Patent Description:
Colon cancer is a malignant tumor generated in the colon and the rectum, and most of colon cancer is adenocarcinoma generated in mucous membranes of the large intestine. In addition to adenocarcinoma, squamous cell carcinoma, malignant lymphoma, malignant sarcoma, and malignant carcinoid tumor are found on rare occasions. Once in a while, cancers generated in internal organs around the large intestine invade the large intestine, or cancers generated in regions other than the internal organs spread to the large intestine. Most of adenocarcinoma is generated as the result of growth of a benign tumor (polyp), which is an adenoma.

Colon cancer may be classified into ascending colon cancer, descending colon cancer, and rectal cancer based on the position of a lesion. Descending colon cancer has a higher disease incidence rate than ascending colon cancer, and rectal cancer has a higher disease incidence rate than descending colon cancer. The reason for this is that the effect of a pancreatic enzyme gradually decreases downwards.

In general, surgical operation of colon cancer includes incising the upper and lower ends of a diseased region and connecting normal regions to each other by stitching. However, anastomotic leakage after surgical operation may cause a serious postoperative complication, and may threaten the life of a patient. In addition, anastomotic stricture occurs for the long run, whereby the quality of life of the patient is seriously deteriorated.

It is reported that the frequency of occurrence of anastomotic leakage after surgical operation of colon cancer is about <NUM>% to <NUM>%, which is very high. In addition, since, for rectal cancer, which has the highest disease incidence rate, even the region adjacent to the anus is removed although the anus is not removed, normal bowel movement is attended with a serious difficulty even through a convalescent stage after surgical operation, unlike colon cancer patients, who are capable of performing normal bowel movement through a convalescent stage after surgical operation.

For temporary stoma (abdominal stoma) generally formed in order to reduce damage due to such anastomotic leakage, bowel movement based on the peristaltic movement of a large intestine is impossible, whereby feces are discharged at all times. Consequently, a colostomy bag must be worn at all times. As a result, limitations in activity and bad smells due to leaking feces may become an issue.

Management of such stoma is very troublesome and inconvenient. Above all, many patients feel severe mental pains for various reasons, such as bad smells due to leaking feces, biased views of people around the patients, limitations in activity, and inconvenience in wearing normal clothes, whereby the quality of life of the patients is deteriorated.

In order to solve such a problem, an artificial intestinal tract system for bypass of feces has been proposed in recent years.

A conventional artificial intestinal tract system includes an intestinal tract tube and a pair of fixing tubes. The artificial intestinal tract system is inserted into an intestinal tract, and the portion of the artificial intestinal tract system between the fixing tubes is fixed to the intestinal tract outside the intestinal tract using an intestinal tract band.

The most important thing in using the artificial intestinal tract system is to stably fix the artificial intestinal tract system to the intestinal tract, to prevent necrosis of the intestinal tract due to fixation, and to easily remove the artificial intestinal tract system after a predetermined period of time.

To this end, research on a biodegradable band has been actively conducted.

The biodegradable band is coupled to the portion of the artificial intestinal tract system between the fixing tubes. Since the biodegradable band must stably fix the artificial intestinal tract system, deformation or loosening of the biodegradable band must be minimized even though peristaltic movement is performed, and necrosis of the intestinal tract due to fixation must be prevented, it is very important supply the biodegradable band so as to exhibit appropriate tension while having a predetermined length.

Installation of a conventional biodegradable band is achieved by manually surrounding a biodegradable band estimated to have an appropriate length on the circumference of the intestinal tract between the fixing tubes and performing stitching or using a band installer capable of performing stitching and cutting at a predetermined length.

In the case in which the above method is used, however, it is not easy to supply a band having a length suitable for a patient, i.e. appropriate tension, and it is not easy to rapidly supply a band suitable for a patient at the time of surgical operation. Document <CIT> relates to a device that encircles a portion of the stomach to form a stoma opening of reduced diameter.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide an automatic tension measuring instrument capable of performing marking at a specific position of a band in response to tension applied to the band, whereby it is possible to easily estimate an ideal length of an intestinal band. The invention is defined in appended independent claim <NUM>. Further embodiments are defined in appended dependent claims.

