Example 1
TABLE 1. example 1 Nanoalloy physical Properties
The inner surface of the forceps tip 3 is made of a conductive and heat-conductive nano alloy material, for example, the nano alloy material is silver-based alloy or nano reinforced copper alloy. The nano alloy is compounded and processed by high-quality electric and heat conducting metal, and meanwhile, in order to ensure the excellent mechanical property of the material, a large number of nano-scale strengthening particles (as shown in figure 7) are uniformly distributed in a material matrix, so that the nano alloy plays a strong role in hindering the sliding of a grain boundary and can obviously improve the mechanical strength of the alloy. Meanwhile, the alloy structure is fiberized through deformation processing such as hot extrusion and cold drawing, the number of transverse grain boundaries is reduced, and grain boundary slippage is also significantly impaired. Therefore, the nano alloy has high strength performance, and the performance is stable and does not generate attenuation at high temperature. The specific properties of the nano alloy material prepared by adopting the deformation processing auxiliary device in the preparation of the nano alloy material are shown in table 1.
The nano alloy forceps made of the material realizes stable work for a super long time and does not adhere to tissues through optimized combination by various processes such as vacuum electromagnetic induction melting, forging and pressing molding, vacuum coating and the like; the touch feeling can be clearly transmitted due to the hyperfine rebound force; the requirement of ultramicro kneading force is suitable for the doctor to operate for a long time without fatigue.
As shown in the figure, thermal imaging tests of the telescopic forceps show that the temperature is mainly concentrated on the electrocoagulation tissue, and the temperature of the peripheral tissue and the forceps body is controlled below 70 ℃.
In addition, since the nano alloy material has excellent electrical and thermal conductivity, heat transfer and energy exchange inside and on the surface thereof are extremely active. The high thermal conductivity in the material can quickly diffuse and transfer the discharge heat on the surface, so as to prevent the heat from gathering and further avoid the adhesion of tissues; meanwhile, the surface of the nano alloy material can rapidly decompose and fall off adhered foreign body tissues due to efficient energy exchange, so that the nano alloy forceps can self-clean the surface even under the condition of not carrying out external auxiliary wiping, and the tip part surface of the forceps is more luminous and sparkling as before in the use process.
Comparative example 1
The specific properties of the nano alloy material prepared by the method of the present invention are shown in table 2, which is the same as example 1 except that no deformation processing auxiliary device is used.
TABLE 2 physical Properties of the nanoalloys of comparative example 1
As can be seen from the data in tables 1 and 2, the nano alloy of example 1 has better physical properties. The nano alloy material prepared by the deformation processing auxiliary device has more excellent performance, and especially has higher electric conductivity and thermal conductivity.
The installation mode, the connection mode or the arrangement mode of the telescopic forceps are common mechanical modes, and the telescopic forceps can be implemented as long as the beneficial effects of the telescopic forceps are achieved.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
