Description

Technical Field

[0001] The present invention relates to the technical field of operating table frames, and particularly to a table frame for breast surgery. Background Art

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

[0003] Breast surgery usually requires good vision and operating space. If the chest position on the tabletop cannot be adjusted up and down, it will affect the operating angle and vision of the surgeon, thus 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 surgery. If the chest position of the tabletop cannot be raised or lowered, the patient's body position cannot be accurately adjusted, which will affect the comfort of the patient and even cause discomfort after the surgery. And during breast surgery, the doctor needs to adjust the patient's position according to the surgical requirements. If the chest position of the tabletop does not have the function of raising and lowering, it will increase the difficulty of the surgical operation and may prolong the operation time. The postoperative body position adjustment is crucial for recovery. If the chest position of the tabletop cannot be adjusted, it will affect postoperative care and the comfort of the patient. Moreover, when the doctor performs the surgery, he may need to maintain a specific posture for a long time, which will make the working posture less ideal, thus increasing fatigue and discomfort. In addition, when the patient adjusts the body on the operating table, it will cause the position of the bandage to shift and wrinkle, which will make it inconvenient to wrap the bandage finally 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 table frame for breast surgery, which solves the above technical problems. Summary of the Invention

[0005] The technical objective to be achieved by the present invention is: A table frame for breast surgery of the present invention can achieve the adjustment of the distance between the tabletop and the extrusion rod and the adjustment of the vertical distance between the extrusion plate and the tabletop through an adjustment mechanism, and can finely adjust the height of the chest bulge and the clamping force of the bandage, which can better cooperate with the surgical operation, reduce unnecessary extrusion and damage to the patient, and improve the safety of the surgery.

[0006] In order to achieve the above technical objective, the present invention provides the following technical solutions:

[0007] A bed frame for breast surgery provided by the present invention includes a base, a lifting column, a tabletop and an adjusting mechanism. It is characterized in that a lifting column is installed above the base, a tabletop is installed above the lifting column, and an adjusting mechanism is installed inside the tabletop. The adjusting mechanism drives the horizontal movement of the driven rack through the rotation of the rotating cylinder. The horizontally moving driven rack drives the vertical movement of the extrusion rod under the action of the support block, thereby adjusting the distance between the side of the tabletop and the extrusion rod, and adjusting the clamping force of the extrusion rod on the bandage by the distance between the tabletop and the extrusion rod. And convert the rotational kinetic energy of the arm cylinder into the horizontal kinetic energy of the adjusting cylinder. The horizontally kinetic energy adjusting cylinder drives the transmission bevel gear to move vertically. The vertically moving transmission bevel gear drives the lifting block to move vertically. Then the vertically moving lifting block squeezes the cross bar on the tabletop to move vertically. Then the vertically moving cross bar adjusts the vertical distance between the extrusion plate and the tabletop. Through the vertical distance, it is used to adjust the protrusion height between the chests, so as to meet the surgical needs of different patients.

[0008] Preferably, the adjusting mechanism can realize the adjustment of the distance between the tabletop and the extrusion rod and the adjustment of the vertical distance between the extrusion plate and the tabletop. This adjustment can meet the surgical needs of different patients, improve the adaptability and flexibility of the surgery. The design of the rotating cylinder and the adjusting cylinder enables precise control of the clamping force of the extrusion rod on the bandage and the protrusion height between the chests during the surgery. Precise adjustment can improve the accuracy and effect of the surgery. The adjusting mechanism realizes complex adjustments through rotation and horizontal movement, but the operation method is simple and easy for doctors to make quick adjustments during the surgery, reducing the surgical preparation time and the adjustment time during the surgery. Through the fine adjustment of the chest protrusion height and the bandage clamping force, it can better cooperate with the surgical operation, reduce unnecessary squeezing and damage to the patient, and improve the safety of the surgery. The adjustable design enables the bed frame to be applicable to 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 surgical preparation and adjustment time, and improving the overall surgical efficiency.