In addition, the fixing protrusion may be formed so as to fix the position of the band in the state in which the band is drawn outside in a direction toward one side of the main body and to have a smaller inclination in an advancing direction of the band such that the band is not moved in the opposite direction.

Meanwhile, a cutting recess formed in the direction toward the one side of the main body so as to be adjacent to the marking part and configured to communicate with the first guideway and the second guideway in order to expose the band outside to enable cutting of the band.

Here, the band may be any one of an intestinal band, an auxiliary band, and an intestinal band/auxiliary band.

In addition, the automatic tension measuring instrument may be configured to measure tension applied to the band such that the stopper is operated when the tension reaches a predetermined level and marking is enabled on the band at that position.

Meanwhile, in the automatic tension measuring instrument, the distance from the portion marked on the band by the marking part to the portion of the band abutting fixing tubes of an artificial intestinal tract system may be <NUM> to <NUM> in response to the tension applied to the band.

First, the band <NUM> according to the present invention is formed long in a longitudinal direction, and is formed as any one of a biodegradable intestinal band configured to fix a well-known artificial intestinal tract system <NUM>, an auxiliary band, and an intestinal band/auxiliary band formed by overlapping the biodegradable intestinal band and the auxiliary band each other. In the case in which the intestinal band and the auxiliary band are used together, the auxiliary band is located at the inside, i.e. the portion abutting the intestinal tract.

In general, the intestinal band is woven using yarn, is configured not to be untied when fixing the artificial intestinal tract system <NUM>, is configured to exhibit tensile strength to some extent and not to be deformed even by peristaltic movement of the large intestine, and is made of a material that is biodegradable after a predetermined period of time while not damaging the outer wall of the large intestine. The intestinal band is generally woven using a mesh-shaped biodegradable stitching fiber and is then provided.

The auxiliary band <NUM> is made of a polymer material, such as polyurethane, and is made of a slippery and transparent material.

Each of the intestinal band and the auxiliary band is made of a material configured to extend when tension is applied thereto and to be automatically cut when the tension reaches a predetermined level or more or a material configured to be automatically cut when the tension reaches a predetermined level or more.

Hereinafter, the case in which the auxiliary band is used as an embodiment of the present invention will be described as an important point.

As shown in <FIG>, the case in which a cutting prearrangement part <NUM> configured to be cut when pulled at predetermined tension is formed at the other end of the auxiliary band <NUM> is shown. The cutting prearrangement part is provided so as to be cut when pulled at a force of about <NUM> to <NUM>, and is designed such that the length of the auxiliary band <NUM> when surrounding the portion of the artificial intestinal tract system <NUM> between the fixing tubes <NUM> and cut at predetermined tension is estimated to be an ideal length of the intestinal band.

In addition, the auxiliary band <NUM> may be designed such that tension applied to the auxiliary band is measured, the stopper is operated when the tension reaches a predetermined level, and marking is enabled on the auxiliary band <NUM> at that position, whereby the ideal length of the intestinal band is estimated based thereon. That is, a pressure sensor is installed in order to measure tension, i.e. pressure, applied to the auxiliary band <NUM>, a predetermined pressure level is set, and the stopper is automatically operated when the pressure reaches the predetermined pressure level, whereby it is possible to automatically measure tension.

Meanwhile, the intestinal band may be directly used in place of the auxiliary band, or a combination of the intestinal band/the auxiliary band may also be used. In the case in which the combination of the intestinal band/the auxiliary band is used, the intestinal band and the auxiliary band may be partially fixed to each other using a fixing hanger such that the intestinal band and the auxiliary band are prevented from moving separately.

In addition, the auxiliary band <NUM> is provided with a plurality of catching holes <NUM> formed in the longitudinal direction so as to catch the stopper <NUM> such that the position of the auxiliary band <NUM> is fixed by the stopper <NUM>, and a scale for size estimation may be marked on the entirety of the auxiliary band <NUM> or an indication part <NUM> may be formed at a specific position at which an effective region that can be estimated as an ideal length is marked in advance, as shown in <FIG>.

