Description
Technical field
The present invention relates to a kind of medicine equipment, more particularly to a kind of screw broken nail device for fetching nail.
Background technology
After fracture and injury occurs, it usually needs in fracture drivescrew, to aid in knochenbruch to heal.However, when fracture
When the time of healing is longer, the fatigue strength of screw reaches capacity, when now doctor takes screw, the easy feather plucking of screw or disconnected
Split, or even screw has occurred and that fracture before nail is taken.After screw feather plucking or fracture, medical worker stills need to take out screw.Pass
The side of the taking-up feather plucking of system or the screw of fracture mainly has two kinds:
First, being polishing to trepan along screw length direction by bone mill thoroughly, screw is further taken out, this method is needed along spiral shell
The direction for following closely length grinds whole bone thoroughly, and the operating time is long and the injury to caused by bone is big, or even second fracture etc. occurs
Situation.
Second, first polished inwards along screw a segment distance from the opening of screw with trepan, then will with instruments such as pliers
Screw screws out, and the direction that this method needs not be along screw length grinds whole bone thoroughly, need to only be beaten along the length direction of screw
The distance for pliers crawl screw is ground, is polished yet with needing to stretch on pliers in hole, therefore hole of polishing needs to beat
That grinds is very big, is injured greatly to caused by bone, and when screw and bone are completely embedded, the clamping force of operating personnel's offer is not
Foot, pliers will be difficult to screw out screw.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to provide a kind of screw broken nail device for fetching nail, taking
During screw, the only trepan that need to be ground along screw length direction to the bone around screw and can be along screw length
Device for fetching nail in bone is stretched into direction, and is tightened, there is provided clamping force, then screws out screw.
To achieve the above object, the invention provides following technical scheme:A kind of screw broken nail device for fetching nail, its feature exist
