Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a brake structure for a surgical operation console. Background Art

[0002] The improvement of science and technology is also reflected in the medical level. The laparoscopic surgery system uses minimally invasive methods to perform complex surgical operations. Compared with traditional surgery, it has the advantages of precision, sensitivity, clarity, efficiency, and intelligence. As an important part of the laparoscopic surgery system, the doctor's console should not only be easy to move and fix, but also have the characteristics of simple and labor-saving operation. At the same time, it should be linked with other structures to facilitate the operation of medical staff.

[0003] The chassis is the supporting part of the doctor's console and also the walking part of the doctor's console. In order to ensure that the doctor's console has a certain turning or rotation ability during the movement, at least one set of universal wheels can be set on the chassis. In order to achieve the braking of the universal wheels, a brake structure is set between the two universal wheels in the related art, and the purpose of synchronous braking of the two universal wheels is achieved by stepping on the brake pedal. However, when releasing the universal wheel, the brake pedal needs to be stepped on in the opposite direction. The setting of this brake structure is not only easy to misoperate and inconvenient to operate, but also has insufficient locking force. The transmission component connected to the brake pedal is very easy to loosen, which can easily cause the doctor's console to move, thereby affecting the surgical operation process. Utility Model Content

[0004] An embodiment of the present application provides a brake structure for a surgical operation console, which maintains the pedal in a downward or initial position through the cooperation between the foot pedal assembly, the self-locking assembly and the rebound assembly, thereby facilitating the transmission assembly to maintain the caster in a self-locking state or an unlocked state.

[0005] The embodiment of the present application provides a brake structure for a surgical operation console, comprising:

[0006] A chassis, provided with at least one set of casters;

[0007] The pedal assembly comprises an A plate and a B plate which are fixed to each other and form an angle, wherein the B plate is provided with a guide ring groove, and the guide ring groove has a locking position and a releasing position;

[0008] A rebound assembly, used to support the pedal assembly, one end of the rebound assembly is fixedly arranged on the chassis, and the other end is fixedly connected to the A plate, so as to deform and store force when the A plate moves downward;

[0009] The self-locking component has one end disposed at the fixed end of the chassis or the resilient component, and the other end is provided with a slider and a first elastic member. The slider is located in the guiding ring groove. One end of the first elastic member is fixed, and the other end is limited to the slider. The slider can rotate forward or backward along the guiding ring groove under the restriction of the first elastic member;

[0010] The transmission component is installed between the foot pedal component and the caster wheel;

[0011] Wherein, when pressure acts on the A plate, the resilient component is in a compressed state. The transmission component rotates driven by the foot pedal component to lock the caster wheel. At the same time, the B plate moves downward, causing the slider to slide relatively in the guiding ring groove to the locking position, so that the caster wheel maintains the self-locking state;

[0012] When pressure acts on the A plate again, the slider slides out of the locking position under the action of the first elastic member. The resilient component releases force to bounce back the foot pedal component. The transmission component rotates driven by the foot pedal component to unlock the caster wheel. At the same time, the slider slides relatively in the guiding ring groove to the release position, so that the caster wheel maintains the unlocked state.

[0013] In a feasible implementation manner, the guiding ring groove further has a first high position and a second high position. The locking position is on the guiding path of the guiding ring groove between the first high position and the second high position. The first high position, the locking position and the second high position are on the side of the guiding ring groove close to the A plate, and the release position is on the side of the guiding ring groove far from the A plate.

[0014] In a feasible implementation manner, the guiding ring groove has a special-shaped block in the middle. The special-shaped block includes a limiting block extending towards the A plate. The limiting block is configured to cooperate with the resilient component to block the slider moving in the guiding ring groove, so that the slider is located at the locking position.

[0015] In a feasible implementation manner, a step is formed in the guiding ring groove on the release position side. The step is on the moving path of the slider from the locking position to the release position.

