Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an adjustable thyroid surgery support device. Background Art

[0002] The thyroid gland is an endocrine gland in the human body. Thyroid disease requires prompt treatment. There are three common treatment methods: surgery, medication, and iodine-131 therapy. Currently, surgical treatment for thyroid disease requires the use of a surgical stent to support the patient's head.

[0003] Due to the complex anatomical structure of the neck, thyroid surgery requires precise exposure of the surgical field and maintaining the stability of the patient's head and neck. Traditional surgical stents cannot flexibly adjust the neck angle (such as tilt and pitch), and manual assistance is required to rotate the patient's head, increasing the operational risk; adjustment relies on manual operation, and doctors need to frequently adjust the equipment, which prolongs the operation time; the patient's head is easily displaced during the operation, requiring additional manpower to fix it, increasing the burden on medical care. Summary of the Invention

[0004] In response to the current technical problems, the present invention provides an adjustable thyroid surgery support device to solve the problems in the prior art.

[0005] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions: An adjustable thyroid surgery support device comprises a base, a lifting plate provided on the base, at least two support columns provided on the lifting plate, the upper ends of the support columns being connected to a head and neck placement mechanism via ball bearings, a Y-axis transmission mechanism being connected below the head and neck placement mechanism, the Y-axis transmission mechanism being capable of adjusting the lateral tilt angle of the head and neck placement mechanism; The lifting plate is connected to a connecting plate, which is arranged in the horizontal direction. An X-direction transmission mechanism is provided on the connecting plate, which can adjust the pitch angle of the head and neck placement mechanism; the connecting plate is also connected to a bed board.

[0006] When using the above technical solution, the person lies on the bed board with the head and neck positioned on the head and neck placement mechanism. Then, according to the surgical requirements, the pitch angle of the head and neck placement mechanism can be adjusted through the X-axis transmission mechanism, and the lateral angle of the head and neck placement mechanism can be adjusted through the Y-axis transmission mechanism. Finally, it is adjusted to an angle position suitable for the surgery. The height of the head and neck placement mechanism is adjusted through the lifting plate to adapt to patients of different heights, avoiding shoulder suspension or excessive cervical flexion caused by traditional fixed-height brackets.

[0007] Preferably, the X-axis transmission mechanism includes an X-axis rotatably connected to the connecting plate, and the X-axis is driven by a first motor. Two electric telescopic rods are respectively connected to both ends of the X-axis, and an angle is formed between the two electric telescopic rods. The lower end of the electric telescopic rod is connected to the X-axis, and the upper end thereof is connected to the head and neck placement mechanism.

[0008] With this arrangement, the first motor starts to drive the X-axis to rotate. The rotation of the X-axis causes the two electric telescopic rods located at the same end of the X-axis to contract and extend respectively. Since the upper end of the electric telescopic rod is connected to the head and neck placement mechanism, the pitch adjustment of the head and neck placement mechanism is achieved.

[0009] Preferably, a pressure sensor is provided at the connection between the electric telescopic rod and the X-axis, and the pressure sensor is electrically connected to the first motor.

[0010] With this setting, the pressure sensor monitors the pressure changes generated when the X-axis rotates in real time to control the electric telescopic rods on both sides to perform corresponding contraction and extension adjustments.

[0011] Preferably, the connection points between the two electric telescopic rods located at the same end of the X-axis and the X-axis are located at the same position on the X-axis.

[0012] Preferably, the head and neck placement mechanism includes a head and neck main board, the upper end of the support column is connected to the head and neck main board, the middle part of the head and neck main board is recessed downward to form a recessed portion, and the recessed portion is adapted to the human head and neck. An arc-shaped connecting plate is provided at one end of the recessed portion, and the arc-shaped connecting plate is connected to the Y-direction transmission mechanism.

[0013] Preferably, the Y-axis transmission mechanism includes a first fixed block connected to the bottom of the head and neck main board, the first fixed block is provided with a second motor, the output shaft of the second motor is connected to the Y-axis, the Y-axis is provided with a second transmission wheel, the second transmission wheel is connected to the transmission block through a second synchronous belt, the transmission block is connected to the arc-shaped connecting plate through a connecting rod, the second synchronous belt is provided with two head and neck silicone pads, the two head and neck silicone pads are symmetrically arranged, and the two head and neck silicone pads can move synchronously with the second synchronous belt.

[0014] With this setting, the second motor starts and drives the Y-axis to rotate. The Y-axis drives the second synchronous belt to rotate through the second transmission wheel. The head and neck silicone pad rotates with the synchronous belt, thereby driving the head and neck to achieve tilt rotation. The split silicone pad can better fit the patient's skin, reduce pressure and improve comfort.

[0015] Preferably, a through slot is provided on the head and neck main board at the position of the lower recess, the second synchronous belt is arranged through the through slot, and the transmission block and the head and neck silicone pad are located above the lower recess.

[0016] Preferably, the transmission block as a whole has a concave arc structure, and the part of the second synchronous belt located at the upper end of the transmission block also has a concave arc structure. A second fixed block is provided on one side of the transmission block near the middle thereof, and a roller is provided on the side of the second fixed block facing the second synchronous belt, and the roller is located above the second synchronous belt.

[0017] In this way, the setting of the second fixed block prevents the second synchronous belt from being offset during the rotation process. On the other hand, the setting of the roller can prevent the second synchronous belt from tilting, and can ensure that the part of the second synchronous belt located at the upper end of the transmission block is always close to the upper end of the transmission block and has a concave arc structure.

[0018] Preferably, a cylinder is provided on the connecting plate in the vertical direction, the movable end of the cylinder is connected to a block, and the bed plate is connected to the block.

