[0013] This invention provides a device for removing intrahepatic bile duct stones in hepatobiliary surgery. It has the following beneficial effects: 1. This intrahepatic bile duct stone removal device for hepatobiliary surgery utilizes a clamping mechanism to aspirate bile and remove stones.

An insertion tube is set inside the second arc-shaped plate to facilitate the separate collection of bile mixed in with the stone while placing it.
[0016] 4. This hepatobiliary intrahepatic bile duct stone removal device, through its processing components, allows for the selection of either stone removal or bile aspiration. It integrates bile aspiration and stone removal into a single design, with easily adjustable relative positions of the suction tube and clamps, ensuring that the two processes do not interfere with each other. The suction tube length is easily adjustable, and the aspirated bile is contained in the central cylinder. The positions of the four clamps are individually controllable, allowing selection of the appropriate clamp based on the size or shape of the stone. The distance between the clamps is also easily adjustable, and the removed stones are placed in a receiving box. Bile and stones are stored separately for easy subsequent testing.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
[0020] like Figures 1-9 As shown, the present invention provides a technical solution: including a frame plate 1, and further including: The central cylinder 3 is installed inside the frame plate 1; Control mechanism 2 is installed on the outside of the frame plate 1. Control mechanism 2 includes a first outer cylinder 203 and a second outer cylinder 204. The outside of the first outer cylinder 203 is provided with a scale indicator bar and a first push rod 201 is provided on the outside of the first outer cylinder 203. The first push rod 201 is set as an electric push rod and is used to control the merging or separation between the first outer cylinder 203 and the second outer cylinder 204. The clamping mechanism 4 is installed outside the central cylinder 3. The clamping mechanism 4 includes a piston head 401 and an outer ring 402. A processing component 403 is installed outside the outer ring 402. The piston head 401 is installed inside the central cylinder 3, and the outer ring 402 is installed outside the central cylinder 3.
[0021] Before using the device, the user adjusts the control mechanism 2 and the clamping mechanism 4, thereby adjusting the relative position between the central cylinder 3 and the first outer cylinder 203, as well as the angle of the central cylinder 3. Then, the user holds the device and moves it to the bile duct. Before removing the stones, the user selectively uses the clamping mechanism 4 to aspirate and clamp the bile and stones separately, based on the presence of bile shown in the imaging, and then places the bile and stones separately.
[0022] Control mechanism 2 also includes: The connecting frame 202 is composed of an arc-shaped connecting plate and an L-shaped rod. The connecting frame 202 is connected to the telescopic end of the first push rod 201 and to the first outer cylinder 203. The receiving box 205 is installed at the bottom of the first outer cylinder 203, and the receiving component 206 is provided inside the receiving box 205. Handle 207 is installed on the outside of the frame plate 1, and the user holds the handle 207. Positioning strip 208 is provided on the outside of the frame plate 1. Multiple positioning strips 208 are provided and are evenly distributed. Circular grooves 209 are formed inside the frame plate 1. There are four circular grooves 209, which are evenly distributed. The first slide 210 is formed inside the frame plate 1, and four first slides 210 are formed. The first adjustment frame 211 is composed of an electric push rod and a frame body. The first adjustment frame 211 is installed on the outside of the frame plate 1. An annular suction strip is provided on the outside of the frame body. The annular suction strip is attracted and fixed to the central cylinder 3. By adjusting the stroke of the electric push rod inside the first adjustment frame 211, the position of the central cylinder 3 relative to the first outer cylinder 203 can be adjusted. The through groove 212 is opened inside the frame plate 1, and the central cylinder 3 is set inside the through groove 212.
[0023] Before using the device, the first push rod 201 is in its initial state, at which point the first outer cylinder 203 and the second outer cylinder 204 are attached together, and the receiving box 205 is located at the bottom of the second outer cylinder 204. The user can perform the work of grabbing stones or aspirating bile by adjusting the clamping mechanism 4.
[0024] After using the device, activate the first push rod 201. The first push rod 201 drives the connecting frame 202 and the first outer cylinder 203 to move away from the second outer cylinder 204. At this time, the first outer cylinder 203 and the second outer cylinder 204 separate, and the receiving box 205 is located below the gap between them. By adjusting the stroke of the electric push rod in the first adjusting frame 211, the electric push rod drives the frame and the central cylinder 3 to move, thereby adjusting the relative position of the central cylinder 3 and the receiving box 205, and thus placing the stone in the receiving box 205.
