permanent magnets

241 and 242 are formed.

As shown in FIG. 2, the laser output hole 201 penetrates the rotation probe 240 to a part of the rotation probe 240 corresponding to the outer case of the treatment unit 2.

Due to this laser output hole 201, when the treatment unit 2 is inserted into the vagina of the laser treatment subject, a part of the end of the treatment unit 2 is opened and the laser transmitted from the body unit 1 is the laser. Through the output hole 201 is irradiated to the desired portion.

The fixed probe 210 is fixedly connected to a stage at which the laser is output from the body portion 1, is connected to the optical path of the laser formed in the body portion 1, and has an internal space in which the optical path of the laser is extended. An end not connected with (1) has an open cylindrical shape.

The reflective mirror 220 is connected to an open end of the rotating probe 240 in which the laser output hole 201 is formed, and is inclined in the open end direction of the fixed probe 210 so that the bottom of the reflective mirror 220 is fixed to the fixed probe ( The laser beam is output to the laser output hole 201 by reflecting the laser beam passing through the internal space of the fixed probe 210 by descending toward the open end direction of the 210 to face the laser output hole 201.

The reflection mirror 220 is connected to the rotation probe 240 in which the laser output hole 201 is formed to be driven to rotate like the rotation of the rotation probe 240.

As a result, the reflection mirror 220 does not change in the angle at which the laser output hole 201 is viewed.

The treatment part 2 is located inside the fixed probe 210 at the position where the reflection mirror 220 and the fixed probe 210 are adjacent to each other, that is, the furthest position from the laser output hole 201 among the open ends of the fixed probe 210. The surface further includes an image sensor 281 and an illumination unit 282 facing the laser output hole 201 direction A. FIG.

In addition, the image sensor 281 outputs an image signal of an image exposed through the laser output hole 201 and is formed at a position at which the open end of the fixed probe 210 is exposed to the laser output hole 201. Rather than taking a closed portion without forming a), an image of the outside of the treatment unit 2 may be photographed through the laser output hole 201.

The image sensor 281 outputs an image signal of a portion of the inner wall of the vagina to which the laser is irradiated, thereby visually confirming a desired state of the vaginal portion, so that a user such as a doctor may visually check the state of the treatment portion.

In addition, the lighting unit 282 assists an operation of acquiring an image signal by the image sensor 281, and irradiates light to a portion exposed through the laser output hole 201 positioned in the fixed probe 210. This is to improve the image quality of the image signal obtained by irradiating light to the inner part of the obtained quality.

The lighting unit 282 may be formed of at least one light emitting diode (LED), but is not limited thereto.

Referring to FIG. 3, the fixed probe 210 includes a signal line 283 on the inner surface of the image sensor 280 as described above, which transmits an image signal or supplies power for driving the lighting unit 282. Or to form a space inside the thickness of the fixed probe 210 to pass through the space.

The installation unit 230 extends in a vertical direction in a direction in which the fixed probe 210 is formed on a side of the side of the fixed probe 210 connected to the body portion 1.

The installation unit 230 has a position to allow the outer surface of the rotation probe 240 to be vertically formed as the installation unit 230 after having a length equal to the length of the vaginal length of the examinee undergoing laser treatment.

The two

electromagnets

231 and 232 are installed in the installation unit 230 with a space therebetween.

In this case, the

electromagnets

231 and 232 are divided into a fixed electromagnet 231 formed closer to the fixed probe 210 and a rotating electromagnet 232 formed closer to the rotation probe 240.

The fixed electromagnet 231 and the rotating electromagnet 232 will be described below together with the

permanent magnet portions

241 and 242.

The rotary probe 240 is formed to surround the outside of the fixed probe 210 at a distance from the fixed probe 210.

The surface surrounding the front end of the installation unit 230 of the outer surface of the rotary probe 240 is inserted into the vagina of the laser irradiated, and abuts the inner wall of the vagina.

At least one bearing 250 may be provided between the rotation probe 240 and the fixed probe 210 to assist the rotation probe 240 in rotation.

At this time, the bearing 250 is located on the inner surface of the rotary probe 240 of the rotatable probe 240 to enter the vagina of the laser irradiation.

Referring to FIG. 4, the

permanent magnets

241 and 242 are formed at positions facing the front surface of the rotating probe 240 among the outer surfaces of the fixed electromagnet 231, and the rotation of the rotating probe 240 is performed. It is formed corresponding to all positions that change the position facing each other, and the fixed probe of the inner surface of the rotating probe 240 adjacent to the fixed magnet portion 241 and the rotating electromagnet 232, the alternating magnets of the N pole and the S pole is formed The magnets of the N pole and the S pole are alternately formed on the entire inner surface horizontal to the formation direction of the 210 and the rotating magnet part 242.

The rotating magnet part 242 of the present embodiment is formed in the shape of a donut with the fixed probe 210 inserted in the center thereof.

