Description

Electric knife

The invention relates to an electric knife, in particular to a medical electric knife.

Electric knife is a kind of scalpel. It is a tool for cutting or cauterizing tissue by electric burning. Its basic principle is to use radio frequency to pass through the human body and generate high heat through the impedance in the human tissue to destroy the tissue, thereby achieving cutting and coagulation. Its function. The common electric knife is in the shape of a pen, one end is pointed, and the other end is connected to a power source. After the power is turned on, the tip will emit high-frequency current.

Lighting is very important in the operation of the operation. In order to have a clear field of vision when using the electric knife, it is known that the electric knife is equipped with a light source on the side near its tip, so that the light can continue to align with the movement of the electric knife. The surrounding organization provides lighting. However, since the light source is arranged on one side of the electric knife, other locations where the electric knife is not provided with a light source cannot provide illumination for its relative tissue position, resulting in inconvenience in operation.

At present, a combination of a light source and an electric knife has been created to achieve a brighter operating state during surgery. However, in many known technologies, the power supply configuration design of the light source and the electric knife is synchronized with the electric power supply line of the electric knife. In this design, if the original single line fails when the entire electric knife is unavailable, this creative design is an independent battery holder to supply the light source. In case the original electric knife circuit is unavailable, the light source still has normal use performance, and The other part of the known technology is to design another circuit to supply the light source, and it is necessary to bypass the multiple designed light source circuits during the operation to cause surgical obstacles. In order to achieve better surgical use, this work uses an independent power supply. The combination of the supply and the light source can control the allocation of light and shade without the need to configure additional lines, which improves the efficiency of the operation. In addition, the design of the creative pen body does not hinder the line of sight during operation due to the addition of a light source and an independent battery holder. The design of the front light source of the pen body adopts an arc type to make the entire electric knife and pen still integrated. There is no obstruction due to the design parts that must be prominent in the design of the light source.

In addition, there are still many electro-knife techniques. Such as the Chinese Utility Model Patent Bulletin No. CN2555003Y, this conventional technology is designed as an independent battery holder power supply light source design, which is completely different from this conventional technology. In addition, a transparent cover is designed at the source end of the electric knife light to illuminate the light source forward.

Another example is Chinese Invention Patent Publication No. CN104434305A. This conventional technology light source design 2-1, 2-2. Each triangle protrusion extends upward from the pen body, and it may cause obstruction of sight when it is operated again, and the power supply The supply is the same power line for the electric knife. You cannot choose the switch of the light source yourself. Compared with the original design of the lamp source and the electric knife body, the front end is a semi-circular arc design, so there is no obstruction in sight during operation, and the independent lamp source control can control the use of the lamp source.

Another example is the Chinese Utility Model Patent Bulletin No. CN201743764U. Although this conventional technical design is the same as the original design direction, this original design has internal circuit configuration design, and the light source power supply is an independent supply method. The lamp source circuit configuration is quite different.

Another example is the Chinese Utility Model Patent Bulletin No. CN202036311U. Although this conventional technology design light source is similar to this creative design, the light source circuit configuration is completely different. This conventional technology light source circuit is connected with the electric knife itself. The creative design is an independent battery supply method and the light source can be switched on and off by itself to achieve the best working effect.

Another example is Chinese Utility Model Patent Bulletin No. CN203953803U. This conventional technology does not mention the internal circuit configuration of the electric knife, and the light source circuit configuration is also connected in parallel with the electric knife. This design is completely different from the original independent battery supply lamp design.

Another example is the Chinese Utility Model Patent Bulletin No. CN203953804U. Although this conventional technology is also designed to be at the front end, the light source configuration is an independent line that needs to be connected to power supply. This creative design provides the light source and circuit configuration for the independent battery holder design. Also avoid the working end of the electric knife, the light source will not be affected by the heat of the electric knife during the operation.

Another example is China Utility Model Patent Bulletin No. CN207012240U. This conventional technology is designed in parallel to the supply of electric light source. It cannot be used to switch light source on and off independently. Effect.

Another example is Chinese Utility Model Patent Bulletin No. CN202036311U. The light source of this conventional technology is also in parallel with the electric knife. It cannot be used to switch the light source independently. The circuit board design and configuration are also different from this creation.

Therefore, this creative department provides an electric knife that can provide sufficient lighting when operating.

The technical means used to solve the problems of the conventional technology in this creation is to provide an electric knife including: a blade member; and a holding member sleeved on the outside of the blade member, one end of which is electrically Burning end, the blade member is exposed from the electric burning end, wherein the electric burning end is formed as a transparent electric burning end, a lamp source is disposed in the transparent electric burning end, and the light source is electrically connected to the lamp source.
