Description

Technical Field

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

[0002] In minimally invasive surgery, such as laparoscopic surgery, a specimen collection bag is inserted into the abdominal cavity from the wound, and the removed diseased tissue and other samples fall into the specimen collection bag. In the prior art, the specimen collection bag includes a clamp, a self-adhesive silicone sheet and a collection bag. The two sides of the collection bag are connected to the clamp through the self-adhesive silicone sheet. The clamp can be opened to open the opening of the collection bag, and the clamp can be closed to close the opening of the collection bag. However, since the abdominal wound in minimally invasive surgery is small, when the collection bag is pulled out of the abdominal cavity, the sample in the collection bag is squeezed and easily squeezed out from the opening, resulting in the doctor being unable to smoothly remove the specimen.

[0003] There is another specimen retrieval bag in the prior art, which includes a retrieval bag, a sleeve rod, and a structure disposed inside the sleeve rod. Before the retrieval bag enters the abdominal cavity, the retrieval bag is located inside the sleeve rod. After one end of the sleeve rod is inserted into the abdominal cavity, the retrieval bag is pushed out of the sleeve rod through the structure inside the sleeve rod, and the opening of the retrieval bag is propped open by an arc-shaped metal wire. After the sample is collected, the opening of the retrieval bag is contracted by the structure inside the sleeve tube to take the retrieval bag out. However, in the prior art, the structure inside the sleeve rod is complicated, resulting in a complicated structure of the specimen retrieval bag and high processing costs.

[0004] In addition, in the prior art, the specimen collection bag cannot be sealed after the sample is obtained, which may cause liquid to easily flow out from the opening.

[0005] In addition, there will be a large amount of gas occupying space in the specimen retrieval bag, resulting in a large volume of the specimen retrieval bag, and the specimen retrieval bag is difficult to remove from the surgical opening.

[0006] In addition, due to the limited space in the abdominal cavity, after the specimen retrieval bag is placed in the abdominal cavity, the structure that assists in opening and closing the retrieval bag (such as the structure inside the sleeve rod in the prior art) needs to be small in size so as not to cause secondary harm to the patient. The specimen retrieval bag in the prior art is difficult to meet this requirement. Utility Model Content

[0007] The utility model aims to provide a specimen collection bag to at least solve one of the above technical problems.

[0008] To achieve the above purpose, the utility model provides a specimen collection bag, comprising:

[0009] A bag body, wherein a first end of the bag body has an opening;

[0010] An auxiliary clamp, which is connected to the outer side of the first end of the bag body. When the jaws of the auxiliary clamp open, the opening can be opened, and when the jaws of the auxiliary clamp close, the opening can be closed;

[0011] A connecting component, which includes a slider, a first connecting strip, and a second connecting strip. The first connecting strip and the second connecting strip are connected to opposite sides of the first end of the bag body. The slider is slidably connected to the first end along the length direction of the first connecting strip to continuously squeeze the first connecting strip and the second connecting strip, so that the second connecting strip is connected to the first connecting strip;

[0013] Optionally, the first connecting strip and the second connecting strip are hermetically connected.

[0014] Optionally, the length of the auxiliary clamp facing the first end is less than the length of the first end. The first end includes a first section facing the auxiliary clamp and a second section not facing the auxiliary clamp;

[0015] When the slider is located at the starting end of the first end, the opening is opened. When the slider slides to the ending end of the first end, the opening is sealed. The starting end and the ending end are respectively the two ends of the first end along the length direction of the first connecting strip;

[0016] The drawstring assembly can drive the slider to slide from the starting end along the first section to the side where the ending end is located. The drawstring assembly can also fold the second section by a preset angle and drive the slider to move to the ending end at the folded second section.

[0017] Optionally, the bag body includes a first wall and a second wall that are relatively connected. One of the first connecting strip and the second connecting strip is connected to the first wall, and the other is connected to the second wall;

[0018] The drawstring assembly includes a first drawstring and a second drawstring. The first drawstring is connected to the side of the slider close to the first wall, and the second drawstring is connected to the side of the slider close to the second wall. The first drawstring can drive the slider to slide on the first section, and the second drawstring can drive the second section to fold and drive the slider to slide on the second section.

[0019] Optionally, the auxiliary clamp includes a first clamp rod and a second clamp rod that are rotatably connected. The first clamp rod includes a first clamping section, and the second clamp rod includes a second clamping section. The first clamp rod and the second clamp rod rotate around one end of the first clamping section and the second clamping section. The first clamping section is connected to the outer side of the first wall, and the second clamping section is connected to the outer side of the second wall.

