However, in an embodiment of the present invention, a light outlet 104 is formed at one side of the case 101 of the handpiece 100 to output light in the form of a line, and a line-shaped So that the light can be irradiated to the foreign skin 1 such as external skin or teeth through the light outlet 104.

In the handpiece 100 according to the present invention, the circular light output from the light generating unit 2 is received and converted into a light having a line shape (line-shaped light) Lt; / RTI >

That is, the handpiece 100 of the present invention includes a beam transformer that converts light output from the light generator 2 into light in a strip shape and outputs the light. In one embodiment, the optical transformer includes a handpiece (100).

1 and 2, the light in the form of a line outputted from the optical transformer mounted in the inside is outputted to the outside through the light outlet 104 of the handpiece 100, .

In the present invention, the light generating unit 2 may include a light emitting diode (LED) as a light source.

The light generating unit 2 and the handpiece 100 may be directly connected to each other so that the circular light output from the light generating unit 2 is directly input to the optical transformer. It is preferable that the light generating unit 2 and the handpiece 100 are connected to each other by the optical transmission unit 3.

In this case, the optical transmission unit 3 may be constructed using an optical fiber that transmits light, and an optical cable 3 using an optical fiber is connected between the light generation unit 2 and the handpiece 100, The circular light output from the light source 2 is transmitted to the optical transformer through the optical cable 3, and then converted into light of a line shape so as to be output.

The optical transformer 110a includes optical means 111, 112 and 113 arranged at the front and back positions on the optical path in the case 101 of the handpiece 100. Circular light introduced into the handpiece 100 passes through optical means And is configured to be converted into a light in a line shape while passing through the line.

In the preferred embodiment, the optical transformer 110a includes a first optical means 111 for primarily deforming the circular light introduced into the handpiece 100 into a light in the form of a line, And a second optical means 112 arranged on the optical path of the first optical means for adjusting the lateral width and the length of the light by secondarily deforming the stripe-shaped light incident from the first optical means.

In addition, a third optical means 113 for transmitting the circular light introduced into the handpiece 100 to the first optical means 111 is disposed on the front side of the optical path of the first optical means 111 .

The first optical means 111 may be a lens (a so-called 'line lens') that can convert circular light into light in the form of a stripe, for example, a Powell lens or an array lens lens, and a cylindrical lens.

It is also applicable to a configuration using a known lens or optical element capable of converting circular light into linear light.

The third optical means 113 is an optical means for adjusting all the circular light to be incident on the rear first optical means 111 without a maximum light loss and is a circular light introduced into the handpiece 100 Or parallel light to be incident on the first optical means 111, and may include a PCX lens, a collimating lens, or a PCV lens.

In this manner, the circular light introduced into the handpiece 100 by the optical transformer 110a having the above-described configuration can be converted into the light in the form of a line and finally output through the light outlet 104. As described above, In the configuration of the optical transformer 110a, as shown in Fig. 3 (a), a top-hat mode beam profile in which the power in the longitudinal direction is uniform in the finally outputted line- (B), it is preferable that the power can be deformed so as to have the shape of a Gaussian mode in the width direction.

The handpiece of the present invention can be applied to a phototherapy medical instrument of various fields because an appropriate lens can be selected and used according to the wavelength of light output from the light generator.

3, the case 101 of the handpiece 100 includes a case body 102 having one side opened and an optical transformer 110a housed therein, And a cap 103 that is assembled with the cap 103.

The cap 103 is assembled on the side where light in a line form is output, and the cap 103 has a light outlet 104 for outputting light in a line form to the outside.

It is preferable that the cap 103 is screwed to the opening of the case body 102. The optical output of the optical transformer 110a housed in the case body 102 and the cap 103 So that the distance between the light outlets 104 formed in the light guide plate 104 can be adjusted.

That is, when the cap 103 is rotated, the cap is moved back and forth in the case body 102, and the optical output portion of the optical transformer 110a housed in the case body 102 And optical distance between the light outlets 104 of the cap can be made to be distant from or close to each other.

