Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a specimen collection bag through a natural cavity. Background Art

[0002] At present, conventional surgery in clinical practice requires that the tumor specimen be removed from the body through an abdominal incision after the tumor specimen is removed. However, abdominal incisions are prone to complications such as incision infection and incision rupture. Secondly, abdominal incisions will leave scars on the abdomen. Therefore, the latest minimally invasive surgery method is not to remove the specimen through an abdominal incision, but to remove the specimen through natural cavities such as the anus. This surgery is more minimally invasive and avoids complications of abdominal incisions. However, when taking specimens through natural cavities such as the anus, a specimen bag is required to ensure the principle of sterility and tumor-free. The basic function of this specimen bag is to remove the lesion specimen during the operation, place the removed specimen in the specimen bag, and then remove it from the body through natural cavities such as the anus. The purpose of removing the specimen through the specimen bag is to help achieve the original sterile and tumor-free operation of the operation.

[0003] The specimen bag commonly used in clinical practice for taking specimens through natural cavities is a homemade loose plastic bag that is made by tying a knot at the end of the plastic bag. This common plastic bag will encounter many problems that make it inconvenient to take out the specimen.

[0004] Since it is made of ordinary plastic bags by tying the end sutures, it has the following disadvantages:

[0005] 1: The plastic bag is loose and has no expansion function. In addition, due to the contraction of the anal sphincter, there is not enough space to remove the specimen.

[0006] 2: The plastic bag is relatively soft, and the top of the bag is not easy to unfold, making it inconvenient to place the tumor specimen into the specimen bag from the top.

[0007] 3: When using this specimen bag to take specimens in clinical practice, the specimen bag is often in a state of being twisted together. In this state, it is more difficult to find a smooth passage to take out the specimen, thus increasing the difficulty of taking out the specimen.

[0008] The technology to solve this problem should be to make the specimen bag expandable, which will easily form a larger and more unobstructed specimen collection space. Secondly, the top of the specimen bag should be in an outward state, so that the space becomes larger after outward expansion and it is easier to put the tumor specimen into the specimen bag through the top. Utility Model Content

[0009] The utility model provides a specimen taking bag through a natural cavity which is expanded after being inflated, and aims to solve the disadvantages of the prior art, so as to facilitate the specimen to be put into the specimen bag and to facilitate the specimen bag to be taken out of the body from the natural cavity.

[0010] The technical solution adopted by the utility model to solve its technical problems is:

[0011] A specimen collection bag through a natural cavity that is expanded after being inflated, characterized in that:

[0012] The main body of the specimen bag is a sheet-shaped bottom wall connected to an annular hollow cavity surrounded by a cylindrical outer wall, a cylindrical inner wall, an annular top wall and a bottom wall;

[0013] The inflation tube passes through the bottom wall and connects the inside and the outside of the annular air cavity;

[0014] The cylindrical inner wall forms a lower accommodating cavity whose lower end is closed by the bottom wall and whose upper end is open;

[0015] The invention has a top conical bag body including a conical outer wall and a conical inner wall, the upper side of the conical outer wall and the upper side of the conical inner wall are connected to each other, the lower side of the conical outer wall is connected to the upper side of the cylindrical outer wall, the lower side of the conical inner wall is connected to the upper side of the cylindrical inner wall, and the conical outer wall and the conical inner wall enclose a conical annular hollow cavity with a closed upper end, an open lower end and connected to the annular hollow cavity;

[0016] The conical inner wall forms an upper accommodating chamber, the upper end of the upper accommodating chamber is open, and the lower end of the upper accommodating chamber is open and communicated with the lower accommodating chamber;

[0017] The bag has more than two air passages, the upper ends of which are fixedly connected to the outside of the conical outer wall and are closed by the conical outer wall, and the lower ends of which are fixedly connected to the through holes opened on the outer wall of the specimen bag body and communicated with the annular hollow cavity.

[0018] The invention is provided with four air passages which are evenly distributed around the circumference of the axis of the outer wall of the specimen bag body.

[0019] The utility model is beneficial in that:

[0020] 1. In the normal state, it is in a contracted and vacuum state, and its volume is small, so it is easier to be put into the abdominal cavity through the laparoscope's puncture hole;

[0021] 2. The outermost layer is expanded by inflation. The structural strength provided by the air pressure of the expanded specimen bag is helpful to resist the blocking effect of the anal sphincter, making the specimen removal channel larger and more conducive to specimen removal, overcoming the defect of ordinary specimen bags being soft and without expansion function.

[0022] 3. After the specimen bag is expanded, the specimen taking passage will naturally become smooth, so the resistance when taking the specimen will be reduced, overcoming the defect of the ordinary specimen taking bag that the rotation and twisting are not smooth and are not conducive to the opening state of the specimen taking passage.

[0023] 4. After the specimen bag of the utility model is inflated, the uppermost end of the specimen bag can be expanded outward, so that the opening at the upper end for loading the specimen becomes larger and it is easier to accommodate the specimen into the specimen bag, thus overcoming the defect that the upper end of the ordinary specimen bag cannot be opened and it is not easy to load the specimen into the specimen bag.
