Description
Technical field
The utility model relates to area of medical devices, rotatable microwave needle under especially a kind of laparoscope.
Background technique
Microwave ablation is the thermal ablation techniques for developing faster one more than 10 years for oncotherapy.Microwave is to biological tissue
Heating mechanism there are two aspect: first is that the principal element of dipole heating and microwave heating.It is micro- in frequency > 900MHz
Under wave electromagnetic field effect, the dipoles charge polarity such as hydrone in tumour is unbalance, rapidly changes with the alternation of microwave electric field
Direction, with the frequency overturning per second more than million times and mutual frictional impact, generating a large amount of heat keeps tissue degeneratiaon downright bad；Separately
It on the one hand is Ion Heating, the ion in tissue also changes direction rapidly under the action of microwave electromagnetic field and generates vibration simultaneously
Mutually collision, makes kinetic energy be changed into thermal energy.It can be seen that the heating process of microwave is that group is woven in active heat production under the action of electromagnetic field,
High temperature is rapidly reached in short time.Compared with radio frequency and laser ablation, microwave ablation has heating rate fast, coagulation vessel ability
By force, influenced by blood flow factor it is small, can multiple antennas act on simultaneously, normal freezing range is larger and the features such as stabilization, becomes percutaneous heat
Great potential and a treatment means for having applications well prospect in ablation and surgical ablation treatment.Also can replace completely

All kinds of surgical instrument types increased.The method of detachment include basis finger or clamp method to use such as ultrasound knife, radio frequency
The instruments based on complex technology such as energy knife, Water Cutting knife, tissue closure instrument, surgery closer.These methods and strategies purposes are equal
It is to reduce by intraoperative hemorrhage and blood transfusion bring postoperative complications.In addition, also to consider emphatically when selecting various methods
Such as operating time, practicability and ease for use, to the lesion size of liver, expense in terms of these.Traditional liver parenchyma detachment method is
From finger milling process to pincers milling process, isolates pipeline and ligatured cutting.Compared with referring to milling process, pincers milling process is more quick, experienced
Patient can accurately judge whether there is the presence of pipeline in clamp tissue by feel.Clamp milling process detachment liver parenchyma
When, tiny vena hepatica can grind with pincers and be ground disconnected, lead to the bleeding of section, tied with 8 word of thin silk thread.No matter stone roller is referred to
Method still clamps milling process, requires the cooperation in in-degree sequence (Pringle method).With high-tech progress and with medicine skill
Art fusion derives the new technology of many liver parenchyma detachments, but in traditional liver parenchyma detachment operation, is inhaled using traditional ultrasound
Draw the methods of knife (Cavitron ultra-sonic surgical aspirator, CUSA), water knife and Vascular closure device and pincers
The defects of milling process is the same, and operating time is longer, and amount of bleeding is big, and the complication of postoperative leak is higher.
