Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a specimen retrieval bag for laparoscopic appendectomy. Background Technology

[0002] Laparoscopic appendectomy (LA) is now widely performed in clinical practice. Compared with traditional open appendectomy, it has significant advantages in terms of postoperative complication rate and postoperative recovery. However, if LA is not handled properly, many complications can still occur. For example, improper handling of the appendix specimen can lead to prolonged operation time, increased damage to the puncture site during the operation, and postoperative puncture site infection.

[0003] Currently, invention patent CN216090612U discloses an appendix removal bag, including a bag body and a pull rope. The bag body has an open opening with several pull rope holes around its edge. The pull rope passes through these holes sequentially. The bottom diameter of the bag body is smaller than its opening diameter, making the bag narrow at the bottom and wide at the opening. This device can be used to remove the appendix during surgery, offering convenience and speed. It addresses the problem that existing retrieval bags are often large, causing the appendix to easily curl up inside and making it difficult to remove through the trocar opening of a laparoscope. Furthermore, many retrieval bags are made of opaque latex material, preventing doctors from observing the inside of the bag during use.

[0004] Existing appendix specimen collection bags are bulky, while appendectomy is a minimally invasive procedure with a small incision opening. The specimen collection bag is not smooth enough when inserting and removing the appendix specimen from the incision opening, and there is a risk of tearing the incision opening. To solve the above problems, this application proposes a specimen retrieval bag for laparoscopic appendectomy.

[0005] The above statements are for the purpose of providing background information in relation to this application only and do not necessarily constitute prior art. Utility Model Content

[0006] (a) Purpose of the utility model

[0007] To address the technical problems existing in the background art, this utility model proposes a specimen retrieval bag for laparoscopic appendectomy. A vacuum device can extract the air from the specimen storage bag, reducing its volume and allowing it to be inserted into the minimally invasive opening. After the appendix specimen is placed inside, the bag can be quickly sealed. The vacuum device then extracts the air from the bag again, and the vacuum sealing valve compresses the appendix, further reducing the volume of the specimen storage bag. This facilitates the removal of the specimen storage bag from the minimally invasive appendectomy opening, thus solving the problems mentioned in the background art.

[0042] Existing appendix specimen storage bags are relatively large, while appendectomy is a minimally invasive procedure with a small incision opening. The specimen storage bag is not smooth enough when it is inserted into and inserted into the appendix specimen and then pulled out of the incision, which may cause the incision to tear.

[0043] In view of this, this application provides a specimen retrieval bag for laparoscopic appendectomy. The air inside the specimen storage bag can be extracted by a vacuum device, reducing the volume of the specimen storage bag. This allows the specimen storage bag to be inserted into the minimally invasive opening. After the appendix specimen is placed inside, the specimen storage bag can be quickly sealed. The vacuum device extracts the air inside the specimen storage bag again, and the vacuum sealing valve can compress the appendix, further reducing the volume of the specimen storage bag. This makes it easy to remove the specimen storage bag from the minimally invasive appendix opening.

[0044] According to some embodiments of this application, such as Figure 1-6 As shown, the present invention proposes a specimen retrieval bag for laparoscopic appendectomy, including a specimen storage bag 1. Both ends of the specimen storage bag 1 are provided with spindle-shaped heads 2, so that the specimen storage bag 1 has an overall spindle-shaped structure. The middle of the side wall of the specimen storage bag 1 is provided with an installation groove 4, which is located between the two sets of spindle-shaped heads 2.

[0045] The inner wall of the mounting groove 4 is provided with a delivery port 5 for inserting and removing the appendix. The inner wall of the delivery port 5 is provided with a self-sealing strip 6. A sealing handle 7 is slidably provided on the surface of the self-sealing strip 6. The sealing handle 7 moves on the self-sealing strip 6, and the inner wall of the sealing handle 7 squeezes the self-sealing strip 6 so that the self-sealing strips 6 interlock with each other.

[0046] The specimen storage bag 1 has a vacuum connection tube 12 that is movably inserted into the top surface for connecting to an evacuation device.

