Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a medical equipment support device. Background Technology

[0002] A surgical robot is an advanced medical device that uses robotic technology to assist or perform surgical procedures. Currently, most surgical robots on the market are integrated into a medical device trolley, allowing for convenient and quick entry into the operating room and adjustment to follow the patient's position. To improve surgical precision and increase the success rate, the surgical robot needs to maintain a fixed relative position with the patient during the procedure. The medical device trolley is equipped with wheels at its bottom for moving the device on the ground. During surgery, the trolley is supported by these wheels; if the device's position is unstable and prone to swaying, the surgical robot will also sway, affecting the stability of the relative position between the robot and the patient.

[0003] To ensure the relative stability of the surgical robot and the patient, multiple lifting legs are installed on the trolley of the medical equipment. After determining the position of the medical equipment before surgery, each lifting leg is lowered, replacing the wheels for support on the ground, thus ensuring the stability of the medical equipment. However, the raising and lowering of these legs in related technologies relies on electric drives, and each leg is equipped with a corresponding electric drive, resulting in high costs. Furthermore, controlling the electric drives involves buttons and wiring, which are prone to malfunction. When a malfunction occurs, the lifting legs cannot be controlled, affecting the use of the medical equipment.

[0004] Therefore, how to solve the problems of high cost and high failure rate caused by the use of electric drive components in the lifting legs of medical equipment in related technologies has become an important technical problem to be solved by those skilled in the art. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] The following is combined with Figures 1 to 4 This invention describes a medical device support device.

[0025] like Figures 1 to 4 As shown, the medical equipment support device provided in this embodiment of the present invention includes a trolley base plate 1, walking wheels 2, operating components, a transmission mechanism, and multiple movable support legs.

[0026] Specifically, the trolley is used to support medical equipment, which can be fixed to the trolley. The trolley base plate 1 is the bottom support plate of the trolley, and the trolley base plate 1 supports the traveling wheels 2, operating parts, transmission mechanism and movable outriggers.

[0027] When the trolley is on a horizontal surface, the trolley base plate 1 is parallel to the horizontal plane, and the vertical direction of the trolley base plate 1 is along the vertical direction, as shown in the figure. Figure 1 The direction indicated by z. The longitudinal direction of the trolley base plate 1 is consistent with the front-to-back direction of the trolley, and the longitudinal direction of the trolley base plate 1 is as follows: Figure 1 The direction indicated by y; the lateral direction of the trolley base plate 1 is consistent with the left-right direction of the trolley, and the lateral direction of the trolley base plate 1 is as follows: Figure 1 The direction indicated by x. The vertical direction, the horizontal direction, and the longitudinal direction of the trolley base plate 1 are all perpendicular to each other.

[0028] The movable support includes a base 3 and a lifting support 4. The base 3 is fixedly installed at the bottom of the trolley base plate 1, and the lifting support 4 is installed on the base 3. The lifting support 4 can slide back and forth along the vertical direction of the trolley base plate 1.

[0029] The traveling wheel 2 is rotatably mounted on the base 3. When the lifting leg 4 slides vertically along the bottom plate 1 of the trolley, the relative position of the lifting leg 4 and the traveling wheel 2 along the vertical direction of the bottom plate 1 of the trolley changes. The lifting leg 4 can slide between the supported position and the stored position.

[0030] When the lifting support leg 4 slides to the storage position, the supporting end of the lifting support leg 4 is located above the lowest point of the traveling wheel 2. At this time, the traveling wheel 2 can support the ground and support the trolley base plate 1. When the traveling wheel 2 rotates, it can drive the trolley base plate 1 to move on the ground.

[0031] When the lifting leg 4 slides to the support position, the support end of the lifting leg 4 is located below the lowest point of the traveling wheel 2. At this time, the support end of the lifting leg 4 is supported on the ground, and the lifting leg 4 supports the trolley base plate 1. The traveling wheel 2 is lifted off the ground. Even if the traveling wheel 2 rotates, it will not cause the trolley base plate 1 to move on the ground, thus ensuring the stability of the trolley base plate 1.

