Description

Electrocautery that has both gas suction and gas jet mechanism

In the present invention, when the incision and closure of the affected area using the electrocauterization action, the suction means of the gas for sucking the foreign substances such as smoke, bleeding material and the injection means of the gas for blowing off the foreign substances together around the cauterization electrode and the suction, injection The present invention relates to an electropneumatic device in which an inflow and outflow structure is organically configured to enable effective cooperation between means.

Electrocautery is a kind of thermal energy that generates a specific current with a desired wavelength and frequency through a current generator and delivers it locally to human tissue through a probe or blade type cauterized electrode provided at the end of the hand tool. It is said to destroy tissue by.

Electrocautery is commonly used to remove or deform soft tissue parts. It is also used to join tissues or cut them in place of surgical knives or other sharp tools. The cauterized area is covered with granulation tissue due to coagulation necrosis, and it is very effective for ablation of organs that are easily bleeding due to easy hemostasis of small bleeding during surgery.

The intensity of the current applied to the cauterized electrode in the electrocauterizer is precisely controlled so that it only affects the tissue in a specific area. Electrocautery is used to melt or press on biological tissues by heat from surface contact current, rather than cutting with force, making it easier to work on soft tissues that are difficult to treat, bleeding is easier to control, and scar tissues are less formed during treatment. Can be. However, there is no bleeding when cutting tissue, and during the sticking process, the burning environment and the smoke that is bad for the human body emit a bad treatment environment.

The electrocauterizer disclosed in the following document (1) is provided with a gas injection means for removing bleeding from the affected area. At the end where the cauterization electrode is disposed, the nozzle is provided with a positive pressure gas, and the injection tube is configured to penetrate the inside of the electrode. The user can secure the field of view of the ablation while removing the bleeding with the gas injected from the nozzle.

Document (2) shows an electropneumatic device in which the suction means penetrating the inside of the fuselage, the suction port disposed under the cauterizing electrode, and the lighting means arranged on the cauterizing electrode are combined. The user can secure the field of view of the ablation while sucking the bleeding or the like through the suction port.

Literature (3) relates to a knife-shaped coupled lesion ablation system and method that is not directly related to electrocauterization, or electrocution in that an ablation probe, such as a small-acting probe, is placed in the inner region of the inlet for sucking foreign matter from the ablation section. The present invention proposes a bleeding inhalation means that can be effectively applied when a large area is excised.

The prior art documents introduced all employ only one of the intake and exhaust means of vacuum pressure (negative pressure) or compression pressure (positive pressure). That is, only one action of sucking or blowing smoke, bleeding, etc. generated at the ablation site can be performed. However, if only one of these actions is performed is often insufficient, medical assistants are needed to help the rest of the action. As a result, there is no significant difference from the conventional method in which the medical assistant should help each with a dedicated suction and injection device.

The reason why inhalation or injection alone is not an adequate adjuvant in electrocauterization is as follows. First of all, the bleeding generated during the melting and cutting process comes up on the surface while forming droplets from the inside of the cutting tissue, and the excessive suction means may provide a cause for worsening the bleeding or deforming the cut surface shape. Therefore, it is more effective at this time to make a small blow using a fine jetting action that allows the bleeding to remain under the cut tissue or to selectively push out only the blood that has already flowed out.

On the other hand, the smoke generated by the heat-pushing process, which rises and spreads as soon as it is produced on the outer surface of the skin tissue, causes a slight blow to spread the smoke further, and has no effect on removing the smoke from the indoor space. Does not reach. Therefore, in this case, the suction action of sucking the rising smoke is more effective.

As a result, in the cutting process, the spraying effect is effective to secure the field of view of the cutting surface, and the suction process of removing the smoke generated during the pressing process for the purpose of hemostasis is effective. Therefore, in order to realize a true one-man operating electronic sterilizer without the need for medical assistants, both the proper suction means and the discharge (injection) means need to be implemented integrally with the cauterizer to work with the cauterization electrode. Injection, each action should not interfere or adversely affect each other.

In general, when the suction means and the injection means are disposed adjacent to each other, the medium is not interfered with each other. For example, when the suction means to suck water and the spray means for flushing water are arranged close to each other, the flushed water does not play its role or the spray pressure is too strong to be inhaled at all. This phenomenon becomes more prominent in the operation of the suction and injection means for shooting and sucking a light medium such as air.

Therefore, a structure in which the suction means and the jet means using different media are arranged in one electrocauter, especially water that is selectively sucked only the gas such as smoke and is not interrupted by the suction flow as the gas is sucked. Electrocauterine is configured to selectively discharge the bleeding by spraying the laparoscopic surgery is selectively used. However, this method of shooting a large amount of water through the suction pressure is not effective for the treatment site exposed to the outside, such as skin because the water mixed with blood flows down in a large amount.

As a result, to solve this problem in electronic sterilizers dealing with treatment parts exposed to outside air, more precise analysis of the suction pressure distribution and injection pressure distribution around the cauterization electrode is possible, rather than simply adding a gas suction means or a gas injection means. Therefore, the positive pressure injection means and the negative pressure suction means that can act organically without any deterioration in the performance of each must be configured.

