[0043] A taking bag for laparoscope, further comprising a bag body assembly 3, installed at the push rod assembly 2 front end, to accommodate the pathological tissue, and safely and isolatedly take out the pathological tissue.

[0044] ​The bag assembly 3 comprises a main connecting rod 31, a side connecting rod 32, a bag opening strip 33, a rotating column 34 and a bag body 35. The bag opening strip 33 is arc-shaped and four bag opening strips 33 are arranged in a circle. The adjacent bag opening strips 33 are connected by the rotating column 34. On one hand, the bag opening strip 33 is convenient to be inserted into the main rod 1. On the other hand, the bag opening strip 33 is convenient to restore to the original state when it is unfolded. The bag body 35 is arranged below the bag opening strip 33. The main connecting rod 31 is arranged between the rotating column 34 at the rear side and the middle part of the moving block 22. The side connecting rod 32 is arranged between the rotating column 34 at the left and right sides and the moving block 22. The main connecting rod 31 and the side connecting rod 32 are rotatably connected with the rotating column 34 and the moving block 22. In the normal state, the bag assembly 3 is pressed and inserted into the main rod 1. At this time, the bag opening strip 33 is in the approximate straight line state. When in use, the pushing assembly pushes the moving block 22 to move forward along the main rod 1. Then, the main connecting rod 31 and the side connecting rod 32 drive the rotating column 34 and the bag opening strip 33 to move forward until the structure is completely stretched out of the main rod 1. At this time, the bag opening strip 33 restores to the arc-shaped structure and expands the bag body 35. The arrangement of the main connecting rod 31 and the side connecting rod 32 has the following advantages. 1. The tension is uniform when the bag opening strip 33 moves and expands, avoiding the deformation of the bag opening strip 33 and the bag opening of the bag body 35 caused by the unilateral stress concentration. 2. The operation is convenient. The power of the main connecting rod 31 and the side connecting rod 32 is transmitted through the moving block 22. The operator only needs to straightly push and pull the push handle 23 with one hand without rotating or adjusting the angle. 3. The minimally invasive adaptation.

In use, the motor 43 is started to drive the crushing shaft 42 to rotate, and the crushing knives 44 crush the tissues in the bag body 35.

[0048] The top surface of the mounting base 41 is provided with a collection groove 411. The collection groove 411 is distributed around the top surface of the mounting base 41, so that the crushed tissue liquid flows into the collection groove 411. The bottom of the collection groove 411 is connected with a discharge pipe 45. The bottom of the discharge pipe 45 extends to below the mounting base and is connected with a negative pressure pipe 46. The outer end of the negative pressure pipe 46 is provided with a quick connector 47. The bottom of the main rod 1 is provided with a plurality of pipe buckles 48. The negative pressure pipe 46 is fixed to the inner side of the pipe buckle 48. The quick connector 47 is connected with a negative pressure source. On the one hand, the liquid in the bag body 35 is extracted. On the other hand, the bag body 35 is shrunk to extrude the crushed tissues together, further reducing the volume of the bag body 35, and facilitating the removal from the laparoscope incision.

[0049] The top surface of the mounting base 41 is rotatably connected with a plurality of extension plates 49. The bottom surface of the extension plate 49 is fixedly connected with the bag body 35. The extension plates 49 are arranged at equal intervals along the mounting base 41. On the one hand, the extension plates 49 can protect the bag body 35 from being cut by the crushing knives 44, causing the tissues in the bag body 35 to leak. On the other hand, the extension plates 49 can assist in unfolding the bag body 35, unfolding and flattening the bottom of the bag body 35, and facilitating the loading of more tissues.

[0050] The closure assembly 5 is installed at the top of the bag body assembly 3. The closure assembly 5 needs to be closed when crushing tissues and removing the bag. This avoids the splashing of tissues and causes iatrogenic implantation risks.

[0051] The closing assembly 5 comprises a shielding cloth 51, a pull rope 52, a pull rope ring 53, a pulling block 54 and a closing handle 55, the shielding cloth 51 is arranged at the top edge of the bag body 35, the shielding cloth 51 is annular, a plurality of stretching rings are arranged at the inner side annular opening edge of the shielding cloth 51, the pull rope 52 passes through the stretching rings in sequence, the two ends of the pull rope 52 are fixedly connected with the pulling block 54, the pulling block 54 is slidably connected with the top surface of the main rod 1, the pulling block 54 slides forward and backward along the main rod 1, the closing handle 55 is arranged at the rear side of the pulling block 54. In normal state, the shielding cloth 51 is folded and located at the top edge of the bag body 35 and is fixed by a belt, the two ends of the belt are connected with the bag body 35 respectively, the belt is a disposable structure and has poor toughness, the belt is pulled and torn when the pull rope 52 is pulled, so that the shielding cloth 51 is tightened. In use, the closing handle 55 is pulled backward, the pulling block 54 drives the pull rope 52 to move backward, and then the shielding cloth 51 is pulled open, the opening in the middle of the shielding cloth 51 is tightened and closed, so that the top opening of the bag body 35 is closed, which is convenient for subsequent crushing of the tissue and air extraction in the bag body 35 to reduce the volume.

[0052] The shielding cloth 51 is provided with a notch 511 at the edge, so as to avoid interference with the unfolding strip 36.

[0053] The squeezing assembly 6 is further arranged on both sides of the bag body assembly 3. Before the object bag is taken out, the bag body 35 is squeezed to reduce the volume.

[0054] The squeezing assembly 6 comprises a plurality of electromagnets 61, which are arranged in correspondence with each other at equal intervals from top to bottom along the left and right sides of the bag body 35. When the crushing and negative pressure suction of the tissue in the bag body 35 are completed, the electromagnets 61 are energized, the corresponding electromagnets 61 on both sides are attracted to each other, the bag body 35 on the inner side is squeezed to reduce the volume, and the bag body 35 is taken out from the laparoscope incision.

[0055] In use, the main rod is held by the medical staff, the front end of the main rod is inserted into the abdominal cavity of the patient from the laparoscope incision.

[0056] The medical staff holds the main rod, the front end of the main rod is inserted into the abdominal cavity of the patient from the laparoscope incision.

[0057] The bag opening strip, the bag body are pushed out of the main rod by the main connecting rod and the side connecting rod. When the bag opening strip is completely pushed out, the bag opening strip immediately restores the arc state to open the port of the bag body. The unfolding strip restores the shape to open the side wall of the bag body, so that the bag body is unfolded, at the same time, the bag body is unfolded to drive the extension plate to be unfolded, and then the extension plate is unfolded to drive the bottom of the bag body to be unfolded and flattened. At this time, the medical staff can put the removed tissue into the bag body.

[0058] After the tissue is bagged, the closure handle is pulled back, which pulls the pull cord back, which pulls the cover cloth open, and closes the opening in the middle of the cover cloth.

[0059] The motor is then activated, and the bag is crushed by the crushing blades. After the crushing is complete, the negative pressure source is activated, and the liquid and air inside the bag are removed, which causes the bag to tighten around the tissue. At this point, the push handle is pulled back, which pulls the main rod and the side rod, which pulls the bag opening and the bag back into the main rod, until it can't go any further. At this point, the bag opening is closed, and the bag is at its smallest size. The electromagnet is then activated, which further compresses the bag.

[0060] Finally, the bag is removed from the patient's laparoscopic incision.
