Problems solved by technology

[0003] Existing devices for taking out stones in hepatobiliary surgery basically take out the stones in the patient's body in the form of tweezers, and taking out the stones in this way not only can only take out one stone at a time, but also it is difficult to accurately remove the small stones. Clamping, not only the removal efficiency is low, but also when the stone removal device is sent into the body, because the intestinal tract is not straight, it is relatively slow to be sent into the intestinal tract

Embodiment 1

[0032] combine figure 1 and figure 2 , a device for eliminating liver and gallstones, comprising a cylinder 1, the right end of the cylinder 1 is fixedly connected with a mounting plate 2, the inside of the cylinder 1 is provided with a partition 6, and the inside of the cylinder 1 runs through the partition The plate 6 is provided with a stone extraction cylinder 10 and a cleaning cylinder 11, and the stone extraction cylinder 10 is provided with a suction tube 8, one end of the suction tube 8 is set through the mounting plate 2, and the other end of the suction tube 8 passes through the left end of the cylinder body 1 The first through groove 14 of the cleaning cylinder 11 is provided with a needle tube 9, one end of the needle tube 9 is set through the mounting plate 2, and the other end of the needle tube 9 passes through the second through groove 16 at the left end of the cylinder body 1, One end of the suction pipe 8 close to the first through groove 14 is connected to...

Embodiment 2

[0037] combine figure 1 and image 3 , After the stone extraction is completed, the mesh basket shrinks into the stone extraction cylinder through the suction tube, pushes the needle tube to the left, and the needle compression spring protrudes through the third channel, which is convenient for injecting medicine and controlling the water intake. Repeatedly fill water several times with intervals of several minutes. After choledochoscopy checks for no stones, deflate the balloon through a syringe, withdraw the whole device from the gallbladder and common bile duct, and pull the absorption tube to the right to take out the stones and return them to the cylinder. The needle tube protrudes from the second through groove, which is convenient for drug injection. It has complete functions and a wide field of view. The suction tube, drainage tube and needle tube are worn in the cylinder at the same time. The structure is simple and easy to use, and it is convenient to take out larger...

Embodiment 3

[0039]On the basis of Example 1, the balloon adopts silicone rubber, the addition of the base rubber in the silicone rubber is 20-40%, the addition of white carbon black is 8-10%, and the tearing of the silicone rubber The crack strength is 3.52-3.58KN / m, the tensile strength is 2.66-2.87MPa, and the elongation at break is 336-339%.

[0040] Silicone rubber can be in full contact with the bile duct, and its elasticity and tensile strength meet the requirements of angles and bending degrees at different bile ducts. Silicone rubber can make various deformations accordingly. Excellent mechanical properties, so that the hardness can meet the needs of use and avoid collapse.

[0041] The cylinder adopts magnesium alloy, and the composition and content of the magnesium alloy are: 3.5-4.3% of yttrium, 1.8-2.5% of neodymium, 0.3-0.7% of lanthanum, 0.5-0.6% of cerium, 0.03-0.08% of titanium, 0.4% of zirconium -0.6%, the rest is magnesium, preferably, the composition of the magnesium a...

Abstract

The invention relates to a removing device for hepatolithiasis. The removing device comprises a barrel, wherein the right end of the barrel is fixedly connected with a mounting plate, a partition plate is arranged in the barrel, a balloon is arranged outside the barrel, a stone taking barrel and a cleaning barrel are arranged in the barrel and penetrate through the partition plate, a suction tubeis arranged in the stone taking barrel, one end of the suction tube penetrates through the mounting plate, the other end of the suction tube penetrates through a first through groove in the left end of the barrel, a syringe is arranged in the cleaning barrel, one end of the syringe penetrates through the mounting plate, and the other end of the syringe penetrates through a second through groove inthe left end of the barrel. The removing device realizes coating of large stone and excision and clamping of small residual stone, facilitates medicine injection, and has complete functions and widefield of view.

Description

technical field [0001] The invention belongs to the technical field of hepatobiliary surgery, and in particular relates to a device for eliminating hepatobiliary stones. Background technique [0002] Biliary stones are a common disease in surgery. Stones in the common bile duct can cause biliary obstruction secondary to jaundice, cholangitis, and even pancreatitis, which is life-threatening. Surgery is the only way to treat the disease. Choledochoscopic stone removal is a method commonly used in surgery for the treatment of biliary calculi at present. During this process, a fiberoptic choledochoscope is usually placed along the incision of the biliary tract. After the stone is found, the stone is removed with a stone removal mesh. [0003] Existing devices for taking out stones in hepatobiliary surgery basically take out the stones in the patient's body in the form of tweezers, and taking out the stones in this way not only can only take out one stone at a time, but also it...
