[0001] The present invention relates to an endoscope control body having a rotary knob fixing switch, and more specifically, to an invention that improves the rotation accuracy and fixing structure of a wheel knob for changing the direction of an endoscope, thereby enabling easy operation of an endoscope camera and accurate observation of a patient's lesion.

[0002] In general, an endoscope is a medical device designed to observe organs that cannot be directly seen without surgery or an autopsy by inserting a machine. Depending on the type, the abdominal wall can be observed with a flash, the position of the camera can be adjusted, or it can be combined with a fiberscope to observe the inside of the organ and take pictures of the necessary parts.

[0003] In the process of performing a minimal examination or surgery using the above endoscope, the endoscope is structurally supported by a mechanical arm to quickly adjust the field of view of the endoscope while maintaining the safety of the endoscope, and the attending physician has a structure in which the endoscope is moved to an appropriate position through the mechanical arm by controlling the movement of the mechanical arm by operating the switch and knob of the controller.

[0004] However, the conventional endoscope control body has many buttons, switches and operating knobs located adjacent to each other, which causes inconvenience in use, and the operating knobs are located on one side, so there are cases where the operating knobs are unintentionally malfunctioned due to mistakes or slippage by the attending physician.

[0005] In particular, multiple buttons or switches, such as knob fixing switches, are installed in the control body for endoscopes. However, some of these buttons or switches have errors in their manufacturing process, resulting in a problem of reduced operational precision.

[0006] In order to solve the problems of the prior art as described above, the present invention aims to provide an endoscope control body with improved processability, precision, and durability by applying a new structure to a knob-fixing switch installed in a controller to reduce errors in manufacturing the knob-fixing switch.

[0041] Hereinafter, embodiments according to the present invention will be described in detail with reference to the attached drawings. In describing with reference to the attached drawings, identical or corresponding components are given the same drawing reference numerals and redundant descriptions thereof are omitted.

[0042] First, the control body knob device (100) for an endoscope according to the present invention is a device that is mounted to transmit a rotation input signal generated by a doctor manipulating a button and wheel knob provided in a controller housing (1) as shown in FIG. 1 to a control unit in order to quickly adjust the field of view of an endoscope while simultaneously maintaining the safety of the endoscope during a process of performing an examination or surgery using an endoscope, and has a structure in which the control unit operates a driving unit to move the endoscope to an appropriate position.

[0043] The above controller knob device (100) is configured by assembling a first assembly space (S1) and a second assembly space (S2) by assembling a damper bracket (20) in which a damper member (25) is assembled to a signal body base (10) in which a signal body member (15) is largely mounted, as shown in FIGS. 2 to 7, and assembling a first knob module (30a) for operating an endoscope in the up and down directions and a second knob module (30b) for operating an endoscope in the left and right directions.

[0044] The signal body base (10) is formed by bending and forming the base side plates (12) on both sides of the base connecting plate (11) to form an overall “∩” shape, so that the base connecting plate (11) is coupled to the inner wall of the controller housing (1), and a spring pressure pin (13) is protruded and formed on the facing inner wall surface of the base side plate (12), so that it is inserted into the first and second spring insertion portions (35b) of the first and second wheel knobs (31b) described later, thereby supporting one end of the first and second spring members (40b).

[0045] In addition, the signal body member (15) is respectively coupled to the base side plates (12) provided on both sides of the signal body base (10), so that the signal body fitting shafts (38) of the first and second wheel knobs (31b) are assembled to the signal body member (15), thereby having a configuration capable of transmitting a rotation input signal according to the rotation of the wheel knobs (30a, 30b) to the control unit (not shown). However, the configuration of the signal body member (15) can be applied in various ways according to the needs of those skilled in the art, and is not limited to a single configuration.

[0046] In addition, the signal body base (10) is provided in a pair of two pieces having an “L” shape in which a base side plate (12) is bent and formed on one side of a base connecting plate (11), and is arranged symmetrically to each other, and the damper support plate (21) of the damper bracket (20) is connected to the base connecting plate (11) to form an integral structure, which is also included in the present invention.

