Abstract
Description
Technical Field
[0001] This utility model relates to the field of stone removal device technology, and in particular to a stone removal device for the treatment of biliary stones. Background Technology
[0002] Gallstones are a common disease in hepatobiliary surgery. Traditional treatments for gallstones mainly include medication and surgery. Surgical treatment usually involves open surgery or laparoscopic surgery. Open surgery is more invasive, has a longer recovery time, and is prone to complications. Although laparoscopic surgery is relatively less invasive, it also has certain limitations, such as the greater difficulty in handling complex gallstone cases. To facilitate the smooth removal of gallstones during laparoscopic surgery, some new stone removal devices have emerged on the market to assist surgeons in efficiently removing gallstones.
[0003] Currently, most stone removal methods rely on negative pressure absorption, which is typically achieved through pipes connected to the negative pressure device. However, the current pipe structure is simple and makes it difficult to store the stones after absorption, resulting in a high probability of backflow. Ensuring sufficient negative pressure and rapid removal of the stone removal device requires a high level of operational skill and has room for improvement. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stone removal device for the treatment of biliary stones.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A stone removal device for treating biliary stones includes a pipe, a T-junction pipe fixedly connected to the air inlet of the pipe, and a stone filter screen installed at the air inlet of the pipe. A connector is fixedly located on the pipe away from the air inlet, and the connector is fixedly fitted with a pagoda connector. A material guide channel is fixedly connected to the bottom of the pipe and is configured to communicate with the pipe. An installation channel is fixedly connected to the top of the pipe. A baffle is installed inside the pipe on the material guide channel. A pressing mechanism for moving the baffle is installed on the outer wall of the pipe.
[0006] In this embodiment, upper baffles are fixed on both sides of the top of the outer wall of the baffle.
[0007] In this embodiment, two symmetrically arranged side baffles are fixed on both sides of the outer wall of the baffle, and the upper baffle and the side baffles are both arranged in close contact with the inner wall of the material guide channel.
[0008] In this embodiment, the pressing mechanism includes a screw, the bottom of which is fixed to the outer wall of the baffle. An installation collar is fixedly sleeved on the outer wall of the pipe. A pressure plate is rotatably connected to the installation collar via a shaft. A slot is opened at the top of the pressure plate. The screw passes through the slot. A fixing sleeve located below the pressure plate is fixedly sleeved on the outer wall of the screw. A spring is provided at the bottom of the fixing sleeve and is sleeved on the outer wall of the screw.
[0009] In this embodiment, a sealing sleeve is fixed to the inner wall of the installation channel, a sealing ring is fixed inside the sealing sleeve, and the pressing mechanism is disposed through the sealing ring.
[0010] In this embodiment, the outer wall of the screw is threaded with a threaded sleeve, and the threaded sleeve is located on the top of the pressure plate.
[0011] In this embodiment, the outer wall surface of the pressure plate is provided with anti-slip texture to prevent slipping.
[0012] In this embodiment, a collection box is installed in the material guiding channel, and slag discharge ports are provided on both sides of the outer wall of the collection box.
[0013] In this embodiment, a square closing frame is fixed to the bottom of the inner wall of the collection box. The square closing frame has a closing function to prevent it from being sucked back.
[0014] In this embodiment, the outer wall of the collection box and the outer wall of the material guiding channel are provided with interconnected holes. Magnets are fixed in the holes, and the magnets located on the collection box and the material guiding channel attract each other. A collection box is provided in the material guiding channel. The collection box is magnetically attached to the material guiding channel, which facilitates the disassembly of the collection box and the emptying of the stones collected in the collection box, allowing them to be discharged from the slag discharge port.
[0015] In this embodiment, a filter screen mounting bracket is fixed to the inner wall end of the pipe away from the pagoda joint, and the stone filter screen is fixed on the filter screen mounting bracket.