[0032] An operating component is mounted on the trolley base plate 1 and receives mechanical force applied by the operator. A transmission mechanism is provided between the operating component and each lifting leg 4. This transmission mechanism drives and restricts the lifting leg 4 to switch between a supported position and a retracted position. Specifically, the transmission mechanism transmits the mechanical force of the operating component to the lifting leg 4. The mechanical force applied by the operator to the operating component is transmitted to the lifting leg 4 via the transmission mechanism, thereby causing the lifting leg 4 to switch between the supported and retracted positions. When the lifting leg 4 is in the supported position, the state of the transmission mechanism can also restrict the lifting leg 4 from switching to the retracted position when no mechanical force is applied to the operating component, ensuring that the lifting leg 4 remains stable in the supported position.

[0033] With this configuration, the lifting action of the lifting leg 4 is powered by the mechanical force applied by the operator to the operating components, avoiding the use of electric drive components. This effectively reduces costs and failure rates, and solves the problems of high cost and high failure rate caused by the use of electric drive components in the lifting leg 4 of medical equipment in related technologies.

[0034] In this embodiment of the utility model, the operating component is located above the trolley base plate 1, which facilitates operation by the operator and avoids the operating component occupying the space below the trolley base plate 1, thereby improving the trolley's passability.

[0035] The transmission mechanism includes a first transmission assembly and a second transmission assembly. The first transmission assembly is located above the trolley base plate 1, and its driving end is connected to the operating component, thereby transmitting power to the operating component and ensuring the normal operation of the entire mechanism.

[0036] The second transmission component is located below the trolley base plate 1, which saves space above the trolley base plate 1, optimizes the spatial layout of the trolley, and makes the overall structure of the trolley more compact.

[0037] The driving end of the second transmission component is connected to the driven end of the first transmission component, realizing the power transmission between the two transmission components. The driven end of the second transmission component is connected to the lifting leg 4, which transmits power to the lifting leg 4 to drive it to rise and fall. Through the cooperation of the two transmission components, relatively complex transmission requirements are met, improving the reliability and efficiency of the transmission.

[0038] With the lifting leg 4 in the supporting position, at least the second transmission component is in the dead center position. This cleverly utilizes the principle of mechanical dead center self-locking, ensuring that the reverse torque generated by the load cannot drive the second transmission component when the lifting leg 4 is in the supporting position. This achieves reliable self-locking without the need for any additional braking or locking devices. This design greatly improves the stability and safety of the movable leg when supporting the trolley, while also simplifying the structure, reducing costs, and enhancing the reliability of the medical equipment support device.

[0039] In this embodiment, the operating components include a rotating shaft 5 and a foot support 6. The axis of the rotating shaft 5 is arranged laterally along the trolley base plate 1, and the rotating shaft 5 can rotate relative to the trolley base plate 1 about its own axis and can move vertically along the trolley base plate 1.

[0040] The foot pedal bracket 6 is used to receive the operator's foot pressure. The operator inputs mechanical force to the operating component by stepping on it, making operation convenient. The foot pedal bracket 6 is fixedly mounted on the rotating shaft 5, ensuring that the operator's foot pressure can be reliably transmitted to the rotating shaft 5.

[0041] The two ends of the foot pedal bracket 6 are distributed along the longitudinal direction of the trolley base plate 1 on both sides of the rotating shaft 5. One end of the foot pedal bracket 6 is mounted on the trolley base plate 1 via the first support seat 7, as shown below. Figure 1 As shown. This layout creates an effective lever arm, generating sufficient torque to drive the rotating shaft 5 to rotate when the operator applies a pedaling force to one end of the pedal support 6, making operation easier. The first support 7 provides a stable support point for the entire operating component, ensuring its structural stability when subjected to pedaling force.

[0042] The connection structure between the first support 7 and the foot pedal bracket 6 allows the foot pedal bracket 6 to rotate around the axis of the pivot 5. This pivot structure works in conjunction with the rotation of the pivot 5 to ensure that the foot pedal bracket 6 can smoothly and flexibly perform the predetermined swing operation, thereby improving the reliability and accuracy of the operation.