It is an object of the present invention to effectively extinguish the bleeding generated at the treatment site using only a positive pressure gas without using water as an injection medium in a conventional electronic cauterizer for cutting the affected part exposed to the outside air, and further comprising the gas injection means. This is a hand tool that can effectively inhale even the smoke generated in the process of pressing and uninterrupted by a single hand tool. It is to provide an intelligent suction, injection coupling means that can flexibly respond to the angle, depth, and the like.

The technical idea of the present invention for solving the above problems is as follows.

First, the suction port 20 and the gas injection port 21 are disposed at the root portion of the cauterized electrode 11 of the electric cauterizer, but basically the suction port 20 is disposed above the electrode, and the gas injection port 21 is positioned below the electrode. To be placed. This is basically the best way to push down the blood flowing from the treatment area while sucking up the smoke, assuming that the cauterizer is angled and cut and hemostatic.

Next, the suction port 20 and the gas injection port 21 can be stretched and reduced by simply pulling out and inserting the extension suction pipe 30 and the extension injection pipe 31 in the nail with the nail during the operation of the electrocautery. Also, it was possible to turn right and left with a finger during the operation. For this purpose, a flexible hose type suction and discharge hose is directly connected to the suction port and the gas injection port. In this case, it is possible to selectively bring more necessary parts closer to the treatment site in a specific work, and can perform the desired work alternately (cutting or hemostasis), regardless of the position and depth of the cauterizing electrode 11, slope and direction. Suction and injection direction can be adjusted.

In addition, the suction port 20 and the gas injection port 21 may be fitted with a secondary extension tube of the fitting type. The fitting suction pipe 40 and the fitting injection pipe 41, which are secondary extension pipes, may be arranged to face each other as much as possible, for example, each of the inlet and the outlet, and in this case, the smoke scattered in the spraying direction due to the injecting gas which pushes out blood. It can more effectively suck in and splashing blood. These fitting tubes may cause the user to be distracted by covering the cauterized electrode in the field of view or directly touching the affected part, but in the present invention, the suction port 20 and the gas jet port 21 are rotated to the cauterized electrode by the rotary base 25. The fitting tubes can also lie on the left and right sides of the affected area because they can be deflected. Therefore, it does not cause the inconvenience mentioned above.

In addition, in the present invention, the suction port 20 may be fitted with a transparent expanded suction tube 50 having a wide and flat shape similar to the suction port of the vacuum cleaner, if necessary. When the transparent suction tube is fitted, it can more effectively absorb the scattering of smoke and blood, so that the gas injection pressure under the cauterizing electrode can be further increased, which is necessary to cut out or bleed a large range at a rigid angle rather than fine and free movement. It is useful for speeding up work when there is.

Although the present invention has a limitation in that water is not released when a simple cautery procedure is performed on tissues exposed to outside air such as skin, it is possible to effectively perform the function of removing smoke and securing the bleeding field using only gas inhalation and injection. Can be.

In addition, in the process by the additional suction means and the injection means disclosed in the present invention the electronic dust generator of the present invention can exhibit a variety of suction and gas injection patterns irrespective of the working field and the working angle, accordingly the smoke by gas injection There is an effect that enables easy and smooth electrocautery without the bleeding staying in the treatment part because the back suction is scattered or the kinetic energy of the injected gas is lost due to the negative pressure of the suction port.

With reference to the embodiment of the present invention included in the drawings in order to technically support the above-described solution of the present invention will be described in detail.

However, in the following specific embodiments, the components including the specific terminology and combinations thereof do not limit the technical spirit inherent in the present invention.

1 to 6 show only the handtool part containing the technical features of the present invention among the conventional electric cauterizers. Parts not shown in the drawings are the same as those of the conventional electric cauterizer configuration, or a control box for controlling the suction, gas injection configuration and corresponding functions is added to the conventional configuration.

In a typical electric cauterizer, the cauterization electrode 11 receives AC current from a power supply device that generates an AC voltage of high frequency, and generates heat by contact resistance at a minute portion contacting the body tissue. At this time, a secondary ground point for returning the current input slightly away from the treatment site may be connected. By controlling the voltage, current, and alternating current frequency of the power supply, the energization energy of the contact portion can be controlled and the tissue can be cut out with strong heat (cutting) or the tissue can be pressed with heavier heat (hemostasis). This minimizes the need for sophisticated work on weak, loose tissues. In this process, the suction of negative pressure may be set to a strong suction pressure capable of inhaling blood and other liquids, or a weak suction pressure capable of inhaling only tissue burning smoke.

Positive pressure injection may also be set at a strong injection pressure to disperse both blood and smoke strongly using normal air or non-combustible, inert gas, or at a weak injection pressure to force only the blood at the bleeding site Can be set.

The present invention is basically intended for the electrocautery to apply the electrocauterization action to the treatment site exposed to the outside air, and the application is excluded from electrocautery accompanied by strong water spray and strong liquid inhalation, such as in laparoscopic surgery.

1 to 3 show a first embodiment which is a basic embodiment of the electric cauterizer of the present invention.

