Specific embodiment

Illustrate specific embodiment of the present utility model below according to Fig. 1 to Fig. 2.The explanation is not that limitation is originally practical Novel specific embodiment, and it is one kind of the embodiments of the present invention.

As shown in Figures 1 and 2, cutting tool 100 is pierced according to a kind of operation of an embodiment of the utility model, it includes Have: a thorn cutting tool 11, the thorn cutting tool 11 have a cone-shaped sharp tip 111, which cuts human body group for piercing It knits；And a graphene layer 12, it is coated in the whole outer surface of the sharp tip 111 of the thorn cutting tool 11.

Graphene layer 12 has many excellent material properties, includes high mechanical strength, wearability and corrosion resistance.Cause This, graphene layer 12 is coated on the outer surface of the sharp tip 111 of thorn cutting tool 11, can achieve protection thorn cutting tool 11 The effect of sharp tip 111, to extend the service life for thorn cutting tool 100 of performing the operation.In addition, graphene layer 12 has good thermal conductivity And electric conductivity, therefore graphene layer 12 can also promote the electric conductivity and thermal conductivity of the sharp tip 111 of thorn cutting tool 11.Such as This thorn cutting tool 11 can discharge at very low power burns the various tissues of cutting, to obtain and keep sharp tip 111 good Sharpness.Simultaneously there is the sharp tip 111 of good sharpness can promptly cut skin and various soft tissues, effectively reduce Tissue necrosis realizes precisely cutting and burns and be greatly decreased operative hemorrhage, to improve the cutting for thorn cutting tool 100 of performing the operation Efficiency.

Specifically, referring to Fig. 1 and Fig. 2, this operation thorn cutting tool 100 is applied to the micro- of surgical operation medical treatment Invasive procedures electric knife.In the present embodiment, this thorn cutting tool 11 is an active thorn cutting tool, has an energization end 112, the energization End 112 is for being electrically connected a power supply unit (not being painted).And thorn cutting tool 11 sharp tip 111 and energization end 112 it Between, one insulating part 13 of installing is on thorn cutting tool 11.Specifically, this thorn cutting tool 11 must rely on power supply unit when in use There is provided electric current cuts the operation of tissue to carry out thorn.This electric current is sent to the sharp keen of thorn cutting tool 11 via energization end 112 End 111, and generate to discharge by sharp tip 111 and burn and be able to thorn and cut tissue.

In the present embodiment, thorn cutting tool 11 is as made by stainless steel, wolfram steel or other metal materials.It is so without being limited thereto, The other embodiments of the utility model are also possible to the electric knife that stops blooding.In addition, in the present embodiment, 12 system of graphene layer is only coated in Pierce the surface of the sharp tip 111 of cutting tool 11.And in other embodiments, in order to more improve operation thorn cutting tool 100 Cutting efficiency, so 12 system of graphene layer, which is coated in energization end 112 and extends, is coated in sharp tip 111.Therefore, power supply unit institute The electric current system of offer is directly sent to the graphene layer 12 on sharp tip 111 by the graphene layer 12 on energization end 112.Due to stone Black alkene layer 12 has excellent electric conductivity, therefore can promote the electric discharge cauterization effect of sharp tip 111, to improve thorn cutting of performing the operation The cutting efficiency of tool 100.

So without being limited thereto, active thorn the active of cutting tool is also possible to compressed gas, to assist this thorn cutting tool 11 to carry out Thorn cuts the operation of tissue.It is understood that thorn cutting tool 11 is also possible to a passive thorn cutting tool, this is passive to refer to not It needs to apply other external source conditions such as electric current on thorn cutting tool 11, only relies solely on medical staff and exerted a force by piercing cutting tool 11 The operation of tissue can be cut to carry out thorn.In the other embodiments of the utility model, this passive thorn cutting tool be can be Injection needle apparatus, surgical probe, file, osteotome or scalpel.

Referring to Fig. 1 and Fig. 2, specifically, the graphene layer 12 is with physical vaporous deposition (PVD) or chemical gas Phase sedimentation (CVD) is coated in the whole outer surface of the sharp tip 111 of thorn cutting tool 11, and the coating thickness of graphene layer 12 is situated between In 0.35nm between 200nm.In the present embodiment, it is imitated to reach optimal wearability and electric conductivity under cost viewpoint Fruit, the optimum thickness of this graphene layer 12 is between 60nm between 100nm.In addition, in other examples, in order to lower thorn The stress of combination interface between cutting tool 11 and graphene layer 12, in the sharp tip 111 and graphene layer 12 of thorn cutting tool 11 Between be provided with an intermediary layer (not being painted).This intermediary's series of strata is first coated in the whole appearance of the sharp tip 111 of thorn cutting tool 11 On face, then graphene layer 22 is coated on intermediary layer.And the thermal expansion coefficient of this intermediary layer is between the warm of thorn cutting tool 11 Between the coefficient of expansion and the thermal expansion coefficient of graphene layer 12.

Referring to Fig. 3 and Fig. 4, cutting tool 200 is pierced in a kind of operation of another embodiment according to the utility model, this Operation thorn cutting tool 200 is the surgery electric knife applied to surgical operation medical treatment.This operation thorn cutting tool 200 includes: one Cutting tool 21 is pierced, which has the sharp tip 211 of a blade-like, which cuts tissue for piercing；With And a graphene layer 22, it is coated in the sharp tip 211 of the thorn cutting tool 21.Specifically, this operation thorn cutting tool 200 with it is upper The discrepancy for stating operation thorn cutting tool 100 is mainly that the shape for piercing the sharp tip 211 of cutting tool 21 is to be different from thorn cutting The shape of the sharp tip 111 of tool 11.Specifically, 211 system of sharp tip of thorn cutting tool 21 is in blade-like, and pierce cutting tool 11 Sharp tip 111 is then in cone-shaped.Although the shape of sharp tip 211 is the shape for the sharp tip 111 being different from, sharp tip 211 and sharp tip 111 all have for piercing the sharp edge for cutting tissue.In other words, the utility model does not limit thorn cutting The outer shape of the sharp tip of tool, as long as sharp tip can be applied with being used to pierce the sharp edge for cutting tissue originally practical new In type.

By above structure, graphene layer is coated on the outer surface of the sharp tip of thorn cutting tool, can achieve protection Pierce the effect of the sharp tip of cutting tool.This graphene layer can prevent sharp tip because between bodily tissue or body fluid blood Contact wears away and leads to the problem of sharp tip rust.Therefore, graphene layer can effectively extend the use longevity of operation thorn cutting tool Life, to mitigate burden of the hospital in medical treatment cost.In addition, the graphene layer with thermal conductive resin and electric conductivity can also mention The electric conductivity and thermal conductivity for rising sharp tip, allow medical staff more rapidly to complete surgical medical operation.

It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art Understand, without departing from the spirit and scope defined by the claims, can many modifications may be made, variation or it is equivalent, but It falls within the protection scope of the utility model.