[0020] With this arrangement, the lifting plate can move along the guide rod during the lifting process, thereby improving the overall stability of the device.

[0021] Compared with the existing technology, the beneficial effects of the present invention are: the present invention adopts a modular design, which can realize the separate adjustment of the pitch, roll and height of the head and neck placement mechanism, so that the surgical field is fully exposed, while improving the operating efficiency and patient comfort. The present invention can not only be used for thyroid surgery, but also for postoperative rehabilitation treatment, daily training, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] from Figure 3 Combine Figure 2 As can be seen, the X-axis transmission mechanism includes an X-axis 43 rotatably connected to the connecting plate 3. This X-axis 43 is connected to the output shaft of the first motor 41 via a first transmission mechanism 42. The first transmission mechanism 42 includes a first pulley mounted on the output shaft of the first motor 41 and a second pulley mounted on the X-axis 43. The first and second pulleys are connected by a first synchronous belt. In this embodiment, two sets of first transmission mechanisms 42 and first motor 41 are provided, symmetrically located on the X-axis 43 near its ends.

[0029] Two electric telescopic rods 45 are connected to each end of the X-axis 43, forming an angle between them. The lower end of the electric telescopic rod 45 is connected to the X-axis 43, and the upper end is connected to the head and neck support mechanism's head and neck main board 61. The two electric telescopic rods 45 at the same end of the X-axis 43 are connected to the X-axis 43 at the same location on the X-axis 43. A pressure sensor is also installed at the connection between the electric telescopic rod 45 and the X-axis 43. This pressure sensor is electrically connected to the first motor 41 and has an accuracy of ±0.1N. The pressure sensor, combined with the first motor, can dynamically adjust the support angle.

[0030] refer to Figure 4The head and neck placement mechanism includes a head and neck main board 61. The upper end of the support column 22 is connected to the head and neck main board 61 through a ball bearing. The middle part of the head and neck main board 61 is recessed downward to form a concave portion, which is adapted to the human head and neck. An arc-shaped connecting plate 64 is provided at one end of the concave portion, and the arc-shaped connecting plate 64 is connected to the Y-axis transmission mechanism. A shoulder and neck silicone pad 66 is provided at one end of the head and neck main board 61 away from the arc-shaped connecting plate 64. Four fixed rods 63 are symmetrically distributed below the head and neck main board 61 near both ends. In this embodiment, the fixed rods 63 are L-shaped. The four electric telescopic rods 45 at both ends of the X-axis 43 are respectively connected to the fixed rods 63 at corresponding positions.

[0031] Figure 6 Combine Figure 4 It can be seen that the Y-axis transmission mechanism includes a first fixed block 51 fixedly connected to the bottom of the head and neck main board 61. The first fixed block 51 is specifically located below the lower recess. A second motor 52 is provided on the first fixed block 51 in the horizontal direction. The output shaft of the second motor 52 is connected to the Y-axis shaft 53. A second transmission wheel is provided on the Y-axis shaft 53. The second transmission wheel is connected to the transmission block 55 via a second synchronous belt 54. The transmission block 55 is connected to the arc-shaped connecting plate 64 via two connecting rods 56. The second synchronous belt 54 is provided with two head and neck silicone pads 65. The two head and neck silicone pads 65 are symmetrically arranged and can move synchronously with the second synchronous belt 54. A through slot 62 is provided on the head and neck main board 61 at the position of the lower recess. The second synchronous belt 54 is arranged through the through slot 62. The transmission block 55 and the head and neck silicone pad 65 are located above the lower recess.

[0032] In this embodiment, the transmission block 55 has a concave arc-shaped structure as a whole, and the portion of the second synchronous belt 54 located above the transmission block 55 is close to the upper end of the transmission block 55. Therefore, the portion of the second synchronous belt 54 located at the upper end of the transmission block 55 also has a concave arc-shaped structure. A second fixed block 57 is provided on one side of the transmission block 55 near the middle thereof. A roller 58 is provided on the side of the second fixed block 57 facing the second synchronous belt 54, and the roller 58 is located above the second synchronous belt 54.

[0033] During use, the patient lies on the bed board 7 with the head and neck located on the head and neck silicone pad 65 of the head and neck placement mechanism. At the same time, the height of the head and neck placement mechanism can be adjusted by adjusting the height of the lifting plate 2, so that the patient can lie more comfortably and avoid hanging shoulders or excessive flexion of the cervical spine. Then the first motor 41 is started to drive the X-axis 43 to rotate. When the X-axis 43 rotates, the two electric telescopic rods 45 located at the same end of the X-axis will be driven to contract and extend respectively. Since the upper end of the electric telescopic rod 45 is connected to the head and neck placement mechanism, the pitch adjustment of the head and neck placement mechanism is realized, and the pitch angle is ±30°, which fully exposes the isthmus and lateral lobes of the thyroid gland, reduces the frequency of using retractors during surgery, and avoids excessive traction leading to postoperative Pain; the second motor 52 starts to drive the Y-axis 53 to rotate, and the Y-axis 53 drives the second synchronous belt 54 to rotate through the second transmission wheel. The head and neck silicone pad 65 follows the rotation of the second synchronous belt 54 to drive the head and neck to tilt, with a tilt angle of ±15°. During unilateral thyroid surgery, the tilt angle adjustment improves the symmetry of the surgical field by 40%, reducing the risk of accidental nerve injury due to body position deviation; this solution fully exposes the patient's surgical field through three-degree-of-freedom (pitch, roll, height) linkage adjustment, and improves operational efficiency and patient comfort. At the same time, it has a wide range of usage scenarios, and can be used not only for thyroid surgery, but also for postoperative rehabilitation treatment, daily training, etc.

It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
