Abstract

The utility model is the invention of improving the structure of existing public known electric knives, which is formed by that the mode that the knife blade and the knife handle of the original electric knife are fixedly connected is changed into the mode that the knife blade and a knife rod are made into integration or a knife body which is form by the connection of pin axles is fixed on the knife handle through a compression nut. The knife body can be in the shape of a straight rod or one end which is connected with the knife blade is in the shape of 90 DEG bend to meet the special requirement of different operations. The inner of the knife body and the knife handle of the electric knife of the utility model is additionally provided with an illuminating passage and a sucking passage. Through clinical verification, the improved electric knives enlarge the application range of electric knife operation, having convenient operation and portability.

Description

High-efficient electric knife

This utility model relates to the improvement to existing electric knife structure, belongs to the surgical operating instrument technical field.

In China, electric knife begins to be applied to clinical surgery operation in the fifties, over thirties years, improves owing to lack, and also can only be used for common surgical procedures, can't carry out deep and face operation in the body, and the efficient of performing the operation in addition is low, and the scope of application is limited.

The purpose of this utility model is to provide a kind of High-efficient electric knife, and its scope of application is wide, the function that has illumination simultaneously and attract.

Its structure of this utility model as shown in Figure 1, blade 1 and knife bar 3 are made as one or by bearing pin 6 cutter hub 7 that is formed by connecting, knife bar 3 is that insulating barrier 2 coats, knife bar 3 one ends are made plug, can insert handle of a knife 5 interpolation blocks, both are connected cutter hub 7 and handle of a knife 5 by a clamping nut 4, can adopt screw thread or bayonet lock to fix between clamping nut 4 and the handle of a knife 5, be that clamping nut 4 can screw in the handle of a knife 5 or inserts in the draw-in groove of handle of a knife 5, fix after rotating an angle, cutter hub 7 is seen Fig. 2 with handle of a knife 5 by the connection status of clamping nut 4, shown in 3, Fig. 4 is another kind of cutter hub 7 and handle of a knife 5 connection diagrams, its connected mode and Fig. 2, mode is identical shown in 3, just cutter hub 7 is near blade 1 one end vertical curve, this cutter hub is applicable to the intralaryngeal surgery to the patient, and its crooked end can stretch into the oral cavity to throat, above-mentioned Fig. 1, electric knife shown in 4 is specially adapted to department of eye and the operation of human body deep.

In order to reduce the surgical staff workload and to avoid because of the assorted trouble of bringing to operation of the many handss of people, especially under deep operation illumination deficiency and edge of a knife oozing of blood is more than, the petechia is difficult for looking for situation, can find out the petechia like clockwork and carry out electric coagulation hemostasis, attraction passage 8 and illumination channel 9 have been set up in the cutter hub 7 of the electric knife shown in Fig. 1,4, the inside of handle of a knife 5, its version is seen Fig. 6,7, attract passage 8 to be used for attracting, it is external to be about to body fluid and blood sucking-off that the edge of a knife oozes out, and it is connected with suction catheter by handle of a knife 5; Illumination channel 9 is sent cold light with light source and is shone operative site through the optical fibers conduction, like this when carrying out such as face and deep operation, the operation teacher can exempt to wear head lamp or frontal mirror, influence illumination in order to prevent that cutter hub 7 heads from obstructing the light, optical channel 9 openings are positioned at after blade 1 and knife bar 3 junctions, when in operation process, attracting program, attract in order to prevent that blade 1 from hindering, because the employing bearing pin is connected between blade 1 and the knife bar 3, blade 1 can rotate relative to knife bar 3 like this, simultaneously set up an escape 10 at cutter hub 7 top cutters 1 one end position places, as long as the operation teacher is used in reference to escape 10 is gone in blade 1 turnover, can normally attract, as still proceeding operation, as long as with finger blade 1 is chosen escape 10, just can achieve the goal.

Above-mentioned described electric knife mainly is to be applicable to face and the little deep operation of surgical field of view, and be used for common surgical procedures or surgical field of view big, the electric knife of performing the operation in hemorrhage more shallow deep, volume is bigger, its structure is seen Figure 10, its cutter hub 7 can serve as the handle of a knife of holding, also there is illumination channel its cutter hub 7 inside and attracts passage, blade 1 also adopts the bearing pin connected mode with knife bar, 1 one of cutter hub 7 top cutters also are provided with escape, be that blade 1 also can turn down into escape, because of attracting caliber bigger, on cutter hub 7, have the extraneous control hole 11 that communicates with its inner attraction passage 8, the operation teacher as long as block control hole with finger, just can regulate suction as required when attracting.

Accompanying drawing has been described embodiment of the present utility model:

Fig. 1 is this utility model direct rod shape electric knife sketch map,

Fig. 4 is this utility model knife bar 7 vertical curve shape electric knife sketch maps,

Fig. 5 is the electric knife sketch map of knife bar 7 shown in Figure 1, handle of a knife 5 inner band illumination channel, attraction passage,

Fig. 6, the 7th, knife bar 7, handle of a knife 5 section profiles among Fig. 5,

Fig. 8 is that this utility model blade 1 is connected the electric knife sketch map with cutter hub 3 bearing pins,

Fig. 9 is that the blade 1 of electric knife shown in Figure 8 folds into escape 10 sketch maps,

Figure 10 attracts passage 8 to be provided with the partial sectional view of control hole in electric knife of the present utility model, the knife bar 7.

Among the figure, 1. blade, 2. insulating barrier, 3. knife bar, 4. clamping nut, 5. handle of a knife, 6. bearing pin, 7. cutter hub 8. attracts passage, 9. illumination channel, 10. escape, 11. control holes.

In the above-mentioned part of this utility model, cutter hub 3, handle of a knife 5, clamping nut 4 are all made of insulant, in case the leak-stopping electricity, metalwork adopts the stainless steel material manufacturing, is equipped with optical fibers in the illumination channel.

In the above-mentioned electric knife of this utility model, not with illumination channel with attract the electric knife of passage because simple in structure, cost is low, be specially adapted to the infirmary of basic unit of economic condition difference, then suitable each specialist hospital configuration of the electric knife of band light source, attraction passage, through clinical verification, they are except that the function that possesses existing known electric knife, also, also can reduce the assistant in the operation applicable to operations such as skin, eye, ear,nose ﹠ throat, oral cavities, less demanding to the operating room lighting condition simultaneously, its easy operating, operation efficient height, effective, be worth promoting the use of in vast hospital.
