Description
Technical field
The present invention relates to use in a kind of ultrasonic orthopaedics delicate procedure system with swing function ultrasonic handpiece and a kind of ultrasonic orthopaedics delicate procedure composite ultraphonic vibrating handle with swinging structure.
Modern medicine development is swift and violent, and the supersonic operation system is applied in the clinical surgery operation treatment at large, and it utilizes ultrasonic energy to carry out surgical operation, and its outstanding characteristics are that cutting is meticulous, safety, tissue selectivity and low temperature hemostasis etc.Operating means have greatly been enriched in the use of ultrasonic cut anthemorrhagic operation system, have promoted operating quality, have alleviated patient's pain to a certain extent.Routine ultrasonic bone surgery system, this system mainly is made up of main frame, ultrasonic handpiece, ultrasonic cutter and foot switch.Wherein main frame mainly comprises supersonic signal generator, power amplifier and embedded computer.The ultrasonic signal of telecommunication of small-power that supersonic signal generator produces is after power amplifier amplifies, but the transducer work in the driving handle; Embedded computer mainly is responsible for coordinating and the work of control complete machine, receives control instruction, and the display instrument duty realizes functions such as man-machine interaction and foot-operated control.Ultrasonic handpiece comprises ultrasonic transducer and horn, finishes the ultrasonic signal of telecommunication is converted into ultrasonic mechanical wave, after horn realizes that amplitude amplifies, is delivered to surgical knife tool.
Be in the Chinese invention patent document of CN1039780C at publication number, disclose a kind of ultra-sonic surgical aspirator, this ultra-sonic surgical aspirator comprises handle and main frame, wherein is provided with transducer, horn, syringe pipe, cable, surgical knife tool etc. in the handle.
In american documentation literature US5486162A, US5562609A, US5562610A, US6033375A, the ultra-sonic surgical aspirator that can produce the longitudinal ultrasonic vibration is disclosed respectively.
But, in existing ultrasonic bone surgery instrument, the ultrasonic transducer in the ultrasonic signal of telecommunication driving handle that supersonic signal generator produces, transducer is converted into ultrasonic mechanical wave with the ultrasonic signal of telecommunication, after horn realizes that amplitude amplifies, is delivered to surgical knife tool again.Surgical knife tool is porpoise in a longitudinal direction, the efficient of its cutting bone is low, and the frictional force between surgical knife tool and the wound surface is bigger, causes the rising of cutting wound surface temperature easily, even can cause near the nerve of cutting wound and the hot injury of blood vessel.
Be in the Chinese invention patent document of CN1732861 at publication number, disclose a kind of ultrasonic bone surgery instrument of complex vibration, its handle is the configuration driven motor on ultrasonic transducer, but makes not only extensional vibration but also rotatable of surgical knife tool, thereby improves cutting efficiency.
But this patent directly realizes swing by motor, and electric efficiency is low, and shaking moment is little.The present invention realizes swing by the driven by motor swinging structure, and motor is brought into play peak efficiency all the time, and shaking moment is big, and ability to function is strong.
In addition, in the existing ultrasonic bone surgery system, ultrasonic cutter cuts to bones soft tissue possibly simultaneously in cutting bone, not only can influence the operation process, more can produce great injury to the patient.In the existing ultrasonic bone surgery system, also do not avoid ultrasonic cutter to hurt the function of bones soft tissue.
Summary of the invention
The purpose of this invention is to provide and use the composite ultraphonic vibrating handle with swinging structure in a kind of ultrasonic orthopaedics delicate procedure system with swing function ultrasonic handpiece and a kind of ultrasonic orthopaedics delicate procedure.
The ultrasonic orthopaedics delicate procedure system with swing function ultrasonic handpiece of the present invention design is made up of ultrasonic cutter, ultrasonic handpiece, main frame and foot switch.Ultrasonic handpiece is joined by cable and main frame, and foot switch also joins by cable and main frame.
Ultrasonic handpiece is a kind of composite ultraphonic vibrating handle of swinging structure, and its structure comprises: transducer becomes mechanical vibration with the supersonic frequency electrical signal conversion; Swing mechanism, will rotatablely move becomes swing, and the drive transducer is swung together; Flexible seal member, its inner ring is fixed on the transducer, the outer ring fixing with shell on, realization sealing function when transducer swing; Motor, generation rotatablely moves, and drives the swing mechanism motion; Shell is used for fixing of energy converter, swing mechanism and motor.Have the composite ultraphonic vibrating handle of swinging structure, it is hollow structure, has complete fluid path.In above-mentioned ultrasonic handpiece, because the rear end in described shell is provided with drive motors, and this drive motors drives the transducer rotation by a swing mechanism, so just make the surgical knife tool that is installed in the handle front end when vertically moving, also can carry out axial rotary oscillation, thereby produce the compound motion with swing, skeleton to operative site cuts, boring, grinding etc., make operator control ultrasound knife stably as holding a pen skeleton " engraving " is gone out Any shape, improved cutting efficiency simultaneously, reduced the frictional force between cutter and the wound face, thereby reduced the cutting temperature of wound face, and can avoid surgical knife tool owing to stress concentration causes fracture.Main frame comprises: drive circuit, host center controller, supersonic signal generator, broadband excitation signal generator, soft tissue identification module.The host center controller sends control signal and gives supersonic signal generator, it is begun or stops to produce ultrasonic signal.The ultrasonic signal that supersonic signal generator produces is exported to drive circuit, drives ultrasonic handpiece and ultrasonic knife bar by drive circuit, makes its work.This auxiliary signal driving source that main frame has, it can produce the broadband pumping signal and encourage ultrasonic handpiece.Ultrasonic handpiece is subjected to can producing response signal after the broadband excitation signal energizes, and by analyzing described response signal, it is cheap to calculate resonant frequency, judges that whether ultrasonic cutter touches soft tissue, feeds back to the host center controller.
Foot switch is used for the ultrasonic output of control, and the handled easily person uses foot to control ultrasonic orthopaedics delicate procedure system in operation process, and the both hands of having liberated the operator are convenient to operation technique.
Soft tissue contact detection module can detect ultrasonic cutter in the very first time and whether contact soft tissue, and send signal to the host center controller, the host center controller sends the instruction of the output that stops ultrasonic signal at once to supersonic signal generator, prevent that ultrasonic cutter from hurting soft tissue.The soft tissue recognition methods produces the broadband pumping signal by the auxiliary signal driving source and encourages ultrasonic handpiece.Ultrasonic handpiece is subjected to producing response signal after the broadband pumping signal, by analyzing described response signal, calculates indexs such as resonance frequency shift, impedance, resonant frequency, amplitude, quality factor, phase contrast and power.Judge whether not contact skeletal tissue according to indexs such as resonance frequency shift, impedance, resonant frequency, amplitude, quality factor, phase contrast and power.As do not contact skeletal tissue, and the soft tissue identification module sends instruction to the host center controller at once, and the host center controller sends the order that stops ultrasonic output to supersonic signal generator, avoids ultrasonic cutter to cut to soft tissue, avoids the injury to the patient.
