Description
Technical field
The utility model belongs to the field of medical instrument technology more particularly to a kind of Novel neurosurgery bipolar electrocoagulator.
Background technique
Currently, the prior art commonly used in the trade is such that bipolar coagulation came out in 1940, the area of it and monopolar coagulation
It is not to eliminate the dispersing electrode contacted with patient posterior, and two electrodes is connect respectively on two blades of a tweezers,
It is insulation between two blades of this tweezers.Using when electric current only pass through the tissue between two tip of tweezers, therefore institute's electricity demand is big
To reduce, 1/4 to the 1/3 of monopolar coagulation is generally only needed, electricity can even be reduced to when stopping blooding in significant points such as spinal cord
Not as good as the 1/10 of monopolar coagulation, thus the diffusion of heat and neighbouring damage are accordingly reduced.
In addition, bipolar coagulation can similarly electrify in the presence of having liquid such as physiological saline, cerebrospinal fluid or blood
Solidifying anastalsis, this is also less than monopolar coagulation.Monopolar coagulation can be with a variety of surgical instruments such as haemostatic clamp, tweezers, attraction
Device, scalpel or steel wire snare etc. contact and play the multiple uses such as hemostasis or cutting；But its electricity demand is big, thermal diffusion range
Greatly, larger to surrounding tissue damage, change in organization is still being seen apart from 1 centimeters of cutting, thus monopolar coagulation is in important portion
Position such as function of cortex area, important blood vessels are nearby and brain stem, spinal cord, nerve root etc. should not be applied.
After decades of development, bipolar electrocoagulator technology is constantly mature, but there are still certain defect, such as Chinese document is special
Sharp CN201930068U, for the patent by electrode pipe sleeve outside electrode needle, the tip portion of electrode needle is exposed outside electrode tube, uses
When, electrode needle can be contacted with hemostasis tissue simultaneously with electrode tube, but the range stopped blooding is too small, can only be in the end face diameter of electrode tube
It is interior.To solve the problems, such as that hemostasis range is too small, Chinese patent literature CN203790036 has invented a kind of abdomen with suction function
Endoscope-assistant surgery bipolar coagulation carries out clamping electric discharge realization to the tissue being located between two bipolar coagulation heads and stops blooding to tissue,
But activity space needed for bipolar coagulation head the space occupied and clamping is all larger, it is possible to cause newly to puncture channel when in use
Injury.
In conclusion problem of the existing technology is:
(1) range of existing bipolar electrocoagulator hemostasis is too small, can only realize that blood coagulation stops in the end face diameter of electrode tube
Blood；
(2) the space occupied and the required activity space of clamping are all larger, it is possible to cause newly to puncture channel when in use
Injury.