The main body <NUM> is formed such that the auxiliary band <NUM> is guided thereinto, one end of the auxiliary band <NUM> is fixed, and the other end of the auxiliary band is drawn outside, and has a structure in which the auxiliary band <NUM> is coupled to the interior thereof and the marking part <NUM>, and the stopper <NUM>, a description of which will follow, are provided at one side thereof.

As an embodiment of the present invention, the main body <NUM> is provided with a first guideway <NUM>, to which one end of the auxiliary band <NUM> is coupled and along which the one end of the auxiliary band is guided, and a second guideway <NUM>, to which the other end of the auxiliary band <NUM> is coupled and along which the other end of the auxiliary band is guided so as to be drawn outside the main body <NUM>.

A band fixing part <NUM> configured to fix one end of the auxiliary band <NUM> to one side of the main body <NUM> is formed at one side of the first guideway <NUM>, and, when the one end of the auxiliary band <NUM> is coupled, guided, and is drawn to one side of the main body <NUM> via the first guideway <NUM>, the one end of the auxiliary band <NUM> is fixed by the band fixing part <NUM> formed at the one side of the main body <NUM>.

The band fixing part <NUM> is configured to fix one end of the auxiliary band <NUM> to one side of the main body <NUM>, and holds the one end of the auxiliary band <NUM> in the form of clamps or is formed as male and female band fixing parts <NUM>, as shown, such that, when a catching recess <NUM> is formed in the auxiliary band <NUM> and a male band fixing part <NUM> is caught in the catching recess, a female band fixing part <NUM> is coupled to the male band fixing part, whereby the one end of the auxiliary band <NUM> is securely fixed to the one side of the main body <NUM>.

The second guideway <NUM> is formed so as to be open at the front and rear thereof such that the auxiliary band <NUM> is inserted and coupled, passes through the interior of the main body <NUM>, and is drawn outside the main body <NUM>, and, when the other end of the auxiliary band <NUM> that has passed through the second guideway <NUM> is drawn outside the main body <NUM> in the state in which one end of the auxiliary band <NUM> is fixed by the band fixing part <NUM>, predetermined tension is applied thereto, whereby the other end of the auxiliary band <NUM> is pulled.

As a result, the cutting prearrangement part <NUM> formed at the other end of the auxiliary band <NUM> is cut, and the pulled position of the auxiliary band <NUM> is marked, whereby it is possible to estimate an ideal length of the intestinal band.

In addition, a window part <NUM> formed so as to communicate with the second guideway <NUM> and configured to expose a specific portion of the auxiliary band <NUM> outside is provided in the main body <NUM>.

The window part <NUM> is configured to enable a user to observe the form in which the auxiliary band <NUM> moves as the other end of the auxiliary band <NUM> is pulled, whereby it is possible to recognize the indication part <NUM> of the auxiliary band <NUM> outside.

The marking part <NUM> is provided in the main body <NUM>, and is formed such that marking is enabled on the auxiliary band <NUM> at a specific position.

Specifically, the marking part <NUM> is provided in a predetermined region of the window part <NUM> in order to mark a specific position of the exposed auxiliary band <NUM>.

That is, when the cutting prearrangement part <NUM> is cut as the auxiliary band <NUM> is pulled at predetermined tension, marking is performed on the portion of the auxiliary band <NUM> exposed through the window part <NUM>.

The marking on the auxiliary band <NUM> may be performed through a writing utensil, or, as an embodiment of the present invention, the marking part <NUM> may be provided using a method of elastically pushing a specific position of the exposed auxiliary band <NUM>.

The marking part <NUM> is provided in a predetermined region of the window part <NUM>, and, as an embodiment, is made of a metal plate as a whole, and is fixed to opposite sides of the window part <NUM> so as to cover the window part <NUM>. A concave-convex pin <NUM> for marking on the auxiliary band <NUM> is provided at a specific position of the marking part <NUM>, and pushes the marking part <NUM> at a specific position of the auxiliary band <NUM> passing through the second guideway <NUM>, whereby marking is performed on the auxiliary band <NUM> by the concave-convex pin <NUM>.

The marking part <NUM> is formed such that elastic force is applied upwards and downwards by a thin metal plate and so as to return to the original position thereof after marking is performed at a specific position of the auxiliary band <NUM>.

