Description

ハンディ形電気メスHandy type electric knife
　本発明は、外科手術などにおいて迅速に患部の止血を行うバイポーラ形の高周波凝固止血装置、いわゆる電気メスに関するものである。 The present invention relates to a bipolar high-frequency coagulation hemostasis device that quickly stops hemostasis in a surgical operation or the like, that is, a so-called electric knife.
　外科手術などにおいて、迅速に患部の止血ならびに組織の接着を行うことが重要であるが、この目的のため、ピンセット形をしたバイポーラ形高周波凝固止血装置、すなわち電気メスが用いられる。バイポーラ形は、電源装置で発生させた高周波電流をピンセットの先端間に流し、ピンセットで挟んだ組織に通電させることにより凝固、止血を行うもので、特許文献１などに記載がある。 In surgery and the like, it is important to quickly stop the affected area and adhere the tissue. For this purpose, a bipolar high-frequency coagulation hemostasis device in the form of a tweezers, that is, an electric knife is used. In the bipolar type, coagulation and hemostasis are performed by flowing a high-frequency current generated by a power supply device between tips of tweezers and energizing a tissue sandwiched between tweezers.
　　従来のバイポーラ形高周波電気メスは、図６に示すごとく、電源コンセント８により100V電源に接続して高周波を発生する本体１と、組織を挟んで凝固止血するための導電性のピンセット２とが電線９でつながっていて、必要に応じ足下スイッチ１０により通電する方式である。この方式は、主として手術室での使用を前提としたものであるため可搬性に乏しく、取り回しの自由度が低く、使用場所に制限がある。
特開２００８－１７９１７号公報 As shown in FIG. 6, a conventional bipolar high-frequency electric knife has a main body 1 that generates a high frequency by being connected to a 100 V power source by a power outlet 8, and a conductive tweezers 2 for coagulation and hemostasis across tissue. 9 is connected and is energized by the foot switch 10 as necessary. This method is mainly based on the premise that it is used in an operating room, so it is not portable, has a low degree of freedom in handling, and has a limited place of use.
JP 2008-17917 A
　　医療の進歩に伴い、病棟や外来もしくは野外（事故や災害時における救急救命など）でも使用可能で、取り回し自由度の高いハンディタイプの高周波凝固止血装置が必要となっている。 With the advancement of medical care, a handy type high-frequency coagulation and hemostasis device that can be used in hospital wards, outpatients or outdoors (emergency lifesaving in the event of an accident or disaster) and has a high degree of freedom in handling is required.
　この目的を達成するため、本発明においては導電性のピンセットと本体とを電線でつなぐ方式ではなく、ピンセットを直接本体に取り付けるハンディ形とした。
　　すなわち、本発明のハンディ形電気メスは、高周波回路および電池を内蔵した本体と、これに電気的に接続する導電性のピンセットとからなり、装置全体を手に持って使用でき、ポータブルでコードレスの電気メスを実現したものである。 In order to achieve this object, the present invention adopts a handy type in which tweezers are directly attached to the main body, rather than a method of connecting the conductive tweezers and the main body with an electric wire.
That is, the hand-held electric knife of the present invention comprises a main body containing a high-frequency circuit and a battery, and conductive tweezers electrically connected to the main body. An electric knife is realized.
　手の大きさや指の長さなどで、使用感に個人差が生じるが、ピンセットをある程度回転できるようにして、術者が使用しやすい角度に調節することにより個人差を吸収でき、かつ取り扱い自由度が大きくなる。角度の回転は本体とピンセットとの取り付け部分で行ってもよいし、本体そのものに回転部を設けてもよい。
　また、本体に光源を内蔵しておけば、創部が深い場合などに照明をあてながら操作できるので有用である。 There are individual differences in the feeling of use depending on the size of the hand and the length of the fingers, etc., but the individual differences can be absorbed by adjusting the angle so that the surgeon can use it by allowing the tweezers to rotate to some extent, and handling is free The degree is increased. The rotation of the angle may be performed at the attachment portion between the main body and the tweezers, or a rotation portion may be provided on the main body itself.
In addition, if a light source is built in the main body, it is useful because it can be operated with illumination when the wound is deep.
　なお、ピンセットを取り外し可能にすることにより、アドソン型や耳鼻科用など様々なタイプのピンセットと交換して、様々な部位や組織の凝固止血用に使用することができる。 In addition, by making the tweezers removable, it can be used for coagulation and hemostasis of various parts and tissues by exchanging with various types of tweezers such as for Adson type and otolaryngology.
