The utility model discloses an utilize and improve bottom electrode surface characteristic, make smooth plane with the upper surface of bottom electrode, it is better with the tissue contact after the electrode centre gripping tissue about guaranteeing, the more smooth and easy electrode of passing through of electric current is organized with being cut, has fully promoted the ability and the cutting tissue speed that this electrode tip cut different grade type tissue.
Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to easily cut coagulated high frequency electrode tip.
Background
Electrosurgical devices have been standard in hospitals and various electrode heads have been developed for different surgical procedures. Among the electrosurgical apparatuses, bipolar electrosurgical instruments are widely used, and the principle of the bipolar electrosurgical instruments is that the positive electrode and the negative electrode of the electrosurgical instruments are integrated into the same medical instrument.
Most bipolar electrosurgical devices currently on the market share some common problems: the upper electrode and the lower electrode are not in complete contact with tissues, so that certain types of tissues are not completely cut or even difficult to cut, and the tissue cutting speed is low, so that the operation time of a doctor is prolonged, and the operation efficiency is reduced.
While another ultrasonic blade that uses more has some problems: the cutting head is easy to break when touching hard objects, the cutting speed is slow, the cutting head can not be used as a separating clamp, and blood can not be coagulated when liver tissues are cut.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, an object of the utility model is to provide an it is better with the tissue contact after making the upper and lower electrode centre gripping tissue, the more smooth and easy electrode that passes through of electric current with by the cutting tissue, the ability that fully promotes this electrode tip cutting different grade type tissue and the plane contact high frequency electrode tip of cutting tissue speed.
In order to achieve the technical purpose, the utility model adopts the following technical scheme: the plane contact type high-frequency electrode tip comprises an upper electrode and a lower electrode, wherein the upper surface of the lower electrode is a smooth plane, and the smooth plane forms a lower electrode cutter face; one side of the upper electrode, which faces the lower electrode, is provided with a cutting edge with a V-shaped section, the tip of the cutting edge extends to form an upper electrode knife face, and when the upper electrode and the lower electrode are closed, the lower electrode knife face is in contact with the upper electrode knife face.
Preferably, the width of the lower electrode gradually increases from the head end to the tail end.
Due to the adoption of the technical scheme, the utility model discloses following beneficial effect has at least: the surface characteristics of the improved lower electrode are utilized, the upper surface of the lower electrode is made into a smooth plane, so that the upper electrode and the lower electrode are in better contact with tissues after clamping the tissues, the current can more smoothly pass through the electrodes and the tissues to be cut, and the capability of the electrode tip for cutting different types of tissues and the tissue cutting speed are fully improved. The electrode has enough strength, is difficult to break, has a cutting speed higher than that of an ultrasonic knife, can be used as a separating forceps, and can be used for cutting and coagulating liver tissues.
Drawings
The drawings are only intended to illustrate and explain the present invention and do not limit the scope of the invention. Wherein:
fig. 1 is a schematic view of the state of the upper electrode and the lower electrode when the upper electrode and the lower electrode are opened according to the embodiment of the present invention;
fig. 2 is a schematic diagram of a state in which the upper electrode and the lower electrode are closed according to the embodiment of the present invention.
In the figure: 1-an upper electrode; 11-cutting edge; 12-upper electrode blade face; 2-a lower electrode; 21-lower electrode rake face.
Detailed Description
The invention is further explained below with reference to the drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention have been described by way of illustration only. Needless to say, a person skilled in the art will recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
Examples
As shown in fig. 1 and 2, the plane contact type high-frequency electrode head comprises an upper electrode 1 and a lower electrode 2, wherein the upper surface of the lower electrode 2 is a smooth plane which forms a lower electrode knife face 21; one side of the upper electrode 1 facing the lower electrode 2 is provided with a cutting edge 11 with a V-shaped section, the tip of the cutting edge 11 extends to form an upper electrode knife face 12, and referring to fig. 2, when the upper electrode 1 and the lower electrode 2 are closed, the lower electrode knife face 21 is in contact with the upper electrode knife face 12. Through utilizing and improving 2 surface characteristics of bottom electrode, make smooth plane with the upper surface of bottom electrode 2, guarantee that the bottom electrode centre gripping tissue back is better with the tissue contact, the more smooth electrode of passing through of electric current is organized with being cut, fully promotes the ability and the cutting tissue speed that this electrode tip cut different grade type tissue.
In this embodiment, the width of the lower electrode 2 from the head end to the tail end is gradually increased, so that the operation is more convenient and the structural strength is higher.
The working principle of the utility model is as follows: the upper electrode 1 and the lower electrode 2 are closed to clamp tissues, the functional button is excited to enable the high-frequency power supply generator to provide current, the current passes through the upper electrode, the tissues and the lower electrode, the tissues are cut off by the heat effect generated when the current passes through metal, and meanwhile, the tissues are coagulated by blood on two sides of the electrodes to stop bleeding on two sides of a cut.
Compared with an ultrasonic knife, the electrode has enough strength, is difficult to break, has a cutting speed higher than that of the ultrasonic knife, can be used as a separating clamp, and can be used for cutting and coagulating liver tissues.
The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
