Description

Shadowless surgical light with air injection function

[0001] The present invention relates to a surgical light without a shadow, and more particularly, to a surgical light without a shadow, which is equipped with an air injection function to enable a patient to have a good view of the affected area when performing surgery in an operating room and to prevent smoke generated during surgery from stagnating.

[0002] In general, a shadowless light refers to a lighting device designed to allow for a clear view of the affected area during surgery in hospitals, etc. It is designed to project light from all directions so that no shadows are created in the area where the surgery is being performed, and is positioned above the operating table.

[0003] These lights should be positioned directly above the operating table to avoid casting shadows, allowing for the best view of the affected area.

[0004] However, since the overhead light is usually manufactured in a circular shape, it acts like an umbrella in itself, preventing air coming down from the ceiling of the operating room or various harmful gases such as smoke generated during surgery from rising upwards, thereby hindering the flow of air and causing harmful gases to stagnate under the overhead light.

[0005] This poses a serious health risk to the surgical staff, as they could inhale harmful gases. This is particularly true when heat is used to cauterize skin tissue, such as with electrocautery, to remove polyps or tumors. This process generates significant amounts of smoke. If this smoke remains trapped under a strobe light, it can lead to significant inhalation, potentially leading to serious health problems.

[0006] The present invention has been devised to solve the problems of the above-mentioned prior art, and the purpose of the present invention is to provide a surgical light equipped with an air injection function that prevents smoke generated during surgery from stagnating under the surgical light, thereby preventing medical staff performing surgery under the surgical light from inhaling smoke, and at the same time, ensuring smooth airflow throughout the surgical field.

[0007] In order to solve the above-described problem, the present invention provides a surgical light equipped with an air injection function, comprising: a blower unit; a multi-joint support having a plurality of arms rotatably connected to each other and installed on the ceiling; an air injection frame having an open space formed in the center and rotatably and tiltably installed on the multi-joint support, which receives and injects air generated from the blower unit; and a plurality of LEDs installed on the lower surface of the air injection frame.

[0008] Here, the blower unit is composed of a housing; a blower motor installed inside the housing; a blower fan installed on the blower motor and rotating to generate wind; and a blower pipe connecting the housing and the air injection frame to provide wind generated by the blower fan to the air injection frame.

[0009] And, the air injection frame is composed of a lower surface on which the LED is installed; an outer surface extending upward from the outer edge of the lower surface and then being bent downward in a rounded manner toward the open space and connected to the blower pipe; and an inner surface extending upward from the inner edge of the lower surface and having an end portion overlapped with an end portion of the outer surface at a certain distance to form an air discharge path.

[0010] Meanwhile, a handle extending toward the center of the open space is installed in the air injection frame, and an insertion tube having a spiral formed on the outer surface of the handle and a plurality of vertical cutting lines formed at regular intervals is installed on the upper surface of the handle, and a ball that rotates in all directions within the insertion tube is provided on the arm of the multi-joint support, and a nut that is spirally connected to the insertion tube so that the inner surface of the insertion tube presses the outer surface of the ball is installed on the outer surface of the insertion tube.

[0011] In addition, a fine dust measurement sensor is installed on the bottom of the handle, and when the fine dust exceeds a certain amount, the control unit operates the blower unit.

[0012] Additionally, the ball is formed so that its diameter is larger than the diameter of the inlet of the insertion tube.

[0013] The surgical light equipped with an air injection function of the present invention configured as described above has an open space formed in the center of the air injection frame, so that harmful gases generated during surgery do not stagnate under the surgical light but rise upward through the open space, thereby preventing medical staff from inhaling harmful gases.

[0014] Additionally, there is an advantage in that the air inside the operating room and the harmful gases generated during surgery are not stagnant and flow smoothly due to the wind sprayed from the air spray frame.

[0015] In addition, there is an advantage in that the insertion tube can be freely tilted at a desired angle around the ball, and the tilting angle can be firmly maintained by tightening the nut on the outer surface of the insertion tube.