[0016] In a feasible implementation manner, the braking structure is configured to perform one of the following actions when using the surgical operation console:

[0017] The A plate moves downward under an external force. The elastic return assembly stores energy under the movement of the A plate. The slider moves relatively within the guiding ring groove. As the A plate continues to move downward, the slider moves from the release position to the first high position. After the external force on the A plate is removed, driven by the force release of the elastic return assembly and the pulling force of the first elastic member, the slider moves from the first high position to the locking position.

[0018] The A plate moves downward under an external force, causing the slider to move from the locking position to the second high position. After the external force on the A plate is removed, driven by the force release of the elastic return assembly and the pulling force of the first elastic member, the slider passes through the step and reaches the release position from the second high position.

[0019] In a feasible implementation, the elastic return assembly includes:

[0020] A bottom plate, fixedly connected to the chassis;

[0021] A guiding member, with one end fixedly connected to the A plate and the other end sliding through the bottom plate;

[0022] A spring, sleeved on the guiding member, with one end of the spring limited by the A plate and the other end limited by the bottom plate.

[0023] In a feasible implementation, one end of the self-locking assembly is fixed on the bottom plate;

[0024] The self-locking assembly includes:

[0025] A first adjusting rod, rotatably arranged on the bottom plate;

[0026] A second adjusting rod, forming an angle with the first adjusting rod and fixed to each other. The end of the second adjusting rod away from the first adjusting rod is provided with the slider;

[0027] Wherein, the axis of the first adjusting rod is perpendicular to the plane where the guiding ring groove is located; one end of the first elastic member is fixed to the bottom plate and the other end is connected to the second adjusting rod.

[0028] In a feasible implementation, the self-locking assembly further includes:

[0029] A second elastic member, sleeved on the first adjusting rod, and one end of the second elastic member is limited by the second adjusting rod and the other end is limited by the bottom plate, so that the slider abuts against the bottom surface of the guiding ring groove.

[0030] In a feasible implementation, a first linear bearing and a second linear bearing are further provided at the bottom plate. The first linear bearing is used for installing the guiding member, and the second linear bearing is used for installing the first adjusting rod;

[0031] Wherein, the axis of the first linear bearing is perpendicular to the axis of the second linear bearing.

[0032] In a feasible implementation manner, the transmission assembly includes:

[0033] A fixed shaft, hinged to the A plate or the B plate;

[0034] A first connecting rod, one end of which is hinged to the fixed shaft;

[0035] A second connecting rod, one end of which is hinged to the other end of the first connecting rod;

[0036] A prism rod, one end of which is connected to the other end of the second connecting rod, and the other end is connected to the locking device on the caster. The prism rod is configured to rotate under the transmission of the fixed shaft, the first connecting rod, and the second connecting rod during the process of the pedal assembly being moved by an external force.

[0037] In a feasible implementation manner, the prism rod is a hexagonal shaft;

[0038] The locking device is provided with a hexagonal hole in the caster. One end of the hexagonal shaft away from the second connecting rod is inserted into the hexagonal hole to drive the locking device through the rotation of the hexagonal shaft;

[0039] And / or, a transition bracket is provided on the chassis between the pedal assembly and the caster, so that the hexagonal shaft is inserted into the transition bracket through a bearing.

[0040] The braking structure for the surgical operation console provided by the embodiments of the present application realizes the purpose of stepping on the pedal once, the slider reaches the locking position along the guiding ring groove, and the pedal assembly is stably positioned after moving downward, and the caster is switched to the self-locking state through the transmission assembly by setting a self-locking assembly and a spring-back assembly at the pedal assembly and through the cooperation of the guiding ring groove and the slider between the pedal assembly and the self-locking assembly, as well as the cooperation between the pedal assembly and the spring-back assembly; and it can also realize the purpose of stepping on the pedal once, the slider disengages from the locking position, and under the driving of the first elastic member and the force release action of the spring-back assembly, the slider reaches the release position along the guiding ring groove, and the pedal is restored to the release position, and the caster is switched to the unlocked state through the transmission assembly. The present application can realize the purpose of the caster being in the self-locking state or the unlocked state by stepping on the pedal assembly, without the need to operate the pedal assembly in the reverse direction, thereby improving the operation accuracy and convenience, and greatly enhancing the locking force at the caster, avoiding the situation that the doctor's console moves or shakes due to the loosening of the caster.

