Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an electric scalpel device used when performing incisional surgery on a living body.

[Prior art]

An electric scalpel device uses high-frequency current to incise or coagulate living tissue, and is constructed as shown in FIG. 1. In the figure, reference numeral 1 denotes the main body of the electric scalpel device, which is configured with a high frequency generation circuit, and has a female cord connection terminal 3 for connecting between the high frequency generation circuit and the female cord plug 2 on the panel surface, and a high frequency generation circuit. A return electrode cord connecting terminal 5 is provided to connect between the circuit and the return electrode cord plug 4. The female cord plug 2 is connected to a female tip electrode 8 via a female cord 6 and a female holder 7, while the return electrode cord plug 4 is connected to a return electrode 10 via a return electrode cord 9. Then, by attaching the counter electrode plate 10 near the surgical site of the patient and applying the scalpel tip pole 8 to the surgical site, a high-frequency current generated in the high-frequency generation circuit flows to the contact portion between the scalpel tip pole 8 and the living body. This allows incision or coagulation of the surgical site of the living body.

[Problem that the invention attempts to solve]

Incidentally, in recent years, there has been an increase in opportunities for a plurality of surgical staff to simultaneously use two electric scalpel devices for one patient M, such as coronary artery bypass surgery and transplant surgery, as shown in FIG. In this case, the pair of return electrode plates 10 must be attached near each surgical site, but due to human error, the pair of return electrode plates 10 may be attached in the opposite direction, or the electric scalpel device main body 1 may be incorrectly attached. When moving, there is a risk that the pair of return electrodes 10 may be connected in reverse, or that the pair of scalpel tip electrodes 8 may cross and be replaced as shown by the dotted lines in FIG. 2 during surgery. If used in such conditions, burns may occur due to shunt of high-frequency current on the part of the patient M where the return electrode plate 10 is attached, or interference of high-frequency current may occur between the pair of scalpel tip electrodes 8, resulting in incision. Otherwise, problems such as coagulation not being performed normally may occur.

In view of the above-mentioned circumstances, this device can be used both when performing separate surgeries on two patients at the same time, and when performing surgeries on two parts of one patient at the same time, and can be used in one patient. It is possible to prevent various troubles when performing surgery on two parts of a patient. The purpose is to provide an electric scalpel device.
