Description

Technical Field

[0001] The invention relates to the technical field of surgical bed frames, and in particular to a bed frame used in breast surgery. Background Art

[0002] A breast surgery bed frame is a medical device designed specifically for breast surgery; it meets the need for precise adjustment of the patient's position during surgery, ensures good exposure of the surgical area, and provides stable and comfortable support. Modern breast surgery bed frames are usually equipped with adjustable height, tilt and lateral movement functions so that surgeons can perform surgical operations at the best angle, while reducing surgical time and increasing surgical success rates. These bed frames also focus on patient comfort and are ergonomically designed to reduce discomfort caused by long surgeries.

[0003] Breast surgery usually requires a good field of vision and operating space. If the chest position on the table cannot be adjusted and raised, it will affect the surgeon's operating angle and field of vision, thereby affecting the accuracy and effect of the surgery. At the same time, different breast surgeries require different body positions to ensure the smooth progress of the operation. If the chest position of the table cannot be raised or lowered, the patient's body position cannot be accurately adjusted, which in turn affects the patient's comfort and even causes discomfort after surgery. In addition, during breast surgery, the doctor needs to adjust the patient's position according to the requirements of the operation. If the chest position of the table does not have a lifting function, it will increase the difficulty of the operation and may prolong the operation time. Postoperative body position adjustment is crucial to recovery. If the chest position of the table cannot be adjusted, it will affect postoperative care and patient comfort, and the doctor may need to maintain a specific posture for a long time during the operation, which will make the working posture less than ideal, thereby increasing fatigue and discomfort. In addition, when the patient adjusts his body on the operating table, the position of the bandage will be offset and wrinkled, which will make it inconvenient to wrap the bandage at the end and will also cause further damage to the wound.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs a bed frame for breast surgery to solve the above technical problems. Summary of the invention

[0006] In order to achieve the above technical objectives, the present invention provides the following technical solutions: The present invention provides a bed frame for breast surgery, comprising a base, a lifting column, a table and an adjustment mechanism, characterized in that a lifting column is installed above the base, a table is installed above the lifting column, and an adjustment mechanism is installed inside the table, the adjustment mechanism drives the horizontal movement of the driven rack through the rotation of the rotating cylinder, and the horizontally moving driven rack drives the vertical movement of the extrusion rod under the action of the support block, so as to adjust the spacing between the side of the table and the extrusion rod, and the clamping force of the extrusion rod on the bandage is adjusted by the distance between the table and the extrusion rod; and the rotational kinetic energy of the arm cylinder is converted into the horizontal kinetic energy of the adjustment cylinder, and the adjustment cylinder with the horizontal kinetic energy drives the transmission bevel gear to move vertically, and the vertically moving transmission bevel gear drives the lifting block to move vertically, and then the vertically moving lifting block squeezes the cross bar on the table to move vertically, and then the vertically moving cross bar adjusts the vertical distance between the extrusion plate and the table, and the vertical distance is used to adjust the protrusion height between the breasts, so that it can be used for the surgical needs of different patients.

[0007] Preferably, the adjustment mechanism can realize the adjustment of the spacing between the table and the extrusion rod and the vertical distance between the extrusion plate and the table; this adjustment can meet the surgical needs of different patients, improve the adaptability and flexibility of the surgery, and the design of the rotating cylinder and the adjustment cylinder can accurately control the clamping force of the extrusion rod on the bandage and the bulge height between the chest during the operation. Accurate adjustment can improve the accuracy and effect of the operation. The adjustment mechanism realizes complex adjustment by rotation and horizontal movement, but the operation method is simple, which is easy for the doctor to make quick adjustments during the operation, reducing the preparation time for the operation and the adjustment time during the operation. Through the fine adjustment of the bulge height of the chest and the clamping force of the bandage, the surgical operation can be better coordinated, the unnecessary squeezing and damage to the patient can be reduced, and the safety of the operation can be improved. The adjustable design makes the bed frame suitable for patients with different body shapes and different surgical needs, has strong adaptability, and can be widely used in breast surgery. Complex surgical requirements can be achieved through simple adjustment, reducing the preparation and adjustment time for the operation, and improving the overall surgical efficiency.

