Изобретение относитс к хирург ческим инструментам , примен емым дл бескровного рассечени тканей с помощью токов высокой частоты, а именно к биактивпым электрохирургическим инструментам.The invention relates to surgical instruments used for bloodless dissection of tissues using high frequency currents, namely bi-active electrosurgical instruments.
Известны биактнвные хирургическне ннструменты , содержащие подвижно сочлененные между собой бранши и электроды на рабочих концах бранш. При сведении бранш инструмента режущие новерхности проникают в ткани и бескровно рассекают их.Known bi-surgical surgical instruments containing movably articulated branches and electrodes at the working ends of the branches. While mixing the branches of the tool, cutting surfaces penetrate the tissue and dissect them without bloodshed.
Недостатком этих инструментов вл етс то, что режущие кромки электродов сход тс под угло.м, что приводит к иеравномерной плотности тока вдоль режущих кромок н, еледовательно , к неравномерному и неодновременному воздействию этих кромок на ткань.The disadvantage of these tools is that the cutting edges of the electrodes converge at an angle of 3 mm, which leads to a uniform current density along the cutting edges and, therefore, to uneven and non-simultaneous effects of these edges on the fabric.
С целью устранени этого недостатка в предлагаемом ннструмеитс подвижное сочленение выполнено в виде механизма, обеспечивающего параллельность бранш в процессе их сведени , например, посредством двух пар равнонлечих рычагов, соединенных .между собой посредине, с рабочими концами браищ - щариирно и со стебл .ми бранш - посредством ползунов.In order to eliminate this drawback, the movable joint in the proposed nnstrumeits is made in the form of a mechanism ensuring parallelism of the branches in the process of their reduction, for example, by means of two pairs of equal-arm levers connected between themselves in the middle, with working ends of braishch - sharyirno and with stem branches - through the sliders.
На фиг. 1 изображен предлагаелгый бнактивный электрохирургический инструмент в двух проекци х; на фиг. 2 - разрез по А-А на фиг. 1.FIG. 1 depicts a proposed baktivny electrosurgical instrument in two projections; in fig. 2 is a section along A-A in FIG. one.

Биактивный электрохирургический инструмент выполнен в виде ножшщ, имеющих подвижно сочлененные между собой бранщи 1. Сочленение бранш выполнено в виде шарнирiioro механизма, состо щего из двух пар равнонлечнх рычагов 2, скрепленных по це1ггру осью 3. Концы соответствующих рычагов шарHiipHoro механизма соединены ос ми. Кажда ось, соедин юща нижние концы рычагов 2, может скользнть, как иолзун, в прорези нижнего кронштейна 4, нриваренного с внешней стороны стебле бранш. Кажда ось, соедин ЕОща верхнне концы рычагов 2, находитс в отверстии верхнего кронште1 ша 5.The biactive electrosurgical instrument is made in the form of scissors, which have movably jointed branches 1. The junction of branches is made in the form of a hinge mechanism, consisting of two pairs of equally levers 2, fastened along the chain with axis 3. The ends of the corresponding levers of the HIipHoro mechanism are connected by axes. Each axis connecting the lower ends of the levers 2 may slide, like an i-slide, in the slot of the lower bracket 4, welded on the outside of the stem of the branch. Each axis, which connects the upper ends of the levers 2, is located in the hole of the upper bracket 5.
Такое ycTpoiicTBo шарнирного механизма обеспечивает свободное параллельное перемещение бранш и устран ет возможность их перекоса. У ннжнего каждой браиши приварено металлическое кольцо 6 дл пальцев руки, что иозвол ет раздвигать и сводить браншн с активными кончиками 7 и режущими кродмками 8.This ycTpoiicTBo of the hinge mechanism ensures free parallel movement of the branches and eliminates the possibility of their skewing. A metal ring 6 for the fingers of the hand is welded at the bottom of each brush, which makes it possible to expand and reduce the branch with the active tips 7 and the cutting edges 8.
Подвод тока к режущим кромкам инструмента осуществл етс при помощи покрытого изол цией токопровод щего стержн 9, который проходит внутрн соответствующей бранши по ее оси.The current is supplied to the cutting edges of the tool using an insulated conductive rod 9, which runs the internal branch in its axis.
