Description

Plasma tungsten knife

Technical field

The utility model is related to tungsten knife, more specifically to a kind of plasma tungsten knife.

Background technology

Existing frequently-used ablation hemostatic device, mainly uses high frequency electric transmission energy, but heat is uneven, and security Have much room for improvement.And cutter head is usually rectangle, because its structural relation, accumulate smaller with tissue contact surface, haemostatic effect is not good, also Easily cause tissue charring and adhesion.And existing cutter head typically all uses stainless steel, prolonged operationses can cause knife Sword rust, extremely influences surgical effect.

Utility model content

The technical problems to be solved in the utility model be there is provided it is a kind of can fly-cutting hemostasis, energy transmission it is stable by Heat is uniform and cutter head can keep sharp plasma tungsten knife.

The utility model solves the technical scheme that its technical problem used：A kind of plasma tungsten knife, including handle, institute Stating handle has hollow cavity, and inside cavity is provided with the first suction tube, and the handle front end is provided with lighting device；It is described Handle surfaces it is embedded be provided with TURP key, coagulation key and light switch, the TURP key, coagulation key and light switch respectively with The PC connecting plates connection of handle inner is arranged on, PC connecting plates are connected by the first wire with external power source, and PC connecting plates are set On the first suction tube top；The lighting device is connected by the second wire with light switch, and the second wire is connected with battery, institute State the first suction tube to connect by one end of metal connecting piece and knife bar, be provided with the second suction tube outside knife bar, knife bar it is another Outer one end is provided with cutter head, and the cutter head front end is semicircle or tip shape, and rear end is square, and three faces are put the first edge on a knife or a pair of scissors, the handle tail End is provided with handle tail.

By such scheme, the cutter head bending angle is straight, bending or is straight bending.

By such scheme, the cutter head is tungsten metal.

By such scheme, waterproof material is laid with outside the lighting device, lighting device is LED illumination, optical fibre illumination Or laser lighting.

By such scheme, the handle tail connection plasma transmitting main frame.

Implement plasma tungsten knife of the present utility model, have the advantages that：

1st, cutter head is unique semicircle, more meets structoure of the human body, accumulates bigger with tissue contact surface, and ablation, hemostasis are faster Speed, substantially increases procedure efficiency, and heat transfer is stable, and heat is more uniform, and tissue charring and adhesion is not resulted in art；

2nd, the cutter head heat of triangle focuses on tip, and cutting is sharper, and the design of three face blades is also very suitable for small model Enclose interior different directions reciprocating cutting, ablation and stop blooding, actuating length is short, operates more conveniently, safely, exclusive bending knife Head design, is adapted to the operative site of angle of bend；

3rd, it is made of high tungsten alloy material, the fusing point of its superelevation makes cutter head highly heat-resistant, and prolonged operationses can also be protected Hold keen edge incomparable, plasma technology provides and can also keep being melted under low temperature in art, cut, stop blooding, intraoperative hemorrhage Few, fire damage is small, safe, and post-operative recovery is fast.

Embodiment

In order to be more clearly understood to technical characteristic of the present utility model, purpose and effect, accompanying drawing is now compareed detailed Illustrate embodiment of the present utility model.

As Figure 1-5, plasma tungsten knife of the present utility model includes handle 1, the first suction tube 15 and the second suction tube 12。

Handle 1, which has, is provided with the first suction tube 15 and PC connecting plates 6, the first suction tube 15 in hollow cavity, cavity The top of PC connecting plates 6 is arranged on, the head of the first suction tube 15 is connected by metal connecting piece 10 with one end of knife bar 11, handle 1 afterbody is provided with handle tail 14.The connection plasma transmitting main frame of handle tail 14.What the surface of handle 1 was embedded in is provided with electricity Key 3, coagulation key 4 and light switch 5 are cut, TURP key 3, coagulation key 4 are connected with PC connecting plates 6 respectively with light switch 5.PC connections Plate 6 is connected by the first wire 7 with external power source.The second suction tube 12, the other end of knife bar 11 are provided with outside knife bar 11 It is connected with cutter head 13.The front end of cutter head 13 is semicircle, and rear end is square, and three faces are put the first edge on a knife or a pair of scissors, and front end may be alternatively provided as tip shape；Cutter head 13 can be with knife bar 11 on the same line, i.e., cutter head 13 is with knife bar 11 into straight, and cutter head 13 also can be angled with knife bar 11, I.e. cutter head 13 is in bending with knife bar 11, and the rear portion of cutter head 13 is set with the coupling part of knife bar 11 to be in line, before cutter head 13 The rear portion of portion and cutter head 13 is into bending, i.e. cutter head 13 and knife bar 11 into straight bending.Cutter head 13 uses tungsten metal material.

The front end of handle 1 is provided with lighting device 2, and lighting device 2 is connected by the second wire 8 with light switch 5, and second leads Line 8 is connected with battery 9.Waterproof material is laid with outside lighting device 2, lighting device 2 uses LED illumination, or uses optical fiber Illumination, can also use and LED illumination is used in laser lighting, this example.

In use, the first wire 7 is connected after plasma transmitting main frame, energy is transmitted by cutter head 13, makes the He of cutter head 13 Plasma thin layer is formed between tissue, layer intermediate ion transfers energy to tissue by electric field acceleration, (40 DEG C -70 at low temperature DEG C) ablation hemostasis is carried out to tissue.Exclusive semicircle cutter head, the distance that energy reaches blade is identical, and energy transmission is stable, heat Amount does not result in tissue adhesion, charing evenly, in art, to human body safety on the basis of surgical effect is ensured.Pass through behaviour The button made on handle 1 just can be with handoff functionality pattern.

Embodiment of the present utility model is described above in conjunction with accompanying drawing, but the utility model is not limited to The embodiment stated, above-mentioned embodiment be only it is schematical, rather than restricted, this area it is common Technical staff is not departing from the utility model objective and scope of the claimed protection situation under enlightenment of the present utility model Under, many forms can be also made, these are belonged within protection of the present utility model.