[0047] The damper bracket (20) fixes the damper support plate (21) to the base connecting plate (11), and the damper case (22) is placed in the space between the base side plates (12) to form a first assembly space (S1) and a second assembly space (S2) on both sides.

[0048] The damper case (22) formed on both sides of the above damper bracket (20) is formed to have a groove structure that is opened toward the base side plate (12), so that the damper member (25) can be assembled to the damper case (22), and the damper shaft (26) provided on one side of the damper member (25) is positioned in the direction of the base side plate (12).

[0049] Here, the damper bracket (20) is configured so that only the first assembly space (S1) is formed by placing the damper case (22) on one of the base side plates (12) while the damper support plate (21) is fixed to the base connecting plate (11), and the damper member (25) is assembled to the damper case so that only the first knob module (30a) is installed in the first assembly space (S1), which is also included in the present invention. As an example, only one of the up and down control knobs and the left and right control knobs may be provided, and a conventional switch, throttle knob, etc. may be applied to the other control knob. It is also possible to separate the first knob module (30a) and the second knob module (30b) and install them in directions that are easy to operate, such as a right angle direction.

[0050] The above damper member (25) is installed so that after the user rotates the first wheel knob (31a) and the second wheel knob (31b) assembled to the damper shaft (26), the first wheel knob (31a) and the second wheel knob (31b) are not rotated abruptly but are slowly restored to their original state by the elastic force of the spring member. An air damper or an oil damper, etc. can be applied, and since this damper configuration is already a generally known technical content, a detailed description thereof will be omitted.

[0051] The first knob module (30a) is arranged in a first assembly space (S1) separated by a damper bracket (20) and has a configuration in which the first wheel knob (31a) supported by the signal body insertion shaft (38) and the damper shaft (26) rotates, and the spring pressure pin (13) of the base side plate (12) compresses the first spring member (40a) assembled to the first spring insertion portion (35a).

[0052] In addition, the second knob module (30b) is arranged in the second assembly space (S2) and has a configuration in which the second wheel knob (31b) supported by the signal insertion shaft (38) and the damper shaft (26) rotates, causing the spring pressure pin (13) of the base side plate (12) to compress the second spring member (40b) assembled to the second spring insertion portion (35b).

[0053] To explain this in more detail, the first knob module (30a) may be configured to include a first wheel knob (31a) that is directly rotated by a user, a first spring member (40a) that is compressed by the rotation of the first wheel knob (31a) and subsequently rotates the wheel knobs (30a, 30b) back to their original position, and a first knob case (50a) that is molded from a soft material such as rubber or silicone and surrounds the first wheel knob (31a).

[0054] The above first wheel knob (31a) has an overall circular shape and is placed in the first assembly space (S1), has a shape on the front that allows the user to easily rotate it with their fingers, and has a damper case fitting groove (33) and a damper shaft fitting groove (34) provided on the inside of a protruding knob friction portion (32) on one side, and has a first spring insertion portion (35a) in the shape of an "Ω" and a signal body fitting shaft (38) coupled to a signal body member (15) formed on the other side.

[0055] In addition, in the first spring insertion portion (35a), the spring pressure pin (13) of the base side plate (12) is placed in the center, and the first spring members (40a) are inserted on both sides based on the spring pressure pin (13).

[0056] That is, as shown in FIG. 6, the first spring insertion portion (35a) of the first wheel knob (31a) is provided with a spring insertion space having a rotation angle of 90 to 130 degrees at the upper portion with respect to the spring pressing pin (13) and a rib pressing piece (36) at the front end, and a spring insertion space having a rotation angle of 180 to 220 degrees at the lower portion and a rib pressing piece (36) at the front end, so that when the first spring member (40a) is assembled into each spring insertion space, the rib pressing piece (36) rotates with the rotation of the first wheel knob (31a) and the first spring member (40a) is compressed in the direction of the spring pressing pin (13).

