Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a laparoscopic gallbladder retrieval bag. Background Technology

[0002] With the continuous advancement of minimally invasive surgical techniques, laparoscopic surgery has gradually replaced many traditional open surgeries. Laparoscopic gallbladder retrieval bags are crucial tools for safely removing gallbladder specimens during minimally invasive surgery. In traditional laparoscopic cholecystectomy, removing the gallbladder through a small 10mm incision presents both challenges and risks. Without a retrieval bag, inflammatory exudation from the gallbladder wall can lead to abdominal incision infection and poor healing; if cancer is present in the gallbladder wall, it may cause dissemination of malignant tumors through the abdominal incision and within the abdominal cavity; furthermore, the manipulation of forceps during gallbladder removal can cause gallbladder rupture, bile leakage, and complications. Using commercially available retrieval bags to remove the gallbladder from the abdominal cavity often results in the gallbladder becoming curled up inside the bag, increasing the difficulty of laparoscopic removal and prolonging the surgery and anesthesia time, thus significantly increasing the patient's surgical risks and anesthetic burden. If stone removal is unsuccessful, a longer incision is often chosen, leading to increased surgical trauma and hindering the implementation of minimally invasive principles. Utility Model Content

[0003] The purpose of this invention is to provide a laparoscopic gallbladder retrieval bag, which solves the problems existing in the background art, greatly reduces the difficulty and risk of gallbladder or gallstone removal, and significantly increases the efficiency of retrieval. The specific technical solution adopted is as follows:

[0004] This utility model discloses a laparoscopic gallbladder retrieval bag, which includes a gallbladder duct loop device and a gallbladder retrieval device.

[0005] The gallbladder duct snare device consists of an outer tube fixing device, a snare wire, and an inner tube.

[0006] The gallbladder removal device comprises an outer tube, an inner tube pushing device, a medical elastic material skeleton retrieval bag, and a closing connecting line.

[0007] Preferably, the external tube fixation device consists of an external tube fixation device cap and an external tube fixation device body, which are connected vertically. The external tube fixation device cap can be fixed to the trocar port of the laparoscopy; the external tube fixation device body provides support and passage for the internal tube and the snare suture.

[0008] Preferably, the snare is a continuous line, divided into a snare loop, a snare knot, a middle snare, and a tail loop from beginning to end. The snare knot is a slipknot, allowing for free extension and retraction. The tip of the inner tube presses against the snare knot, enabling the snare loop to gradually tighten. The inner tube is open at both ends, with the middle snare passing through it. The inner tube also provides support for the snare and directs the snare knot in the direction of contraction when the snare loop is closed. When removing the gallbladder from the abdominal cavity, the snare loop of the cystic duct snare device is used to gradually tighten and secure the cystic duct, facilitating gallbladder removal.

[0009] Preferably, the outer tube of the gallbladder removal device is connected to the upper and lower parts, providing an outer sheath for the medical elastic material skeleton retrieval bag and a channel for the inner tube pushing device.

[0010] Preferably, the medical elastic material skeleton retrieval bag consists of three medical elastic material skeletons, an outer medical transparent plastic bag, a fixing plastic sleeve, an internal connecting channel, and a closing connecting line. The medical elastic material skeleton is flat in the middle, sheet-like, gradually becoming cylindrical towards both ends, with blunt elliptical ends to prevent the ends from piercing the outer medical transparent plastic bag. The three medical elastic material skeletons are of the same material, length, and shape, each with a central connecting hole at its flattened position. These three holes can be stacked and secured with rope or small screws. The material of the medical elastic material skeleton can be carbon fiber, medical elastic steel wire, or medical polymer material. The three medical elastic material skeletons are fixedly connected through the central connecting holes, with each skeleton forming a 60° angle. The fixing plastic sleeve is fixed to the outer medical transparent plastic bag and restrains the movement and position of the medical elastic material skeleton, allowing it to move up and down but preventing lateral deviation. The outer layer of the medical transparent plastic bag is folded back and fixed to create a channel for the connecting wire inside the retrieval bag. The retrieval bag can be closed using the connecting wire. The connecting wire channel inside the retrieval bag is higher than the head end of the medical elastic material skeleton. Tightening the opening of the retrieval bag can completely cover the head end of the medical elastic material skeleton.

[0011] Preferably, the inner tube pushing device in the gallbladder removal device is a hollow tube closed at one end. The head end of the inner tube pushing device has a pushing plane with a wire hole in the middle, which can form a sufficient contact surface with the medical elastic material skeleton retrieval bag. The tail end of the inner tube pushing device is a closed inner tube fixing pull ring. There is a tail end wire hole on each of the left and right sides below the inner tube fixing pull ring. The closing connection wire can be connected to the medical elastic material skeleton retrieval bag through the inner tube fixing pull ring, the tail end wire hole, the middle part of the inner tube pushing device, and the head end wire hole of the inner tube pushing device. When using a retrieval bag to remove gallbladder or stones, the outer tube is inserted into the laparoscopic trocar. By pushing the inner tube fixing ring, the inner tube pushing device pushes the medical elastic material skeleton retrieval bag downwards, eventually pushing the medical elastic material skeleton retrieval bag completely into the abdominal cavity. Once inside the abdominal cavity, the medical elastic material skeleton retrieval bag will automatically open completely due to the characteristics of its material, allowing stones or gallbladders that have been fixed with a cystic duct loop device to be placed into the medical elastic material skeleton retrieval bag.

