Abstract
The utility model relates to a nonstick bipolar electric coagulation forceps for medical use, comprising a bivalve forceps handle and an electrode base. The tail ends of the bivalve forceps handle are respectively connected to the electrode base which is provided with a high frequency input plug. The external surface of the bivalve forceps handle is provided with an insulating layer. The material of the forceps tip is an alloy combining one or a plurality of metallic elements and a carbon element or is a combination of one or a plurality of metal materials and carbon materials. In the forceps tip material, the carbon content is no less than 20%. The processed molding of the forceps tip materials can be stamping, waterpower cutting, electrical spark processing, plasma cutting or molding process. The forceps tip material and the forceps handle are combined through mechanical method or colloid bonding. The surface of the forceps tip is coated with a biocompatible metal layer. Adopting appropriate forceps tip material, the nonstick bipolar electric coagulation forceps is advantageous in that the forming of adhesion and crust can be prevented due to the physical properties of the forceps tip material.
Description
Technical field:
Belong to medical instruments field, relate to a kind of medical non-stick bipolar electric coagulation forceps that in surgical operation, uses.
Background technology:
Bipolar coagulation forceps is important surgical operating instrument, is mainly used in electric coagulation hemostasis is carried out in the part, petechia.Bipolar coagulation forceps generally includes tweezer body, tweezer point, electrode tip holder, and the rear end of electrode tip holder connects power supply.Its operation principle is to use fully and the isolated high frequency electric source in ground, its two tips at bipolar coagulation forceps are discharged, thereby the tissue between the electric coagulation forceps is produced heat effect, local temperature is raise, tissue degeneratiaon, necrosis, drying, gasification, carbonization progressively appear, reach hemostasis and separate, thereby the protein in the solidificating blood reaches haemostatic effect.Not only anthemorrhagic speed is fast for this hemostasis mode, and haemostatic effect is good, and damages little.But bipolar coagulation forceps in use, easily in the most advanced and sophisticated formative tissue adhesion of two tweezers, form eschar, produce the insulation effect, electric coagulation hemostasis can not be proceeded, need clean the tweezer end repeatedly, especially under the untimely situation of hemorrhage removing, eschar forms just even more serious, removes relatively difficulty of carbonization piece from the tweezer point.So, operation process not only inadequately accurately but also more time-consuming even causes hemorrhage blood vessel electricity to coagulate not enough or electricity coagulates excessively.This not only has influence on the accurate hemostasis in the operation and the cleaning of surgical field of view, and has had a strong impact on the haemostatic effect of bipolar coagulation, has reduced the work efficiency and the accuracy of operation.
Bipolar coagulation forceps in the market comprises disposable bipolar coagulation forceps, reusable bipolar coagulation forceps and the bipolar coagulation forceps that cannot not be called stickingly, all has the adhesion problems of tweezers and tissue in the operation process.Have technology to solve adhesion problems, but water filling can bring new problem again in the operation process with water-filling method.
Description of drawings:
Accompanying drawing is that structural representation cuts open in office of the present utility model.
Among the figure: 1, tweezer body, 2, the tweezer point, 3, tweezer point coating, 4, tweezer body insulating coating or insulation sleeve, 5, electrode tip holder.
This sketch map only is used for illustrating the ingredient of tweezers, and the shape of actual tweezers is not limited to this figure, the tweezer body portion can according to practical operation conveniently be designed to shape arbitrarily, can be straight, crooked, arcual or the like shape.
Summary of the invention:
Technical problem to be solved in the utility model is to provide a kind of and can prevent the most advanced and sophisticated medical non-stick bipolar electric coagulation forceps that forms eschar of bipolar coagulation forceps when electric coagulation hemostasis.
This medical non-stick bipolar electric coagulation forceps includes bivalve tweezer body and electrode tip holder, and the tail end of bivalve tweezer body links to each other with electrode tip holder respectively, and electrode tip holder is provided with the high frequency input plug, and the external table of bivalve tweezer is provided with insulating barrier.It is characterized in that tweezer point material uses by the alloy of one or more metallic elements and carbon or by the combining of one or more metal materials and carbon material, metal material can be one or more in gold, silver, titanium, the rustless steel.In tweezer point material, carbon content is no less than 20%, and the cross-sectional sizes of tweezer point can have different sizes, under most of situation less than 1 millimeter * 1 millimeter.The length of tweezer nose part is proper with 35 millimeter, also can increase or reduce.The machine-shaping process of tweezer point material can be punching press, waterpower cutting, spark machined, plasma cutting or molding process.Tweezer point material and tweezer body combine by mechanical method or the bonding method of colloid.Tweezer point surface is coated with the biocompatible metal layer, and metal level is by one or more are formed in gold, silver, platinum, the titanium, and thickness is below 0.2 millimeter.
This utility model is owing to use suitable tweezer point material, and its physical property can suppress to produce the formation reason of adhesion and eschar, thereby can prevent the generation of eschar, the effect that cannot not reach stickingly.
Specific implementation method:
As shown in Figure 1, this non-stick bipolar electric coagulation forceps comprises tweezer body, tweezer point, electrode tip holder, links to each other with power supply when the rear end of electrode tip holder is used to use.The tweezer nose part can as in the boring of the joint of tweezer body and tweezer point, connect tweezer point and tweezer bulk phase, but will guarantee good electrical contact between tweezer body and the tweezer point simultaneously by the method for machinery.Also can make the tweezer body is a foil in the extension of tweezer point, and sheet thickness is usually less than 1 millimeter.With tweezer point material and thin slice is glued together or electricity consumption is welded together.Tweezer point material is coated with metal level, to guarantee good electrical conductivity and biocompatibility.