[0020] Optionally, the length of the first clamping section is greater than the length of the second clamping section;

[0021] The first end further includes a transition section located between the first section and the second section. The transition section is located between the other end of the first clamping section and the other end of the second clamping section;

[0022] The pull rope assembly can slide the slider to the transition section and cause the second section and the slider to fold.

[0023] Optionally, the extending direction of the second pull rope forms an angle with the bag body, and the second pull rope gradually approaches the bag body from the side where the starting end is located to the side where the ending end is located; and / or

[0024] The second pull rope is connected to one end of the slider close to the ending end.

[0025] Optionally, the first clamping section is provided with a first limiting hole and a second limiting hole. The first limiting hole is opened at one end of the first clamping section, and the second limiting hole is opened at the other end of the first clamping section. The first pull rope passes through the first limiting hole and the second limiting hole and is connected to the slider; and / or

[0026] One end of the second clamping section is provided with a third limiting hole, and the second pull rope passes through the third limiting hole and is connected to the slider.

[0027] Optionally, the starting end and the ending end are sequentially away from the rotation center of the first clamp rod. The starting end is connected to the rotation center of the first clamp rod and / or the second clamp rod. After the second section is folded, the first end can abut against the other end of the second clamping section.

[0028] Optionally, when the first connecting strip and the second connecting strip are hermetically connected, the specimen retrieval bag further includes an exhaust assembly, and the exhaust assembly can discharge the air in the bag body.

[0029] Optionally, the bag body is provided with a pore. The exhaust assembly includes a breathable and water-impermeable film and an exhaust pipe. The breathable and water-impermeable film covers the pore, and one end of the exhaust pipe is connected to the outer side of the breathable and water-impermeable film.

[0030] As can be seen from the above, in the technical solution provided by the present utility model, when using the specimen retrieval bag, the bag body is wound around the auxiliary forceps and inserted into the abdominal cavity. Inside the abdominal cavity, the bag body automatically unwinds from the auxiliary forceps, or by opening the jaws of the auxiliary forceps, the bag body unwinds from the auxiliary forceps. When it is necessary to receive the specimen, the jaws of the auxiliary forceps are opened, and the opening can be opened. After the sample falls into the bag body, the jaws of the auxiliary forceps close, and the opening also closes accordingly (but the opening is not sealed). By the operator operating the pull rope assembly to drive the slider to slide along the length direction of the first connecting strip (the second connecting strip), the first connecting strip and the second connecting strip are connected, realizing the sealing of the opening, effectively preventing the sample from being squeezed out of the opening when the bag body is squeezed. Finally, the operator pulls the auxiliary forceps outwards, and then pulls the bag body out of the abdominal cavity.

[0031] By using the auxiliary forceps, the bag can be wound around the auxiliary forceps, thus facilitating the insertion of the bag body into the abdominal cavity. In addition, when a doctor operates the specimen retrieval bag in the prior art and needs to open the retrieval bag, it is necessary to push the structure inside the sleeve rod to push the retrieval bag out of the sleeve rod. It is not easy for the doctor to control the pushing stroke. However, for a doctor, he is very skilled in operating scissors, and the operation of the auxiliary forceps is similar to that of scissors. Therefore, it is easier for the doctor to control and operate the auxiliary forceps. In addition, in the prior art, the opening of the retrieval bag is opened by an arc-shaped wire. After the arc-shaped wire is pushed out from inside the sleeve rod, it automatically opens the opening, and the size of the opening is controlled by the radian size of the wire. The doctor cannot automatically control the size of the opening. In this embodiment, the doctor can control the opening degree of the jaws of the auxiliary forceps, and then control the size of the opening, and the operation is more flexible.

[0032] By using the pull rope assembly, it is more convenient for the doctor to operate the slider located inside the body outside the body. In addition, the pull rope assembly is flexible. Compared with the arc-shaped wire in the prior art, the pull rope assembly will not cause damage to the inner wall of the abdominal cavity. In addition, the pull rope assembly is easy to control, and the doctor can determine the closing degree of the opening according to needs.

[0033] The specimen retrieval bag provided by the present utility model has a simple structure, low cost, and the opening of the bag body can be sealed, thus preventing the sample from falling out of the opening. Description of the Drawings

[0056] Embodiment 1

[0057] This embodiment provides a specimen retrieval bag, which is used for collecting samples in laparoscopic surgery, but is not limited thereto, and can also be used in other minimally invasive surgical procedures to simplify the structure of the specimen retrieval bag, reduce costs, and avoid the easy outflow of liquid from the opening.

