[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical collection bag for accommodating an organ or the like resected in a body cavity and extracting it from the body during endoscopic surgery.

[0002]

2. Description of the Related Art In recent years, surgical operations have been advocated for minimally invasiveness, and endoscopic surgery has been applied to many fields, and correspondingly, surgical instruments have been required to have functions adapted to various operations. Regarding medical collection bags, which are the technical field of the present invention, various configurations have been proposed and commercialized. Among them, for example, those used for malignant tumor lesions are required to have a function of securely closing the opening to avoid metastasis due to falling and scattering of the stored cells. Many bags are known that employ a means of providing a string at the periphery of the opening and pulling the string to contract the opening to close it.

[0003] As a conventional means for closing the opening of the extraction bag having the above configuration, for example, as in Japanese Patent Application Laid-Open No. Hei 8-19544, U.S.A. 2520062, US Pat. No. 5,037,379, US Pat. A passage for inserting the cord is provided, and one or both ends of the cord are provided at a length that can be pulled out of the body through the mantle tube from one cut-out portion of the passage, and the resected organ or the like is provided. An extraction bag has been proposed in which, after being stored, an end of the cord is pulled from outside the body to narrow and close the opening. Also, in Japanese Patent Application Laid-Open No. 7-328013, a band having a flat shape and partly or wholly provided with a concavo-convex shape as a cord-like body is attached by means for passing an insertion passage in the same manner as described above, and one end of the band is fixed. The other end of the band is inserted through the inner hole of the fastener provided with the inner hole, provided at the outlet from the band insertion passage of the bag, and one end of the band pulled out of the body is pulled to thereby remove the fastener. There is disclosed a device in which a spring-like projection provided inside is engaged with the unevenness of a band, whereby the mouth of the bag is squeezed and closed, so that the bag is not loosened again. Further, in Japanese Patent Application Laid-Open No. 6-205786, similarly to the above, a passage for inserting a drawstring is provided at the edge of the opening of the bag, and a cutout provided at two symmetrical positions of the opening in the passage is provided at both sides. An extraction bag has been proposed in which an end of a drawstring is pulled out and the opening is narrowed and closed by pulling the drawstring outside or inside a body cavity.

[0004]

[Problems to be solved by the invention] However, as described above, the application of endoscopic surgery has expanded and there are various demands for endoscopic collection bags. For example, lesions are present in multiple sites. In some cases, after one lesion is separated and stored, the bag is temporarily placed in the body cavity with the opening of the bag closed, and the bag is opened again to store another lesion, and after all the disease is stored. Finally, there is a demand to collect bags all at once, in which case it is necessary to open and close the bags many times in the body cavity, so that it is possible to securely close the bag and open it easily in the body cavity That is also important.

[0005] Considering conventional organ extraction bags for the above request, USP 5,037,379, U.S. Pat. Since there is no mechanism to securely hold the blockage, there is no problem if the time is short, but it is possible that the string-like body is loosened over time, the bag is opened, and the stored items fall or scatter. Sex cannot be denied. In particular, in the above-mentioned procedure, since it is expected that the indwelling body is left in the body cavity for a long time, the problem becomes apparent.

In Japanese Patent Application Laid-Open No. Hei 7-328013, the closure can be securely held by the fastener, but on the other hand, it is not considered to reopen the closed body once again in the body cavity, so that it is applied to the above-mentioned procedure. Can not. On the other hand, in the above-mentioned other conventional organ extraction bags, reopening in the body cavity except for the actual climbing 252006 is possible by pushing and expanding the edge of the opening of the bag with two forceps or the like. However, it is not easy to pinch the edge of the tightly closed opening with forceps and push it open while watching the monitor of the endoscope in the body cavity.

[0007] Furthermore, these conventional devices basically do not consider temporary placement in a body cavity, and, except for Japanese Patent Application Laid-Open No. 6-205786, use a cord-like body that is integrated with a mantle tube or that serves as a closing means. In order to avoid occupation of one incision by these collection bags, it is necessary in clinical practice to close the opening and then use a cord for closing when the patient needs to be placed temporarily from outside the body. Means such as cutting the bag midway and separating only the bag and leaving it in the body cavity have been selected.However, in procedures requiring repeated opening and closing, reopening is difficult as described above, and reocclusion after reopening In this case, the only possible means is to pull the end of the thread cut with forceps, but it is impossible or extremely difficult to do this in the abdominal cavity. In addition, including Japanese Patent Application Laid-Open No. Hei 6-205786, in which the placement of the entire bag in the body cavity is also applied, as described above, since the obstruction cannot be said to be reliable, there remains uneasiness in placing only the bag body for a long time during the operation. .

[0008] In view of the above problems, the present invention applies temporary placement of the entire instrument in a body cavity, and ensures that the opening is closed, and that the opening is easily opened and closed many times with forceps in the body cavity. It is an object of the present invention to provide an organ extirpation bag which can be inserted into a body cavity from a small-sized mantle tube with a simple structure.

[0009]

Means for Solving the Problems In the organ resection bag of the present invention, a thread serving as a guide for opening and closing the opening of the bag is inserted into a plurality of threading holes arranged at equal intervals around the opening of the bag. The back and front surfaces are alternately passed, the ends are connected, and a series of rings are formed.The ends drawn out from both sides from the symmetrical position of the opening of the bag are used as both ends. Each of them was formed, and a sliding piece slidable along the thread was provided between the forceps gripper and the bag body with the thread inserted therein.