The stopper <NUM> is formed at the main body <NUM> in order to stop the auxiliary band <NUM> at a predetermined position. Specifically, the stopper <NUM> is coupled to a receiving part <NUM> formed so as to communicate with the second guideway <NUM> and configured to provide a gap in which the stopper <NUM> is operated, and, when marking is completed by the marking part <NUM>, serves to fix the auxiliary band <NUM> at that position.

The stopper <NUM> includes a pushing part <NUM> coupled to the receiving part <NUM>, an elastic plate <NUM> coupled to the pushing part <NUM> in the state in which one side thereof is fixed to the main body <NUM>, the other side of the elastic plate being elastically operated in a vertical direction by the operation of the pushing part <NUM>, and a fixing protrusion <NUM> formed at the other side of the elastic plate <NUM> in order to fix the position of the auxiliary band <NUM> or to release the fixed position of the auxiliary band by the elastic vertical operation of the elastic plate <NUM>.

The pushing part <NUM> is exposed so as to be exposed outside the receiving part <NUM>, and, when the user operates the pushing part <NUM>, the elastic plate <NUM> is moved upwards and downwards. Since the elastic plate <NUM> is moved in the state in which one side thereof is fixed to the main body <NUM>, only the other side of the elastic plate <NUM> is elastically operated in the vertical direction by the operation of the pushing part <NUM>. The fixing protrusion <NUM> is formed at the other side of the elastic plate <NUM> in order to fix the position of the auxiliary band <NUM> or to release the fixed position of the auxiliary band by the elastic vertical operation of the elastic plate <NUM>.

That is, in the case in which the auxiliary band <NUM> is to be moved freely, the pushing part <NUM> is pushed to one side of the main body <NUM> (<FIG>) to move the other side of the elastic plate <NUM> upwards, and, in the case in which the auxiliary band <NUM> is to be fixed or the auxiliary band <NUM> is to be moved in the state in which the stopper <NUM> (the fixing protrusion <NUM>) is caught in one of the catching holes <NUM> of the auxiliary band <NUM>, the pushing part <NUM> is pushed to the other side of the main body <NUM> (<FIG>) to move the other side of the elastic plate <NUM> downwards.

The fixing protrusion <NUM> formed at the other side of the elastic plate <NUM> is formed so as to fix the position of the auxiliary band <NUM> in the state in which the auxiliary band <NUM> is drawn outside in a direction toward one side of the main body <NUM> and to have a smaller inclination in the advancing direction of the auxiliary band <NUM> such that the auxiliary band <NUM> is not moved in the opposite direction.

<FIG> are bottom perspective views showing an elastic plate <NUM> according to an embodiment of the present invention. A fixing protrusion <NUM> according to an embodiment of the present invention is formed at the other side of the elastic plate <NUM>, is formed so as to protrude downwards in a plate shape (<FIG>) or in a protrusion shape (<FIG>), is formed so as to be caught in one of the catching holes <NUM> of the auxiliary band <NUM>, is formed so as to have a smaller inclination in the advancing direction of the auxiliary band <NUM> such that the auxiliary band <NUM> can be moved to one side (in a direction toward one side of the main body <NUM>) and cannot be moved in the opposite direction (one-way stopper).

Meanwhile, a cutting recess <NUM> is further formed in a direction toward one side of the main body <NUM> so as to be adjacent to the marking part <NUM>, and communicates with the first guideway <NUM> and the second guideway <NUM> to expose the auxiliary band <NUM> outside such that the auxiliary band <NUM> can be cut.

When the cutting prearrangement part <NUM> of the auxiliary band <NUM> is cut and marking is completed at a specific position of the auxiliary band <NUM> (<FIG>), as described above, the auxiliary band <NUM> is cut through the cutting recess <NUM>, and the entire auxiliary band <NUM> is drawn from the main body <NUM>, whereby it is possible to estimate the length from the marked portion (a first reference) to the position at which the auxiliary band is inserted in to the first guideway <NUM> (a second reference) as an ideal length of the intestinal band.

The length from the marked portion, i.e. the first reference, to the second reference may be adjusted depending on the length or shape of the main body <NUM>, and the length of the intestinal band provided by the automatic tension measuring instrument according to the present invention so as to guarantee effective tensile force to the intestinal band and to stitch and fix the intestinal band while not disturbing peristalsis is estimated so as to have a small allowance.