In this case, when the light in the form of a line in the optical transformer 110a is output in the form of diffused light extending in the longitudinal direction as shown in FIG. 3, the cap 103 is returned, ) Can be adjusted.

Since the cap and the light outlet cut off the light in the longitudinal direction end portion and only the light passing through the light outlet is irradiated to the ring portion, the length of the light irradiated to the ring portion is variously changed .

The thread 103a of the cap 103 and the thread 102a of the case body 102 are coupled to each other so that the cap can be moved in the opening of the case body, The distance between the light outlets 104 of the light guide plate 104 is adjusted.

In addition, the handpiece 100 of the present invention can be used for a plurality of replacements for different types of light therapy conditions in the dermatology, dentistry, otorhinolaryngology, etc., Caps 103-1 and 103-2.

FIG. 4 shows various examples of handpieces having different shapes of caps. As shown in FIG. 4, the cap 103, which outputs light in a strip form, or a portion (tip) And the length of the light can be varied due to the shape difference in the replaceable cap 103. [

Also, even if the replacement cap 103 has the same shape, the length of the light can be changed according to the size of the light outlet 104.

In the embodiment of the present invention described above, the width of the light irradiated to the lesion portion may vary depending on various conditions such as the configuration of the optical transformer, that is, the arrangement and specifications of the lens, and the width ) Can be made from several tens of micrometers to several millimeters.

It is possible to configure the width of the light irradiated through the optical transformer to be in the range of 10 mu m to 3 mm at the ring portion.

Accordingly, when the width of the light is greatly adjusted, it is possible to achieve the same effect as irradiating the ring portion with substantially planar light, and it becomes possible to irradiate the ring portion with a large area easily and conveniently at the time of use.

FIG. 6 illustrates the shape of light irradiated to the affected part through the optical transformer in the embodiment of the present invention. FIG. 6 (a) shows that light irradiation can be substantially performed on the affected part when the width of the light is increased.

Further, in the embodiment of the present invention described above, a plurality of optical transformers may be constituted. In this case, since it is possible to irradiate a plurality of stripe-shaped lights continuously in the width direction to the affected part, (Multiple lines of light are combined to form a surface investigation).

Therefore, as compared with the method of continuously scanning one line of light to the affected part, it is possible to simultaneously irradiate a plurality of lines of light to neighboring areas, .

In order to achieve this, several optical transformers having the same configuration are arranged side by side in the handpiece, and at the same time, an optical coupler, which divides the light output from the light generating unit into a plurality of lights and inputs them to the respective optical transformers, As shown in Fig.

In this case, the light transmitted from the light generating unit is divided into N lights by the 1: N optical coupler, and the divided light passes through each optical transformer (N pieces) So that light in the form of a plurality of strips can be irradiated to the affected part in the width direction.

FIG. 6 (b) shows the shape of the light irradiated to the affected part in the embodiment using a plurality of optical transformers, and shows a state in which a plurality of stripe-shaped lights are simultaneously irradiated to neighboring parts of the affected part.

(a portion where light is not irradiated is present between portions irradiated with circular light exists) as shown in Fig. 3 (c). In the case of (b) It can be seen that there is a clear advantage that the unexamined portion is minimized.

On the other hand, it is possible to use a slit member in which a line-shaped slit 111a is formed in the optical transformer 110a instead of the optical lens (line lens) described above as the first optical means 111, 5 is a view showing an example of a slit member usable as the first optical means 111. Fig.

As shown in the drawing, the slit member 111 has a structure in which a slit 111a is formed in the center so as to pass light in a stripe form. When such a slit member is used as a first optical means disposed on the optical path, Can be output as light in the form of a line by the slit 111a.

That is, the slit member 111 is provided to selectively pass a part of the circular light incident through the slit 111a, which blocks a part of the circular light and selectively transmits light only through the slit 111a And the circular light can be processed into a light in the form of a line by the slit member 111.

