Description
Technical field
The present invention relates to a kind of Limb lengthening external fixator, a kind of unilateral double-arm is particularly related to adjustable two-way double dynamical
Limb lengthening locking and pressurizing external fixator, Cranial defect, Limb lengthening and malformation correction for lower limb are treated, and belong to bone-specific drug apparatus skill
Art field.
Background technology
Extend pressuring locking type external fixator currently without the femur of the adjustable double-power bidirectional of unilateral double-arm, treatment femur is big
Section comminuted fracture, obstinate, bone fracture bone information, the treatment means of concurrent large segmental bone defect.Interior fixation or existing outer fixation
Limb lengthening (bone is moved) support is not applied to, and what obstinate had is up to 8 years, and pain is brought to patient, some requirement amputation, in order to
This problem is solved, fixed extension (bone is moved) support (as shown in figure 17), its master existed outside a kind of single armed occurs in the market
Have the disadvantage：1st, the physiology dissection for wearing slotted eye road and femur that steel nail fixes steel nail of design is not met, and the dissection of femur physiology is special
Putting is：The dissection of femur physiology is slight curved to lordosis, and femur long bone axis is arc (as shown in figure 11), and is designed
Single armed outside fixed extension (bone is moved) support, devise 3 pieces and wear steel nail folder steel nail slotted eye road, every piece can fix and select 2 steel
Slotted eye road is followed closely all on a horizontal line, the steel nail of several groups of nail clipping boards is fixed outside drift bolt to be all through on femur axis, femur
Proximally and distally can drift bolt on femur axis, and steel nail is then through on facies posterior femoris soft tissue in the middle of femur, or is through femur
Below in cortex of bone；2nd, nail clip block is without adjustability forward or backward, it is impossible to complete extension osteotomy (bone is moved).It is fixed outside single armed
The basic requirement of extension (bone is moved) support is all unable to reach, therefore is abandoned by orthopedics expert, not expanded.
Because single armed Limb lengthening support, design departs from the dissection of femur physiology, and femur has the slight arc to lordosis, nail clip groove
Hole is without adjustability, inapplicable lower limb big section of comminuted fracture of femur, obstinate, and the large segmental bone defect that bone information is caused can not
By effective method, patient's useless leg in tow, it is impossible to walk, bring long-term pain is having or even require amputation.Orthopaedics
Expert needs to recall again her ring support (Figure 18) clinical practice of asking love to invent, osteotomy of 100 Nian Qian Russia in order to clinical
Extended treatment Cranial defect, the open big section comminuted fracture Cranial defect of calf shank or treatment side Lower limb shortening, cyllopodia of walking, though
So it is fixed on 4-6 becket on shank, intersection wears draw point, and to fix extension osteotomy very heavy, takes up space big, postoperative carrying is not
It is convenient, but the therapeutic purposes of extension osteotomy repairing bone defect can be reached.
But big section of crushing sclerotin obstinate bone information of thigh femur is used in cause to fix not outside large segmental bone defect, ring type
It is applicable, because thigh anatomical features soft tissue is abundant, femoribus internus has main artery and vein, Sciatic nerve, the outer fixed branch of annular
Frame, intersection pin is worn to femur, and closure is passed from big leg outer side through femur from inside skin, and femoribus internus has compared with main artery, quiet
Arteries and veins, nerve, it is necessary to avoid blood vessel, several draw points intersect big leg outer side and penetrated, and through femur, skin danger close is passed from inner side,
Difficulty of threading a needle is big, runs into individual arteriovenous anatomical position variation, draw point wears out big blood vessel, can cause massive haemorrhage, particularly big
Extension osteotomy under the small tuberosity of leg femur, at thigh femoral greater trochanter position, close to the nearly groin position of pelvis, (femur ditch position has
Femoral artery and femoral vein, femoral nerve are all big blood vessels), it is impossible to it can only be fixed with loopful with semi-ring, two draw point vertical direction are worn
Low-angle intersects draw point (fixed not as loopful intersect fixation of threading a needle stable), and outer fixation wears intersection pin and can cause to wear out femoribus internus
Neurovascular danger, carries the several beckets of thigh after outer fixation and semi-ring takes up space greatly, sitting and lying all effected is near in thigh
End semi-ring is unable to wide-angle and wears draw point, therefore fixation is not stable, and therapeutic effect is unreliable, therefore inapplicable.
