Abstract
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, so that it is easy to form a larger and more unobstructed specimen collection space after expansion. Utility Model Content
[0009] The utility model provides a specimen taking bag through a natural cavity with a wire ring on the top, aiming to solve the disadvantages of the prior art and facilitate the specimen to be put into the specimen bag and 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 with a wire ring on the top, characterized in that:
[0012] The bag body has a containing cavity after being unfolded; the left rod and the right rod are bonded to the inner surface of the bag body;
[0013] The bag mouth of the bag body is sleeved on the wire ring, and the wire ring is accommodated in the hollow left side rod;
[0014] The left side rod and the right side rod are far away from each other. When the bag body is opened, the diameter of the wire ring is greater than the distance between the left side rod and the right side rod, and the width of the bag opening is greater than the width of the accommodating cavity.
[0015] The left side rod and the right side rod are symmetrical with respect to the axis of the bag body.
[0016] The left side rod comprises a left lower rod and a left upper rod, the left upper rod is telescopically inserted into the hollow left lower rod, the right side rod comprises a right lower rod and a right upper rod, the right upper rod is telescopically inserted into the hollow right lower rod, and the left lower rod and the right lower rod are bonded to the inner surface of the bag body.
[0017] A telescopic rod is fixedly arranged at the bottom end of the left lower rod, the left end of the telescopic rod is fixed on the left rod, the right end of the telescopic rod is fixed on the bottom end of the right rod, and the telescopic rod is also located in the bag body.
[0018] The telescopic rod comprises a hollow fixed rod and a movable rod, the left end of the fixed rod is fixed on the left rod, the left end of the movable rod is fixed in the fixed rod, and the right end of the movable rod is fixed at the bottom end of the right rod.
[0019] The bag body comprises an inner wall and an outer wall, an air cavity is formed between the inner wall and the outer wall, and the outer wall has an inflation port. The air cavity shrinks in an uninflated state and expands in an inflated state.
[0020] The cross section of the air cavity after expansion is elliptical.
[0021] The utility model is beneficial in that:
[0022] 1. When not in use, it is in a contracted state. In this state, the volume is small and it is easier to put into the abdominal cavity through the hole of the laparoscope;
[0023] 2. The specimen bag is expanded by the stent. The expanded specimen bag is helpful to resist the blocking effect of the anal sphincter due to the structural strength provided by the stent, so that the specimen removal channel becomes larger and more conducive to specimen removal, overcoming the defect of ordinary specimen bags being soft and without expansion function.
[0024] 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.
[0025] 4. The wire ring of the utility model can be expanded outward at the uppermost end of the specimen bag, 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.
[0026] 5. The retractable side rods make the specimen bag small when not in use.
[0027] 6. The inflated air cavity increases the structural strength of the specimen bag, which is beneficial to resisting 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.