When a current flows through the fixed electromagnet 231, the fixed magnet unit 241 is brought into contact by the magnetic force of the fixed electromagnet 231, so that the distance d between the fixed magnet unit 241 and the fixed electromagnet 231 is zero.

At this time, the installation unit 230 is formed of a material or thickness that does not affect the magnetic force so that the fixed electromagnet 231 is in a magnetized state and attached by the fixed magnet portion 241 and the magnetic force.

In this configuration, when rotation driving of the rotation probe 240 is not required, the rotation probe 240 is fixed by putting a current into the fixed electromagnet 231.

The rotating magnet part 242 has a rotating electromagnet 242 when the current flows through the rotating electromagnet 232, and the magnetic poles N and S, which are the components of the rotating magnet part 242, are alternately formed. The rotating probe 240 connected to the rotating magnet part 242 is driven to rotate by the magnetic force of the 242 and the rotating electromagnet 232.

Through the rotational drive, the laser outputs through the laser output hole 201 toward the end side of the treatment part 2, that is, the rotary probe 240, instead of irradiating only one surface of the inner wall of the vagina with the laser. The laser can be irradiated 360 degrees in all directions.

The treatment unit 2 configured as described above is a ventilating unit for discharging the gas generated during the treatment of the vaginal wall by irradiating a laser from the inside of the treatment unit 2 to the rear end of the treatment unit 2 toward the body 1. 260 and the gas discharge hole 270 is further included.

Ventilation unit 260 is located in the body portion 1 direction of the installation unit 230, that is, the rear end of the installation unit 230, is located on the waterline and the installation unit 230, the gas discharge hole 270 is A hole is formed in the rotation probe 240 surrounding the rear end of the ventilation unit 260.

At this time, the gas discharge hole 270 is located in the rotary probe 240 adjacent to the ventilation unit 260 to discharge the gas pushed to the rear end through the ventilation unit 260 to the outside.

The gas discharge hole 270 is connected to a medical laser handpiece and a separate tube (not shown), and transfers the gas discharged to the gas processing unit (not shown) through the gas discharge hole 270 to the outside. Help move around.

The ventilator 260 and the gas discharge hole 270 are formed inside the fixed probe 210 and the rotary probe 240 when the gas formed by laser treatment of the vaginal wall at the end of the treatment unit 2 enters the inside of the fixed probe 210 and the rotary probe 240. By removing the outside of the treatment unit (2), the gas is filled to reduce the operation of removing the gas to take out the treatment unit (2) from the inside of the vagina to remove the gas.

Next, with reference to FIG. 5, the structure of the control unit for controlling the operation of the medical laser handpiece 1000 having such a structure will be described. This control unit also forms part of the medical laser handpiece 1000.

The control unit of the medical laser handpiece 1000 is connected to the electromagnet driver 4 connected to the fixed electromagnet 231 and the rotating electromagnet 232, the controller 101 connected to the electromagnet driver 4, and the controller 101. The image sensor 281 for generating and outputting an image signal for a desired portion, the lighting unit 282 connected to the control unit 101, and the image sensor 281 connected to the control unit 101 to receive and display an image captured by the image sensor 281. The display part 5 is provided.

The electromagnet driver 4 changes the operating state in response to the control signal of the controller 101 to transmit current to the fixed electromagnet 231 or the rotating electromagnet 232.

For this reason, the state of the

electromagnets

231 and 232 which received electric current from the electromagnet drive part 4 changes from the nonmagnetic state which is an initial state to the magnetization state which is a drive state.

When the state of the fixed electromagnet 231 is changed to a magnetized state by the operation of the electromagnet driver 4, the rotating probe 240 of the treatment unit 2 rotates in contact with the adjacent fixed magnet unit 241. It remains fixed.

On the other hand, when the state of the rotating electromagnet 232 is changed to a magnetized state by the operation of the electromagnet drive unit 4, by the magnetic action of the rotating magnet portion 242, the N pole and the S pole are alternately formed, the treatment unit (2) Rotation probe 240 is in a rotation state.

The controller 101 outputs a driving signal to the electromagnet driver 4 to change the state of the fixed electromagnet 231 or the rotating electromagnet 232 to a magnetized state at a desired time, thereby controlling the rotation operation of the rotating probe.

As described above, the image sensor 281 is connected to the treatment unit 2 to obtain an image signal corresponding to the inner wall of the vagina irradiated with the laser, and outputs it to the control unit 101.

Accordingly, the controller 101 processes the image signal input from the image sensor 281 to output the image obtained by the image sensor 281 to the display unit 5.

In addition, the controller 101 outputs a driving signal to the lighting unit 282 to provide illumination to a portion photographed by the image sensor 208.

The display unit 5 is installed outside the medical laser hand feed 1000 at a position where a user can easily check an image acquired by the image sensor 281.

Therefore, the display unit 5 outputs an image corresponding to the processed image signal output from the control unit 101. The display unit 5 may be formed of a liquid crystal display or the like.

The medical laser handpiece 1000 according to the embodiment of the present invention configured as described above is operated as follows by the control unit described with reference to FIG. 5.

