Abstract
The utility model relates to a double electrode water dripping electrical knife for liver cutting, which is used for a surgical liver cutting operation. The utility model is composed of a knife head, a knife body handle, a water dripping device and an electrode plug, and is matched with a socket for a pair of double electrode coagulation forceps to use, wherein the knife head is positioned on the top end of the knife body handle, the electrode plug is arranged on the tail end of the knife body handle, and the water dripping device is arranged on the upper side of the tail part of the knife body handle. The utility model has novel structure and simple operation and is matched with a single electrode electrical knife to operate, and thus, the complicated liver cutting operation can be easily and timesaving. The operation of trimming cut and hemostasia is carried out under direct vision, and the utility model does not generate side injury to normal liver tissues. The utility model is provided with the water dripping device; during electrocoagulation, temperature is lowered, tissue carbonization is reduced, the tissues are not easy to adhere to the knife head to form eschar, and hemostasia performance is persistent and stable. The utility model can be used widely popularized and applied to large, medium and small hospitals.
Description
Technical field
The utility model discloses a kind of surgery cuts the bipolar liver of dripping that liver surgery uses and cuts electric knife.
Background technology
Along with dissection, physiology, the pathological knowledge of medical science, by treating as diseases such as hepatolith in hepatocarcinoma, the liver to liver leaf, the even irregular excision of section to the human liver.Tradition is cut liver and is used " cutter " hardly, generally is to separate with handle of a knife or mosquito forceps passivity along the pre-tangent line of liver, keeps and does not rupture than trunk or bile duct, further cuts off to finish with the mosquito forceps clamp and cuts liver.So little blood vessel and hepatic sinusoid are still hemorrhage more, go into the liver blood flow resistance for the hemorrhage employing of minimizing sometimes and break, and cause liver function injury, so the blocking-up time are subjected to certain limitation.Along with the development of cutting liver surgery, cut in the recent period liver extensively adopt cut liver instrument such as electric knife, laser scalpel, argon blood coagulation device (ABC), super cutter (CUSA), the microwave coagulation treatments (MTC) etc. inhaled are operated.Common electric knife and laser scalpel are because to also having dissection than trunk and bile duct, haemostatic effect is imprecise, only can be used for cutting the liver tunicle.Argon blood coagulation device (ABC) costs an arm and a leg, and requirement can not same electrocardio in the use, monitor such as breathing share.The super cutter (CUSA) of inhaling can make the fragmentation of contact hepatic tissue by machine vibration, does not also have obvious hemostatic function.Recently, microwave coagulation treatment (MTC) is cut liver and is used more extensively, thrusts needle electrode during operation earlier and is cured, and by putting into line, cuts liver with scalpel then in the middle of solidifying band, cuts edge and separate tangent plane with the handle of a knife passivity in the limit.The microwave coagulation treatment haemostatic effect is definite, has improved the safety of operation.But this machine exists and leaks the non-treated tissue of easily burning, and easy damaged causes massive hemorrhage than trunk during acupuncture, peels off easy fracture when solidifying bile duct and trunk, causes difficulty for further ligation, and microwave can not make bile duct solidify and fastens problem such as plug.
Summary of the invention
The purpose of this utility model is exactly to cut the problem that liver surgery exists at above-mentioned surgery, adopt a kind of simple in structure, have the heat sink that drips, can finish the apparatus of cutting liver surgery smoothly with the Single-pole electric knife compounding practice, its operation is very easy, effect is very obvious, thereby provides a kind of novel bipolar liver of dripping to cut electric knife.
The technical solution of the utility model is as follows:
The bipolar liver of dripping cuts electric knife to be made up of cutter head, blade handle, dripping device and electrode plug, with the supporting use of bipolar coagulation forceps socket.Cutter head is positioned at blade handle top, and electrode plug places blade handle tail end, and blade handle tail upside is established dripping device.
Cutter head contains three pieces of blades, three pieces of blade indentations are arranged and are fixedly mounted on blade handle top, the left and right side cutter head is drawn receiving electrode plug one utmost point by same lead line hole in the blade handle, and middle cutter head is drawn another utmost point of receiving electrode plug by another lead another line hole in the blade handle.
The blade handle is a plate body, and the groove that drips is established in inside, and the groove top of dripping is communicated with the inboard microdroplet of cutter head water hole, and tail end connects the joint that drips.
Blade handle tail upside indentation, there is provided with dripping device, and dripping device contains weep pipe and star wheel, the weep pipe one termination blade handle joint that drips, and the star wheel turning cylinder is positioned at blade handle tail upside breach groove, but rotation moving switch spinning roller switch weep pipe.
The bipolar electrode plug places blade handle tail end, is connected with the bipolar coagulation forceps socket is supporting.
Operational approach and points for attention: the open star wheel that drips during operation, speed of dropping water should be controlled appropriateness; Can be earlier during operation with the bipolar liver cutting knife that the drips liver tunicle of fulgerizing, the reuse Single-pole electric knife cuts, and cuts liver with the bipolar electric knife passivity of dripping then; The bipolar liver of dripping that slides when cutting liver cut electric knife speed be difficult for too fast, the limit hemostasis of cutting edge, the cutter head that can swing fully stops blooding; To the above liver interior conduit of 3mm that keeps, can under direct-view, adopt the maneuver ligation; Action should be soft during operation, and strength should be appropriate; If broken hepatic tissue filling is arranged between cutter head, can improve speed of dropping water, or pressure flush, not easy-to-use mosquito forceps or knife blade are scratched and are scraped; Micropore blocks conducting limit, available epidural anesthesia seal wire limit pressure flush if drip between cutter head; End of operation should be closed the star wheel that drips.This electric knife also can be tried out the part excision in spleen.
This utility model is skillfully constructed, and novel structure can make full use of existing medical resource, improves the utilization rate of basic hospital bipolar coagulation machine.Easy and simple to handle, can finish smoothly with the Single-pole electric knife compounding practice and to cut liver surgery, complicated originally liver cutting operation is become simply save time.Go out insufficiency of blood when cutting liver, can need not blocking-up and go into liver blood stream in the following hemostasis of cutting edge of direct-view, the liver function injury of having avoided blocking-up liver blood stream to be caused has improved operation safety, and normal liver tissue is not had secondary damage, and no trunk damages and the avoiding of massive hemorrhage.Owing to be that passivity is cut liver, fulgerize little blood vessel and hepatic sinusoid make hemorrhage obvious minimizing, keep than trunk and bile duct, cut off for further ligation and give security.Be furnished with dripping device, reduce tissue temperature between cutter head when electricity coagulates, reduce carbonized, do not make cutter head and tissue adhesion form eschar, make the anthemorrhagic performance lasting stability.This apparatus is suitable for large, medium and small hospital wide popularization and application.