[0016] The beneficial effects of this utility model are as follows: This utility model, by incorporating a pipe, a tee connector, a joint, a pressing mechanism, and a baffle, allows the screw to move downwards. As the baffle, which originally blocked half the inner diameter of the pipe, moves downwards, upper baffles are fixed on both sides of the baffle, effectively blocking the material guide channel. When stones enter the pipe, the stone filter screen intercepts them. Then, the negative pressure device is closed, maintaining the pipe's inclination. Simultaneously, the pressure on the pressure plate is quickly released, causing the retaining sleeve to spring upwards, which in turn moves the screw upwards. This causes the baffle, located within the material guide channel, to move upwards, blocking half of the pipe and preventing stones from sliding out of the pagoda joint. This effectively solves the problems raised in the background technology, enabling the interception and collection of stones after absorption, preventing backflow of stones from the pagoda joint, and facilitating operation.
[0017] This utility model features a collection box that is magnetically attached to the material guide channel, facilitating its disassembly and allowing the stones collected inside the collection box to be poured out through the slag discharge port.
[0018] This utility model: A square closing frame is fixed to the bottom of the inner wall of the collection box, and the square closing frame has a closing function to prevent it from being sucked back. Attached Figure Description

A fixing sleeve 705 located below the pressure plate 702 is fixedly sleeved on the outer wall of the screw 704. A spring 703 is provided at the bottom of the fixing sleeve 705. The spring 703 is sleeved on the outer wall of the screw 704.
[0027] In this embodiment, a sealing sleeve 9 is fixed to the inner wall of the installation channel 8, and a sealing ring is fixed inside the sealing sleeve 9. The pressing mechanism 7 is set through the sealing ring.
[0028] In this embodiment, the outer wall of the screw 704 is threadedly connected to a threaded sleeve 706, and the threaded sleeve 706 is located on the top of the pressure plate 702.
[0029] In this embodiment, the outer surface of the pressure plate 702 is provided with anti-slip texture to prevent slipping.
[0030] In this embodiment, a collection box 5 is installed in the material guiding channel 4, and slag discharge ports 15 are opened on both sides of the outer wall of the collection box 5.
[0031] In this embodiment, a square closing frame 14 is fixed to the bottom of the inner wall of the collection box 5. The square closing frame 14 has a closing function to prevent it from being sucked back.
[0032] In this embodiment, the outer wall of the collection box 5 and the outer wall of the material guiding channel 4 are provided with interconnected holes. A magnet 6 is fixed in the hole. The magnets 6 on the collection box 5 and the material guiding channel 4 attract each other. The collection box 5 is provided in the material guiding channel 4. The collection box 5 is magnetically attracted to the material guiding channel 4, which facilitates the disassembly of the collection box 5 and the pouring out of the stones collected in the collection box 5 so that they can be discharged from the slag discharge port 15.
[0033] In this embodiment, a filter mounting bracket 17 is fixed to the inner wall end of the pipe 1 away from the pagoda connector 16, and the stone filter 18 is fixed on the filter mounting bracket 17.
[0034] Working principle: The device includes a pipe 1, a three-way connector 2, a joint 3, a pressing mechanism 7, and a baffle 11. When using this device, the three-way connector 2 is connected to the negative pressure device via a flexible hose, and the pagoda-shaped joint 16 is connected to the flexible hose. With the flexible hose facing the patient's stone site, pressing the pressure plate 702 causes it to squeeze the fixing sleeve 705. The spring 703 below the fixing sleeve 705 is compressed, and the screw 704 moves downward. Once the baffle 11, which originally blocked half the inner diameter of the pipe 1, moves downward, upper baffles 12 are fixed on both sides of the baffle 1, effectively blocking the material guide channel 4. At this point, the negative pressure device can be opened. The pressure device absorbs the stones, which enter the pipe 1. The stone filter 18 blocks the stones. Then, the negative pressure device is turned off, and the pipe 1 is kept tilted. At the same time, the pressure on the pressure plate 702 is quickly released. Under the action of the spring 703, the fixing sleeve 705 is lifted and moved upward. The pressure plate 702 deflects clockwise, driving the screw 704 to move upward. This causes the baffle 11 located in the material guide channel 4 to move upward and block half of the pipe 1, thus blocking the stones and preventing them from sliding out of the pagoda joint 16. This effectively solves the problem raised in the background technology, and can intercept and collect the stones after absorption, preventing the stones from flowing back out of the pagoda joint 16 and facilitating operation.
