Description

{Surgical Electrodes with Multi-functional}

The present invention relates to a multi-functional surgical electrode capable of performing cutting, coagulation, and suction functions in a single device.

A surgical electrode is a medical device, also called a Bovie knife or Bovie, that generates a specific current with a desired wavelength and frequency through a current generator, and locally transmits it to human tissue through the electrode tip to burn the tissue (affected area) with a kind of heat energy, thereby stopping bleeding or cutting. This Bovie knife is used when performing surgery in a hospital.

At this time, the high-frequency current of the surgical electrode can be directly focused only on the tissue to be incised or coagulated, thereby minimizing damage to surrounding tissue during surgery.

Meanwhile, surgical electrodes (Bovi) are configured with cutting (cutting), coagulation (coagulation), and suction (suction) functions, or even if they are configured with a combination of functions, they only have cutting (cutting) function + coagulation (coagulation) function or coagulation (coagulation) function + suction (suction). Therefore, surgical electrodes suitable for each purpose must be replaced and used during the surgical process, which causes inconvenience due to repeated replacement and delay in surgical time, which causes problems with patient stability.

In addition, conventional surgical electrodes have the problem that the manufacturing cost increases because each surgical electrode must be manufactured separately, and the efficiency of storage space and management efficiency are low because multiple surgical electrodes must be stored and managed separately.

In addition, conventional surgical electrodes can affect the quality of surgery when cutting and coagulating using the electrode tip due to foreign substances adhering to the electrode tip during the surgical process, and additional steps (removal using sandpaper) may be required to remove the substances adhering to the electrode tip from the electrode tip, which can cause problems such as delaying the surgical time.

Hereinafter, a composite functional surgical electrode according to a preferred embodiment of the present invention will be described with reference to the attached drawings 1 to 4.

The multi-functional surgical electrode is designed to perform cutting, coagulation, and suction functions in a single surgical electrode. Accordingly, the present invention can improve the convenience of the user (doctor) and the quality of the surgery, and can shorten the surgery time.

The multi-function surgical electrode may include a housing (100), a suction tube (200), an electrode tip (300), and a button (400), as illustrated in FIG. 1.

The housing (100) constitutes the exterior of a multi-functional surgical electrode and may be formed of a tube that forms a hollow internal space with both sides perforated.

The housing (100) may be made of an insulator, and the front end of the housing (100) may be formed to slope downwards as it approaches the end of the housing (100) to facilitate gripping.

In addition, the housing (100) may include a PCB (110). The PCB (110) serves to control the high-frequency current supply of the electrode tip (300), and various electronic components for supplying current may be mounted on the PCB (110).

At this time, the PCB (110) may include a first element (111) that forms a high-frequency current for cutting, a second element (112) that forms a high-frequency current for coagulation, and may include a power cable (113) that can receive external power. At this time, the first element (111) and the second element (112) may each include a switch (114) for a contact point.

Meanwhile, the housing (100) can form a hole (120) that can expose a switch (114) of the PCB (110). A button (400) that allows a user to contact the switch (114) to the element (111, 112) can be positioned in the hole (120).

The suction tube (200) forms a path for sucking foreign substances or blood generated during surgery using a surgical electrode, and is provided in the internal space of the housing (100).

The suction tube (200) serves to discharge foreign substances or blood generated from the surgical site by the power of a suction device (not shown) that generates suction force, and can be positioned in the length direction of the housing (100).

At this time, one side of the suction tube (200) forms an inlet (210) through which foreign substances or blood are introduced into the path of the suction tube (200), and the other side of the suction tube (200) forms an outlet (220) through which the foreign substances or blood are discharged.

Meanwhile, the suction tube (200) may include a tube tube (230), a metal tube (240), and a connector (250), as shown in FIG. 4.

The tube (230) is a tube that flows foreign substances or blood, etc., toward the suction device, and in particular, serves as a connecting means for connection to the suction device.

In addition, the tube tube (230) is made of a soft insulating material so that the user can freely move the surgical electrode. In addition, the tube tube (230) can be made transparent or translucent so that the flow of foreign substances or blood, etc. can be visually confirmed. In addition, the length of the tube tube (230) is not limited, but it is preferable that the tube tube (230) is formed longer than the length of the housing (100) so that it is exposed from the housing (100).

The metal tube (240) forms an inlet (210) for introducing foreign substances or blood generated during surgery, and can play a role in transmitting high-frequency current generated from the PCB (110) to the electrode tip (300). At this time, a current cable (260) for conducting high-frequency current to the metal tube (240) can be installed between the PCB (110) and the metal tube (240).

