Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of non smoke ultrasound knife.
Background technology
Biological tissue is changed or be passed to ultrasonic energy by the application of ultrasound typically by end effect or surgical instruments etc.,
Some physiological effects are produced, tissue is carried out in particular with caused heat to burn hemostasis and cutting etc..In surgery surgical device
In tool ultrasound knife, generator produces high-frequency electrical energy, and transducer utilizes piezoelectric or electric magnetostrictive material by high-frequency electrical energy
Amount is converted into the vibration of machinery, and vibration amplification is delivered into end effector.
Ultrasound knife in the market its be disadvantageous in that：First, when cutter head carries out mechanical oscillation cutting with supersonic frequency
When tissue, can produce very high heat in cut place causes the liquid gasification of surrounding, and these steam can often cover endoscope
Camera lens, and then influence endoscope observation；2nd, when cutter head nearby exist many surgical operation materials for example coagulator, protein,
When blood, tissue particles and other component fluids, these surgical operation materials can be gradually solidified to the rise of temperature
Bit interface, and then have a strong impact on the service efficiency of cutter head, or even cause to shut down because of cutter head overload, and it is excessive outer
Section's operation material equally influences whether the field of view of endoscope.
And in the market also has some ultrasound knifes with suction device regarding to the issue above, but its equally there is also it is following not
Foot：First, suction device and the setting of ultrasound knife non-integral, frequently change suction device and operation apparatus and scouring camera lens is serious
Operation progress is influenceed, causes operating time to extend, does not only take up independent instrumentation passage and space and poor in timeliness, no
Beneficial to the security and efficiency for improving operation；2nd, suction device is continuation vacuum suction, and influence art is easily interfered on abdominal pressure
Middle exposure；3rd, smog is easy to disperse, and it is exactly that in time, smog and small amount bleeding are entered in the prior art that it, which is removed mostly important,
Row is effectively cleared up in time and is difficult to synchronize.
Also, laparoscopic surgery bleeding is mostly that local a small amount of bleeding is often not required to special suction device processing in the prior art,
Because suction device easily adsorbs surrounding tissue, caused haze effect is bad to local small amount bleeding and, and is cleared up using gauze
The visual field then takes the special time.
Therefore, it is badly in need of a kind of by suction device and ultrasound knife are structure-integrated, work synchronizes, structure is novel, it is more to be applicable
Sample, convenient and practical non smoke ultrasound knife.
