Description
Technical field
The present invention relates to intertrochanter fracture of femurs and fracture of neck of femur operation device, in particular to a kind of near end of thighbone gram
Family name's needle fixation device is currently used primarily in being fixed temporarily in intertrochanter fracture of femur art, is also applied for fracture of neck of femur.
Background technology
With social astogeny, Treatment of Intertrochanteric Fractures in Aged Patients increases year by year.Elderly patients are associated with a kind of or more more
Kind internal disease, it is poor to the tolerance of operation, it needs to take modus operandi minimally invasive, that damage is small as far as possible.Closed reduction passes through
It is a kind of Minimally Invasive Surgery that skin, which is inserted into fixation in the anti-rotation intramedullary nail of near end of thighbone, is the master of current treatment Procedure on Intertrochanteric Fracture in Aged
Want method.Fixed operation in proximal femoral nail is carried out for intertrochanter fracture of femur, routine operation position is led for orthopaedics
Draw dorsal position on bed, but in clinical practice, (basic hospital lacks orthopaedics and leads since the corresponding hardware facility of operating room is not perfect
Draw bed), it only performs the operation on non-orthopedic traction bed and in the case of non-orthopedic traction bed, it is past in intertrochanter fracture of femur art
Toward will appear situation about being shifted again after the reduction of the fracture, it is therefore desirable to the fracture resetted is fixed temporarily with Kirschner wire, prevented
Only fracture redisplacement.If manually squeezing into Kirschner wire, Kirschner wire, which will appear, to be squeezed into pulp cavity or is skidded off from distal femoral surface, can be stopped in this way
Intramedullary nail（Or steel plate）Implantation or fail fix two broken ends of fractured bone of fracture.Therefore it is required that the Kirschner wire being fixed temporarily ensures through bone
Far and near two broken ends of fractured bone of folding, play the role of being fixed temporarily to the reduction of the fracture, ensure to stop intramedullary nail again（Or steel plate）Implantation,
In order to meet this two conditions, need to squeeze into Kirschner wire carry out positioning and guiding.
At present, Kirschner wire guide pin is typically necessary using corresponding guider before neck of femur in the positioning of neck of femur
Face is positioned with a Kirschner wire, then the reference in this, as top rake, by the lower continuous adjustment of CB perspectives, finally determines kirschner
The guide pin direction of needle and position.Using existing guider when progress Kirschner wire penetrates positioning, there are following defects：1）It is oriented to
Device is complicated, inconvenient, and the operating time is long, increases anesthetic risks； 2）Wound is big, needs incision proximal femur larger
The tissues such as integumentary musculature aggravate local tissue damage, destroy blood fortune, increase the pain of patient, suffer from particularly with Elder
Person increases operation wound, does not meet minimally invasive theory；3）Kirschner wire passes through pulp cavity, can stop intramedullary nail（Or steel plate）Implantation.Cause
This, research and development are a simple in structure, easy to operation, and Kirschner wire squeezes into position suitable, can effectively fix two broken ends of fractured bone of fracture, maintain
The reduction of the fracture, and do not interfere with proximal femoral nail（Or steel plate）Implantation, can realize minimally invasive, effectively improve operative effect
Near end of thighbone Kirschner wire fixation device be the present invention research purpose.
Invention content