[0025] The relative position between the first outer cylinder 203 and the second outer cylinder 204 is adjusted by setting the control mechanism 2. When the first push rod 201 is in the initial state, the first outer cylinder 203 and the second outer cylinder 204 are in contact, and the receiving box 205 is located below the second outer cylinder 204. At this time, the user uses the device to perform stone removal or bile extraction. When the first push rod 201 is in the open state, the first outer cylinder 203 and the second outer cylinder 204 are separated, and the receiving box 205 is located below the gap between the first outer cylinder 203 and the second outer cylinder 204, which facilitates the placement of the removed stones and reduces the number of tools used when removing stones.
[0026] Component 206 includes: The first arc-shaped plate 2061 is disposed at the bottom of the receiving box 205; The second arc-shaped plate 2062 is disposed at the bottom of the receiving box 205, and the first arc-shaped plate 2061 and the second arc-shaped plate 2062 are alternately disposed at the bottom of the receiving box 205. Insertion tube 2063 is installed inside the second arc-shaped plate 2062, and a plug 2064 is provided inside the insertion tube 2063.
[0027] As the stones fall into the receiving box 205, due to the uneven bottom of the receiving box 205, the first arc plate 2061 and the second arc plate 2062 are alternately set. The bile mixed in the stones flows into the insertion tube 2063 through the second arc plate 2062, which facilitates the separation of stones and bile and provides pretreatment for subsequent stone cleaning and inspection.
[0028] By setting up the receiving component 206, the stones are placed, and a first arc-shaped plate 2061 and a second arc-shaped plate 2062 are alternately arranged at the bottom of the receiving box 205. The convex surface of the first arc-shaped plate 2061 faces upward, and the convex surface of the second arc-shaped plate 2062 faces downward. An insertion tube 2063 is set inside the second arc-shaped plate 2062 to facilitate the separate collection of bile mixed in with the stones while placing them.
[0029] The clamping mechanism 4 also includes: The sliding frame 404 is slidably connected inside the first slide groove 210; The second push rod 405 is an electric push rod. The second push rod 405 is installed inside the first slide groove 210. The sliding frame 404 is connected to the telescopic end of the second push rod 405. Connecting rod 406 is slidably connected inside sliding frame 404; The second adjustment frame 407 is composed of an electric push rod and a frame body. The second adjustment frame 407 is installed outside the sliding frame 404 and is connected to the connecting rod 406. The connecting post 408 is slidably connected inside the circular groove 209 and is connected to the outer ring 402.
[0030] Processing component 403 includes: The second slide groove 4031 is formed inside the outer ring 402; Slide 4032 is slidably connected inside the second slide groove 4031, and slide 4032 is connected to the connecting rod 406; Spring 4033 is installed inside the second slide groove 4031 and is connected to slide plate 4032; Connecting rod 4034 is connected to connecting rod 406; Clamping plate 4035, clamping plate 4035 is set in arc shape, and there are four clamping plates 4035. Clamping plate 4035 is connected to connecting rod 4034. Inclined tube 4036, which is connected to the central cylinder 3; The third adjustment frame 4037 is composed of an electric push rod and a frame body, and is installed on the outside of the inclined tube 4036; The straw 4038 is installed outside the inclined tube 4036 and is connected to the third adjustment bracket 4037.
[0031] Before aspirating bile, the electric push rod in the second adjustment frame 407 is activated. The electric push rod drives the frame and connecting rod 406 to move away from the outer ring 402. The connecting rod 406 drives the connecting rod 4034 and the clamping plate 4035 to move closer to the outer ring 402, thus reserving working space for aspirating bile.
[0032] As the user moves the device to the bile duct, the electric push rod in the third adjustment frame 4037 is activated to the corresponding stroke according to the bile location. The electric push rod drives the suction tube 4038 to be pulled away from the inclined tube 4036. Then the user manually pulls the piston head 401 to perform bile suction.
[0033] Before removing the stone, the electric push rod in the second adjusting frame 407 is adjusted to its initial state. The electric push rod drives the frame and connecting rod 406 to move closer to the outer ring 402, while the connecting rod 4034 and clamping plate 4035 move away from the outer ring 402. Based on the size of the stone, the stroke of the second push rod 405 is adjusted. The second push rod 405 drives the sliding frame 404 to move inside the first sliding groove 210, which in turn drives the connecting rod 406 to move. The connecting rod 406 drives the sliding plate 4032 to move inside the second sliding groove 4031. Simultaneously, the connecting rod 406 drives the connecting rod 4034 and clamping plate 4035 to move, thereby adjusting the distance between the four clamping plates 4035 to better match the size of the stone. Finally, by adjusting the stroke of the second push rod 405 and the electric push rod in the second adjusting frame 407, the clamping operation of the clamping plate 4035 and the stone is completed.
