Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a postoperative negative pressure drainage device for pancreatic surgery. Background Technology

[0002] In the field of pancreatic surgery, postoperative pancreatic fistula (POPF) is one of the most common and serious complications after pancreatic surgery. Despite significant advancements in surgical techniques and medical care over the past decade, the incidence of POPF remains as high as 30%–45% in major central hospitals. POPF not only prolongs hospital stays but also increases the risk of postoperative complications such as infection and bleeding, severely impacting patient prognosis.

[0003] The main cause of postoperative pancreatic fistula is leakage of pancreatic juice after pancreatic surgery, which leads to the accumulation of a large amount of pancreatic juice in the abdominal cavity. If the drainage is insufficient, the pancreatic juice will accumulate in the abdominal cavity, further causing serious complications such as abdominal infection and bleeding. At present, the drainage tube is used to drain pancreatic juice during surgery, but this method has technical problems: the low drainage efficiency leads to the accumulation of pancreatic juice in the abdominal cavity. Utility Model Content

[0004] Based on the above analysis, the present invention aims to provide a postoperative negative pressure drainage device for pancreatic surgery to solve the technical problem of pancreatic fluid accumulation in the abdominal cavity due to low drainage efficiency of existing drainage methods.

[0005] The objective of this utility model is mainly achieved through the following technical solutions: A postoperative negative pressure drainage device for pancreatic surgery includes a pancreatic juice absorption block, a drainage tube, and a negative pressure drainer. The pancreatic juice absorption block is disposed in the abdominal cavity, and the drainage tube connects the pancreatic juice absorption block and the negative pressure drainer. The pancreatic fluid absorption block includes an absorption block body and a pancreatic fluid collection cavity. The absorption block body is disposed in the abdominal cavity to absorb pancreatic fluid produced by pancreatic leakage after pancreatic surgery. The pancreatic fluid collection cavity is opened on the absorption block body to collect the pancreatic fluid, and the pancreatic fluid collection cavity is connected to the drainage tube to drain the pancreatic fluid to the negative pressure drainage device.

[0006] Furthermore, the pancreatic juice absorption block also includes a pancreatic juice flow cavity, which extends between the absorption block body and the pancreatic juice collection cavity to allow the pancreatic juice to flow into the pancreatic juice collection cavity.

[0007] Furthermore, the absorbent block body includes a first absorbent block and a second absorbent block. The first absorbent block is in contact with the pancreas to absorb pancreatic fluid produced by pancreatic leakage after pancreatic surgery. The second absorbent block is fixedly disposed on the first absorbent block, and the drainage tube is connected to the second absorbent block.

[0008] Furthermore, the postoperative negative pressure drainage device for pancreatic surgery also includes an irrigation tube, which includes an injection tube, a delivery tube, and an outlet tube connected in sequence. The injection tube passes through the drainage tube to inject irrigation fluid into the delivery tube. The delivery tube is disposed in the drainage tube to deliver irrigation fluid. The outlet tube is connected to the pancreatic juice collection cavity to dilute the accumulated fluid in the pancreatic juice collection cavity.

[0009] Furthermore, the postoperative negative pressure drainage device for pancreatic surgery also includes a collection tube, which includes a collection tube body and a collection hole formed on the collection tube body. The collection tube body is disposed in the pancreatic juice collection cavity to collect pancreatic juice, and the collection tube body is connected to the drainage tube to allow pancreatic juice to flow into the drainage tube.

[0010] The technical solution of this utility model can achieve at least one of the following effects: (1) The postoperative negative pressure drainage device for pancreatic surgery described in this utility model includes a pancreatic juice absorption block, a drainage tube, and a negative pressure drainer; the pancreatic juice absorption block includes an absorption block body and a pancreatic juice concentration chamber. The absorption block body is placed in the abdominal cavity to absorb pancreatic juice produced by pancreatic leakage after pancreatic surgery.

