Abstract

The invention discloses a scalpel for electrosurgery and an electrosurgery system. The scalpel for electrosurgery comprises a scalpel handle and a scalpel head detachably installed on the scalpel handle. Tthe scalpel head comprises an outer conductor, an insulating medium, an inner conductor and a positive electrode, wherein the outer end of the outer conductor is provided with an arc incision, and both ends of the arc incision are respectively upper outer electrode and lower outer electrode; the insulating medium and the inner conductor are successively and fixedly connected inside the outer conductor, the insulating medium is located between the outer conductor and the inner conductor, the inner conductor is used for releasing microwave signals to undergo surgery hemostasis; and the positive electrode is arranged on the outer conductor or the inner conductor and is used for releasing radio frequency signals to undergo surgery tissue incision; and a water duct is arranged on the outer conductor or in the insulating medium and is used for transferring normal saline to undergo tissue separation and/or cooling. The scalpel has the effect of complementing the advantages of three surgical instruments, namely radio frequency electric knife, medical water knife and microwave scalpel.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a scalpel for electrosurgery and an electrosurgery system. Background technique [0002] The separation, cutting and hemostasis of human tissue are the eternal themes in the surgical operation process. Due to the different working principles of electrosurgical instruments, the scalpels used in surgical operations mainly include: radio frequency electric scalpel, microwave scalpel, and medical water knife. They are just There are advantages in one of them, and combining them in a scalpel is the mainstream of development in the field of surgical equipment today. [0003] Radio frequency surgery is a non-invasive method for cutting soft tissue. The 4MHz radio frequency waves emitted by the surgical electrode pass through the tissue to generate resistance, and the cells in contact will generate heat by themselves. The heat in the radio frequency channel causes the water molecules ...
