Description

Electrosurgical device having a locking member for adjusting the position of the blade

[0001] The present invention relates to an electrosurgical device having a locking member for adjusting the position of a blade, and more specifically, to an electrosurgical device having a locking member for adjusting the position of a blade that enables the position of the blade to be adjusted so that the total length of the blade protruding from the main body can be easily and quickly adjusted.

[0002] Recently, with the growing interest in non-invasive treatment methods rather than surgical procedures, the use of electrotherapy in surgical operations is rapidly increasing. In particular, high-frequency electrosurgical units (ESUs) are primarily used in surgical procedures to incise parts of human tissue or coagulate tissue and blood using electricity, instead of a surgical scalpel.

[0003] These electrosurgical devices utilize the principle of generating short sparks or heat without giving electric shock or stimulation to the muscles when high-frequency current flows through the human body. During surgical procedures, they are used to cut parts of human tissue with high-frequency energy of about 100°C or to coagulate parts of human tissue with high-frequency energy of about 60°C to stop or reduce bleeding.

[0004] Meanwhile, conventional electrosurgical devices perform cutting or coagulation operations by having a blade come into contact with human tissue, and the length of the blade protruding from the outside of the main body must vary depending on the location of the procedure. For example, when the blade must be inserted deep into the human body, the blade must be relatively longer, and when the blade must be used on the surface of the human body, the blade must be relatively shorter.

[0005] Accordingly, conventionally, multiple electrosurgical devices with different blade lengths are provided and used. However, this has the problem that it causes inconvenience to users and makes it difficult to respond quickly during emergency surgeries, as users, such as doctors, must provide multiple electrosurgical devices with different blade lengths in a complex operating room and switch the devices individually according to the situation.

[0006] The objective of the present invention, which is to solve the problems of the prior art as described above, is to provide an electrosurgical device having a locking member for positioning a blade, which enables the length adjustment of a length adjustment part to which the blade is connected, thereby allowing the total length of the blade protruding outside the main body to be easily and quickly adjusted.

[0007] To achieve the above objective, the present invention provides an electrosurgical device having a locking member for adjusting the position of a blade, comprising: a main body formed in a long shape along the longitudinal direction and having a space inside; a length adjustment part installed to be movable along the space and having a plurality of locking parts formed along one longitudinal direction; a blade formed such that one side is coupled to the length adjustment part and the other side is extended to be exposed toward the outside of the main body; and a locking member for controlling the movement of the length adjustment part, wherein the locking member comprises: a stopper installed to perform a seesaw motion in an exposed hole formed through one side of the main body so that the locking part is exposed to the outside; and a sliding button part disposed to be slidable on the upper side of the stopper, wherein when the sliding button part slides and presses the stopper, the stopper performs a seesaw motion to be caught on the locking part.

[0008] Additionally, the stopper comprises a rotating shaft rotatably disposed above the exposed hole, a stop guide portion extending to cover the exposed hole on one side of the rotating shaft, a stop projection extending downwardly from the stop guide portion, and a stop release portion formed on the other side of the rotating shaft, wherein when the sliding button portion slides in one direction and presses the stop guide portion downwardly, the stop projection is guided to engage with the catch portion, and when the sliding button portion slides in the other direction and presses the stop release portion downwardly, the stop projection is guided upwardly from the catch portion. The present invention provides an electrosurgical device having a locking member for adjusting the position of a blade.

[0009] Additionally, the above-described sliding button portion comprises a button formed such that its lower side is disposed inside the main body and its upper side is exposed to the upper part of the main body, a connecting portion located below the button and guiding the rotation axis, a first pressing portion formed protruding to face the stop guide portion on one side of the connecting portion, and a second pressing portion formed protruding to face the stop release portion on the other side of the connecting portion, wherein when the sliding button portion slides in one direction, the first pressing portion presses the stop guide portion downward, and when the sliding button portion slides in the other direction, the second pressing portion presses the stop release portion downward. The present invention provides an electrosurgical device having a locking member for adjusting the position of a blade.

[0010] Additionally, an electrosurgical device having a locking member for adjusting the position of a blade is provided, characterized in that a concave movement guide is formed on the lower side of the connecting part, and a locking guide groove and an unlocking guide groove are formed on the upper inner side of the movement guide, respectively, along the movement direction of the sliding button part, so as to be spaced apart from each other, and when the sliding button part slides in one direction, the rotation axis is guided to be inserted into the locking guide groove, and when the sliding button part slides in the other direction, the rotation axis is guided to be inserted into the unlocking guide groove.