[0057] The above first wheel knob (31a) is mainly used to control the up and down movement of the endoscope using the thumb, so that the rotation angle in the upper direction is formed to be smaller than the rotation angle in the lower direction. Even when the rotation angles in the upper and lower directions are the same, it is included in the present invention.

[0058] In addition, the first knob case (50a) is formed of a soft material such as rubber or silicone and is assembled to surround the first wheel knob (31a), and a part of the front of the first wheel knob (31a) is exposed through an open portion (51) on the front so that the user can operate it, and the locking sealing portion (52) on the side is configured to be assembled with the knob friction portion (32).

[0059] Here, a packing fitting groove (32a) is formed in the knob friction portion (32) of the first wheel knob (31a), and a packing portion (52a) is formed in the locking sealing portion (52) of the first knob case (50a), so that the packing portion (52a) and the packing fitting groove (32a) are assembled in a protruding manner, thereby preventing water leakage through the gap between the locking sealing portion (52) and the knob friction portion (32) during the washing and sterilization work of the first wheel knob (31a).

[0060] In addition, the second knob module (30b) may be configured to include a second wheel knob (31b) that is directly rotated by the user, a second spring member (40b) that is compressed by the rotation of the second wheel knob (31b) and subsequently rotates the wheel knobs (30a, 30b) back to their original position, and a second knob case (50b) that is molded from a soft material such as rubber or silicone and surrounds the second wheel knob (31b).

[0061] In addition, the second wheel knob (31b) has an overall circular shape and is placed in the second assembly space (S2), has a shape on the front that allows the user to easily rotate it with their fingers, and has a second spring insertion portion (35b) in the shape of an “Ω” and a signal body fitting shaft (38) coupled to the signal body member (15) provided on the protruding knob friction portion (32) on one side, and a damper case fitting groove (33) and a damper shaft fitting groove (34) are formed on the other side.

[0062] In addition, in the second spring insertion portion (35b), the spring pressure pin (13) of the base side plate (12) is placed in the center, and second spring members (40b) are inserted on both sides based on the spring pressure pin (13).

[0063] That is, as shown in Fig. 7, the second spring insertion portion (35b) of the second wheel knob (31b) is provided with a spring insertion space having a rotation angle of 110 to 170 degrees at the upper and lower portions based on the spring pressing pin (13) and a rib pressing piece (36) at the tip, so that when the second spring member (40b) is assembled into each spring insertion space, the rib pressing piece (36) rotates with the rotation of the second wheel knob (31b) and the second spring member (40b) is compressed in the direction of the spring pressing pin (13).

[0064] The second wheel knob (31b) is formed so that the rotation angles in the upper and lower directions are the same because the left and right movement of the endoscope is mainly controlled using the thumb. Even when the rotation angles in the upper and lower directions are formed differently, it is included in the present invention, and it is preferable to make the diameter of the second wheel knob (31b) larger than that of the first wheel knob (31a) to make a difference so that the user can easily control the endoscope without having to recognize it visually.

[0065] Here, the present invention also includes a method in which a spring fixing projection is further formed at the tip of the first spring insertion portion (35a) and the second spring insertion portion (35b) into which one end of the inserted spring member is fitted, and a spring fitting projection is protruded and formed on both sides of the spring pressure pin (13) to fit into the inner diameter of the spring member, thereby preventing the spring member from being unintentionally separated from the first spring insertion portion (35a) and the second spring insertion portion (35b) during the compression and restoration movement of the spring member.

[0066] In addition, the second knob case (50b) is formed of a soft material such as rubber or silicone and is assembled to surround the second wheel knob (31b), such that a part of the front of the second wheel knob (31b) is exposed through an open portion (51) on the front so that the user can operate it, and the locking sealing portion (52) on the side is configured to be assembled with the knob friction portion (32) of the second wheel knob (31b).

