Description
Technical field
The present invention relates to a kind of operating theater instruments, relate in particular to a kind of interlocking intramedullary nail pinning location drilling method and apparatus.
Background technology
At present, adopt the interlocking intramedullary nail fixation for treatment comparatively general for tubular bone fracture both at home and abroad, it has fixation, avoid fracturing axially and the generation of rotation deformity.But because interlocking intramedullary nail is subject to affecting its insertion end and can deforming of key physiologic radian when implanting the skeleton pulp cavity, so just, produce self-locking nail aiming hard problem, more common intramedullary pin point technique roughly has three kinds at present: with upper nail technology under the spacing point technique of locating rod, the free-hand X-ray examination and magnetic force location point technique, all there is defective in these three kinds of technology, and common trait is for locating from outside to inside interlocking intramedullary nail pinning nail hole outside skeleton.
The spacing point technique of locating rod: the sighting bar of existing intramedullary nail sighting device is fixed, and causes the position of its placed channel also to be fixed, and it only could accurately be located when intramedullary pin is not out of shape.Therefore, in the situation that intramedullary pin deforms, the spacing point technique of locating rod is difficult to accurately location.
Upper nail technology under the free-hand X-ray examination: the doctor need to continue to use x-ray to look for lock hole at osseous tissue, and its shortcoming continues to use x-ray, produces a large amount of radiation, and degree of accuracy is not high, brings expendable injury for doctor and patient.
Magnetic force location point technique needs to do otch in the pinning approximate location in advance, and to fully cut, peel off the soft tissues such as the outer muscle of periosteum, fascia, not so being easy to that generation is passed in the aiming of sleeve disturbs, detector also must be close to cortical bone, otherwise the induction of magnetic force can be influenced, and used detection magnetic piece small volume will be responded to inefficacy when facing than large deformation, cause sighting device to lose efficacy.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists, break existing traditional mode of outside skeleton, locating from outside to inside the interlocking intramedullary nail lockhole, a kind of method and device of the brand-new location of holing from inside to outside outside skeleton in the interlocking intramedullary nail pinning nail hole are provided, simple to operate, registration, quick.