[0043] In a further embodiment, a pair of motion connecting rods 8 are provided on the trolley base plate 1. The pair of motion connecting rods 8 are distributed laterally at intervals along the trolley base plate 1. The motion connecting rods 8 can slide back and forth vertically along the trolley base plate 1. The two ends of the rotating shaft 5 are respectively hinged to the pair of motion connecting rods 8. Through the vertical sliding of the motion connecting rods 8, the lifting and lowering of the rotating shaft 5 can be accommodated, and the stability of the lifting and lowering action of the rotating shaft 5 can be ensured.

[0044] The first support base 7 is fixed to the trolley base plate 1. One end of the foot pedal bracket 6 is hinged to the first support base 7 via a hinge shaft, the axis of which is parallel to the axis of the rotating shaft 5. This ensures that the foot pedal bracket 6 and the related components of the rotating shaft 5 move in a coordinated manner, avoiding motion interference and jamming, and making the entire operating component operate more smoothly.

[0045] The hinge hole on the pedal bracket 6 that mates with the hinge shaft is a strip-shaped hole, as shown in the reference. Figure 4 The slotted hole allows the hinge shaft of the first support seat 7 to slide along the length of the slotted hole when the foot pedal bracket 6 rotates around the pivot 5, thus smoothly transmitting the movement of the foot pedal bracket 6 to the second transmission mechanism, avoiding movement jamming, and ensuring the smoothness and reliability of the entire operating component.

[0046] In this embodiment of the present invention, the second transmission assembly includes a first connecting member 9, a second connecting member 10, a third connecting member 11, and a fourth connecting member 12, as follows: Figure 2 As shown.

[0047] The first connecting member 9 is slidably disposed on the trolley base plate 1 and the base 3 along the vertical direction of the trolley base plate 1. The first end of the first connecting member 9 is connected to the driven end of the first transmission assembly. The first transmission assembly is used to convert the rotation and movement of the rotating shaft 5 relative to the trolley base plate 1 into the sliding movement of the first connecting member 9 relative to the trolley base plate 1.

[0048] The first end of the second connector 10 is hinged to the second end of the first connector 9. This hinge structure can reliably transmit the thrust or pull from the first connector 9, while allowing the second connector 10 to swing, providing the necessary degrees of freedom for subsequent motion conversion.

[0049] The third connecting member 11 is rotatably mounted on the base 3, and its rotation axis relative to the base 3 is parallel to the axis of the rotating shaft 5. The third connecting member 11 is hinged to the second end of the second connecting member 10. The third connecting member 11 provides a stable fulcrum and torque conversion center for the second transmission assembly, converting the linear motion of the first connecting member 9 into precise circular oscillation. Simultaneously, the parallelism between the rotation axis of the third connecting member 11 and the axis of the rotating shaft 5 ensures the smoothness of the second transmission assembly during movement, avoiding jamming or abnormal wear caused by asynchronous movement.

[0050] The first end of the fourth connector 12 is hinged to the third connector 11, and the second end of the fourth connector 12 is hinged to the lifting leg 4. As the final transmission rod, the fourth connector 12 accurately transmits the swinging motion of the third connector 11 to the lifting leg 4, thereby causing the lifting leg 4 to slide relative to the base 3, realizing the sliding of the lifting leg 4 between the supporting position and the storage position, and achieving complete motion transmission.

[0051] In a specific embodiment, the hinge points of the third connector 11 and the second connector 10, the hinge points of the third connector 11 and the base 3, and the hinge points of the third connector 11 and the fourth connector 12 are arranged in a triangular pattern. When the lifting leg 4 is in the supporting position, the straight line containing the hinge points of the third connector 11 and the base 3, the hinge points of the third connector 11 and the fourth connector 12, and the hinge points of the fourth connector 12 and the lifting leg 4 is along the vertical direction of the trolley base plate 1.