[0061] Before introducing the braking structure for the surgical operation console of the embodiments of this application, first, a brief introduction to the surgical operation console is given. Taking the laparoscopic surgical robot as an example, as Figure 1 shown, it is composed of three parts: a surgical cart, a doctor's console, and an instrument cart. The doctor's console, that is, the surgical operation console, can be composed of four parts: a chassis 10, a foot pedal 20, an armrest 30, and a head-mounted display 40. In this application, the structure at the chassis 10 is mainly designed so that the doctor's console can be easily transported or moved, and can be fixed in position during the operation to ensure that it cannot move or shake.

[0062] To achieve the above object, the embodiments of this application provide a braking structure for a surgical operation console, Figure 2 which is a schematic structural diagram of the braking structure provided by the embodiments of this application; Figure 3 which is an assembled structural diagram of the self-locking component and the pedal component provided by the embodiments of this application; Figure 4 which is a schematic structural diagram of the guide ring groove in the pedal component provided by the embodiments of this application; Referring to Figures 2 - 4 shown, the braking structure can include a chassis 10, a self-locking component 130, a foot pedal component 200, a return component 120, and a transmission component 300.

[0063] The chassis 10 is provided with at least one set of casters 50; the foot pedal assembly 200 includes a plate A 210 and a plate B 220 which form an included angle and are fixed to each other. The plate B 220 is configured with a guiding annular groove 201 which has a locking position 201a and a releasing position 201b; the resilient assembly 120 is used to support the foot pedal assembly 200. One end of the resilient assembly 120 is fixedly arranged on the chassis 10, and the other end is fixedly connected to the plate A 210 so as to deform and store energy when the plate A 210 moves downward; one end of the self-locking assembly 130 is arranged on the chassis 10 or the fixed end of the resilient assembly 120, and the other end is provided with a slider 133 and a first elastic member 134. The slider 133 is located in the guiding annular groove 201. One end of the first elastic member 134 is fixed, and the other end is limited to the slider 133. The slider 133 can rotate forward or backward along the guiding annular groove 201 under the limitation of the first elastic member 134; the transmission assembly is installed between the foot pedal assembly 200 and the casters 50.

[0064] Wherein, when pressure acts on the plate A 210, the resilient assembly 120 is in a compressed state. The transmission assembly 300 rotates driven by the foot pedal assembly 200 so that the casters 50 are self-locked. At the same time, the plate B 220 moves downward, so that the slider 133 relatively slides in the guiding annular groove 201 to the locking position 201a, so as to maintain the casters 50 in a self-locked state; when pressure acts on the plate A 210 again, the slider 133 slides out of the locking position 201a under the action of the first elastic member 134. The resilient assembly 120 releases force to bounce back the foot pedal assembly 200. The transmission assembly 300 rotates back driven by the foot pedal assembly 200 so that the casters 50 are unlocked. At the same time, the slider 133 relatively slides in the guiding annular groove 201 to the releasing position 201b, so as to maintain the casters 50 in an unlocked state.

[0065] It can be understood that the chassis 10 not only serves as a supporting component of the doctor's console, but also functions as a walking component of the doctor's console. Other components (such as the foot pedal lifting assembly, the foot pedal telescopic assembly, and the braking structure in the present application) are all built on the basis of the chassis 10. Therefore, the chassis 10 needs to have good strength and stiffness requirements. In this example, reinforcing ribs 11 can be added under its bottom plate 110 to increase its rigidity and strength to meet its load-bearing requirements.