[0016] Additionally, the fine dust measurement sensor measures the amount of fine dust and automatically operates the blower unit when the amount exceeds a certain level, which has the advantage of automatically circulating the air within the operating room.

[0021] Hereinafter, an embodiment of a surgical light equipped with an air injection function according to the present invention will be described in detail with reference to the attached drawings.

[0022] FIGS. 1 to 3 are drawings showing a shadowless surgical light equipped with an air injection function according to the present invention, FIG. 4 is a drawing showing an air injection frame of the shadowless surgical light equipped with an air injection function shown in FIGS. 1 to 3 tilting, and FIG. 5 is a drawing showing air flow in the shadowless surgical light equipped with an air injection function shown in FIGS. 1 to 3.

[0023] And, Fig. 6 is a drawing showing another embodiment of a shadowless surgery lamp equipped with a prediction injection function according to the present invention.

[0024] The surgical light equipped with an air injection function according to the present invention comprises a blower unit (10), a multi-joint support (20) installed on the ceiling or wall of an operating room, an air injection frame (30) that receives air from the blower unit (10) and injects it, and a plurality of LEDs (40) installed on the lower surface of the air injection frame (30).

[0025] The above blower unit (10) is a device that generates wind and may be installed on the ceiling or inside the ceiling of the operating room, on the wall of the operating room, or on one side of the air injection frame (30). However, considering the weight of the surgical instrument and the environment inside the operating room, it may be preferable to install it on the inside of the ceiling of the operating room to minimize external exposure.

[0026] This blower unit (10) is composed of a housing (11), a blower motor (12) installed inside the housing (11), a blower fan (13) installed in the blower motor (12), and a blower pipe (14) connecting the housing (11) and an air injection frame (30).

[0027] The above housing (11) has an empty space formed inside to accommodate a blower motor (12) and a blower fan (13). A number of air holes (not shown) are formed in the housing (11), so that when the blower fan (13) rotates, external air is drawn into the housing (11) through the air holes.

[0028] The above blower motor (12) is electrically connected to the control unit (50) and is automatically operated or stopped by the control unit (50).

[0029] The above blower fan (13) rotates when the blower motor (12) operates to generate wind.

[0030] The above blower pipe (14) is in the form of a hose that can be freely bent or folded, and one end is connected to the housing (11) and the other end is connected to the air injection frame (30) to provide the wind generated by the rotation of the blower fan (13) to the air injection frame (30).

[0031] The above multi-joint support (20) is connected to a plurality of arms (21) so as to be rotatable, thereby allowing the position of the air injection frame (30) to be adjusted.

[0032] The above air injection frame (30) is manufactured in a ring shape, has an open space (30a) formed in the center, and is installed at the bottom of the multi-joint support (20) so as to be able to rotate and tilt.

[0033] This air injection frame (30) is composed of a lower surface (31), an outer surface (32) integrally formed on the outer edge of the lower surface (31), and an inner surface integrally formed on the inner edge of the lower surface (31).

[0034] The above-mentioned area (31) is formed in a circular shape with a certain width as a part where the LED (40) is installed, and is located above the operating table in the operating room.

[0035] The above outer surface (32) extends upward from the outer edge of the lower surface (31) and is then rounded downward toward the open space (30a). This outer surface is connected to the air blower pipe (14).

[0036] The inner side (33) extends upward from the inner edge of the lower surface (31) and overlaps the end portion of the outer side (32) with a certain distance between them. Accordingly, an air discharge path (34) is formed between the end portion of the outer side (32) and the end portion of the inner side (33).

[0037] The above air discharge path (34) is formed in a circular shape along the distance between the end of the outer surface and the end of the inner surface (33) and serves as a passage for discharging the wind that has flowed into the air injection frame (30). When the wind is discharged from the air discharge hole (34), the surrounding pressure decreases and the surrounding air flows toward the open space (30a), thereby promoting the flow of air.