[0009] The adjusting mechanism includes a limit post, a rotating cylinder, a limit cylinder, a fixed cylinder, an adjusting cylinder, an arm cylinder, a driven rack and a transmission post. A limit post is installed on the side of the tabletop. A rotating cylinder is installed on the limit post. A limit cylinder is installed on the side of the rotating cylinder. Fixed cylinders are installed in an array on the side of the limit cylinder. A limit groove is formed inside the fixed cylinder. An adjusting groove is formed in the middle fixed cylinder. An adjusting cylinder is installed at the central position of the fixed cylinder. Arm cylinders are installed in an array on the adjusting cylinder, and the fixed cylinders and the arm cylinders are arranged at intervals. The arrangement of the fixed cylinders and the arm cylinders at intervals can evenly cover the gravity of the arm plate on the adjusting cylinder, thereby increasing the stability of the arm plate. A driven rack is installed above the limit post. A transmission post is installed below the limit post.

[0010] Preferably, the design of arranging the fixed cylinders and the arm cylinders at intervals can evenly distribute the gravity of the arm plate, improve the stability of the arm plate, thereby increasing the stability of the entire operating bed frame and ensuring safety during the operation. The design of the limit post, the limit cylinder and the limit groove provides multiple limit protections, avoiding excessive adjustment or misoperation during the adjustment process, and ensuring the safety and reliability of the adjustment process. Through the design of the rotating cylinder and the adjusting cylinder, the operation is made more convenient, enabling medical staff to easily achieve adjustment, reducing the operation preparation and adjustment time, and improving work efficiency. By precisely adjusting the distance between the tabletop and the pressing plate, personalized adjustment can be carried out according to the specific conditions of the patient, improving the comfort of the patient during the operation, reducing unnecessary compression and pain, and enabling the operating bed frame to be applicable to patients with different body types and surgical needs, with strong adaptability and expanding its application range. 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 surgical risk.

[0011] An annular groove is formed in the limit post above the rotating cylinder. 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. Transmission grooves are formed in an array on the lower surface of the transmission gear. The array of transmission grooves is engaged with transmission blocks, thereby increasing the friction between the moving plate and the transmission gear. Then, the transmission gear is driven to rotate through the friction force. The rotating transmission gear drives the driven rack to move horizontally. An extrusion airbag is installed on the limit post below the rotating cylinder. A transmission airbag is installed below the extrusion airbag. A flow groove is formed in the limit post between the extrusion airbag and the transmission airbag. The gas between the extrusion airbag and the transmission airbag is transmitted through the flow groove on the limit post. By squeezing the extrusion airbag with a recovery plate, the gas inside the extrusion airbag enters the transmission airbag through the flow groove and expands. The expanded transmission airbag drives a transmission bevel gear to move vertically. The vertically moving transmission bevel gear meshes with the bevel gear on the transmission post. A transmission bevel gear is installed above the transmission airbag. The side of the transmission bevel gear with teeth faces upward.

[0012] Preferably, by providing an annular groove on the limit post above the rotating cylinder, the vertical height of the transmission gear is limited to prevent unnecessary movement of the transmission gear, thereby improving the stability of the transmission. The transmission grooves arrayed on the lower surface of the transmission gear increase the friction between the moving plate and the transmission gear, and the rotation of the transmission gear is driven by this friction force, ensuring the effectiveness and smoothness of the transmission. The extrusion airbag and the transmission airbag are connected through the flow groove on the limit post, and the linkage between the airbags is realized by gas transmission. This design can precisely control the inflation and deflation of the airbag during the operation, and then realize the vertical movement of the transmission bevel gear, 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. The inflation of the transmission airbag drives the vertical movement of the transmission bevel gear, realizing the automatic 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 design of the transmission bevel gear makes one side of the gear face upward, which is more conducive to meshing with the bevel gear on the transmission column, providing stable power transmission and ensuring the smoothness of the adjustment action.

[0013] A moving block is installed above the interior of the limit cylinder. The cross-sectional shape of the moving block is trapezoidal. A moving cylinder is installed above the trapezoidal moving block. A moving plate is installed on the moving cylinder, and the moving plate is also located below the transmission gear. Transmission blocks are arrayed and installed on the moving plate, and the positions of the transmission blocks correspond one by one to the transmission grooves. A recovery block is installed below the interior of the limit cylinder. A recovery cylinder is installed on the recovery block. A recovery spring is installed on the side of the recovery cylinder, and the recovery spring is located between the inner wall of the limit cylinder and the recovery block. The other end of the recovery cylinder is installed with a recovery plate, and the recovery plate is located above the extrusion airbag.

