The present invention relates to a medical suction device having an illumination function and a disposable suction tip for use in the device. In particular, the present invention relates to a suction device having an illumination function for securing a field of view in a dark and narrow surgical position as a device for use in surgery and medical treatment, and a disposable suction tip for use in the device.

In order to remove blood, sap, pus, and other debris from a patient during medical treatment and surgery, a suction device is provided in the operating room by suction and removal using a vacuum principle. In general, since the site to be treated is very narrow and is often covered by surrounding tissues, it is difficult to accurately observe the suction site using only the lighting device of the procedure table, and thus there are many inconveniences in using a conventional suction device. To improve this, a device for directly illuminating a narrow surgical site is disclosed by other inventors in patent applications 2003-0036965 and patent applications 2004-0042541. Such an optical suction device is already disclosed and registered, and a detailed description thereof will be omitted.

In addition, since the size of the light output part basically occupies a volume, the suction part and the light output part must be injected into the treatment part together, which may damage other tissues or organs around the treatment part. In addition, the shape and size of the suction tip is usually varied according to the surgical site, it is not easy to configure the light exit according to this, it provides a light output that can be commonly used in various surgical conditions There is a lack of specific proposals for this, and its application to actual surgical sites is extremely limited.

Accordingly, it is an object of the present invention to provide a suction tip composed of a light emitting part and a suction part integrally. In addition, another object of the present invention is to provide a suction tip using a light emitting unit and a suction unit and a suction device using the suction tip. Another object of the present invention is to provide a suction device that provides an illumination function and a disposable suction tip for use in the suction device. In addition, an object of the present invention is to provide a suction device using the suction tip and the disposable suction tip having a lighting function, while maintaining the shape and size conditions of the suction unit variously depending on the surgical site.

In order to overcome the problems of the prior art, and to achieve the object of the present invention, the present invention includes a suction tip including a tubular body that is a photo-transmission medium and a total reflection layer applied to the outer peripheral surface of the body; A suction tube including an inner tube connected to the inner tube of the suction tip, an optical fiber arranged concentrically on the outer circumferential surface of the suction tube and optically connected to the tubular body, and an outer tube surrounding the optical fiber and the inner tube; A suction chamber including a connection joint connected to a rear end of the suction tube, a light source disposed on an outer circumferential surface of the connection joint and optically connected to the optical fiber, and a suction pump connected to the connection joint to supply a vacuum force; Provided is a medical suction device having an illumination function.

Disposable suction tip according to the present invention is made of a light transmission medium itself as the suction tip itself to the illumination light supplied through the optical fiber from the light source can perform the suction operation at the same time. Therefore, even if only the surgical and treatment space of the size that the suction tip can penetrate while providing sufficient lighting therein, there is an advantage that the suction operation can be performed smoothly. In addition, the suction tip itself is easy to disassemble and assemble, and if necessary, there is an effect that can be disposed of directly after contact with the affected part of another person to prevent transmission, or for other sanitary reasons. In particular, there is also an economical effect that only the suction tip can be treated during separation and disposal.

Medical suction device having an illumination function according to the present invention is configured separately from the light source, and by transmitting the light to the suction tip using the optical fiber, the electrical energy that can harm the patient and the operator is completely blocked, purely only the illumination light The safety tip can be increased by transferring to the suction tip.
