Abstract
The invention discloses a multiple-surface operation electrotome tool bit. The front end of the tool bet is coated with an anti-sticking conductive perfluoro caprylic acid material; the middle of the tool bit exposed outside a tool shank is coated with an insulating high-temperature resistant perfluoro caprylic acid material; the upper edge and the lower edge of the front end of the tool bit are parallel with each other; the upper edge and a beveled edge form an angle of between 45 and 60 degrees; the intersection part of the edges is cambered; all the margins of the upper edge, the lower edge and the beveled edge are chamber angles; the length of the beveled edge is between 2 and 4 millimeters; and the length of the lower edge is between 2 and 3 millimeters. The beveled edge of the front end of the multiple-surface operation electrotome tool bit and a cutting plane just form surface-to-surface contact, thus the problems that the cutting depth in a tissue is hard to control and deep part important tissues of a cut surface are easy injure accidentally because of cutting on different planes in the cutting process; more importantly, the surface can play a role in separating passivity and scrapping. The surface on the lower edge of the front end of the tool bit can also cut the tissues on an electric coagulation lateral surface to form use functions of a plurality of surfaces.
Description
Technical field
The present invention relates to electrosurgical commonly used in a kind of medical operating, refer in particular to multi-side operation electric knife head.
Background technology
Electrosurgical is that the surgeon implements one of the medical apparatus and instruments of the most normal use of performing the operation.The operation technique doctor knows in the operation practice, whole electric knife and cutting planes formed the angle about about 45-60 degree when general patient held cutter during surgical operation, and traditional cutter head forms some face between cutter head and tissue or point when using and contacts with putting, will cut and organize the depth in the easy generation of when operation like this holds bad, very easy generation is not cut at grade and is accidentally injured the vital tissue in facet deep, as easily accidentally injuring blood vessel bile duct etc. when the skeleton operation.The traditional electrical jet blade is made with rustless steel, easily produces tissue and the cutter head eschar that sticks together especially in when cutting when electricity coagulates and pulls up in the lump with cutter and make the hemostasis failure; The traditional electrical jet blade when work full cutter head all be in electriferous state, and in fact except that the fraction of head end, the major part of cutter head does not need to conduct electricity, the chance of the tissue that the mistiming of working like this is out because of injures heightens; Tradition cutter head front end is also curved, and about 2 millimeters of the connection terminals spacing of arc, it is clumsy just to seem when carrying out the cutting of more exquisite fine tissue like this.Above reason makes the electric knife head that uses at present because of its shape and material, uses certain limitation.Develop improvement is arranged on a material, a plurality of available, the electrosurgical cutter head that operability, the suitability and safety all can improve during operation is necessary.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of multi-side operation electric knife head, also is that it is a kind of " a many-side people's cutter head ".Compare with the traditional electrical cutter head, the shape difference of this cutter head front end, front end has added non-adhesive material in addition, and the middle part has added insulant.Can form a plurality of function of use like this, two faces are arranged in the time of this usefulness face, this is with some time function a little, and the function of this point is meticulousr.In addition, the interpolation of two kinds of materials improves its operability and safety greatly.The surface area of this cutter head contact tissue is bigger, and electricity coagulates better effects if when performing an operation.
The technical problem to be solved in the present invention is realized by following scheme: multi-side operation electric knife head, make with stainless steel material, and it is characterized in that: the cutter head front end is coated with antiseized conduction perfluoro caprylic acid material; Be exposed to the outer part of handle of a knife in the middle of the cutter head and be coated with high-temperature insulation perfluoro caprylic acid material, cutter head front end top is with following parallel, and top and hypotenuse are 45-60 degree angle, each intersection area, limit is arc, the edge of top, bottom, hypotenuse is chamfering, the long 2-4 millimeter of hypotenuse, following length of side 2-3 millimeter.
The present invention also comprises following scheme: described hypotenuse end points is connected by arc with described top.
The invention has the advantages that:
1, the end of this multi-side operation electric knife head (top and hypotenuse intersection area) is curved, and this is easier to carry out cutting of some delicate tissues and coagulate.
2, cutter head front end hypotenuse and cutting planes form contacting of face and face just, the time reduced as far as possible in cutting like this and cut and organized the depth and hold bad, difficult generation resembles does not cut at grade and accidentally injures the problem of facet deep vital tissue, the more important thing is that this face can play passivity and separate and scrape.
3, this face of cutter head front end bottom can cut electricity and coagulates lateral tissue and can play passivity separation and scrape, and forms a plurality of function of use.
4, this multi-side operation electric knife head increases than the surface area of conventional knives head portion contact tissue, and electricity coagulates better effects if when doing picture hepatotomy and so on operation.
5, the cutter head front end all is coated with material antiseized, high temperature resistant, anticorrosion, conduction; Be exposed to the outer part of handle of a knife in the middle of the cutter head and be coated with insulation, high temperature resistant, antiseptical material, eschar and cutter head adhesion cause eschar to pull up in the lump together with cutter head when restrainting to have avoided conventional knives to condense at electricity, cause once more hemorrhage.The use of mid portion insulant makes electric knife, and the tissue that is out because of injures of mistiming and the risk of internal organs significantly reduce in working order.
Description of drawings
Below in conjunction with accompanying drawing for embodiment:
Fig. 1 is the front view of this multi-side operation electric knife head
Fig. 2 is the vertical view of Fig. 1
The specific embodiment
As shown in Figure 1, multi-side operation electric knife head is made with stainless steel material.Cutter head front end 1 is coated with antiseized conduction perfluoro caprylic acid material; Be exposed to the outer part 2 of handle of a knife in the middle of the cutter head and be coated with high-temperature insulation perfluoro caprylic acid material.Cutter head front end 1 top 3 is parallel with following 4, and top 3 is 55 degree angles with hypotenuse 5, and each intersection area, limit is arc.The edge of top 3, bottom 4, hypotenuse 5 is chamfering, 3 millimeters of hypotenuse 5 length, 2.5 millimeters of following 4 length.The end points of hypotenuse 5 is connected with top 3 arcs.
Claims (2)
