Description

Medical lighting device

[0001] The present invention relates to a medical lighting device.

[0002] Generally, headlamps are used attached to headbands, hats, or helmets in fields such as mining, medicine, and surgery.

[0003] These headlamps have the advantage of allowing the user wearing them to illuminate their actual field of vision without the need for a fixed floodlight or a portable lamp.

[0004] In particular, among headlamps, there are headlamps equipped with multiple light sources to achieve a shadowless effect without obstructing the user's field of vision.

[0005] However, in conventional headlamps, the light source unit connected to the frame is fixed, so the angle of each light source cannot be adjusted, and the light source unit is provided as a single assembly.

[0006] The embodiments of the present invention aim to provide a medical lighting device that facilitates easy visualization of the user, allows for angle adjustment of the light source, and enables disassembly and assembly of the lamp module.

[0007] In addition, the purpose is to provide a medical lighting device capable of providing an enlarged upright image of an object along with illumination of the object, and capable of simultaneously adjusting the angles of the light source and the magnifying glass.

[0008] However, these tasks are exemplary and do not limit the scope of the invention.

[0009] One embodiment of the present invention provides a medical lighting device comprising a main body frame mounted on the head of a user, a main body arm rotatably disposed at a front end of the main body frame, a light source unit disposed on the main body arm, and a loupe unit having a pair of magnifying glasses mounted on the main body arm and disposed in front of both eyes of the user.

[0010] The medical lighting device according to the embodiments of the present invention allows for easy visualization of the user, enables adjustment of the angle of the light source, and allows for disassembly and assembly of the lamp module.

[0011] In addition, the medical lighting device according to the embodiments of the present invention can provide an enlarged upright image of an object along with illumination of the object, and can simultaneously perform angle adjustment of the light source and the magnifying glass, thereby improving workability and convenience.

[0042] FIG. 1 is a perspective view illustrating a medical lighting device according to an embodiment of the present invention, FIG. 2 is a perspective view illustrating an example of angle adjustment of the lamp module of FIG. 1, and FIG. 3 is an exploded perspective view of the lamp module of FIG. 1. FIG. 4 is a perspective view illustrating a loupe unit of FIG. 1, and FIG. 5 is an exploded perspective view of FIG. 4.

[0043] Referring to FIG. 1, a medical lighting device (10) according to one embodiment of the present invention can improve the user's wearing comfort by easily adjusting the length of each component, can secure the user's field of vision by providing a light source unit (130), and can perform precision work such as surgery more easily and conveniently by providing a magnified image of a small object by providing a loupe unit (140).

[0044] More specifically, a medical lighting device (10) according to one embodiment of the present invention may include a main body frame (110), a main body arm (120), a light source unit (130), and a loupe unit (140).

[0045] The main body frame (110) is a frame that is mounted and fixed to the user's head and may include a main frame (111), a front frame (112), a rear frame (113), a forehead support (114), and a occipital support (115).

[0046] Specifically, the main frame (111) may be formed in a curved shape to cover the front and upper surfaces of the user's head, and a front frame (112) and a rear frame (113) may be connected to the front and rear, respectively.

[0047] In the main frame (111) of the present embodiment, a length adjustment unit (116) for length adjustment may be provided, and as an example, the length adjustment unit (116) may be operated as a toggle switch.

[0048] That is, the main frame (111) can be moved forward relative to the rear frame (113) by operating a toggle switch to increase its length, or moved backward to return to its original length.

[0049] Additionally, the main frame (111) can be fixed in a length-adjusted state, and various mechanical configurations can be applied as a length adjustment mechanism.

[0050] The front frame (112) of the present embodiment may be extended from the front end of the main frame (111) and may be combined with the main body arm (120) to be described later, so that the light source unit (130) and the loupe unit (140) can be supported via the main body arm (120).

[0051] The rear frame (113) of the present embodiment can be formed to cover the rear of the user's head and can perform the role of supporting the entire rear of the user's head by combining with the occipital support (115) described later.

[0052] At this time, the rear frame (113) may be further equipped with a laryngeal support (117) in addition to the laryngeal support (115). The laryngeal support (117) can be used to support the user's larynx more stably.

