Description
Technical field
It is free for tissue and blood vessel, nerve, organ the present invention relates to a kind of electric knife of safe and efficient tissue separation,
Belong to surgical operating instrument technical field.
Background technology
Electric knife (high frequency electro surgical unit) is a kind of electrosurgical unit for replacing mechanical operation knife to carry out tissue cutting.It leads to
The high-frequency high-voltage current for crossing the generation of active electrode tip is heated when being contacted with human body to tissue, and realization divides injected organism tissue
From and solidification so that play cutting and hemostasis purpose.
Separation principle is as follows：There is certain loose gap between tissue and blood vessel, nerve, high-frequency and high-voltage gas is quickly noted
Gap can be increased by entering, and separate tissue and blood vessel, coordinate electric knife cutting, can make tissue and blood vessel, nerve separation.
The free tissue of modern surgery operation, blood vessel, the technology of nerve include that passivity is free, sharp property is dissociated (scalpel, tissue
Cut, electric knife, ultrasound knife etc.), due to being combined closely between normal structure and blood vessel, nerve, gap is not obvious, if to swim
During from target organ, blood vessel or nerve, operation difficulty is big, easily damages target organ, nerve or angiorrhoxis etc., brings operation
In mistake damage, reduce the security of operation.
The content of the invention
The technical problem to be solved in the present invention is how to realize tissue and blood vessel, the safe separating of nerve, and reduction is damaged by mistake
Probability, improves the security of operation.
In order to solve the above-mentioned technical problem, the technical scheme is that providing a kind of tissue separation electric knife, including knife
Body, blade front end forms knife neck, knife throat end connection cutter head, it is characterised in that：Vent line, the knife are provided with the blade
The front end of head is provided with the gases at high pressure outlet with vent line insertion.
Preferably, the blade end is provided with handle of a knife, and the entrance of the vent line is located at handle of a knife rear end, the breather pipe
The outlet on road is the gases at high pressure outlet.
Preferably, the knife neck is taper.
Preferably, the cutter head connection controlling machine box.
Preferably, the handle of a knife is provided with the electric knife switch for being used to control cutter head whether to work.
Preferably, the handle of a knife, which is provided with, is used to control gases at high pressure to export whether the air knife of outlet is switched.
Preferably, the blade is isolation material.
Preferably, the cutter head is metal material.
Preferably, the cutter head is electric knife.
Present invention also offers the method for work that above-mentioned tissue separates electric knife, it is characterised in that：In surgical procedure, grip
Handle of a knife, pins air knife switch first, and gases at high pressure are entered by vent line, is then exported and sprayed by gases at high pressure, gases at high pressure
Tissue space is filled, tissue to be separated is separated with organ, blood vessel, nerve；Then electric knife switch is pinned, starts cutter head, uses knife
Head is to needing the nerve, the blood vessel that cut off to cut, so as to reach exposed organ, blood vessel, nerve, it is to avoid blood vessel, the mistake of nerve
Damage may.
The device that the present invention is provided overcomes the deficiencies in the prior art, by between high-frequency and high-voltage air-flow Fast Filling tissue
Gap, the gap increase between the normal structure made and blood vessel, organ, operation technique gap increase coordinates electric knife cutting, can
Operating time is reduced, procedure efficiency is improved, reduction misses damage probability, improves operation safety.
Brief description of the drawings
Fig. 1 separates electric knife structural representation for the tissue that the present embodiment is provided.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
Fig. 1 separates electric knife structural representation for the tissue that the present embodiment is provided, and described tissue, which separates electric knife, to be included
Blade 4, the front end of blade 4 forms in the knife neck 3 of taper, the front end of knife neck 3 connection cutter head 1, blade 4 and has opened vent line 8, blade
4 ends are provided with handle of a knife 9, and the front end of cutter head 1 is provided with gases at high pressure outlet 2, and the entrance of vent line 8 is located at the rear end of handle of a knife 9, ventilation
The outlet of pipeline 8 is gases at high pressure outlet 2.
Vent line 8 is connected equipped with air knife switch 5 on source of the gas, handle of a knife 9, and air knife switch 5 is used to control gases at high pressure to export 2
Whether outlet.
Cutter head 1 connects controlling machine box, equipped with electric knife switch 6 on handle of a knife 9, electric knife switch 6 be used to controlling cutter head 1 whether work
Make.
The bore of gases at high pressure outlet 2 is 1mm.