[0066] Regarding the design of the casters 50 on the chassis 10, a set of linear wheels 60 can be arranged at one end (front side) of the chassis 10, and a set of universal wheels can be arranged at the other end (rear side). The linear wheels 60 can ensure the straight walking degree of the doctor's console and prevent it from deviating during walking, while the universal wheels increase its flexibility, have a certain turning or rotating ability, and at the same time meet the obstacle-crossing ability.

[0067] To achieve the overall fixation of the doctor's console during the operation and ensure the stability after the above-mentioned casters 50 (swivel casters) are locked, a self-locking component 130 and a spring-back component 120 are provided on the chassis 10. The self-locking component 130 and the spring-back component 120 are arranged at the foot pedal component 200 and need to cooperate with the guide ring groove 201 of the foot pedal component 200 to achieve the transmission stability of the transmission component 300, and then achieve the self-locking or unlocking of the caster 50, especially to ensure the stability of the caster 50 in the self-locked state.

[0068] To facilitate the description of the structure of the foot pedal component 200, the foot pedal component 200 is disassembled into a plate A 210 and a plate B 220 for description. The plate A 210 is a horizontal plate for the user to step on with the foot, and the plate B 220 can be a vertical plate. That is, the plate A 210 and the plate B 220 form an L-shaped pedal structure. In addition, a guide ring groove 201 is constructed on the inner side of the plate B 220, and the guide ring groove 201 is used to cooperate with the slider 133 in the self-locking component 130 to lock the plate B 220 (foot pedal component) in the downward position or unlock it to the initial position.

[0069] The plate A 210 can move downward under the action of an external force. To achieve the reset of the plate A 210, a spring-back component 120 is provided below the plate A 210. The bottom end of the spring-back component 120 is fixedly connected to the chassis 10, and the top end is fixedly connected to the plate A 210 to store energy by deforming during the downward movement of the plate A 210 under the action of an external force.

[0070] To avoid the situation that after each step on the plate A 210 (when the external force is lost), the plate A 210 returns to the initial position under the action of the released force of the spring-back component 120, thereby driving the transmission component 300 to unlock the caster 50 and making the caster 50 unable to maintain the self-locked state. In this example, a self-locking component 130 is also provided. One end of the self-locking component 130 can be fixed to the chassis 10 or the fixed end of the spring-back component 120. That is, this end of the self-locking component 130 should be stationary relative to the chassis 10, and the other end is provided with a slider 133 and a first elastic member 134. The slider 133 is embedded in the guide ring groove 201 and can move in the guide ring groove 201 when the plate A 210 (plate B 220) moves downward. For example, it can move to the stop position 201a of the guide ring groove 201, that is, to keep the guide ring groove 201 and the slider 133 relatively stationary, so that the plate A 210 loses the ability to spring back to the initial position. Similarly, when it is necessary to let the plate A 210 return to the initial position, a force can be applied to the plate A 210 to make the slider 133 and the guide ring groove 201 move relative to each other, facilitating the slider 133 to escape from the stop position 201a, and with the action of the first elastic member 134, making the slider 133 move away from the stop position, and then under the action of the spring-back component 120, making the slider 133 slide to the release position 201b of the guide ring groove 201, that is, the plate A 210 returns to the initial position.

[0071] It should be noted that in this example, the initial position of the A plate 210 is the position where the A plate 210 is located when the casters can move freely. The first elastic member 134 can be understood as a tension spring or a compression spring. The movement of the slider 133 in the guiding ring groove 201 can rotate one full circle clockwise or counterclockwise. Regardless of the above-mentioned movement trajectory, the up-and-down movement of the slider 133 in the guiding ring groove 201 can be achieved by applying an external force to the A plate 210 or by the release of the elastic return assembly 120 to drive the A plate 210. However, the left-and-right movement of the slider 133 in the guiding ring groove 201 needs to be achieved by means of the first elastic member 134. Otherwise, it will be difficult to realize the process of the slider 133 moving from the locking position 201a to the release position 201b to unlock the caster 50.

