Description

{LED Lighting Device for Medical Treatment}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical LED lighting device, and more particularly, to a medical LED lighting device capable of illuminating the inside of a human body for inspection, surgery and the like.

A separate lighting system would be used to observe the patient's sick or surgical site. For example, external light is reflected or directly accessed by a pen-type (or stick-type) lighting device to observe the mouth or nose (nasal cavity). However, since the length of such a pen-type lighting apparatus is fixed, there is a problem that it is impossible to illuminate deep inside if necessary.

In addition, in the case of surgery, the endoscope and the illumination were used separately from the external illumination in order to illuminate the deep area. However, even when only illumination is required, a conventional endoscope having a camera and various surgical apparatuses is used, so that there is a problem that a wound area becomes large.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is a primary object of the present invention to provide a medical LED lighting device capable of arbitrarily adjusting the length along its length direction.

It is a second object of the present invention to provide a medical LED lighting device capable of illuminating by minimally invasive or non-invasive approach to an area requiring illumination during surgery.

According to an aspect of the present invention, there is provided a power supply unit including: a power supply unit having a switch;

An LED light source 114 that emits light by receiving power from the power source unit 120;

A cylindrical body 110 for receiving the LED light source 114 therein;

A stretchable portion 140 provided at one end of the body portion 110 and expandable in an axial direction; And

And a scattering part 150 provided at an end of the stretchable and contractible part 140,

There is provided a medical LED illumination device characterized in that light of the LED light source (114) is irradiated around the scattering part (150).

It is also possible to further include an optical fiber 116, one end of which is connected to the LED light source 114 and the other end lies along the axial direction of the body part 110.

In addition, it is preferable to further include a support rib 118 protruding from the inner wall of the body 110 to support the optical fiber 116.

An object of the present invention is, as another embodiment, an LED light source unit 250;

A first optical fiber 240 once connected to the LED light source 250;

A second optical fiber 210;

A connection part 230 connecting or disconnecting the other end of the first optical fiber 240 and one end of the second optical fiber 210; And

And a scattering unit 220 provided at the other end of the second optical fiber 210. The medical LED lighting apparatus according to the present invention can be used for a medical LED lighting apparatus.

An object of the present invention is, as another embodiment, an LED light source unit 250;

A first optical fiber 240 once connected to the LED light source 250;

A second optical fiber 210;

A connection part 230 connecting or disconnecting the other end of the first optical fiber 240 and one end of the second optical fiber 210;

A scattering portion 220 provided at the other end of the second optical fiber 210;

And a bronchoscope 300 through which the first optical fiber 240 or the second optical fiber 210 can flow,

Characterized in that the second optical fiber (210) approaches the illumination region (420) through the bronchoscope (300) and the bronchoscope (300) can be removed through the disconnected connection (230) As shown in FIG.

An object of the present invention is, as another embodiment, an LED light source unit 250;

A second optical fiber 210;

A connection part 230 connecting or disconnecting one end of the LED light source part 250 and the second optical fiber 210;

A scattering portion 220 provided at the other end of the second optical fiber 210;

And a bronchoscope 300 through which the second optical fiber 210 can flow,

Characterized in that the second optical fiber (210) approaches the illumination region (420) through the bronchoscope (300) and the bronchoscope (300) can be removed through the disconnected connection (230) As shown in FIG.

The length of the second optical fiber 210 is preferably at least twice the length of the bronchoscope 300.

It is most preferable that the bronchoscope 300 further has a branch portion 310 and the second optical fiber 210 can flow through the branch portion 310.

The catheter may further include a catheter 350 into which at least one of the first optical fiber 240 and the second optical fiber 210 is inserted.

According to an embodiment of the present invention, in the case of a stick-type lighting apparatus, the length can be arbitrarily adjusted along the length direction, so that it is convenient to positively cope with various situations.

In addition, in the case of a bronchodilator, there is an advantage that an optical fiber can be easily injected using a bronchoscope. In addition, since the bronchoscope 300 is removed and illuminated with only a thin optical fiber (or a catheter), there is an advantage that it is easy to perform a test or operation.

