Description

Fecal diverting device

[0001] The present invention relates to a medical artificial intestinal tract administration device for providing a bypass passage, and more particularly, it relates to a medical artificial intestinal tract administration device for preventing a leakage of side flaps at an anastomosis site of a colon or intestine (large intestine, rectum, etc.) To the artificial intestine management device.

Colon cancer is a malignant tumor of the colon and rectum, most commonly adenocarcinoma arising in the mucosa of the colon. In addition to adenocarcinomas, squamous cell carcinoma, malignant lymphoma, malignant sarcoma and malignant chalcogenide tumors are rarely found. Sometimes the cancer of the surrounding organs invades the colon or the cancer developed in other areas is transferred to the large intestine. Most of the adenocarcinomas occur because benign tumors (polyps, polyps) are advanced.

These colon cancers can be divided into ascending and descending colon cancer and rectum cancer based on the location of the incompetence. Rather than ascending colon cancer, descending colon cancer is higher than that of descending colon cancer. This is because the effect of pancreatic enzymes is getting less and less.

In general, colon surgery is performed by cutting the upper and lower parts of the affected part and connecting and sealing the normal parts. However, complications such as surgical site infection caused by leakage from the anastomosis site are significantly higher in rehospitalized patients.

The incidence of leak after colon surgery has been reported to be very high, about 8%. In addition, unlike colon cancer patients who can undergo normal post-operative recovery after rectal surgery, rectal cancer with the highest incidence is removed to the adjacent anus, which makes it impossible to perform normal bowel movement even after recovery. And a bag for a bowel movement is connected to secure the artificial bowel passage.

Generally, in the case of an artificial anus, which is located at the lower abdomen, it is impossible to perform bowel movement due to peristalsis of the large intestine. This can cause problems such as limitations in activity and odor from leaking stools.

The management of such anus is very cumbersome and inconvenient, and most of the patients suffer from extreme mental suffering due to the stench caused by leaking stools, the prejudice of the surrounding people, the limitation of activity, and the inconvenience of wearing ordinary clothes. , The quality of life is deteriorating.

Numerous studies and attempts have been made in the world to improve the inconvenience of such anus, but no real alternative has been proposed.

Meanwhile, the long tubular tube 200 is connected to the body 100 to provide a bypass passage of the side, and is formed into a tubular shape having a predetermined length and inserted into the intestinal canal.

Such a tubular tube 200 is basically a biocompatible biodegradable material selected for use, and durability, antimicrobial, anti-seizure, and chemical resistance can be complemented, thereby improving the convenience of patients using an artificial anus.

Preferably, the long tubular tube 200 is made of a material selected from the group consisting of vinyl, silicone, and rubber, or a leak-proof coated fabric. That is, basically, materials with low coefficient of friction are used to prevent leakage of sides and smooth discharge of sides, and materials having good durability are used.

Particularly, when a water-repellent coated fabric is used for improving durability and antibacterial property, a biocompatible material is used, and examples thereof include PET (polyethylene terephthalate), PA66 (polyamide 66) and Teflon.

In general, PET is a synthetic polymer containing at least 85% of di-alcohols and terephthalic acid esters. Most of the textile companies in the world manufacture them, and from 0.1dtex microfibers to monofilaments, from clothing to industrial It is a fiber covering the use, cheap raw materials, versatile polymer properties, and wide range of materials for clothing and non-clothing fields.

In addition, since the molecular chain has a planar structure, it has high crystallinity, strong crystals, high strength, low elongation, good resistance to organic solvents, and excellent molecular symmetry. And has excellent shape stability. Therefore, it is used for artificial blood vessels, surgical sutures and artificial ligaments for medical use.

In the case of PA66 (polyamide 66), a structural unit of a fiber molecule is a synthetic polymer linked by an amide (CONH) bond. It is a polymer widely used in fields such as clothing and industrial fields for PET. It has high bulky hydrogen bonds and does not have bulky side chains. The molecular chains can be closely adjacent to each other. It is a polymer developed with crystals. After stretching process, the orientation and crystallization of fibers can be further developed and high crystallinity can be achieved. Both strength and elongation are very strong, and they are excellent in abrasion strength and heat resistance due to binder. Especially, they are used for blood purification polymers and artificial skin for medical purposes.

In addition, PTFE (polytetrafluoroethylene), which is widely known as Teflon, is used to prevent food sticking by coating on a cooking pans and it is used to make various artificial bodies because it does not solidify the blood even when entering human body.

