[0002] Laparoscopic surgery is a minimally invasive surgery performed through a small incision. It has the advantages of less trauma, less bleeding, and faster recovery, which brings good news to surgical patients. More and more surgeries can be completed under thoracoscopy or laparoscopy. It has been widely used in thoracic surgery, general surgery, hepatobiliary surgery, gynecology and other surgical fields. For such surgeries, how to safely and smoothly remove the removed tissue or local organ tissue from the patient's body without causing incision contamination during thoracic or laparoscopic surgery has become an important part of the surgery.

[0003] To address this problem, the traditional approach is to use sterile gloves or sterile saline bags to make bags after appropriate cutting and adjustment. During the operation, the bag is placed through the incision into the chest or abdominal cavity, and multiple forceps are used to repeatedly clamp and pull the edge of the bag opening in the cavity to stretch the bag opening before the excised tissue can be placed in the bag. The procedure is cumbersome and time-consuming, and it is inconvenient for doctors to operate, and it may even delay precious time to rescue patients. Improper operation during the operation may also cause tumor cells to fall off and remain.

[0004] Currently, there is also a method of using laparoscopic retrieval bags to remove tissues. However, for larger tissues, it is difficult to remove them using laparoscopic retrieval bags, which can easily cause implantation. Summary of the invention

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0026] like Figure 1 and Figure 2 As shown: in order to be able to mince the stored specimen 8 in the abdominal cavity, ensure the safety of the specimen 8 during the mincing process, and realize the convenient and safe removal of the resected specimen 8, the present invention includes a sleeve 1, a specimen bag 4 for storing the resected specimen 8, and an operating rod body 2 arranged in the sleeve 1; the bag mouth of the specimen bag 4 is assembled to the head end of the operating rod body 2 through an elastic body 5; the specimen bag 4 and the elastic body 5 can be contracted and located in the head end of the sleeve 1, and the specimen bag 4 and the elastic body 5 can be pushed out of the head end of the sleeve 1 through the operating rod body 2, and the bag mouth of the specimen bag 4 located outside the head end of the sleeve 1 can be opened through the elastic body 5; when the bag mouth of the specimen bag 4 is in the open state, the elastic body 5 can be separated from the bag mouth of the specimen bag 4 by pulling the operating rod body 2;

[0027] The bag opening tightening body is also included, which is adapted to be connected with the bag opening of the specimen bag 4, and a bag body connecting tube 3 is arranged on the upper part of the specimen bag 4, and the bag body connecting tube 3 is connected with the specimen bag 4; after the bag opening of the specimen bag 4 is in an open state and the elastic body 5 is separated from the bag opening of the specimen bag 4, the bag opening tightening body can be used to shrink and tighten the bag opening of the specimen bag 4;

[0028] A video positioning one-way valve 6 that allows the video head 13 to be inserted unidirectionally and is sealed is set at the end of the bag body connecting tube 3 away from the specimen bag 4. The video head 13 can enter the specimen bag 4 through the video positioning one-way valve 6 and the bag body connecting tube 3 to obtain video information in the specimen bag 4.

[0029] Specifically, the sleeve 1, the operating rod 2, the specimen bag 4 and the elastic body 5 are all made of materials that meet medical standards. The sleeve 1 is tubular, and the operating rod 2 is located inside the sleeve 1. Generally, the operating rod 2 and the sleeve 1 are coaxially distributed, and the operating rod 2 can move along the length direction of the sleeve 1 inside the sleeve 1. The specimen 8 after resection can be stored through the specimen bag 4, that is, the specimen 8 after resection can enter the specimen bag 4. When used specifically, the entire retrieval bag needs to be introduced into the abdominal cavity through a laparoscope. Therefore, before entering the abdominal cavity, the specimen bag 4 and the elastic body 5 need to be retracted and located in the head end of the sleeve 1, which can ensure that the specimen bag 4 and the elastic body 5 are smoothly placed in the abdominal cavity. When the specimen 8 needs to be stored, the specimen bag 4 and the elastomer 5 need to be pushed out of the head end of the sleeve 1 by operating the rod body 2. When the elastomer 5 is outside the sleeve 1, the elastic energy of the elastomer 5 itself is used to make the bag mouth of the specimen bag 4 in an open state. The specimen bag 4 with the bag mouth in an open state can store the specimen 8 after resection.

[0030] In the embodiment of the present invention, in order to facilitate the subsequent shredding of the specimen 8 in the specimen bag 4, when the bag opening of the specimen bag 4 is in an open state, the elastic body 5 needs to be separated from the bag opening of the specimen bag 4. In specific implementation, the elastic body 5 includes two C-shaped elastic connectors 10, and the two C-shaped elastic connectors 10 are installed at the head end of the operating rod body 2, such as Figure 3 As shown. Two elastic connectors 10 can be connected to the bag opening of the specimen bag 4. When the elastic connectors 10 are opened, the bag opening of the specimen bag 4 can be opened. The two elastic connectors 10 are sleeved on the bag opening of the specimen bag 4 and partially overlap. When the operating rod body 2 is pulled toward the tail end of the sleeve 1, since the two connectors 10 are in a non-closed state, the elastic body 5 can be separated from the bag opening of the specimen bag 4 as the operating rod body 2 is pulled. After the elastic body 5 is separated from the bag opening of the specimen bag 4, the operating rod body 2 needs to be withdrawn from the sleeve 1, that is, the operating rod body 2 and the elastic body 5 do not need to be used in subsequent operations.

