Description
Technical field
This utility model relates to field of medical technology, is specifically related to a kind of medical apparatus and instruments, particularly to the special bipolar electric knife of mucosa resection under a kind of soft lens.
Background technology
In soft lens, mucosa resection technology all applies Single-pole electric knife: if IT cutter, Hook cutter, triangular knife etc. are all the main tool of soft lens technology such as ESD, ESE, STER.But it has been observed that perforation and hemorrhage be the main complication of above technology and failed reason.Cause above reason to be because Single-pole electric knife and there is design defect: Single-pole electric knife is with electric knife for a pole, and the tissue of contact and health are another pole carrier；Require electric knife pole necessary pin-point accuracy when contact tissue after energising, otherwise there will be resection organization and cross shallow and cross deep phenomenon, excise especially for digestive tract tissue adherence or submucous tissue and perforated phenomenon easily occurs.Owing to being used for organizing cutting to need TURP pattern, coagulation pattern need to be used for blood vessel cutting, therefore, often have coagulation and TURP separately in Single-pole electric knife is applied or mixing applicable cases.Due to tissue and microvascular tissue mixing extremely difficult resolution, therefore there is the arterial vascular risk of TURP when electricity cutting tissue, what cause occurring being difficult to stopping is hemorrhage.It addition, when coagulation vascular time is long, digestive canal wall coagulation necrosis around can be caused, and then brings out Delayed onset perforation and hemorrhage.In order to reduce hemorrhage and perforation accident, usually applying water cushion technology clinically, namely under mucosa, a small amount of hypertonic saline of open texture pad is with chorista spacing, although this measure decreases complication to a certain extent；But still have the incidence rate of up to 20-40% complication.
In monopolar mode, cutting and solidified structure with a complete circuit, this circuit is made up of the high frequency generator in high frequency electric knife, patient's pole plate, in succession wire and electrode.In most application, electric current is by active wires and electrode traverse patient, then is returned the generator of high frequency electric knife by patient's pole plate and wire thereof.So perforation very easily occurring when the very thin tissues such as cutting hollow organ such as gastrointestinal mucous membrane of esophagus usually occur, in order to avoid perforation application cutting current very easily injured blood vessel causes hemorrhage.Patient's pole plate in single-pole device contacted not at that time, may result in the side effect burnt in contact area.
Therefore, when prior art, in order to reduce the problem of operating difficulty and the incidence rate reducing the complication such as hemorrhage and perforation, this utility model comes therefrom.

In the preferred technical scheme of this utility model, described anelectrode and negative electrode are formed as plow-shape structure, and one end of described anelectrode and negative electrode is connected with described covered wire respectively, and their other end wire respectively is connected to the both positive and negative polarity of power supply via trocar sheath.
In the preferred technical scheme of this utility model, in described anelectrode and negative electrode are generally aligned in the same plane.
In the preferred technical scheme of this utility model, described anelectrode and negative electrode are not in same plane, for dissymmetrical structure.
Second aspect of the present utility model provides a kind of high frequency electro surgical unit being provided with above-mentioned bipolar electric knife.
Described operating theater instruments includes the soft lens such as the high frequency electric knife of gastroscope, intestinal mirror, enteroscope, duodenoscope, ureteroscope, cystoscope, bronchoscope etc..
Bipolar electric cutting die formula of the present utility model is to provide high-frequency electrical energy by two tips of bipolar electrode (structure electrode such as needle electrode, tweezers or shears) to body tissue, the blood vessel dehydration between bipolar two ends is made to solidify, reach hemostasis purpose, arrive cutting purpose by Cytoplasm vaporization；Its sphere of action is only limited between positive and negative electrode two ends, and degree of injury and coverage to body tissue are much smaller more than unipolar fashion, it is possible to significantly reduce hemorrhage and perforation incidence rate.The bipolar electric knife that this utility model design clamps road by soft lens makes soft lens therapeutic domain wider, and in hgher efficiency, risk is less.
The bipolar electric knife of this utility model is for mucosa resection treatment under soft lens (such as soft lens such as gastroscope, intestinal mirror, enteroscope, ureteroscope, bronchoscopies).Compared with existing Single-pole electric knife technology, this utility model is created has significantly hemorrhage, punching rate minimizing, advantage simple to operate when hollow organ mucosas such as resection cavity shape organ such as stomach, intestinal, esophagus, uterus, vagina, bladders.