[0014] Preferably, the trapezoidal design of the moving block and the one-to-one correspondence between the transmission block and the transmission groove on the moving plate ensure the accuracy and stability of the transmission process and improve the accuracy of the adjustment. The recovery spring provides a stable elastic force, so that the recovery block and the recovery plate can quickly return to the initial position, improving the response speed and efficiency of the adjustment device. 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.

[0015] The adjusting cylinder is provided with a limit block in an array, and the limit block is located in the adjusting groove. The adjusting cylinder is provided with an extrusion ring in an array, and the extrusion ring is located inside the adjusting groove. An adjusting spring is clamped on the side of the extrusion ring, and the other end of the adjusting spring is clamped on the fixed cylinder. Two tilting blocks are installed on the side of the adjusting cylinder close to the rotating cylinder, and the tilting blocks are located on the side of the center line of the adjusting cylinder, and the inclined surfaces of the two tilting blocks are arranged face to face.

[0016] Preferably, a limit block is installed in the adjustment groove to effectively limit the movement of the adjustment tube, preventing the adjustment tube from excessive movement or position displacement, thereby improving the stability and reliability of the adjustment process. The extrusion ring is installed inside the adjustment groove and connected to the fixed tube through an adjustment spring, so that the pressure during 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 can automatically reset the extrusion ring, which simplifies the operation process, reduces the surgical preparation and adjustment time, and improves work efficiency. The design of the limit block and the adjustment spring 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 and the adjustment spring makes the entire adjustment mechanism more compact, reduces the size and weight of the equipment, and is easy to operate and move. The design of the adjustment spring and the limit block reduces the wear and damage of the adjustment mechanism, extends the service life of the equipment, and reduces maintenance costs.

[0017] 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.

[0018] Preferably, the depth of the sliding groove gradually becomes shallower from bottom to top, making the adjustment process more precise, capable of fine-tuning according to actual needs, improving the accuracy and precision of adjustment, and meeting the surgical needs of different patients. One end below the sliding groove has a cliff-like design with a sudden increase in depth, providing an effective limiting function to prevent the arm cylinder from moving excessively or detaching during sliding, ensuring the stability and safety of the adjustment process. The adjustment of the arm cylinder is achieved through the sliding groove, with simple and intuitive operation. Medical staff can easily make adjustments, reducing the surgical preparation and adjustment time and improving surgical efficiency. The arm plate is installed on the side of the arm cylinder. Through the design of the sliding groove, multi-angle adjustment of the arm plate can be achieved to meet the needs of different surgical positions, improving the flexibility and adaptability of the surgery. The design of the sliding groove reduces the friction between the arm cylinder and other components, reduces equipment wear and damage, extends the service life of the equipment, and reduces maintenance costs. It can be adjusted individually according to the patient's body shape and surgical needs, reducing the pressure and discomfort on the patient and enhancing the patient's comfort during the surgery. The design of the sliding groove and the arm plate makes the adjustment mechanism more compact, reduces the volume and weight of the equipment, facilitates operation and movement, and saves operating room space. The cliff-like design with a sudden increase in depth provides additional limiting protection to prevent the arm cylinder from accidentally detaching during sliding, increasing the safety and reliability of the operation.

An isosceles trapezoidal groove is formed on the inclined surface of the right trapezoidal block. Support blocks are installed on the upper and lower surfaces of the right trapezoidal block, and an extrusion rod is installed on the left side of the right trapezoidal block.