[0053] The rear frame (113) may be formed as a separate member from the main frame (111) and joined, but is not limited thereto, and at least a part of the rear frame (113) may be formed as one body with the main frame (111).

[0054] The forehead support (114) of the present embodiment can be positioned on the front inner side of the main frame (111) to correspond to the user's forehead, and accordingly can perform the role of supporting the user's forehead.

[0055] The forehead support (114) can be formed to be movable along the vertical direction (Z-axis direction) relative to the main frame (111).

[0056] For example, the support member (114) is already positioned to be retractable and / or retractable from the main frame (111) so that its position can be adjusted to fit the user's forehead. At this time, various mechanical mechanisms for adjusting the position of the forehead support member (114) may be applied.

[0057] The laryngeal support (115) of the present embodiment is coupled to the rear end of the rear frame (113) and can support the entire rear of the user's head together with the rear frame (113).

[0058] The larynx support (115) can be positioned to be movable along the vertical direction (Z-axis direction) relative to the rear frame (113).

[0059] That is, the larynx support (115) is positioned to be retractable and / or retractable from the rear frame (113) so that its position can be adjusted to fit the user's larynx. At this time, various mechanical mechanisms for adjusting the position of the larynx support (115) may be applied.

[0060] Additionally, although not described in detail, a power supply unit (not shown) for operating the light source unit (130) described later may be provided within the head support unit (115), but is not limited thereto, and the power supply unit may be built into the light source unit (130).

[0061] Referring to FIGS. 1 to 3, the main body arm (120) can be rotatably positioned along the vertical direction (Z-axis direction) at the front end of the main body frame (110).

[0062] Specifically, a frame connection part (120a) may be formed on the upper part of the main body arm (120), and a hinge part (112a) may be formed on the lower part of the front frame (112).

[0063] Accordingly, the frame connecting portion (120a) of the main body arm (120) is axially connected to the hinge portion (112a) of the front frame (112), so that the main body arm (120) can be rotated in the up and down direction (Z-axis direction) with respect to the axial connection portion with the front frame (112).

[0064] Meanwhile, a light source unit (130) and a loupe unit (140), which will be described later, can be mounted on the main body arm (120), and as a result, the light source unit (130) and the loupe unit (140) can rotate together with the main body arm (120).

[0065] Specifically, the main body arm (120) may be spaced apart from each other along the longitudinal direction, that is, the vertical direction (Z-axis direction), to form a first lamp installation part (121) and a second lamp installation part (122).

[0066] At this time, the light source unit (130) described below may include a first lamp module (131) and a second lamp module (132), wherein the first lamp module (131) may be mounted on the first lamp installation unit (121) and the second lamp module (132) may be mounted on the second lamp installation unit (122).

[0067] Additionally, a loupe installation part (123) may be formed between the first lamp installation part (121) and the second lamp installation part (122) of the main body arm (120).

[0068] The loupe installation part (123) can connect the first lamp installation part (121) and the second lamp installation part (122), and the loupe unit (140) described later can be detachably mounted on the loupe installation part (123).

[0069] For example, the loupe mounting part (123) may be formed as a ladder structure including a plurality of locking holes (123a) formed along the vertical direction (Z-axis direction) of the main body arm (120), and a plurality of locking protrusions (144a) of the loupe unit (140) described later may be detachably connected to the plurality of locking holes (123a).

[0070] That is, a plurality of locking protrusions (144a) can be pressed into a plurality of locking holes (123a) to mount a loupe unit (140) on a loupe installation part (123), and when the plurality of locking protrusions (144a) are released from the plurality of locking holes (123a), the loupe unit (140) can be separated from the loupe installation part (123).

[0071] As described above, a medical lighting device (10) according to one embodiment of the present invention is equipped with two or more lamp modules (131, 132) as light source units (130) in a main body arm (120), so that two light sources can be concentrated to illuminate the area where the light source is irradiated, that is, the user's intended field of vision, and thus can be used as a shadowless lamp that does not create shadows.

[0072] In addition, a medical lighting device (10) according to one embodiment of the present invention can smoothly perform precision work such as surgery by providing a magnified image of a small object to the user by mounting a loupe unit (140) on the main body arm (120).