[0047] It should be noted that the vacuum connecting tube 12 is inserted into the connector 11, allowing the specimen storage bag 1 to be connected to the vacuum equipment. The vacuum equipment can extract the air from the specimen storage bag 1. After the vacuum sealing valve 13 is closed, the specimen storage bag 1 is sealed, reducing its volume. This allows the specimen storage bag 1 to be inserted into the minimally invasive opening. Opening the vacuum sealing valve 13 allows air to enter the specimen storage bag 1. The minimally invasive surgical forceps clamp the sealing handle 7 and push the sealing handle 7 to move on the self-sealing strip 6, opening the delivery port 5. The removed appendix specimen can then be delivered through the delivery port. The specimen bag 1 is placed into the inlet 5. After the sealing handle 7 is pushed in the opposite direction, the inner wall of the sealing handle 7 squeezes the self-sealing strip 6, which can quickly close the self-sealing strip 6 to seal the specimen bag 1. The surgical forceps are stuck in the limiting slot 8, which can limit the surgical forceps and facilitate the opening and closing of the self-sealing strip 6. The vacuum device extracts the air from the specimen bag 1 again and seals it through the vacuum sealing valve 13. The vacuum sealing valve 13 can compress the appendix and reduce the volume of the specimen bag 1, so that the specimen bag 1 can be easily removed from the appendix micro-invasive orifice.

[0048] In this embodiment, as Figure 1As shown, the outer wall surface of the specimen storage bag 1 is provided with arc-shaped chamfers 3 at all corners, and the surface of the specimen storage bag 1 is made more rounded at the corners by the arc-shaped chamfers 3.

[0049] It should be noted that the specimen storage bag 1 has rounded corners 3 on its surface, making the edges more rounded and allowing the specimen storage bag 1 to enter and exit the micro-invasive hole more smoothly.

[0050] In this embodiment, as Figure 3 As shown, the sealing handle 7 has limit slots 8 on both sides of its surface. The limit slots 8 are equidistantly distributed. When the sealing handle 7 moves to both ends of the self-sealing strip 6, it abuts against the inner wall of the mounting groove 4 to limit the sealing of the handle 7.

[0051] It should be noted that the sealing handle 7 is limited by the inner wall of the mounting groove 4 when it moves, which can prevent the sealing handle 7 from falling off and improve the safety during use.

[0052] In this embodiment, as Figure 3 As shown, the specimen storage bag 1 is conductively connected to the top of the insertion seat 11, and the vacuum connection tube 12 is inserted into the insertion seat 11. The surface of the shuttle-shaped head 2 at the top of the specimen storage bag 1 is provided with a flat section 10, which facilitates the fixing of the insertion seat 11. Both surfaces of the specimen storage bag 1 are printed with scale lines 14 for measuring appendix specimens. A vacuum sealing valve 13 for vacuum sealing is installed on the vacuum connection tube 12.

[0053] It should be noted that the flat section 10 facilitates the fixing of the connector 11, the scale line 14 facilitates the measurement of the length of the removed appendix, and the vacuum sealing valve 13 facilitates the sealing of the specimen storage bag 1.

[0054] In this embodiment, as Figure 1 As shown, sealing plates 9 are provided on both sides of the inner wall of the mounting groove 4. After the specimen storage bag 1 is evacuated, the two sets of sealing plates 9 abut against each other to seal the mounting groove 4.

[0055] It should be noted that after the specimen storage bag 1 is evacuated, the two sets of sealing plates 9 abut against each other to seal the mounting groove 4, making the surface of the specimen storage bag 1 smoother and the placement smoother.

[0056] The working principle and usage process of this utility model: The vacuum connecting tube 12 is inserted into the connector 11, allowing the specimen storage bag 1 to be connected to the vacuum equipment. The vacuum equipment can extract the air from the specimen storage bag 1. After the vacuum sealing valve 13 is closed, the specimen storage bag 1 is sealed, reducing its volume. This allows the specimen storage bag 1 to be inserted into the minimally invasive opening. Opening the vacuum sealing valve 13 allows air to enter the specimen storage bag 1. The minimally invasive surgical forceps clamp the sealing handle 7 and push the sealing handle 7 to move on the self-sealing strip 6, opening the delivery port 5. The removed appendix specimen can be placed into the specimen storage bag 1 through the delivery port 5. Pushing the sealing handle 7 in the reverse direction... After the sealing handle 7 is sealed, the inner wall of the sealing handle 7 compresses the self-sealing strip 6, which can quickly seal the self-sealing strip 6 to seal the specimen storage bag 1. The surgical forceps are locked in the limiting slot 8, which can limit the surgical forceps and facilitate the opening and closing of the self-sealing strip 6. When the sealing handle 7 moves, it is limited by the inner wall of the mounting slot 4, which can prevent the sealing handle 7 from falling off and improve the safety during use. The vacuum device extracts the air from the specimen storage bag 1 again and seals it through the vacuum sealing valve 13. The vacuum sealing valve 13 can compress the appendix and reduce the volume of the specimen storage bag 1, so that the specimen storage bag 1 can be easily removed from the appendix micro-invasive orifice.