[0031] In the embodiment of the present invention, after the elastic body 5 is separated from the bag opening of the specimen bag 4, the bag opening tightening body can still be used to tighten the bag opening of the specimen bag 4, so as to prepare for the subsequent shredding of the specimen 8 in the specimen bag 4. After the bag opening of the specimen bag 4 is tightened by the bag opening tightening body, the shredded specimens 8 can be prevented from escaping from the bag opening of the specimen bag 4. A video positioning one-way valve 6 is also provided on the specimen bag 4, and the video head 13 can enter the specimen bag 4 through the radio frequency positioning one-way valve 6, so as to collect video information in the specimen bag 4, and provide an operating basis for shredding the specimen 8 in the specimen bag 4. When the specimen 8 in the specimen bag 4 is shredded, the one-way operation and sealing characteristics of the video positioning one-way valve 6 can be used to maintain a sealed state, that is, when the video information is collected by the video head 13, the shredded specimen 8 is prevented from escaping from the specimen bag 4 through the joint of the bag body connecting tube 3, thereby ensuring the safety and reliability of the shredding process of the specimen 8. Generally, the video head 13 also needs to be connected to a display, and the video information collected by the video head 13 can be displayed and output through the display.

[0032] Furthermore, an inflation joint 9 for inflating the specimen bag 4 is provided on the bag body connecting tube 3 , and the inflation joint 9 is located between the video positioning one-way valve 6 and the specimen bag 4 .

[0033] In the embodiment of the present invention, the opening of the video positioning one-way valve 6 and the bag opening of the specimen bag 4 are arranged through the bag body connecting tube 3 to form a double opening structure. The inflation connector 9 can be connected to the specimen bag 4 through the bag body connecting tube 3. When the specimen bag 4 is inflated, the inflation connector 9 can be used to maintain the inflated state of the specimen bag 4. Of course, when the specimen bag 4 needs to be deflated, the inflation connector 9 is also needed. The inflation connector 9 can be in the form of a solenoid valve, etc., which can be selected according to needs and will not be repeated here.

[0034] After the specimen bag 4 is separated from the elastic body 5 in the abdominal cavity, in order to facilitate the subsequent shredding of the specimen 8, it is generally necessary to put the specimen bag 4 in an inflated state, that is, to provide an operating space for the breaker 12. When the specimen bag 4 needs to be inflated, the inflatable joint 9 can be used to inflate the specimen bag 4, and the video positioning one-way valve 6 can only allow the video head 13 to enter the specimen bag 4 from the outside, that is, the gas entering the specimen bag 4 will not escape through the video positioning one-way valve 6. Similarly, when the bag opening of the specimen bag 4 is tightened by the bag opening tightening body, the gas in the specimen bag 4 will not be discharged through the bag opening of the specimen bag 4, ensuring the stability of the gas in the specimen bag 4 after the specimen bag 4 is inflated, thereby providing effective protection for the operation of the breaker 12 in the specimen bag 4. When the gas in the specimen bag 4 needs to be released, the gas in the specimen bag 4 is released and discharged through the inflatable joint 9, which facilitates the removal of the specimen bag 4 from the abdominal cavity.

[0035] Furthermore, the bag opening tightening body includes a tightening wire body 7 which is adaptably connected to the bag opening of the specimen bag 4 and is independent of the elastic body 5. The end of the tightening wire body 7 is located outside the tail end of the sleeve 1. The bag opening of the specimen bag 4 can be tightened by the tightening wire body 7.

[0036] In an embodiment of the present invention, the bag opening tightening body adopts a tightening wire body 7, which passes through the bag opening of the specimen bag 4. The two ends of the tightening wire body 7 are located outside the tail end of the sleeve 1. The tightening wire body 7 is specifically made of a material that meets medical standards. By pulling the ends of the tightening wire body 7, the bag opening of the specimen bag 4 can be contracted and tightened.

[0037] In specific implementation, a rod through hole is set in the operating rod body 2, and the rod through hole is distributed along the length direction of the operating rod body 2 and passes through the operating rod body 2. The wire end of the tightening wire body 7 passes through the rod through hole and is located outside the tail end of the sleeve 1.

