[0002] At present, when a patient undergoes a bile duct resection operation, the bile duct needs to be resected first. However, since the diameter of the bile duct is different everywhere, after a section of the bile duct is removed, when it needs to be sutured, due to the different diameters of the bile duct, the bile duct needs to be cut so that the circumference of the two ports of the bile duct is equal. However, it is usually manually visually inspected, and then directly cut with medical scissors, and then the two ends of the bile duct are clamped with surgical clips, and then the two ports are brought close, and then sutured. However, there is often a large error in the visual distance. After suturing, there is often a situation where one end of the opening is too large and the other end is too small. At this time, it may be necessary to cut again so that the two ports completely overlap, which is easy to cause secondary damage to the patient, increase the length of the bile duct resection, and is more unfavorable for the re-healing of the bile duct, increasing the potential risks of the operation, and when clamping with surgical forceps, a single medical staff needs to operate with both hands, but there is shaking between the two ports, errors are prone to occur during suturing, and the distance between the two ports cannot be guaranteed to be constant, which increases the difficulty of the operation and easily leads to excessive mental exhaustion of medical staff, which is not conducive to the smooth progress of the operation.

A fourth spring is provided between the upper clamping plate 3 and the lower clamping plate 2, and buffer grooves are respectively opened on the left and right sides of the main body 1, and the buffer groove is located between the two lifting grooves.
[0034] In order to limit the movement of the sliding plate 4 , the main body 1 is threadedly connected with a screw rod 23 in an upper and lower axial direction. The screw rod 23 penetrates the main body 1 and can contact the sliding plate 4 .
[0035] When the present invention is in use, when it is necessary to suture the patient's bile duct, the right end of the device is inserted into the patient's body, the diameter difference between the two ducts is distinguished by the naked eye, the rear fixed rod 6 and the sliding rod 8 are inserted into the end of the bile duct with a larger diameter, and the front fixed rod 6 and the sliding rod 8 are inserted into the end of the bile duct with a smaller diameter, so that the free end of the bile duct with a smaller diameter contacts the cutter 15, and then the two sections of the bile duct are respectively placed between the lower splint 2 and the upper splint 3 on their corresponding sides, so that the right side of the bile duct contacts the fixed rod 6.
[0036] Pull the pull ring, the pull ring drives the second connecting rope 16 to move to the left, the second connecting rope 16 drives the pulling plate 5 to move to the left, the pulling plate 5 drives the moving column to move inward through the inclined part of the sliding groove 20, since the upper splint 3 and the lower splint 2 are slidably connected, the upper end of the upper splint 3 is inserted into the lifting groove, which can prevent the upper splint 3 and the lower splint 2 from moving inward during this process, the moving column drives the upper splint 3 to move downward along the lower splint 2 on its corresponding side through the pull rope 19, and the fourth spring is compressed.
[0037] After the upper splint 3 and the lower splint 2 clamp the bile duct on their corresponding sides, continue to pull the pull ring, the pull ring drives the pulling plate 5 to move to the left through the second connecting rope 16, the pulling plate 5 drives the moving block 17 to move to the left through the first connecting rope, the moving block 17 drives the push rod 18 to move to the left, the push rod 18 pushes the sliding block 7 on its corresponding side to move to the left, at this time the moving column enters the horizontal part of the sliding groove 20, the upper splint 3 and the lower splint 2 will not hinder the movement of the pulling plate 5, the sliding block 7 drives the insertion rod 13 on its corresponding side to move to the left, the sliding block 7 drives the sliding rod 8, the moving rod 10, the connecting rod 9, the connecting rod and the auxiliary rod to move to the left, the insertion rod 13 drives the moving plate 11 to move to the left through the lifting rod 14 and the pushing groove 12 on its corresponding side, and the moving plate 11 drives the baffle and the cutter 15 to move to the left.
