Description

Operating lights with dual reflector

The present invention relates to an operation table or a surgery lamp used in a treatment table, and more particularly, to an operation lamp equipped with a double reflector that makes it easy to adjust the irradiation angle while preventing the light emitted from the light source from being directly irradiated to the surgical site. will be.

Conventional lighting used to brighten the affected area of a patient on an operating table or a treatment table is a halogen-free lamp. While the halogen-free lamp concentrates a light source on the corresponding area to prevent shadows from being generated, when used for a long time, the area to be treated becomes dry due to heat and causes sweating, causing discomfort from sweat.

In addition, due to the short lifespan, the amount of light decreases rapidly over time, requiring frequent replacement, and since mercury gas is used inside, there is a problem that environmental pollution occurs during disposal.

In order to improve the problem of such a halogen light-emitting light, in recent years, an LED light-emitting diode (LED) is in the spotlight.

LEDs are semi-permanently longer in life than halogens and have excellent energy efficiency due to low power consumption, which can reduce electricity bills. In addition, LEDs can be said to be more eco-friendly than halogen because no harmful substances such as filaments or mercury are used.

However, since LEDs form a higher price than halogen, there is a problem that the manufacturing cost increases relatively when LEDs are used a lot.

In addition, when electric energy is applied to the LED, the outermost electrons of the semiconductor are excited, and they are located at a high energy level and then return to their orbit to generate their own light and heat.

At this time, only about 15% of the total energy of the LED is converted into light and the rest is released as heat, so the heat dissipation problem must be solved in order to be used as a shampoo lamp used in an operating table or a treatment table.

In addition, it is necessary to solve the problem of increasing the temperature of the surgical site by the heat energy emitted with the light by directly irradiating the light irradiated from the LED to the surgical site.

In the domestic registration patent No. 10-1300732 shown in FIG. 1 "hospital medical treatment lighting device that can also serve as a no-young lamp", the lighting lamp body 20, the movable lighting lamp body 30, the slide bar 40, and the cross-shaped support 50 ) Is proposed.

However, in the above invention, the LED light is directly irradiated to the surgical site, and there is a risk of exposure to bacterial infection by increasing the temperature of the surgical site by the light irradiation heat.

In addition, in order to prevent the occurrence of shadows, it has a complicated structure in which the movable lighting body 30 must be pulled out and used, and there is a problem in that the body must be held and operated by hand during the operation in order to pull out and insert the movable lighting body 30 .

In addition, metal beads or plastic beads are used as a locking means used to fix the slide bar 40. When the locking means is worn, there is a risk that foreign substances and the like fall to the surgical site, making it difficult to secure a sterile state.

Domestic Registration Patent No. 10-1180132'medical lighting device' shown in FIG. 2 is to avoid direct irradiation of LED light, and a light source module 110 constituting the hat part 120 in which a plurality of light emitting diodes 125 are installed And an elliptical hemispherical reflector 130 formed to reflect light emitted from the light emitting diode 125 in the extending direction of the light source module 110.

In the present invention, in order to prevent a plurality of light emitting diodes 125 from being directly irradiated to the surgical site, the hat part 120 is disposed at the bottom to irradiate light to the reflector 130 located at the top.

That is, the light reflected by the reflector 130 is configured to illuminate the surgical site, so that the irradiation heat of light is reduced.

However, since the hatch part 120 in which a plurality of light emitting diodes 125 as light sources are installed is disposed below and irradiates light to the top, heat radiated to the rear of the hatch part 120 is difficult to heat radiation. There is a problem that raises.

In order to solve the above problems, the present invention is to provide a surgical lamp equipped with a double reflector that can increase light efficiency by reflecting LED light so that the outgoing light is not directly irradiated to the surgical site.

As shown in Figures 3 and 4, the present invention is a surgical lamp equipped with a double reflector housing (1) covering the upper portion of the surgical lamp; A transmission panel 2 coupled to the lower portion of the housing 1; A light source unit 3 coupled to the central lower surface of the housing 1 to emit light; A handle part 4 which is rotatably coupled through the center of the transmission panel 2; A first reflector (5) for reflecting the light emitted from the light source (3) to be obliquely upward, and is screwed to the upper end of the handle (4) to move up and down according to the rotation of the handle (4); And a second reflector 6 provided on a lower surface of the housing 1 to re-reflect light reflected from the first reflector 5 downward. It characterized in that it consists of.