[0008] The adjustment mechanism includes a limit column, a rotating cylinder, a limit column, a fixed cylinder, an adjustment cylinder, an arm cylinder, a driven rack and a transmission column. The limit column is installed on the side of the table top, the rotating cylinder is installed on the limit column, the limit cylinder is installed on the side of the rotating cylinder, the fixed cylinder is installed in an array on the side of the limit cylinder, a limit groove is provided inside the fixed cylinder, an adjustment groove is provided on the middle fixed cylinder, an adjustment cylinder is installed at the center of the fixed cylinder, arm cylinders are installed in an array on the adjustment cylinder, and the fixed cylinder and the arm cylinder are arranged at intervals.

[0009] Preferably, the interval arrangement design of the fixed cylinder and the arm cylinder can evenly distribute the gravity of the arm board, improve the stability of the arm board, thereby increasing the stability of the entire operating bed frame and ensuring safety during the operation. The design of the limit column, limit cylinder and limit groove provides multiple limit protections, avoids excessive adjustment or misoperation during the adjustment process, and ensures the safety and reliability of the adjustment process.

[0010] An annular groove is provided on the limiting column above the rotating cylinder, and the annular groove is used to limit the vertical height of the transmission gear to prevent the transmission gear from moving. A transmission gear is installed on the annular groove, and a transmission groove is provided in an array on the lower surface of the transmission gear. The transmission groove of the array and the transmission block increase the friction between the movable plate and the transmission gear, and then the transmission gear is driven to rotate by the friction, and the rotating gear drives the driven rack to move horizontally. An extrusion airbag is installed on the limiting column below the rotating cylinder, and a transmission airbag is installed below the extrusion airbag. A flow groove is provided on the limiting column between the extrusion airbag and the transmission airbag.

A transmission bevel gear is installed above the transmission airbag, and the side of the transmission bevel gear with the gear faces upward.

[0011] Preferably, an annular groove is provided on the limiting column above the rotating cylinder to limit the vertical height of the transmission gear, thereby preventing the transmission gear from moving unnecessarily, thereby improving the stability of the transmission. The transmission groove array on the lower surface of the transmission gear increases the friction between the moving plate and the transmission gear, and the rotation of the transmission gear is driven by this friction, thereby ensuring the effectiveness and smoothness of the transmission. The extrusion airbag and the transmission airbag are connected by the flow groove on the limiting column, and the linkage between the airbags is realized by gas transmission. This design can accurately control the expansion and contraction of the airbag during the operation, thereby realizing the vertical movement of the transmission bevel gear, and improving the flexibility and accuracy of the adjustment. Through the extrusion of the extrusion airbag by the recovery plate, the gas enters the transmission airbag through the flow groove, and the expansion of the transmission airbag drives the vertical movement of the transmission bevel gear, thereby realizing the automated adjustment function and reducing the complexity and error of manual operation. The transmission bevel gear meshes with the bevel gear on the transmission column, realizing efficient power transmission, ensuring the response speed and adjustment accuracy of the adjustment mechanism, and improving the overall transmission efficiency.

The recovery spring is located between the inner wall of the limit cylinder and the recovery block. Through the elastic force, the safety and stability of the transmission system during use are guaranteed, and the system failure caused by operating errors or unexpected situations is avoided. The extrusion airbag is used in conjunction with the recovery plate to improve the comfort and safety of the patient during the operation. The limit cylinder provides multiple limit protections to prevent excessive movement or misoperation of the transmission components during the adjustment process, ensuring the safe and reliable operation of the entire system. The position of the transmission block corresponds to the transmission groove one by one, which increases the friction between the moving plate and the transmission gear, ensures the stability and reliability of the transmission process, and improves the overall transmission efficiency. The recovery block and the recovery plate can quickly return to the initial state after stopping the operation, which is convenient for the next operation and improves the work efficiency and system reliability.