[0073] Meanwhile, the light source unit (130) and the loupe unit (140) mounted on the main body arm (120) can be rotated along the vertical direction (Z-axis direction) to face the desired target view of the user.

[0074] For example, the light source unit (130) and the loupe unit (140) can be rotated together with the main body arm (120) as the main body arm (120) rotates in the up and down direction (Z-axis direction) with respect to the axis coupling portion of the front frame (112).

[0075] At this time, a handle (120b) for operation may be formed at the lower end of the main body arm (120) in the longitudinal direction (Z-axis direction), and the user can rotate the light source unit (130) and the loupe unit (140) together with the main body arm (120) in the vertical direction (Z-axis direction) by operating the handle (120b) in the vertical direction (Z-axis direction).

[0076] That is, even during work and surgery, the handle (120b) of the main body arm (120) can be operated to easily adjust the relative angle and position of the light source unit (130) and the loupe unit (140) with respect to the front frame (112).

[0077] As another example, the light source unit (130) and the loupe unit (140) can each be rotated individually along the vertical direction (Z-axis direction) independently of the rotation of the main body arm (120). This will be described later.

[0078] As described above, the light source unit (130) may include a first lamp module (131) and a second lamp module (132) positioned above and below the loupe installation unit (120) along the length direction (Z-axis direction) of the main body arm (120).

[0079] In this embodiment, the first lamp module (131) and the second lamp module (132) may be lamp modules with different structures, but for convenience of explanation, lamp modules with the same structure are exemplified, and accordingly, the description of the second lamp module (132) is replaced by the description of the first lamp module (131).

[0080] Referring to FIGS. 2 and 3, the first lamp module (131) can irradiate light toward a subject and can utilize various source devices capable of generating light. For example, the first lamp module (131) may be an LED that irradiates light of a specific wavelength band.

[0081] Specifically, the first lamp module (131) may include a light source (1311), a fixed link portion (1312), a light transmission portion (1313), a light cover (1314), and a light filter (1315).

[0082] The light source (1311) may be an LED placed inside the first lamp installation part (121) of the main body arm (120), and may be combined with a heat sink (1311a) for dissipating heat generated during light emission.

[0083] At this time, the light source (1311) can be mounted at the rear of the fixed link portion (1312), and the light emitted from the light source (1311) can be directed forward through an opening hole formed in the center of the fixed link portion (1312).

[0084] The fixed link portion (1312) can be rotatably positioned on the first lamp installation portion (121), and for this purpose, insertion link members (1316) can be positioned on both sides of the fixed link portion (1312).

[0085] At this time, a first toothed portion (121a) may be formed on both inner sides of the first lamp installation portion (121), and a second toothed portion (1316a) that engages with the first toothed portion (121a) may be formed on both outer sides of the insertion link member (1316).

[0086] That is, when a force greater than a certain amount is applied while the first tooth part (121a) and the second tooth part (1316a) are engaged with each other, slip occurs, and the second tooth part (1316a) can rotate in an alternating manner relative to the first tooth part (121a).

[0087] Here, a coupling member (1317) is disposed on at least one side of the first lamp installation part (121) so that the position of the fixed link part (1312) on the first lamp installation part (121) can be fixed or released so that the fixed link part (1312) can rotate.

[0088] At this time, the connecting member (1317) can be connected to the insertion link member (1316) and the rotational center axis through the connecting hole (121b) formed in the first lamp installation part (121).

[0089] Accordingly, the fixed link portion (1312) can be rotated in the up-and-down direction (Z-axis direction) on the first lamp installation portion (121) through the interaction of the first tooth portion (121a) and the second tooth portion (1316a), and can be fixed in the rotated position through the coupling member (1317).

[0090] That is, the first lamp module (131) can be rotated individually along the vertical direction (Z-axis direction) independently of the rotation of the main body arm (120), and can be stably fixed in the rotated position.

[0091] The light-transmitting portion (1313) may include a reflector (1313a), a fixing ring (1313b), and a cover glass (1313c), and may be assembled by being received in the fixing link portion (1312) and the light cover (1314).

