Technical field
The present invention relates to clinical synthetism technical field of medical instruments, particularly relate to a kind of auxiliary instrument that the intra medullary nail far-end pinning is installed when in bone surgery, implanting intramedullary pin.
Background technology
At present, when treatment tubulose fracture patient, technique for fixing is used widely clinically in the intramedullary nail with lock, and the installation of intra medullary nail far-end pinning is the key link of this technology, and the order of accuarcy of location, intra medullary nail far-end nail hole site directly affects operating difficulty and operation quality.The intra medullary nail far-end of commonly using is clinically now followed closely aiming location, hole site and is mainly contained following several mode: the one, and lasting by x-ray image documentation equipment searching position, hole in the operation, this technology not only requires high to doctor's operating experience, and the X-ray line can produce a large amount of radiation, and medical worker and patient are damaged.The 2nd, the spacing point technique of employing locating rod, the patent No. that relatively typically designs such as the inventor is 02267978.2 " far-end nail-hole positioning device of intramedullary-nail ", its construction features is to install one additional at locating rod to limit the stopping means that intramedullary pin swings, although played certain aiming function, but need to increase a boring at osseous tissue, not only operating procedure is many, and returning the patient increases extra wound.The 3rd, adopt magnetic force aiming location technology, relatively typically the patent No. such as inventor's design is 200420039024.X " automatic indicator for aiming far end pinhole of intramedullary nail with block ", its construction features is that magnetic force aiming indicator is installed in the locating hole on adjustable locating rod, cooperate the aiming location with the probe with Magnet in being inserted into intramedullary pin, this technology has improved the accuracy of lock intramedullary nail far-end nail hole aiming, but its deficiency is to need to remember in advance pointer position before the art, need observe at any time pointer position in the operating process, thereby very inconvenient, also easily go wrong, boring procedure can not Real Time Monitoring, the drill bit displacement can not in time be found, easily causes holing unsuccessfully.The patent No. is that 200910025314.6 " medical magnetic navigation spotter " and the patent No. are that 201020670499.4 " electronic navigation type intramedullary nail far-end aiming device " is although realized electronical display, and can carry out Real-Time Monitoring in the operating process, but its complex structure, cost of manufacture is high, is not easy to clinical expansion and uses.
Summary of the invention
Purpose of the present invention is exactly the defective that will overcome prior art, provides a kind of simple in structure, flexible and convenient operation, and the aiming accurate positioning also can aim at monitor controller in the intramedullary nail with lock far-end nail hole of carrying out Real Time Monitoring in the drilling operation process.
For achieving the above object, monitor controller is aimed at by the following technical solutions in intramedullary nail with lock far-end nail of the present invention hole: it comprises a magnetic force sight, the magnetic force sight has the positioning pipe of front end closed rear end opening, by hinge the aiming pointer is installed in the positioning pipe, the front end of aiming pointer is equipped with Magnet, in magnetic force sight rear end electronic monitor is installed, the upper end of electronic monitor housing is equipped with Intermediate Gray forked standard jaggy, the light-operated switch of controlling the electronic monitor sound and light alarm for signal input is installed in forked standard, and the rear end of aiming pointer is stretched in the breach of forked standard.
Above-mentioned intramedullary nail with lock far-end nail hole aiming monitor controller, one side of its electronic monitor housing is fixed with the adjusting bearing,, be equipped with and promote the adjusting bolt that sliding panel moves up and down regulating bearing with being inserted into the sliding panel of regulating on the bearing in the rear end of positioning pipe.Housing at electronic monitor is equipped with display lamp and/or buzzer and on and off switch.
Above-mentioned intramedullary nail with lock far-end nail hole aiming monitor controller, its circuit part that is installed in the electronic monitor in the housing comprises a 89T2051 single-chip microcomputer and the photelectric receiver for detection of the pointer position that is connected with this single-chip microcomputer, the oscillating circuit that clock signal is provided, reset circuit and light emitting diode and buzzer in order to report to the police.
The present invention passes through improvements over the prior art, avoided the radiation of X-ray, aiming can be carried out acousto-optic hint behind the location, does not have the collimation error, and is more convenient to operate, improved pointing accuracy, and can carry out Real Time Monitoring to whole boring procedure, avoid drill bit to depart from the nail hole site, make since aiming degree not the Gao Erxu probability of repeatedly holing be reduced to zero, thereby the shortening operating time alleviates patient's misery.And simple in structure, cost of manufacture is low, is particularly suitable for can doing in China hospital's penetration and promotion of fracture fixing operation.