At this time, a PCX lens or a cylinder lens for collecting light can be arranged by the second optical means 112 disposed on the output side of the slit member 111, or a rod lens, a PCV lens, a collimating lens, The array can be arranged to collect light in a strip form passing through the slit 111a and to transmit a light image in a strip form.

On the other hand, the above-described embodiment is an embodiment using one optical lens as the first optical means in the optical transformer, wherein the optical lens of the first optical means can form circular light into a light in a line shape One line lens, that is, a well lens, an array lens, a cylinder lens, or the like can be used.

However, in a configuration in which a plurality of lenses arranged along the optical path are combined, that is, a structure capable of producing light in the form of a line using a plurality of lenses, this is also adopted as the first optical means of the optical transformer It is possible.

In this case, in the above description, a combination of the listed lenses may be adopted as an example that can be used as the second optical means, and optical means for arranging a plurality of lenses in front of and behind the optical path to produce light in a line shape do.

For example, at least one kind or at least two kinds of lenses selected from among a cylinder lens, a PCX lens, a rod lens, a PCV lens, a collimating lens, and a rod lens array are arranged before and after the optical path, Optical means can be constituted.

Such a combination of a plurality of lenses may also be included in the category of the first optical means because the circular light can be made into a light in a stripe form. Hereinafter, the optical means combining a plurality of lenses It will be referred to as a first optical means.

7 is a view showing an embodiment in which first optical means are applied to a plurality of lenses. In this case, the first optical means 111 of the optical transformer 110a is arranged by arranging two lenses 111b and 111c in the front- As shown in Fig.

8 shows an example of a configuration in which two PCX lenses 111b and 111c are combined by the first optical means 111. As shown in FIG. 8, lenses of the same kind are arranged in different directions (that is, Or it is possible to constitute a first optical means capable of arranging different types of lenses back and forth so as to form a light in a stripe form.

In FIG. 8, the two PCX lenses 111b and 111c constituting the first optical means 111 are shown to have the same size. However, the two lenses may be the same size or different size.

In this configuration, the second optical means 112 may have the same configuration as the second optical means of the embodiment of FIG. 3, and thus the first optical means 111 and the second optical means 112 in the embodiment of FIG. All can be made up of a cylinder lens, a PCX lens, a rod lens, a PCV lens, a collimating lens, and a rod lens array.

The lens of the second optical means 112 is disposed on the rear side of the optical path in the case 101 and the lenses 111b and 111c of the first optical means 111 are disposed on the front side of the second optical means.

At this time, when the positions of the lenses constituting the first optical means 111 and the second optical means 112 and the distance between the lenses are changed, the length of the light output from the handpiece may be different, The length of the light output from the handpiece can be adjusted according to the position of the output side lens, that is, the rear lens 111c on the optical path.

In addition, in both the embodiment of Fig. 3 and the embodiment of Fig. 7, only the lens located at the rear side (the output side of the handpiece) on the optical path, that is, the lens of the second optical means 112, Or the lens of the rear lens 111c and the lens of the second optical means 112 of the lenses of the first optical means 111 are fixed inside the cap 103 of the case 101 The length of the light output from the handpiece 100 can be adjusted by adjusting the front and rear positions of the cap 103 in the case body 102. In this case, And so on.

The present invention can be applied to a configuration in which a plurality of combined lenses can form a light in a line shape without necessarily using a single line lens in the means (first optical means) It is to be understood that the embodiment employing the configuration is also included in the scope of the present invention.

In addition, in the embodiments of Figs. 3 and 7, since the first optical means is capable of producing light in the form of a stripe, it is also possible to construct the optical transformer of the handpiece by deleting the second optical means.

Meanwhile, the hand piece according to the present invention may be a light source in which the optical transformer outputs a slightly curved, curved line-shaped light rather than a straight line by selecting a lens used in each optical means and various combinations thereof.