[0067] Here, a packing fitting groove is formed in the knob friction portion (32) of the second wheel knob (31b), and a packing portion is formed in the locking sealing portion (52) of the second knob case (50b), so that the packing portion and the packing fitting groove are assembled in a protruding manner, thereby preventing water leakage through the gap between the locking sealing portion (52) and the knob friction portion (32) during the washing and sterilization work of the second wheel knob (31b).

[0068] FIG. 8 is a perspective view of a rotation locking module, which is a component of the present invention, FIG. 9 is a drawing showing a rotation locking module, which is a component of the present invention, being installed in a control body, and FIG. 10 is a drawing of the rotation locking module of FIG. 8 as seen from below.

[0069] A rotation locking module (60) that is fixed to the controller housing (1) and locks or unlocks the rotational movement of the first wheel knob (31a) and the second wheel knob (31b) by operating the knob fixing switch (62) provided on the upper portion of the first knob module (30a) and the second knob module (30b) may be further installed.

[0070] The above-mentioned rotary locking module (60) can be largely configured to include a fixed holder (61) that is fixedly connected to a main frame (200) placed inside a controller housing (1) or fixedly connected to a base connecting plate (11) of a signal body base (10), a knob fixing switch (62) provided on the upper portion of a rotating body (63) that rotates and moves in an up and down direction inside the fixed holder (61), and a locking member (64) provided on the lower portion of the rotating body (63).

[0071] At this time, at least one O-ring member is provided on the outer periphery of the knob fixing switch (62) to be airtightly assembled on the inner surface of the button assembly hole of the controller housing (1), thereby preventing water from leaking into the inside of the controller housing (1) during the washing and sterilization work of the controller housing (1).

[0072] The above fixed holder (61) can be fixedly connected to the holder bracket (210) by being spaced apart from each other on the upper portions of the first knob module (30a) and the second knob module (30b), and the holder bracket (210) can be connected to the main frame (200) of the control body (300) in such a manner that the rotation locking module (60) can be installed on the control body (300).

[0073] A locking member (64) is provided at the lower portion of the above-mentioned rotating body (63), and when the rotating body (63) moves downward, it comes into surface contact with the locking sealing portion (52) and presses in the direction of the knob friction portion (32), thereby locking the wheel knob (30a, 30b). According to another embodiment, the locking member (64) may come into contact with a component other than the locking sealing portion (52) of the knob device (100) to lock the wheel knob (30a, 30b).

[0074] According to an embodiment, the first knob module (30a) described above may have a structure in which the first knob case (50a) surrounding the first wheel knob (31a) is omitted and only the first wheel knob is disposed. In this case, the locking member (64) can make direct surface contact with the knob friction portion (32) formed on the first wheel knob (31a) to lock the wheel knob. The same applies to the second knob module (30b).

[0075] An endoscope control body (300) according to one embodiment of the present invention may include the knob device (100) of the above-described embodiment. That is, an endoscope control body (300) in which a knob module including a wheel knob (31a, 31b) according to the present embodiment is installed may include a rotation locking module (60) to fix the wheel knob (31a, 31b) in a locked state.

[0076] The rotation locking module (60) may be configured to keep the wheel knob (30a, 30b) in a locked state. Here, locking the wheel knob (30a, 30b) may mean fixing the wheel knob (30a, 30b) so that it cannot move.

[0077] According to an embodiment, the rotary locking module (60) includes: a knob fixing switch (62) that is exposed to the outside so that a user can grip it; a rotating body (63) that is connected to the knob fixing switch (62) and rotates together with the rotation of the knob fixing switch (62); a fixed holder (61) that rotatably holds the rotating body (63); and

[0078] It can be configured to include a locking member (64) that moves up and down by the rotation of the rotating body (63) to lock or release the wheel knob (30a, 30b) in a locked state.

[0079] The knob fixing switch (62) may refer to a portion exposed to the outside of the endoscope control body (300) in the rotation locking module (60) according to the present embodiment. The user can operate the rotation locking module (60) by holding the knob fixing switch (62) and turning it clockwise or counterclockwise. The user can hold the knob fixing switch (62) and turn it to one side to lock the wheel knob (30a, 30b) or turn it to the other side to unlock it.

