Description
Technical field
The invention belongs to medical apparatus and instruments, is mainly used in fracture synthetism computer control adjustment, location and fixing.
Background technology
After conventional fractures adopts the X-ray film making more, adjust, reset, locate synthetism with hands with Jie's experience and technology by the orthopedist, fix with Gypsum Fibrosum, clamping plate or holder then, because of the plaster fixation mode very backward, existing less employing, holder uses comparatively general.But because fracture fixing apparatus made by metal, weight is big, uses inconvenience, and this device only can be used in fixing use the after the manual synthetism, adjusts in the time of can not doing synthetism and uses.In recent years, a kind of synthetism adjustment, fix the interoperable bone fracture devices development of two kinds of merits and finish, yet because it has the adjustment capability of two degree of freedom, can not realize comprehensive adjustment, because of adopting metal material to manufacture, ray occurs and block again, do not reach clinical application effect.At present, the applicant succeeds in developing the bone fracture device of all being manufactured by nonmetallic materials, can realize comprehensive adjustment in the synthetism process, and the device use that fixes, and has obtained china national practical new-type patent power.Also need be carried out by hand by the doctor but it resets to adjust to operate, its convenience is relatively poor, and efficient is lower.
Summary of the invention
The purpose of the invention is exactly the problem that exists in manually-operated at the bone fracture device that the nonmetallic materials that I succeed in developing are manufactured, design provides a kind of computer control reduction external fixator, by adopting host computer control speed change driver, speed change driver is handled and respectively to be driven flexible axle and finish and each parts of bone fracture device are carried out synthetism reset and adjust action, reach adjust resetting and setting fracture and fixing accurately and reliably, efficient height, the measured purpose of matter.
The basic design of the invention is, this device comprises bone fracture device, speed change driver and host computer, the upper and lower spicule that is provided with on the speed change driver with bone fracture device is respectively adjusted the corresponding cooperation of interface drive interface, Compression and Expansion drive interface, move on comprehensive move down drive interface, the left-handed dextrorotation of rotating ring drives interface, the parallel driving interface that moves to right that moves to left, and utilize corresponding driving soft, axle with bone fracture device respectively adjust interface and speed change driver respectively drive the corresponding connection of interface; On the panel of speed change driver, be provided with the wire for PC input window, in window configuration upper and lower spicule, Compression and Expansion, move on comprehensive move down, the left-handed dextrorotation of rotating ring, the parallel control socket such as move to right that moves to left; Be provided with on the host computer display screen fracture site image display screen and Compression and Expansion, left-handed dextrorotation, on move move down, move to left move to right, on and sign such as spicule down, with signs such as shift length, time, execution, still image, termination, so far constitute computer control reduction external fixator.
The invention have the synthetism adjustment reset automaticity height, action precisely, high, effective, the medical worker of therapeutic efficiency avoids the characteristics that the x-ray width of cloth is penetrated, and can realize operated from a distance.