[0058] As Figures 1 - 5 shown, the specimen retrieval bag provided in this embodiment includes a bag body 1, a connection assembly 2, a drawstring assembly 4, and an auxiliary clamp 3. As Figure 1and Figure 4 As shown, the first end 11 of the bag body 1 has an opening. The connecting assembly 2 includes a slider 23, a first connecting strip 21, and a second connecting strip 22. The first connecting strip 21 and the second connecting strip 22 are connected to opposite sides of the first end 11 of the bag body 1. The slider 23 is slidably connected to the first end 11 along the length direction of the first connecting strip 21 to continuously squeeze the first connecting strip 21 and the second connecting strip 22, so that the second connecting strip 22 is connected to the first connecting strip 21, thereby closing the opening and preventing the sample in the bag body 1 from falling out of the opening. It can be understood that closing the opening is not the same as sealing the opening. After closing the opening, gas and a small amount of liquid can still enter and exit through the opening.

[0059] As Figure 1 shown, the auxiliary forceps 3 are connected to the outside of the first end 11 of the bag body 1. The opening of the jaws of the auxiliary forceps 3 can make the opening open, as Figure 2 shown, and the closing of the jaws of the auxiliary forceps 3 can make the opening close. As Figures 1 - 3 shown, the drawstring assembly 4 is connected to the slider 23 to drive the slider 23 to slide, thereby closing the opening.

[0060] When using the specimen retrieval bag, the bag body 1 is wound around the auxiliary forceps 3 and inserted into the abdominal cavity. Inside the abdominal cavity, the bag body 1 automatically unwinds from the auxiliary forceps 3, or by opening the jaws of the auxiliary forceps 3, the bag body 1 unwinds from the auxiliary forceps 3. When it is necessary to receive the specimen, the jaws of the auxiliary forceps 3 are opened, and the opening can be opened (as Figure 1 shown). After the sample falls into the bag body 1, the jaws of the auxiliary forceps 3 close, and the opening also closes accordingly (but the opening is not closed). By the operator operating the drawstring assembly 4 to drive the slider 23 to slide along the length direction of the first connecting strip 21 (the second connecting strip 22), the first connecting strip 21 and the second connecting strip 22 are connected, realizing the closing of the opening and effectively preventing the sample from being squeezed out of the opening when the bag body is squeezed. Finally, the operator pulls the auxiliary forceps 3 outwards, and then pulls the bag body 1 out of the abdominal cavity.

[0061] In this embodiment, by using the auxiliary forceps 3, the bag 1 can be wound around the auxiliary forceps 3, thus facilitating the insertion of the bag body 1 into the abdominal cavity. In addition, when a doctor operates the specimen retrieval bag in the prior art and needs to open the retrieval bag, the retrieval bag needs to be pushed out of the sleeve rod by pushing the structure inside the sleeve rod, and it is not easy for the doctor to control the pushing stroke. However, for a doctor, he is very skilled in operating scissors, and the operation of the auxiliary forceps 3 is similar to that of scissors. Therefore, it is easier for the doctor to control and operate the auxiliary forceps 3. In addition, in the prior art, the opening of the retrieval bag is opened by an arc-shaped wire. After the arc-shaped wire is pushed out from inside the sleeve rod, it automatically opens the opening, and the size of the opening is controlled by the radian size of the wire. The doctor cannot automatically control the size of the opening. In this embodiment, the doctor can control the opening degree of the jaws of the auxiliary forceps 3, and thus control the size of the opening, and the operation is more flexible.

[0062] In this embodiment, by using the drawstring assembly 4, it is more convenient for the doctor to operate the slider 23 located inside the body outside the body. In addition, the drawstring assembly 4 is flexible. Compared with the arc-shaped wire in the prior art, the drawstring assembly 4 will not cause damage to the inner wall of the abdominal cavity. In addition, the drawstring assembly 4 is easy to control, and the doctor can decide the degree of opening closure according to needs.

[0063] The specimen retrieval bag provided in this embodiment has a simple structure, low cost, and the opening of the bag body 1 can be closed, thus preventing the sample from falling out of the opening.

[0064] In this embodiment, the connecting assembly 2 is a male-female zipper in the prior art. Among them, the first connecting strip 21 can be a concave strip, the second connecting strip 22 can be a convex strip, a chute is provided in the slider 23, and the first end 11 is slidably inserted into the chute. The width of the chute is smaller than the sum of the thicknesses of the first end 11, the concave strip and the convex platform. The slider 23 is made of an elastic material such as rubber or silica gel. Slide the slider 23 along the length direction of the first connecting strip 21, and the chute of the slider 23 squeezes the concave strip and the convex strip, and the protrusion of the convex strip can be inserted into the groove of the concave strip, thereby sealing the opening. In other alternative embodiments, both the first connecting strip 21 and the second connecting strip 22 can also be pressure-sensitive adhesives. Sliding the slider 23 can squeeze the first connecting strip 21 and the second connecting strip 22, so that the first connecting strip 21 and the second connecting strip 22 are hermetically bonded. In another alternative embodiment, the connecting assembly 2 can also be a zipper. At this time, both the first connecting strip 21 and the second connecting strip 22 include a row of continuously arranged teeth, and the slider 23 is a zip fastener. Pulling the zip fastener can connect the teeth of the first connecting strip 21 and the second connecting strip 22. The structure of the zipper is substantially the same as that of the zippers in clothing, bags, etc. in the prior art. The zipper in this embodiment is preferably made of plastic, and the volume of the teeth can be small to reduce the volume of the entire specimen retrieval bag.

