Micro-nano waveguide type laser needle device

Abstract

The invention discloses a micro-nano waveguide type laser needle device, which comprises an acupuncture needle and a laser input mechanism. The laser input mechanism comprises a laser light emitter and a transmission light path; a light guiding pore canal extending from a needlepoint to a needle handle is arranged in the acupuncture needle; the pore diameter of the light guiding pore canal is less than 50 micrometres; a light source port used for connecting with the transmission light path is arranged on the needle handle; the light source port communicates with the light guiding pore canal. The micro-nano waveguide type laser needle device transmits laser to the needlepoint of the acupuncture needle through the micro-nano type light guiding pore canal, and deeply penetrates into a human body by utilizing the inserting function of the acupuncture needle and realizes the irradiation effect on deep points; compared with the prior art, the acupuncture needle can work in a finer manner because optical fiber is not implanted in the light guiding pore canal, thereby not only being used for laser probing, but also realizing multiple functions such as common acupuncture, laser acupuncture, the adapting with electro-stimulation, etc.

Description

technical field [0001] The invention relates to a medical device, in particular to a micro-nano waveguide type laser needle device, which can transmit laser light to the needle point and enter the human body to irradiate the deep acupuncture points of the human body. Background technique [0002] At present, the transmission structure used to transmit laser light to animals and plants is: the laser source is transmitted directly through optical fibers. One of its uses is to use optical fibers for detection. For example, when measuring blood flow, first insert the laser needle at the corresponding position Then insert the optical fiber into the laser needle, but the optical fiber has no cutting function, and the built-in optical fiber of the laser needle will be relatively thick, and the optical fiber may be broken during the insertion process, which will cause great harm to the human body. [0003] In addition, the above-mentioned laser transmission structure can also realiz...

Problems solved by technology

[0002] At present, the transmission structure used to transmit laser light to animals and plants is: the laser source is transmitted directly through optical fibers. One of its uses is to use optical fibers for detection. For example, when measuring blood flow, first insert the laser needle at the corresponding position Then insert the optical fiber into the laser needle, but the optical fiber has no cutting function, and the built-in optical fiber of the laser needle will be relatively thick, and the optical fiber may be broken during the insertion process, which will cause great harm to the human body

[0003] In addition, the above-mentioned laser transmission structure can also realize the purpose of acupuncture and moxibustion on the human body. Traditional acupuncture uses rigid needles or silver needles for acupuncture, and uses electro-acupuncture instruments for treatment, but the function of traditional acupuncture and moxibustion can only be acupuncture. Deqi, that is, it only stimulates the acupuncture points, and the electroacupuncture instrument is mainly for electrical stimulation, and has no moxibustion effect

The current laser acupuncture therapy generally places the optical fiber outside the human epidermis to irradiate the corresponding acupoints. The disadvantage is that the laser attenuates greatly during the process of penetrating the skin and tissue, and often requires a relatively high-power laser input mechanism. , leading to an increase in the cost of medical equipment, and when using a low-power laser input mechanism, because part of the laser light is reflected by the skin and the other part is refracted, when the absorbed part of the laser light penetrates through a depth of 2 mm, its power will be attenuated by 90%. Therefore, it is impossible to form "light needles" at all, and it cannot play the role of acupuncture and moxibustion.

China ZL200620126846.0 discloses a disposable acupuncture device, which guides the optical fiber into the needle core and connects it with a laser machine for optical acupuncture. Since the needle core has a complete optical fiber structure, the needle is relatively thick, which will increase the number of acupuncture needles. The movement resistance of the needle is relatively large when the needle is inserted, and the adhesion phenomenon between the acupuncture needle and the skin and muscle will occur when the needle is pulled out, and the pain of the patient is relatively obvious; in addition, China ZL96102788.6 discloses a compound laser machine. The laser machine is limited to the irradiation of the human body surface, and cannot irradiate deep acupoints through its light guide system, so the scope of treatment is extremely limited