[0016] The arm tube is provided with a sliding groove, the depth of which gradually becomes shallower from bottom to top, and one end below the sliding groove becomes deeper in a cliff-like manner, and an arm plate is installed on the side of the arm tube.

[0017] Preferably, the depth of the sliding groove gradually becomes shallower from bottom to top, making the adjustment process more refined, and can be fine-tuned according to actual needs, improving the precision and accuracy of the adjustment, and meeting the surgical needs of different patients.

Through the precise adjustment of the operating bed frame, it can better cooperate with the surgical operation, improve the success rate and effect of the operation, and reduce the risk of surgery.

[0035] like Figure 3 and 4As shown, an annular groove 411 is provided on the limiting column 41 above the rotating cylinder 42, and the annular groove 411 is used to limit the vertical height of the transmission gear 412 to prevent the transmission gear 412 from moving. The transmission gear 412 is installed on the annular groove 411, and the lower surface of the transmission gear 412 is provided with a transmission groove 413 in an array. The transmission groove 413 of the array and the transmission block 434 increase the friction between the moving plate 433 and the transmission gear 412, and then the transmission gear 412 is driven to rotate by the friction force. The rotating gear drives the driven rack 47 to move horizontally. An extrusion airbag 414 is installed on the limiting column 41 below the rotating cylinder 42, and a transmission airbag is installed below the extrusion airbag 414. The extrusion airbag 414 and the transmission airbag 415 are provided with a flow groove 416 on the limiting column 41, and the gas between the extrusion airbag 414 and the transmission airbag 415 is transmitted by the flow groove 416 on the limiting column 41, and the extrusion airbag 414 is squeezed by the recovery plate 438, and the gas inside the extrusion airbag 414 enters the transmission airbag 415 through the flow groove 416 to expand, and the expanded transmission airbag 415 drives the transmission bevel gear 417 to move vertically, and the vertically moving transmission bevel gear 417 is meshed with the bevel gear on the transmission column 48, and a transmission bevel gear 417 is installed above the transmission airbag 415, and the gear side of the transmission bevel gear 417 faces upward.

[0036] By setting an annular groove 411 on the limiting column 41 above the rotating cylinder 42, the vertical height of the transmission gear 412 is limited to prevent the transmission gear 412 from moving unnecessarily, thereby improving the stability of the transmission. The transmission groove 413 arranged in an array on the lower surface of the transmission gear 412 increases the friction between the moving plate 433 and the transmission gear 412. The rotation of the transmission gear 412 is driven by this friction, ensuring the effectiveness and smoothness of the transmission. The extrusion airbag 414 and the transmission airbag 415 are connected by the flow groove 416 on the limiting column 41, and the linkage between the airbags is realized by gas transmission. This design can accurately control the expansion and contraction of the airbag during the operation, thereby realizing the vertical movement of the transmission bevel gear 417, and improving the flexibility and accuracy of the adjustment. Through the extrusion of the extrusion airbag 414 by the recovery plate 438, the gas enters the transmission airbag 415 through the flow groove 416, and the expansion of the transmission airbag 415 drives the transmission bevel gear 417 to move vertically, realizing the automatic adjustment function and reducing the complexity and error of manual operation. The transmission bevel gear 417 meshes with the bevel gear on the transmission column 48, achieving efficient power transmission, ensuring the response speed and adjustment accuracy of the adjustment mechanism 4, and improving the overall transmission efficiency. The design of the transmission bevel gear 417 allows one side of the gear to face upward, which is more conducive to meshing with the bevel gear on the transmission column 48, providing stable power transmission and ensuring the smoothness of the adjustment action.