Here, in the automatic tension measuring instrument, the distance d from the portion marked on the auxiliary band <NUM> by the marking part <NUM> to the portion of the auxiliary band <NUM> abutting the fixing tubes <NUM> of the artificial intestinal tract system <NUM> is preferably <NUM> to <NUM> in response to the tension applied to the auxiliary band <NUM>.

This configuration is set to provide a small allowance to the length of the intestinal band, and is connected with tension at which the auxiliary band <NUM> is cut when pulled (for example, <NUM> to <NUM>). For example, in the case in which the length of the intestinal band is about <NUM> when the intestinal band is pulled at a tension of <NUM>, the length of the intestinal band is about <NUM> when the intestinal band is pulled at a tension of <NUM>.

In addition, when the cutting prearrangement part <NUM> of the auxiliary band <NUM> is cut and marking is completed at a specific position of the auxiliary band <NUM> (<FIG>), the auxiliary band <NUM> may not be drawn through the cutting recess <NUM>, but the stopper <NUM> may be moved in a direction toward one side of the main body <NUM> in order to raise the elastic plate <NUM>, to release coupling between the fixing protrusion <NUM> and one of the catching holes <NUM> of the auxiliary band <NUM>, and to draw the auxiliary band <NUM> through the second guideway <NUM> in a direction toward the other side of the main body <NUM> (<FIG>). In this state, a marking M is formed on the auxiliary band <NUM>.

As described above, it is possible to estimate the length from the marked portion(M), i.e. the first reference, to the set second reference as an ideal length of the intestinal band.

Hereinafter, an illustration of operation according to an embodiment of the present invention shown in <FIG> will be described.

As shown in <FIG>, one end of the auxiliary band <NUM> is guided through the first guideway <NUM> of the main body <NUM> and is fixed by the band fixing part <NUM> at one side of the main body <NUM>, and the other end of the auxiliary band <NUM> is placed so as to surround the portion of the artificial intestinal tract system <NUM> between the fixing tubes <NUM>, is guided through the second guideway <NUM> of the main body <NUM>, and is drawn to the one side of the main body <NUM>.

At this time, the stopper <NUM> is pushed in a direction toward one side of the main body <NUM> to raise the elastic plate <NUM>, whereby coupling between the fixing protrusion <NUM> and one of the catching holes <NUM> is released, and therefore the auxiliary band <NUM> is moved freely.

As shown in <FIG>, as the auxiliary band <NUM> is moved to some extent, the stopper <NUM> is pushed in a direction toward the other side of the main body <NUM> to raise the elastic plate <NUM>, whereby coupling between the fixing protrusion <NUM> and one of the catching holes <NUM> is performed, and therefore the position of the auxiliary band <NUM> is fixed carefully as tension is increasingly applied to the auxiliary band.

As shown in <FIG>, when the cutting prearrangement part of the auxiliary band <NUM> is cut at tension appropriate to fix the fixing tubes <NUM> of the artificial intestinal tract system <NUM> to the intestinal tract, the marking part <NUM> is operated to perform marking at a specific position of the auxiliary band <NUM>. In this state, the auxiliary band <NUM> is fixed so as to be prevented from being moved in the opposite direction (a direction toward the other side of the main body <NUM>) by the stopper <NUM>.

As shown in <FIG>, the stopper <NUM> is moved to a direction toward one side of the main body <NUM> in order to raise the elastic plate <NUM>, to release coupling between the fixing protrusion <NUM> and one of the catching holes <NUM>, to draw the auxiliary band <NUM> in a direction toward the other side of the main body <NUM> through the second guideway <NUM>, and to measure the length from the marked portion M (the first reference) to the second reference, whereby an ideal length of the intestinal band is estimated.

As is apparent from the above description, the present invention provides an automatic tension measuring instrument capable of estimating an ideal length of an intestinal band configured to fix an artificial intestinal tract system, wherein marking is performed at a specific position of a band in response to tension applied to an intestinal band, an auxiliary band, and an intestinal band/auxiliary band, whereby it is possible to easily estimate an ideal length of the intestinal band.
