Description
Technical field
The invention belongs to a kind of fracture auxiliary reset devices, are specifically related to a kind of femur auxiliary reset device.
Background technique
For femoral fracture operation, it is also key point that quickly and accurately reset, which is the difficult point entirely performed the operation, due to
Femoral shortening, rotation displacement are obvious after the fracture that powerful myotasis makes around femur, and femur is circular crown tubular bone, middle section
No obvious bone label will overcome powerful muscle to draw in art and be accurately positioned by no means easy, often make the reduction of the fracture in art anti-
It is multiple, local soft tissue damage is aggravated, fracture surgery delayed union or disunion are often resulted in.
Currently, being used for femoral fracture operative reduction device, patient is helped to eliminate traction problems in art to a certain extent,
Operating time is greatly saved, reduces operating difficulty, but often occurs rotating after resetting and shortened deformity, lacks multiple to femur
The effect of position calibration, reset is often relied on macroscopic view feeling and patient's surgical experience judges, and lacks and clearly judge that femur revolves
Turn the objective reference of the line of force, subjectivity is too strong, and leading to postoperative more patient, there are femoral rotation deformities.It is comminuted in practical femur
Fracture case in, it is postoperative rotate, shortened deformity the case where it is even more common, and at present repositioning method mostly be combine art in X
Transmission and complicated calculations or dependence subjective vision judgement are resetted, but there are larger reset error, complicated calculating
The poor operability in actual clinical surgical procedure, the hair that subjective vision judgement frequently results in postoperative rotation and shortened deformity resets
It is raw.And art can easily be helped very much by resetting all kinds of self-control tractors and robot restorer in common femoral fracture art in art
Femoral fracture in person's reduction, but almost all of outer tractor and most robot reset systems do not have at present
To the objective and accurate correcting function of rotation and cripetura, and robot resetting apparatus requires high, connection complexity to medical environment, no
Preferably promote the use of, therefore, it is a can with simple operations and be suitble to practical the resets demand of clinical operation, and have to fracture rotate,
The correcting function of shortened deformity resets the equipment of standard to meet femur to be the urgent demand in market.
