Abstract
The utility model discloses an external fixator for bone lengthening. The external fixator mainly comprises two semi-ring connecting rods, bone pins, lengthener components and supporting rods, wherein the two semi-ring connecting rods are arranged in parallel in upper and lower positions, two supporting rods are axially arranged at two ends of central edges of the semi-ring connecting rods at equal intervals, and two ends of the supporting rods are in fastening connection with the semi-ring connecting rods through rod-rod fastening clips; the bone pins are arranged at two ends and central positions of the semi-ring connecting rods respectively and in fastening connection with the semi-ring connecting rods through pin-rod fastening clips; and each lengthener component consists of the supporting rods, locking nuts, an adjusting core bar and an adjusting handle. The external fixator has the advantages of simple structure, low cost, small size, firmness and reliability in fixation, and convenience and simplicity in operation procedure. By means of the multifunctional external fixator, the fixation and pressurization can be completed, and the malformation correction or lengthening of bones can also be realized.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to
a kind of exterior fixation bracket for bone lengthening.
Background technology
Exterior fixation bracket is that the draw point by interting in bone is connected with device outside and fixes, and bone is imposed to axial pressure, traction (limbs or bone transport).That current clinical orthopaedics is at the most frequently used operation method for the treatment of long bone fracture and malformation correction.In prior art, exterior fixation bracket has monolateral exterior fixation bracket, hook groove exterior fixation bracket, ring external fixation support.Its Main Function, all for severed limb being fixed and pressurizeing, prevents that knochenbruch from reversing and distortion, to promote the healing of fracture, but can not realize the therapeutical effect to the malformation correction of bone or prolongation.
Summary of the invention
The purpose of this utility model is to overcome existing
exterior fixation bracketdeficiency in technology, provide "
a kind of exterior fixation bracket for bone lengthening".The utlity model has simple in structure, cost is low, volume is little,
fixingthe advantage solid and reliable, operation sequence is convenient and simple, is a kind ofly can complete fixing, pressurization, can realize again multi-functional to the malformation correction of bone or prolongation
exterior fixation bracket.
For achieving the above object, technical solution adopted in the utility model is:
for an exterior fixation bracket for bone lengthening, mainly bysemi-ring connecting rod, spicule, extender parts and support bar form.Described semi-ring connecting rod is open pentagon shaped, at upper-lower position, be arranged two in parallel.Support bar be arranged two in the two end axles of semi-ring connecting rod center edge in parallel to equidistant, and its two ends are fastenedly connected by bar bar Jin Gu Clip and semi-ring connecting rod respectively.Two ends and center at semi-ring connecting rod are provided with respectively spicule simultaneously, are fastenedly connected respectively by shank Jin Gu Clip and semi-ring connecting rod.
The main technical schemes that this utility model is taked is, described extender parts are by support bar, and locking nut, regulates core bar and regulating handle to form.Described regulating handle is sleeved on support bar, in the inner chamber position near first locking nut one end, is provided with female thread.Regulating the two ends of core bar to be respectively arranged with first external thread section suitable with regulating handle female thread and the second external thread section, described adjusting core bar Consistent wears the first locking nut and its two ends of the second locking nut are threaded with regulating handle and support bar respectively.
furthertechnical scheme is that described support bar is cavity two sections combinative structurees, by the formation integrative-structure that is threaded with adjusting core bar two ends, is being provided with the female thread suitable with regulating core bar external screw thread with regulating core bar length respective cavities inner wall position.
This utility model and existing
exterior fixation bracketcomparing tool has the following advantages:
1. the utlity model has simple in structure, cost is low, volume is little,
fixingthe advantage solid and reliable, operation sequence is convenient and simple, is a kind ofly can complete fixing, pressurization, can realize again multi-functional to the malformation correction of bone or prolongation
exterior fixation bracket.
2. because the two ends at semi-ring connecting rod and center are provided with respectively spicule simultaneously, its spicule is 3 points
rock-steady structure, fixingsolid and reliable.
3. because of to the malformation correction of bone or prolongation, only need rotation regulating handle, very convenient simple to the malformation correction of bone or lengthening operation sequence.

The specific embodiment
Below in conjunction with accompanying drawing, by non-limiting example, the utility model is described in further detail.
a kind of exterior fixation bracket for bone lengtheningas shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5,
for an exterior fixation bracket for bone lengthening, mainly bysemi-ring connecting rod, spicule, extender parts and support bar form.Described semi-ring connecting rod is open pentagon shaped, at upper-lower position, be arranged two in parallel.Support bar be arranged two in the two end axles of semi-ring connecting rod center edge in parallel to equidistant, and its two ends are fastenedly connected by bar bar Jin Gu Clip and semi-ring connecting rod respectively.Two ends and center at semi-ring connecting rod are provided with respectively spicule simultaneously, are fastenedly connected respectively by shank Jin Gu Clip and semi-ring connecting rod.
The main technical schemes that this utility model is taked is, described extender parts are by support bar, and locking nut, regulates core bar and regulating handle to form.Described regulating handle is sleeved on support bar, in the inner chamber position near first locking nut one end, is provided with female thread.Regulating the two ends of core bar to be respectively arranged with first external thread section suitable with regulating handle female thread and the second external thread section, described adjusting core bar Consistent wears the first locking nut and its two ends of the second locking nut are threaded with regulating handle and support bar respectively.
furthertechnical scheme is that described support bar is cavity two sections combinative structurees, by the formation integrative-structure that is threaded with adjusting core bar two ends, is being provided with the female thread suitable with regulating core bar external screw thread with regulating core bar length respective cavities inner wall position.
bone lengtheningwork process: squeeze into respectively 3 spicules at knochenbruch two ends, fix with shank fixation clamp and semi-ring connecting rod, connect two ends semi-ring connecting rod with extender parts, fix with bar bar fixation clamp.By rotating the regulating handle of extender parts, make to regulate core bar to extend, drive the semi-ring connecting rod and the spicule that are arranged on regulating handle end to move, by slow tractive, bone length is increased, finally reach the object that bone extends.
