Description
Technical Field
[0001] The utility model relates to the technical field of surgical medical instruments, in particular to a thyroid surgery traction device for laparoscopy. Background Art
[0002] Thyroid surgery involves a range of techniques and is often used to treat conditions such as thyroid dysfunction, thyroid nodules, or thyroid cancer. The thyroid is a gland located in the front of the neck that is responsible for regulating metabolism, energy production, and other functions related to the endocrine system. During thyroid surgery, a retractor can maintain the stability of the surgical field by providing steady traction so that the surgeon can operate more easily without too much intervention. This helps ensure visibility of the surgical field and reduces unnecessary movement and interference during the procedure.
[0003] Traditional thyroid surgical traction devices usually consist of a bracket, a traction device, traction materials, and fixing and adjustment mechanism components. Before the operation begins, the surgeon installs the bracket or fixing frame of the traction device on the operating table or bed and adjusts it according to the surgical area and the patient's position. The traction device of the traction device applies appropriate tension by connecting to a specific part of the thyroid or surgical area. The direction and degree of this tension can be fine-tuned by the adjustment device on the traction device. The tension applied by the traction device helps to stretch and stabilize the surgical area, allowing the surgeon to operate and observe more easily. In thyroid surgery, the use of a traction device can help protect surrounding structures while ensuring the stability and safety of the surgical procedure.
[0004] However, traditional thyroid surgical retractors cannot ensure that the two retractors move stably in opposite directions. Due to the complexity of the anatomical structure and tissue of the surgical area, there may be a situation where the traction force of one hook is greater while the traction force of the other side is insufficient, which will lead to instability and inaccuracy in the surgical operation.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a laparoscopic thyroid surgery traction device, comprising a support plate 1, a support column 3 is fixedly connected to the upper surface of the support plate 1, a hollow block 4 is fixedly connected to one end of the support column 3, a handle 6 is rotatably connected inside the hollow block 4, a hollow column 5 is fixedly connected to the outer wall of the handle 6, a fixed column 7 is slidably connected inside the hollow block 4, both ends of the fixed column 7 are fixedly connected to sliding columns 8, the sliding column 8 is slidably connected inside the hollow column 5, one end of the fixed column 7 is fixedly connected to a fixed block 9, and an auxiliary component is arranged inside the fixed block 9;
[0024] Specifically, the operator will turn the handle 6, which is connected to the hollow column 5. Turning the handle will cause the hollow column 5 to rotate along its axis. This rotational movement is cleverly converted into a sliding movement through the internal design, pushing the sliding column 8 inside the hollow column 5 to slide back and forth. When the sliding column 8 slides inside the hollow column 5, the sliding of the sliding column 8 will further affect the position of the fixed column 7, because the movement path of the fixed column 7 is guided by the internal slide rail of the hollow column 5. The fixed column 7 is connected to the fixed block 9. The sliding of the fixed column 7 directly causes the fixed block 9 to move inside the hollow block 4. The fixed block 9 is a key part of the tractor, and its left and right movement will bring The retractors on both sides of the device move synchronously. When the fixed block 9 moves, the retractors also move with it. These retractors are usually connected to the retractor hooks 20 of the surgical equipment and are used to retract tissues or organs. In this way, the operator can control the position and direction of the retractors very accurately. The design of this mechanism allows precise adjustment of the retractors during surgery, helping doctors to obtain a better field of view and operating space. At the same time, this design also helps to reduce the risk of tissue damage caused by excessive or improper traction. In practical applications, this mechanism can greatly improve the flexibility and accuracy of the operation and provide surgeons with a higher level of control.