[0052] Through a clever "three-point collinearity" layout, the supporting force from the ground can be directly transmitted to the base 3 and the trolley base 1 vertically through these three hinge points when the lifting outrigger 4 is in the supported state. This prevents the driving torque that would cause the lifting outrigger 4 to slide into the retracted position, thus achieving mechanical self-locking. This design greatly improves the stability and safety of the support, ensuring that the lifting outrigger 4 can reliably remain in the supported position even when the foot support 6 is not under foot pressure.

[0053] In this embodiment, a limiting post 13 is provided on the base 3, and a limiting hole 14 is provided on the third connecting member 11. The limiting hole 14 allows the limiting post 13 to pass through, and the limiting hole 14 extends along an arc. The center of the arc is located on the rotation axis of the third connecting member 11 relative to the base 3, and the limiting post 13 and the limiting hole 14 are slidably engaged. Through simple mechanical engagement, the rotation range of the third connecting member 11 can be effectively limited, resulting in a reliable structure and low cost. During the rotation of the third connecting member 11, the limiting post 13 can slide smoothly along a predetermined trajectory within the limiting hole 14 without interference or jamming, ensuring the smoothness and stability of the second transmission component's operation.

[0054] When the lifting leg 4 is in the supported position, the limiting post 13 abuts against one end sidewall of the limiting hole 14. When the lifting leg 4 is in the retracted position, the limiting post 13 abuts against the other end sidewall of the limiting hole 14. The cooperation between the limiting hole 14 and the limiting post 13 limits the extreme rotational position of the third connecting member 11, providing a stable and reliable physical stop for the lifting leg 4 in both the supported and retracted positions, ensuring that the lifting leg 4 can stably remain in the supported position and provide effective support for the trolley base plate 1. Furthermore, when the lifting leg 4 is in the supported position, the second transmission assembly is in the dead center position. When a stepping force is applied to the foot support 6 to switch the lifting leg 4 to the retracted position, the obstruction of the limiting post 13 by the end sidewall of the limiting hole 14 forcibly limits the rotation direction of the third connecting member 11 relative to the base 3, ensuring that the rotation of the second connecting member 10, the third connecting member 11, and the fourth connecting member 12 proceeds sequentially, avoiding disordered rotation.

[0055] In this embodiment of the present invention, the first transmission assembly includes a third support base 15, a fifth connector 16, a sixth connector 17, and a seventh connector 18, as shown in the reference. Figure 2 .

[0056] The third support base 15 is fixedly installed on the trolley base plate 1, and along the longitudinal direction of the trolley base plate 1, the third support base 15 is located on one side of the rotating shaft 5. The fifth connecting piece 16, the sixth connecting piece 17 and the seventh connecting piece 18 are connected in series and hinged. The first end of the fifth connecting piece 16 is hinged to the end of the rotating shaft 5, and the hinge hole of the first end of the fifth connecting piece 16 that mates with the rotating shaft 5 is a strip hole. The middle part of the sixth connecting piece 17 is hinged to the third support base 15, and the second end of the seventh connecting piece 18 is hinged to the first end of the first connecting piece 9.

[0057] The strip-shaped hole at the end of the fifth connector 16 allows the fifth connector 16 to swing, providing the necessary degrees of freedom for subsequent motion conversion.

[0058] The third support 15 and the sixth connector 17 cooperate to form a lever, which can efficiently transmit and convert motion and mechanical force, effectively converting the motion trajectory of the fifth connector 16 and transmitting it to the seventh connector 18, which is key to achieving a specific motion trajectory. Furthermore, the third support 15 provides a stable and reliable hinge base for the first transmission assembly, ensuring the smoothness and accuracy of subsequent connector movements. The fifth connector 16, the sixth connector 17, and the seventh connector 18 are sequentially connected in series to form a multi-link mechanism. This structure is simple in design and reliable in transmission, effectively converting the rotational and lateral movements of the shaft 5 into the final required specific trajectory motion.

[0059] The seventh connector 18 accurately outputs the final motion converted by the first transmission component to the first connector 9, so as to drive the second transmission component and the lifting support 4 to complete the predetermined action, thus realizing the complete power and motion transmission.