[0072] More specifically, a locking device is provided at the caster 50. However, this locking device requires external drive to lock or release the caster 50. Therefore, a transmission assembly 300 is provided between the caster 50 and the A plate 210. The transmission assembly 300 can convert the linear motion of the movement of the pedal assembly 200 into a rotational motion of the locking device at the caster 50. After the doctor steps on the A plate 210, the transmission assembly 300 connected to the A plate 210 or the B plate 220 can rotate to trigger the locking device to lock the caster 50. In this example, the setting of the self-locking assembly 130 and the elastic return assembly 120 can solve the problem that the caster 50 is not firmly locked due to the loosening of the transmission assembly 300 after the external force on the A plate 210 is removed.

[0073] To ensure the up-and-down movement of the pedal assembly in cooperation with the elastic return assembly 120 and the self-locking assembly 130, the pedal assembly is arranged on the elastic return assembly 120, and the self-locking assembly 130 is arranged at the inner side position of the B plate 220, so that the guiding ring groove 201 on one side of the B plate 220 can move up or down relative to the self-locking assembly 130. Specifically, during the process of the caster 50 transitioning from the self-locking state - unlocking state - self-locking state, the slider 133 makes a one-way circular motion along the guiding ring groove 201, that is, the slider 133 moves from the release position 201b - locking position 201a - release position 201b.

[0074] The connection manner of the self-locking assembly 130, the elastic return assembly 120 and the pedal assembly 200 is as follows:

[0075] The deformation direction of the rebound component 120 is consistent with the moving direction of the A plate 210 (moving up and down), and the A plate 210 is arranged above the rebound component 120, and the rebound component 120 can be deformed and stored by stepping on the A plate 210 with external force. The slider 133 is arranged toward the guide ring groove 201 and is embedded in the guide ring groove 201, so that when the guide ring groove 201 moves up and down with the B plate 220, the slider 133 is forced to move in the guide ring groove 201, so that the slider 133 reaches the locking position 201a (the caster 50 is in a self-locking state) or the release position 201b (the caster 50 is in an unlocked state).

[0076] It should be noted that the rebound component 120 can be a return spring. To ensure that the A plate 210 does not deflect during movement, a plurality of return springs can be evenly arranged between the A plate 210 and the chassis 10, but there is no specific limitation.

[0077] The working principle of the self-locking component 130 is:

[0078] When the caster 50 needs to be in a self-locking state, an external force is used to step on the A plate 210 to move downward, thereby driving the transmission component 300 to rotate to trigger the locking device in the caster 50, thereby locking the caster 50; at the same time, the A plate 210 moves downward to compress the rebound component 120, causing the rebound component 120 to deform and accumulate force, and drives the guide ring groove 201 to move downward through the B plate 220, that is, the slider 133 embedded in the guide ring groove 201 can move relatively in the guide ring groove 201 until the slider 133 reaches the stop position 201a. Even if the A plate 210 is released, the slider 133 will be stabilized at the stop position 201a due to the release of the force of the rebound component 120, thereby avoiding the situation where the locking part of the caster 50 is firmly fixed due to the loosening of the transmission component 300.

[0079] When the caster 50 needs to be in an unlocked state, the A plate 210 is lightly stepped on by an external force, firstly causing the slider 133 to disengage from the locking position 201a, and then the external force is removed, and the A plate 210, the B plate 220, and the guide ring groove 201 will move upward under the force release of the rebound component 120, thereby driving the transmission component 300 to rotate so that the locking device is reset, and the caster 50 can move freely; at the same time, the slider 133 makes relative motion in the guide ring groove 201, so as to move from the position after disengaging from the locking position 201a to the release position 201b, and the A plate 210 is also restored to the initial position under the drive of the rebound component 120, so as to facilitate the next use of locking the caster 50.

