Description
Technical field
The present invention relates to a kind of surgical medical equipment, more particularly, it relates to a kind of composite ultraphonic with swinging structure
Vibrating handle and the ultrasonic orthopaedics delicate procedure system of tissue identification function.
Background technology
Modern medicine development is swift and violent, and ultrasonic surgical systems has been generally applicable in clinical surgery operation treatment, and it utilizes
Ultrasonic energy carries out surgical operation, and its prominent feature is to cut fine, safety, tissue selectivity and low temperature hemostasis etc..Super
The use of sound surgery systems, is greatly enriched operating means, improves operating quality, subtracts to a certain extent
The light pain of patient.Conventional Ultrasound bone-operating system, this system is mainly by main frame, ultrasonic handpiece, ultrasonic cutter and foot-operated
Switch composition.Wherein main frame mainly includes supersonic signal generator, power amplifier and embedded computer.Ultrasonic signal occurs
The small-power ultrasonic electric signal that device produces, can transducer work in driving handle after power amplifier amplifies；Embedded meter
Calculate owner to be responsible for coordinating and control complete machine work, receive control instruction, display instrument duty, it is achieved man-machine interaction and foot
Step on the functions such as control.Ultrasonic handpiece includes ultrasonic transducer and horn, completes ultrasonic electric signal is converted into ultrasonic mechanical wave,
After horn realizes Amplitude amplification, it is delivered to surgical knife tool.
In the Chinese invention patent document of Publication No. CN1039780C, open a kind of ultra-sonic surgical aspirator, this ultrasonic hands
Art instrument includes handle and main frame, is wherein provided with transducer, horn, flush pipe, cable, surgical knife tool etc. in handle.
In american documentation literature US5486162A, US5562609A, US5562610A, US6033375A, disclose respectively
The ultra-sonic surgical aspirator of longitudinal ultrasonic vibration can be produced.
But, in existing ultrasonic bone surgery instrument, the ultrasonic electric signal driving handle that supersonic signal generator produces
In ultrasonic transducer, ultrasonic electric signal is converted into ultrasonic mechanical wave by transducer, then after horn realizes Amplitude amplification, passes
It is delivered to surgical knife tool.Surgical knife tool can only porpoise in a longitudinal direction, efficiency of its cutting skeleton is low, and surgical knife tool
With the frictional force between wound surface is relatively big, easily causes the rising of cutting wound surface temperature, even can cause cutting wound
Neighbouring nerve and the hot injury of blood vessel.
In the Chinese invention patent document of Publication No. CN1732861, disclose the ultrasonic bone of a kind of complex vibration
Surgery apparatus, its handle configuration driven motor on ultrasonic transducer, make surgical knife tool not only can extensional vibration but also rotatable, thus carry
High cutting efficiency.
But, this patent is directly realized by swing by motor, and electric efficiency is low, and shaking moment is little.The present invention passes through motor
Driving swinging structure to realize swinging, motor plays peak efficiency all the time, and shaking moment is big, and ability to function is strong.
It addition, in existing ultrasonic bone surgery system, ultrasonic cutter is while cutting skeleton, it is likely that can cut simultaneously
Cut bones soft tissue, not only can affect procedure, more patient can be produced injury greatly.Existing ultrasonic bone surgery
In system, ultrasonic cutter is not the most avoided to hurt the function of bones soft tissue.
Summary of the invention
It is an object of the invention to provide a kind of composite ultraphonic vibrating handle with swinging structure, there is soft tissue simultaneously and know
The ultrasonic bone delicate procedure system of other function.It addition, provide the composite ultraphonic vibrating handle of a kind of swinging structure simultaneously, and
Bones soft tissue recognition methods.
The ultrasonic orthopaedics delicate procedure system of present invention design, by ultrasonic cutter, ultrasonic handpiece, main frame and foot switch group
Become.Ultrasonic handpiece is connected with main frame by cable, and foot switch connects with main frame also by cable.
Ultrasonic handpiece is the composite ultraphonic vibrating handle of a kind of swinging structure, and its structure includes: transducer, by supersonic frequency
The signal of telecommunication is converted into mechanical vibration；Swing mechanism, becomes rotary motion swinging, and drives transducer to swing together；Flexible close
Envelope parts, its inner ring is fixed on transducer, and outer ring is fixing with on shell, realizes sealing function when transducer swings；Motor,
Produce rotary motion, drive swing mechanism motion；Shell, for fixing of energy converter, swing mechanism and motor.
In above-mentioned ultrasonic handpiece, owing to the rear end in described shell is provided with driving motor, and this driving motor
Drive transducer to rotate by a swing mechanism, thus make the surgical knife tool being arranged on handle front end same vertically move
Time, also can carry out axial rotary oscillation, thus produce the compound motion with swing, the skeleton of operative site is cut
Cut, hole, grinding etc., make operator can control ultrasound knife as holding a pen smoothly and skeleton " is carved " go out any shape,
Improve cutting efficiency simultaneously, reduce the frictional force between cutter and wound face, thus reduce the cutting temperature of wound face,
And surgical knife tool can be avoided to concentrate due to stress and cause fracture.
Main frame includes: drive circuit, host center controller, supersonic signal generator, broadband excitation signals generator,
Soft tissue identification module.Host center controller sends control signal to supersonic signal generator so that it is start or stop to produce
Ultrasonic signal.The ultrasonic signal that supersonic signal generator produces exports to drive circuit, drives ultrasonic handpiece by drive circuit
With ultrasonic knife bar so that it is work.Broadband excitation signals generator produces wideband and encourages ultrasonic handpiece to pumping signal.Ultrasonic
Handle can produce response signal after being encouraged by broadband excitation signals, by analyzing described response signal, calculates resonance frequency
Rate is cheap, it is judged that whether ultrasonic cutter touches soft tissue, feeds back to host center controller.
Foot switch, is used for controlling ultrasonic output, facilitates operator in operation process, uses foot to control ultrasonic orthopaedics
Delicate procedure system, has liberated the both hands of operator, it is simple to operation technique.
In the very first time, soft tissue contact detection module can detect whether ultrasonic cutter contacts soft tissue, and to main frame
Master controller sends signal, and host center controller sends the output of stopping ultrasonic signal at once to supersonic signal generator
Instruction, prevents ultrasonic cutter from hurting soft tissue.Soft tissue recognition methods, produces broadband excitation by auxiliary signal driving source
Signal encourages ultrasonic handpiece.Ultrasonic handpiece is by producing response signal after broadband excitation signals, by analyzing described response
Signal, calculates the indexs such as resonance frequency shift, impedance, resonant frequency, amplitude, quality factor, phase contrast and power.According to resonance
The indexs such as frequency shift (FS), impedance, resonant frequency, amplitude, quality factor, phase contrast and power judge whether not in contact with skeleton group
Knit.As not in contact with skeletal tissue, soft tissue identification module sends instruction, host center controller to host center controller at once
The order stopping ultrasonic output is sent, it is to avoid ultrasonic cutter cuts to soft tissue, it is to avoid to patient's to supersonic signal generator
Injury.