[0037] like Figure 2 and 3 As shown, a moving block 431 is installed on the upper part of the inner part of the limiting cylinder 43, and the cross-sectional shape of the moving block 431 is a trapezoid. A moving cylinder 432 is installed on the trapezoidal moving block 431, and a moving plate 433 is installed on the moving cylinder 432, and the moving plate 433 is also located below the transmission gear 412. Transmission blocks 434 are installed in an array on the moving plate 433, and the positions of the transmission blocks 434 and the transmission grooves 413 correspond one to one. A recovery block 435 is installed on the lower part of the inner part of the limiting cylinder 43, and a recovery cylinder 436 is installed on the recovery block 435. A recovery spring 437 is installed on the side of the recovery cylinder 436, and the recovery spring 437 is located between the inner wall of the limiting cylinder 43 and the recovery block 435. A recovery plate 438 is installed on the other end of the recovery cylinder 436, and the recovery plate 438 is located above the extrusion airbag 414.

[0038] The trapezoidal design of the moving block 431 and the one-to-one correspondence between the transmission block 434 on the moving plate 433 and the transmission slot 413 ensure the accuracy and stability of the transmission process and improve the accuracy of the adjustment. The recovery spring 437 provides a stable elastic force, so that the recovery block 435 and the recovery plate 438 can quickly return to the initial position, thereby improving the response speed and efficiency of the adjustment device. The recovery spring 437 is located between the inner wall of the limit cylinder 43 and the recovery block 435. Through the elastic force, the safety and stability of the transmission system during use are guaranteed, and the system failure caused by operating errors or unexpected situations is avoided. The extrusion airbag 414 is used in conjunction with the recovery plate 438 to improve the comfort and safety of the patient during the operation. The limit cylinder 43 provides multiple limit protections to prevent excessive movement or misoperation of the transmission components during the adjustment process, thereby ensuring the safe and reliable operation of the entire system. The transmission block 434 corresponds to the position of the transmission slot 413 one by one, which increases the friction between the moving plate 433 and the transmission gear 412, ensures the stability and reliability during the transmission process, and improves the overall transmission efficiency. The recovery block 435 and the recovery board 438 can be quickly restored to the initial state after stopping the operation, which is convenient for the next operation and improves the work efficiency and system reliability.

[0039] like Figure 3 As shown, the adjusting cylinder 45 is provided with limit blocks 451 in an array, and the limit blocks 451 are located in the adjusting groove 442; the adjusting cylinder 45 is provided with extrusion rings 452 in an array, and the extrusion rings 452 are located inside the adjusting groove 442; the side of the extrusion ring 452 is clamped with an adjusting spring 453, and the other end of the adjusting spring 453 is clamped on the fixed cylinder 44; two tilting blocks 454 are provided on the side of the adjusting cylinder 45 close to the rotating cylinder 42, and the tilting blocks 454 are located on the side of the center line of the adjusting cylinder 45, and the inclined surfaces of the two tilting blocks 454 are arranged face to face.

[0040] The limit block 451 is installed in the adjustment groove 442 to effectively limit the movement of the adjustment tube 45, preventing the adjustment tube 45 from excessive movement or position deviation, thereby improving the stability and reliability of the adjustment process. The extrusion ring 452 is installed inside the adjustment groove 442 and is connected to the fixed tube 44 through the adjustment spring 453, so that the pressure in the adjustment process can be accurately controlled, ensuring the accuracy and stability of the adjustment operation to meet different surgical needs. After the adjustment process is completed, the adjustment spring 453 can automatically reset the extrusion ring 452, simplifying the operation process, reducing the surgical preparation and adjustment time, and improving work efficiency. The design of the limit block 451 and the adjustment spring 453 makes the adjustment operation easier, and medical staff can easily adjust, reducing the difficulty of operation and improving surgical efficiency. The design of the extrusion ring 452 and the adjustment spring 453 makes the entire adjustment mechanism 4 more compact, reduces the volume and weight of the equipment, and is easy to operate and move. The design of the adjustment spring 453 and the limit block 451 reduces the wear and damage of the adjustment mechanism 4, extends the service life of the equipment, and reduces maintenance costs.

