Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention.

FIG. 1 is a perspective view of a suction washing tube according to an embodiment of the present invention. Referring to FIG. 1, the present invention includes a suction washing tube 100 inserted into a surgical site during laparoscopic surgery, ; The washing water pipe 200 is installed on the wall surface of the inner diameter passage 120 formed at the center of the suction washing pipe 100 and has an induction hole 233 for supplying the washing water to the surgical site, and; And an outlet hole (300) formed at the tip of the suction cleaning pipe (100) and connected to the induction hole (233) of the washing water pipe (200).

FIG. 2 is a vertical sectional view of the aspiration flushing pipe of the present invention with respect to the outflow hole position. 2, an outflow hole 300 is bored at an angle of 120 ° with respect to an inner diameter passage 120 provided at the center of the suction wash pipe 100, and the vicinity of the tip of the suction wash pipe 100 is punctured .

In order to form the outflow hole 300 at an angle of 120 °, the supplied wash water is dispersed to be supplied to the surgical site in a comprehensive manner, and also to prevent a phenomenon in which a surgeon hits the surgical site.

In the inner diameter passage 120 of the suction washing pipe 100 having the water outlet 300, a washing water pipe 200 for supplying the washing water to the surgical site is installed.

When the washing water pipe 200 is installed in the inner diameter passage 120, it is preferable that the washing water pipe 200 is installed at a position where the water outlet hole 300 is opened.

Therefore, the suction washing pipe 100 is provided with a washing water pipe 200 for supplying washing water to a surgical site, an inner diameter passage 120 formed therein, and an inner diameter passage 120 for sucking contaminated water washed do.

FIG. 3 is an explanatory view of a washing water pipe according to the present invention. The washing water pipe 200 installed on the inner diameter passage 120 of the suction washing pipe 100 includes a water pipe 210 formed of a single pipe, A longitudinal position of the water pipe 210 is branched so as to form a plurality of branch pipes 230, 230A, and 230B.

When the washing water pipe 200 is installed, the water pipe 210 of the washing water pipe 200 is installed on the rear side of the inner diameter channel 120 of the suction washing pipe 100, So that the branch pipes 230, 230A, and 230B are installed in the tip direction of the suction cleaning pipe 100. The ends of the branches 230, 230A and 230B of the washing water pipe 200 are spaced apart from the front end of the suction washing pipe 100 with a gap T therebetween.

With the provision of the washing water pipe 200, a new induction hole 233 through which only washing water is supplied is formed in the inner diameter passage 120 of the suction washing pipe 100. The induction hole 233 is connected to the outflow hole 300 formed at the tip of the suction cleaning pipe 100.

The washing water is supplied along the inner diameter passage 120 of the suction washing pipe 100 and the induction hole 233 of the washing water pipe 200 in a state where the washing water is divided at an angle of 120 degrees with respect to the surgical site At the same time, the washing water is supplied through the outflow hole 300 to a wider range than the washing water supplied from the induction hole 233.

4 is a view illustrating an example of a protrusion formed on an outer surface of a suction cleaning tube according to the present invention. The protrusion 150 protrudes around an outflow hole 300 formed in the suction cleaning tube 100, The protrusion 150 may protrude in the longitudinal direction or the longitudinal direction of the suction cleaning pipe 100 at the periphery of the water outlet or may protrude in the form of a lattice in which the protrusions in the lateral direction and the longitudinal direction are combined You may.

The guide tube 100 may further include a guiding tube having a smooth surface for easily inserting the suction cleaning tube 100 into an operation position during laparoscopic surgery.

FIG. 5 is a transverse cross-sectional view of a guide pipe connected to the outer diameter of the suction cleaning tube of the present invention, and FIG. 6 is a cross-sectional view of the suction pipe shown in FIG.

In forming the suction cleaning tube 100 of the present invention, it is preferable that the protrusion 150 formed at the outer diameter of the suction cleaning tube 100 has a structure in which the surface of the organ at the surgical site is located on the outer diameter of the suction cleaning tube 100 A space is formed between the surface of the organ and the outer diameter of the suction cleaning pipe 100 so that the air does not move smoothly.

As the protrusion height of the protrusion 150 increases, the space between the surface of the organ and the suction cleaning tube 100 increases. However, when the protrusion height is high, when the protrusion 150 is inserted into the laparoscope The protruding portion 150 is preferably made of silicone or rubber, which is a material to be pressed by compression, since it is resistant to insertion and is caught and can not be quickly inserted.

A guide pipe 400 having an inner diameter sufficient to insert the suction cleaning pipe 100 into the outer diameter of the suction cleaning pipe 100 having the compressed and pressed protrusion 150 is mounted.

Accordingly, when the suction cleaning pipe 100 is inserted into the inner diameter of the guide pipe 400, the protrusion 150 is compressed and pressed as shown in FIG.

When the protrusion 150 is compressed by the guide pipe 400, the guide pipe 400 is stably mounted on the outside of the suction pipe 100 by the repulsive force of the protrusion 150, A flow path 430 through which air and liquid can move is formed between the guide tube 150 and the guide tube 400.

 Since the protrusion 150 is compressed when the guide tube 400 is mounted on the outer diameter of the suction cleaning tube 100, the outer diameter of the guide tube 400 is smooth without any protruding surface, The flow path 430 formed between the suction cleaning pipe 100 and the guide pipe 400 is inserted into the laparoscope through the air or the liquid at the surface of the organ And thus the separation membrane phenomenon which prevents the surface of the organ from sticking to the outer diameter surface of the guide pipe 400 is formed.

When the tip of the suction cleaning tube 100 covered with the guide tube 400 is close to the operation site of the laparoscope, the guide tube 400 is moved to the back of the suction cleaning tube 100 as shown in FIG. 6 .

When the guide pipe 400 is moved, the protruding portion 150 is exposed. At the same time, the pressed state is restored and the surface of the organ around the suction cleaning pipe 100 is pushed out, So that the surface of the organ is not closely attached to the outer surface.

When the organs around the suction cleaning pipe 100 are lifted due to a phenomenon in which the protruded portion 150 is returned, the cleaning water sprayed from the natural water outlet 300 and the branch pipes 320, 320A and 320B ) Is simultaneously supplied to the surgical site, so that the wash water is supplied in a wide range.

In the aspiration flushing pipe 100, the contaminated water opposite to the supply of the flushing water is also sucked by suction force formed in the inner diameter channel 120 of the suction flushing pipe 100, The surface of the suction pipe may be inserted into the inner diameter passage 120 of the suction pipe 100. In the suction pipe 100 of the present invention, Suction force is generated in the induction hole 233 of each branch pipe 320, 320A, and 320B in a state where the branch pipes 320, 320A, and 320B are divided at the angle of 120 degrees to the tip of the inner diameter passage 120 And a gap T is formed between the tip of the branch pipes 320, 320A and 320B and the inlet of the suction cleaning pipe 100. Therefore, the suction force of the suction cleaning pipe 100 Even if the surface of the inner diameter passage 120 is pulled to the inlet of the inner diameter passage 120, The surface of the organ does not come into close contact with the inlet of the inner diameter passage 120 due to the gap 320 between the branch pipes 320 and 320A and 320B and the inner surface of the inner diameter passage 120, do.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is to be understood that the invention may be embodied in many other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
