Description

Medical device using laser and hand piece applied to the medical device

The present invention relates to a medical device using a laser, and more particularly to a medical device for treating the skin using a laser. The present invention also relates to a hand piece applied to the medical device using the laser, wherein the hand piece is vibrated, so that the optical fiber connected to the hand piece vibrates to increase the laser irradiation area in the body.

Recently, laser is widely used in the field of medical devices, one of which is the field of skin treatment.

A medical device using a laser may be applied to a fat removal procedure in which a tissue is removed, an abnormal tissue is destroyed, or an adipose tissue is removed by inserting the distal end portion of the optical fiber into the body and irradiating the laser light to the tissue.

On the other hand, skin treatment using a laser includes a method of removing spots and scars, skin lifting to promote skin regeneration, and the like. Skin treatment using such a laser is a method of irradiating the laser from the outside of the skin. Among them, skin lifting is a method of irritating the skin by irradiating the laser to stimulate the skin to promote cell growth, thereby regenerating the skin, improving whitening, or improving wrinkles, thereby giving elasticity to the skin. However, these conventional procedures are to irradiate the laser from outside the skin, not a method of directly irradiating the laser inside the skin, epidermis and epithelium where the proliferation of skin cells occurs.

On the other hand, liposuction is one example of a procedure for irradiating a laser into the skin. Liposuction is a rapidly growing field of plastic surgery that removes excess fat deposits in the human body. According to such liposuction, there is an advantage that it is easy to remove the fat of the area that is difficult to remove by exercise or diet. In addition, since exercise or diet, such as only reducing the size of fat cells may be thickened later in the fat layer, while liposuction reduces the number of fat cells has the advantage of the above and less problems.

As an example of such liposuction, a cannula having a thin pipe shape can be inserted into a fat layer and then moved back and forth to separate and destroy fat cells to inhale and remove fat. On the other hand, the liposuction apparatus has been proposed to improve the method to generate ultrasonic waves in the cannula to facilitate liposuction.

On the other hand, recently, there is a method of dissolving the fat layer by irradiating the fat layer in the body with a laser. An example of a method using such a laser is a method using an optical fiber. Specifically, the laser is irradiated to the fat layer by inserting the optical fiber into the fat layer and causing the laser to be emitted through the optical fiber.

However, in the case of laser irradiation through the optical fiber, since the irradiation angle of the irradiated laser is very narrow, when the laser is irradiated in a stationary state after the optical fiber is inserted into the fat layer, the laser irradiation surface is narrow and the efficiency of fat removal is very low. Therefore, for efficient fat irradiation, after inserting the optical fiber into the fat layer, the operator must move the optical fiber back and forth and left and right to widen the laser irradiation surface. Therefore, even in liposuction using a laser, there is a problem that still requires a lot of user power.

Figure 2 schematically shows an example of a medical device using a laser according to the present invention.

As shown in FIG. 2, a medical apparatus using a laser according to the present invention includes a laser generating means 100 for emitting a laser, and an optical fiber for transferring a laser generated by the laser generating means connected to the laser generating means 100. 300; And a hand piece 200 installed on the optical fiber. The hand piece 200 is spaced apart from the distal end of the optical fiber 300.

Referring to FIG. 2, the optical fiber 300 may be divided into two parts based on the hand piece 200. Specifically, since the end portion of the optical fiber around the hand piece 200 of the optical fiber is a portion that is inserted into the human body is separated into a human body insertion portion 310 separately. The human body insertion portion 310 also corresponds to an optical fiber. The optical fiber portion located opposite the human body insertion portion 310 is connected to the laser generating means.

The hand piece 200 is provided with vibration means 213 and 223, by which the hand piece vibrates by the vibration means (see FIGS. 3 and 5).

The laser generating means 100 is to emit a laser that can be used for the treatment of the tissue in the body, for example to emit a laser having a wavelength of 0.75 ~ 2.5㎛. The laser having the above range wavelength can be applied to human procedures without causing great harm to the human body. If necessary, a laser outside the wavelength range may be used.

In addition, the laser generating means 100 may be used to emit a pulsed laser having an energy level of 30 ~ 600 mjoule / pulse energy level. If the energy level is less than 30 mjoule / pulse, the laser energy is low, the procedure is not efficient, and if the energy level exceeds 600 mjoule / pulse, the laser energy is high, there is a risk of damaging the human body.

When the medical device using the laser according to the present invention is applied to skin lifting, the energy level may be limited to a range of 100 to 450 mjoule / pulse.

