Problems solved by technology

But it didn’t develop because of two reasons. One is that the scattering and absorption of human tissue makes the light entering the body very weak and difficult to focus.
The second is to choose a wavelength with better light transmission, and the thermal effect will be poor due to little absorption, which will not achieve the purpose of acupuncture and moxibustion.
If the optical fiber can be inserted and pulled out at will, the inner surface of the catheter needle is required to be polis

Embodiment 1

[0038] The medical optical needle of the present invention includes an optical fiber (3) and a stainless steel sleeve (1), the stainless steel sleeve (1) is located on the outer layer, the core is an optical fiber (3), and an adhesive (2) is filled between the optical fiber and the stainless steel tube ;Such as figure 2 shown. The external shape of the medical optical needle at the needle tip is similar to that of the disposable injection needle. figure 1 As shown, the existing medical injection needle with an outer diameter of 0.7 mm can be used, and the needle tip angle is 12 degrees. figure 2 and 3 shown.

[0039] Figure 4 It is the assembly diagram of the medical optical needle and the light output part of the optical fiber coupler. The coupling head 10 at the output end of the coupler contains the bare optical fiber 9, which has the function of positioning and collimating the bare optical fiber 9. The limit function of the metal protective sleeve 11 cooperates with...

Embodiment 2

[0041] The invention can be made into a portable medical light needle, which uses a light-emitting diode and a button battery as a light source, and uses red light, which can be used for acupuncture or aiming at thrombus to dissolve thrombus. The spectral band and power of the output light are controlled by the light-emitting diode itself, and the irradiation dose is controlled by the working time and the life of the battery. Such as Figure 5 A structure is shown, using ordinary red high-brightness light-emitting diodes. Small light-emitting diodes and button batteries are directly packed into the stainless steel casing 1 . Commercially available small LEDs are 3mm in diameter. But the chip size is only 0.24 mm. Directly use the chip to lead out the lead wire, and install the reflector at the bottom of the sleeve. When the sleeve is tightened, the diode is on, and at the same time, the focus is coupled into the optical fiber and then coupled into the medical light needle,...

Embodiment 3

[0043] The present invention can also achieve precision control of energy and monitoring of treatment effects, and the working principle is as follows: the optical needle plug of the medical optical needle is connected to an optical fiber jumper, and the other end of the jumper is connected to a one-to-two coupler 6, such as Figure 8 : One-to-two coupler 6 with three ports. Port one 15 is connected to the laser and is the light input port. Port 2 16 is an output port, which is directly coupled with the light needle, and then outputs light energy from the needle tip. The reflected light at the needle tip and the excited light and fluorescence will be collected and returned to the original path, and output from the port three 17 according to the principle of directional coupling, and the port three 17 is connected to the detector, and becomes an electrical signal for analysis and processing. The input light is a semiconductor laser with tunable optical wavelength, so the wavel...

Abstract

The invention discloses a plug and play medical optical needle, which is a medical optical needle for utilizing optical fiber technology to inject light energy into the body and capable of being used for diagnosis, acupuncture and treatment. The plug and play medical optical needle adopts the form of a syringe needle, has the design shape of the syringe needle, and is a solid needle provided with a composite structure; optical fibers are taken as a core; the optical needle is directly inserted into the body until reaching a focus site; the other end of the optical needle is manufactured into an optical needle plug for inserting into an optical fiber coupler; and the optical needle is inserted into the general optical fiber coupler, and acquires light energy from various tunable light sources or various wideband light sources including a semiconductor laser so as to realize injection of the light energy. Moreover, a beam-splitting coupler arranged can transmit treatment and diagnosis information to related detectors for diagnosis and analysis.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a plug-and-play medical optical needle which uses optical fiber technology to inject light energy into the body and can be used for diagnosis, acupuncture and treatment. Background technique [0002] The laser itself is a kind of energy, and the coherence and directionality are very good, the intensity can be very high, and the output wavelength and energy are precisely controllable. For example, the use of argon ion laser to irradiate blood through extracorporeal circulation can kill HIV; the characteristic lines of the laser spectrum can be used for diagnosis and to judge the therapeutic effect of drugs. Therefore, laser can be used not only for treatment, but also for diagnosis. Currently, lasers are already widely used in the treatment of skin diseases, or in near-surface medical applications, such as in ophthalmology and dentistry. However, it is very difficult for laser lig...
