Dynamic position.
The present invention is directed to the patient of femoral bone tuberosity () portion fracture, is treated using cutting operation, bleeding, traumatic easily occurs
Situations such as multiple organ interferes, controls using tcm characteristic is minimally invasive, theoretical by gradient flexible fastening, and stable triangular is theoretical, anti-rotational
Fixation principle, bracket length adjustable maintain outrigger tension principle, solve previous hip external fixator because unstable, cause
Femoral neck shaft angle lose, top rake is lost, there is the problem of coxa vara deformity, and for the trouble that femoral bone tuberosity () portion fractures
After the previous senile osteoporosis of person is fixed, only rigidly fix, the problem of nonelastic pressurization, the present invention is not only solved
Elastic pressurized problem, and a possibility that improve union rate and reduce bed rest time long and lead to complication.
The present invention proposes that " two precisely, two parallel " are theoretical, it may be assumed that
Two precisely: the accurately region of anatomy, accurate inserting needle (inserting needle of proximal femoral neck maintenance hexagonal angle degree).
Two parallel: proximal end sliding slot (i.e. long through-hole) is parallel with thigh lateral, the pressurization adjustment portion of distal end after proximal end is fixed
Divide (i.e. lead screw) parallel with thigh middle and lower sections.
The present invention has the feature that
6.5 ° of angles 1. the opposite first support 1 of design second support 2 is turned up, with lasting maintenance lateral side of femur pressing tension, dynamic is tieed up
Hold femoral neck shaft angle；
2. adjustable (lead screw) is designed, and by the way of first extending and pressurizeing afterwards, adjustment length needs to determine according to actual therapeutic,
The adjustability of sliding rack 8 is increased, graduated scale is convenient for accurate adjustment size.
3. the design (i.e. tooth design) of anti-revolved clamp block, can stablize the bone fixation needle at far and near end, and then limit fixed pin
In the tired fine motion for the treatment of plane；
4. outer solid rod is used in 6.5 degree of EEF bogie (place that stress is concentrated, the i.e. interconnecting piece of first support 1 and guiding axis 22)
Integrated molding design, effectively prevent being broken herein in use process；
5. the thickness of fixed pin selects Φ 4mm or Φ 5mm, to generate the elasticity of fixed pin, product material selects flexibility requirements
Height, elastic membrane amount are big, and fixed pin front end uses unidirectional Design of Screw Thread, can the effectively anti-withdraw of the needle；
6. the sharp keen design of needle point trigone, can rapidly enter cortical bone, the damage of periosteum is reduced, prevents from sliding at bone face.Inserting needle
Angle requirement: two pieces of proximal end needle, one piece enters in parallel along neck of femur tension lines, and another piece enters in parallel along bone stock pressure line, produces
Raw two needle bodies and lateral side of femur are in the stabilization fixed structure of " triangle ", can anti-needle is sliding moves back or enter abdomen depths, later period elasticity adds
After pressure, the continuous elastic that fracture proximal end generates up and out can be fixed, prevent coxa vara；
7. the parallel of two pieces of distal end needle enters in distal femur bone, bone mass is good herein, and holding strength is stronger, beats for flexible fastening
Lower basis.
The present invention is outer using minimally invasive exterior fixing rack elasticity treatment intertrochanteric fracture of the femur and children and youth neck of femur
It is fixed, wound, bleeding and other risks of patient are reduced, the incidence of coxa vara deformity and phlebothrombosis is reduced, improves fracture
Healing rate makes patient leave the bed ahead of time, and easy to operate, application easy to spread.
The fixation of the universal fixture block (i.e. supporting block 24) in present invention distal end not only facilitates medical worker to operate, but also can be substantially
Degree ground shortens operating time and healing time, reduces wound, bleeding and other risks of patient, and patient is made to leave the bed ahead of time；
Pressurization screw rod in distal end (makes to generate relative displacement between sliding rack 8 and lead screw 23 by rotational lead screw 23, since sliding rack 8 is with the
Two fixed pins 9 are fixed on bone, are just produced the mobile effect of setting lead screw 23 at this time, are moved to pull on or press by lead screw 23
Tight first support 1 generates pressure to the first fixed pin 6 being fixed in first support 1) can produce proximal end fixed pin upwards, to
Outer elastic prying and pulling power, the fixed pin of proximal end two and femoral shaft form stable triangular, are embedded in cunning in conjunction with the protrusion rectangle of fixture block
Slot keeps fixed pin and outer fixed link position more stable, can reduce the generation of hip deformity, improve the survival rate of patient, fracture is cured
Conjunction rate；In addition, this fixed form can operate under local anaesthesia, reduction general anesthesia or the hard outer risk anaesthetized are advanced ages, basic sick more
Intertrochanteric fracture of the femur patient Gospel.
The embodiment of the present invention is explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Example, within the knowledge of a person skilled in the art, can also make without departing from the purpose of the present invention
Various change out.
