Electrosurgical device with step-by-step suction control

[0001] The present invention relates to an electrosurgical device capable of step-by-step suction control, and more specifically, to an electrosurgical device capable of step-by-step suction control, which adjusts suction pressure in steps when cutting or coagulating human tissue using an electrode tip, so that the procedure can be performed in an optimal state without damaging the human tissue, and further, to an electrosurgical device capable of step-by-step suction control, which allows the horizontal and vertical positions of an electrode tip formed in a rectangular tube shape to be easily adjusted according to the situation, so that the procedure can be performed more conveniently.

[0002] In general, surgical procedures on internal parts of the human body require incision, coagulation, or suction of the surgical site, and various types of electrosurgical devices for this purpose are known and applied in this field.

[0003] These electrosurgical devices can easily position the front end of a radio frequency electrode probe that can generate radio frequency energy (RF energy) during surgery to treat the affected area, and use the radio frequency energy to cut or coagulate the affected area.

[0004] These electrosurgical devices allow the operator to remove only locally selected lesions, and by controlling the amount and depth of delivered energy, only the desired lesion area can be treated without damaging the surrounding tissue.

[0005] Conventional electrosurgical devices only control the on / off of a very small exhaust hole when suctioning, so there was a problem in that the suction pressure could not be precisely controlled.

[0006] In addition, conventional electrosurgical devices had a problem in that they caused fatigue to the user by twisting the user's wrist when changing the direction of the electrode tip connected to the tip of the electrode probe.

[0007] The present invention has been devised in consideration of the above problems,

[0008] The first purpose of the present invention is to provide an electrosurgical device capable of step-by-step suction control, which allows the procedure to be performed in an optimal state without damaging human tissue by adjusting the suction pressure step-by-step when cutting or coagulating human tissue using an electrode tip.

[0009]

[0010] A second object of the present invention is to provide an electrosurgical device capable of step-by-step suction control, which allows for easier adjustment of the horizontal and vertical positions of an electrode tip formed in the shape of a rectangular tube according to the situation, thereby making the procedure more convenient.

[0011] According to the features for achieving the above-mentioned purpose, the first invention relates to an electrosurgical device capable of step-by-step suction control, and is characterized by comprising: a main body having a suction channel formed therein; a hollow electrode probe coupled to one end of the main body and having a suction hole therein communicating with the suction channel; an electrode tip coupled to one end of the electrode probe for cutting or coagulating human tissue by high frequency; and a suction control means provided on the main body for step-by-step adjusting the suction strength by a user's operation.

[0012]

[0013] The second invention is characterized in that, in the first invention, the electrode tip has a suction function in the shape of a rectangular tube.

[0014]

[0015] The third invention is characterized in that, in the second invention, the electrode probe has a rotary knob exposed on the main body so as to change the direction of the electrode tip, and a smoke hole is further formed at the tip so that smoke generated when cutting and coagulating human tissue can be sucked.

[0016]

[0017] The fourth invention is characterized in that, in the first invention, the suction control means comprises a casing formed with a valve groove and an exhaust hole through which suction pressure is exhausted, which is provided integrally with the main body and communicates with a branched suction path, a valve plug flexibly installed inside the casing to open and close the valve groove, and a rotary lever that controls the positional movement of the valve plug from the outside of the main body to adjust the opening of the valve groove in stages.

[0018]

[0019] The fifth invention is characterized in that, in the fourth invention, the valve plug and the valve groove have a tapered close-fitting structure so that the suction pressure is precisely adjusted according to the gap therebetween.

[0020]

[0021] The sixth invention is characterized in that, in the fourth invention, the valve plug has an operating rod that comes into contact with the rotary lever, and level grooves of different depths that come into contact with the operating rod are further formed on the circumference of the rotary lever.

[0022] According to the electrosurgical device capable of step-by-step suction control of the present invention, when cutting or coagulating human tissue, the suction pressure is adjusted step-by-step through the suction control means, thereby enabling the procedure to be performed in an optimal state without damaging human tissue.

[0023] Additionally, the rotary knob exposed on the main body can be easily adjusted with one hand to change the electrode tip horizontally or vertically according to the treatment situation, making the treatment more convenient.

[0033]

[0034] Hereinafter, an electrosurgical device capable of step-by-step suction control according to the present invention will be described in detail with reference to the attached drawings.

[0035] FIG. 1 and FIG. 2 are perspective views of an electrosurgical device capable of step-by-step suction control according to the present invention, FIG. 3 is an enlarged perspective view and a cross-sectional view of an electrode pro and an electrode tip extracted from FIG. 1, FIG. 4 is a cross-sectional view illustrating a suction control means extracted from FIG. 1, and FIG. 5 is an operation diagram illustrating the operation of the suction control means of FIG. 4.

[0036] As illustrated in FIGS. 1 to 5, the present invention relates to an electrosurgical device capable of step-by-step suction control, which allows for performing a procedure in an optimal state without damaging human tissue by adjusting suction pressure step-by-step when cutting or coagulating human tissue using an electrode tip, and also allows for performing a procedure more conveniently by easily adjusting the horizontal and vertical positions of an electrode tip formed in a rectangular tube shape according to the situation.

[0037] The electrosurgical device capable of step-by-step suction control of the present invention is composed of four parts: a main body (10), an electrode probe (20), an electrode tip (30), and a suction control means (40).

