Abstract
The invention relates to a radio frequency ablation blood coagulator, which comprises an electrode needle which is electrically connected with the output end of a switch, wherein the input end of the switch is electrically connected with one end of a cable, and the other end of the cable is electrically connected with a power plug; the electrode needle is controlled by a control switch to generate radio frequency energy, and the generated radio frequency energy can allow liver tissue on a personate excision surface to dehydrate and coagulate quickly, so that local blood vessels and other piping systems are closed, blood flow entering liver is not blocked, and thick blood vessels to be disconnected are not required to be pretreated. Due to the adoption of the radio frequency ablation blood coagulator, the bleeding in the process of excision can be reduced obviously and even can be eliminated, the incidence of postoperative complication is reduced, and the process of liver excision is safe and quick.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of radio-frequency (RF) ablation blood coagulation device.
Background technology
The main method of treatment liver neoplasm remains hepatectomy at present.Because the vascularity of liver is complicated and blood supply is abundant, hepatectomy in the past invariably accompanies and bleeds profusely and higher case fatality rate.Along with going deep into that the dissection to liver is studied, the raising of surgical technic, the progress that peri-operation period is handled and anaesthetized, it is comparatively safe that hepatectomy has become.But excision to liver privileged sites tumor, especially be associated with the patient of liver cirrhosis, a spot of blood transfusion still the mortality massive hemorrhage may occur in the art, and blood transfusion may increase the incidence rate and the mortality rate of post-operative complication, even also can increase the probability of recurrence of PHC.Thereby, inquire into the focus that various liver blood flow control device are Genneral Surgery's area researches always in the hepatectomy so, guarantee that residual liver is subjected to ischemical reperfusion injury less for control and minimizing hepatectomy intraoperative hemorrhage minimizing blood transfusion as far as possible.So far various liver blood flow control devices still have many shortcomings, can not well reach the hemostatic effect.
Summary of the invention
In order to overcome the deficiency that above-mentioned prior art exists, the object of the present invention is to provide a kind of radio-frequency (RF) ablation blood coagulation device, the radio-frequency (RF) energy that this device produces can make the rapid dehydration of the excision face of plan hepatic tissue solidify, closed local vascular and other tubings, do not block into liver blood stream, need not to anticipate will be from disconnected thick blood vessel.Can obviously reduce hemorrhage even not hemorrhage in the excision process, reduce the incidence rate of post-operative complication, make the hepatectomy process safer, quick.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of radio-frequency (RF) ablation blood coagulation device comprises the electrode needle 2 that the outfan 3 with switch 1 is electrically connected, and the input 4 of switch 1 and an end of cable 5 are electrically connected, and the other end of cable 5 and attaching plug 6 are electrically connected.
The quantity of described electrode needle 2 is 4-6.
Come control electrode pin 2 to produce radio-frequency (RF) energy by master cock 1, the radio-frequency (RF) energy that produces can make the rapid dehydration of the excision face of plan hepatic tissue solidify, closed local vascular and other tubings, do not block into liver blood and flow, need not to anticipate will be from disconnected thick blood vessel, can obviously reduce hemorrhage even not hemorrhage in the excision process, reduce the incidence rate of post-operative complication, make the hepatectomy process safer, quick.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
The present invention will be described in more detail below in conjunction with accompanying drawing.
As shown in drawings, radio-frequency (RF) ablation blood coagulation device comprises the electrode needle 2 that the outfan 3 with switch 1 is electrically connected, and the input 4 of switch 1 and an end of cable 5 are electrically connected, and the other end of cable 5 and attaching plug 6 are electrically connected.The quantity of described electrode needle 2 is 4.
Operation principle of the present invention is: under B ultrasonic guiding when local anaesthesia or row abdominal, according to lesions position and scope to the zone of consider excision carry out corresponding liver free after, also can carry out conventional ultrasonic examination in the art, to determine the relation of focus and important blood vessels and bile duct, under ultrasonic guidance, the vascular that should keep made a mark and mark the mark line of intending excision extension in liver surface, along intending the excision extension mark line, begin electrode needle 2 is penetrated hepatic tissue from the initial position of planning to excise, simultaneously attaching plug 6 is inserted power supply, Closing Switch 1, electrode needle 2 is penetrated organizes the deep to begin to melt to solidify, solidify back cut-off switch 1, electrode needle 2 substeps are extracted, whenever extract a step Closing Switch 1 once, the startup of doing next step subsequently again with extract, forming this time inserting needle position thus organizes whole melting from deep to shallow to solidify, repeat aforementioned operation successively until the coagulation necrosis band that forms wide about 1.2～1.5cm along the excision extension mark line, directly cut to the deep solidification zone of each inserting needle with scalpel with 1/3 place of nearly cut-away area in this necrosis, can advance electrode needle 2 once more at this position as hemorrhage sign in the incision process to do additional radio frequency, guarantee that scalpel cuts the not hemorrhage of process, behind the excision focus zone the visible tubular structure stump that has been solidified of residue liver section sewed up and close, residue liver section must leave the solidifying front that melts of 0.8～1.0cm thickness.Confirm to close abdomen after the no hemorrhage and bile leakage.
