Description
Technical field
It is particularly a kind of to stop nail positioner the present invention relates to orthopaedic trauma medical instruments field.
Background technology
Intramedullary nail is the standard method for treating most of long bone setting board of skeleton end fracture, can retain periosteum blood supply, it is allowed to axially negative
Lotus, soft tissue is disturbed small.But during using intramedullary interlocking nail setting board of skeleton end fracture, it is commonly present fracture-angle abnormality and unstable
The problem of.Its reason mainly has following 2 aspects：1. distal tibial pulp cavity is roomy, intramedullary nail is difficult to contact with cortex of bone, in marrow
Nail is difficult to the center for being placed on pulp cavity；2. conventional intramedullary interlocking nail distal end pinning is mostly placed in parallel for coronal-plane at present, in marrow
Hunt effect can occur between interior main nail and pinning, along with the traction action of muscle, so as to influence to maintain the reduction of the fracture and consolidate
Fixed reliability.And stop putting people and can reducing the width of distal tibial pulp cavity for nail, make the preferable marrow for meeting that self-locking nail is fixed
Chamber increases implants and the rigidity and intensity of bone structure, increases the action length of intramedullary nail, and establish to distally being extended
Key isthmus, stop nail and the three-point mount of intramedullary nail end, meanwhile, pulp cavity diminishes, and the stress on pinning also accordingly diminishes, from
And hunt effect can be effectively prevented, reduce the generation of broken nail.It is theoretical according to acute angle, stop that nail is generally placed upon the recessed of angulation
Side, i.e., apart from fracture line with remote 1cm, pulp cavity center line 6-7mm puts position stop nail, but during actually nail is put, due to skin
Exist Deng soft tissue, and with different degrees of damage, swelling, displacement fracture, nail site is put it is difficult to be accurately positioned in addition.At present
Device clinically there is no to assist to stop ground precise positioning.