[0092] Accordingly, light emitted from the light source (1311) can pass through the reflector (1313a) and cover glass (1313c) and be irradiated forward.

[0093] The light cover (1314) can be assembled on both sides of the fixed link portion (1312) and can be assembled with the fixed link portion (1312) to cover the light source (1311) and the light transmission portion (1313).

[0094] A light filter (1315) may be assembled in front of the light cover (1314), and the light filter (1315) may filter the light emitted from the light source (1311) and transmitted through the light transmission part (1313), thereby allowing light in the wavelength range desired by the user to be irradiated.

[0095] Referring to FIGS. 1, 4, and 5, the loupe unit (140) can be detachably mounted on the main body arm (120) to provide a magnified image to the user, thereby allowing work and surgery to be performed more easily and precisely.

[0096] Specifically, the loupe unit (140) may include a magnifying glass (141), a loupe frame (142), a link arm (143), and a mounting part (144).

[0097] First, the magnifying glass (141) can be positioned as a pair on both the left and right sides along the horizontal length direction (X-axis direction) of the loupe frame (142), and when the loupe unit (140) is mounted on the main body arm (120), it can be positioned in front of both eyes of the user.

[0098] Each magnifying glass (141) may include a frame connecting part (1411), an eyepiece (1412), a fixed barrel (1413), a cam barrel (1414), an objective lens (1415), and a moving barrel (1416).

[0099] The frame connecting part (1411) can be connected and supported by the remaining components of the magnifying glass (141) and can be detachably mounted to the loupe frame (142).

[0100] At this time, a position adjustment unit is interposed between the loupe frame (142) and each magnifying glass (141) to guide the left and right movement (X-axis direction) of each magnifying glass (141) on the loupe frame (142) and to fix each magnifying glass (141) at the moved position.

[0101] For example, the position adjustment unit may include a guide hole (142a) formed along the left-right direction (X-axis direction) of the loupe frame (142), and a fastening member (1418) having one end penetrating the guide hole (142a) and coupled to the frame coupling part (1411) of the magnifying glass (141).

[0102] That is, the frame connecting part (1411) can be reciprocated along the guide hole (142a) while connected to the fastening member (1418) at the bottom of the guide hole (142a) of the loupe frame (142), and when the movement is completed, it can be fixed in close contact with the loupe frame (142) by continuing to be connected to the fastening member (1418).

[0103] Ultimately, the magnifying glass (141) including the frame connecting part (1411) can be individually moved on the loupe frame (142) to fit each user's two eyes and can be stably fixed in the moved state.

[0104] Additionally, the frame connecting part (1411) can rotate on its own axis around the vertical axis (Z-axis) while connected to the connecting member (1418), and accordingly, the magnifying glass (141) can also rotate on its own axis around the vertical axis (Z) to adjust the viewing angle more diversely.

[0105] The eyepiece (1412) is a lens that the user places their eye against to observe an object, and the objective lens (1415) is a lens that collects light from the object and focuses it to form an image of the object together with the user's eye.

[0106] The fixed barrel (1413) may have an eyepiece (1411) built into it, and its rear side may be fixed by being connected to the frame connecting part (1411).

[0107] The cam barrel (1414) can be coupled to and fixed to the front side of the fixed barrel (1413), and a plurality of cam holes (1414a) can be formed in a spiral shape on its circumferential surface. At this time, the moving barrel (1416) can be moved in the forward and backward direction (Y-axis direction) during forward and reverse rotation through the plurality of cam holes (1414a).

[0108] The objective lens (1415) is a lens corresponding to the object side, and is a lens for collecting light from the object and focusing it to form an image of the object on the eyepiece lens (1412), and can be arranged in multiple numbers inside the moving barrel (1416) to form an effective enlarged image.

[0109] The moving barrel (1416) can be positioned to surround the cam barrel (1414), and as described above, the moving barrel (1416) can be moved in the forward and backward direction (Y-axis direction) when the cam barrel (1414) is fixed and rotates in the forward and reverse direction.