[0034] After the stone is removed, the electric push rods in the first adjusting frame 211 and the second adjusting frame 407 are activated. The electric push rod in the first adjusting frame 211 controls the central cylinder 3 to move away from the frame plate 1. The central cylinder 3 drives the processing component 403 to move towards the gap between the first outer cylinder 203 and the second outer cylinder 204. The electric push rod in the second adjusting frame 407 drives the connecting rod 406 to move. The connecting rod 406 drives the clamping plate 4035 and the stone to move until the stone is above the receiving box 205. Then, the stroke of the second push rod 405 is adjusted, and the four clamping plates 4035 move away from the stone, releasing the stone into the receiving box 205.
[0035] The clamping mechanism 4 is used to extract bile and remove gallstones. During gallstone removal, a large amount of bile in the bile duct can adhere to the clamping plate 4035, causing it to slip. This problem is solved by using an adjustable suction tube 4038 to extract the bile, reducing the amount of bile adhering to the clamping plate 4035.
[0036] The processing component 403 allows for the selection of either stone removal or bile extraction. It integrates bile extraction and stone removal into a single design. The relative positions of the suction tube 4038 and the clamping plates 4035 are easily adjustable, ensuring that their operation does not interfere with each other. The length of the suction tube 4038 is easily adjustable, and the extracted bile is contained within the central cylinder 3. The positions of the four clamping plates 4035 are individually controllable, allowing selection of the appropriate plate based on the size or dimensions of the stone. The distance between the clamping plates 4035 is also easily adjustable. The extracted stones are placed in the receiving box 205. The bile and stones are stored separately for easy subsequent testing.
[0037] Working principle: Before using the device, the first push rod 201 is in its initial state. At this time, the first outer cylinder 203 and the second outer cylinder 204 are attached together, and the receiving box 205 is located at the bottom of the second outer cylinder 204. The user can perform the work of grabbing stones or aspirating bile by adjusting the clamping mechanism 4.
[0038] Before aspirating bile, the electric push rod in the second adjustment frame 407 is activated. The electric push rod drives the frame and connecting rod 406 to move away from the outer ring 402. The connecting rod 406 drives the connecting rod 4034 and the clamping plate 4035 to move closer to the outer ring 402, thus reserving working space for aspirating bile.
[0039] As the user moves the device to the bile duct, the electric push rod in the third adjustment frame 4037 is activated to the corresponding stroke according to the bile location. The electric push rod drives the suction tube 4038 to be pulled away from the inclined tube 4036. Then the user manually pulls the piston head 401 to perform bile suction.
[0040] Before removing the stone, the electric push rod in the second adjusting frame 407 is adjusted to its initial state. The electric push rod drives the frame and connecting rod 406 to move closer to the outer ring 402, while the connecting rod 4034 and clamping plate 4035 move away from the outer ring 402. Based on the size of the stone, the stroke of the second push rod 405 is adjusted. The second push rod 405 drives the sliding frame 404 to move inside the first sliding groove 210, which in turn drives the connecting rod 406 to move. The connecting rod 406 drives the sliding plate 4032 to move inside the second sliding groove 4031. Simultaneously, the connecting rod 406 drives the connecting rod 4034 and clamping plate 4035 to move, thereby adjusting the distance between the four clamping plates 4035 to better match the size of the stone. Finally, by adjusting the stroke of the second push rod 405 and the electric push rod in the second adjusting frame 407, the clamping operation of the clamping plate 4035 and the stone is completed.
[0041] After using the device, activate the first push rod 201. The first push rod 201 drives the connecting frame 202 and the first outer cylinder 203 to move away from the second outer cylinder 204. At this time, the first outer cylinder 203 and the second outer cylinder 204 separate, and the receiving box 205 is located below the gap between them. By adjusting the stroke of the electric push rod in the first adjusting frame 211, the electric push rod drives the frame and the central cylinder 3 to move, thereby adjusting the relative position of the central cylinder 3 and the receiving box 205, and thus placing the stone in the receiving box 205.
[0042] After the stone is removed, the electric push rods in the first adjusting frame 211 and the second adjusting frame 407 are activated. The electric push rod in the first adjusting frame 211 controls the central cylinder 3 to move away from the frame plate 1. The central cylinder 3 drives the processing component 403 to move towards the gap between the first outer cylinder 203 and the second outer cylinder 204. The electric push rod in the second adjusting frame 407 drives the connecting rod 406 to move. The connecting rod 406 drives the clamping plate 4035 and the stone to move until the stone is above the receiving box 205. Then, the stroke of the second push rod 405 is adjusted, and the four clamping plates 4035 move away from the stone, releasing the stone into the receiving box 205.
[0043] As the stones fall into the receiving box 205, due to the uneven bottom of the receiving box 205, the first arc plate 2061 and the second arc plate 2062 are alternately set. The bile mixed in the stones flows into the insertion tube 2063 through the second arc plate 2062, which facilitates the separation of stones and bile and provides pretreatment for subsequent stone cleaning and inspection.