[0011] Additionally, the lower side of the first pressure member includes a first pressure guide member connected to the connecting member and a first inclined member that slopes upward as it moves away from the first pressure guide member, and the lower side of the second pressure member includes a second pressure guide member connected to the connecting member and a second inclined member that slopes upward as it moves away from the second pressure guide member; and when the sliding button member slides in one direction, the first pressure guide member presses the stop guide member downward and the stop release member rises to become closer to the second inclined member, and when the sliding button member slides in the other direction, the second pressure guide member presses the stop release member downward and the stop guide member rises to become closer to the first inclined member. The present invention provides an electrosurgical device having a locking member for adjusting the position of a blade.

[0012] Additionally, the present invention provides an electrosurgical device having a locking member for adjusting the position of a blade, characterized in that side walls are provided along the longitudinal direction of both inner sides of the moving guide, and when the sliding button part is slid, the rotation axis slides along the side walls.

[0013] Additionally, the present invention provides an electrosurgical device having a locking member for adjusting the position of a blade, characterized in that a pair of support protrusions are formed protrudingly on both sides of the exposed hole, a rotation guide groove is formed concavely in the support protrusions so that the rotation axis is inserted therein, and when the rotation axis is inserted into the rotation guide groove, a stop guide insertion part and a stop release insertion part are formed respectively in the stop guide part and the stop release part so that the upper side of the support protrusion is inserted therein.

[0014] The present invention allows the position of the blade exposed to the front of the main body to be adjusted using a length adjustment part to which the blade is connected, thereby having the effect of easily and quickly adjusting the total length of the blade protruding from the main body.

[0015] Furthermore, since the movement of the length adjustment unit can be controlled or permitted with a simple motion of sliding the sliding button unit forward or backward, it has the effect of enabling rapid operation of the length adjustment unit with a simple structure. In addition, as the operation of the length adjustment unit becomes easier and simpler, the possibility of errors during surgery is reduced, and surgical time can be shortened.

[0016] In addition, when the sliding button part is moved forward or backward, the rotation axis is inserted into the locking guide groove or the unlocking guide groove and engages in a locking mechanism, thereby having the effect of restricting the unauthorized movement of the sliding button part.

[0017] In addition, since the first and second inclined sections guide the stop guide section or the stop release section to rise, there is an effect of preventing interference during the seesaw motion of the stopper.

[0018] In addition, since the stop guide and stop release sections are formed with a width greater than that of the rotation axis, the overall surface area is increased, which has the effect of allowing the sliding button section to stably press the stop guide and stop release sections.

[0019] In addition, when the sliding button part slides, the rotation axis slides stably along the side wall, so the sliding button part moves stably without left-right shaking.

[0029] Hereinafter, an electrosurgical device having a locking member for adjusting the position of a blade according to a preferred embodiment of the present invention will be described in more detail with reference to the attached drawings.

[0030]

[0031] In the present invention, the front or front side refers to the direction of the blade, and the rear or rear side refers to the direction of the smoke evacuator.

[0032]

[0033] FIG. 1 is a drawing illustrating an electrosurgical device having a locking member for adjusting the position of a blade according to a preferred embodiment of the present invention, and FIG. 2 is a disassembled drawing illustrating an electrosurgical device having a locking member for adjusting the position of a blade according to a preferred embodiment of the present invention.

[0034] Referring to FIGS. 1 and 2, an electrosurgical device having a locking member for positioning a blade according to a preferred embodiment of the present invention includes a main body (100), a length adjustment part (200), a blade (300), and a locking member (400).

[0035] The main body (100) is formed in a long shape along the longitudinal direction so that a user can grip it with their hand. The main body (100) is formed by combining a first side body (110) and a second side body (120) to form an external shape, and a space portion (122) of an empty space is formed along the internal longitudinal direction of the first and second side bodies (110, 120). Additionally, an exposure hole (124) is formed through the upper front side of the first and second side bodies (110, 120) so that a locking portion (202, see FIG. 3), which will be described later, is exposed to the outside. Near the upper center of the first and second side bodies (110, 120), a substrate portion (150), such as a PCB (Printed Circuit Board), and an electrode connection portion (142) are arranged sequentially in the vertical direction. The substrate portion (150) is electrically connected to an external power source. A fixed electrode (152) electrically connected to a substrate (150) is disposed on the upper rear side of the first and second side bodies (110, 120).

