi-ring connecting rod center edge axially etc.
Distance be arranged two in parallel, and its two ends are fastenedly connected with semi-ring connecting rod by the fastening of bar bar respectively.In semi-ring connecting rod
Two ends and center are provided with spicule the most simultaneously, are fastenedly connected with semi-ring connecting rod by shank fastening respectively.
The main technical schemes that the present invention is taked is, described extender parts, by support bar, locking nut, regulate core bar
And regulation handle composition.Described regulation taper knob is contained on support bar, sets at the cavity position near first locking nut one end
There is female thread.It is respectively arranged with first external thread section and second suitable with regulating handle female thread at the two ends of regulation core bar
External thread section, described regulation core bar wear the first locking nut and its two ends of the second locking nut respectively with regulation handle and support
Bar is threaded.
Further technical scheme is that described support bar is cavity two sections combinative structure, by with regulation core bar two
Hold threaded formation integrative-structure, be provided with and regulating core bar external screw thread phase with regulation core bar length respective cavities inner wall position
Adaptive female thread.
The work process of bone lengthening: squeeze into 3 spicules at knochenbruch two ends respectively, by shank fixation clamp and semi-ring connecting rod
Fixing, connect two ends semi-ring connecting rod with extender parts, fix with bar bar fixation clamp.By rotating the regulation of extender parts
Handle makes to regulate core bar elongation, drives and is arranged on the regulation semi-ring connecting rod of handle end and spicule moves, by slow tractive
Make bone length increase, be finally reached the purpose of Limb lengthening.
In sum, the present invention has simple in construction, cost is low, volume is little, fixation is reliable, the convenient letter of operation sequence
