[0002] With the continuous development of medical technology and modern science and technology, the use of surgical robots to perform surgical procedures has been widely adopted by many hospitals. Surgery requires the robot to have high precision, positioning flexibility and operational stability. Therefore, the operating trolley needs to have high stability to ensure the smooth progress of the operation. As an important mechanism of the surgical robot, the stability of the operating trolley is crucial. The legs of the operating trolley support and stabilize the operating trolley. Therefore, whether the legs of the operating trolley are stable directly determines the overall stability of the operating trolley and the precision of the surgical robot.

[0003] In the prior art, the surgical trolley is mostly fixed simply by the brakes of the casters.

It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present application and are not used to limit the embodiments of the present application.

[0033] As the patient end of the surgical robot, the operating table can perform operations such as patient examination and surgical treatment. It has high precision, a short learning curve, and reduces the labor intensity of medical staff. Operating tables are usually heavy and need to be moved by casters in actual use. Fixed operating tables use brake structures to limit the casters so that they cannot move. This type of fixing method has the problem of poor stability.

[0034] The embodiment of the present application provides a liftable surgical trolley, the support legs of which can be lifted and lowered and provide stable support with the ground, so as to solve the problem in the prior art that the surgical trolley is simply fixed by brakes on casters, which poses a great risk of instability.

[0035] like Figure 1-4The figure shows a schematic diagram of the structure of the vehicle floor and the lifting device of the liftable surgical trolley provided in this embodiment in different states and at different angles. The liftable surgical trolley includes a lifting device, which includes a leg assembly 4, a support link assembly and a lifting assembly 7; the leg assembly 4 includes a fixed sleeve 41 and a lifting leg 42; the fixed sleeve 41 is connected to the vehicle floor 10, and the lifting leg 42 is connected to the fixed sleeve 41 in a liftable and movable manner; the support link assembly is rotatably connected to the vehicle floor 10 and the lifting leg 42 respectively, and the support link assembly includes an unfolded state and a folded state. In the unfolded state, the lifting leg 42 moves downward to support the ground; the lifting assembly 7 is connected to the support link assembly, and is used to drive the support link assembly to the folded state to drive the lifting leg 42 to move upward.

[0036] In the embodiment of the present application, the fixed sleeve 41 is a hollow tubular structure, and the lifting leg 42 is disposed in the fixed sleeve 41 and is slidably connected to the fixed sleeve 41. In some embodiments, a support pad 43 is provided at the bottom of the lifting leg 42. The support pad 43 can be an elastic pad made of materials including but not limited to rubber / polyurethane.

[0037] The supporting connecting rod assembly comprises a first supporting assembly, and the first supporting assembly comprises a first connecting rod assembly 1 and a connecting shaft 3, such as Figure 5 As shown, the first connecting rod assembly 1 includes a supporting footrest 11 and a middle connecting rod 12. One end of the supporting footrest 11 is rotatably connected to the vehicle floor 10, and the other end of the supporting footrest 11 is rotatably connected to the middle connecting rod 12; the middle connecting rod 12 is connected to the connecting shaft 3, and the connecting shaft 3 is connected to one end of the lifting leg 42 away from the vehicle floor 10. The relative rotation between the supporting footrest 11 and the middle connecting rod 12 enables the supporting connecting rod assembly to switch between the unfolded state and the folded state.

[0038] Specifically, in the embodiment of the present application, the supporting footrest member 11 includes a footrest link 111 and a pedal link 112 , and a supporting link shaft 14 is provided at one end where the footrest link 111 is connected to the pedal link 112 , and the supporting footrest member 11 is rotatably connected to the vehicle floor 10 via the supporting link shaft 14 .

[0039] In the embodiment of the present application, the pedal link 111 and the pedal link 112 are integrally formed. A pedal 113 is provided at one end of the pedal link 112 away from the pedal link 11. The pedal link 11 and the pedal link 112 are connected in an L shape, and the length of the pedal link 112 is greater than that of the pedal link 111, so that the pedal link 111 can be driven to rotate more effortlessly through the pedal link 112. In some embodiments, the pedal 113 can be fixed to the pedal link 112 by means of, but not limited to, snap connection, fastening connection or bonding, and the width of the pedal 113 is greater than that of the pedal link 112, so as to facilitate foot pedaling and force application.