Подвод тока к ннстру.менту производитс при noMOHiH двух проводов 10. Один конец каждого провода подключаетс к соответствующему выходному зажиму аппарата высокой частоты, другой заканчиваетс контактным гнездом 11. Стержень 9 фиксируетс внутри бранши при помощи двух изол ционных втулок верхней 12 и нижней 13. На верхний конец стержн навинчиваетс активный кончик с режущей к-ромкой, на нижний - контактна вилка 14, служаща одновременно дл подвода тока диатермии и дл фиксации стержн . Во избежание пробо тока на внутреннюю поверхность браншп наноситс слой изол ции, а на стержень, покрытый изол цией , дополнительно надеваетс изол ционна трубка 15. При помощи надетого на одну из бранш металлического кольца 16 с отход щи.м 01 него проводом 17 осуществл етс заземление ииструмента. Активные кончики инструмента , кроме режущих кромок, покрыты изол цией . При резекции ткани до включени тока одна режуща кромка 8 инструмента накладываетс на ткань сверху, а друга - снизу. Слегка вдавлива режущие кромки в ткан11, убеждаютс , что они на всем своем прот жепии наход тс в контакте с нею. Затем включают ток и медленно свод т бранщи, осунюствл благодар коагулирующему действию токов высокой частоты бескровный разрез ткани на всем прот жении режущих кромок. Во врем осуществлени разреза оси, соедин ющие нижние концы рычагов 2 щарнирного механизма, передвига сь в прорез х кронщтейнов 4 и враща сь вокруг оси 3, сближаютс . Сближаютс также верхние концы рычагов 2, поворачива сь в кронщтейнах 5. Это обеспечивает параллельное схождение бранщ с активными кончиками 7. При полном сведении бранщ режущие кромки заход т одна за другую на доли .мм, что способствует полному рассечению ткани. Короткое за.мыкание при этом не возникает, так как режун1,ие кромки попадают на покрытую изол цией часть активных кончиков, в результате чего происходит размыкание тока. Как закрытие, так и раскрытие инструмента нроисходит при параллельно.м движении бранщ и активных кончиков с режущими кромка.ми. Предлагаемый инструмент может рассекать все ткани, кроме костной. Предмет изобретени Биактивный электрохирургический инструмент , содержащий подвижно сочлененные между собой бранщи и электроды на рабочих концах бранш, отличающийс тем, что, с целью одновре.менного рассечени ткани и равномерной коагул ции стенок раны, подвижное сочленение бранш выполнено в виде механизма, обеспечиваюодего параллельность бранш в процессе их сведени , например, посредством двух пар равноплечих рычагов, соединенных между собой посредине, с рабочими концами бранщ - щарнирно и со стебл ми бранщ - посредством ползунов. - --ол: Д( The current is supplied to the power supply with noMOHiH of two wires 10. One end of each wire is connected to the corresponding output terminal of the high-frequency apparatus, the other ends with a pin socket 11. The rod 9 is fixed inside the branch using two insulating sleeves of the upper 12 and bottom 13. On the upper end of the rod is screwed on the active tip with the cutting ring, the lower end is the contact plug 14, which serves both to supply diathermy current and to fix the rod. In order to avoid current breakdown, an insulating layer is applied to the inner surface of the branch, and an insulating tube 15 is additionally attached to the rod covered with insulation. With the help of a metal ring 16 worn with one branch, a wire 17 is earthed and tools. The active tips of the instrument, except for the cutting edges, are insulated. When a tissue is resected before current is switched on, one cutting edge 8 of the instrument is applied to the fabric from above and the other from below. Slightly pressing in the cutting edges into the fabric 11, they are convinced that they are in contact with it throughout their entirety. Then the current is turned on and the branches are slowly reduced, sufed due to the coagulating action of high-frequency currents, a bloodless incision of the fabric throughout the cutting edges. During the incision, the axes connecting the lower ends of the arms 2 of the hinge mechanism, moving in the slots of the brackets 4 and rotating around the axis 3, approach each other. The upper ends of the levers 2 are also coming closer together, turning in the brackets 5. This ensures a parallel convergence of the jaws with the active tips 7. When the jaws are fully aligned, the cutting edges slide one after the other into fractions .mm, which contributes to the complete dissection of the fabric. A short closing does not occur in this case, since the rezhun1, ie edges fall on the insulated part of the active tips, as a result of which the current is opened. Both the closing and opening of the tool occur when there are parallel m movement of the branches and active tips with cutting edges. The proposed tool can dissect all tissues except the bone. The subject of the invention is a biactive electrosurgical instrument containing movably articulated branches and electrodes on the working ends of the branches, characterized in that, in order to simultaneously dissect the tissue and uniformly coagulate the walls of the wound, the movable articulation of the branches is made in the form of a mechanism ensuring the parallelism of the branches the process of combining them, for example, by means of two pairs of equal-arm levers, interconnected in the middle, with the working ends of the branches — sharned and with the stems of the branches — by means of sliders. - --ol: D (
