Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an abdominal water leakage prevention device for percutaneous transhepatic and transbiliary lithotripsy. Background Art
[0002] Biliary stones are a common disease in my country, especially in coastal areas. They can occur in the common bile duct, gallbladder and common hepatic duct, as well as in the confluence of the left and right hepatic ducts and the intrahepatic bile duct system. They can be diffuse and multiple, or localized in the bile ducts of a certain liver segment or lobe. Because the intrahepatic bile duct has many branches and the anatomical structure may vary, patients with a history of multiple biliary surgeries are prone to abdominal adhesions, the liver is deformed by traction, and inflammatory atrophy. In addition, the location, number, and size of bile duct stones vary, so the treatment of complex bile duct stones is particularly difficult. How to improve the stone removal rate and treat it as minimally invasively as possible is the difficulty in treating this disease.
[0003] PTCS percutaneous transhepatic choledocholithotomy is a minimally innovative technology in the field of hepatobiliary stones. This technology combines and improves percutaneous transhepatic bile drainage and percutaneous transhepatic choledochoscopy. It enters the intrahepatic bile duct through skin and liver puncture, and after multiple expansions to a predetermined thickness, a support sheath is inserted, which is like a bridge between the intrahepatic bile duct and the outside world. The percutaneous nephroscope can repeatedly enter and exit the intrahepatic bile duct through this "bridge". The intrahepatic stones and diseased bile duct can be seen on the display screen. Smaller stones are directly removed with stone forceps or stone baskets, and larger stones are crushed with equipment such as pneumatic ballistic lithotripsy and discharged with water through the support sheath or bile-enteric anastomosis. The entire surgical process is performed under ultrasound guidance or C-arm angiography, which is safe and reliable. Since the choledochoscope enters the bile duct and intrahepatic bile duct, in order to fill the bile duct cavity and keep the endoscopic field clear, it is necessary to continuously drip normal saline through the side hole of the choledochoscope for flushing. However, the operation usually takes 0.5-2 hours, during which the liquid flushed into the bile duct constantly overflows from the fistula, not only contaminating the operation field and the operating table, but also soaking the patient's clothes and the operator's clothes. For a long time, surgical adhesive films have been used to stick the operation field, or disposable drainage bags have been temporarily converted into water collection bags and pasted under the fistula, but the operation field, the operator and the patient are still easily soaked and contaminated by the liquid, affecting the smooth progress of the operation. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide an abdominal water leakage prevention device for percutaneous transhepatic choledocholithotomy, which can collect and store the flushing liquid overflowing from the fistula of the patient during the operation, and effectively prevent the surgical field, the operator and the patient from being soaked and contaminated by the liquid, thereby ensuring the smooth progress of the operation. The technical solution adopted is as follows:
[0005] An abdominal water leakage prevention device for percutaneous transhepatic choledocholithotomy, comprising an abdominal wall-fitting waterproof membrane, an adhesive layer being provided on the bottom surface of the abdominal wall-fitting waterproof membrane, and at least one surgical window being provided on the middle surface of the abdominal wall-fitting waterproof membrane, characterized in that: the front and rear side edges of the abdominal wall-fitting waterproof membrane are provided with upwardly extending water-retaining membrane walls, and the abdominal wall-fitting waterproof membrane and its two water-retaining membrane walls together form a left-right liquid conduction groove; the abdominal water leakage prevention device also includes a negative pressure drainage bottle, a three-way joint and two collecting pipes, the upper ends of the two collecting pipes are respectively connected to the left and right ends of the liquid conduction groove; the first interface and the second interface of the three-way joint are respectively connected to the lower ends of the two collecting pipes, and the drainage pipe of the negative pressure drainage bottle is connected to the third interface of the three-way joint.