[0065] Preferably, the first connecting strip 21 and the second connecting strip 22 can be hermetically connected, so that the specimen retrieval bag seals the opening after obtaining the sample, preventing liquid from flowing out of the opening. At this time, the connecting assembly 2 is the above-mentioned male-female zipper, or both the first connecting strip 21 and the second connecting strip 22 are the above-mentioned pressure-sensitive adhesives, so as to seal the opening when the first connecting strip 21 and the second connecting strip 22 are connected. In this embodiment, the connecting assembly 2 is preferably the above-mentioned male-female zipper. The slider 23 of the male-female zipper slides smoothly, has a small sliding resistance, and a good sealing effect.

[0066] Such as Figures 1 - 3 and Figure 5As shown, the main structure of the auxiliary clamp 3 is generally similar to that of scissors or pliers in the prior art. Exemplarily, the auxiliary clamp 3 includes a first clamp rod 31 and a second clamp rod 32 that are rotatably connected. The first clamp rod 31 includes a first clamping section 311, and the second clamp rod 32 includes a second clamping section 321. The space between the first clamping section 311 and the second clamping section 321 is the jaws. The first clamp rod 31 and the second clamp rod 32 rotate around one end of the first clamping section 311 and the second clamping section 321.

[0067] Optionally, the auxiliary clamp 3 may further include a first fixed shaft 33, and the first clamp rod 31 and the second clamp rod 32 are rotatably connected to the first fixed shaft 33, that is, the first clamp rod 31 and the second clamp rod 32 rotate around the first fixed shaft 33.

[0068] Optionally, the first clamp rod 31 further includes a first operation section 312 connected to the first clamping section 311. For the convenience of distinction, the first clamp rod 31 takes the first fixed shaft 33 as the demarcation point. One side of the first fixed shaft 33 is the first clamping section 311, and the other side is the first operation section 312. The second clamp rod 32 further includes a second operation section 322 connected to the second clamping section 321. For the convenience of distinction, the second clamp rod 32 takes the first fixed shaft 33 as the demarcation point. One side of the first fixed shaft 33 is the second clamping section 321, and the other side is the second operation section 322. By holding and rotating the first operation section 312 and the second operation section 322, the first clamp rod 31 and the second clamp rod 32 can be rotated around the first fixed shaft 33, thereby opening and closing the jaws. Optionally, the auxiliary clamp 3 is made of plastic, which has a low cost and does not cause harm to the human body.

[0069] As Figures 1 - 4 shown, optionally, for the convenience of description, the two ends of the first end 11 along the length direction of the first connecting strip 21 are respectively named the starting end 111 and the ending end 112. As Figure 1 shown, when the slider 23 is located at the starting end 111 of the first end 11, the opening is open. As Figure 3 shown, when the slider 23 slides to the ending end 112 of the first end 11, the opening is sealed, that is, when the slider 23 slides from the starting end 111 to the ending end 112, the opening is sealed.

[0070] As Figures 1 - 3As shown, optionally, the length of the auxiliary clamp 3 facing the first end 11 of the bag body 1 is less than the length of the first end 11, that is, the lengths of the first clamping section 311 and the second clamping section 321 facing the first end 11 of the bag body 1 are less than the length of the first end 11. In the prior art, the clamp corresponds to the collection bag along the width direction, that is, the length of the clamp extending into the abdominal cavity is not less than the width of the collection bag, and the length of the clamp entering the abdominal cavity is relatively long. Compared with the clamp in the prior art, there is a section of length in the width direction of the bag body 1 in this embodiment that does not correspond to the auxiliary clamp 3, and the length of the auxiliary clamp 3 entering the abdominal cavity is less than the width of the bag body 1. The length of the auxiliary clamp 3 entering the abdominal cavity is relatively short, avoiding the auxiliary clamp 3 from contacting the abdominal cavity wall and thus avoiding secondary harm to the human body. Although the size of the bag body 1 is larger than the length of the auxiliary clamp 3 entering the abdominal cavity, since the bag body 1 is flexible, when it contacts the abdominal cavity wall, the bag body 1 can be folded, so it will not cause secondary harm to the human body.