[0041] like Figure 2 , 3 As shown in FIG. 4 , a sliding groove 461 is provided on the arm tube 46 . The depth of the sliding groove 461 gradually becomes shallower from bottom to top, and the end below the sliding groove 461 becomes deeper in a cliff-like manner. An arm plate 462 is installed on the side of the arm tube 46 .

[0042] The design of the sliding groove 461 gradually becoming shallower from bottom to top makes the adjustment process more refined, can be fine-tuned according to actual needs, improves the precision and accuracy of the adjustment, and meets the surgical needs of different patients. The end below the sliding groove 461 is a cliff-like deepening design, which provides an effective limit function to prevent the arm tube 46 from excessive movement or detachment during the sliding process, and ensures the stability and safety of the adjustment process. The adjustment of the arm tube 46 is achieved through the sliding groove 461, and the operation is simple and intuitive. Medical staff can easily adjust it, reducing the time for surgical preparation and adjustment, and improving surgical efficiency. The arm plate 462 is installed on the side of the arm tube 46. Through the design of the sliding groove 461, the multi-angle adjustment of the arm plate 462 can be achieved to meet the needs of different surgical positions and improve the flexibility and adaptability of the operation. The design of the sliding groove 461 reduces the friction between the arm tube 46 and other components, reduces the wear and damage of the equipment, extends the service life of the equipment, and reduces the maintenance cost. It can be adjusted according to the patient's body shape and surgical needs, reducing the pressure and discomfort of the patient, and improving the patient's comfort during the operation. The design of the sliding groove 461 and the arm plate 462 makes the structure of the adjustment mechanism 4 more compact, reduces the volume and weight of the device, facilitates operation and movement, and saves space in the operating room. The cliff-like depth change design provides additional limit protection to prevent the arm tube 46 from accidentally detaching during the sliding process, thereby increasing the safety and reliability of the operation.

[0043] like Figure 5 and 6 As shown, the driven rack 47 is meshed with the transmission gear 412, and the driven rack 47 is located at the inner end of the transmission gear 412, the cross-sectional shape of the driven rack 47 is L-shaped, and an extrusion block 471 is installed at the left end of the driven rack 47, and the upper end cross-sectional shape of the extrusion block 471 is a right-angled trapezoid, and an isosceles trapezoidal block 472 is installed on the inclined surface of the extrusion block 471, and a right-angled block 473 is installed on the inclined surface of the extrusion block 471, and an isosceles trapezoidal groove 474 is provided on the inclined surface of the right-angled trapezoidal block, and support blocks 475 are installed on the upper and lower surfaces of the right-angled trapezoidal block, and an extrusion rod 476 is installed on the left side of the right-angled trapezoidal block.

[0044] The driven rack 47 meshes with the transmission gear 412 to ensure the efficiency and stability of the transmission process. The L-shaped driven rack 47 is designed to better transmit power and improve the transmission efficiency of the entire system. The design of the L-shaped driven rack 47 allows it to be compactly arranged at the inner end of the transmission gear 412, saving space, making the overall structure more compact and suitable for use in limited spaces such as operating rooms. The extrusion block 471 is designed as a right-angled trapezoid, and isosceles trapezoidal blocks 472 and right-angled blocks 473 are installed on its inclined surface, which can provide multi-angle and multi-directional extrusion functions. The inclined surface of the right-angled trapezoidal block is provided with an isosceles trapezoidal groove 474, so that the right-angled trapezoidal block can be accurately positioned, ensuring the stability and accuracy of the extrusion block 471 during use, and reducing the possibility of misoperation. Support blocks 475 are installed on the upper and lower surfaces of the right-angled trapezoidal block, providing additional support force, improving the stability and bearing capacity of the entire clamping, and ensuring stable operation during surgery. The squeezing rod 476 is installed on the left side of the right-angled trapezoidal block. By adjusting the squeezing rod 476, the squeezing force can be precisely controlled to ensure proper squeezing of the patient's chest, thereby improving the patient's comfort and safety. The rational design of the driven rack 47, squeezing block 471, isosceles trapezoidal block 472 and right-angle block 473 makes the entire adjustment operation easier, and medical staff can easily make adjustments, thereby improving surgical efficiency and reducing preparation time. At the same time, the squeezing rod 476 can clamp the bandage to prevent the patient from wrinkling the bandage during movement; the wrinkled bandage will affect the patient's wound, and the patient will also need to move his body when the operation is over, which will cause the patient's wound to burst.

