Description

TECHNICAL FIELD [0001] The present invention relates to a nasal gas filter apparatus for a surgical trocar set,

The present invention relates to a harmful gas filter device for a surgical trocar set, and more particularly, to a harmful gas filter device for use in a laparoscopic surgery, which can be detachably attached to a connecting pipe through which harmful gas generated during surgery is removed The present invention relates to a new type of nasal gas filter device for use in a surgical trocar set that prevents external leakage of noxious gas, prevents damage caused by leakage of noxious gas, and provides a safe surgical environment.

In the conventional laparoscopic surgery, a surgical trocar set (also called a blade-less trocar) is being used. The laparoscopic surgical trocar set has a trocar for puncturing or puncturing the skin tissue in the laparoscopic surgical instrument. The laparoscopic surgical instrument is inserted into the patient's body, and after insertion, only the trocar is removed from the trocar set, Use the cannula cannula as it is. At this time, in order to secure the surgical space of the abdomen, carbon dioxide gas is usually put into the abdomen. During surgery, the body is incinerated and incised using an electric scalpel in the body, resulting in harmful gas or smoke. The harmful gas emitted at this time has been contaminated intact indoors with the supplied carbon dioxide gas.

FIG. 1 is a schematic perspective view of a surgical trocar set according to the prior art, and FIG. 2 is a longitudinal sectional view of FIG. 1.

1 and 2, a conventional surgical trocar set 10 includes a cannula 14 having a check valve therein, and a cannula 14 which is vertically movable in the center of the cannula 14. The upper part of the cannula 14 is connected to the upper part of the cannula 14 so as to prevent air from leaking into the cannula 14 at the same time as the upper part of the trocar 17b, In addition to the blocking function in the cannula 14, the hermetic means can also be used for the insertion of an endoscope or other surgical instruments during surgery, such as insertion or insertion after insertion through a cannula, (Reference numeral 17a denotes an upper end stopping jaw of the trocar 17b).

In most cases using the surgical trocar set 10 as described above, a certain amount of gas (usually carbon dioxide (CO 2) is injected to maintain the pressure of the abdomen of the patient during surgery, The gas is discharged to the coke 15. This gas contains harmful gas generated during oxidation of the foreign body, cancer tissue, or body tissue of the patient at the time of surgery and has a problem of leaking through the cock 15.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a new type of surgical instrument for preventing the leakage of noxious gas discharged from a body of a patient through a connection tube at the time of use of a surgical trocar set, And to provide a noxious gas filter device for a surgical use trocar set of the same.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a harmful gas filter device of a surgical trocar set according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a schematic side cross-sectional view of a noxious gas filter device of a surgical trocar set according to the present invention.

Referring to Figure 3,

A cap having a check valve inside thereof, a trocar cap vertically movably inserted in a central portion of the cap, and a cap having an upper portion and a lower portion on an upper portion of the cap to prevent air from leaking in the cap, A harmful gas filter device of a surgical trocar set including an airtight means,

The harmful gas filter device

A cylindrical body 21 having an inlet protrusion 22 protruding from a central portion on one side thereof and having a space for installing filter means in a 'C' shape on the inner side,

(24) protruding from a central portion on one side and positioned coaxially with the inlet protrusion (22) of the cylindrical body (21), the filter body (21) of the cylindrical body A cover portion 23 for closing the installation space,

The first filter portion 220, the second filter portion 230, and the second filter portion 230 are sequentially installed in the filter body installation space of the cylindrical body portion 21 and sequentially from the inlet protrusion 22 to the outflow protrusion 24, 3 filter unit 240 as shown in FIG.

In addition, the noxious gas filter device is connected to and communicates with the cock portion of the surgical use cap 10 through a connecting portion in a connection portion (A in FIG. 3). (However, It is of course possible that the connector can be constructed integrally with the inlet projection 22)

The connecting means is composed of a connecting pipe 25b and a threaded portion 25a extending to one end of the connecting pipe 25b. As shown in FIG.

The connection pipe 25b is partially inserted into the inlet protrusion 22 of the cylindrical body portion 21 to guide the exhaust gas to be filtered or discharged.

The connecting means is such that the screw 25a is screwed to the end of the connecting pipe 15a of the cork portion 15 of the trocar body and the connecting pipe 25b is connected to the connecting pipe 15a of the cork portion 15 So that they are communicated with each other. As a result, the gas in the surgical trocar 10 is guided to the harmful gas filter device through the connecting pipe 15a of the cock portion 15 and is filtered.

And spacers (222, 224) are provided on the first filter surface and the third filter surface, respectively, which are in contact with the space for installing the filter means of the cylindrical body portion, and are in the form of a ring-shaped band.

The first filter unit 220 and the second filter unit 240 are formed of a non-woven fabric,

The second filter unit 230 is made of activated carbon, and the activated carbon adsorbs the odor particles, and adsorbs organic gas or odorous substances because of its excellent adsorption performance.

There are many kinds of activated carbon, such as absorbing benzene well and absorbing carbon tetrachloride well depending on kinds. In the present invention, activated carbon of various kinds of materials may be mixed and used.

Nonwoven fabrics, fabrics, fibers, felt and the like made of fibrous activated carbon may be used instead of activated carbon.

As described above, according to the noxious gas filter device of the surgical trocar set according to the present invention, the gas discharged from the surgical trocar set passes through the noxious gas filter device through the coke-side connection pipe. At this time, part of the air is filtered while passing through the first filter unit 220, and noxious gas is adsorbed by passing through the second filter unit 230. Finally, .

Meanwhile, when the operation is prolonged, the noxious gas filter device should be replaced with a good one. At this time, the width of mounting the activated carbon of the second filter unit 230 can be increased. In addition, it can be used selectively for 1 hour, 2 hours, etc. depending on time, and it is possible to use multiple stages by assembling several filter devices.

In actual use, the surgical trocar set is inserted into the abdomen of the patient, so that the noxious gas filter device portion is rested on the patient's body (for example, the abdomen), so that it can be used with stability.

In the present invention, the carbon dioxide gas initially introduced is discharged to the outside, the solid particles of the smoke are filtered by the first and third filter portions, and only the odor particles are selectively adsorbed and filtered in the second filter portion.

The reference character S1 denotes a space formed due to the characteristics of the second filter unit 230 mounted in the harmful gas filter device. The activated charcoal has a characteristic that the activated carbon is subjected to gravity and is directed downward by its own weight, A certain amount of dead space S1 is formed in the upper part. Therefore, if the gas passes through the space S1, it can not function as a filter. This problem is compensated for by the spacers 222 and 224 so that the gas can not pass through the space. (For example, when the inner diameter of the space for installing the filter means is 50 mm, the passage for gas or air is set to about 40 mm. (In the drawing, noxious gas does not pass from the upper part to the lower part).

The gas or smoke passes through the connecting pipe as shown by the arrow in Fig. Meanwhile, the carbon dioxide injected during the operation is discharged to the outside through the connection pipe as much as it is injected.