[0036] Then, an upper body (130) is combined to cover the upper side of the first and second side bodies (110, 120). A button guide hole (132) is formed through the front side of the upper body (130) at a position corresponding to the exposure hole (124), and an operation guide hole (134) is formed through the center of the upper body (130) at a position corresponding to the electrode connection part (142). An operation part (140) is inserted into the operation guide hole (134) and is electrically connected to the electrode connection part (142). Then, when the user operates the control unit (140), the electrode connection unit (142) transmits the result of the operation of the control unit (140) to the substrate unit (150), and the substrate unit (150) adjusts the amount of high-frequency energy received from the outside and transmits it to the blade (300) described later through the fixed electrode (152: shown in FIG. 9) and the movable electrode (310: shown in FIG. 9). The fixed electrode (152) and the movable electrode (310) will be explained in FIG. 9.

[0037] The length adjustment section (200) is formed in a long shape so that it can move while located inside the space section (122). A plurality of locking sections (202) are formed along the upper length direction of the length adjustment section (200) from front to rear. The locking sections (202) may be formed, for example, as intaglio (or relief). A suction section (210, see FIG. 5) that serves as a passage for air to move along the interior of the length adjustment section (200) is formed. The front side of the length adjustment section (200) is formed to protrude so as to be exposed to the front of the main body (100). A suction means (not shown), such as a smoke evacuator, is connected to the rear side of the length adjustment section (200) to suck in air, so that when a user uses the blade (300) to cut or coagulate a part of the patient's body tissue, smoke generated around the blade (300) is sucked into the suction means through the suction section (210).

[0038] The blade (300) is formed to be long along the longitudinal direction, and one side of the blade (300) is connected to the inner front side of the length adjustment unit (200), so that the length of the blade is extended or shortened together with the horizontal movement of the length adjustment unit (200). At this time, an internal connection unit (212: shown in FIG. 9) is formed on the inner front side of the suction unit (210), and one side of the blade (300) is connected to the internal connection unit (212). Then, high-frequency energy transmitted from the outside is delivered to the blade (300), and a part of the patient's body tissue is cut or coagulated using the high-frequency energy.

[0039] The locking member (400) is for controlling the movement of the length adjustment part (200) and includes a stopper (410) configured to engage or disengage from the locking part (202), and a sliding button part (420) installed on the upper body (130) to operate the stopper (410). The stopper (410) is installed to perform a seesaw motion in the exposed hole (124) where the locking part (202) is exposed to the outside. The sliding button part (420) is positioned to be slidable on the upper side of the stopper (410). Below, the detailed structure of the locking member (400) will be described.

[0040]

[0041] FIG. 3 is a disassembled drawing of a locking member according to a preferred embodiment of the present invention.

[0042] Referring to FIGS. 2 and 3, the locking member (400) includes a stopper (410) formed to enable seesaw movement and a sliding button part (420) that slides in the forward and backward direction on the upper side of the stopper (410).

[0043] The first and second side bodies (110, 120) have a pair of supporting protrusions (126) formed protruding from both sides of the exposed hole (124), and a concave rotation guide groove (126a) is formed in the supporting protrusions (126).

[0044] The stopper (410) includes a rotating shaft (412) rotatably positioned on the upper side of the exposed hole (124), a stop guide portion (414) extended to cover the exposed hole (124) on one side of the rotating shaft (412), a stop projection (415) extended downward on the stop guide portion (414), and a stop release portion (416) formed on the other side of the rotating shaft (412).

[0045] The rotation shaft (412) is positioned to be rotatable while inserted into the rotation guide groove (126a). The stop guide (414) and the stop release part (416) are formed to have a width greater than the length of the rotation shaft (412). Since the stop guide (414) and the stop release part (416) are formed with a width greater than that of the rotation shaft (412), the total surface area is increased, thereby enabling the sliding button part (420), which will be described later, to stably press the stop guide (414) and the stop release part (416). And since the stop guide part (414) and the stop release part (416) are formed to be larger than the rotation axis (412), when the rotation axis (412) is inserted into the rotation guide groove (126a), the stop guide insertion part (414a) and the stop release insertion part (416a) are respectively formed through the stop guide part (414) and the stop release part (416) so that the upper side of the support protrusion (126) is inserted therein.