In other words, the handpiece according to another embodiment of the present invention includes an optical transformer that outputs a curved line-shaped light like a C-shape. The handpiece includes an optical transformer, such as a tooth (lateral side of a tooth) A curved form of light in the form of a line may be more suitable.

FIGS. 3 to 7 show linear shapes of the light output from the handpiece. FIG. 9 shows an embodiment in which light in the form of a C-shaped line is output instead of a straight line. In the case where an optical transformer And the third optical means 111, 112, and 113 constituting the optical transformer, the optical transformer outputs the light in the form of a curve in the shape of a curve, which is typified by the C-shape instead of the linear (straight-line) Respectively.

In FIG. 9, since various combinations of lenses and optical means are possible, optical means are all shown in the same shape. However, as each optical means, a selected one of the lenses of the optical means mentioned above may be used, The optical means 111 may be a slit member having slits formed therein.

However, when the slit member is used as the first optical means 111, the shape of the slit in the slit member should be a curved shape such as a C shape instead of a straight shape (linear shape) illustrated in FIG.

In the embodiment of FIG. 9, the C-shaped strip-shaped light passing through the first optical means 111 is output after being deformed by the second optical means 112, Or may be used to adjust the length of the light, or may be used to deform the light itself in the case where the transmitted light is C-shaped.

For example, when the size of the second optical means 112 is made smaller than a certain level in consideration of the size of light passing through the first optical means 111, the C-type light as shown in FIG. 9 (a) On the contrary, when the size of the second optical means is made larger than a certain level, the C-shaped light having the opposite shape as shown in (b) can be outputted.

As described above, the shape of the C-type light can be changed according to the size of the light passing through the first optical means and incident on the second optical means, the size of the second optical means, and the like. An appropriate size of the light and the second optical means incident on the second optical means in the optical means needs to be selected.

Next, FIG. 10 is a view showing another embodiment of the present invention, which shows a different embodiment of the construction of an optical transformer made up of optical means packaged in a case of a handpiece.

In the embodiment of FIG. 10, a slit member 121 for making the light finally output to the light output portion, which is the rearmost portion on the light path in the case (not shown) of the handpiece, .

Since the size and shape of the final output light are determined by the slit 121a, the size and shape of the slit 121a can be adjusted to a desired value, It is designed in consideration of the size and shape of the light to be irradiated to the site.

10 shows a perspective view of the slit member 121. Referring to FIG. 10, the shape of the C-shaped slit 121a formed in the slit member 121 can be seen. In the embodiment of FIG. 10, ) Is disposed on the most rear side in the handpiece case instead of the second optical means.

10, when the first optical means 111 for changing the size and shape of the circular light transmitted through the third optical means 113 is provided on the optical path, The slit member (3) is disposed on the rear side of the third optical means (113), and the light transmitted through the first optical means is formed into a curved shape, that is, a C- 121 are disposed.

The third optical means 113 for transmitting circular light introduced into the handpiece case may be a PCX lens, a collimating lens or a PCV lens as in the embodiment of FIGS. 3 to 9, Is the same as the third optical means of the embodiment described.

Further, the first optical means 111 may be the same as the configuration applied to the embodiment of FIG. 3 or 7, and the circular light transmitted through the third optical means 113 may be converted into linearly shaped light And transmits it to the slit member 121.

10 shows an embodiment in which a first optical means 111 in which a plurality of lenses 111b and 111c are combined is used as in the embodiment of Fig. 7, and a plurality of lenses 111b And 111c of the slit member 121, and the slit member 121 finally deforms the light into C-type light and outputs the light.

At this time, the linear light output from the first optical means 111 must be able to be deformed into C-type light by a method in which only a part thereof passes through the slit 121a of the slit member 121 and the rest is blocked , It must have a sufficient width so that it can be processed into C type light itself.