[0020] Preferably, the driven rack engages with the driving gear, ensuring the efficiency and stability of the transmission process. The L-shaped design of the driven rack enables it to better transmit power and improve the transmission efficiency of the entire system. The L-shaped design of the driven rack allows it to be compactly arranged at the inner end of the driving gear, saving space and making the overall structure more compact, suitable for use in limited spaces such as operating rooms. The extrusion block is designed as a right trapezoid, and an isosceles trapezoid block and a right-angle block are installed on its inclined surface, capable of providing extrusion functions at multiple angles and in multiple directions. An isosceles trapezoid groove is provided on the inclined surface of the right trapezoid block, enabling the right trapezoid block to be accurately positioned, ensuring the stability and accuracy of the extrusion block during use and reducing the possibility of misoperation. Support blocks are installed on the upper and lower surfaces of the right trapezoid block, providing additional support force, improving the stability and load-bearing capacity of the entire clamping, and ensuring stable operation during the operation. The extrusion rod is installed on the left side of the right trapezoid block. By adjusting the extrusion rod, precise control of the extrusion force can be achieved, ensuring appropriate extrusion of the patient's chest, enhancing the comfort and safety of the patient. Through the reasonable design of the driven rack, extrusion block, isosceles trapezoid block, and right-angle block, etc., the entire adjustment operation becomes more convenient. Medical staff can easily perform the adjustment, improving the surgical efficiency and reducing the preparation time. At the same time, the extrusion rod can clamp the bandage to prevent the bandage from wrinkling during the patient's movement; wrinkled bandages can affect the patient's wound, and when the operation ends, the patient also needs to move, which may cause the patient's wound to burst.

[0021] Both ends of the transmission column are helical gears. A fixing plate is installed on the left side of the transmission column. A transmission rod is installed on the fixing plate.

A limiting plate is installed at the other end of the sliding rod. A limiting groove is provided on the limiting plate. A rectangular block is installed inside the limiting groove. The rectangular block is connected to the sliding rod.

[0022] Preferably, both ends of the transmission column are designed as helical gears and mesh with the driven helical gear and the driven gear, realizing a multi-stage transmission structure, ensuring the effective transmission of power, and improving the transmission efficiency and stability. The turbine installed on the transmission rod is used in cooperation with the worm, providing efficient power transmission and realizing one-way transmission at the same time, ensuring the smoothness and accuracy of the adjustment process. One end of the adjustment rod is designed as a sector and meshes with the driven gear through a tooth block, realizing a flexible adjustment function, capable of adjusting according to the height required for the operation, and improving the flexibility and accuracy of the operation. The design of the spring enables the rotating rod to automatically reset after being released, and the spring can also play a buffering role, improving the work efficiency and reducing the operation preparation and adjustment time. The design of the limiting groove and the rectangular block on the limiting plate 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 the precision adjustment structure makes the entire adjustment mechanism more compact, reducing the volume and weight of the equipment, facilitating operation and movement, and saving the operating room space. Through efficient power transmission and flexible adjustment functions, the operating table frame can be applied to different types of breast surgery, meeting the needs of different patients. The design of the convex slider and the rectangular groove reduces the friction between components, reduces the wear and damage of the equipment, extends the service life of the equipment, and reduces the maintenance cost.

[0023] An arc-shaped groove is provided inside the tabletop. Through the arc-shaped groove, the pressing plate can move in a specified direction, so that the moving pressing plate is used to adjust the distance between the pressing plate and the tabletop, so as to be applicable to the surgical conditions required by different patients.

[0041] Such as Figure 1As shown in the figure, a bed frame for breast surgery provided by the present invention includes a base 1, a lifting column 2, a tabletop 3 and an adjustment mechanism 4. It is characterized in that a lifting column 2 is installed above the base 1, a tabletop 3 is installed above the lifting column 2, an adjustment mechanism 4 is installed inside the tabletop 3. The adjustment mechanism 4 drives the horizontal movement of the driven rack 47 through the rotation of the rotating cylinder 42. The horizontally moving driven rack 47 drives the vertical movement of the extrusion rod 476 under the action of the support block 475, so as to adjust the distance between the side surface of the tabletop 3 and the extrusion rod 476, and adjust the clamping force of the extrusion rod 476 on the bandage through the distance between the tabletop 3 and the extrusion rod 476; and converts the rotational kinetic energy of the arm cylinder 46 into the horizontal kinetic energy of the adjustment cylinder 45. The horizontally moving adjustment cylinder 45 drives the transmission bevel gear 417 to move vertically. The vertically moving transmission bevel gear 417 drives the lifting block 486 to move vertically. Then the vertically moving lifting block 486 squeezes the cross bar on the tabletop 3 to move vertically. Then the vertically moving cross bar adjusts the vertical distance between the pressing plate 33 and the tabletop 3. Through the vertical distance, it is used to adjust the convex height between the chests, so as to meet the surgical needs of different patients.