[0045] like Figure 6 , 7As shown in FIG. 8 , both ends of the transmission column 48 are helical gears. A fixed plate 481 is installed on the left side of the transmission column 48, and a transmission rod 482 is installed on the fixed plate 481.

A rotating rod 484 is installed on the right side of the transmission rod 482. One end of the spring 4841 is installed on the rotating rod 484. A fixing block 4842 is installed on the other end of the spring 4841. An adjusting rod 485 is installed above the other end of the rotating rod 484. The cross-section of the end of the adjusting rod 485 close to the driven gear 4822 is fan-shaped. A tooth block is installed on the periphery of one sector end of the section rod 485 and meshes with the driven gear 4822. A lifting block 486 is installed on the other end of the adjusting rod 485. Sliding blocks 4861 are installed on both ends of the lifting block 486. A rectangular groove 4862 is opened on the side of the lifting block 486. Two sliding blocks 4863 are installed in the rectangular groove 4862. The cross-sectional shape of the sliding block 4863 is convex. One end of the sliding block 4863 is connected to the adjusting rod 485, and the other end is connected to the adjusting rod 485. A lifting rod 487 is installed on the slider 4863, and a support tube 4871 is installed on the other end of the lifting rod 487, and the support tube 4871 passes through the adjusting rod 485. A sliding rod 488 is installed on the support tube 4871, and a limiting plate 489 is installed on the other end of the sliding rod 488. A limiting groove 4891 is provided on the limiting plate 489, and a rectangular block 4892 is installed inside the limiting groove 4891, and the rectangular block 4892 is connected to the sliding rod 488.

[0046] Both ends of the transmission column 48 are designed with helical gears, and mesh with the driven helical gear 4832 and the driven gear 4822, realizing a multi-stage transmission structure, ensuring the effective transmission of power, and improving the transmission efficiency and stability. The turbine 4821 installed on the transmission rod 482 is used in conjunction with the worm 4831 to provide efficient power transmission, while realizing one-way transmission, ensuring the stability and accuracy of the adjustment process. One end of the adjustment rod 485 is designed in a fan shape, and meshes with the driven gear 4822 through a tooth block, realizing a flexible adjustment function, which can be adjusted according to the height required for the operation, improving the flexibility and accuracy of the operation. The design of the spring 4841 enables the rotating rod 484 to automatically reset after being released, and the spring 4841 can also play a buffering role, improving work efficiency, while reducing surgical preparation and adjustment time. The design of the limiting groove 4891 and the rectangular block 4892 on the limiting plate 489 provides an effective limiting function, preventing excessive movement or misoperation during the adjustment process, ensuring the safety and reliability of the system operation. The design of the multi-stage transmission and precision adjustment structure makes the entire adjustment mechanism 4 more compact, reduces the volume and weight of the equipment, facilitates operation and movement, and saves space in the operating room. Through efficient power transmission and flexible adjustment functions, the operating bed frame can be applied to different types of breast surgery to meet the needs of different patients. The design of the convex slider 4863 and the rectangular groove 4862 reduces the friction between the components, reduces the wear and damage of the equipment, extends the service life of the equipment, and reduces maintenance costs.