An object of the present invention is to provide a surgical lamp equipped with a double reflector in which light emitted from a light source is not directly irradiated to a surgical site and at the same time, an irradiation angle can be easily adjusted.

The housing 1 is configured to cover the upper part of the surgery lamp.

In the housing 1, an arm 8 for fixing a surgical lamp to a structure such as a ceiling is coupled to one side, and a light source 3 and a second reflector 6 to be described later are coupled to a lower inner circumferential surface.

A controller 9 capable of adjusting an operation such as surgery may be coupled to the arm 8.

The transmission panel 2 is coupled to the lower portion of the housing 1.

The transmission panel 2 may be coupled to close the lower portion of the housing 1.

Accordingly, a certain space is formed between the housing 1 and the transmission panel 2, and the light source 3, the first reflector 5, and the second reflector 6 are located in the space.

A handle part 4, which will be described later, is provided through the center of the transmission panel 2.

The transmission panel 2 may be made of glass or plastic made of a transparent material so that the light source is irradiated to the surgical site.

The transmission panel 2 may attach a film for preventing diffuse reflection in order to prevent diffuse reflection of transmitted light.

The light source unit 3 is coupled to the lower surface of the center of the housing 1 to emit light.

The light source unit 3 may include an LED module 31, a lens 32 for diffusing the LED light source, and a heat dissipation block 33 for discharging heat generated from the LED module 31 to the upper portion of the housing 1.

The lens 32 and the heat dissipation block 33 may be positioned below and above the LED module 31, respectively.

The heat dissipation block 33 effectively radiates heat generated from the LED module 31 upward.

Therefore, the temperature of the central portion of the housing 1 can be maintained at an appropriate level.

The handle part 4 penetrates through the center of the transmission panel 2 and is rotatably coupled.

The handle part 4 is rotatably coupled to the transmission panel 2.

The handle part 4 has an upper portion protruding from the upper portion of the transmission panel 2 and a lower portion protruding from the lower portion of the transmission panel 2.

Accordingly, the operator can easily adjust the angle of surgery, etc. by holding the handle part 4 protruding downward.

The first reflector 5 reflects the light emitted from the light source unit 3 to be inclined upward.

The first reflector 5 primarily reflects the light emitted from the light source unit 3 in an upward and outward direction.

To this end, the first reflector 5 may be formed in an eight-shaped shape inclined downward toward the outside in cross section.

The first reflector 5 is screwed to the upper end of the handle part 4 and moves up and down according to the rotation of the handle part 4. Accordingly, since the reflection angle of light emitted from the light source unit 3 can be adjusted only by rotating the handle unit 4, the irradiation range and angle of the light irradiated to the surgical site can be finally adjusted.

The first reflector 5 may have a reflective surface such as a reflector formed on an upper surface.

The second reflector 6 is provided on the lower surface of the housing 1 to re-reflect the light reflected from the first reflector 5 downward.

The second reflector 6 may be formed in an elliptical hemispherical shape with an open lower surface as a whole, so that the light source distribution on the irradiated surface may be uniform.

The second reflector 6 may have a reflective surface such as a reflector formed on an inner surface thereof.

By the reflective surface, the LED light source can be narrowly condensed to a constant focus, thereby increasing the degree of concentration of the surgeon's surgery.

Among the light sources projected onto the second reflector 6, infrared rays are emitted to the upper surface of the second reflector 6 and only visible light is selectively reflected. Therefore, it is possible to suppress an increase in the temperature of the surgical site due to infrared rays.

In addition, the emission light emitted from the light source unit 3 is first irradiated to the first reflector 5 and secondly irradiated to the second reflector 6 and then to the surgical site. Accordingly, the heat of the LED light source may drop rapidly while passing through the first and second reflectors 5 and 6.

The second reflector 6 may be spaced apart from the housing 1 by a predetermined distance.

The lower portion of the first reflector 5 has a screw coupling hole 511 formed in the center and a nut portion 51 with limited rotation is provided, and a screw head having a screw thread formed on the outer circumferential surface above the handle portion 4 ( 41) is provided so that the screw head 41 may be configured to be screwed into the screw coupling hole 511 of the nut part 51.