[0071] As Figure 2 shown, for the convenience of description, the first end 11 is divided into a first section 113 and a second section 115. The first end 11 includes a first section 113 facing the auxiliary clamp 3 and a second section 115 not facing the auxiliary clamp 3. The drawstring assembly 4 can drive the slider 23 to slide from the starting end 111 along the first section 113 towards the side where the end 112 is located. The drawstring assembly 4 can also cause the second section 115 to be folded by a preset angle and drive the slider 23 to move to the end 112 at the folded second section 115.

[0072] That is to say, during the process of sealing the opening, as Figure 1 shown, first, the drawstring assembly 4 is pulled. The drawstring assembly 4 can drive the slider 23 to slide on the first section 113. When the slider 23 slides to the connection between the first section 113 and the second section 115, the second section 115 is not facing the auxiliary clamp 3. Since the bag body 1 is flexible, pulling the drawstring assembly 4 can cause the second section 115 to be folded (as Figure 3 shown), that is, to bend the bag body 1. Exemplarily, the second section 115 can be folded by approximately 180° until it is substantially parallel to the first section 113. Pulling the drawstring assembly 4 again can cause the slider 23 to slide on the second section 115 until the slider 23 moves to the end 112. As Figure 3 shown, it can be understood that after the second section 115 is folded, the first section 113 is still clamped between the first clamping section 311 and the second clamping section 321, the second clamping section 321 will be located between the first section 113 and the second section 115, and the other end of the second clamping section 321 will abut between the first section 113 and the second section 115.

[0073] Since the second section 115 is not connected to the auxiliary clamp 3, it is difficult for the slider 23 to continue sliding on the second section 115. In this embodiment, by folding the second section 115, the slider 23 can continue to slide at the folded second section 115 by pulling the slider 23.

[0074] As Figure 4 shown, optionally, the bag body 1 includes a first wall 12 and a second wall 13 that are oppositely connected. One of the first connecting strip 21 and the second connecting strip 22 is connected to the first wall 12, and the other is connected to the second wall 13.

[0075] As Figure 1 shown, the first clamping section 311 is connected to the outer side of the first wall 12, and the second clamping section 321 is connected to the outer side of the second wall 13. As Figure 4 shown and combined with Figure 1 , optionally, an insertion part 14 can be connected to the outer side of the first wall 12. The first clamping section 311 is inserted into the insertion part 14 to be connected to the first wall 12. An insertion part 14 can also be connected to the outer side of the second wall 13. The second clamping section 321 is inserted into the insertion part 14 to be connected to the second wall 13. The insertion part 14 can be a socket, and the insertion hole direction of the socket is consistent with the extending direction of the first clamping section 311 or the second clamping section 321. The first clamping section 311 and the second clamping section 321 can be inserted into the socket. Thus, when the jaws open, the first wall 12 and the second wall 13 are driven to move away from each other to open the opening, and when the jaws close, the first wall 12 and the second wall 13 are driven to move closer to each other to close the opening.

[0076] As Figures 1 - 3 and Figure 6 shown, the pulling rope assembly 4 includes a first pulling rope 41 and a second pulling rope 42. The first pulling rope 41 is connected to one side of the slider 23 close to the first wall 12, and the second pulling rope 42 is connected to one side of the slider 23 close to the second wall 13. The first pulling rope 41 can drive the slider 23 to slide on the first section 113, and the second pulling rope 42 can drive the second section 115 to fold and enable the slider 23 to slide on the second section 115.

[0077] By providing the first pulling rope 41 and the second pulling rope 42, the slider 23 can slide on the first section 113 and the folded second section 115 respectively, and drive the second section 115 to fold.

[0078] As Figure 2 、 Figure 3 and Figure 5 shown, the length of the first clamping section 311 is greater than the length of the second clamping section 321. As Figure 2As shown, the first end 11 further includes a transition section 114 located between the first section 113 and the second section 115. The transition section 114 is located between the other end of the first clamping section 311 and the other end of the second clamping section 321. The pull rope assembly 4 can slide the slider 23 to the transition section 114 and cause the second section 115 and the slider 23 to fold, that is, the slider 23 folds synchronously with the second section 115. The length difference between the first clamping section 311 and the second clamping section 321 is the same as the length of the transition section 114. As Figure 3 shown, in this embodiment, the length of the transition section 114 allows the transition section 114 to form an arc structure 1141 (the arc structure 1141 is the position where the first end 11 faces the other end of the second clamping section 321) and enables the slider 23 to also flip, so that the slider 23 can slide smoothly to the second section 115.