In addition, since the scattering portion uniformly illuminates the periphery of the illumination region, it is possible to minimize the difference in contrast or shadowiness.

The power supply unit 120 is a primary or secondary battery 125 for supplying power to the LED light source 114. Although not shown, the power source unit 120 can be opened and closed by screwing the body unit 110, and the battery 125 can be replaced when the power source unit 120 is opened.

The body 110 has a hollow shape similar to a pen and may be made of metal or plastic material and houses a PCB 112, an LED light source 114, an optical fiber 116, and a supporting rib 118 .

The PCB 112 includes a connection terminal for connecting the battery 125 and the switch 130, a LED light source 114, and a control circuit (not shown) for the LED light source 114.

The LED light source 114 is a representative example of a white LED, but not limited thereto, LEDs of RGB or a laser light source are also possible.

One end of the optical fiber 116 is connected to the LED light source 114 and is installed along the central axis of the body 110 in a straight line. The optical fiber 116 extends approximately by the length of the body 110 and the other end is positioned to face the scattering unit 150.

The supporting ribs 118 protrude from the inner wall of the body 110 and fix the optical fiber 116 to prevent the optical fiber 116 from moving. The supporting ribs 118 may be arranged in an appropriate number (3 to 5) according to the length of the body 110.

The stretchable and contractible portion 140 is coupled to one end of the body portion 110 and is similar to a general antenna structure capable of extending and contracting in the longitudinal direction. That is, as shown in FIGS. 1 to 3, the stretchable and contractible portion 140 is constituted by four stages and constitutes first, second, third and fourth stretchable portions 140a, 140b, 140c and 140d. At the end of the fourth stretchable and contractible portion 140d, a scattering portion 150 is provided. The inner surfaces of the body 110 and the first, second, third and fourth stretchable and contractible portions 140a, 140b, 140c and 140d are preferably mirror-finished to increase the reflectance of light.

The scattering part 150 is a member for suppressing the straightness of the light transmitted through the stretchable and contractible part 140, The scattering portion 150 may be made of glass or plastic material having a large surface roughness or a conventional optical component.

Configuration of the second embodiment

FIG. 4 is a structural view of a bronchoscope illuminator 200 according to a second embodiment of the present invention, and FIG. 5 is a structural diagram of a state in which the bronchoscope 300 flows to the first optical fiber 240 side in FIG. 4 and 5, the bronchoscope illumination device 200 mainly comprises a bronchoscope 300 and an optical fiber and a light source unit 250.

The bronchoscope 300 may be a conventional bronchoscope. The branched portion 310 is a structure protruding to one side of the bronchoscope 300 so that the optical fiber can flow into the branch portion 310. The injection tube 320 is a thin flexible tube that can be inserted into the bronchial tree 400.

One end of the first optical fiber 240 is connected to the light source unit 250 and the other end is connected to the connection unit 230. The first optical fiber 240 may be inserted into the catheter 350.

One end of the second optical fiber 210 is connected to the connection part 230 and the scattering part 220 is formed at the other end. The length of the second optical fiber 210 is preferably at least two times longer than the total length of the bronchoscope 300 and the injection tube 320. This is because the second optical fiber 210 is located in the bronchus 400 So as to remove the bronchoscope 300. The second optical fiber 210 may be inserted into the catheter 350.

The scattering unit 220 is a member for suppressing the directivity of the light transmitted through the second optical fiber 210 and uniformly dispersing the light. The scattering portion 220 may be made of glass or a plastic material having a large surface roughness or a conventional optical component.

The connection part 230 is a connector for optically connecting the first and second optical fibers 240 and 210. Such a connection portion 230 is a structure (for example, a screw connection or a quick snap connection or the like) capable of connecting or disconnecting the optical fiber to or from the connection portion 230 according to need during surgery or inspection. In particular, the connection portion 230 may be configured to be inserted into the catheter, and the smaller the maximum outer diameter, the better.

