Abstract
It is that to melt cutter be coaxial cylindrical to many slot electromagnetic that many slot electromagnetic of disclosure of the invention melt cutter, and the inside and outside layer melting cutter is metallic conductor, fills dielectric between inside and outside layer metallic conductor, and outer layer metal conductor is equidistant offers at least 2 gaps radially.Invention can burn the pre-tangent plane of liver by single multiple spot electromagnetic wave, disposably sets up a complete hemostasis face, thus shortens operating time and significantly reduce operative hemorrhage.
Description
Technical field
Invention relates to a kind of medical apparatus and instruments, particularly relates to a kind of many slot electromagnetic and melts cutter.
Background technology
Scientific cirle outside, hepatotomy is considered highly difficult, and a high risk operation, the requirement to operator is the highest.And existing various hepatotomy equipment, all there is the mute time in various degree slow, the various complexity of operative process, the hemorrhage shortcomings such as many.Existing various RF/Microwave liver cutting equipment all uses single-point repeatedly to burn liver thus sets up tourniquet, and its process is slowly complicated and volume of leaving is hemorrhage.
Summary of the invention
Invention aims to provide a kind of many slot electromagnetic and melts cutter, uses single multiple spot electromagnetic wave to burn the pre-tangent plane of liver, disposably sets up a complete hemostasis face, thus shorten operating time and significantly reduce operative hemorrhage.
For reaching above-mentioned purpose, the technical scheme that invention uses is as follows:
It is coaxial cylindrical that many slot electromagnetic of disclosure of the invention melt cutter, and the inside and outside layer melting cutter is metallic conductor, fills dielectric between inside and outside layer metallic conductor, and described outer layer metal conductor is equidistant offers at least 2 gaps radially.
Invention is in use, encouraged by adaptive electromagnetic signal, its apertured outer layer can form multiple spot electromagnetic radiation, the axial dimension of every section of outer layer can be suitable with operation wavelength, add the working size melting cutter, the needs of longer surgical wound can be met, can disposably burn whole wound thus set up tourniquet.
Preferably, described gap number is the integer more than or equal to 2, and the width in each gap is incremented by the other end successively from the one end melting cutter.
Preferably, described dielectric is vinyl chloride.
Preferably, the inside and outside layer metallic conductor end melting cutter described in is connected and axially extending formation taper.
Many slot electromagnetic of disclosure of the invention melt cutter, the pre-tangent plane of liver can be burnt by single multiple spot electromagnetic wave, disposably set up a complete hemostasis face, thus shorten operating time and significantly reduce operative hemorrhage, disposably solve the problems such as the most hemorrhage and trivial operations, the liver process simplification of danger by complexity, it is made to become safety, easy, fast, in surgery of liver, there is great practical value, great Academic Influence and economic benefit will be produced.

Detailed description of the invention
In order to make the purpose of invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing, invention is further elaborated.
As shown in Figure 1, it is coaxial cylindrical that many slot electromagnetic of disclosure of the invention melt cutter, including outer layer metal conductor 1 and inner layer metal conductor 2, the external diameter of outer layer metal conductor 1 is 1.8mm, the external diameter of inner layer metal conductor 2 is 0.9mm, , dielectric 4 is filled between outer layer metal conductor 1 and inner layer metal conductor 2, dielectric 4 is vinyl chloride, outer layer metal conductor 1 equidistantly leaves 4 gaps radially, the width in 4 gaps from front end to end, be followed successively by 1mm, 1.3mm, 3.38mm, 6.59mm, the axial dimension of the outer layer metal conductor 1 between two adjacent slits is 25mm, the axial dimension of the outer layer metal conductor 1 at two ends is respectively 25mm；Inner layer metal conductor 2 is connected with outer layer metal conductor 1 end and axially extending formation taper.
As shown in Figure 2 and Figure 3, the angle of radiation of invention is good, and energy is concentrated, its reflection loss S11=-12.85dB.
As shown in Figure 4, when invention is placed in liver heating, the radius about 15mm of center 80 degree celsius temperature, it is possible to disposably set up a complete hemostasis face.
Certainly; invention also can have other various embodiments; in the case of without departing substantially from spirit and essence thereof, those of ordinary skill in the art can make various corresponding change and deformation according to invention, but these change accordingly and deformation all should belong to the scope of the claims appended by invention.