[0110] For example, a fitting hole (1416a) may be formed in the moving barrel (1416), and a coupling pin (1419) may be fitted into the fitting hole (1416a). With the coupling pin (1419) fitted into the fitting hole (1416a), the end of the coupling pin (1419) may protrude inwardly into the moving barrel (1416) and be inserted into the cam hole (1414a).

[0111] Accordingly, when the moving barrel (1416) is rotated forward and reverse, the connecting pin (1419) moves in a spiral shape along the cam hole (1414a), and the moving barrel (1416) can reciprocate in the forward and backward directions relative to the fixed cam barrel (1414).

[0112] In this way, when the moving barrel (1416) is reciprocated in the forward and backward direction (Y-axis direction) relative to the cam barrel (1414), that is, the fixed barrel (1413), the distance between the eyepiece (1412) fixed to the fixed barrel (1413) and the objective lens (1415) fixed to the moving barrel (1416) can be adjusted. Consequently, by adjusting the distance between the eyepiece (1412) and the objective lens (1415), the image of the object can be accurately focused.

[0113] Next, referring to FIGS. 4 and 5, a pair of magnifying glasses (141) may be arranged on both the left and right sides of the loupe frame (142), and a link arm (143) and a mounting part (144) may be sequentially connected and arranged in the center.

[0114] The loupe frame (142) may be a body having a pair of magnifying glasses (141) arranged on both the left and right sides, and a link arm (143) and a mounting part (144) arranged in the center to support all parts of the loupe unit (140) and adjust the viewing angle of the magnifying glasses (141).

[0115] That is, the loupe frame (142) can adjust the viewing angle of the magnifying glass (141) by rotating together with the link arm (143) when the link arm (143) rotates along the vertical direction (Z-axis direction) while the mounting part (144) is connected to the main body arm (120).

[0116] The link arm (143) can be rotatably positioned along the vertical direction (Z-axis direction) in the center of the loupe frame (142).

[0117] Specifically, the link arm (143) may include a first link arm (1431) and a second link arm (1432). Of course, the link arm (143) may be formed as a single unit, but in this embodiment, it is disclosed that it is composed of multiple units to adjust the rotation angle of the loupe frame (142), i.e., the magnifying glass (141), in various ways.

[0118] One end of the first link arm (1431) can be axially connected to the center of the loupe frame (142) and the other end can be axially connected to one end of the second link arm (1432).

[0119] Additionally, the other end of the second link arm (1432) may be axially coupled with one end of the mounting part (144). Of course, the other end of the second link arm (1432) may not be axially coupled with one end of the mounting part (144), but in this embodiment, it is disclosed that it is axially coupled to allow for various rotation angle adjustments of the second link arm (1432).

[0120] As described above, the link arm (143) of the loupe unit (140) is composed of a plurality of first link arms (1431) and second link arms (1432), and the first link arm (1431) and the second link arm (1432) are each axially coupled to the loupe frame (142) and the mounting part (144), respectively, so that the rotation angle of the magnifying glass (141) of the loupe frame (142) can be adjusted more diversely and conveniently.

[0121] Meanwhile, a plurality of locking projections (144a) may be formed at the other end of the mounting portion (144), and the plurality of locking projections (144a) may have a clamp shape extending upward and downward from the mounting portion (144).

[0122] Although not illustrated in detail, the mounting part (144) can be detachably mounted to the main body arm (120) in various ways, such as a detachable method using magnetic force and a screw fastening method, in addition to a detachable method using a plurality of locking protrusions (144a).

[0123] Ultimately, by having a plurality of locking projections (144a) of the mounting portion (144) detachably coupled to a plurality of locking holes (123a) of the main body arm (120), the mounting portion (144) can be detachably coupled to the loupe installation portion (123) of the main body arm (120). In other words, the loupe unit (140) can be detachably coupled to the main body arm (120).

[0124] Hereinafter, a medical lighting device according to another embodiment of the present invention will be described.

[0125] FIG. 6 is a perspective view illustrating a medical lighting device according to another embodiment of the present invention, FIG. 7 is a perspective view illustrating the main body arm and lamp module of FIG. 6 in disassembled form, and FIG. 8 is a perspective view illustrating the lamp module in FIG. 6 in a rotated state.