[0080] The rotating body (63) may be configured to be connected to the knob fixing switch (62) and rotate together with the knob fixing switch (62). The rotating body (63) is installed to be able to rotate about an axis by the fixed holder (61) and can rotate clockwise or counterclockwise within a certain range. The rotating body (63) may be formed in a cylindrical shape according to an embodiment, and may be installed inside the fixed holder (61) and operate in a manner of rotating about an axis with respect to the fixed holder (61).

[0081] The fixed holder (61) can have the function of rotatably holding the rotating body (63). The fixed holder (61) can be fixedly installed on the holder bracket (210) located on one side of the base connecting plate (11) in the above-described embodiment. According to the embodiment, the holder bracket (210) can be installed on the base connecting plate. In addition, according to the embodiment, the holder bracket (210) can be installed on the main frame (200) installed inside the control body (300). According to the embodiment, the fixed holder (61) can be installed on a component other than the base connecting plate (11), that is, on any part of the internal component of the control body (300).

[0082] The holder bracket (210) performs the function of fixing the rotation locking module (60) inside the control body (300). The holder bracket (210) may be configured to include a module fixing part (220) that fixes the rotation locking module (60) and a fixing installation part (230) that is fixed to the control body (300). The module fixing part (220) may be a part where the rotation locking module (60) is seated and fixed. The fixing installation part (230) may be configured to be installed in the main frame (200) installed inside the control body (300) according to an embodiment.

[0083] The module fixing part (220) can be formed in a protruding shape including a convex portion (221) and a concave portion (222). The convex portion (221) of the module fixing part (220) toward the rotation locking module (60) can be connected to the fastening portion (61a) of the fixing holder (61) with a bolt, and when the fixing holder (61) is formed in a cylindrical shape, the module mounting part (223) that comes into contact with the circumference of the fixing holder (61) is formed in a shape corresponding to the circumference of the fixing holder (61) so that the fixing holder (61) can be mounted and fixed. A concave portion (222) is formed between the protruding and protruding convex portions (221), and an empty space (240) is formed in the concave portion (222) so that the cylindrical fixing holder (61) has the empty space (240) and is fixedly installed on the module mounting part (223).

[0084] The rotation locking module (60) can be efficiently installed inside the control body (300) by configuring the holder bracket (210).

[0085] The configuration of the rotary locking module (60) will be described. A first coupling portion (65) may be formed on the circumference of the rotating body (63), and a second coupling portion (66) may be formed on one side of the fixed holder (61). The first coupling portion (65) and the second coupling portion (66) may have a structure that allows them to be coupled to each other. According to an embodiment, the first coupling portion (65) may include a protrusion (65), and the second coupling portion (66) may be a path setting portion (66).

[0086] The path setting portion (66) can form a movement path of the protrusion (65) in the fixed holder (61). The protrusion (65) can move through the path formed in the path setting portion (66). Depending on the embodiment, the path setting portion (66) can be a groove or a penetration portion that accommodates the protrusion (65).

[0087] The rotating body (63) is inserted into the fixed holder (61) and can rotate about an axis inside the fixed holder (61). The fixed holder (61) has an inner surface corresponding to the cylindrical outer surface of the rotating body (63), and the cylindrical outer surface may rotate by contacting the inner surface.

[0088] The path setting portion (66) may be formed with a constant slope and may have one end (66a) and the other end (66b). The protrusion (65) may move between one end (66a) and the other end (66b) of the path setting portion (66). According to an embodiment, an anti-slip portion (66d) may be provided to prevent the protrusion (65) from being pushed back after it is completely seated on one end (66a) and / or the other end (66b) of the path setting portion (66).

[0089] The anti-slip portion (66d) may include a protruding shape formed at one end (66a) and the other end (66b) of the path setting portion (66) according to the embodiment.

