Description

一种多功能电刀头Multifunctional electric cutter head 技术领域Technical field
本实用新型涉及一种医疗器械，尤其是一种手术过程中使用的多功能电刀头。The utility model relates to a medical device, in particular to a multifunctional electric cutter head used in a surgical procedure.
背景技术Background technique
高频电刀越来越多地应用在各种内窥镜手术中，如:腹腔镜、前列腺切镜、胃镜、膀胱镜、宫腔镜等手术中。由于高频电刀可同时进行切割和凝血，在机械手术刀难以进入和实施的手术中(如:腹部管道结扎、前列腺尿道肿物切除)得以普遍应用。高频电刀突出的凝血效果，使它广泛应用在弥漫性渗血部位如肝脏、脾脏、甲状腺、乳腺、肺部手术中。High-frequency electrosurgical knives are increasingly used in a variety of endoscopic procedures, such as laparoscopic, prostatectomy, gastroscope, cystoscopy, hysteroscopy and other operations. Because the high-frequency electrosurgical knife can simultaneously cut and coagulate, it is widely used in the surgery that the mechanical scalpel is difficult to enter and implement (such as abdominal tube ligation, prostatic urethral tumor resection). The high-frequency electrosurgical prominence of coagulation makes it widely used in diffuse oozing sites such as liver, spleen, thyroid, breast, and lung surgery.
高频电刀有两种主要的工作模式:单极和双极。在单极模式中，用一完整的电路来切割和凝固组织，该电路由高频电刀内的高频发生器、病人极板、接连导线和电极组成。在大多数的应用中，电流通过有效导线和电极穿过病人，再由病人极板及其导线返回高频电刀的发生器。能摧毁病变组织的高频电刀的加热效应，并不是由加热电极或刀头造成的，像电烧灼器那样。它是将高电流密度的高频电流聚集起来，直接摧毁处于与有效电极尖端相接触一点下的组织的。当与有效电极相接触或相邻近的组织或细胞的温度上升到细胞中的蛋白质变性的时候，便产生凝血，这种精确的外科效果是由波形、电压、电流、组织的类型和电极的形状及大小来决定的。High-frequency electric knives have two main modes of operation: unipolar and bipolar. In unipolar mode, a complete circuit is used to cut and solidify the tissue, which consists of a high frequency generator in the high frequency electrosurgical unit, patient plates, connecting wires, and electrodes. In most applications, current is passed through the patient through active leads and electrodes, and the patient plate and its leads are returned to the generator of the high frequency electrosurgical unit. The heating effect of a high-frequency electrosurgical knife that can destroy a diseased tissue is not caused by a heated electrode or a cutter head, like an electric cautery. It concentrates the high current density of high currents and directly destroys the tissue at a point in contact with the tip of the effective electrode. Coagulation occurs when the temperature of a tissue or cell that is in contact with or adjacent to an effective electrode rises to the protein in the cell. This precise surgical effect is caused by the waveform, voltage, current, type of tissue, and electrode. The shape and size are determined.
常用的高频电刀的电刀头最常见的配置为通常以“L”或“J”形状提供的“钩”电刀头，能够在烧灼之前操作和提拉组织(钩)的优点，从而能够清楚地显示手术需要；还有表面较宽以灼烧更大的组织区域或更大的出血来源的“铲”形电刀头。通常，在手术期间，为进入解剖切割面器官和血管，大多数外科医生均需要完整更换电刀头，以处理血管局部出血、较大面积凝结、无血分离和摆动组织及粘连。但是手术中更换电刀头具有潜在的危险，耽误治疗出血部位的时间，同时增加了大量的额外费用。The most common configuration of the commonly used electrosurgical cutters is the "hook" electric cutter head usually provided in the shape of "L" or "J", which can manipulate and lift the structure (hook) before cauterization, thereby It is possible to clearly show the need for surgery; there is also a "shovel"-shaped electric cutter head with a wide surface to burn a larger tissue area or a larger source of bleeding. Typically, during surgery, most surgeons require complete replacement of the electric cutter head to access the anatomical cutting surface organs and blood vessels to treat localized blood vessel bleeding, large area condensation, bloodless separation, and oscillating tissue and adhesion. However, the replacement of the electric cutter head during surgery is potentially dangerous, delaying the treatment of the bleeding site, and adding a large amount of additional costs.

