Description
Technical field
The present invention relates to machinery fields, and in particular to the navigation device of the lock hole of intramedullary nail and is configured with navigation device
Intramedullary nail system.
Background technique
Intramedullary nail internal fixation as treatment Fracture internal fixaiion effective means, be widely used, development and production with
Matched intramedullary nail instrument can promote the development of Minimally Invasive Surgery, restore human physiological functions, have in field of orthopaedics wide
Market prospects.Every class intramedullary nail instrument includes intramedullary nail and aiming locating apparatus corresponding with intramedullary nail and general surgical device
Tool, these instruments constitute an intramedullary nail positioning system.
Currently, often to use Intramedullary nailing fracture site when treating tubular bone fracture patient, i.e., inserted in intramedullary nail
After entering bone cavity, lock hole is bored on bone tissue, then bone tissue and intramedullary nail are fixed together with pinning, in general,
After longer intramedullary nail implantation bone cavity, because individual physiologic radian is variant, the position in intra medullary nail far-end locking hole how is realized
Aiming is a technical problem, now more common intramedullary nail point technique substantially there are three types of：It is aimed at the limit of locating rod
Technology, manually upper nail technology and magnetic force positioning point technique, and these three technologies all existing defects.
The limit point technique of locating rod：The aiming body of rod of existing intramedullary nail sighting device be it is fixed, cause thereon
Positioning through hole position be also it is fixed, it can only be corresponding with the lockhole position on the intramedullary nail for not having deformation in ideal,
Therefore, in the case where intramedullary nail deforms, the lock hole and bone cavity internal medullary mass that are drilled out on bone tissue by the positioning through hole
The lockhole position inside nailed on does not correspond to, it is therefore desirable to skin incision is done on bone tissue, then bore one with lock hole is in 90 ° substantially
The location hole of angle, then locating rod insertion positioning hole is resisted into intramedullary nail, by promoting locating rod that will correct the marrow of deformation
Interior nail needs drill two holes, patient on bone tissue that must not be not subject to additional Iatrogenic injury, the behaviour of operation using the technology
Make step also versus busy, in addition to this, if the deformation direction of intramedullary nail is not the direction of insertion of locating rod, locating rod is just not
The deformation of intramedullary nail can be effectively corrected, sighting device is also by whole misalignment.
Manually upper nail technology：Doctor needs persistently to look for hole location on bone tissue using X-ray, and persistently will using X-ray
A large amount of radiation are generated, to bring unnecessary radiohazard to doctor and patient, simultaneously experience of this technology to doctor
It is required that also very high.
Magnetic force positions point technique：It needs to do notch in distal locking nail Position Approximate in advance, and sufficiently to cut, remove
Not so the soft tissues such as bony tissue outside fascia and muscle are easy to the passage of the aiming to sleeve and drill bushing and generate interference, detector
Surrounding must also be far from ferromagnetic instrument, and otherwise the induction of magnetic force can be impacted, or even can incude failure, leads to sighting device
Whole misalignment.