In the embodiment of Fig. 10, since the final C-type optical shape is formed by the slit member 121 on the most rear side in the light path, the third optical means 113 is provided between the third optical means 113 and the slit member 121, It is also possible to dispose a single cylinder lens, a PCX lens, a rod lens, a PCV lens, a collimating lens, or a rod lens array instead of the first optical means made up of a plurality of lenses or the first optical means shown in Fig. (Application of the lens used as the second optical means in the embodiment of Fig. 3).

It is needless to say that if it is desired to obtain linear light other than the C type light in the shape of the light finally output from the handpiece, A slit member having a straight slit as illustrated in Fig.

In the embodiment of FIG. 10, when the plurality of lenses 111b and 111c are used as the first optical means 111, the length of the 'C' shaped light can be adjusted when adjusting the distance between the front and rear lenses, It is possible to output the shape of the C-type light in the opposite direction according to the direction of the slit member 121 as shown in (a) and (b).

10 can be manufactured by freely changing the shape of the slit 121a formed in the slit member 121. Therefore, the embodiment of the present invention has an advantage that the shape of the finally output light can be variously changed to a shape more suitable for a treatment site .

Next, another embodiment in which the configuration of the optical transformer is changed will be described.

11 is a view illustrating a handpiece according to another embodiment of the present invention. In the illustrated embodiment, the handpiece 100 includes an optical transformer 110b that is exposed to the outside.

That is, the handpiece 100 includes the handpiece body 105 and the optical transformer 110b, which is formed by optically coupling the optical fiber 114 to the handpiece body 105 so as to extend outwardly from the handpiece body 105, .

The handpiece body 105 serves to output light from the light generating unit to the optical fiber 114 and to input the light to the optical fiber 114. The handpiece body 105 serves as a handle that the user can hold by hand, And the like.

The optical fiber 114 of the optical transformer 110b may be an optical fiber in which long-period gratings 115a are formed in a predetermined section.

The long period grating 115a is formed by arranging layers having different refractive indexes periodically in the longitudinal direction of the optical fiber 114 in a portion of the core 115 through which the light passes and is applied to a sensor system such as an optical communication system or a pressure sensor .

In the optical fiber 114, when the incident light meets the long period grating 115a, the optical fiber 114 couples with the cladding layer 116 surrounding the core 115 and goes out of the cladding layer.

Accordingly, when the jacket layer 117 surrounding the cladding layer 116 of the optical fiber 114 is peeled off, light is emitted outward by the length of the long period grating 115a, and light of a long form is emitted in the longitudinal direction of the optical fiber .

When one end of the optical fiber 114 having the long period grating 115a formed therein is optically coupled to the handpiece body 105 so that the light transmitted from the light generating unit can be incident on the core 115, It is possible to construct another type of optical transformer 110b capable of outputting the light of a certain wavelength (for example, a long period of lattice section).

As a result, the optical transformer 110b that emits light of a strip shape can be constructed by removing the jacket layer 117 of a predetermined interval in the optical fiber 114 so that the portion where the long period grating 115a is formed is exposed, In the case of the handpiece 100 having the optical transformer 110b composed of the optical fiber 114 of a flexible nature, the silin can be usefully used for treating a long and curved part including a dental field such as a treatment have.

The user holds the handpiece body 105 with one hand while holding the end of the optical fiber 114 with the opposite hand and uses the handpiece body with the other hand so that the user can hold the other end of the optical fiber 114 A handle 118 may be provided.

It is also preferable that one end of the optical fiber is detachably connected to the handpiece body 105 through the optical fiber connector mechanism 119 so that the optical fiber 114 can be replaced when necessary.

Since the light of a certain wavelength outputted from the light generating unit is transmitted through the optical fiber of the light transmitting unit 3, the optical fiber 114 having the long period grating 115a preferably uses the same optical fiber as the optical fiber of the light transmitting unit Do.

As described above, the handpiece of the present invention capable of irradiating light in the form of a line has been described with various embodiments, and the scope of rights of the present invention is not limited to the above-described embodiments, Various modifications and improvements of those skilled in the art using the basic concept of the present invention are also included in the scope of the present invention.