[0046]

[0047] FIG. 4 is a drawing showing the state in which a sliding button part according to a preferred embodiment of the present invention is coupled to a stopper, and FIG. 5 is a cross-sectional drawing showing the state in which a locking member according to a preferred embodiment of the present invention is coupled.

[0048] Referring to FIGS. 2 to 5, the sliding button portion (420) includes a button (422), a connecting portion (424), a first pressing portion (426), and a second pressing portion (428). The button (422) is positioned inside the main body (100) so that its lower side faces the exposure hole (124), and its upper side is formed to protrude so as to be exposed to the upper part of the main body (100) by passing through the button guide hole (132). At this time, the button guide hole (132) is formed to be long in the longitudinal direction, and the button (422) is formed to slide along both sides of the button guide hole (132) in the front-rear direction of the main body (100).

[0049] The connecting part (424) is located below the button (422) and guides the rotation axis (412). At this time, a concave movement guide part (424a) is formed on the lower side of the connecting part (424) so ​​that the rotation axis (412) can move while guided, and a locking guide groove (424c) and an unlocking guide groove (424b) are formed on the upper inner side of the movement guide part (424a) so as to be spaced apart from each other along the direction of movement of the sliding button part (420). The locking guide groove (424c) and the unlocking guide groove (424b) are each formed concavely so that the rotation axis (412) can be inserted. The locking guide groove (424c) is positioned behind the unlocking guide groove (424b).

[0050] In addition, side walls (424d) are provided along the longitudinal direction of both inner sides of the movement guide (424a), and when the sliding button part (420) is slid, the rotation axis (412) slides stably along the side walls (424d). Since both ends of the rotation axis (412) slide stably along the side walls (424d) in this manner, the sliding button part (420) has the effect of moving stably without left-right shaking.

[0051] The first pressure section (426) is formed facing the stop guide section (414) on the front side of the connecting section (424). The lower side of the first pressure section (426) includes a first pressure guide section (426a) connected to the connecting section (424), and a first inclined section (426b) formed to be inclined upward as it moves away from the first pressure guide section (426a).

[0052] The second pressure section (428) is formed to face the stop release section (416) at the rear side of the connecting section (424). The lower side of the second pressure section (428) includes a second pressure guide section (428a) connected to the connecting section (424), and a second inclined section (428b) formed to be inclined upward as it moves away from the second pressure guide section (428a).

[0053] And the first pressure guide section (426a) is integrally connected to the front side of the connecting section (424), and the second pressure guide section (428a) is integrally connected to the rear side of the connecting section (424). And the front side of the movement guide section (424a) extends past the front side of the connecting section (424) toward the center of the first pressure guide section (426a), and the rear side of the movement guide section (424a) extends past the rear side of the connecting section (424) toward the center of the second pressure guide section (428a). That is, the front side of the movement guide section (424a) is located in the center between the two sides of the first pressure guide section (426a), and the rear side of the movement guide section (424a) is located in the center between the two sides of the second pressure guide section (428a).

[0054]

[0055] FIG. 6 is a drawing illustrating a state in which a locking member according to a preferred embodiment of the present invention controls the movement of a length adjustment part, and FIG. 7 is a drawing illustrating a state in which a locking member according to a preferred embodiment of the present invention allows the movement of a length adjustment part.

[0056] First, referring to FIG. 6, when the user presses the button (422) forward, the sliding button part (420) slides forward. At this time, the rotation axis (412) is guided to be inserted into the locking guide groove (424c), and the first pressure guide part (426a) of the first pressure part (426) presses the stop guide part (414) downward. Then, the stop guide part (414) moves in a seesaw motion in one direction to rotate downward, thereby moving the stop projection (415) downward. The stop projection (415) is then guided to be caught on the locking part (202), thereby restricting the movement of the length adjustment part (200). At this time, the stop release part (416) is raised so as to be close to the second inclined part (428b). That is, when the stop guide (414) is rotated downward, the second inclined part (428b) provides space for the stop release part (416) to rise.