The laser generating means 100 may be used by employing a laser light source applied to the laser treatment device currently being used. For example, one of a ruby laser, an Alexandrite laser, a semiconductor laser, and an Nd: YAG laser may be selected and used based on the generated light source.

Those skilled in the art will be able to select and use a suitable laser as needed. It is a matter of course that other types of lasers may be used in addition to the above-mentioned types.

Outside the body of the laser generating means 100 to provide a control dial for the user to adjust the power and wavelength of the laser according to the need, including a switch for turning on and off the power to adjust the power and wavelength of the laser through this Can be.

The power of the irradiated laser affects the temperature produced in the skin tissue, and the wavelength determines the depth of penetration of the laser tissue into the skin tissue.

Therefore, the power and wavelength of the laser beam are determined according to the respective purposes of use, such as for the purpose of irradiating the laser, for excision of internal tissues, for the destruction of foreign substances such as gallstones, for removing fat, and for lifting the skin. You can choose.

The optical fiber 300 serves to deliver the laser emitted from the laser generating means 110.

The laser beam transmitted through the optical fiber is irradiated toward the irradiated object at the end of the optical fiber 300 to perform the procedure.

An example of a hand piece 200 applied to a medical device using a laser according to the present invention is the hand piece 210 disclosed in FIG. 3.

As shown in Figure 1, the hand piece 200 is spaced apart from the distal end of the optical fiber 300, which is a laser transport means. The optical fiber 300 may be divided into two parts based on the hand piece 200. That is, since the optical fiber is a part inserted into the human body from the optical fiber to the distal end portion of the optical fiber, the optical fiber located at the opposite side of the human body insertion part 310 is connected to the laser generating means. It is referred to as the optical fiber 300 as commonly referred to as the portion.

The human body insertion part 310 may be configured to be replaced after the procedure.

As shown in Figure 3, the medical device hand piece 210, body 211; Optical fiber fixing means (212) formed in a portion of the body; Vibration means (213) formed on the other part of the body; And power supply means 214 for supplying power to the vibration means.

In addition, the medical device hand piece 210 may further include a cover 217.

As seen in the hand piece for medical devices according to FIG. 3, the optical fiber is fixed to the hand piece 210 by means of optical fiber fixing means 212. Thus, in the present invention, a portion of the optical fiber from the optical fiber fixing means 212 to the end of the optical fiber is separately classified as a human body insertion part 310. In FIG. 3, the optical fiber fixing means 212 is disposed on both sides of the body 211.

Specifically, since the optical fiber portion extending from the optical fiber fixing means 212 disposed outside the body to the end is inserted into the human body, this portion becomes the human body insertion portion 310.

According to an example of the present invention, the optical fiber connecting means 215 may be disposed adjacent to the optical fiber fixing means 212. 3, an optical fiber connecting means 215 is disclosed, which is disposed between two optical fiber fixing means 212.

Different optical fibers may be connected by the optical fiber connecting means 215, and the optical fiber 310 corresponding to the human body insertion part of the optical fiber may be replaced by using the optical fiber connecting means. That is, once the procedure is over, the human body insertion part 310, which is a part of the optical fiber that has been inserted into the human body, may be discarded and replaced with a new human body insertion part 310.

The optical fiber connecting means 215 is disposed adjacent to the optical fiber fixing means 212, and since the optical fiber can be replaced through the optical fiber connecting means, it extends from the optical fiber connecting means 215 to the optical fiber ends. It will also be possible to distinguish the portion of the human body insertion portion (310).

The optical fiber connecting means 215 is configured so as not to interfere with the laser transfer. Even if the optical fiber is connected through the optical fiber connecting means 215, the optical fiber connecting means 215 has a structure capable of laser transfer so as to have continuity in the transfer of the laser through the optical fiber. The optical fiber connecting means 215 may be a product already developed or a commercially available product.

The hand piece 210 for the medical device vibrates by the vibration of the vibrating means 213. The optical fiber is also vibrated by the vibration of the hand piece 210, in particular the human body insertion portion 310 is vibrated. When the human body insertion part 310 is connected to the hand piece 210, the hand piece 210 becomes a fixed end and the distal end of the human body insertion part 310 becomes a free end, due to the vibration of the fixed end. The free end may have the same effect as vibrating.

The vibration generated from the hand piece 210 may be, for example, a vibration similar to that of a mobile phone vibration, whereby the distal end portion of the human body insertion portion 310 is proportional to the length of the human body insertion portion 310. Vibration with amplitude That is, the distal end portion of the human body insertion portion 310 may vibrate with an amplitude of several mm to several cm by vibration generated from the hand piece 210.