[0126] Referring to FIGS. 6 to 8, a medical lighting device (20) according to another embodiment of the present invention may include a main body frame (210), a main body arm (220), a light source unit (230), and a loupe unit (240), similar to the above-described embodiment.

[0127] The medical lighting device (20) of this embodiment will be described with a focus on different configurations, omitting detailed descriptions of configurations applicable in the same way as the medical lighting device (10) of the previously described embodiment.

[0128] The main body frame (210) is a frame that is mounted and fixed to the user's head and may include a main frame (211), a front frame (212), a rear frame (213), a forehead support (214), and a occipital support (215).

[0129] Unlike the previously described embodiment, the main body frame (210) of this embodiment discloses that the forehead support (214) and the occipital support (215) are connected in the form of a band that surrounds the user's head.

[0130] At this time, the rear ends of both sides of the forehead support (214) can be inserted into or withdrawn from the front ends of both sides of the occipital support (215), and the length between them can be adjusted, so that it can be worn to fit the circumference size of the user's head.

[0131] Of course, the main frame (210) of this embodiment, similar to the previously described embodiment, can have its length adjusted relative to the rear frame (213) by operating the main frame (211) as a kind of toggle switch, and thus can be worn according to the front and rear size of the user's head.

[0132] The main body arm (220) of this embodiment may be rotatably positioned in all directions (X-axis direction, Y-axis direction, Z-axis direction) at the lower end of the front frame (212), unlike the previously described embodiment.

[0133] For example, the upper part of the main body arm (220) of the present embodiment is connected to the lower part of the front frame (212) in a ball joint manner, so that the main body arm (220) can be rotated in all directions (X-axis direction, Y-axis direction, Z-axis direction) relative to the front frame (212).

[0134] That is, a ball portion (212a) may be formed protrudingly on the lower part of the front frame (212), and a ball coupling portion (220a) corresponding to the ball portion (212a) may be formed on the upper part of the main body arm (220), and the ball portion (212a) may be fitted into the ball coupling portion (220a) by tightening a screw (not shown) on the ball coupling portion (220a) while the ball portion (212a) is inserted into the inner side of the cut portion of the ball coupling portion (220a).

[0135] Accordingly, when a user applies a certain force to the main body arm (220), the main body arm (220) can be rotated in all directions (X-axis direction, Y-axis direction, Z-axis direction) with respect to the ball portion (212a) of the front frame (212), and when the applied force is removed, the main body arm (220) can be fixed in the rotated state.

[0136] Accordingly, since the main body arm (220) of the present embodiment can be rotated in all directions relative to the front frame (212), the user can rotate the main body arm (220) in all directions (X-axis direction, Y-axis direction, Z-axis direction) to illuminate the light source unit (230) at a wider variety of angles.

[0137] At this time, a handle (220b) may also be formed on the lower part of the main body arm (220) of the present embodiment, and the user can easily adjust the main body arm (220) by operating the handle (220b).

[0138] Also, unlike the previously described embodiment, the main body arm (220) of this embodiment may have a loupe installation part (223) composed of a plurality of link arms (2231, 2232, 2233).

[0139] That is, in the loupe installation part (223) of the present embodiment, each link arm (2231, 2232, 2233) can rotate independently of each other, so the light source part (230) can be rotated at a wider variety of angles.

[0140] For example, when the first lamp module (231) and the second lamp module (232) of the light source unit (230) are respectively positioned in the vertical direction (Z-axis direction) relative to the loupe installation part (223) of the main body arm (220), the second lamp module (232) can be independently rotated at various angles relative to the first lamp module (231) by operating at least one link arm (2231, 2232, 2233).

[0141] Meanwhile, since the light source unit (230) of the present embodiment can be applied in the same way as the light source unit (130) of the previously described embodiment, a detailed description thereof is omitted, but it is not limited thereto, and the light source unit (230) of the present embodiment may be a lamp module of various structures other than the light source unit (130) of the previously described embodiment.

[0142] In addition, since the loupe unit (240) of this embodiment can be applied in the same way as the loupe unit (140) of the previously described embodiment, a detailed description thereof will be omitted.