[0042] Through the adjustment mechanism 4, the distance adjustment between the tabletop 3 and the extrusion rod 476 and the vertical distance adjustment between the pressing plate 33 and the tabletop 3 can be realized; this adjustment can meet the surgical needs of different patients, improve the adaptability and flexibility of the surgery. The designs of the rotating cylinder 42 and the adjustment cylinder 45 enable the accurate control of the clamping force of the extrusion rod 476 on the bandage and the convex height between the chests during the surgical process. Precise adjustment can improve the accuracy and effect of the surgery. The adjustment mechanism 4 realizes complex adjustments through rotation and horizontal movement, but the operation method is simple and easy for doctors to make quick adjustments during the surgery, reducing the surgical preparation time and the adjustment time during the surgery. Through the fine adjustment of the chest convex height and the bandage clamping force, it can better cooperate with the surgical operation, reduce unnecessary squeezing and damage to the patient, and improve the safety of the surgery. The adjustable design makes the bed frame applicable to 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 surgical preparation and adjustment time and improving the overall surgical efficiency.

The limit post 41 is installed on the side of the tabletop 3. The rotating cylinder 42 is installed on the limit post 41. The limit cylinder 43 is installed on the side of the rotating cylinder 42. The fixed cylinders 44 are arranged in an array on the side of the limit cylinder 43. A limit groove 441 is formed inside the fixed cylinder 44, and an adjusting groove 442 is formed in the middle fixed cylinder 44. The adjusting cylinder 45 is installed at the central position of the fixed cylinder 44. The arm cylinders 46 are arranged in an array on the adjusting cylinder 45, and the fixed cylinders 44 and the arm cylinders 46 are arranged at intervals. The arrangement of the fixed cylinders 44 and the arm cylinders 46 at intervals can evenly cover the gravity of the arm plate 462 on the adjusting cylinder 45, thereby increasing the stability of the arm plate 462. The driven rack 47 is installed above the limit post 41, and the transmission post 48 is installed below the limit post 41.

[0044] Through the design of arranging the fixed cylinders 44 and the arm cylinders 46 at intervals, the gravity of the arm plate 462 can be evenly distributed, improving the stability of the arm plate 462, thereby increasing the stability of the entire operating bed frame and ensuring safety during the operation. The designs of the limit post 41, the limit cylinder 43 and the limit groove 441 provide multiple limit protections, avoiding over-adjustment or misoperation during the adjustment process, and ensuring the safety and reliability of the adjustment process. Through the designs of the rotating cylinder 42 and the adjusting cylinder 45, the operation is made more convenient, enabling medical staff to easily achieve adjustment, reducing the operation preparation and adjustment time, and improving work efficiency. By precisely adjusting the distance between the tabletop 3 and the pressing plate 33, personalized adjustment can be carried out according to the specific situation of the patient, improving the comfort of the patient during the operation, reducing unnecessary compression and pain, and enabling the operating bed frame to be applicable to patients with different body types and surgical requirements, having strong adaptability and expanding its application range. By precisely adjusting the operating bed frame, it can better cooperate with the surgical operation, improve the success rate and effect of the operation, and reduce the surgical risk.

