Abstract
The invention discloses an external fixation support for bone lengthening, which mainly comprises semicircular connecting rods, bone needles, lengthener components and support rods, wherein the two semicircular connecting rods are shaped like an open pentagon and arranged up and down in parallel; the two support rods are equidistantly arranged in parallel at the ends of the central edges of the semicircular connecting rods in the axial direction; the ends of the support rods are in fastened connection with the semicircular connecting rods via rod-rod fastening clips respectively; the bone needles are simultaneously arranged at the ends and the central positions of the semicircular connecting rods respectively; the bone needles are in fastened connection with the semicircular connecting rods via needle-rod fastening clips respectively; and the lengthener components comprise the support rods, locking nuts, adjusting core rods and adjusting handles. The external fixation support has the advantages of simple structure, low manufacturing cost, small size, firmness and reliability in fixation and convenient and simple operational program, and is a multifunctional external fixation support that can fulfill fixation and pressurization and also can realize malformation correction or lengthening of bones.
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 that the draw point by interting in bone is connected with device outside and fixes, and imposes axial pressure, traction (limbs or bone transport) to bone.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 being fixed severed limb and pressurizeing, prevents knochenbruch from reversing and distortion, to promote the healing of fracture, but the therapeutical effect of the malformation correction that can not realize bone or prolongation.
Summary of the invention
The object of the invention is to overcome existing
exterior fixation bracketdeficiency in technology, provide "
a kind of exterior fixation bracket for bone lengthening".The present invention has that structure is simple, cost is low, volume is little,
fixingthe advantage that solid and reliable, operation sequence is convenient and simple, is that one can complete fixing, pressurization, can realizes again the malformation correction of bone or the multi-functional of prolongation
exterior fixation bracket.
For achieving the above object, the technical solution used in the present invention is:
for an exterior fixation bracket for bone lengthening, primarily ofsemi-ring connecting rod, spicule, extender parts and support bar form.Described semi-ring connecting rod is open pentagon shaped, be arranged two in parallel at upper-lower position.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 respectively by bar bar Jin Gu Clip and semi-ring connecting rod.Be provided with spicule respectively in the two ends of semi-ring connecting rod and center simultaneously, be fastenedly connected respectively by shank Jin Gu Clip and semi-ring connecting rod.
The main technical schemes that the present invention takes is, described extender parts are by support bar, and locking nut, regulates core bar and regulating handle composition.Described regulating handle is sleeved on support bar, is provided with female thread at the cavity position near first locking nut one end.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 adjustment 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, described support bar is cavity two sections combinative structurees, by the formation integrative-structure that is threaded with adjustment core bar two ends, is being provided with the female thread suitable with regulating core bar external screw thread with adjustment core bar length respective cavities inner wall position.
The present invention and existing
exterior fixation bracketcompare tool to have the following advantages:
1. the present invention have that structure is simple, cost is low, volume is little,
fixingthe advantage that solid and reliable, operation sequence is convenient and simple, is that one can complete fixing, pressurization, can realizes again the malformation correction of bone or the multi-functional of prolongation
exterior fixation bracket.
2., because being provided with spicule respectively in the two ends of semi-ring connecting rod and center 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 rotate regulating handle, to the malformation correction of bone or lengthening operation sequence simply very convenient.Accompanying drawing explanation

Detailed description of the invention
Below in conjunction with accompanying drawing, by non-limiting example, the invention will be further described.
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, primarily ofsemi-ring connecting rod, spicule, extender parts and support bar form.Described semi-ring connecting rod is open pentagon shaped, be arranged two in parallel at upper-lower position.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 respectively by bar bar Jin Gu Clip and semi-ring connecting rod.Be provided with spicule respectively in the two ends of semi-ring connecting rod and center simultaneously, be fastenedly connected respectively by shank Jin Gu Clip and semi-ring connecting rod.
The main technical schemes that the present invention takes is, described extender parts are by support bar, and locking nut, regulates core bar and regulating handle composition.Described regulating handle is sleeved on support bar, is provided with female thread at the cavity position near first locking nut one end.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 adjustment 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, described support bar is cavity two sections combinative structurees, by the formation integrative-structure that is threaded with adjustment core bar two ends, is being provided with the female thread suitable with regulating core bar external screw thread with adjustment core bar length respective cavities inner wall position.
bone lengtheningwork process: squeeze into 3 spicules at knochenbruch two ends respectively, fixes with shank fixation clamp and semi-ring connecting rod, connects two ends semi-ring connecting rod with extender parts, fixes with bar bar fixation clamp.Make to regulate core bar to extend by the regulating handle rotating extender parts, drive the semi-ring connecting rod that is arranged on regulating handle end and spicule to move, by slow tractive, bone length is increased, finally reach the object of Limb lengthening.