[0038] In the embodiment of the present invention, the tightening wire body 7 can be placed by operating the rod body through hole in the rod body 2. Of course, the main body of the tightening wire body 7 can also be located between the outer wall of the operating rod body 2 and the inner wall of the sleeve 1. The specific selection can be made according to needs. When the elastic body 5 is separated from the bag opening of the specimen bag 4 by operating the rod body 2, the normal use of the tightening wire body 7 will not be affected.

[0039] like Figure 5 and Figure 6 As shown, a storage capsule 15 for storing the chopped specimen 8 is disposed at the bottom of the specimen bag 4 , and the storage capsule 15 is communicated with the specimen bag 4 .

[0040] In the embodiment of the present invention, the storage capsule 15 is in the shape of a strip and is located at the bottom of the specimen bag 4. The shredded specimens 8 in the specimen bag 4 can be stored in the storage capsule 15 to prevent the shredded specimens 8 from clumping in the specimen bag 4, thereby improving the reliability of taking out the shredded specimens 8.

[0041] During specific implementation, the outer diameter of the storage bag 15 after inflation is much smaller than the inner diameter of the specimen bag 4 after inflation, and an exhaust pipe 16 for exhaust is also provided in the storage bag 15, one end of the exhaust pipe 16 is located in the storage bag 15, and the other end of the exhaust pipe 16 is located in the specimen bag 4, and the exhaust pipe 16 is fixed on the corresponding inner walls of the storage bag 15 and the specimen bag 4.

[0042] In the embodiment of the present invention, the storage capsule 15 is in the shape of a long strip after being inflated, and the outer diameter of the storage capsule 15 is much smaller than the inner diameter of the specimen bag 4, that is, the shredded specimen 8 is in the shape of a long strip in the storage capsule 15, which is convenient for pulling out the entire specimen bag 4. In order to facilitate the placement of the shredded specimen 8 in the storage capsule 15, an exhaust pipe 16 is arranged in the storage capsule 15, and the length of the exhaust pipe 16 in the storage capsule 15 is smaller than the length of the storage capsule 15. The two ends of the exhaust pipe 16 are respectively located in the storage capsule 15 and the specimen bag 4. The exhaust pipe 16 is fixed to the storage capsule 15 and the specimen bag 4 by bonding or the like. When the shredded specimen 8 enters the storage capsule 15, the gas in the storage capsule 15 is discharged through the exhaust pipe 15, which facilitates the shredded specimen 8 to smoothly enter the storage capsule 15.

[0043] Furthermore, after the elastic body 5 is separated from the bag opening of the specimen bag 4, a breaker 12 for breaking the specimen 8 in the specimen bag 4 is placed in the specimen bag 4 through the bag opening of the specimen bag 4, and the bag opening of the specimen bag 4 is tightened on the breaker 12 by utilizing the bag opening tightening energy.

[0044] In the embodiment of the present invention, the breaker 12 can adopt the existing commonly used structural form. The breaker 12 can be used to shred the specimens 8 in the specimen bag 4. After the larger specimens 8 are shredded, the shredded specimens 8 can be easily taken out of the specimen bag 4.

[0045] When used specifically, the specimen bag 4 is placed in the abdominal cavity through a laparoscope or the like, and the bag opening of the specimen bag 4 in the abdominal cavity is opened by the elastic body 5 so that the specimen 8 after resection can be stored in the specimen bag 4. The bag body connecting tube 3 connected to the specimen bag 4 can be pulled out of the abdominal wall 11 by clamping or the like, that is, the video positioning one-way valve 6 and the inflation joint 9 on the bag body connecting tube 3 are both located outside the abdominal wall 11. After the specimen 8 is stored, the elastic body 5 is separated from the bag opening of the specimen bag 4 by using the operating rod body 2. After the elastic body 5 is separated from the bag opening of the specimen bag 4, the operating rod body 2 and the sleeve 1 are removed, and the breaker 12 that passes through the abdominal wall 11 is extended into the specimen bag 4 through the bag opening of the specimen bag 4, and the video head 13 is inserted into the specimen bag 4 through the bag body connecting tube 3 and the video positioning one-way valve 6.

[0046] When the breaker 12 is inserted into the specimen bag 4 , the tightening wire 7 is used to tighten the bag opening of the specimen bag 4 , and the inflation tube 14 connected to the inflation connector 9 is connected to an external gas source to inject the required gas into the specimen bag 4 .

[0047] When the specimen bag 4 is inflated, the specimen 8 in the specimen bag 4 can be effectively shredded by the shredder 12 according to the video information obtained by the video head 13. The shredded specimen 8 is located at the bottom of the specimen bag 4. Figure 4 As shown, or located in the storage capsule 15, as Figure 6 After the specimen 8 in the specimen bag 4 is shredded, the video head 13 and the breaker 12 are withdrawn from the specimen bag 4, and the gas in the specimen bag 4 is released and discharged through the inflation joint 9, so that the shredded specimen 8 can be taken out of the specimen bag 4. During the shredding process of the specimen 8, a fully enclosed state is adopted, which will not cause planting and is safe and reliable.