[0079] The length of the first clamping section 311 is greater than the length of the second clamping section 321. On the one hand, it reserves a flipping space for the second section 115. On the other hand, after the slider 23 slides to the transition section 114, it can flip synchronously with the second section 115. After flipping, it is convenient for the slider 23 to continue sliding along the second section 115.

[0080] As Figure 2 shown, optionally, the extending direction of the second pull rope 42 forms an angle with the bag body 1, and the second pull rope 42 gradually approaches the bag body 1 from the side where the starting end 111 is located to the side where the ending end 112 is located. Thus, when pulling the pull rope, the pull rope can apply a folding component force perpendicular to the surface of the bag body 1 to the slider 23, thereby causing the slider 23 to fold, and the slider 23 drives the second section 115 to fold.

[0081] To facilitate defining the extending direction of the second pull rope 42, optionally, a third limiting hole 323 is provided at one end of the second clamping section 321. The second pull rope 42 passes through the third limiting hole 323 and is connected to the slider 23. The extending direction of the connection line between the third limiting hole 323 and the slider 23 is generally the extending direction of the second pull rope 42. Thus, the third limiting hole 323 ensures that the second pull rope 42 is inclined relative to the bag body 1, ensures that the second pull rope 42 applies a folding component force perpendicular to the surface of the bag body 1 to the slider 23. At the same time, after the second section 115 flips, the third limiting hole 323 can also define the force application direction of the second pull rope 42 on the slider 23 to ensure that the slider 23 slides on the second section 115. In addition, the third limiting hole 323 can also standardize the position of the second pull rope 42, facilitate the operator to quickly determine the second pull rope 42 among the two pull ropes, and prevent the second pull rope 42 from knotting and from winding around the first pull rope 41.

[0082] As Figure 5 and Figure 6As shown, optionally, the end of the second drawstring 42 not connected to the slider 23 passes through the third limiting hole 323 and extends to the first operation section 312, facilitating the operator to apply a pulling force to the second drawstring 42. Optionally, the end of the second drawstring 42 not connected to the slider 23 can also be connected to the second pull ring 44, facilitating the operator to apply a pulling force to the second drawstring 42 through the second pull ring 44.

[0083] As Figure 5 shown, in this embodiment, the second clamping section 321 is inclined with respect to the bag body 1. The second clamping section 321 gradually approaches the bag body 1 from the side where the starting end 111 is located to the side where the ending end 112 is located. The extending direction of the second clamping section 321 is generally consistent with the extending direction of the second drawstring 42, making it easier for the position of the third limiting hole 323 to meet the requirements.

[0084] Furthermore, the second drawstring 42 is connected to one end of the slider 23 close to the ending end 112. In this way, the second drawstring 42 applies a folding component force to one end of the slider 23 close to the ending end 112, making it easier for the slider 23 to flip, and the slider 23 is also easier to drive the transition section 114 and the second section 115 to flip.

[0085] As Figure 4 and Figure 6 shown, the first clamping section 311 is provided with a first limiting hole 313 and a second limiting hole 314. The first limiting hole 313 is opened at one end of the first clamping section 311, and the second limiting hole 314 is opened at the other end of the first clamping section 311. The first drawstring 41 passes through the first limiting hole 313 and the second limiting hole 314 and is connected to the slider 23.

[0086] Optionally, the end of the first drawstring 41 not connected to the slider 23 passes through the first limiting hole 313 and extends to the second operation section 322, facilitating the operator to apply a pulling force to the first drawstring 41. Optionally, the end of the first drawstring 41 not connected to the slider 23 can also be connected to the first pull ring 43, facilitating the operator to apply a pulling force to the first drawstring 41 through the first pull ring 43.

[0087] As Figure 2 shown, to further ensure the smooth sliding of the slider 23, optionally, the starting end 111 and the ending end 112 are successively away from the rotation center of the first clamping rod 31. The starting end 111 is connected to the rotation center of the first clamping rod 31 (the second clamping rod 32). Thus, when the slider 23 slides towards the side where the ending end 112 is located in the first section 113, the bag body 1 is tightened, and the slider 23 can slide smoothly.

[0088] As Figure 4As shown, optionally, the bag body 1 further includes a connecting belt 15. One end of the connecting belt 15 is connected to the starting end 111, and the other end is connected to the first fixed shaft 33. Optionally, a collar 16 may also be connected to the other end of the connecting belt 15, and the collar 16 is sleeved outside the first fixed shaft 33 to realize the connection between the connecting belt 15 and the first fixed shaft 33.

[0089] Of course, the slider 23 can also slide smoothly by connecting and tightening the bag body 1 through the first clamping section 311 and the second clamping section 321 with the insertion part 14.