　　以上のごとく、本発明においては、電源に電池を使用することにより、ポータブルでコードレスのバイポーラー形電気メスが実現し、病棟のみならず外来もしくは野外（事故や災害時における救急救命など）での止血が可能となるという、すぐれた効果を奏する。 As described above, in the present invention, a portable and cordless bipolar electric scalpel is realized by using a battery as a power source. Excellent effect that hemostasis is possible.
　以下、本発明の実施形態について詳しく説明する。 Hereinafter, embodiments of the present invention will be described in detail.
　図１は実施例のバイポーラ形電気メスの外観図である。高周波回路および電池を内蔵した本体１に導電性のピンセット２が電気的に接続されている。３は回転部で、ピンセット２は本体１に対してここを中心にある程度回転できるようになっている。４は通電スイッチ、５は光源スイッチである。
　図２は本実施例の側面図で、本体１に内蔵されている高周波回路７および電池８を点線で示す。これらは最近の半導体技術および電池技術の発達により実現出来たもので、特に周波数1.7MHz用に2cm×2cm×1cmの超小型トランスが開発されたことが大きく寄与している。これに2000mAhのニッケル水素電池5本を組み合わせると、15W程度の出力で30分ほど電気メスを使用でき、外来での手術等には十分に使用可能である。なお、周波数としては、300kHzから5MHzまでの範囲が使用でき、電池としては乾電池も含めた各種小型電池が使用可能であるが、大容量で内部抵抗の小さい電池の使用が装置の小型化に有効である。 FIG. 1 is an external view of a bipolar electric knife of the embodiment. Conductive tweezers 2 are electrically connected to a main body 1 containing a high-frequency circuit and a battery. Reference numeral 3 denotes a rotating portion, and the tweezers 2 can be rotated to a certain extent with respect to the main body 1. 4 is an energizing switch, and 5 is a light source switch.
FIG. 2 is a side view of the present embodiment, and the high-frequency circuit 7 and the battery 8 built in the main body 1 are indicated by dotted lines. These have been realized by recent developments in semiconductor technology and battery technology, and the development of ultra-small transformers of 2cm x 2cm x 1cm especially for the frequency of 1.7MHz contributed greatly. When combined with five 2000mAh nickel-metal hydride batteries, an electric scalpel can be used for about 30 minutes at an output of about 15W, which can be used for outpatient surgery. The frequency range from 300 kHz to 5 MHz can be used, and various small batteries including dry batteries can be used. However, the use of batteries with large capacity and low internal resistance is effective for downsizing the device. It is.
　　図３は実施例の電気メスの使用状態を示す斜視図である。本体１を片手で握り、拇指と人差し指でピンセット２を操作し、残りの指で通電スイッチ４を操作する。ピンセット２先端で出血部位の組織をつまみ、通電スイッチ４を押すとピンセット２の先端間に高周波電流が流れ、つまんだ部分の組織が凝固され、止血される。
　　図４は非使用時の状態である。回転部３を中心にピンセット２を反対側に折り畳むことにより、滅菌時や保存時などにコンパクトで場所をとらないため便利である。 FIG. 3 is a perspective view showing a usage state of the electric knife of the embodiment. Hold the main body 1 with one hand, operate the tweezers 2 with the thumb and index finger, and operate the energizing switch 4 with the remaining fingers. When the tissue at the bleeding site is pinched with the tip of the tweezers 2 and the energizing switch 4 is pressed, a high-frequency current flows between the tips of the tweezers 2, and the pinched tissue is coagulated and hemostatic.
FIG. 4 shows a non-use state. Folding the tweezers 2 around the rotating part 3 to the opposite side is convenient because it is compact and does not take up space during sterilization or storage.
　光源６は、光源スイッチ５を入れるとピンセット２の先端に光を照射できるようになっており、創部が深い場合などに照明をあてながら操作できるので有用である。
　実施例のピンセット２は脱着部９により取り外し可能である。取り外したときの状態を図５に示す。目的に応じてさまざまな形態のピンセットを交換して装着することにより、さまざまな部位や組織の止血用途に使用できる。 The light source 6 is useful because it can irradiate light to the tip of the tweezers 2 when the light source switch 5 is turned on, and can be operated while illuminating when the wound is deep.
The tweezers 2 of the embodiment can be removed by the detachable part 9. The state when removed is shown in FIG. By exchanging and mounting various types of tweezers according to the purpose, it can be used for hemostasis of various parts and tissues.