As a result, the irradiation area of the laser irradiated through the distal end portion of the human body insertion portion 310 can be expanded.

Conventionally, after inserting an optical fiber into the body tissue, the operator reciprocates while moving the optical fiber back and forth and left and right so that the laser irradiated from the end of the optical fiber is irradiated to a large area, when using the handpiece according to the present invention It is possible to extend the irradiation range of the laser irradiated to the tissue in the body without the same effort. Therefore, the physical labor of the operator can be reduced and the efficiency of the procedure can be improved.

The frequency of the vibration means 213 is to be in the range of 60 ~ 600Hz. Of course, it may include means for adjusting the frequency of the vibration means.

When vibrating in the frequency range as described above, the vibration width of the human body insertion part 310 connected to the vibration of the hand piece 210 may be maximized. The vibration width may vary depending on the thickness and length of the optical fiber and the frequency of the vibration means. Those skilled in the art may optimally select the vibration width of the human body insertion part 310 by adjusting the frequency.

According to an example of the present invention, a vibration motor or an actuator may be used as the vibration means 213. When using the vibration motor or the actuator as a vibration means it is possible to adjust the frequency of the vibration means by adjusting the current.

As an example of the vibration motor, as shown in FIG. 6, a vibration motor 213 having a structure in which the balance weight 530 is eccentrically coupled to the rotating shaft 520 installed in the fixing part 510 may be used. Specifically, in the vibration motor 213 shown in FIG. 6, the balance weight 530 eccentrically coupled to the rotation shaft 520 is eccentrically coupled to each other so that a heavy balance weight is formed on one side of the rotation shaft 520. 530 is attached to the rotating shaft to rotate. As a result, vibration is caused because the rotating shaft 520 rotates in an unbalanced state. As an example of the conventional use of such a vibrating motor, there is a silent call means in a mobile phone or a mobile communication device. The vibration motor may be classified into a rod type and a coin type. Recently, a coin type is widely used.

Meanwhile, as another example of the vibration means, an actuator having a structure in which a vibrator or a vibration plate flows according to the frequency input signal strength may be used.

The medical device handpiece 210 shown in FIG. 3 is not provided with a separate power source, and the power source is disposed outside the handpiece 210 and is provided by a power supply means 214 installed in the handpiece. Vibration means 213 is connected to a power source (not shown). In this case, the power source may be a domestic or industrial AC power source, and the power supply unit 214 may be a transformer or an electric wire. Those skilled in the art will be able to easily connect the power source to the vibration means 213.

According to an example of the present invention, a cannula 400 may be provided to protect the human insertion portion 310. The optical fiber portion corresponding to the human body insertion portion 310 may be disposed inside the cannula 400 to prevent the human body insertion portion 310 from being unnecessarily bent or damaged. In addition, by applying the cannula 400 formed of a metal or other hard material, the human body insertion portion 310 can be easily inserted into the human body. The cannula and the optical fiber (human body insertion part) also vibrate together by the vibration of the vibration means 213.

4 shows an example of such a cannula 400. The distal end of the cannula 400 may be opened to expose an end portion of the optical fiber corresponding to the human insertion part 310 through the open portion so that the laser is irradiated.

A slope may be formed at the distal end of the cannula 400. At this time, the inclination formed on the distal end of the cannula 400 may be such that the inclination angle (θ) is in the range of 30 ~ 60 °. If the inclination angle θ is too small, the edge of the cannula 400 may be damaged and unnecessary damage may be caused to the human body. If the inclination angle is too large, the end of the cannula may be blunted and the penetration into the human body may not be easy. Can be. The inclination formed at the distal end of the cannula 400 is to limit the angle to the range of 30 ~ 60 °.

According to an example of the present invention, a groove 410 may be formed on the side surface of the cannula 400. Through the grooves can be removed by inhaling body fluids or fat generated during the procedure.

In FIG. 4, the outer diameter of the cannula may vary depending on the diameter of the optical fiber corresponding to the human insertion portion 310. In general, the diameter of the optical fiber is less than 2mm, the outer diameter of the cannula can be adjusted to about 1 ~ 2mm. As the diameter of the optical fiber is larger, the outer diameter of the cannula may also be larger.

The length of the cannula may vary depending on the needs of the operator, and considering the vibration efficiency and the durability or strength of the optical fiber, it is appropriate to set it to about 10 to 25 cm.

According to an example of the present invention, the end of the optical fiber may be protruded by 1 ~ 2mm from the distal end of the cannula. The optical fiber protrudes out of the cannula so that laser irradiation is not disturbed by the cannula.