[0090] In order to couple the rotating body (63) and the fixed holder (61), an inlet portion (66c) may be formed on the upper surface among the upper and lower surfaces of the cylindrical body of the fixed holder (61), and the inlet portion (66c) may be connected to one end (66a) of the path setting portion (66). With this structure, when manufacturing the rotation locking module (60), the protrusion (65) of the rotating body (63) may be seated on the path setting portion (66) through the inlet portion (66c) of the fixed holder (61).

[0091] One end (66a) of the path setting part (66) can be positioned higher toward the upper surface of the cylindrical body of the fixed holder (61), and the other end (66b) can be positioned lower toward the lower surface of the cylindrical body of the fixed holder (61). That is, the path setting part (66) can be formed to have an incline at the fixed holder (61). The protrusion (65) of the rotating body (63) can be positioned at one end (66a) of the path setting part (66) and then move along the path to the other end (66b) to push the rotating body (63) toward the lower surface. The rotating body (63) can press the locking member (64) while being pushed down, thereby causing the locking member (64) to move linearly downward.

[0092] The locking member (64) can have the function of locking and fixing the wheel knob (30a, 30b). The rotating body (63) and the locking member (64) are mutually coupled and move up and down together. The rotating body (63) moves up and down by rotation, and the locking member (64) can move up and down regardless of the rotation of the rotating body (63).

[0093] According to an embodiment, a bearing member (67) may be installed between the rotating body (63) and the locking member (64). The bearing member (67) may include a hollow cylindrical shape according to an embodiment.

[0094] According to an embodiment, a bearing mounting portion may be formed on one side of a rotating body (63), a bearing member (67) may be press-fitted into the bearing mounting portion, and a shaft portion (64a) may be formed on one side of a locking member (64) so ​​as to be press-fitted into the bearing. The shaft portion (64a) of the locking member (64) may be press-fitted into a groove portion formed in the center of the bearing member (67). The rotating body (63) and the locking member (64) may be relatively rotated by the bearing member (67). That is, the locking member (64) may be axially rotatable when its shaft portion (64a) is inserted into the bearing member (67). As a result, when the locking member (64) is pressed while the rotating body (63) rotates by the bearing member (67), the locking member (64) does not rotate together with the rotating body (63) but only moves up and down even when the rotating body (63) rotates axially.

[0095] In the present invention, a rotation-prevention member (70) that guides only the up-and-down movement of the locking member (64) while preventing the rotation of the locking member (64) may be provided. According to an embodiment, the rotation-prevention member (70) may be formed to extend in the same direction as the locking member (64) from one side of the fixed holder (61).

[0096] The rotation-preventing portion (70) may be formed as a pair and arranged on both sides of the locking member (64). The pair of rotation-preventing portions (70) may have a shape that wraps around both sides of the locking member (64), respectively. A catch portion (71) that wraps around and holds the locking member (64) may be formed at the ends of the pair of rotation-preventing portions (70). Depending on the embodiment, the catch portion (71) may have an ‘ㄱ’ shape in cross-section, and since the pair of catch portions (71) are arranged to wrap around only the front and both sides among the front, rear, and both sides of the locking member (64), the locking member (64) cannot rotate in either the clockwise or counterclockwise direction. That is, depending on the embodiment, the pair of catch portions (71) may be formed to wrap around only one side among one side and the other side of the locking member (64). By this structure, even if the rotating body (63) rotates, the locking member (64) does not rotate, and a bearing member (67) is interposed between the rotating body (63) and the locking member (64), so that only the rotating body (63) rotates, and the locking member (64) is restrained by the rotation restraining member (70) and does not rotate.

[0097] As a result, when the rotating body (63) rotates and moves up and down, the locking member (64) can move up and down together with the rotating body (63).

[0098] A stopper (80) may be formed on one side of the locking member (64) to prevent the rotating body (63) from being removed by coming into contact with the end of the rotation-preventing member (70). Here, the stopper (80) may be a protrusion protruding from one side of the locking member (64) depending on the embodiment. When manufacturing the rotation locking module (60), the rotating body (63) may be inserted from the upper part of the fixed holder (61), and the locking member (64) may be inserted from the lower part of the fixed holder (61) so that the rotating body (63) and the locking member (64) are coupled through the bearing member (67). In this case, the rotating body (63) and the locking member (64) are coupled in a state where the stopper (80) of the locking member (64) is aligned with the rotation-preventing member (70).

