Abstract
The invention discloses a soft lenses mucous membrane resection special-purpose bipolar electrotome comprising an outer sleeve and a wire arranged in the outer sleeve; the end of the wire extends outside the outer sleeve, and is connected with a pole; the pole is a bidirectional electrode structure comprising a positive electrode and a negative electrode; the bipolar electrotome mode provides high frequency electric energy on body tissues through two tips of the bidirectional electrode structure, so the blood vessel between the two ends of the bipolar can be dehydrated and solidified, haemostasis purpose is realized, and cutting purpose can be realized through cytoplasm vaporization; the working scope is limited between two ends of the positive negative electrodes, so damage level and influence scope on the body tissue can be much smaller when compared with the single pole mode, thus obviously reducing bleeding and perforation rate; the bipolar electrotome of a soft lenses clamp channel can enlarge the soft lenses treatment scope, so the soft lenses can be higher in efficiency, and smaller in risk.
Description
Technical field
The present invention relates to field of medical technology, be 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, the present invention comes therefrom。
Summary of the invention
The Single-pole electric knife that the technical problem to be solved is the soft lens overcoming prior art also exists the hemorrhage risk waiting severe complication of perforation, it is provided that a kind of various types of bipolar electric knife clamping road feature suitable in soft lens。
For solving the technical problem of above-mentioned first aspect, the present invention provides the special bipolar electric knife of mucosa resection under a kind of soft lens, it includes trocar sheath and the wire being located in described trocar sheath, and described wire connects electrode at the end extending trocar sheath, it is characterized in that, described electrode is the bipolar electrode structure including anelectrode and negative electrode。
In currently preferred technical scheme, between described anelectrode and negative electrode, it is not provided with attachment structure。
In currently preferred technical scheme, negative electrode one end of described bipolar electrode structure is perpendicular straight configuration, and its another end connects wire and is connected to the negative pole of power supply via trocar sheath；Described positive electricity is extremely located at arc or the annular of the suitable radius distance in negative electrode periphery, and its two end connects wire respectively and is connected to the positive pole of power supply via trocar sheath。
In currently preferred technical scheme, anelectrode and the negative electrode of described bipolar electrode structure are positioned at approximately the same plane。
In currently preferred technical scheme, connected by covered wire between described anelectrode and negative electrode。
In currently preferred technical scheme, the linear structure that described anelectrode and negative electricity are extremely parallel to each other, one end of described anelectrode and negative electrode is connected with described covered wire respectively, and their other end connects wire respectively and is connected to the both positive and negative polarity of power supply via trocar sheath。
In currently preferred technical scheme, 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 currently preferred technical scheme, in described anelectrode and negative electrode are generally aligned in the same plane。
In currently preferred technical scheme, described anelectrode and negative electrode are not in same plane, for dissymmetrical structure。
A second aspect of the present invention 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.。
The bipolar electric cutting die formula of the present invention 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 present invention design clamps road by soft lens makes soft lens therapeutic domain wider, and in hgher efficiency, risk is less。
The bipolar electric knife of the present invention 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, the invention has significantly hemorrhage, punching rate and reduces when hollow organ mucosas such as resection cavity shape organ such as stomach, intestinal, esophagus, uterus, vagina, bladders, advantage simple to operate。