[0045] As Figure 3 and 4As shown in the figure, an annular groove 411 is formed on the limiting post 41 above the rotating cylinder 42. 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. Transmission grooves 413 are arrayed on the lower surface of the transmission gear 412. The arrayed transmission grooves 413 are engaged with the transmission blocks 434, thereby increasing the friction between the moving plate 433 and the transmission gear 412. Then, the transmission gear 412 is driven to rotate by the friction force. The rotating transmission gear drives the driven rack 47 to move horizontally. An extrusion airbag 414 is installed on the limiting post 41 below the rotating cylinder 42. A transmission airbag 415 is installed below the extrusion airbag 414. A flow groove 416 is formed on the limiting post 41 between the extrusion airbag 414 and the transmission airbag 415. The gas between the extrusion airbag 414 and the transmission airbag 415 is transmitted through the flow groove 416 on the limiting post 41. The extrusion airbag 414 is extruded by the recovery plate 438, and the gas inside the extrusion airbag 414 enters the transmission airbag 415 through the flow groove 416 and expands. The expanded transmission airbag 415 drives the transmission helical gear 417 to move vertically. The vertically moving transmission helical gear 417 meshes with the helical gear on the transmission column 48. The transmission helical gear 417 is installed above the transmission airbag 415, and the side of the transmission helical gear 417 with teeth faces upward.

[0046] By setting the annular groove 411 on the limiting post 41 above the rotating cylinder 42, the vertical height of the transmission gear 412 is limited to prevent unnecessary movement of the transmission gear 412, thereby improving the stability of the transmission. The transmission grooves 413 arrayed on the lower surface of the transmission gear 412 increase the friction between the moving plate 433 and the transmission gear 412. The rotation of the transmission gear 412 is driven by this friction force, ensuring the effectiveness and smoothness of the transmission. The extrusion airbag 414 and the transmission airbag 415 are connected through the flow groove 416 on the limiting post 41, and the linkage between the airbags is realized by gas transmission. This design can accurately control the inflation and deflation of the airbags during the operation, and then realize the vertical movement of the transmission helical gear 417, 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. The inflation of the transmission airbag 415 drives the transmission helical gear 417 to move vertically, realizing an automatic adjustment function and reducing the complexity and error of manual operation. The transmission helical gear 417 meshes with the helical gear on the transmission column 48, realizing 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 helical gear 417 makes the side with teeth face upward, which is more conducive to meshing with the helical gear on the transmission column 48, providing stable power transmission and ensuring the smoothness of the adjustment action.

[0047] As Figure 2 and 3 shown, a moving block 431 is installed above the interior of the limiting cylinder 43. The cross-sectional shape of the moving block 431 is trapezoidal. Above the trapezoidal moving block 431, a moving cylinder 432 is installed. 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 arrayed on the moving plate 433, and the positions of the transmission blocks 434 correspond one by one to the transmission grooves 413. A restoring block 435 is installed below the interior of the limiting cylinder 43. A restoring cylinder 436 is installed on the restoring block 435. A restoring spring 437 is installed on the side of the restoring cylinder 436, and the restoring spring 437 is located between the inner wall of the limiting cylinder 43 and the restoring block 435. The other end of the restoring cylinder 436 is installed with a restoring plate 438, and the restoring plate 438 is located above the extrusion airbag 414.

[0048] The trapezoidal design of the moving block 431 and the one-to-one correspondence between the transmission blocks 434 on the moving plate 433 and the transmission grooves 413 ensure the accuracy and stability of the transmission process and improve the adjustment accuracy. The restoring spring 437 provides a stable elastic force, enabling the restoring block 435 and the restoring plate 438 to quickly return to their initial positions, improving the response speed and efficiency of the adjustment device. The restoring spring 437 is located between the inner wall of the limiting cylinder 43 and the restoring block 435. Through the elastic force, it ensures the safety and stability of the transmission system during use, avoiding system failure caused by operation errors or unexpected situations. The cooperation between the extrusion airbag 414 and the restoring plate 438 enhances the comfort and safety of the patient during the operation. The limiting cylinder 43 provides multiple limiting protections, preventing excessive movement or misoperation of the transmission components during adjustment and ensuring the safe and reliable operation of the entire system. The one-to-one correspondence between the positions of the transmission blocks 434 and the transmission grooves 413 increases the friction between the moving plate 433 and the transmission gear 412, ensuring the stability and reliability during the transmission process and enhancing the overall transmission efficiency. The restoring block 435 and the restoring plate 438 can quickly return to the initial state after the operation stops, facilitating the next operation and improving the work efficiency and the reliability of the system.