[0038] The above main body (10) is configured with a suction path (11) formed inside, and can be configured with a connector (12) formed to connect to a suction hose (not shown).

[0039] In addition, the main body (10) may be configured with a plurality of operation buttons (13) that can control the high frequency intensity transmitted to the electrode tip (30) when cutting and coagulating human tissue by the user's operation, and a power supply means (not shown) may be built in.

[0040] The above electrode probe (20) is connected to one end of the main body (10) as shown in Fig. 3 and has a hollow shape with a suction hole (24) inside that communicates with the suction path (11).

[0041] The above electrode probe (20) is made of STS304 material and has the function of transmitting high frequency to the electrode tip (30).

[0042] In addition, the electrode probe (20) may be configured with a PTFE (polytetrafluoroethylene: Teflon) heat shrink tube (22) on the outer surface to prevent high frequency from being radiated to the outside.

[0043] In addition, the electrode tip (30) is connected to one end of the electrode probe (20) and has the function of cutting or coagulating human tissue by high frequency.

[0044] The above electrode tip (30) is also made of STS304 material, and can be configured to be easy to clean by coating an ETFE (Ethylene Tetrafluoroethylene) layer (31) in the form of a film on the outer surface except for the tip.

[0045] Here, the electrode tip (30) is formed in a rectangular tube shape and can function to cut or coagulate human tissue simultaneously with suction.

[0046] Meanwhile, the tip of the electrode probe (20) may be configured with a smoke hole (23) formed therein so that smoke generated when cutting and coagulating human tissue using the electrode tip (30) can be sucked out.

[0047] The above smoke hole (23) may be formed as a single hole or multiple holes, and it is preferable to form it as a single hole to prevent the local suction pressure through the electrode tip (30) from decreasing.

[0048] In addition, the electrode probe (20) has a structure having a rotation knob (21) exposed on the main body (10) so as to be able to change the direction of the electrode tip (30) to a horizontal or vertical direction.

[0049] The above-mentioned rotary knob (21) is connected to the other side of the electrode probe (20) and is structured to be exposed to the outside on one side of the main body (10).

[0050] At this time, the main body (10) may be configured with a cutout (13) formed to eliminate rotation interference of the rotary knob (21).

[0051] Through this, a structure can be provided that allows the electrode tip (30) to be easily adjusted horizontally / vertically with one hand according to the treatment situation, making the treatment more convenient.

[0052] For example, as shown in Fig. 1, when cutting human tissue, the direction of the electrode tip (30) can be changed to the vertical direction by operating the rotary knob (21), and when coagulating human tissue, as shown in Fig. 2, the direction of the electrode tip (30) can be changed to the horizontal direction to coagulate a wide range of human tissue.

[0053] The above suction control means (40) is provided externally to the main body (10) and has the function of controlling the suction strength in stages by the user's operation.

[0054] Specifically, when cutting or coagulating human tissue using the electrode tip (30), the suction control means (40) controls the suction pressure in stages to allow the procedure to be performed in an optimal state without damaging the human tissue.

[0055] The above suction control means (40) may be composed of a casing (41), a valve plug (42), and a rotary lever (44), as shown in FIG. 4.

[0056] The above casing (41) is provided integrally with the main body (10) and is connected to a branch channel (111) that branches off from the suction channel (11).

[0057] At this time, the casing (41) may be further configured with a valve groove (411) that is opened and closed by a valve plug (42) and an exhaust hole (412) through which suction pressure is exhausted.

[0058] The above valve plug (42) is elastically installed inside the casing (41) by a spring (43) and functions to close the valve groove (411).

[0059] The above valve plug (42) has a structure having an operating rod (421) that comes into contact with the rotary lever (44) at the other end.

[0060] At this time, the valve plug (42) and the valve groove (411) have a tapered close-fitting structure, and the suction pressure is precisely controlled by the amount of suction discharged to the exhaust hole (412) according to the gap between them.

[0061] The above rotary lever (44) controls the positional movement of the valve plug (42) outside the main body (10) to adjust the opening of the valve groove (411) in stages, thereby precisely controlling the suction pressure.

[0062] Here, the circumference of the above-mentioned rotary lever (44) may be configured with level grooves (441) of different depths that come into contact with the operating rod (421).

[0063] Accordingly, the user can precisely adjust the opening of the valve groove (411) by rotating the rotary lever (44) by hand, and the valve plug (42) moves in position inside the casing (41) according to the depth of the level groove (441) that comes into contact with the operating rod (421) of the valve plug (42).

[0064] As shown in (a) of Fig. 5, when the operating rod (421) comes into contact with the level groove (441) having the greatest depth, the valve plug (42) can be controlled to increase the gap with the valve groove (411) to increase the exhaust volume and thereby decrease the suction pressure.

[0065] Conversely, as in (b) of Fig. 5, when the operating rod (421) comes into contact with the level groove (441) having the smallest depth, the valve plug (42) can be controlled to close the valve groove (411) and thereby increase the suction pressure.

[0066] In an embodiment of the present invention, a total of four level grooves (441) are formed, and the smallest level groove (441) can generate the greatest suction pressure, and the largest level groove (441) can generate the least suction pressure, thereby enabling the procedure to be performed in an optimal state without damaging human tissue depending on the situation.

[0068] The embodiments described in this specification and the configurations illustrated in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention. Therefore, it should be understood that there may be various equivalents and modified examples that can replace them at the time of filing this application.