Meanwhile, the metal tube (240) is made of a metal conductor. At this time, the metal tube (240) is made of a tube body with both sides penetrated, and can be fixed to the end of the tube tube (230) through a fitting connection. To this end, the inner diameter of the tube tube (230) and the outer diameter of the end of the metal tube (240) can be made to a size that can be forcibly fitted to each other. The length of the metal tube (240) is also not limited, but it is preferable that it be a length that can protrude through one side of the housing (100) while being fitted to the tube tube (230).

The connector (250) serves to connect the tube tube (230) to the extension tube (not shown) of the suction device. The extension tube is connected to the suction device and is configured to be connected to the tube tube (230) of the surgical electrode, and may be made of the same material as the tube tube (230). It is preferable that the extension tube be formed to have a relatively long length compared to the tube tube (230) so that there is no limitation on the distance between the surgical electrode and the suction device.

The connector (250) may be made of resin, and protrusions may be formed on both ends of the connector (250) to increase the bonding strength with the soft tube (230) and the extension tube.

The electrode tip (300) receives high-frequency current through the control of the PCB (110) and serves to cut a portion of human tissue or coagulate a portion of the cut human tissue.

The electrode tip (300) is formed so as to be able to receive current through the PCB (110), and may be formed in the suction tube (200) as shown in FIGS. 1 to 4. To be precise, the electrode tip (300) is formed in the metal tube (240) constituting the suction tube (200), and is formed so as to protrude from the tip of the metal tube (240). At this time, it is understandable that the electrode tip (300) can receive current through the current cable (260) formed between the metal tube (240) and the PCB (110).

In addition, the electrode tip (300) is formed to protrude from the inlet (210) of the metal tube (240), and the thickness of the electrode tip (300) is formed to be smaller than the inner diameter of the inlet (210). Accordingly, even if the electrode tip (300) is formed in the inlet (210), the inlet (210) is not blocked.

At this time, the electrode tip (300) may be formed in a plate shape that crosses the inlet (210) vertically, and thus, when the surgical electrode is in operation, foreign substances or blood, etc. may be introduced into the metal tube (240) through the inlet (210) on the left and right sides of the electrode tip (300) based on the electrode tip (300).

At this time, the electrode tip (300) can be fixed to the inner surface of the inlet (210) of the metal pipe (240) through welding.

In addition, the frontmost end face of the electrode tip (300) can be formed to be rounded convexly toward the front. This allows the user to perform the surgical operation on the patient's affected area more stably.

Meanwhile, the electrode tip (300) can form a coating layer (310) to prevent foreign substances from sticking (adhesion) during surgery and to easily remove foreign substances even if they do stick.

At this time, the coating layer (310) can be formed through Teflon coating, and it is preferable that the color of the Teflon coating layer (310) is black. At this time, the reason for forming the black Teflon coating layer (310) is to prevent the light for endoscopic surgery from being reflected on the metal electrode tip (300) during endoscopic surgery, thereby improving the quality of the surgery.

The button (400) is formed to contact the first element (111) and the second element (112) of the PCB (110), and can be formed at positions corresponding to the first element (111) and the second element (112) of the PCB (110), respectively.

The button (400) is formed so as to be able to press the switch (114) formed on the first element (111) and the second element (112) while moving between the first element (111) and the second element (112) toward the first element (111) or the second element (112), that is, in the forward and backward direction of the housing (100).

At this time, the button (400) is installed in the hole (120) of the housing (100) for the user's operation, and can shield the switch (114) exposed through the hole (120).

Hereinafter, the operation of the composite functional surgical electrode having the above-described configuration will be described.

A suction device is provided in the operating room, and the user connects the extension tube of the suction device to the connector (250) of the surgical electrode.

Afterwards, power is supplied to the surgical electrode by connecting the plug of the power cable (113) to the power supply of the operating room.

Thereafter, the user operates the suction device to generate suction force in the suction tube (200) and brings the electrode tip (300) to the patient's affected area.

Thereafter, the user presses one side of the button (400) to apply power to the first element (111) to cause the electrode tip (300) to generate high-frequency current for cutting, or presses the other side of the button (400) to apply power to the second element (112) to cause the electrode tip (300) to generate high-frequency current for coagulation, thereby performing the surgery.

At this time, since a suction force is continuously generated in the flow path of the suction tube (200), foreign substances and blood, etc. generated during cutting or coagulation through the electrode tip (300) are sucked in through the inlet (210) of the metal tube (240) formed on the left and right sides of the electrode tip (300).

Afterwards, the user can perform surgery using a surgical electrode by performing a series of processes as described above.

As described so far, the multi-functional surgical electrode according to the present invention can perform incision, coagulation, and suction functions in a single device, thereby eliminating the need to replace devices to perform each function during surgery, thereby increasing the convenience of the user's surgery, shortening the surgery time, and improving the quality of the surgery.