[0038] Meanwhile, the air injection frame (30) is installed on the multi-joint support (20) in a rotatable and tiltable manner, and its structure is described in detail as follows.

[0039] A handle (35) extending toward the center of the open space (30a) is installed at the end of the outer surface (32) or the end of the inner surface (33) of the air injection frame (30). An insertion tube (36) is installed on the upper surface of this handle (35).

[0040] The above handle (35) is configured in the shape of a bar and is used to adjust the angle of the air injection frame (30), and a number of LEDs (40) are installed on the bottom surface.

[0041] The above insertion tube (36) has a spiral formed on the outer surface, and a number of vertical cutting lines (36a) are formed at regular intervals.

[0042] Since the above-mentioned incision line (36a) is formed by starting from the top of the insertion tube (36) with a constant width and extending in a straight line toward the downward direction, the insertion tube (36) takes the form of a plurality of pieces having a spiral formed on the outer surface connected to each other at the bottom.

[0043] In addition, a ball (37) is provided on the arm (21) of the multi-joint support (20), and a nut (38) is spirally connected to the outer surface of the insertion tube (36).

[0044] The above ball (37) is provided on the lowest arm among the multiple arms (21) constituting the multi-joint support (20), and is inserted into the insertion tube (36) through the open upper surface of the insertion tube (36) and rotates in all directions within the insertion tube (36). The diameter of this ball (37) is formed to be larger than the diameter of the upper surface entrance of the insertion tube (36).

[0045] As described above, the insertion tube (36) is formed by connecting multiple pieces at the bottom, and the diameter of the ball (37) is larger than the diameter of the entrance of the insertion tube (36). Therefore, when the ball (37) is inserted into the insertion tube (36), the multiple pieces forming the insertion tube (36) slightly open outward from the bottom and then close inward.

[0046] The inner surface of the above nut (38) is spirally connected to the outer surface of the insertion tube (36), so that the inner surface of the insertion tube (36) strongly presses the outer surface of the ball (37), thereby preventing the rotating or tilted air injection frame (30) from moving.

[0047] That is, after rotating / tilting the air injection frame (30) to the required angle during surgery, the insertion tube (36) is strongly pressed with the nut (38) to prevent the air injection frame (30) from moving in the ball (37).

[0048] In addition, as described above, the blower pipe (14) is directly connected to the air injection frame (30), but as shown in FIG. 6, by connecting the blower pipe (14) to the inside of the arm (21) having an air path formed therein and simultaneously forming an air path communicating with the air injection frame (30) inside the ball (37) and the handle (35), it is also possible to supply the air created by the blower unit (10) to the inside of the air injection frame (30) through the internal paths of the arm (21), the ball (37), and the handle (35).

[0049] Meanwhile, a fine dust measurement sensor (35a) electrically connected to a control unit (50) is installed on the bottom of the handle (35). Accordingly, when the fine dust measurement sensor (35a) detects that the amount of fine dust exceeds a certain amount while measuring the amount, it transmits this signal to the control unit (50), and the control unit (50) that transmitted the signal operates the blower unit (10). When the blower unit (10) operates through this process, wind is sprayed from the air injection frame (30) to circulate stagnant air.

[0050] In addition, if the blower fan (13) rotates in the forward direction when blowing wind from the air injection frame (30), the blower motor (12) can be operated in the reverse direction to cause the blower fan (13) to rotate in the reverse direction, thereby sucking air containing harmful gases inside the operating room into the housing (11) through the air discharge path (34) and the blower pipe (14). The air sucked in this way can also be discharged outside the operating room through a separate pipe connected to the housing (11).

[0051] The above LED (40) is used to illuminate a patient lying on an operating table so that the affected area can be seen clearly, and a plurality of LEDs are installed on the lower surface of the air injection frame (30) and the bottom surface of the LED (40).