It is desirable that the forceps gripping portions at both ends of the thread are formed by forming both ends of the thread in a loop shape.

[0011]

According to the organ extraction bag of the present invention, the opening of the bag body in the body cavity is closed and fixed with one forceps by grasping the forceps holding portion on the side provided with the sliding piece. By moving the sliding piece to the bag side with the forceps, the opening is narrowed between the other forceps holding part and the sliding piece and can be easily closed, and the sliding piece becomes a stopper and is closed. The state can be reliably maintained. On the other hand, the opening is grasped and fixed with one forceps on the forceps gripper on the side without the sliding piece, the sliding piece is moved to the forceps gripper side with the other forceps, and the aperture is released. It can be easily opened by pulling both sides of the forceps gripper or the edge of the bag with both forceps. With this operation, the opening can be easily opened and closed many times in the body cavity. In addition, since the opening of the bag can be easily opened and closed in the body cavity and the closed state can be reliably maintained in the body cavity, the entire extraction bag, which is particularly applicable to the present invention, should be kept in the body cavity. It is the best storage bag for

[0012] Furthermore, the bag has a simple structure in which a thread is passed through the bag body to form an annular shape, forceps holding portions are provided at both ends of the thread, and a sliding piece is attached. Since the device can be collected and stored in a very compact manner, the outer tube used for inserting the device into the body cavity can be reduced in diameter (eg, 5 mm). Can be manufactured. Further, by forming the forceps gripping portion in a loop shape at both ends of the thread, the gripping portion can be easily gripped with forceps without requiring other components, so that it is possible to further reduce the size and the manufacturing cost.

[0013]

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing the overall configuration of an embodiment of the present invention, and FIG. 2 shows a bag. In the organ extraction bag of this embodiment, a series of annular threads 2 serving as a guide for opening and closing the opening is provided on the edge of the opening 11 of the bag 1, and the thread 2 is symmetrical to the opening 11 of the bag 1. , The forceps holding portions 3a and 3b are inserted into both ends of the pulled out thread 2, and the thread 2 is inserted into the inner hole between the forceps holding portion 3a and the bag body 1. The sliding frame 4 was provided to make the basic configuration. Although the shape and the material of the bag 1 are not specified, the bag 1 needs to be wound and housed in a mantle tube when inserted into a body cavity as described later. (80mm x 150mm) with the shape of a V-shape or curvilinear cut at the bottom. The material is non-toxic, thin (Example: 0.05mm), flexible, shape recovery in the body cavity, and suitable for use. Polyethylene was used as a transparent resin bag that has the strength to withstand. Further, the bottom 13 of the bag 1 is sealed by heat welding, and a punch hole 12 is formed at an edge of the opening 11, more specifically, at a position 10 mm below the edge, as a hole for thread passage at equal intervals over one circumference. I made it. As the yarn 2, a yarn made of polyamide resin (nylon) was used in consideration of flexibility and strength, and a colored yarn was used in consideration of visibility by an endoscope in a body cavity. The bag 1 is attached to the bag 1 by punching holes 12 provided at the edge of the bag 1 alternately through the front and back surfaces, connecting the ends and providing the bag longer than the outer periphery of the opening of the bag 1. Installed as a series of loops. The forceps gripper 3 is located at a symmetrical position of the opening 11 of the bag 1, more specifically, at a position where the opening is the largest when the opening 11 is pulled to both sides almost at the middle from both ends of the opening 11. The tip of No. 2 was formed in a loop shape in consideration of the ease of grasping by forceps in the body cavity. The forceps gripper 3 may be attached to both ends of the thread as separate components. The sliding piece 4 is an elastic silicone resin capable of achieving both slidability (easy sliding) for moving the thread 2 as a guide and a stopper function for keeping the opening of the bag 1 closed. In this example, the thread 2 was inserted into an inner hole of a small-diameter hollow shape, and provided between the loop of one forceps grasping portion 3a and the bag.

FIG. 3 shows an accommodating means in an outer tube which serves as an insertion guide when inserting the organ extraction bag of the present invention into a body cavity through an incision hole. To support a hollow pipe 51 made of stainless steel or resin (Example: outer diameter 5 mm, length 200 mm) and pneumoperitoneum-type endoscopic surgery (technique of inflating the abdominal cavity by putting carbon dioxide etc. into the body cavity) From the end of the hollow pipe 51 of the outer tube 5 formed of a resin needle base 52 having a valve mechanism for preventing air leakage, a wound and rod-shaped organ extraction bag is press-fitted from the bottom 13 side of the bag 1, The forceps holding portion 3a on the side where the sliding piece 4 is provided is housed with a part or all of the forceps holding portion 3a extended. For removal in the body cavity, the forceps grasping portion 3a can be easily removed from the hollow pipe 51 by pulling with the forceps.

The opening / closing means of the opening 11, which is a feature of the present invention, is performed by pulling the forceps gripping part 3 in both directions and moving the sliding piece 4, as described in detail in the above-mentioned operation.
