Description
Technical field
The utility model relates to medical instrument applied technical field more particularly to a kind of bodies of intramedullary interlocking nail distal end pinning
Outer fluoremeter.
Background technique
Limbs fracture has been widely used cross locking marrow nail on Orthopedic Clinical, is mainly used for treatment of fractures of femur shaft in adults.But it performs the operation
Often there is distal locking nail failure, according to the literature, the success rate of femur sighting device pinning for the first time is only 36%, and tibial intramedullary nailing is taken aim at
Pinning success rate is 65% to quasi- device for the first time.In case of pinning fails in art, patient can use pinning technology unarmed under C arm machine, Huo Zhekuo
Lower pinning is looked in big skin incision and drilling straight.The iatrogenic injury of x-ray radioactive damage and patient when can so cause to perform the operation,
Especially in basic hospital, some is finally changed to Plate internal fixiation.
Currently, the locator remote stomidium positioning of the intramedullary interlocking nail distal end pinning of clinical use owes accurate, main cause is
Intramedullary nail swings and changes at a distance from master positioning bar in art, prevents locating rod from accurately withstanding on intramedullary nail, causes
Location hole on locking of intramedullary nail and master positioning bar, so that drilling be caused to fail, need to be changed into again under X-ray and be bored not in same plane
Hole both extends operating time, increases operating difficulty, also will affect surgical effect.But it finds, distal locking nail is carried out quasi- in use
Really implantation is a difficult point, is exactly using with high-precision import instrument, there is also same problem, reason is: because of stock
Bone distal end shape is not square, and has slope, so, if slightly exerted oneself, drill bit will be suitable when carrying out positioning drilling
It glides along slope, contact can not be positioned with marrow bone nail distal locking nail by eventually leading to locating rod, and distal locking nail location hole can be made downward
Displacement；Expansion marrow size in operation is often mismatched with the diameter of intramedullary nail, after the bone holding forcep that fracture end is reset are fixed, is inserted
It meets obstructions when entering intramedullary nail big, the result being driven into simply often deforms intramedullary nail, and lockhole position is caused to deviate；For
The folding of distal part of femur bone, because intramedullary nail is relatively thin, and distal end pulp cavity is larger, and there may be shakings for intra medullary nail far-end；When in marrow
After first piece of lockhole of nail insertion pulp cavity is drilled, during exiting drill bit, because of the slight movement of fracture site, pinning is brought
Into hole difficulty, have to redrilling, repeatedly drilling make bone hole road expand, influence to fix.Sum up this various reason, core
It is to design the three-dimensional localization of distal lock hole of intramedullary nail with lock to produce deviation, until looking for inaccurate marrow when locating rod being made to be inserted into bone cavity
Interior nail distal end locating platform.So to complete entirely to perform the operation, it have to be accurately positioned using C-arm, be carried out using unarmed pointed cone method
It places, as a result, operating time extends, patient's bleeding increases, and patient and the patient exposure duration under x-ray are long and are hurt
It increases.
In conclusion how to design it is a make distal lockhole realize quickly and precise positioning intramedullary interlocking nail distal end
The locator of pinning is one of those skilled in the art's technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model be for above-mentioned state of the art and provide one kind can make distal end
Lockhole realizes quick and the intramedullary interlocking nail distal end pinning of precise positioning external fluoremeter, guarantees the remote of intramedullary nail with lock
End pinning is satisfactorily implanted fixation, avoids unnecessary damage, practical, reduces the pain of patient, and can reduce medical matters people
The working strength of member.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of intramedullary interlocking nail distal end pinning
External fluoremeter, including handle, locating rod and cross locking marrow nail；It is characterized by: the outer end of the cross locking marrow nail with
The handle, at its lower end is detachable to be fixed together；Locating rod activity is threaded through the upper end of handle and the sliding of energy front and back, and locating rod
It is fixed together between handle by adjustable locking structure, the fine tuning to press skin is offered in the middle part of locating rod
Screw hole, trimming bolt is provided in the fine tuning screw hole, and the front end of locating rod is equipped with distal end locating rack, opens up on the locating rack of distal end