实施例1Example 1
现代外科中电外科手术已广泛普及，电外科手术系利用高频电流来切开组织，达到止血的效果。电刀是外科常用的设备，其融合切割、分离、止血为一体，使这些分开性的操作同时完成，减少结扎或缝合止血的频度，可大大缩短手术时间。电刀系利用高频电流来切开组织和达到止血的效果。电刀在手术中可达到以下几种功能：(1)干燥：低功率凝结不需要电光；(2)切割：释放电光，对组织有切割效果；(3)凝固：电光对组织不会割伤，可用于止血和烧焦组织；(4)混切：同时起切割及止血作用。Electrosurgery has been widely used in modern surgery, and electrosurgery uses high-frequency current to cut tissue to achieve hemostasis. The electrosurgical unit is a commonly used equipment for surgery. It combines cutting, separating and hemostasis to complete these separate operations at the same time, reducing the frequency of ligation or suturing to stop bleeding, which can greatly shorten the operation time. The electrosurgical system uses high-frequency current to cut tissue and achieve hemostasis. The electric knife can achieve the following functions during surgery: (1) Drying: low-power condensation does not require electro-optic; (2) cutting: discharge of electro-optic, cutting effect on the tissue; (3) solidification: electro-optic will not cut the tissue It can be used for hemostasis and charred tissue; (4) Mixed cutting: simultaneous cutting and hemostasis.
常用电刀结构由高频电子发生器、高频电极板、高频电刀头三部分组成，老式电刀还有脚踏开关。高频电子发生器和电极板在手术开始前由巡回护士准备妥当，电极板有硬极板和软极板，软极板与患者接触紧密，电阻为0，使用中不易产生烧灼伤，现多应用软极板；高频电子发生器的电能等级调节至关重要，电能等级是依据各种不同的外科手术、医生技巧及电刀头的不同而定。在普通外科手术中一般单极输出，电能高定原则是：(1)低电能，用于细小出血的电凝止血，粘连的分离，中小血管的的解剖分离；(2)中电能，较大出血的电凝止血，腹腔内脏器、组织的切割、游离；(3)高电能，肝脏组织的切割，癌细胞切除(如乳腺癌根治术)。电能的设定还需要依据主刀医生的个人经验来设定。手术者操纵高频电刀头，电刀头上有二个控制开关按扭，上方的主管电凝，下方的主管电切，电凝主要用于点状止血，一般直径1mm以下血管电凝可以控制出血，电切主要用于切割组织兼有止血功能，高频电刀头的电极有长短之分，长电极用于深部组织操作，短电极用于浅部组织操作。The commonly used electrosurgical structure consists of a high-frequency electronic generator, a high-frequency electrode plate, and a high-frequency electric knife head. The old-fashioned electric knife also has a foot switch. The high-frequency electron generator and electrode plate are prepared by the roving nurse before the operation begins. The electrode plate has a hard plate and a soft plate. The soft plate is in close contact with the patient, and the resistance is 0. It is not easy to cause burns during use. The application of soft plates; the regulation of the power level of high-frequency electronic generators is essential, and the power level is based on various surgical procedures, doctor's skills and electric cutter heads. In general surgery, the general unipolar output, the principle of high energy is: (1) low electrical energy, electrocoagulation for fine bleeding, hemostasis, separation of adhesions, anatomical separation of small and medium blood vessels; (2) medium electrical energy, large bleeding Electrocoagulation to stop bleeding, abdominal organs, tissue cutting, free; (3) high electrical energy, liver tissue cutting, cancer cell resection (such as radical mastectomy). The setting of electric energy also needs to be set according to the personal experience of the surgeon. The operator manipulates the high-frequency electric cutter head. There are two control switch buttons on the electric cutter head. The upper main tube is electrocoagulated, and the lower main tube is electrically cut. The electrocoagulation is mainly used for point-shaped hemostasis. Generally, the blood vessel can be coagulated below 1 mm in diameter. Control bleeding, electric cutting is mainly used to cut tissue and hemostasis function, the electrode of high-frequency electric knife head has length and length, long electrode is used for deep tissue operation, short electrode is used for shallow tissue operation.
应用高频电刀的优点是手术操作中不需要很多的结扎，切割和止血一气呵成，切口内不留异物，术野干净清晰，操作迅速，特别是长电极有利于深部(如 盆腔)的操作。The advantage of applying high-frequency electrosurgical knife is that it does not require a lot of ligation in the operation, cutting and hemostasis in one go, no foreign matter is left in the incision, the surgical field is clean and clear, and the operation is rapid, especially the long electrode is beneficial to the deep part (such as The operation of the pelvic cavity).

Brill E lectricity is produced when valence electrons are freed from atoms of conductive materials. When these electrons are set in motion in the same direction an electric current (I) is produced that is measured in amperes. Opposite charges on the ends of the conductor cause the elec-trons to flow in one direction toward the positive terminal. The differ-ence in potential between the positive and negative poles provides the electromotive force (voltage) to drive the current through the conductor (Figure 1).
