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 cutting speed is slow, the coagulation effect on the cut tissue is poor, and the tissue and tissue fluid are easy to adhere. The slow cutting speed can increase the operation time of a doctor and reduce the operation efficiency; poor coagulation of the dissected tissue can result in the tissue becoming stuck with blood or secondary bleeding; the easily adherent tissue can greatly reduce the working performance of the electrode tip and often requires removal for cleaning during surgery.
While another ultrasonic blade that uses more has some problems: the cutter head is easy to break when touching hard objects. The cutting speed is slow, the cutting forceps can not be used as a separating forceps, and blood can not be coagulated when the liver tissue is cut.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, an object of the utility model is to provide a do benefit to and promote cutting tissue speed, blood coagulation effect and the insulating anti-adhesion embedded high frequency electrode tip of the not adhesion performance of tissue and tissue liquid.
In order to achieve the technical purpose, the utility model adopts the following technical scheme: the insulating anti-adhesion embedded high-frequency electrode tip comprises an upper electrode and a lower electrode, wherein a circular groove is concavely arranged on the upper surface of the lower electrode; and a cutting edge capable of being embedded into the circular groove is formed on one side of the upper electrode facing the lower electrode, guide surfaces matched with the groove walls of the circular groove are formed on two sides of the cutting edge respectively, and insulating anti-sticking strips are embedded on the guide surfaces respectively.
As a preferred technical scheme, the insulating anti-adhesion strips are formed on two sides of the cutting edge of the upper electrode in an injection molding mode.
Due to the adoption of the technical scheme, the utility model discloses following beneficial effect has at least: when the upper electrode and the lower electrode are closed, the upper electrode is guided under the action of the guide surfaces on the two sides of the cutting edge and is embedded into the circular groove of the lower electrode, the insulating anti-sticking strips are embedded on the two sides of the cutting edge, so that the cutting edge of the upper electrode, the insulating anti-sticking strips and the wall of the circular groove of the lower electrode are ensured to be in good contact, and the upper electrode, the insulating anti-sticking strips and the lower electrode are ensured to be in good contact with tissues when clamping tissue bundles, so that the tissue cutting speed and the blood coagulation effect of the electrode tip are improved, and the electrode tip is prevented from being adhered with the tissues and tissue fluid simultaneously, thereby improving the working performance of the electrode tip.

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 insulation anti-adhesion embedded high-frequency electrode head comprises an upper electrode 1 and a lower electrode 2, wherein a circular groove 21 is concavely arranged on the upper surface of the lower electrode 2; one side of the upper electrode 1 facing the lower electrode 2 is provided with a cutting edge 11 which can be embedded into the circular groove 21, two sides of the cutting edge 11 are respectively provided with a guide surface 12 which is matched with the groove wall of the circular groove 21, and the guide surfaces 12 are respectively embedded with an insulating anti-sticking strip 3. The best integrative injection moulding of insulating anti-sticking strip 3 in the blade both sides of upper electrode 1 can effectively prevent the problem that drops of insulating anti-sticking strip, and job stabilization, simple pleasing to the eye, the clean maintenance of the postoperative of being convenient for moreover.
Referring to fig. 2, when the upper electrode 1 and the lower electrode 2 are closed, the upper electrode 1 is guided and embedded into the circular groove 21 of the lower electrode 2 under the action of the guide surfaces 12 on the two sides of the cutting edge, so that the cutting edge 11 of the upper electrode, the insulating anti-sticking strips 3 and the circular groove 21 of the lower electrode are ensured to be in good contact, and when a tissue bundle is clamped, the upper electrode 1, the insulating anti-sticking strips 3 and the lower electrode 2 are ensured to be in good contact with tissues, so that the tissue cutting speed and the blood coagulation effect of the electrode tip are improved, and meanwhile, the electrode tip is prevented from being stuck with tissues and tissue fluid, so that the working performance of the electrode tip is improved, the problem of cleaning the electrode tip in.
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.