[0090] As Figure 3 shown, after the second section 115 is folded, the first end 11 can abut against the other end of the second clamping section 321. Specifically, the arc-shaped structure 1141 abuts against the other end of the second clamping section 321. At this time, the second clamping section 321 is clamped between the first section 113 and the second section 115, and the other end of the second clamping section 321 can press tightly against the first section 113. Thus, when the slider 23 slides towards the end 112 at the second section 115, the second clamping section 321 can tension the second section 115. When pulling the second drawstring 42, it can effectively prevent the first end 11 from sliding with the slider 23, and further enable the slider 23 to slide smoothly at the second section 115.

[0091] The specimen retrieval bag further includes an exhaust assembly 5. The exhaust assembly 5 can exhaust the air in the bag body 1, so that the volume of the bag body 1 is small and it is convenient to pull the bag body 1 out of the abdominal cavity.

[0092] An air hole is formed in the bag body 1. The exhaust assembly 5 includes a breathable and water-impermeable membrane 52 and an exhaust pipe 51. The breathable and water-impermeable membrane 52 covers the air hole, and one end of the exhaust pipe 51 is connected to the outside of the breathable and water-impermeable membrane 52. The breathable and water-impermeable membrane 52 can allow the air in the bag body 1 to enter the exhaust pipe 51, but does not allow the liquid in the bag body 1 to enter the exhaust pipe 51, thereby avoiding the outflow of the liquid in the bag body 1 when evacuating the bag body 1, and at the same time, the air in the bag body 1 can be emptied. The specific molecular structure and composition of the breathable and water-impermeable membrane 52 are prior art and will not be elaborated here.

[0093] Optionally, the other end of the exhaust pipe 51 can be connected to a vacuum pumping component such as a vacuum pump, so that the vacuum pumping component pumps out the air in the bag body 1 through the exhaust pipe 51.

[0094] The process of using the specimen retrieval bag provided in this embodiment is as follows:

[0095] Close the jaws, wind the bag body 1 around the first jaw 31 and the second jaw 32, and insert the first clamping section 311, the second clamping section 321 and the bag body 1 into the abdominal cavity through the wound;

[0096] The space in the abdominal cavity increases relative to the wound space, and the bag body 1 automatically bypasses the first clamp rod 31 and the second clamp rod 32;

[0097] The operator controls the first operating section 312 and the second operating section 322 to move the first clamp rod 31 and the second clamp rod 32 away from each other, the jaws open, and the opening of the bag body 1 opens accordingly;

[0098] The sample falls into the bag body 1 from the opening;

[0099] The operator controls the first operating section 312 and the second operating section 322 to move the first clamp rod 31 and the second clamp rod 32 closer to each other, the jaws are closed, and the opening of the bag body 1 is closed accordingly;

[0100] The operator pulls the first drawstring 41, and the slider 23 slides toward the side where the end 112 is located under the pulling force of the first drawstring 41, until it slides to the transition section 114, that is, the slider 23 slides to a position roughly opposite to the second limiting hole 314; the operator pulls the second drawstring 42, and the second drawstring 42 applies a component force perpendicular to the bag body 1 to the slider 23, so that the second section 115 and the slider 23 are folded approximately 180°. After the second section 115 is folded, the operator continues to pull the second drawstring 42, and the slider 23 continues to slide toward the side where the end 112 is located, until it slides to the end 112 and the opening is sealed;

[0101] The vacuum pump is connected to the exhaust pipe 51 to extract the air in the bag body 1;

[0102] The operator pulls the bag body 1 out of the patient's abdominal cavity by pulling the first operating section 312 and the second operating section 322 .

[0103] Embodiment 2

[0104] like Figure 7 and Figure 10 As shown, the main difference between the specimen retrieval bag of the second embodiment and the above-mentioned first embodiment is that the specific structures of the auxiliary forceps 3 and the pull rope assembly 4 are different.

[0105] like Figure 7 and Figure 8 As shown, in this embodiment, the end 112 and the beginning 111 of the first end 11 are respectively away from the rotation center of the first clamp rod 31 and the second clamp rod 32, and the first clamp rod 31 and the second clamp rod 32 extend to the beginning 111 of the first end 11. That is, the length of the auxiliary clamp 3 facing the first end 11 of the bag body 1 is equal to the length of the first end 11.

[0106] like Figure 7 and Figure 9As shown, optionally, when the jaws are opened, in order to ensure that the opening is opened at all places, the first clamping section 311 may include a first rod 3111 and a second rod 3112, and the second clamping section 321 may include a third rod 3211 and a fourth rod 3212. One end of the first rod 3111 and one end of the third rod 3211 are the rotation centers of the first jaw rod 31 and the second jaw rod 32. One end of the first rod 3111 is rotatably connected to one end of the third rod 3211. The other end of the first rod 3111 is rotatably connected to one end of the second rod 3112. The other end of the third rod 3211 is rotatably connected to one end of the fourth rod 3212. The other end of the second rod 3112 is rotatably connected to the other end of the fourth rod 3212. Optionally, the other end of the third rod 3211 and one end of the fourth rod 3212 are rotatably connected by a second fixed shaft 35. The first rod 3111, the second rod 3112, the third rod 3211 and the fourth rod 3212 form a parallelogram link structure. When the jaws are opened, the opening is opened. When the jaws are closed, the opening is closed.

