Abstract
The invention discloses a minimally-invasive ultrasonic knife the main body of which is made of rolled steel containing nickel and can not be damaged because of the high-frequency vibration, the range of diameter is within 2-5mm, an ultrasonic emulsification effect can be generated in the ultrasonic high-frequency vibration, the object to be sucked can be broken into pieces and emulsified because the negative pressure is improved by the suction pipe connected with the back end, therefore, operation course speed is increased.
Description
Technical field
The present invention relates to a kind of minimally invasive ultrasound knife.
Background technology
Endoscope is a kind of optical instrument, till now the history in 200 years has been arranged from its appearance.Along with developing rapidly of advanced science and technology, the kind of endoscope and level have also had the progress of advancing by leaps and bounds, and develop into fujinon electronic video endoscope and ultrasonic electronic mirror from hard tube mirror and fibrescope.And be applied to endoscopic surgery operation, and instruments such as TURP ring, glass cutting knife, biopsy forceps are arranged, also not occurring with the ultrasonic emulsification is the minimally invasive ultrasound knife of principle.
Summary of the invention
The present invention relates to a kind of minimally invasive ultrasound knife, its main body is made of steel containing nickel, can not damage because of high-frequency vibration, diameter range under ultrasonic dither, just can produce the effect of ultrasonic emulsification in the 2-5 millimeter, because the rear end connects suction catheter, increased negative pressure, made the object that is sucked, accelerated the operation process by shatter, emulsifying.
The specific embodiment
Below the specific embodiment of the present invention is further described:
Main body of the present invention adopts steel containing nickel to make, and diameter range under ultrasonic dither, just can produce the effect of ultrasonic emulsification in the 2-5 millimeter, because the rear end connects suction catheter, has increased negative pressure, makes the object that is sucked by shatter, emulsifying.
Claims (3)
1, a kind of minimally invasive ultrasound knife, it is characterized in that by hollow ultrasonic emulsification syringe needle and after connect conduit and form.
2, minimally invasive ultrasound knife as claimed in claim 1 is characterized in that its main body adopts steel containing nickel to make.
3, minimally invasive ultrasound knife as claimed in claim 1 is characterized in that its diameter is in 2-5 millimeter scope.