[0025] Reference Figure 1 and Figure 3 The auxiliary component includes a rotating column 10, which is rotatably connected to the inside of the fixed block 9, a handle 2 11 is fixedly connected to one end of the rotating column 10, a spring clamp 2 is fixedly connected to the lower surface of the support plate 1, a rotating plate 12 is fixedly connected to the outer wall of the rotating column 10, a rotating block 13 is rotatably connected to the side wall of the rotating plate 12, a rotating plate 2 14 is rotatably connected to the side wall of the fixed block 9, a rotating rod 15 is rotatably connected to the side wall of the rotating plate 12, the rotating plate 2 14 is rotatably connected to the side wall of the rotating block 13, a sliding plate 16 is rotatably connected to the side wall of the rotating block 13, and a rotating rod 2 17 is rotatably connected to the side wall of the rotating plate 2 14;
[0026] Specifically, the operator will turn the handle 2 11, and the handle 2 11 is connected to the rotating column 10, so turning the handle will cause the rotating column 10 to rotate along its axis, and the rotational movement of the rotating column 10 will further affect the movement of other components. The rotating column 10 is connected to the rotating plate 12, so when the rotating column 10 rotates, the rotating plate 12 will also rotate accordingly. The rotational movement of the rotating plate 12 is the core of this process, which converts mechanical movement into corresponding actions of subsequent components. The rotating plate 12 is connected to the rotating block 13, so the rotation of the rotating plate 12 drives the rotating block 13 to rotate together. The rotation of the rotating block 13 is a crucial step in the adjustment mechanism because it affects the movement of subsequent components. The rotating block 13 is connected to the rotating plate 2 14, and when the rotating block 13 rotates, the rotating plate 2 14 will also follow The movement of the rotating plate 14 and the rotating block 13 are synchronized with each other, and they constitute an important part of the adjustment mechanism. At the same time, the rotation of the rotating plate 12 will also drive the rotation of the rotating rod 15, and the rotating rod 15 is connected to the rotating plate 12. Therefore, when the rotating plate 12 rotates, the rotating rod 15 will also rotate accordingly. The rotation of the rotating rod 15 is one of the key steps in the adjustment mechanism. The rotation of the rotating block 13 will also cause the sliding plate 16 to slide inside the hollow plate 19. This sliding is carried out under the control of the rotating block 13, and is intended to achieve the subsequent steps of the mechanism. In addition, the rotation of the rotating plate 14 will also drive the rotation of the rotating rod 17, and the rotating rod 17 is connected to the rotating plate 14. Therefore, when the rotating plate 14 rotates, the rotating rod 17 will also rotate accordingly.
[0027] Reference Figure 1 and Figure 3 The side wall of the rotating rod 17 is rotatably connected to a hollow plate 19, the sliding plate 16 is slidably connected inside the hollow plate 19, the side wall of the rotating rod 15 is rotatably connected to a connecting plate 18, the rotating rod 17 is rotatably connected to the side wall of the connecting plate 18, and the side wall of the connecting plate 18 is fixedly connected to a hook 20;
[0028] Specifically, the movement of the connecting plate 18 is a key step in achieving the forward and backward movement of the hook 20. The movement of the connecting plate 18 is affected by the rotating rod 15 and the rotating rod 2 17, and it moves forward and backward inside the mechanism. Finally, the movement of the connecting plate 18 will drive the forward and backward movement of the hook 20. The hook 20 is the final target of the adjustment mechanism, and its movement completes the entire adjustment process. Through this complex mechanical design, the operator can achieve precise adjustment of the hook 20, thereby meeting the needs of the operation and the doctor's operating requirements. The design of this mechanism not only improves the flexibility and accuracy of the operation, but also helps to reduce the risks and complications during the operation.
[0029] Working principle: When the left and right positions of the hook 20 need to be adjusted, first turn the handle 1 6. The rotation of the handle 1 6 will drive the hollow column 5 to rotate. The rotation of the hollow column 5 will drive the sliding column 8 to slide inside it. The sliding of the sliding column 8 will drive the fixed column 7 to slide inside the hollow block 4 according to the slide rail inside the hollow column 5. The sliding of the fixed column 7 will drive the fixed blocks 9 on both sides to move. At this time, the fixed blocks 9 will drive the tractors on both sides to move in the opposite direction. When the hook 20 needs to be moved forward and backward, first turn the handle 2 11. The rotation of the handle 2 11 will drive the rotating column 10 to rotate. The rotation of the rotating column 10 will drive the rotating plate 1 2 rotates, the rotation of the rotating plate 12 will drive the rotating block 13 to rotate, the rotation of the rotating block 13 will drive the rotating plate 2 14 to rotate, and at the same time, the rotation of the rotating plate 12 will drive the rotating rod 15 to rotate, and the rotation of the rotating block 13 will also drive the sliding plate 16 to slide inside the hollow plate 19, and the rotation of the rotating rod 15 will drive the connecting plate 18 to move, and at the same time, the rotation of the rotating plate 2 14 will drive the rotating rod 2 17 to rotate, and the rotation of the rotating rod 2 17 will assist the movement of the connecting plate 18, and the movement of the connecting plate 18 will drive the hook 20 to move. At this time, the movement of the hook 20 is completed, and the tractor can be fixed in a suitable position by the spring clamp 2.