[0040] In some embodiments, the supporting link shaft 14 is connected to the vehicle floor 10 via a shaft connection seat.

[0041] Specifically, a lifting connection shaft 15 is provided between the pedal connecting rod 111 and the middle connecting rod 12 , and the pedal connecting rod 111 is rotatably connected to the middle connecting rod 12 via the lifting connection shaft 15 .

[0042] Through the above arrangement, the operator steps on the pedal 113, the pedal connecting rod 112 rotates downward relative to the vehicle floor 10, the originally folded pedal connecting rod 111 and the middle connecting rod 12 rotate relative to each other and become unfolded, the middle connecting rod 12 rotates downward, pushing the connecting shaft 3 to move downward, thereby driving the lifting leg 42 to move downward, when the lifting leg 42 moves down to the bottom and touches the ground, it will move further downward, thereby pushing the entire trolley to rise, so that the casters of the trolley leave the ground, thereby providing stable support for the trolley. It is understandable that the lifting leg 42 can also move down to just touch the ground, at which time the weight of the operating trolley is supported by the lifting leg 42 and the casters, and due to the static friction between the lifting leg 42 and the ground, the operating trolley remains fixed. During the downward movement of the lifting leg 42, the fixed sleeve 41 provides guidance for it, so that the lifting leg 42 can move straight up and down, ensuring the stability of the operating trolley during the lifting process.

[0043] Specifically, when the pedal link 112 rotates downward to the maximum angle relative to the vehicle floor 10, the pedal link 111 drives the middle link 12 to rotate to a final position that passes the position where the pedal link 111 and the middle link 12 are in line. In this embodiment, the pedal link 111 rotates clockwise, driving the middle link 12 to rotate counterclockwise, and when the pedal link 111 and the middle link 12 are in a straight line, the dead point position is reached. At this time, the pedal link 111 continues to drive the middle link 12 to rotate to a position slightly beyond the dead point, which can increase the thrust on the connecting shaft 3, improve the support reliability of the lifting leg 42, and at the same time, the structure is simple.

[0044] Specifically, the vehicle floor 10 is provided with a support stopper 6. When the pedal link 112 rotates downward to the maximum angle relative to the vehicle floor 10, the support stopper 6 contacts the pedal link 111, and the rotation of the support pedal 11 is limited. In some embodiments, the support stopper 6 includes a fixed seat connected to the vehicle floor 10 and a limit block for contacting the pedal link 111, and the limit block is connected to the fixed seat. In the embodiment of the present application, the support stopper 6 is arranged on one side of the pedal link 111 to prevent the pedal link 111 from continuing to rotate after driving the middle link 12 to rotate slightly beyond the dead point.

[0045] Specifically, a lifting stopper 8 is provided between the pedal connecting rod 112 of the support pedal member 11 and the vehicle floor 10. When the pedal connecting rod 112 rotates upward to the maximum angle relative to the vehicle floor 10, the lifting stopper 8 contacts the pedal connecting rod 112 to limit the position of the support pedal member 11. The support stopper 6 and the lifting stopper 8 of the present application jointly limit the rotation range of the support pedal member 11.

[0046] In the embodiment of the present application, the support link assembly of the liftable surgical trolley includes a first support assembly, a second support assembly with the same structure as the first support assembly, and a long link 5. The first support assembly and the second support assembly are respectively arranged at the two ends of the vehicle bottom plate 10, and the two ends of the long link 5 are respectively connected to the first support assembly and the second support assembly through a lifting connecting shaft 15. The first support assembly includes a first link assembly 1, a second link assembly 2 with the same structure as the first link assembly 1, and a connecting shaft 3. The two ends of the connecting shaft 3 are respectively connected to the lifting legs 42 of the two leg assemblies 4, and can drive the lifting legs 42 at both ends to rise and fall synchronously. In actual application, by stepping on the pedal 113, the pedal link 111 is driven to rotate, thereby driving the middle link 12 to rotate and move downward, and the middle link 12 pushes the connecting shaft 13 to move downward, thereby driving the lifting legs 42 to move downward. The lifting legs 42 move downward to support the entire surgical trolley to rise, so that the casters leave the ground. The first connecting rod assembly 1 and the second connecting rod assembly 2 of the first supporting assembly are connected via a lifting connecting shaft 15; the first supporting assembly and the second supporting assembly are connected via a long connecting rod 5, and both ends of the long connecting rod 5 are respectively connected to the corresponding lifting connecting shafts 15. When the pedal connecting rod 111 and the middle connecting rod 12 in the first supporting assembly are changed from folded to unfolded, the lifting connecting shaft 15 moves to one side, driving the long connecting rod 5 to move, thereby pushing the lifting connecting shaft 15 of the second supporting assembly to move, so that the pedal connecting rod 111 and the middle connecting rod 12 of the second supporting assembly are unfolded, and the connecting shaft 13 and the lifting legs 42 move downward synchronously. Since the first supporting assembly and the second supporting assembly have the same structure and size, their multiple lifting legs 42 can be lifted and lowered synchronously.

