Description
Technical field
The invention belongs to technical field of medical equipment, more particularly, to the cold cold probe of ablating device electricity consumption of electricity.
Background technique
Cryosurgery treatment is to damage in method and human history with ablation lesion tissue to make earliest using ultralow temperature
Pathological tissues ablation techniques.From nineteen sixty American Psychiatry surgeon Irving Cooper and engineer Arnold Lee
Probe shape liquid nitrogen freezing apparatus is invented and for using liquid nitrogen as cryogenic fluid (refrigerant), heated nitrogen after freezing brain tissue
Liquid nitrogen frozen surgical device as high temperature refrigerant (heating agent) is applied to treat various tumours.From generation nineteen ninety, based on coke
The invention and application of ear-thomson principle gas throttling type cryogenic freezing surgery system, such as using high pressure argon gas freezing and helium
The argon helium knife of gas rewarming is widely used to the cryoablation treatment of various innocent and malignant tumours.
Due to will appear biggish variable density before and after tissue or organ, therefore the outstanding advantages of cold therapy are to pass through
The medical imaging procedures such as ultrasound relevant to density, CT and MRI, the image of display tissue freezing range.The group that scientific circles prove
Knitting the lethal temperature range of cryoablation is and to freeze the lowest temperature (usually less than -80 DEG C) of regional center certainly extremely lower than -40 DEG C
The lethal temperature range, much smaller than freezing region itself (typically less than half).That is -40 DEG C of freezing region extremely freezing side
A large amount of tissues in edge (0 DEG C) range are not melted effectively, still can be survived.The namely freezing that shows of medical image
Region and non-treatment boundary, especially in neighbouring big angiosomes.
A large amount of scientific researches also turn out simultaneously: reaching effective cryoablation to tumor tissues, it is necessary to using " cold twice
The circulation of jelly-rewarming ".And recycle every time, 20~30min is needed, the process of cryoablation takes a long time.Cryoablation technology is anxious
Need a kind of thoroughly ablation and time-consuming shorter improved method.
Electricity ablation is the ablation techniques based on DC electric field, AC field or impulse electric field, including electrolysis ablation, electroporation
Ablation etc..Electrolysis ablation is also referred to as electrochemotherapy (EChT) early in just having been used for micro-wound tissue ablation 19th century,
It is to melt probe by electricity of the root cutting in processing tissue DC current is transmitted in therapeutic domain, causes therapeutic domain local
PH value variation and form cytotoxin environment, and some new chemical substances for being formed in electrolytic process and then cause thin
The method of born of the same parents' death.Electrolysis ablation needs very low DC current (tens arrive several hundred milliamperes) and very low voltage (several to ten
Several volts).Therefore equipment is not only simple but also safe, this is its advantage place.But due to the length of time of this cell death method
It is the diffusion rate of electrochemical products as being generated in tissue and the concentration of electrolysate required for Apoptosis is caused to be determined
Fixed, therefore, the therapeutic process for being electrolysed ablation takes a long time, and from dozens of minutes to a few houres etc., this is also electrolysis ablation skill
The limitation of art.
Electroporation ablation is to make cell membrane permeabilization by applying very of short duration high-amplitude electric field pulse, causes cell by group
It knits liquid and poisons lethal, cell membrane the degree of transparency is the exercising result of electric field strength.Electroporation is divided into reversible electroporation and irreversible
Electroporation: reversible electroporation is available to make lipid bilayer generate reversible hole, to allow point of such as gene and drug
Son is introduced into cell.Irreversible electroporation principle is to act on to break up higher than 500~600V/cm electric pulse using electric field strength
Tumor cell membrane generates cell membrane a large amount of permanent nanometer level microporous, to destroy intracellular steady state, promotes Apoptosis,
Eventually lead to the thorough death of cell.It has the advantages that not heat production, does not generate damage to cavity, blood vessel and nerve etc.；Disadvantage
It is that ablation range is not visible and the incomplete problem of ablation.
Therefore, it is necessary to the ablations of a kind of new therapeutic device the advantages of merging above-mentioned tumour ablation and above-mentioned apparatus adaptation
Probe solves the problems, such as therapeutic device in the prior art or treatment method.