[0049] As Figure 3 shown, limiting blocks 451 are arrayed on the adjusting cylinder 45. The limiting blocks 451 are located within the adjusting grooves 442. Extrusion rings 452 are arrayed on the adjusting cylinder 45, and the extrusion rings 452 are located inside the adjusting grooves 442. An adjusting spring 453 is clamped on the side of the extrusion ring 452, and the other end of the adjusting spring 453 is clamped on the fixed cylinder 44. Two inclined blocks 454 are installed on one side of the adjusting cylinder 45 close to the rotating cylinder 42, and the inclined blocks 454 are located on the side of the center line of the adjusting cylinder 45. The inclined surfaces of the two inclined blocks 454 are arranged face to face.

[0050] The limit block 451 is installed in the adjustment groove 442 to effectively limit the movement of the adjustment cylinder 45, preventing the adjustment cylinder 45 from moving excessively or shifting in position, 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 cylinder 44 through the adjustment spring 453, enabling the pressure during the adjustment process to be precisely controlled, ensuring the accuracy and stability of the adjustment operation, and meeting different surgical requirements. 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 more convenient. Medical staff can easily perform the adjustment, reducing the operation difficulty and improving the surgical efficiency. The design of the extrusion ring 452 and the adjustment spring 453 makes the entire adjustment mechanism 4 more compact, reducing the volume and weight of the device, and facilitating operation and movement. 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 device, and reduces the maintenance cost.

[0051] As Figure 2 , 3 shown in Figures 3 and 4, a sliding groove 461 is formed in the arm cylinder 46. The depth of the sliding groove 461 gradually becomes shallower from bottom to top, and the lower end of the sliding groove 461 has a cliff-like deepening. An arm plate 462 is installed on the side of the arm cylinder 46.

[0052] The design that the depth of the sliding groove 461 gradually becomes shallower from bottom to top makes the adjustment process more precise, enabling fine-tuning according to actual needs, improving the accuracy and precision of adjustment, and meeting the surgical needs of different patients. One end below the sliding groove 461 has a cliff-like design with a deeper depth, providing an effective limiting function to prevent the arm cylinder 46 from moving excessively or detaching during sliding, ensuring the stability and safety of the adjustment process. The adjustment of the arm cylinder 46 is achieved through the sliding groove 461, and the operation is simple and intuitive. Medical staff can easily make adjustments, reducing the surgical preparation and adjustment time and improving surgical efficiency. The arm plate 462 is installed on the side of the arm cylinder 46. Through the design of the sliding groove 461, multi-angle adjustment of the arm plate 462 can be achieved, meeting the needs of different surgical positions and improving the flexibility and adaptability of the surgery. The design of the sliding groove 461 reduces the friction between the arm cylinder 46 and other components, reduces equipment wear and damage, extends the service life of the equipment, and reduces maintenance costs. It can be adjusted individually according to the patient's body shape and surgical needs, reducing the pressure and discomfort on the patient and enhancing the comfort of the patient during the surgery. The design of the sliding groove 461 and the arm plate 462 makes the adjustment mechanism 4 more compact, reduces the volume and weight of the equipment, facilitates operation and movement, saves operating room space. The cliff-like design with a deeper depth provides additional limiting protection to prevent the arm cylinder 46 from accidentally detaching during sliding, increasing the safety and reliability of the operation.

Support blocks 475 are installed on the upper and lower surfaces of the right trapezoidal block. A pressing rod 476 is installed on the left side of the right trapezoidal block.

