Abstract

PURPOSE: To provide an inexpensive and safe laser knife tip by forming the tip into non-hollow type using a sodium chloride crystal, regarding a laser knife tip mounted on the tip end of a handpiece and designed to receive a laser 'beam at one end and emit the beam from the other end. CONSTITUTION: A laser knife tip 1 is formed to be non-hollow type, using a sodium chloride crystal harmless to a human body, and a large diameter section thereof is mounted on a handpiece 2. Also, a laser beam is emitted from a small diameter section of the tapered end. Furthermore, an articulated manipulator or a fiber cable is connected to the joint section 3 of the handpiece 2. A laser beam is introduced into the handpiece 2, and received with the large diameter section of the tip 1. Then, the laser beam is emitted from the small diameter section of the tapered end. As a result, a soot generated at the time of irradiating the laser beam does not enter a hollow section, and irradiation efficiency for the laser beam can be improved, accelerated by Fx high laser beam transmission efficiency of the sodium chloride crystal itself.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser scalpel tip used for incision, excision, transpiration, coagulation and the like in medical, dental and other fields.

[0002]

2. Description of the Related Art Most conventional laser scalpel chips mounted on the tip of a handpiece have a tapered hollow shape as shown in FIG. The large-diameter portion 5 of this laser knife chip is attached to the handpiece 2, and the large-diameter portion 5 receives the laser light and the small-diameter portion 6 emits the laser light.

[0003]

However, when the conventional hollow laser scalpel tip is used, the oil output generated when the laser beam is irradiated enters the inside of the hollow to significantly reduce the output of the laser. There is. Further, when the laser scalpel tip is used in contact with biological tissue, foreign matter adheres to the portion and is likely to be clogged, and there is a problem that cleaning and sterilization must be performed after each treatment. In this case, it is uneconomical because it is expensive even if it is desired to dispose the laser scalpel chip, and therefore an inexpensive laser scalpel chip is being demanded.

Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide an inexpensive and safe laser scalpel chip.

[0005]

In order to achieve the above object, the present invention provides a handpiece for treatment using a laser beam in medical or dental care, which is attached to the tip of the handpiece, and A laser scalpel chip that receives laser light at one end and emits the laser light at the other end is made of sodium chloride crystal, and is formed non-hollow.

[0006]

According to the present invention, the sodium chloride crystal is used as a thin plate attached to a portion for emitting laser light in the invention disclosed in Japanese Patent Laid-Open No. 5-95960, and the transmittance of laser light is Is known to be a high material, but in the present invention, by forming a non-hollow laser knife tip using this sodium chloride crystal, oil smoke enters inside like a conventional hollow laser knife tip. Since it can be manufactured in a harmless manner at low cost and at a low cost, it can be disposable.

[0007]

Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a view showing a state in which a laser knife chip according to an embodiment of the present invention is attached to a handpiece.

The laser scalpel tip 1 shown in the figure is made non-hollow by using a sodium chloride crystal harmless to the human body. In this embodiment, the large diameter portion 5 side of the laser scalpel tip 1 is attached to the handpiece 2. Then, the laser beam is emitted from the tip small diameter portion 6 formed in a tapered shape. An unillustrated articulated manipulator or fiber cable is connected to the connecting portion 3 of the handpiece 2.

In this structure, laser light is introduced into the handpiece 2 from an articulating manipulator or a fiber cable connected to the connecting portion 3 of the handpiece 2.
The large-diameter portion 5 of the laser knife chip 1 receives the laser light, and the small-diameter portion 6 at the tip emits the laser light.

In this case, since the laser knife tip 1 is made non-hollow with only sodium chloride crystals, oily smoke generated at the time of laser light irradiation does not enter the inside of the hollow as in the case of conventional hollow formation. In addition to the fact that the sodium chloride crystal itself has a high laser light transmission efficiency, the irradiation efficiency of the laser light can be improved, and treatment can be performed either in contact or in non-contact. Furthermore, if it is sterilized during the manufacturing process and sealed, the sterilization process before use becomes unnecessary, and since it is harmless to the human body and inexpensive, it can be disposable. Therefore, sterilization treatment after use is unnecessary. Although the laser knife tip 1 is formed in a tapered shape in this embodiment, it can be formed in various shapes depending on the application.

[0011]

EFFECTS OF THE INVENTION According to the present invention, since the laser knife tip is made non-hollow with only sodium chloride crystals, oil smoke generated during treatment does not affect the irradiation of laser light, and the irradiation efficiency of laser light is improved. It is possible to increase the contact resistance and to treat it by contact or non-contact. As a result, the surgical procedure is not restricted and a high therapeutic effect can be obtained. Further, the laser scalpel chip is harmless to the human body and can be manufactured at low cost, so that it can be disposable, and even if it is thrown away, no pollution is caused, so that it can be easily discarded.

Claims (1)

[Claims] 1. In a handpiece for medical treatment using laser light in medical treatment or dentistry, the handpiece is attached to the tip of the handpiece, one end of which receives the laser light and the other end thereof receives the laser light. A laser scalpel tip for emitting a laser is formed in a non-hollow structure with sodium chloride crystals.