[0038] Continue to pull the pull ring to move to the left, the lifting rod 14 and the insertion rod 13 continue to move to the left, after the front connecting rod 9 moves to a certain position to the left, the connecting rod 9 on the left contacts the inner wall of the bile duct, and then the connecting rod 9 starts to swing to the right, the connecting rod 9 drives the moving rod 10 to move inward through the connecting rod, and the moving rod 10 drives the limiting plate 21 to move out of the notch groove on the corresponding side, and no longer restricts the front insertion rod 13. The front insertion rod 13 is inserted into the slot on the corresponding side under the action of the second spring, and the insertion rod 13 is inserted into the slot on the corresponding side through the second spring. The third spring drives the lifting rod 14 on its corresponding side to move downward, so that the upper end of the lifting rod 14 on the front side moves out of the pushing groove 12, restricting the movement of the sliding block 7 on the front side, and will not hinder the movement of the moving plate 11 and the sliding block 7 on the rear side. When the moving rod 10 moves inward, the moving rod 10 drives the front push rod 18 to move inward, and the first spring on the front side is compressed, so that the front push rod 18 no longer contacts the right end of the sliding block 7 on its corresponding side. At this time, the bile duct on the front side is completely opened.
[0039] Continue to pull the pull ring, the moving block 17 drives the sliding block 7 on the rear side to move to the left through the push rod 18 on the rear side, and the sliding block 7 continues to drive the connecting rod 9, the sliding rod 8, the connecting rod, the insertion rod 13 and the lifting rod 14 to move to the left. At this time, since the sliding block 7 on the front side is provided with a baffle, it can prevent the moving plate 11 from continuing to move to the left, and the insertion rod 13 begins to drive the moving plate 11 to move forward through the pushing groove 12 on the rear side, and the angle between the pushing groove 12 and the side of the moving plate 11 is 45 degrees, which can make the moving plate 11 move forward The distance equal to the distance the insertion rod 13 moves to the left, when the insertion rod 13 on the rear side moves to the left, the moving plate 11 drives the cutter 15 to move forward and cuts the bile duct on the front side. Since the bile duct on the front side is completely opened at this time, no displacement will occur during cutting.
[0040] When the connecting rod 9 on the rear side contacts the inner wall of the bile duct on its corresponding side, the connecting rod 9 on the rear side drives the moving rod 10 to move inward through the connecting rod on its corresponding side, and the moving rod 10 drives the limiting plate 21 to move inward and move out of the notch groove on its corresponding side. The insertion rod 13 moves downward under the action of the second spring. Since the lifting rod 14 is longer, it will not move out of the pushing groove 12 on the rear side. The insertion rod 13 on the rear side is inserted into the slot on its corresponding side to limit the movement of the sliding block 7 on the rear side. At the same time, the moving rod 10 on the rear side pushes the push rod 18 on the rear side to move inward, and the second spring on the rear side is compressed. Since the bile duct on the front side is fully opened at this time, the distance that the cutter 15 moves forward is equal to the width difference between the two bile ducts, completing the cutting of the bile duct on the front side, and the pull ring cannot be pulled.
[0041] Then pull the auxiliary rod on the rear side upwards, so that the auxiliary rod drives the insertion rod 13 on the rear side to move upwards, and the insertion rod 13 on the rear side moves upwards out of the slot, and then push the auxiliary rod to the right, the auxiliary rod drives the insertion rod 13 and the lifting rod 14 to move to the right, the lifting rod 14 drives the moving plate 11 to move backwards through the pushing groove 12 on the rear side, the moving plate 11 drives the cutting knife 15 to move backwards, and at the same time the insertion rod 13 drives the sliding block 7 to move to the right, after the connecting rod 9 is no longer in contact with the bile duct, under the action of the third spring, the push rod 18 on the rear side drives the moving rod 10 to move backwards, the moving rod 10 drives the connecting rod 9 to swing to the left to the initial position through the connecting rod, and the moving rod 10 drives the limiting plate 21 into the notch groove on its corresponding side to limit the movement of the insertion rod 13 on the rear side.