[0057] As such, the present invention allows the movement of the length adjustment part (200) to be controlled by sliding the sliding button part (420) forward, thereby providing the effect of easily fixing the length adjustment part (200) with a simple structure. In addition, when the sliding button part (420) moves forward, the rotation shaft (412) is inserted into the locking guide groove (424c) and engaged, so the sliding button part (420) is restricted from moving backward without intentional operation by a doctor, thereby preventing the length adjustment part (200) from moving arbitrarily.

[0058]

[0059] Next, referring to FIG. 7, when the user presses the button (422) backward, the sliding button part (420) slides toward the rear, the rotation shaft (412) is inserted into the release guide groove (424b), and the second pressure guide part (428a) of the second pressure part (428) presses the stop release part (416) downward. Then, the stop release part (416) moves in a seesaw motion in the other direction to rotate downward, and the stop projection (415) is moved upward. The stop projection (415) is then guided to the upper part of the locking part (202), allowing the length adjustment part (200) to move. At this time, the stop guide part (414) is raised so as to be close to the first inclined part (426b). That is, when the stop release part (416) is rotated downward, the first inclined part (426b) provides space for the stop guide part (414) to rise.

[0060] As such, the present invention allows the movement of the length adjustment part (200) to be controlled or allowed by sliding the sliding button part (420) forward or backward, thereby having the effect of allowing the length adjustment part (200) to be operated with a simple structure. In addition, when the sliding button part (420) moves forward or backward, the rotation axis (412) is inserted into the locking guide groove (424c) or the unlocking guide groove (424b) and engaged, thereby having the effect of restricting unintended arbitrary movement of the sliding button part (420). Furthermore, since the first and second inclined parts (426b, 428b) guide the stop guide part (414) or the stop release part (416) to rise, there is an effect of preventing interference during the seesaw motion of the stopper (410).

[0061]

[0062] FIG. 8 is a drawing illustrating the state in which the length adjustment part is moved forward according to a preferred embodiment of the present invention.

[0063] Referring to the drawing, the user inserts the blade (300) into the inside of the cut skin (S) while holding the main body (100). At this time, the sliding button part (420) is slid backward so that the length adjustment part (200) protrudes forward of the main body (100), and then the sliding button part (420) is slid forward to lock the movement of the length adjustment part (200).

[0064] As such, the present invention allows the position of the blade (300) protruding forward of the main body (100) to be adjusted using the length adjustment part (200) to which the blade (300) is connected, thereby providing the effect of easily and quickly adjusting the total length of the blade (300) protruding out of the main body. In addition, since the movement of the length adjustment part (200) can be controlled or allowed by a simple operation of sliding the sliding button part (420), the structure becomes simpler and manufacturing and maintenance costs can be reduced. Furthermore, since the sliding button part (420) can be operated quickly, operation becomes easier and simpler, the possibility of errors during surgery is reduced, and the surgery time can be shortened.

[0065]

[0066] FIG. 9 is a cross-sectional view illustrating the state in which the length adjustment part according to a preferred embodiment of the present invention is moved forward.

[0067] Referring to FIG. 9, when the length adjustment unit (200) is moved forward, the blade (300) is electrically connected to the fixed electrode (152) through the movable electrode (310). That is, the fixed electrode (152) is formed long along the upper longitudinal direction of the first and second lateral bodies (110, 120). At this time, the upper rear side of the first and second lateral bodies (110, 120) is open so that the fixed electrode (152) is exposed toward the suction unit (210). Then, the movable electrode (310) is formed along the internal longitudinal direction of the suction unit (210). One side of the movable electrode (310) contacts the blade (300), and the other side of the movable electrode (310) passes through the suction unit (210) and is formed with a bent portion (312) so that it contacts the fixed electrode (152). At this time, the bending portion (312) is configured to slide along the fixed electrode (152), so that when the length adjustment portion (200) moves forward or backward, the bending portion (312) slides while in contact with the fixed electrode (152), so that the high-frequency energy transmitted by the substrate portion (150) passes through the fixed electrode (152) and the moving electrode (310) and is transmitted to the blade (300).

[0068]

[0069] Although the present invention has been described in detail in the above embodiments, it is obvious that the present invention is not limited thereto, and it is obvious to those skilled in the art that various modifications and variations are possible within the scope of the technical spirit of the present invention, and if such modifications and variations fall within the scope of the appended claims, the technical spirit thereof should also be considered to be within the scope of the present invention.