[0012] Preferably, the closing connecting line is a single, continuous line, which is artificially divided into an inner connecting line inside the retrieval bag, a connecting line for the inner tube pushing device body, and a connecting line for the inner tube fixing pull ring, depending on their positions. By pulling the connecting line at the inner tube fixing pull ring, the connecting line for the inner tube pushing device body is gradually tightened, closing the bag and completely enclosing the head end of the medical elastic skeleton, allowing it to be removed together with the surgical specimen through the laparoscopic incision. When removing the gallbladder, for medium or small gallbladders or gallbladders with few or small stones, first pull the snare line of the cystic duct snare device to arrange the gallbladder longitudinally inside the retrieval bag, then pull the retrieval bag outwards. The medical elastic material skeleton can "compress and shape" the gallbladder, allowing it to be removed completely. For gallbladders with large gallbladders, thickened gallbladders, or large gallstones, a medical elastic material framework can effectively separate the gallbladder or stones from the outer layer of the framework's transparent medical plastic bag. In this case, the medical elastic framework retrieval bag acts like the outer shell of a lantern, with the gallbladder or stones in the center acting as the "lamp inside the lantern." This avoids the "vacuum effect" common with ordinary retrieval bags. Using forceps or other instruments to remove or break up stones in this way will not damage the outer layer of the transparent medical plastic framework, and the "vacuum effect" is eliminated, greatly increasing the efficiency of stone removal, stone fragmentation, and gallbladder extraction. Because the outer layer of the transparent medical plastic framework is not damaged, even if the gallbladder ruptures, it will remain intact within the "lantern," avoiding contact with the abdominal cavity and incision, thus preventing complications.

[0013] The key feature of this invention is the gallbladder duct snare device, which secures and pulls the gallbladder duct, playing a crucial role in gallbladder removal. The medical elastic material skeleton in the gallbladder removal device can perform "forward compression and shaping" of the gallbladder, while avoiding the "vacuum effect" during retrieval. It is easy to operate, simplifies stone fragmentation and removal, improves retrieval efficiency, avoids complications, greatly improves the work efficiency of medical staff, reduces the patient's anesthesia time, reduces surgical trauma, and is more in line with the implementation of minimally invasive surgery.

[0025] Example

[0026] This utility model provides a laparoscopic gallbladder retrieval bag, specifically adopting the following technical solution:

[0027] This utility model discloses a laparoscopic gallbladder retrieval bag, which includes a gallbladder duct loop device 1 and a gallbladder retrieval device 2.

[0028] like Figure 1 As shown, the gallbladder duct snare device consists of an outer tube fixing device 11, a snare line 12, and an inner tube 13.

[0029] The gallbladder removal device comprises an outer tube 21, an inner tube pushing device 22, a medical elastic material skeleton retrieval bag 23, and a closing connecting line 24.

[0030] like Figure 2As shown, the external tube fixation device consists of an external tube fixation device cap 111 and an external tube fixation device body 112, which are connected vertically. The external tube fixation device cap 111 can be fixed to the trocar port of the laparoscopy; the external tube fixation device body 112 provides support and passage for the internal tube and the snare suture.

[0031] like Figure 3 As shown, the snare line 12 is a complete and uninterrupted line, divided into a snare loop 121, a snare knot 122, a middle snare line 123, and a tail loop 124 from one end to the other. The snare knot 122 is a slipknot, allowing for free extension and retraction. The tip 131 of the inner tube presses against the snare knot 122, allowing the snare loop 121 to gradually tighten. The inner tube 13 is open at both ends, with the middle snare line 123 passing through it. The inner tube 13 also provides support for the snare line 12 and provides a direction for the snare knot 122 to contract when the snare loop 121 is contracted. When removing the gallbladder from the abdominal cavity, the snare loop 121 of the gallbladder duct snare device 1 is used to gradually tighten and fix the gallbladder duct, serving as a crucial guide for gallbladder removal.