[0047] Specifically, Figure 6 As shown, the lifting assembly 7 includes a lifting pedal driving member 71 and a gear transmission group 72 for connecting with the supporting footrest member 11, and the gear transmission group 72 is configured to enable the supporting footrest member 11 and the lifting pedal driving member 71 to rotate simultaneously in opposite rotation directions. In some embodiments, a lifting pedal 711 is provided on the lifting pedal driving member 71. In actual application, the lifting pedal driving member 71 is rotated by stepping on the lifting pedal 711, which has a simple structure and is convenient for lifting operation.

[0048] In the embodiment of the present application, the gear transmission group 72 includes a first transmission gear 721 and a second transmission gear 722 meshing with the first transmission gear 721, the first transmission gear 721 is connected to the lifting connecting rod shaft 73, and the second transmission gear 722 is connected to the supporting footrest member 11 through the supporting connecting rod shaft 14. Since the first transmission gear 721 and the second transmission gear 722 rotate in opposite directions and rotate synchronously, when the lifting pedal driving member 71 rotates downward, the supporting footrest member 11 is driven to rotate, and the supporting footrest member 11 drives the middle connecting rod 12 to rotate, thereby driving the lifting leg 42 to rise. In other possible embodiments, the gear transmission group 72 can also be set as a planetary gear or other transmission structure to achieve the requirement that the footrest connecting rod 11 and the lifting pedal driving member 71 rotate in opposite directions and rotate synchronously.

[0049] In some embodiments, a lifting stopper 8 is provided between the lifting pedal driving member 71 and the vehicle floor 10. When the lifting pedal driving member 71 rotates upward to a maximum angle relative to the vehicle floor 10, the lifting stopper 8 contacts the lifting pedal driving member 71 to limit the position of the lifting pedal driving member 71. By providing the lifting stopper 8, a certain space can be reserved between the lifting pedal driving member 71 and the vehicle floor 10 to avoid collision between the lifting pedal driving member 71 and the vehicle floor 10.

[0050] Specifically, in some embodiments, an elastic member 9 is provided between the vehicle floor 10 and the middle link 12. When the middle link 12 rotates downward to the maximum angle relative to the vehicle floor 10, the elastic member 9 is stretched to prevent the middle link 12 from continuing to rotate. In some embodiments, the elastic member 9 can be configured as a spring. When the lifting legs 42 are in a supporting state in contact with the ground, the spring is in a stretched state. When the unfolded pedal link 111 and the middle link 12 are folded back, the elastic member 9 can also provide a force for the middle link 12 to rotate upward, making the recovery of the legs more labor-saving.

[0051] Through the above arrangement, the liftable surgical trolley of the present application can drive the supporting connecting rod assembly to quickly lower the lifting legs and form a stable support with the ground. After use, it can be quickly retracted through the lifting assembly. The structure is simple, the support is reliable, and the operation is convenient. The pedal connecting rod of the supporting connecting rod assembly drives the middle connecting rod to rotate and move downward, which can push the connecting shaft to move downward, thereby driving the lifting legs to move downward. After the bottom of the lifting legs contacts the ground, it can be pushed in the reverse direction to lift the entire trolley, so that the casters of the trolley leave the ground, and the lifting legs provide stable support for the trolley.

[0052] What is disclosed above is only a preferred exemplary embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
