Description

Technical Field

[0001] The utility model relates to the field of medical supplies, in particular to a hemostatic device for post-operative removal of intrahepatic bile duct stones. Background Art

[0002] Intrahepatic bile duct stone removal is a surgical procedure used to treat hepatobiliary stones. The procedure generally involves: after the patient is given general anesthesia, a needle is inserted into the left or right hepatic duct under ultrasound guidance. A guidewire is then passed through the needle and guided to the lesion. A dilating sheath is used to dilate the skin and the ducts in the liver and gallbladder. Once the bile duct is fully dilated, lithotripsy and stone removal are performed with the assistance of a choledochoscope. Finally, a drainage tube is placed at the puncture site to drain the bile.

[0003] After stone removal, the incision on the internal organs needs to be hemostatically controlled. This is achieved by creating a hemostatic block with hemostatic material and inserting it into the surgical incision. Currently, the applicant uses a mixture of absorbable hemostatic powder, hemostatic filaments, and a small amount of water to create a flexible, plasticine-like hemostatic block. This block is then molded into a cylindrical shape and inserted into the surgical incision to stop bleeding. To facilitate the insertion of the hemostatic block into the surgical incision, a suitable auxiliary tool is ideal.

[0004] After searching, the patent application number 202122033803.5 discloses a hemostatic device for laparoscopic surgery in the hepatobiliary department, including a dowel seat, a main rod fixedly mounted on the front of the dowel seat, a push rod movably mounted inside the main rod, the outer diameter of the push rod being equal to the inner diameter of the main rod, and a handle fixedly mounted on the back of the dowel seat. The patent includes a dowel seat, a main rod, a driving mechanism, a hemostatic mechanism 1, and a hemostatic mechanism 2. The hemostatic mechanism 1 is connected to the main rod by a thread, which is convenient for disassembly and assembly, and a packing block with a hemostatic bag is filled into the cannula. The cannula is inserted into the blood vessel by driving the push rod through the handle, and then the packing block and the hemostatic bag are pushed into the blood vessel through the center rod to pack and stop bleeding.

[0005] The hemostatic device of the above patent can assist in the operation of packing hemostatic blocks, such as hemostasis of surgical incisions, but its structure is relatively complex, not suitable for single-use, and is inconvenient to clean and disinfect after surgery. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 and Figure 2 As shown, the hemostatic device for postoperative intrahepatic bile duct stone removal includes a drug guide tube 1, an annular airbag 5, a push rod 2, an inflatable structure 3 and a hemostatic drug block 6; an airbag groove 11 is provided on the inner wall of the front end of the drug guide tube 1, and the drug guide tube 1 has an air guide hole 12 extending from the rear end of the drug guide tube 1 to the airbag groove 11; the annular airbag 5 is located in the airbag groove 11, the annular airbag 5 is connected to the drug guide tube 1 and communicates with the air guide hole 12; the inflatable structure 3 is located at the rear end of the drug guide tube 1, the inflatable structure 3 is connected to the drug guide tube 1 and communicates with the air guide hole 12; the push rod 2 is inserted into the drug guide tube 1; the hemostatic drug block 6 can be placed in the drug guide tube 1, and the inflation of the annular airbag 5 can limit the forward movement of the hemostatic drug block 6 placed in the drug guide tube 1.

[0025] When the utility model is used, Figure 2 As shown, put the hemostatic block 6 into the drug guide tube 1; then Figure 3As shown, the annular airbag 5 is inflated using the inflatable structure 3, and the annular airbag 5 expands and blocks the front of the hemostatic block 6 to prevent the hemostatic block 6 from slipping out. The drug guide tube 1 is then inserted through the abdominal surgical incision and extended to the surgical incision of the internal organs. The annular airbag 5 is then deflated to release its obstruction to the hemostatic block 6. The push rod 2 is then pushed forward, and the push rod 2 pushes the hemostatic block 6 into the surgical incision. The hemostat is then withdrawn from the human body, completing the hemostatic operation. This shows that the present invention can achieve hemostasis after intrahepatic bile duct stone removal surgery.

[0026] The drug guide tube 1 is made of a flexible plastic tube, and the push rod 2 is preferably a flexible plastic rod; although the drug guide tube 1 and the push rod 2 are flexible, they should not be too soft, and their bending characteristics can be the same as those of a common fluorescent stick. Preferably, the front end of the push rod 2 cooperates with the drug guide tube 1, and the front end surface of the push rod 2 is a plane. The airbag is a common component on medical tubes, and is found on urinary catheters and gastric tubes. The material of the annular airbag 5 is the same as that of the airbags on existing medical tubes. When the annular airbag 5 is not inflated, it is stored in the airbag groove 11 and does not block the hemostatic block 6. The hemostatic block 6 can be made using existing methods. For example, the hemostatic block 6 is made by mixing hemostatic powder, hemostatic fibrils and water, and the shape of the hemostatic block 6 is cylindrical.

[0027] The specific structure of the inflatable structure 3 can be as follows Figure 4 As shown, the inflatable structure 3 includes an inflation tube 32, a tube clamp 33, and an inflation connector 31. The inflation tube 32 is connected to the drug guide tube 1, and the tube clamp 33 is disposed on the inflation tube 32. The inflation connector 31 is connected to the inflation tube 32. The inflation connector 31 is used to connect other inflatable items, such as a syringe. By connecting an existing syringe to the inflation connector, the syringe can fill air into the annular airbag 5 through the inflation tube 32 and the air guide hole 12. After inflation, the tube clamp 33 is closed to prevent the gas in the annular airbag 5 from leaking out. The tube clamp 33 can be a tube clamp commonly used in medical pipelines. If it is necessary to remove the obstruction of the hemostatic drug block 6, the tube clamp 33 is opened to release the gas in the annular airbag 5; alternatively, the air can be pumped out with a syringe to ensure that the gas in the annular airbag 5 is completely released.

[0028] The inflatable structure 3 can also be inflated by itself, so that it does not need to be inflated with the help of other objects, which is more convenient. Figure 5 As shown, the inflation structure 3 includes an inflation tube 32, a tube clamp 33, and an inflation balloon 34. The inflation tube 32 is connected to the drug guiding tube 1, and the tube clamp 33 is set on the inflation tube 32. The inflation balloon 34 is connected to the inflation tube 32. The inflation balloon 34 can be inflated by squeezing it; when the inflation balloon 34 is released, the inflation balloon 34 rebounds by its own elasticity and absorbs the gas in the annular airbag 5 back.

[0029] The hemostatic block 6 can be prepared by medical personnel during surgery using the method described in the technical description, but this is time-consuming. Preferably, the hemostatic block 6 is prefabricated and can be used directly during surgery. A specific configuration is as follows: The hemostatic device for post-operative hepatobiliary stone removal includes a medicine box 4 and a sealed packaging bag 7. The medicine box 4 is connected to the rear end of the push rod 2. The sealed packaging bag 7 contains the hemostatic block 6 and is placed within the medicine box 4.

[0030] The prefabricated hemostatic medicine block 6 is still made by prior art. The sealed packaging bag 7 is packaged to prevent it from deteriorating. During the operation, the hemostatic medicine block 6 is taken out and then put into the drug guiding tube 1 and use.