The light source unit 250 is a component for emitting predetermined light. The light source unit 250 includes a light bulb, a fluorescent lamp, a halogen lamp, a white LED light source, and a laser light source. The light source unit 250 includes a control circuit, a switch, and a power source. The configuration of the light source unit 250 is a typical configuration and is obvious to those skilled in the art, so a detailed description of the configuration will be omitted.

Configuration of Third Embodiment

FIG. 8 is a structural view of a bronchoscope illuminating apparatus according to a third embodiment of the present invention, and FIG. 9 is a sectional view of A-A shown in FIG. Since the rough configuration of the third embodiment is the same as or similar to that of the second embodiment of FIGS. 4 and 5, the description of the redundant configuration will be omitted. 8 and 9, in the third embodiment, the first optical fiber 240 is omitted, and the connection unit 230 and the light source unit 250 are directly connected to each other. Accordingly, to remove the bronchoscope 300, the second optical fiber 210 and the connection unit 230 are disconnected.

In addition, the second optical fiber 210 is provided inside the catheter 350. The catheter 350 is shown in FIGS. 8 and 9, but may be applied to the embodiments shown in FIGS.

The operation of the first embodiment

Hereinafter, a first embodiment of the present invention will be described with reference to the accompanying drawings. 3, when the switch 130 is pressed with a finger (not shown), the power of the battery 125 is applied to the LED light source 114 through the PCB 112 to emit light. The emitted light is transmitted to the stretchable and contractible portion 140 through the optical fiber 116 without a large loss of light.

A part of the light irradiated from the end of the optical fiber 116 goes straight and the rest is reflected by the inner surfaces of the first, second, third and fourth stretchable portions 140a, 140b, 140c and 140d to reach the scattering portion 150 do. The scattering unit 150 spreads the emitted light relatively evenly around it.

Therefore, a medical person (e.g., a doctor or a nurse) can easily extend the stretchable portion 140 by hand and then easily reach the region of interest. Further, since the light is uniformly reflected by the scattering unit 150, the contrast of light and dark is small and the identification is easy without a wrong plate.

Operation of the second embodiment

Hereinafter, a second embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 6 is an explanatory view of a state in which the second embodiment shown in FIGS. 4 and 5 is installed in the bronchial tree 400, and FIG. 7 is an explanatory diagram of a state in which the bronchoscope 300 is removed in the state shown in FIG.

First, referring to Fig. 6, the bronchoscope 300 is inserted into the bronchus 400 of the patient. At this time, the injection tube 320 of the bronchoscope 300 is inserted so as to approach the illumination area 420. The illumination area 420 is an area requiring surgery or inspection, and observes or operates the lungs from the outside (for example, outside of the lung) in a state in which the light is irradiated through the bronchus 400.

Then, the second optical fiber 210 is inserted through the branch portion 310. At this time, the second optical fiber 210 is inserted considering the length of the injection tube 320 already known. Alternatively, the bronchoscope 300 may be inserted with the second optical fiber 210 injected into the bronchoscope 300.

Next, as shown in FIG. 7, the second optical fiber 210 and the connection unit 230 are disconnected (see arrows in FIG. 7). Then, the bronchoscope 300 is slowly pulled out from the bronchus 400 in a state in which the second optical fiber 210 is held so as not to come out (refer to arrows in Fig. 7). For this, the second optical fiber 210 is preferably at least twice as long as the combined length of the bronchoscope 300 and the injection tube 320 (since the second optical fiber must be held until the injection tube is completely exhausted).

Then, the first optical fiber 210 and the connection unit 230 are connected again, and the LED light source unit 250 is operated. The second optical fiber 210 can approach and illuminate the light up to the vicinity of the illumination area 420 by the series of operations. The optical fiber 210 can not be easily accessed only by the optical fiber without the bronchoscope 300 and the operation and inspection can be difficult in the state where the bronchoscope 300 is inserted. Has a great advantage over the prior art.

Although the present invention has been described in connection with the preferred embodiments set forth above, it will be readily appreciated by those skilled in the art that various other modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that all modifications are within the scope of the appended claims.