[0006] Before percutaneous transhepatic choledochoscope lithotripsy, the abdominal wall-fitting waterproof membrane of the above-mentioned abdominal water-proof device can be attached to the corresponding position of the patient's abdominal wall through the adhesive layer, and the left and right ends of the abdominal wall-fitting waterproof membrane are naturally drooped along the left and right sides of the patient's abdominal wall, and connected to the negative pressure drainage bottle through two collecting tubes and three-way joints (the negative pressure drainage bottle can be placed on the ground and directly below the center of the operating table). When normal saline is continuously dripped through the side hole of the choledochoscope for flushing during the operation, the liquid flushed into the bile duct continuously overflows from the fistula of the patient's abdomen to the smooth upper surface of the abdominal wall-fitting waterproof membrane, and flows into the two collecting tubes along the liquid guide groove to the left and right sides. The two water-retaining membrane walls can prevent the liquid in the liquid guide groove from flowing out from the front and back sides of the abdominal wall-fitting waterproof membrane, thereby effectively preventing contamination of the surgical field, the operator and the patient, thereby ensuring the smooth progress of the operation; finally, the liquid in the two collecting tubes flows into the negative pressure drainage bottle through the three-way joint and the drainage tube under the negative pressure generated by the negative pressure drainage bottle for storage. This abdominal water leakage prevention device can collect the flushing liquid overflowing from the fistula of the patient's abdomen through the waterproof film during the operation, and smoothly guide the flushing liquid into the negative pressure drainage bottle for storage using two collecting pipes and three-way joints, which can effectively reduce the workload of medical staff and effectively prevent the surgical field, the operator and the patient from being soaked and contaminated by the liquid, thereby ensuring the smooth progress of the operation. In addition, during the operation, the negative pressure drainage bottle can be placed on the ground and directly below the center of the operating table, which can reduce the pulling force exerted by the negative pressure drainage bottle on the patient's abdomen and prevent it from being accidentally touched by the footsteps of medical staff and tipped over, making it safer to use.
[0007] The abdominal wall-adhering waterproof membrane may be a conventional surgical adhesive film or other sterile waterproof membranes.
[0008] As a preferred solution of the utility model, the abdominal wall-fitting waterproof membrane has a smooth upper surface.
[0009] As a preferred solution of the utility model, the upper part of the water retaining membrane wall is provided with a folded edge part. By providing the folded edge parts on the upper parts of the two water retaining membrane walls, it is easy to stand up the two water retaining membrane walls.
[0010] As a further preferred embodiment of the present invention, a plastic positioning strip extending in the left-right direction is provided in the folded edge. Specifically, the plastic positioning strip can be a thin plastic strip. This makes it easier to stand up the two water-retaining membrane walls, and the position of the water-retaining membrane walls can be adjusted by bending and shaping the plastic positioning strip.
[0011] As a preferred solution of the utility model, the cross-sectional area of the inner cavity of the manifold gradually decreases from its upper end to its lower end. Thus, the manifold is more likely to smoothly guide the liquid flowing out of one end of the liquid guide groove into the negative pressure drainage bottle through the three-way joint and the drainage tube.
[0012] As a preferred solution of the present utility model, the adhesive layer is made of biological glue.
[0013] As a preferred solution of the utility model, the number of the surgical windows is multiple; the surgical window includes an opening opened on the middle surface of the abdominal wall-fitting waterproof membrane, and a movable shielding sheet for closing the opening and being torn from one side thereof. Specifically, the multiple surgical windows are distributed on multiple parts of the patient's abdomen that require surgical operations. During the operation, the doctor can tear off the movable shielding sheet of the surgical window at the corresponding part as needed, so that the medical staff can perform interventional puncture and other surgical operations during the operation.

[0015] Compared with the prior art, the utility model has the following advantages:
[0016] (1) During surgery, this abdominal water leakage prevention device can collect the flushing fluid overflowing from the fistula of the patient's abdomen through a fitted waterproof film, and use two collecting pipes and a three-way joint to smoothly guide the flushing fluid into the negative pressure drainage bottle for storage, which can effectively reduce the workload of medical staff; and when used during surgery, the negative pressure drainage bottle can be placed on the ground and directly below the center of the operating table, which can reduce the pulling force exerted by the negative pressure drainage bottle on the patient's abdomen and prevent it from being accidentally touched by the footsteps of medical staff and tipped over, making it safer to use.
