Description
Technical field
The utility model relates to intertrochanter fracture of femur and fracture of neck of femur operation device, in particular to a kind of femur are close
Kirschner wire fixation device is held, being fixed temporarily in intertrochanter fracture of femur art is currently used primarily in, is also applied for fracture of neck of femur.
Background technique
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 warp
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.Operation fixed in proximal femoral nail is carried out for intertrochanter fracture of femur, routine operation position leads 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), only perform the operation on non-orthopedic traction bed, and in the case where non-orthopedic traction bed, it is past in intertrochanter fracture of femur art
Toward will appear the case where being shifted after the reduction of the fracture again, it is therefore desirable to be fixed temporarily, be prevented to the fracture resetted with Kirschner wire
Only fracture redisplacement.If manually squeezing into Kirschner wire, Kirschner wire, which will appear, to be squeezed into pulp cavity or skids off from distal femoral surface, can be stopped in this way
The implantation of intramedullary nail (or steel plate) fails to fix two broken ends of fractured bone of fracture.Therefore it is required that the Kirschner wire being fixed temporarily guarantees through bone
Far and near two broken ends of fractured bone are rolled over, play the role of being fixed temporarily to the reduction of the fracture, guarantee the implantation that will not stop intramedullary nail (or steel plate) again,
In order to meet this two conditions, need to squeeze into Kirschner wire carry out positioning and guiding.
Currently, positioning of the Kirschner wire guide pin in neck of femur, is typically necessary using corresponding guider before neck of femur
Face is positioned with a Kirschner wire, then finally determines kirschner by the lower continuous adjustment of CB perspective in this, as the reference of top rake
The guide pin direction of needle and position.Using existing guider when progress Kirschner wire penetrates positioning, has the following deficiencies: and 1) be oriented to
Structure is complicated for device, inconvenient, and the operating time is long, increases anesthetic risks；2) wound is big, needs to cut proximal femur biggish
The tissue such as integumentary musculature, aggravates local tissue damage, destroys blood fortune, increases the pain of patient, suffers from particularly with Elder
Person increases operation wound, does not meet minimally invasive theory；3) Kirschner wire passes through pulp cavity, can stop the implantation of intramedullary nail (or steel plate).Cause
This, research and develop a structure it is simple, convenient for operation, and Kirschner wire squeezes into position suitable, can effectively fix two broken ends of fractured bone of fracture, maintenance
The reduction of the fracture, and will not influence the implantation of proximal femoral nail (or steel plate), can be realized minimally invasive, effectively improve operative effect
Near end of thighbone Kirschner wire fixation device be the utility model research purpose.
Utility model content
In view of the above-mentioned problems of the prior art, the utility model lies in that providing a kind of near end of thighbone Kirschner wire fixation dress
