Definitions

  • 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.
  • a bipolar high-frequency coagulation hemostasis device in the form of a tweezers, that is, an electric knife is used.
  • 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.
  • 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
  • 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.
  • the tweezers 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.

Abstract

L'invention vise à proposer un scalpel électrique de type manuel qui est d'utilisation très souple et peut être utilisé dans les services hospitaliers, dans des cliniques de soins externes ou même à l'extérieur. A cet effet, l'invention porte sur un scalpel électrique qui comprend des pinces (2) électriquement connectées à un corps principal (1) dans lequel un circuit haute fréquence et une batterie sont incorporés. Il en résulte que le scalpel électrique est sans fil et portatif, de telle sorte que le dispositif entier peut être tenu dans la main lorsqu'il est utilisé.