[0047] like Figure 6 As shown, an arc groove 31 is opened inside the table 3, and the extrusion plate 33 can be moved in a specified direction through the arc groove 31, so that the movable extrusion plate 33 is used to adjust the distance between the extrusion plate 33 and the table 3, so that it can be suitable for the surgical conditions required by different patients. A tension spring 32 is array-clamped at one end of the left side of the arc groove 31, and the other end of the tension spring 32 is installed with the extrusion plate 33, and the extrusion plate 33 is composed of several horizontal plates 331, and connecting ropes 332 are installed between the horizontal plates 331, and the connecting ropes 332 are composed of elastic material.

[0048] The design of the arc groove 31 enables the squeezing plate 33 to move in a specified direction, thereby flexibly adjusting the distance between the squeezing plate 33 and the table 3, meeting the surgical needs of different patients and improving the adaptability of the surgery. The squeezing plate 33 can be applied to patients with different chest shapes and sizes through the moving squeezing plate 33 of the arc groove 31, enhancing the adaptability of the surgical bed frame and providing personalized surgical conditions. The squeezing plate 33 is composed of several horizontal plates 331, which are connected together by connecting ropes 332 to ensure that the squeezing plate 33 can be evenly stressed during the movement, and will not produce uneven pressure on the patient, thereby improving the patient's comfort. The connecting rope 332 is composed of elastic material and has a certain elasticity, which can effectively buffer and reduce the pressure of the squeezing plate 33 on the patient's chest, reduce discomfort, and improve the patient's comfort and safety during the operation. A tension spring 32 is connected to the array at one end of the left side of the arc groove 31, providing a stable rebound force, ensuring that the squeezing plate 33 can remain stable during the adjustment process, and will not be displaced due to external forces, thereby improving the safety and stability of the operation. The connecting rope 332 made of elastic material has good durability and can be used for a long time without being easily damaged, thereby extending the service life of the equipment. The connecting rope 332 can also be deformed by itself, thereby reducing maintenance costs.

[0049] When the patient lies on the table 3, the medical staff moves the adjusting cylinder 45 outwards. When the adjusting cylinder 45 moves outwards, the transmission block 434 on the moving plate 433 and the transmission groove of the transmission gear 412 are limited, the rotating adjusting cylinder 45 drives the limiting column 41 to rotate, thereby driving the transmission gear 412 to rotate, and the rotating transmission gear 412 drives the driven rack 47 to move leftward. The moving transmission rack squeezes the squeezing block 471 to move. When the isosceles trapezoidal block 472 is limited, the right-angle block 473 drives the squeezing rod 476 to move outwards, so that the squeezing rod 476 will not clamp the bandage. When the medical staff pulls the arm plate 462, under the action of the sliding groove 461 on the squeezing arm cylinder 46, the arm plate 462 is kept level with the table 3, and the adjusting cylinder 45 moves horizontally under the action of the adjusting spring 453 to make the limiting block 451 The arm plate 462 enters the sliding groove 461 to fix the arm plate 462, and at the same time, the inclined block 454 under the adjusting cylinder 45 squeezes the recovery block 435, and the squeezed recovery block 435 drives the recovery plate 438 to squeeze the squeezing airbag 414, and the squeezing airbag 414 transports the internal gas to the transmission airbag 415, and the transmission airbag 415 collides with the transmission bevel gear 417 to move upward, thereby engaging with the bevel gear on the rotating column. When the adjusting cylinder 45 continues to rotate, the transmission bevel gear 417 drives the rotating column to rotate, and the rotating rotating column drives the worm 4831 to rotate, and the rotating worm 4831 drives the turbine 4821 to rotate. The rotating turbine 4821 drives the adjusting rod 485 to rotate, and the rotating adjusting rod 485 drives the lifting block 486 to move upward, and the moving lifting block 486 pushes the squeezing plate 33 to move upward, thereby adjusting the patient's body, and meeting the surgical needs of different patients through the movement of the squeezing plate 33, thereby improving the surgical adaptability.