[0143] However, unlike the loupe unit (140) of the above-described embodiment, the loupe unit (240) of this embodiment has a structure that is detachably coupled to the main body arm (220).

[0144] That is, the mounting portion (244) of the loupe unit (240) of the present embodiment may have a plurality of locking projections (244a) protruding in the horizontal left-right direction (X-axis direction) rather than in the vertical direction (Z-axis direction) of the main body arm (220).

[0145] Accordingly, unlike the previously described embodiment, there is no need to separately form a plurality of catch holes in the loupe installation part (223) of the main body arm (220) of the present embodiment.

[0146] Accordingly, a plurality of locking projections (244a) of the mounting portion (244) can be detachably mounted to any one of the plurality of link arms (2231, 2232, 2233) of the loupe mounting portion (223), and the loupe unit (240) can be detachably mounted to the main body arm (220).

[0147] Although not illustrated in detail, the mounting portion (244) of this embodiment can also be detachably mounted to the main body arm (220) in various ways, such as a detachable method using magnetic force or a screw fastening method, in addition to a detachable method using a plurality of locking projections (244a).

[0148] The medical lighting device (20) according to the present embodiment is also equipped with two or more lamp modules (231, 232) as light source units (230) in the main body arm (220), so that two light sources can be concentrated to illuminate the area where the light source is irradiated, that is, the user's intended field of vision, and thus can be used as a shadowless lamp that does not create shadows.

[0149] In addition, the medical lighting device (20) of the present embodiment also has a loupe unit (240) detachably mounted on the main body arm (220), thereby providing the user with an enlarged image of a small object, which allows for the smooth performance of precision work such as surgery.

[0150] [Correction pursuant to Rule 91 22.01.2026]

[0151] [Correction pursuant to Rule 91 22.01.2026] Meanwhile, another embodiment of the loupe unit of FIG. 4 can be detachably mounted on the main body arm (120) of the medical lighting device (10) described above to provide a magnified image to the user, thereby allowing work and surgery to be performed more easily and precisely.

[0152] [Correction pursuant to Rule 91 22.01.2026] Specifically, the loupe unit of this embodiment may include a magnifying glass, a loupe frame, a link arm, and a mounting part.

[0153] [Correction pursuant to Rule 26 22.01.2026] Since the configuration of the magnifying glass, loupe frame, and link arm in the loupe unit of this embodiment is applicable in the same way as the loupe unit (140) of the previously described embodiment, a detailed description thereof will be omitted for convenience.

[0154] [Correction pursuant to Rule 91 22.01.2026] In other words, since the mounting part of the loupe unit of this embodiment is different from the loupe unit (140) described above, only the mounting part will be described.

[0155] [Correction pursuant to Rule 91 22.01.2026] In detail, in this embodiment, a plurality of locking protrusions of the mounting portion are detachably coupled to a plurality of locking holes (123a) of the main body arm (120), and the locking protrusion located at the upper part of the front (face exposed in the Y-axis direction) when the end of the mounting portion moves vertically downward (Z-axis direction) may be formed longer than the locking protrusion located at the lower part.

[0156] [Correction pursuant to Rule 91 22.01.2026] Accordingly, the mounting part of the present embodiment has a structure in which a plurality of locking protrusions protrude forward (Y-axis direction) when vertically downward (Z-axis direction) from the link arm, and can be detachably mounted to a plurality of locking holes (123a) of the main body arm (120).

[0157] [Correction pursuant to Rule 91 22.01.2026] Therefore, even if the loupe unit of this embodiment has a link arm and a mounting part of the same length, the loupe frame can be positioned further away from the locking hole (123a) of the main body arm (120), so the user can use the magnifying glass at a more diverse position and adjust a more diverse viewing angle.

[0158] [Correction pursuant to Rule 91 22.01.2026] Of course, the mounting part of the loupe unit of this embodiment may also be mounted to the main body arm (120) in various ways, such as a detachable method using magnetic force or a screw fastening method, in addition to a detachable method using a plurality of locking protrusions.

[0159] As such, the present invention has been described with reference to an embodiment illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and variations of the embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims.