The cauterized electrode 11, which is supplied from the power supply by wire or wirelessly, is attached to one end of the body 10, and the suction port 20 and the gas injection port (circle) around the root portion of the cauterized electrode 11 in the body. 21 are arranged respectively.

The suction port 20 is connected to the suction hose 23 for supplying the suction pressure of the negative pressure and the discharge hose 24 for supplying a positive pressure gas to the gas injection port 21 is connected to the suction port and the injection port It is made of flexible material to cope with the rotational movement and is fixed while being wound along the body circumference.

The first control unit 12 for controlling the power and the second control unit 13 for controlling the suction pressure and the amount of gas supplied to the body 10 are provided with two buttons, respectively. If the selective operation method of dividing the operation mode into cutting and hemostasis by adjusting the control unit, the second operation unit is an operation method capable of performing both selection and joint actions such as suction or injection or a combination of suction and injection. This is a conceptual differentiation compared to the prior art which employs only one means of normal suction and injection.

Figures 3a, 3b, 3c to provide a technical basis that the inhalation and gas injection action can proceed in some cases in the present invention. Referring to the drawings, the suction port 20 and the gas injection port 23 are basically arranged on opposite sides with respect to the cauterization electrode 11.

The suction port 20 or the gas injection port 21 is formed of a double tube including an extension suction pipe 30 or an extension injection pipe 31, respectively, so as to selectively extend or contract in the longitudinal direction of the cauterization electrode 11. The length of the suction port and the jet port can be different from each other by simply extracting the extension pipe and the extension pipe in the form of the inner tube inserted into the outer tube (suction port, gas injection port) with nails. The intensity is very immediate and flexible.

In addition, the suction port 20 and the gas injection port 21 are coupled to the body 10 through the rotary base 23 so as to rotate about the cauterization electrode 11 by a user's manipulation. The inlet arrangement can be rotated by simply turning the cylindrical intake / exhaust module combined with the gas nozzles with the fingertips, and the inclination and direction of the cauterization electrode can also be controlled very flexibly.

For example, the upper and middle views of FIG. 3A work while turning the gas injection port and the extension injection pipe 31 extending in front of the cauterizing electrode 11 from side to side while reducing suction and increasing gas injection. This is the case of a cutting procedure where the action of pushing the bleeding sideways is important.

In addition, the bottom view of FIG. 3A focuses on suction and reduces gas injection while turning the suction inlet and the extension suction pipe 30 extending in front thereof to the left and right of the cauterization electrode 11. This case is a case of hemostatic procedure in which smoke inhalation is important.

3b and 3c show how the user can turn the suction inlet and the gas injection port coupling module attached to the rotary base 25 by using.

Figure 4 shows a case in which the intake and exhaust tube can be inserted without disturbing the field of view corresponds to a second embodiment of the present invention.

Referring to FIG. 4, the openings of the suction port 20 or the gas injection port 21 may be selectively extended in the longitudinal direction of the cauterizing electrode 11 or may be opened in a direction different from that of the cauterizing electrode 11. The fitting suction pipe 40 or the fitting injection pipe 41 is fitted. In any case, it can be seen that the injected positive pressure gas may partially flow into the inlet of the negative pressure, or the inlet of the negative pressure is arranged to suck smoke, bleeding, and the like without being disturbed by the positive pressure injection. Even in this case, the user can smoothly secure the field of view of the skin tissue in contact with the cauterizing electrode while rotating the suction inlet and the gas injector module, and can also prevent the affected area from touching the fitting injection tube 41 by lying on its side. have.

5 shows a second embodiment of the present invention. In FIG. 5, the suction inlet 20 further extends in the longitudinal direction of the cauterization electrode 11, and is further coupled with an enlarged suction tube 50 made of a transparent material, in which case the inlet port covers the catheter electrode wider. Compared with the example, even if a gas of relatively higher pressure is injected, the smoke can be inhaled without difficulty. However, since the movement of the cauterized electrode is greatly limited and the field of view is also limited, it is effective when only a long straight line is cut or a simple and consistent operation is required.

FIG. 6 is an exploded perspective view showing all the components of the present invention except for the enlarged suction pipe 50. The hoses may be arranged behind the body in the case of left-handed, in which case the inlet 20 and the gas nozzle 21 may be replaced. (The position of the connection hole with the hose can be changed.) The rotatable base 25 can be strongly pressed into the body, and is provided with a fixing groove for fixing the bottom surface of the suction port and the gas injection port.

It is effective that the second operation unit for manipulating the suction and the injection pressure of the operation unit transmits a signal along the wire 14, and the hoses 23 and 24 are combined to be responsible only for the suction and injection of the gas.

The extension suction pipe 30 and the extension injection pipe 31 may be inserted into and drawn out of the inlet 20 and the gas injection port 21 which are outer pipes, respectively, and the fitting suction pipe 40 may be covered by the extension suction pipe 30. It is fitted while being built, the fitting injection pipe 41 is a structure that can be fitted while being covered with the extension injection pipe (41). All components are made of light, solid and reliable structure, so that user's operation ability can be maximized.

While the embodiments of the present invention have been described in detail with reference to the drawings, the technical spirit of the present invention is not limited to the above embodiments.