Since it has a very stable chemical structure against heat, it is very easy to disinfect and has excellent hydrophobicity. Therefore, it is used not only as a material for artificial blood vessels, but also a porous PTFE membrane commonly called Gore-Tex. It is also used.

Using such a material, a fabric made in the form of a woven or knitted fabric is subjected to a waterproof coating.

The water-repellent coating may be formed by applying a resin-free liquid type silicon-coated resin or water-dispersed polyurethane resin to the fabric using the biocompatible material, or by laminating a thermoplastic polyurethane adhesive film on the fabric.

In the case of solvent-free type liquid silicone resin, it is composed of a total of two liquid types, namely a base resin and a curing agent. In a 10: 1 ratio of a base and a curing agent, Followed by stirring to prepare a silicone-coated resin.

In the case of the water-dispersed polyurethane resin, a hybrid water-dispersed polyurethane resin having a solid content of 50% or more was used, and various functional additives were compounded in a specific ratio in order to prepare a coating resin solution. For example, a rheology control agent (3.0 wt%), a crosslinking agent (3.0 wt%) and an anti-blocking agent (1.0 wt%) were added as a functional additive to a base resin, followed by stirring for 20 minutes to prepare an aqueous dispersion polyurethane resin Respectively.

Further, in the case of the adhesive film material for laminating, since it is necessary to have sufficient adhesion with the fabric, durability and barrier performance, a lamination material of a thermoplastic polyurethane multilayer adhesive film having a thickness corresponding to 100 m .

Such a resin coating can be realized by a doctor knife or dip coating process.

That is, a doctor knife method in which a liquid type coating resin is coated on the surface of the fabric using a doctor knife to thermally cure the resin, a resin coating method in which a cloth is impregnated with a coating resin, or a laminating method Thereby coating the resin.

As described above, the liquid silicone resin is considered to be a suitable material for the coating material of the fabric due to its environmental friendliness and excellent durability. In the case of the doctor knife method using a silicone resin, it is advantageous in terms of workability and production speed, It has the advantage of maintaining flexibility to some extent.

     The dip coating method is a method of dipping a fabric in a bath containing a coating resin for a certain period of time, followed by drying and curing by squeezing several times to pick up a uniform coating resin.

     Generally, in order to be applied as a coating material for impregnation, a uniform penetration into the inside of the fabric must be carried out. Therefore, the coating should have a viscosity of a certain level or less. A water borne type emulsion coating material is widely used as a typical coating material. Among them, polyurethane and silicone are most widely used as textile coating materials in terms of film formation and functionality.

    The dip coating method is very simple in principle and has advantages over a doctor knife or a roll coating in terms of production speed and efficiency.

When laminating an adhesive film, a thin film having adhesive properties is laminated on the surface of the fabric to cover the surface. In the case of special clothes having moisture permeability and durability, It is well known as a technology to replace coatings.

     Particularly, in order to have a non-toxic characteristic, it is necessary to limit the use of a harmful solvent to the human body. Therefore, instead of using a solvent type adhesive, an adhesive layer and a cover layer The film is prepared in advance, and then laminated by a strong pressing by a heating roller in the process of fusing with the fabric.

As described above, the present invention relates to a medical artificial intestinal tract administration device for providing a bypass passage, and particularly to prevent the occurrence of leakage of the side of the intestine of the colon or intestine (large intestine, rectum, etc.) And then discharged to the artificial intestine management apparatus.

Particularly, the present invention provides a fixed support on the outer side to be fixed to the intestine and a sealing part on the inner side to control the discharge of the side, thereby preventing direct contact of the side with the anastomotic site during drainage, There is an advantage that it can be easily removed from the intestinal tract by releasing the support.

In addition, when the sealing portion and the fixed support are formed in the form of a tube, an opening / closing valve for opening and closing the valve is integrally provided, which facilitates the use of the device and facilitates mounting and removal.

In addition, the intestinal canal tube according to the present invention is formed of a material for preventing water leakage, and is particularly biocompatible and has excellent durability and odor improving performance, and has a low coefficient of friction and excellent waterproofing property. To make it more convenient.

Further, according to the present invention, the use of the cover and the pusher prevents damage to the tube of the intestinal canal by the stamper at the anastomosis site, and smooth insertion of the intestinal tractor allows safe and quick operation.