Detailed Implementation

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0016] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0017] Example 1 like Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides a postoperative negative pressure drainage device for pancreatic surgery, including a pancreatic juice absorption block 1, a drainage tube 2, and a negative pressure drainer 3. The pancreatic juice absorption block 1 is placed in the abdominal cavity, the drainage tube 2 is connected to the pancreatic juice absorption block 1, and the negative pressure drainer 3 is connected to the drainage tube. The pancreatic juice absorption block 1 includes an absorption block body 11 and a pancreatic juice collection chamber 12. The absorption block body 11 is placed in the abdominal cavity to absorb pancreatic juice produced by pancreatic leakage after pancreatic surgery. The pancreatic juice collection chamber 12 is opened on the absorption block body 11 to collect pancreatic juice, and the pancreatic juice collection chamber 12 is connected to the drainage tube 2 to release pancreatic juice to the negative pressure drainer 3.

[0018] The pancreatic juice absorption block 1 is placed in the abdominal cavity and comes into direct contact with the pancreas. It is used to absorb pancreatic juice produced by postoperative pancreatic leakage. For example, the pancreatic juice absorption block 1 is made of absorbable sponge material that can be absorbed by the human body. Its appearance is disc-shaped, but it is not limited to this. The pancreatic juice absorption block 1 has a pit on it so that pancreatic juice can be collected.

[0019] The drainage tube 2 is connected between the pancreatic juice absorption block 1 and the negative pressure drainage device 3, and plays the role of transporting pancreatic juice, ensuring that the pancreatic juice can flow from the pancreatic juice absorption block 1 to the negative pressure drainage device 3, and that the pancreatic juice can be transferred out of the body to avoid the accumulation of pancreatic juice in the body and causing infection. For example, the drainage tube 2 can be made of silicone or polyurethane.

[0020] The pancreatic juice absorption block 1 includes an absorption block body 11 and a pancreatic juice concentration cavity 12. The absorption block body 11 is in direct contact with the pancreatic juice in the abdominal cavity and can absorb the pancreatic juice produced by pancreatic leakage after pancreatic surgery. It is made of absorbable sponge material, which can quickly absorb pancreatic juice. The pancreatic juice concentration cavity 12 is a through cavity opened in the absorption block body 11 to collect the absorbed pancreatic juice. The pancreatic juice concentration cavity 12 concentrates the dispersed pancreatic juice, which is convenient for subsequent drainage. Through the absorption block body 11 and the pancreatic juice concentration cavity 12, the exudate postoperative pancreatic juice is absorbed in the absorption block body 11, preventing the pancreatic juice from accumulating in the abdominal cavity. At the same time, it also increases the drainage area, reduces the risk of infection, and promotes wound healing, solving the technical problem of pancreatic juice accumulation in the abdominal cavity due to low drainage efficiency of existing drainage methods.

[0021] A preferred embodiment of this utility model is as follows: Figure 2 and Figure 3 As shown, the pancreatic juice absorption block 1 also includes multiple pancreatic juice flow chambers 13, which are connected between the absorption block body 11 and the pancreatic juice concentration chamber 12 so that pancreatic juice flows into the pancreatic juice concentration chamber 12.

[0022] The pancreatic juice flow chamber 13 forms multiple pancreatic juice flow paths, collecting pancreatic juice at multiple locations and converging it into the pancreatic juice concentration chamber 12. The pancreatic juice flow chamber 13 provides a flow path for pancreatic juice, allowing it to flow quickly from the absorbent block body 11 to the pancreatic juice concentration chamber 12, and then be discharged from the body through the drainage tube 2. This reduces the residence time of pancreatic juice in the abdominal cavity, thereby reducing the stimulation and potential damage of pancreatic juice to the abdominal tissues.

