Abstract
The utility model relates to a HF nano-diamond film operation knife, which comprises an operation knife body 1, the surface of the operation knife body 1 is provided with a deposited nano-diamond film 2 which contains a non-crystal carbon film with nano-diamond structure, the non-crystal carbon film has similar performance to a diamond film, therefore. Compared with the prior art, the utility model has the advantages of super-sharpness without adhering meat and blood.
Description
This utility model relates to medical apparatus and instruments, particularly relates to the used radioknife of a kind of surgical operation.
In the prior art, the used radioknife of surgical operation is made by rustless steel, can send unpleasant stink with muscle adhesion and under the electrical heating effect during use, surface and blade that burnt muscle is bonded at scalpel make the medical worker clean very trouble, bring many inconvenience to operation.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and proposes a kind of nano-diamond film radioknife of very sharp, sticking meat.
The purpose of this utility model can be by realizing by the following technical solutions:
Design and produce a kind of nano-diamond film radioknife, comprise scalpel body 1, in addition, there is the sedimentary nano-diamond film of one deck (Nana-DF) on scalpel body 1 surface.Because the Nana-DF film has very little surface energy and the affinity between the meat is little, so can obviously improve the performance of radioknife.
The drawing of accompanying drawing is described as follows:
Fig. 1 is this utility model nano-diamond film radioknife sketch map;
Fig. 2 is a nano-diamond film depositing system pie graph;
Fig. 3 is a nano-diamond film deposition schematic diagram.
Most preferred embodiment below in conjunction with accompanying drawing is described in further detail.
A kind of nano-diamond film radioknife as shown in Figure 1, comprises scalpel body 1, and in addition, there is the sedimentary nano-diamond film 2 of one deck on scalpel body 1 surface.Scalpel body 1 is formed from steel.
The thickness of described nano-diamond film 2 is 100 nanometers-1 micron, heat stability and electric conductivity that the nano-diamond film of boundary between this thickness is good.
Mainly contain carbon, a spot of hydrogen and a small amount of transiting group metal elements in the nano-diamond film, interatomic bonding mode is C-C, C-H, C-transiting group metal elements, and the bonding mode between the carbon atom mainly contains Sp
3Key and a spot of Sp
2Key.
The deposition of this nano-diamond film adopts radio frequency glow discharge plasma activated chemical vapour deposition (RF-PCVD) and the adulterated method of thermal evaporation.As Fig. 2, shown in Figure 3, after with vacuum pump 3 reative cell 4 being evacuated, gas source and control system 5 feed unstripped gas such as hydrogen, methane to reative cell 4, connect radio frequency plasma power supply 6 then, and the temperature of 8 pairs of reative cells 4 of monitoring system, air pressure etc. are monitored; With copper 7 is an electrode, and scalpel body 1 is another electrode, adds radio-frequency voltage and cause glow discharge between two parallel-plate electrodes, thereby make the working gas between the battery lead plate form high-temperature plasma, and last Nana-DF deposits to the scalpel body surface.Except that methane, butane, methanol, ethanol, acetylene or propane etc. also can be as the carbonaceous gas sources.The concentration of carbonaceous gas such as methane is at 0.5-8%.
Except that said method can be used for the Nana-DF thin film, also available ion beam depositing (IBM), ion beam assisted depositing (IBED), radio-frequency sputtering (RFS), magnetron sputtering (MS), direct current glow discharge plasma activated chemical vapour deposition (DC-PCVD), electron cyclotron plasma activated chemical vapour deposition (ECR-CVD), vacuum cathode arc deposited (VCAD), high-intensity currrent direct current arc method (HCDCA), laser plasma body chemical vapor phase growing (L-PCVD), laser arc deposition (LAD), methods such as organic solution electrolysis and polymer pyrolysis.
As everyone knows, diamond is an occurring in nature the hardest known material, has the best and extremely low advantage of coefficient of friction of thermal conductivity.Nano-diamond film is the amorphous carbon-film that contains the Nano diamond structure, and many character similar to diamond film are arranged, so, compared with prior art, the advantage that the utlity model has sharp, sticking meat and do not glue blood.
Described Nana-DF thin film can deposit on the scalpel of common steel equally, and the general surgery cutter that deposits the Nana-DF thin film cannot not have stickingly meat, sticking blood, sharper advantage.
