Abstract
The utility model discloses a high-frequent electric knife blade, including a knife root part, a knife blade part and an extension part arranged between the knife root part and the knife blade part; the extension part takes a shape of slender strip, the knife blade part takes a shape of ' ', the knife root part, the extension part and the knife blade part are combined to be a whole. As the blade extends the length, the blade is especially applicable to the small incision operations, such as the gallbladder resection; the ' '-shaped design of the knife blade part can not block the vision of the surgeons by the knife root part, so the surgeons can clearly see the cutting situation of the incision site by the knife blade part, which is beneficial to the achievement of better effects of the operations.
Description
Technical field
This utility model relates to medical surgical knife, more specifically refers to a kind of high frequency electric knife blade.
Background technology
High frequency electric knife is with the outfan frequency height that it was had, the characteristics that effective area is little, electric current density is big, be widely used in all kinds of operations of hospital, as radical mastectomy, thyroid tumor enucleation, extremity operation and all kinds of operations of abdominal part, the action principle of this cutter and structure are asked foreknowledge Fig. 1, electric knife handle 1 is connected to high frequency generator 3 one outfans by former source electric wire 2, electric knife blade 4 is installed on the electric knife handle 1 (is called 11 trumpeter's art blades, see Fig. 2), loop electrode 5 connects another outfan of high frequency generator 3 by loop electrode lead 6.This electric knife can produce enough heats and finish cutting and hemostatic effect with the part within a short period of time.Electric knife blade 4 comprises cutter root and blade part, cutter root and blade part are connected as a single entity, the cutter root is rectangular-shaped, blade part is a triangle, blade is forward tip, it is better that electric knife blade 4 is used for the surgical effect of big otch, and for small incision surgery, as the gallbladder removal operation, the length of blade is not enough, and effect is relatively poor, and in use, the cutter root blocks surgical sight line easily, and the surgeon can't see the cutting situation of blade part to deep tissue clearly, easily causes iatrogenic injury and influences the effect of operation.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist at traditional high frequency electric knife blade, and a kind of improved high frequency electric knife blade is provided.
To achieve these goals, this utility model adopts following technical scheme: this high frequency electric knife blade comprises cutter root and blade part, wherein, an extension is arranged between cutter root and blade part, and extension is an elongated strip, and blade part is one
Shape, cutter root, extension, blade part are connected as a single entity.
Described cutter root is a rectangular shape for one section, and another section is a triangle.
The length of described extension is 3-4cm.
Because this utility model blade has additional an extension between cutter root and blade part, extension is an elongated strip, the length of the blade that extended, and this blade is specially adapted in the operation of little otch, as gallbladder removal hands art; Blade part
The design of shape makes surgical sight line can not blocked by the cutter root, and the doctor can clearly see the cutting situation of blade part to deep tissue clearly, helps operation and obtains better effect.
Description of drawings
Fig. 1 is high frequency electric knife sketch map in operation.
Fig. 2 is traditional high frequency electric knife blade structure sketch map.
Fig. 3 is this utility model electric knife blade structure sketch map.
The specific embodiment
It is please structure shown in Figure 3,
Described cutter root 41 can be divided into two-stage nitration, and one section is rectangular shape, and another section is a triangle, and in the present embodiment, this section is roughly a right angle triangle.
The length of described extension is 3-4cm.
In fact, blade 4 of the present utility model be on the basis of former conventional blades blade part, extend one elongated
Shape bar, right part then are blade part 42 of the present utility model.
When using the electric knife blade to carry out the gallbladder removal operation, separate in separation and to cut cystic duct and cystic artery, after giving cover bundle and ligation respectively, this blade is inserted handle of a knife 1, be used to separate the gallbladder seromuscular layer, the assistant with in curved or big curved hemostatic forceps separate seromuscular layer, the blade of operator person's electricity consumption cutter blade 4 cuts under energized normally, scrub nurse helps to absorb smog with suction pump, little though hit, but clear visual field can be finished operation process under direct-view, the little blood vessel on the gallbladder bed all can electric coagulation hemostasis.Use this power blade operation safety, quick, hemorrhage its advantage that is such as little.
The thickness of electric knife blade of the present utility model is identical with traditional blade thickness, because blade part does not resemble traditional blade the sharp knife sword is arranged, this blade curtana sword is difficult for blunt, so can use repeatedly, need not to worry blunt.