[0023] A preferred embodiment of this utility model is as follows: Figure 2 and Figure 3As shown, the absorbent block body 11 includes a first absorbent block 111 and a second absorbent block 112. The first absorbent block 111 is in contact with the pancreas to absorb pancreatic fluid produced by pancreatic leakage after pancreatic surgery. The second absorbent block 112 is fixedly disposed on the first absorbent block 111. The drainage tube 2 is connected to the second absorbent block 112. The second absorbent block 112 has a higher hardness than the first absorbent block 111 to support the first absorbent block 111.

[0024] The first absorbent block 111 is in direct contact with the pancreas and is used to directly absorb pancreatic fluid produced by pancreatic leakage after pancreatic surgery. The first absorbent block 111 also protects the pancreatic tissue. Due to its softness, the first absorbent block 111 can reduce mechanical damage to the pancreatic tissue and avoid tissue compression or damage that may be caused by direct contact of hard materials with the pancreas. The second absorbent block 112 is harder than the first absorbent block 111 and is mainly used to support the first absorbent block 111 to ensure its stability in the abdominal cavity. This prevents the first absorbent block 111 from becoming too soft and deforming or shifting after absorbing pancreatic fluid. The second absorbent block 112 is fixedly mounted on the first absorbent block 111 and connected to the drainage tube 2, which guides the absorbed pancreatic fluid to the drainage tube. Due to its higher hardness, the second absorbent block 112 can protect the interface of the drainage tube 2 and prevent damage or detachment of the interface due to friction or compression of intra-abdominal tissues.

[0025] Example 2 Based on Example 1, such as Figure 4 As shown, the postoperative negative pressure drainage device for pancreatic surgery also includes an irrigation tube 4. The irrigation tube 4 includes an injection tube 41, a delivery tube 42, and an outlet tube 43 connected in sequence. The injection tube 41 passes through the drainage tube 2 to inject the irrigation fluid into the delivery tube 42. The delivery tube 42 is located in the drainage tube 2 to deliver the irrigation fluid. The outlet tube 43 is connected to the pancreatic juice collection chamber 12 to dilute the accumulated fluid in the pancreatic juice absorption block 1. In specific applications, the injection tube 41 is connected to the infusion device to inject the irrigation fluid into the injection tube 41. For example, the irrigation fluid is physiological saline. The irrigation fluid is delivered to the pancreatic juice collection chamber 12 through the delivery tube 42 and the outlet tube 43 to dilute the accumulated fluid. By diluting the pancreatic juice, the viscosity of the pancreatic juice can be reduced, preventing it from condensing in the pancreatic juice collection chamber 12 and the drainage tube 2, avoiding blockage, and ensuring smooth drainage.

[0026] Example 3 Based on Example 1, Example 2 or Example 3, such as Figure 5As shown, the postoperative negative pressure drainage device for pancreatic surgery also includes a collection tube 5. The collection tube 5 includes a collection tube body 51 and collection holes 52 opened on the collection tube body 51. The collection tube body 51 is disposed in the pancreatic juice collection cavity 12 to collect pancreatic juice, and the collection tube body 51 is connected to the drainage tube 2 to allow pancreatic juice to flow into the drainage tube 2. Multiple collection holes 52 are provided. The collection holes 52 increase the collection area of ​​pancreatic juice, improve the collection efficiency, and reduce the accumulation of pancreatic juice in the pancreatic juice collection cavity 12. For example, the collection tube 5 can be made of rubber.

[0027] Based on this, since the liquid collecting tube 5 has a certain length, such as Figure 4 and Figure 5 As shown, the pancreatic juice absorption block 1 can be a sheet-like structure, such as a rectangular sheet-like structure, and the pancreatic juice absorption block 1 can be cut. The pancreatic juice absorption block 1 is made of absorbable sponge material. The sheet-like structure of the pancreatic juice absorption block 1 can better conform to the shape of the pancreas in the abdominal cavity, ensuring that the absorption block is in close contact with the surface of the pancreas and improving absorption efficiency. In clinical practice, medical staff can adjust its size and shape according to actual needs to adapt to the specific conditions and surgical requirements of different patients.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