[0032] like Figure 4-8 As shown, the outer tube 21 of the gallbladder removal device 2 is vertically connected, providing an outer sheath for the medical elastic material skeleton retrieval bag 23 and a channel for the inner tube pushing device 22. The medical elastic material skeleton retrieval bag 23 consists of three medical elastic material skeletons 231, an outer medical transparent plastic bag 233, a fixing plastic sleeve 234, an inner connecting line channel 235, and a closing connecting line 24. The medical elastic material skeleton 231 is flat in the middle, in the shape of a sheet 2311, gradually becoming cylindrical towards both ends 2312, with blunt elliptical ends 2313 to prevent the ends from piercing the outer medical transparent plastic bag 233. The three medical elastic material skeletons 231 are of the same material, length, and shape, with a central connecting hole 232 in the flat middle position. These three holes can be stacked and fixed with rope or small screws. The medical elastic material skeleton 231 can be made of carbon fiber, medical elastic steel wire, medical polymer materials, etc. Three medical elastic material skeletons 231 are fixedly connected through a central connecting hole 232, with each skeleton forming a 60° angle. A fixed plastic sleeve 234 is attached to the outer layer of the skeleton's transparent medical plastic bag 233 to restrict the movement and position of the medical elastic material skeleton 231, allowing it to move vertically but not horizontally. The opening of the outer layer of the skeleton's transparent medical plastic bag 233 is folded back to create a connecting wire channel 235 inside the retrieval bag, allowing the retrieval bag 23 to be closed using a closing connecting wire 24. The connecting wire channel 235 inside the retrieval bag is higher than the head end of the medical elastic material skeleton 231; tightening the opening of the retrieval bag completely covers the head end of the medical elastic material skeleton 231.

[0033] like Figure 4-8As shown, the inner tube pushing device 22 in the gallbladder removal device 2 is a hollow tube closed at one end. The head end 221 of the inner tube pushing device has a pushing plane with a wire hole 222 in the middle, which can form a sufficient contact surface with the medical elastic material skeleton retrieval bag 23. The tail end of the inner tube pushing device 22 is a closed inner tube fixing pull ring 224. There is a tail end wire hole 225 on each of the left and right sides below the inner tube fixing pull ring 224. The closing connection line 24 can be connected to the medical elastic material skeleton retrieval bag 23 through the inner tube fixing pull ring 224, the tail end wire hole 225, the middle part 223 of the inner tube pushing device, and the head end wire hole 222 of the inner tube pushing device. When using the retrieval bag to remove the gallbladder or stones, the outer tube is inserted into the laparoscopic trocar. By pushing the inner tube fixing pull ring 224, the inner tube pushing device 22 pushes the medical elastic material skeleton retrieval bag 23 downward, and finally pushes the medical elastic material skeleton retrieval bag 23 completely into the abdominal cavity. The medical elastic material skeleton retrieval bag 23, once inside the abdominal cavity, will automatically open completely due to the characteristics of its material, allowing stones or gallbladders that have been fixed by the cystic duct loop device 1 to be placed into the medical elastic material skeleton retrieval bag 23.

[0034] like Figure 4-8 As shown, the closing connecting line 24 is a complete line connected end to end. Based on its position, it is artificially divided into an inner connecting line 241 inside the retrieval bag, a connecting line 242 at the body of the inner tube pushing device 22, and a connecting line 243 at the inner tube fixing pull ring. By pulling the connecting line 243 at the inner tube fixing pull ring 224, the connecting line 242 at the body of the inner tube pushing device 22 is driven, causing the inner connecting line 241 inside the retrieval bag to gradually tighten, thus closing the bag and completely enclosing the head end of the medical elastic skeleton 231, allowing it to be removed together with the surgical specimen through the laparoscopic incision.

[0035] It should be noted that this utility model is a laparoscopic gallbladder retrieval bag, and all components are general standard parts. Its structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods.

[0036] Working principle: When removing the gallbladder, for medium and small gallbladders or gallbladders with few or small stones, first pull the loop line 12 of the cystic duct snare device 1 to arrange the gallbladder longitudinally inside the retrieval bag. Then, pull the retrieval bag 23 outward. The medical elastic material skeleton 231 can "compress and shape" the gallbladder, allowing it to be removed completely. For large gallbladders, thickened gallbladders, large stones, or gallstone gallbladders, the medical elastic material skeleton 231 can fully separate the gallbladder or stone from the outer medical transparent plastic bag 233. At this time, the medical elastic skeleton retrieval bag 23 is like the outer shell of a "lantern," and the gallbladder or stone in the center is like the "lamp inside the lantern," avoiding the "vacuum effect" when retrieving items with ordinary retrieval bags. At this time, the use of forceps and other instruments to remove or break stones will not damage the outer medical transparent plastic 233 of the skeleton, and the influence of the "vacuum effect" is eliminated, greatly increasing the efficiency of stone removal, stone breaking, and gallbladder removal. Because the outer layer of the medical-grade transparent plastic frame is not damaged, even if the gallbladder ruptures, it will remain intact within the "lantern," avoiding contact with the abdominal cavity and incision. This prevents complications such as abdominal infection, poor wound healing, and tumor dissemination. Consequently, the procedures for lithotripsy, stone removal, and object retrieval are simplified, improving efficiency and significantly increasing the work efficiency of medical staff. Simultaneously, it reduces the patient's anesthesia time, minimizes surgical trauma, and better aligns with minimally invasive surgery.