[0107] Optionally, a fourth limit hole 34 is provided on the first fixed shaft 33 of the auxiliary clamp 3. The pull rope assembly 4 slidably passes through the fourth limit hole 34, thereby standardizing the position of the pull rope assembly 4. At the same time, the force application direction of the pull rope assembly 4 on the slider 23 is limited to ensure that the slider 23 slides along the first section 113.

[0108] In this embodiment, optionally, the pull rope assembly 4 includes a third pull rope 45. One end of the third pull rope 45 is connected to the side of the slider 23 close to the first wall 12, and the other end is connected to the side of the slider 23 close to the second wall 13. The middle of the third pull rope 45 passes through the fourth limit hole 34 and extends between the first operation section 312 and the second operation section 322, so as to facilitate the operator to pull the third pull rope 45.

[0109] As Figure 10 shown, different from the first embodiment, in this embodiment, the insertion part 14 includes a first insertion sleeve 141 and a second insertion sleeve 142 arranged at intervals along the length direction of the first connecting strip 21. Among them, the first rod 3111 is inserted into the first insertion sleeve 141 connected to the first wall 12, and the second rod 3112 is inserted into the second insertion sleeve 142 connected to the first wall 12. The third rod 3211 is inserted into the first insertion sleeve 141 connected to the second wall 13, and the fourth rod 3212 is inserted into the second insertion sleeve 142 connected to the second wall 13.

[0110] Similar to Embodiment 1, in this embodiment, when the slider 23 is located at the starting end 111, the opening is opened, and when the slider 23 is located at the ending end 112, the opening is sealed; in this embodiment, the starting end 111 is connected to the other ends of the first clamping rod 31 and / or the second clamping rod 32. Specifically, the starting end 111 is connected to the other ends of the second rod 3112 and the fourth rod 3212. In this way, when the pulling rope assembly 4 pulls the slider 23 towards the side where the ending end 112 is located, the first clamping rod 31 and the second clamping rod 32 can tighten the first end 11, so that the slider 23 can slide towards the side where the ending end 112 is located under the pulling force of the pulling rope assembly 4. Optionally, the collar 16 on the bag body 1 can be sleeved on the second fixed shaft 35, so that the starting end 111 is connected to the auxiliary clamp 3 through the collar 16 and the connecting belt 15.

[0111] Compared with Embodiment 1, in this Embodiment 2, the lengths of the first clamping rod 31 and the second clamping rod 32 entering the abdominal cavity are long, and a relatively large space in the abdominal cavity is required. When the space in the abdominal cavity is small, the first clamping rod 31 and the second clamping rod 32 may touch the cavity wall of the patient's abdominal cavity, causing secondary harm to the patient.

[0112] The process of using the specimen retrieval bag provided in this embodiment is as follows:

[0113] The jaws are closed, the bag body 1 is wound around the first clamping rod 31 and the second clamping rod 32, and the first clamping rod 31 and the second clamping rod 32 penetrate into the abdominal cavity through the wound with the bag body 1.

[0114] The space in the abdominal cavity increases relative to the space of the wound, and the bag body 1 automatically unwinds from the first clamping rod 31 and the second clamping rod 32.

[0115] The operator controls the first operating section 312 and the second operating section 322 to move the first clamping rod 31 and the second clamping rod 32 away from each other, the jaws open, and the opening of the bag body 1 opens accordingly.

[0116] The sample falls into the bag body 1 through the opening.

[0117] The operator controls the first operating section 312 and the second operating section 322 to move the first clamping rod 31 and the second clamping rod 32 closer to each other, the jaws close, and the opening of the bag body 1 closes accordingly.

[0118] The operator pulls the third pulling rope 45, and the slider 23 slides towards the side where the ending end 112 is located under the pulling force of the third pulling rope 45 until it slides to the ending end 112, and the opening is sealed.

[0119] The vacuum pumping component is connected to the exhaust pipe 51 to pump out the air in the bag body 1.

[0120] The operator pulls the first operating section 312 and the second operating section 322 to pull the bag body 1 out of the patient's abdominal cavity.

[0121] Although the present utility model has been described in detail above with general descriptions, specific embodiments and experiments, some modifications or improvements can be made to it on the basis of the present utility model, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
