Description

Light-conducting composite tube

The invention relates to a tube body of a light-conducting composite material, in particular to a tube body which is composed of an optical fiber.

When the light is not known, when the pipe is used to suck or discharge the object, the difficulty of the operation is often increased due to insufficient light.

For example, when the dentist performs an intraoral operation, the blood flowing out of the wound is mixed with the saliva, and accumulates in the oral cavity, which easily causes obstruction of the line of sight and affects the operation of the operation. Therefore, it is necessary to use an extraction device. At the same time as the operation, blood and saliva are taken up by a tube connected to the extraction device.

However, the mouth can be opened to a limited extent, coupled with the construction of the teeth, so that there are still many dark places in the mouth, the doctor can only turn the patient's head to make the light shine, to confirm the accumulation of blood and saliva, for Patients or doctors are quite inconvenient.

In addition, some invasive treatments will have the same problems, such as endoscopes, gastroscopes, colonoscopy, etc., all need to add a light source to the outer edge of the tube, in the case of invasive treatment, if The larger the volume of the incoming tube, the more uncomfortable the patient is. Moreover, the light source protrudes from the tube body, thereby increasing the weight of the front end of the tube body, which makes the movement of the tube body difficult.

In view of the above problems, the present invention provides a light-conducting composite pipe body which is directly fabricated by using an optical fiber and a plastic composite to form a pipe body, so that light can be entered from one end of the pipe body, and then from the other end of the pipe body. The injection does not need to add a separate illuminator at the front end, so the weight does not concentrate on one end of the tube body, and there is no need to deliberately evade the protruding illuminant in the manipulation. Furthermore, the light directly illuminates the tube body from the front of the tube body. In front, it has the best lighting effect and is easy to control and master.

The invention includes a plurality of optical fibers and a plastic, wherein each of the optical fibers includes an optical output end and an optical input end, and the light is emitted from the light output end after being incident from the light incident end; the plastic system is composited Side edges of the optical fibers to fix the relative positions of the optical fibers and form a tubular shape, and are defined as a fiber-optic composite plastic light pipe, the optical fiber composite plastic light pipe includes a light pipe mouth and a light pipe port, and the The light-emitting ends are arranged along the light-emitting nozzle and facing the outlet of the light-emitting tube.

Since the present invention does not increase the illuminant outside the conventional tube, it can be directly fabricated into a desired thickness or shape for ease of operation. Moreover, the present invention can be applied to an endoscope, a dental operation, or a maintenance assembly of a machine tool, and has a wide application field.

In view of the above advantages, in order to enable the reviewing committee to further understand the present invention, a preferred embodiment is disclosed as follows.

Furthermore, the embodiment of the present invention does not need to hang the illumination source at the outer edge, so the weight is not concentrated on one end of the tube body, and the illuminating body does not need to be deliberately evaded in the manipulation, thereby greatly improving the convenience of operation. If it is used for invasive treatment, it is only necessary to open an entrance close to the diameter of the tube in the human body, and the wound caused by the embodiment of the present invention is smaller than that of the inlet provided by the external light source.

Referring to FIG. 2, FIG. 3 and FIG. 5, the light-injecting ends 12 can be further concentrated on one portion of the light-injecting nozzle 32, and each of the light-injecting ends 12 is directed toward the entrance. Outside the light pipe port 32, the light-injecting ends 12 can be simultaneously illuminated by using a single light source. In the embodiment of the present invention, a handle H is inserted into the handle H. An illumination source L and a conductive medium T are disposed in the handle H. One end of the conductive medium T abuts the illumination source L, and the other end depends on The light emitted from the light source L is re-entered into the light inlet port 32 via the conductive medium T, so that the light exiting ends 11 can emit light. Further, in the plastic 20 which is not composited with the optical fibers 10 (i.e., the regions S shown in Figs. 2 and 5), vermiculite, zircon or fibers (not shown) are added to increase the area S. strength.

Since the light incident ends 12 are concentrated in one place, only one light source L is required to inject light into the light incident ends 12, thereby reducing the required electric energy and the number of the light sources L. In addition, the non-essential component of the conductive medium T may directly be disposed near the light-incident end 12 to allow light to directly enter the optical fibers 10.

Referring to FIG. 7 and FIG. 8 , the light-incident end 12 can be further arranged along the light-injecting tube port 32 , and each of the light-injecting ends 12 is directed outward of the light-injecting tube 32 , thereby being In combination with more illuminating sources, in order to meet different situations, for example, another illuminating source L' shown in FIG. 9 corresponds to the arrangement of the light-incident end 12 as shown in FIG. A circular arrangement is provided whereby each of the light incident ends 12 is illuminated by light.