[0099] Since the locking member (64) is guided in its up and down movement by the rotation-prevention member (70) including the catch (71) and its axial rotation is prevented, there is no need for a separate guide configuration for linear reciprocating movement, so it is easy to install the rotation locking module (60) in the control body (300), which is economical during manufacturing. That is, since the locking member (64) is guided and prevented from rotating by the rotation-prevention member (70) extending from the fixed holder (61), the rotation locking module (60) can be fixedly installed inside the control body (300) by the holder bracket (210), and does not require a separate configuration to assist the operation of the rotation locking module (60).

[0100] When manufacturing a rotary locking module (60), the manufacturer can connect the rotary body (63) and the fixed holder (61) by having the protrusion (65) of the rotary body (63) ride into the inlet portion (66c) formed on the upper surface of the cylindrical body of the fixed holder (61). In this case, since the end of the inlet portion (66c) is connected to one end (66a) of the path setting portion (66), the rotary body (63) can be removed by falling upward when its protrusion (65) is located at the end of the inlet portion (66c). In order to prevent the rotating body (63) from being unintentionally removed from the fixed holder (61), a rotation-preventing portion (70) is formed to extend to a certain length on one side of the fixed holder (61), and at the same time, a stopper (80) is formed at a position opposite to the end of the rotation-preventing portion (70) of the locking member (64), so that even if the protrusion (65) of the rotating body (63) is located at the end of the inlet portion (66c), the rotating body (63) can be prevented from being removed by falling upward.

[0101] The operating method of the rotation locking module (60) is explained. When the user rotates the knob fixing switch (62), the rotating body (63) descends and the locking member (64) presses the locking sealing part (52) toward the knob friction part (32) or presses the knob friction part (32) to prevent the rotation of the first wheel knob (31a) or the second wheel knob (31b), and the protrusion (65) that moves along the path setting part (66) provided on one side of the fixed holder (61) is caught by the anti-push part (66d) formed at the end of the path setting part (66), so that the locking member (64) is locked in a lowered state.

[0102] Accordingly, the locking sealing portions (52) of the first knob case (50a) and the second knob case (50b) assembled with the knob friction portions (32) of the first wheel knob (31a) and the second wheel knob (31b) are configured to come into surface contact with the locking member (64) that moves downward by the rotational operation of the rotational locking module (60) provided on the upper surface of the controller housing (1), thereby fixing the first wheel knob (31a) and the second wheel knob (31b) in a locked state, and by rotating the rotational locking module (60) again to move the locking member (64) back to its original position, the locked state of the first wheel knob (31a) and the second wheel knob (31b) can be easily released and used.

[0103] Or, in a structure where the first knob case (50a) and the second knob case (50b) are omitted, the knob friction portions (32) of the first wheel knob (31a) and the second wheel knob (31b) are configured to be fixed in a locked state by making surface contact with the locking member (64) that moves downward by the rotational operation of the rotational locking module (60) provided on the upper surface of the controller housing (1), and the rotational locking module (60) is rotated again to return the locking member (64) to its original position, so that the locked state of the first wheel knob (31a) and the second wheel knob (31b) can be easily released and used.

[0104] Any use of examples or exemplary terms (e.g., "etc.") in the present invention is merely intended to illustrate the invention in detail and is not intended to limit the scope of the invention, unless otherwise defined by the claims. Furthermore, those skilled in the art will appreciate that various modifications, combinations, and variations can be made, depending on design conditions and factors, within the scope of the appended claims or their equivalents.

[0105] Therefore, the idea of ​​the present invention should not be limited to the embodiments described above, and not only the scope of the patent claims described below but also all scopes equivalent to or equivalently modified from the scope of the patent claims are considered to fall within the scope of the idea of ​​the present invention.