[0042] When the sliding block 7 on the rear side is moved to the right to a position where it cannot move, the insertion rod 13 on the front side is located directly below the insertion rod 13, and the auxiliary rod on the front side is pulled upward, so that the insertion rod 13 on the front side drives the lifting rod 14 to move upward, and the second spring is compressed, so that the insertion rod 13 on the front side is moved out of the slot on its corresponding side, and the upper end of the lifting rod 14 is inserted into the pushing groove 12 on its corresponding side, and then the two auxiliary rods are pushed to the right. When the connecting rod 9 on the front side is no longer in contact with the bile duct, the push rod 18 on the front side pushes the moving rod 10 to move forward under the action of the third spring, and the moving rod 10 is connected to the The rod drives the connecting rod 9 to swing to the left, and at the same time the limiting plate 21 on the front side is inserted into the limiting groove to limit the insertion rod 13 on the front side. Then, under the action of the first tension spring, the moving block 17 moves to the right. Since the front push rod 18 of the front end is located to the left of the sliding block 7 on its corresponding side at this time, the right end face of the front push rod 18 is an arc-shaped surface. When the sliding block 7 moves to the left, the arc-shaped surface of the push rod 18 is squeezed by the sliding block 7, the first spring is compressed, and the push rod 18 moves from the rear of the sliding block 7 to the right of the front sliding block 7, and then the sliding block 7 and the cutter 15 are moved to the initial position.
[0043] Then, the screw rod 23 is rotated to release the restriction on the sliding plate 4, and then the sliding plate 4 is pushed to the left, so that the sliding plate 4 drives its internal structure to move to the left into the main body 1. After the sliding plate 4 is moved to a certain position to the left, the sliding plate 4 begins to retract inwardly through the pulling column 22 to drive the pull rope 19, and the pull rope 19 begins to drive the upper splint 3 and the lower splint 2 to move inwardly, so that the ports of the two bile ducts are in contact. At this time, the upper splint 3 and the lower splint 2 have not entered the buffer groove, and then the ports of the bile duct are sutured. After the suturing is completed, the upper splint 3 and the lower splint 2 are pushed inwardly into the buffer groove on their corresponding sides, and then under the action of the fourth spring, the upper splint 3 moves upward, and then the sutured bile duct is taken out, and then the device can be reset as a whole.
[0044] The invention has the advantages of simple structure, convenient operation, novel concept and strong practicality. It is provided with a main body, a lower clamping plate, an upper clamping plate, a lifting groove, a pull rope, a second connecting rope, a sliding plate, a movable column, a through groove, a pulling plate, a sliding groove and a pull ring. The upper clamping plate can be moved up and down to clamp the bile duct, and the lower clamping plate and the upper clamping plate on the corresponding side can be moved inward to make the openings of the two bile ducts close to each other, so as to facilitate the suturing of the bile duct. The sliding plate, the pulling plate, the first connecting rope, the second connecting rope, the sliding plate, the movable column, the through groove, the pulling plate, the sliding groove and the pull ring can be moved up and down to clamp the bile duct, and the lower clamping plate and the upper clamping plate on the corresponding side can be moved inward to make the openings of the two bile ducts close to each other, so as to facilitate the suturing of the bile duct. Blocks, fixed rods, sliding rods, connecting rods, connecting rods, plug rods, slots, lifting rods, screws, auxiliary rods, push grooves, notched grooves, limit plates, movable blocks, push rods, cutters, and baffles can not only pull the bile duct to make the bile duct in a taut state, but also cut the bile duct with a smaller diameter to make the circumferences of the openings of the two bile ducts equal, which is convenient for suturing the openings of the bile ducts, is conducive to better growth of the bile duct, reduces the probability of blockage of the bile duct, and increases the convenience and practicality of the device.