The nut part 51 can only move up and down in a state where rotation is limited.

Therefore, when the handle part 4 is rotated, the screw head 41 rotates, and the nut part 51 coupled thereto does not rotate, but rises or falls.

A lower plate 52 supporting the first reflector 5 may be coupled to a lower portion of the first reflector 5. In addition, the nut portion 51 may be coupled to be positioned under the lower plate 52.

5 is an exploded perspective view showing a coupling relationship between a nut portion and a support, and FIG. 6 is a cross-sectional view showing an operation relationship of the first reflector.

A support 7 is provided between the transmission panel 2 and the first reflector 5.

The support 7 may be stably supported under the housing 1 by a plurality of support bars 71.

When the handle part 4 rotates, when the nut part 51 is rotated together with the handle part 4, the vertical movement of the first reflector 5, that is, the vertical movement of the first reflector 5, is difficult to proceed. .

Therefore, in order to prevent the nut part 51 from spinning, one or more guide holes 512 are formed through the nut part 51 and the guide shaft 72 is inserted into the guide hole 512, thereby The part 51 may be configured to be movable only in a vertical direction.

At this time, the guide shaft 72 is coupled to the support 7, and in order to prevent the entire support 7 from being idle, the support 7 is placed in the lower part of the housing 1 by the support bar 71. Fix it.

The support 7 may be provided with a support block 73 at an upper center thereof. In addition, the guide shaft 72 may be coupled to the upper portion of the support block 73.

A stop bracket 74 may be provided at an upper end of the guide shaft 72 to limit an upper movement distance of the nut part 51.

When the handle portion 4 is excessively rotated, there is a possibility that the nut portion 51 may be separated from the top of the screw head 41. Therefore, by protruding the stop bracket 74 on the upper end of the guide shaft 72, the nut portion 51 is caught on the lower end of the stop bracket 74 to prevent the screw head 41 from being separated from the top.

That is, as shown in (b) of FIG. 6, when the stop bracket 74 is coupled to the upper end of the guide shaft 72, when the nut part 51 reaches the upper position of the screw head 41, the nut The part 51 is caught on the lower end of the stopping bracket 74 and cannot be raised any more.

7 is a cross-sectional view showing a handle portion.

As shown in FIG. 7, the handle part 4 is detachable to the outside of the screw head 41, the handle body 42 coupled to the lower portion of the screw head 41, and the handle body 42 It can be configured with a disinfecting handle 43 that is covered in a way.

The handle part 4 may include a screw head 41, a handle body 42, and a disinfection handle 43.

The screw head 41 is screwed with the nut portion 51 of the first reflector 5.

As the screw head 41 is rotated by the rotation of the handle body 42, the first reflector 5 is raised or lowered.

At this time, since the handle part 4 may be contaminated before or during surgery, it is preferable to configure a sterilized disposable.

To this end, a disinfecting handle 43 that can be detached from the outside of the handle body 42 for elevating the first reflector 5 may be covered.

The disinfection handle 43 can be disposed of by separating it from the handle body 42 after one use.

At one side of the handle body 42, a pressing shaft 44 that is elastically supported in the handle body 42 is protruded, and the pressing shaft 44 is inserted into the disinfecting handle 43 to be caught. It can be configured so that the ball 431 is formed.

One end of the pressing shaft 44 is elastically supported inside the handle main body 42, and the other end thereof is directed to the outside of the disinfection handle 43 through a locking hole 431 formed on one side of the disinfection handle 43. Exposed.

The pressing shaft 44 is not separated from the handle body 42 by coupling a stopper ring 45 to one end.

The pressing shaft 44 is elastically supported by the handle body 42 by a spring 46 provided on an outer circumferential surface.

The disinfection handle 43 can easily be coupled to and disassembled with the handle body 42 by a pressing shaft 44 that is elastically supported in the handle body 42.

Accordingly, when the disinfecting handle 43 is coupled to the handle body 42, the pressing shaft 44 is caught in the locking hole 431 and the disinfecting handle 43 can be prevented from being removed from the handle main body 42. .

Conversely, in the case of removing the disinfecting handle 43 from the handle body 42, the disinfecting handle 43 is released after the pressing shaft 44 is released from the locking hole 431 by pressing the outer end of the pressing shaft 44. ) Can be removed.