First, the laser generator 3 is turned on to switch to a state in which the laser generator 3 can generate a laser.

Thereafter, the medical laser handpiece 1000 is turned on through the start switch provided in the trunk 1 to make the operation standby.

At this time, the control unit 101 is fixed to the electromagnet drive unit 4 by inputting a switch for controlling the electromagnet drive unit 4 among the function switches provided in the trunk portion 1 so that the rotation probe 240 is fixed without rotation. A signal for applying a current to the electromagnet 231 is output.

Fixed electromagnet 231 transmitted from the control unit 101 The electromagnet driving unit 4 receives the current applied to the fixed electromagnet 231 so that the fixed electromagnet 231 is in a magnetized state.

The fixed electromagnet 231 which is in the magnetized state is brought into contact with the adjacent fixed magnet part 241 by its magnetism to fix the rotation probe 240.

Thereafter, when the user is in the state of inserting the treatment unit 2 into the vagina of the examinee for treatment, an image sensor photographing the image of the outside of the treatment unit 2, that is, the inner wall of the vagina through the open laser output hole 201. In operation 281, the captured image signal is transmitted to the controller 101.

The controller 101 receiving the captured image signal outputs an image to the display unit 5 outside the medical laser handpiece 1000 so that the user visually checks the inside of the vagina.

When the user identifies the lesion to be treated through the display unit 5 inside the vagina, a laser output switch for outputting the laser transmitted from the laser generator 3 among the switches of the body 1 from the treatment unit 2 ( Not shown) to transmit the laser output command signal to the control unit 101.

The controller 101 receiving the laser output command signal outputs a laser from the body 1 to the treatment unit 2.

The laser output into the fixed probe 210 of the treatment unit 2 moves to the reflective mirror 220 positioned at the open end of the fixed probe 210, and then the optical path is changed by the reflective mirror 220 so that the laser Through the output hole 201 is irradiated to the outside of the medical laser handpiece 1000.

At this time, if the user wants to irradiate in a forward direction instead of a part of the inner wall of the vagina, the user inputs a switch of the body part 1 and transmits a signal for commanding electric power to the rotating electromagnet 232 to the electromagnet driver 4. .

The electromagnet driving unit 4 that receives the rotation electromagnet 232 current application signal transmitted from the controller 101 applies a current to the rotation electromagnet 232 so that the rotation electromagnet 232 is in a magnetized state.

The rotating electromagnet 232 which is in the magnetized state is rotated by the magnetic pole of the rotating probe 240 by the alternating poles of the rotating magnet part 242 formed on the inner circumferential surface of the upper position of the rotating electromagnet 232 among the inner circumferential surfaces of the rotating probe 240. Repeatedly pulling and pushing) rotates the rotary probe 240.

Fixing or rotating the rotation probe 240 may be changed through a switch of the body part 1 according to a user's selection while treating the inner surface of the vagina.

Next, a medical laser handpiece according to another embodiment of the present invention will be described with reference to FIG. 6.

Compared with the medical laser handpiece shown in Figs. 1 to 4, the components having the same configuration and performing the same function are given the same reference numerals as the medical laser handpiece shown in Figs. Description is omitted.

In the medical laser handpiece illustrated in FIG. 6, the rotary probe 240 surrounding the rear end of the ventilator 260 described with reference to FIG. 2 is formed without being wrapped around the rear end of the ventilator 260, and the ventilator ( The gas discharge hole 270 positioned at the rear end of the unit 260 is omitted. As described above, the gas discharge hole 270 has the same structure as the medical laser handpiece shown in FIGS. 1 to 4.

As such, when the structure blocking the rear end of the ventilation unit 260 and the gas discharge hole 270 are omitted, the gas is immediately discharged to the outside through the ventilation unit 260.

In this case, as described above, the structure of the rotary probe 240 which blocks the rear end of the ventilation unit 260 and a separate process such as a gas processing unit or a tube for processing the gas output when the gas discharge hole 270 is omitted are omitted. There is no need to provide a device, thereby reducing the manufacturing time and manufacturing cost of the medical laser handpiece of this embodiment.

The control unit for controlling the medical laser handpiece of FIG. 6 having such a structure is the same as that already described with reference to FIG. 5, and thus description thereof will be omitted. The medical laser handpiece formed as described above according to each embodiment is omitted. The laser procedure can be used to selectively select the desired depth, and the laser beam can be circumferentially irradiated to the inner wall of the vagina while sequentially changing the depth from the deep to the shallow part.

Referring to FIG. 7, the treatment of the vaginal inner wall 300 through the medical laser handpiece described above is automatically rotated by the treatment unit 2 having the reflection mirror and the laser is irradiated to the inner wall of the vaginal wall 300. Since the laser is irradiated 301 to the columnar BB, the discomfort and procedure time caused by the user's manual rotation are reduced, and only the rotation probe 240 of the treatment unit 2 equipped with the reflection mirror rotates. There is no fear of problems such as twisting of the wiring cable due to the rotation as shown in FIG.