[0060] In a specific embodiment, the end of the foot pedal bracket 6 furthest from the first support base 7 is the first end of the foot pedal bracket 6, and the other end is the second end. When a stepping force is applied to the first end of the foot pedal bracket 6, the first connecting member 9 moves upward and the lifting foot 4 moves downward until the first transmission assembly is at its dead point, at which point the lifting foot 4 remains in the support position. When a stepping force is applied to the second end of the foot pedal bracket 6, the first connecting member 9 moves downward and the lifting foot 4 moves upward, allowing the lifting foot 4 to switch to the retracted position. The first end and the second end of the foot pedal bracket 6 are located on opposite sides of the rotating shaft 5 to avoid confusion.

[0061] Both the first and second transmission assemblies are linkage assemblies, and the first connector 9, the second connector 10, the fourth connector 12, the fifth connector 16, the sixth connector 17, and the seventh connector 18 are all rod-shaped. The third connector 11 is triangular in shape.

[0062] In a further embodiment, the operating component also includes a locking component 19, which is disposed between the foot support 6 and the first support base 7. The locking component 19 can switch to the locked state at least when the lifting leg 4 is in the retracted position, so as to restrict the movement of the foot support 6 relative to the first support base 7, thereby improving the stability of the lifting leg 4 in the retracted position. This can prevent the lifting leg 4 from switching to the support position on its own due to accidental collisions or vibrations, and prevent the lifting leg 4 from interfering with the movement of the trolley.

[0063] In a specific embodiment, the locking assembly 19 includes a locking groove and a spring ball. One of the locking groove and the spring ball is disposed on the foot pedal bracket 6, and the other is disposed on the first support base 7. The locking groove faces the spring ball and is a tapered groove.

[0064] The spring-loaded ball has an elastic element and a ball 20. Under the action of the elastic element, the ball 20 tends to move closer to the locking groove. The locking groove, in the form of a tapered groove, can effectively guide and center the ball 20, making the process of the ball 20 entering and exiting the locking groove smoother, avoiding jamming, and improving the convenience of operation.

[0065] When the foot support 6 moves to the position where the lifting foot 4 is in the retracted position, the top bead 20 is aligned with the locking groove. When the top bead 20 is located in the locking groove under the action of the elastic element, the relative movement between the foot support 6 and the first support seat 7 can be restricted through the interaction between the top bead 20 and the side wall of the locking groove.

[0066] When it is necessary to switch the lifting support leg 4 to the support position, the operator applies force to the foot support 6. The force exerted by the side wall of the locking groove on the top ball 20 can overcome the elastic force of the elastic element. The top ball 20 gradually moves out of the locking groove, releasing the restriction on the foot support 6 and the first support seat 7.

[0067] The foot pedal bracket 6 is positioned and locked by the cooperation of the spring-loaded ball and the locking groove. This structure is simple in design, low in manufacturing cost, and reliable in operation.

[0068] In this embodiment, two pairs of movable legs are provided. The two pairs of movable legs are distributed laterally along the bottom plate 1 of the trolley, and each pair of movable legs is distributed longitudinally along the bottom plate 1 of the trolley. This arrangement allows the four movable legs to form a rectangular distribution, which can constitute a large supporting quadrilateral, greatly increasing the support area of ​​the trolley. This effectively improves the overall stability and anti-overturning ability of the trolley in the supported state, ensuring the safety of the operation process.

[0069] Each movable support leg corresponds to a first transmission component and a second transmission component, with the second transmission component for each pair of movable support legs connected to the same end of the rotating shaft 5. This configuration allows the lifting legs 4 of both pairs of movable support legs to be driven by a single rotating shaft 5, achieving synchronous lifting and lowering of the lifting legs 4 and ensuring that the support height on both sides of the trolley base 1 remains consistent. Furthermore, it avoids the problem of tilting or swaying of the trolley base 1 caused by the independent movement of individual movable support legs 4. This not only simplifies the transmission mechanism and reduces costs and failure rates, but also significantly improves the stability, reliability, and operational efficiency of the lifting legs 4 during support and storage processes.
