Description

OPTICAL SUCTION CATHETER
TECHNICAL FIELD
The present invention relates to an optical suction catheter, more particularly, to an optical suction catheter that can enable suction by irradiating a predetermined light on a small operation area so as to perform exact and proper suction for various surgical operations.
BACKGROUND ART
Suction equipment is used in an operating room so as to suck up blood, liquor, pus and other saburra by using a vacuum apparatus and to remove them.
As shown in FIG. 3, the suction equipment includes a suction apparatus 25, a suction catheter 20 and a suction tube 23. The suction apparatus 25 includes a suction jar 26 and a compressor 27. The suction jar 26 is designed to suck foreign substance and other saburra in, to perform lavage and disinfection, and to be resistant against microbiosis. The compressor 27 supplies the suction jar 26 with absorptive force. The suction catheter 20 can easily access to an operation area. The suction tube 23 connects the suction jar 26 with the suction catheter 20.
However, such a suction equipment cannot efficiently suck up blood, liquor, pus and other saburra coming out during various operation. In other words, since the operation area is generally very small, it is difficult to exactly find out the operation area by using a lightening unit on the operation table. DISCLOSURE OF THE INVENTION
The present invention has been made to solve the aforementioned problem, and provides an optical suction catheter enabling a proper suction by irradiating a light on an operation area to thereby exactly determine a suction portion.
According to an aspect of the present invention, there is provided an optical suction catheter including: an optical irradiator functioning as an optical transmission path of a predetermined length on which a sheath of a predetermined thickness is formed, and having a light projector at an end thereof and an optical connector at the other end thereof, the light projector projecting an incident light, the optical connector being connected to a light generator through an optical fiber of a predetermined length; and a suction nozzle shaped in a tube having a predetermined inner diameter so as to be sealingly coupled with the optical irradiator, and having a connector of which one end is further protruded than the optical irradiator and has a suction hole formed adjacent to the optical irradiator and penetrating through an inside of the connector, and the other end is connected to a suction unit through a suction tube, the suction unit sucking out various foreign substances by a predetermined absorptive force . The optical suction catheter further includes a transparent protection member formed at the light projector and formed of material having a predetermined strength. The optical transmission path is an optical fiber. The optical transmission path is an optical waveguide. BRIEF DESCRIPTION OF THE DRAWINGS
The above objects, other features and advantages of the present invention will become more apparent by describing the preferred embodiments thereof with reference to the accompanying drawings, in which:
FIG. 1 illustrates an optical suction catheter according to an embodiment of the present invention;
FIG. 2 is an application state diagram of an optical suction catheter according to an embodiment of the present invention; and
FIG. 3 is an application state diagram of a conventional optical suction catheter.
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.
FIG. 1 illustrates an optical suction catheter according to an embodiment of the present invention. FIG. 2 is an application state diagram of an optical suction catheter according to an embodiment of the present invention.
As shown in FIGs. 1 and 2, an optical suction catheter includes an optical irradiator 10 for irradiating a constant light and a nozzle 20 sealingly coupled with the optical irradiator 10.
The optical irradiator 10 is an optical transmission path of a predetermined length on which a sheath of a predetermined thickness is formed. The optical irradiator 10 has a light projector 11 at an end thereof and an optical connector 12 at the other end thereof. The light projector 11 projects an incident light. The optical connector 12 is connected to a light generator 15 through an optical fiber 13 of a predetermined length. It is desirable that the optical transmission path is an optical fiber, but it is not limited to the optical fiber. The optical transmission path may be an optical waveguide. The sheath of the optical transmission path can be made of a synthetic resin or a metal that is harmless to a human body, and can protect the optical transmission path therein from damage. The optical suction catheter can further include a transparent protection member formed at the light projector 11 and formed of material having a predetermined strength.
The transparent protection member can be formed of a "glass lens so that a projected light can be radiate in straight line direction or radial direction. When lavage is performed to remove a foreign substance adhered to the light projector 11 after suction is performed, The transparent protection member is desirably made of material to have so enough strength that the light projector 11 is not destroyed. The optical connector 12 is a general optical connector, and is connected to the light generator 15 through the optical fiber 13 so as to prevent a light from being leaked. It is desired that the light generator 15 is an ultraviolet lamp of 500 - 2000 W. Since it belongs to a well-known technology, the description on it will be omitted.
The suction nozzle 20 is shaped in a tube having a predetermined inner diameter so as to be sealingly coupled with the optical irradiator 10. The suction nozzle 20 has an inlet hole 21 at an end thereof and a connector 22 at the other end thereof. An end of the suction nozzle 20 is further protruded than the light projector 11 by a predetermined length so that suction is easily performed. The inlet hole 21 is connected to an inside at a portion adjacent to the light projector 11 so as to prevent the light projected from the light projector 11 from being scattered and also to prevent a foreign substance from being adhered to the light projector 11. The conventional suction apparatus 25 is connected to the connector 22 protruded outwards through a suction tube 23. The optical suction catheter constructed as described above makes it possible to perform an exact and proper suction by projecting a light to a small operation area by using the optical irradiator 10. Also, it can be utilized as an illuminator to illuminate the small operation area. The inlet hole 21 can efficiently prevent a foreign substance from being adhered to the light projector 11 when suction is performed. It is very advantageous for a user.
Although the preferred embodiments of the present invention have been disclosed for illustrative purpose, those skilled in the art will appreciate that various modifications, additions and substitutions can be made without departing from the scope and spirit of the invention as defined in the accompanying claims.
INDUSTRIAL APPLICABILITY
According to the present invention, when various surgical operation is performed, since the small operation area can be exactly and properly sucked, it is very convenient for an operator to use and helps the operator to perform operation in a short time. Also, it can be utilized as an illuminator to illuminate the small operation area.
