Description
Technical field
The invention belongs to orthopaedic medical treatment equipment technical field is and in particular to a kind of nail taking out apparatus in orthopaedics.
Background technology
21 century is filled with the century of opportunities and challenges, and the China of 21 century brims with life and vigor everywhere.China
Economy flourish, already become the big country having certain power of influence, living standards of the people also correspondingly have very significantly
Improve.The rhythm of life of people is accelerated, and along with the fast development of private car, vehicle accident is in a kind of ascendant trend, because handing over
Interpreter is so the number of the patient that causes injury is doubled and redoubled.
Chinese orthopedic medical device development time is not long, and the time only has 20 years about, the orthopaedic medical treatment machinery city of the nineties
Substantially belong to buyer's market, orthopedist is much looking for producer, asks producer to do products that some are suitable for, start the nineties by
Gradually there is transnational M＆G, a collection of native country national enterprise of being simultaneously also born.Orthopaedics is mainly dissection, the life studying skeletal musculature
Reason and pathology, its therapeutic modality mainly has medicine, naturopathy and operative treatment, more lays particular stress in three of the above Therapeutic Method
In operative treatment, accounting is maximum.Medical apparatus and instruments can be divided into interior fixation and the two ways of outer fixation, implant according to physical structure
Interior is referred to as interior fixing main inclusion joint, blade plate, screw etc., and outer fixation is a kind of fixed form in vitro, main
External fixer to be included, clamping plate, binder, Gypsum Fibrosum etc., two ways compare main within fixing based on, two ways is provided to
Fixing fracture site promotes callus formation to fully recover as early as possible, and bone injury is constantly in high ratio, and orthopaedics takes nail as bone injury
Last link after healing, becomes particularly important, and instantly, the orthopaedics of majority hospital of China takes nail, how using taking nail manually,
Not only stability is bad, and easy postoperative infection, it has not been convenient to the technical problem such as teaching demonstration experiment, therefore, invents a kind of bone
Section's device for fetching nail, is of practical significance very much.
Computer tomography is a kind of important imaging means obtaining internal structure of body information by lossless manner, it
Have high-resolution, high sensitivity and the inferior many merits of multilamellar, be the maximum medical imaging diagnostic device of China's installation amount
One of, it is widely used in each medicinal and check field.However, needing to use x-ray due in ct scanning process, therefore
In ct scanning, the radiation dose problem of x-ray is increasingly subject to people's attention.Reasonable employment low dosage (as low as
Reasonably achievable, alara) principles and requirements, on the premise of meeting clinical diagnosises, reduce the spoke to patient as far as possible
Penetrate dosage.
The realization of traditional ct is based on x-ray source such as x ray machine and high energy acclerators, examined object body to be irradiated, and right
The detector gathered data answered, makes x-ray not by rotation translation of the swivel mount of ct system etc. etc. in scanning process
With passing through examined object body under angle, thus obtaining the light intensity data of examined object body diverse location, (namely scan data can be described as again
Data for projection), the faultage image of examined object body can be reconstructed using obtained scan data.Traditional ct system needs accurately
Ground controls the relative position of examined object body and accelerator and detector in scanning process, to meet to needed for tomographic image reconstructing
Data qualification.At present, traditional scanning and imaging method, takes longer, therefore human body is still suffered from a certain degree of radiation
Harm.