[0054] The driven rack 47 meshes with the transmission gear 412, ensuring the efficiency and stability of the transmission process. The L-shaped design of the driven rack 47 enables it to better transmit power, improving the transmission efficiency of the entire system. The L-shaped design of the driven rack 47 allows it to be compactly arranged at the inner end of the transmission gear 412, saving space and making the overall structure more compact, suitable for use in limited spaces such as operating rooms. The extrusion block 471 is designed as a right-angled trapezoid, and an isosceles trapezoid block 472 and a right-angled block 473 are installed on its inclined surface, capable of providing extrusion functions at multiple angles and in multiple directions. An isosceles trapezoid groove 474 is provided on the inclined surface of the right-angled trapezoid block, enabling the right-angled trapezoid block to 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 trapezoid block, providing additional support force, improving the stability and load-bearing capacity of the entire clamping, and ensuring stable operation during the operation. The extrusion rod 476 is installed on the left side of the right-angled trapezoid block. By adjusting the extrusion rod 476, precise control of the extrusion force can be achieved, ensuring appropriate extrusion of the patient's chest and enhancing the comfort and safety of the patient. Through the reasonable design of the driven rack 47, the extrusion block 471, the isosceles trapezoid block 472, the right-angled block 473, etc., the entire adjustment operation is made more convenient, and medical staff can easily perform the adjustment, improving the surgical efficiency and reducing the preparation time. At the same time, the extrusion rod 476 can clamp the bandage to prevent wrinkles from occurring on the bandage when the patient moves; wrinkled bandages can affect the patient's wound, and when the operation ends, the patient needs to move their body, which may cause the patient's wound to burst.

[0055] Such as Figure 6 , 7As shown in FIGS. 7 and 8, both ends of the transmission column 48 are bevel gears. A fixing plate 481 is installed on the left side of the transmission column 48.

The other end of the spring 4841 is installed with a fixing block 4842. An adjusting rod 485 is installed above the other end of the rotating rod 484. The cross-sectional shape of one end of the adjusting rod 485 close to the driven gear 4822 is fan-shaped.

[0056] Both ends of the transmission column 48 are designed as helical gears, which 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 cooperation with the worm 4831 to provide efficient power transmission, and at the same time realizes one-way transmission, ensuring the smoothness and accuracy of the adjustment process. One end of the adjustment rod 485 is designed as a sector 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 by the operation, improving the flexibility and accuracy of the operation. The design of the clock spring 4841 enables the rotating rod 484 to automatically reset after being released, and the clock spring 4841 can also play a buffering role, improving the work efficiency and reducing the operation preparation and adjustment time. The design of the limit groove 4891 and the rectangular block 4892 on the limit 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 precise adjustment structure makes the entire adjustment mechanism 4 more compact, reducing the volume and weight of the equipment, facilitating operation and movement, and saving the operating room space. Through efficient power transmission and flexible adjustment functions, the operating bed frame can be applied to different types of breast surgery, meeting the needs of different patients.

[0057] As Figure 6 shown, an arc groove 31 is opened inside the tabletop 3. Through the arc groove 31, the extrusion plate 33 can be moved in a specified direction, so that the moving extrusion plate 33 is used to adjust the distance between the extrusion plate 33 and the tabletop 3, so as to be applicable to the surgical conditions required by different patients. One end of the left side of the arc groove 31 is arrayed and clamped with a tension spring 32. The other end of the tension spring 32 is provided with an extrusion plate 33. The extrusion plate 33 is composed of several cross plates 331, and a connecting rope 332 is installed between the cross plates 331. The connecting rope 332 is made of an elastic material.

[0058] The design of the arc-shaped groove 31 enables the extrusion plate 33 to move in a specified direction, thereby flexibly adjusting the distance between the extrusion plate 33 and the tabletop 3 to meet the surgical needs of different patients and improving surgical adaptability. By moving the extrusion plate 33 through the arc-shaped groove 31, it can be applied to patients with different chest shapes and sizes, enhancing the adaptability of the operating bed frame and providing personalized surgical conditions. The extrusion plate 33 is composed of several cross plates 331, which are connected together by connecting ropes 332 to ensure that the extrusion plate 33 can be evenly stressed during movement and will not cause uneven pressure on the patient, improving the comfort of the patient. The connecting ropes 332 are made of elastic materials and have a certain elasticity, which can effectively buffer and reduce the pressure of the extrusion plate 33 on the patient's chest, reduce discomfort, and improve the comfort and safety of the patient during the operation. One end of the left side of the arc-shaped groove 31 is arrayed and clamped with a tension spring 32, providing a stable resilience force to ensure that the extrusion plate 33 can remain stable during adjustment and will not be displaced due to external forces, improving the safety and stability of the operation. The connecting ropes 332 made of elastic materials have good durability and can be used for a long time without being easily damaged, extending the service life of the equipment, and can also deform themselves, reducing the maintenance cost.

[0059] 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.