[0080] In this application, by providing a self-locking component 130 and a spring-back component 120 at the foot pedal assembly 200, through the cooperation between the guide ring groove 201 and the slider 133 between the foot pedal assembly 200 and the self-locking component 130, and the cooperation between the foot pedal assembly 200 and the spring-back component 120, when the A plate 210 is stepped on once, the slider 133 reaches the locking position 201a along the guide ring groove 201, and the foot pedal assembly 200 is stably positioned after moving downward. Through the transmission component 300, the caster 50 is switched to the self-locking state; and it can be achieved that when the A plate 210 is stepped on once, the slider 133 disengages from the locking position 201a, and under the driving of the first elastic member 134 and the force release action of the spring-back component 120, the slider 133 reaches the release position 201b along the guide ring groove 201, and the A plate 210 is restored to the release position. Through the transmission component 300, the caster 50 is switched to the unlocked state. In this application, by stepping on the foot pedal assembly, the purpose of the caster 50 being in the self-locking state or the unlocked state can be achieved, without the need to operate the foot pedal assembly 200 in the reverse direction, thereby improving the operation accuracy and convenience, and greatly enhancing the locking force at the caster 50, avoiding the situation that the caster 50 loosens and causes the doctor's console to move or shake.

[0081] It should be noted that anti-slip patterns can be constructed on the upper surface of the A plate 210 to increase the friction between the A plate 210 and the sole of the shoe, so as to ensure the operation stability when the doctor steps on the A plate 210 with the foot.

[0082] Next, the specific structure of the braking structure provided by the embodiments of the present application will be described in detail with reference to the attached Figure 2 - attached Figure 8 drawings.

[0083] To avoid the problem that the A plate 210 is prone to skew during the downward movement due to the setting of the spring-back component 120 below, as Figure 3 shown, in some embodiments, the spring-back component 120 further includes a bottom plate 110, a guide member 121 and a spring 122. The bottom plate 110 is fixedly connected to the chassis. One end of the guide member 121 is fixedly connected to the A plate 210, and the other end slides through the bottom plate 110. The spring-back component 120 is sleeved on the guide member 121. One end of the spring-back component 120 is limited at the bottom of the A plate 210, and the other end is limited at the bottom plate 110; the spring 122 is sleeved on the guide member 121. One end of the spring 122 is limited at the A plate 210, and the other end is limited at the bottom plate 110.

[0084] Specifically, to facilitate the fixed connection between the spring-back component 120 and the self-locking component 130 and the chassis 10, a bottom plate 110 is provided to support the spring-back component 120 and the self-locking component 130, and the bottom plate 110 is fixedly connected to the chassis 10.

[0085] The guiding member 121 can be a guiding column, whose axial direction is along the vertical direction. To be able to move along with the movement of the A plate 210, the upper end of the guiding member 121 can be fixed to the bottom of the A plate 210, and the lower end is slidably inserted through the bottom plate 110. The spring 122 is sleeved on the guiding member 121 and can be compressed during the downward movement of the A plate 210 to store energy. After the external force on the A plate 210 is removed, it can release the energy to drive the A plate 210 to move upward or have a tendency to move upward.

[0086] Similarly, to ensure that the A plate 210 does not deflect during downward movement, two symmetric guiding members 121 or more guiding members 121 can be provided between the A plate 210 and the bottom plate 110, and the specific number is not limited here.

[0087] Since the bottom plate 110 is fixed to the chassis 10 and the guiding ring groove 201 has a certain width, to enable the slider 133 to move relative to the guiding ring groove 201, Figure 5 is a schematic cross-sectional structure diagram of the self-locking assembly and the A plate assembly provided by the embodiment of the present application;

[0088] Figure 6 is Figure 5 an enlarged schematic diagram of the structure at A in. As Figure 5 and Figure 6 shown, in some embodiments, one end of the self-locking assembly 130 is fixed to the bottom plate 110; the self-locking assembly 130 can include a first adjusting rod 131 and a second adjusting rod 132. The first adjusting rod 131 is rotatably arranged on the bottom plate 110; the second adjusting rod 132 forms an angle with the first adjusting rod 131 and is fixedly connected to each other. A slider 133 is arranged at the end of the second adjusting rod 132 facing away from the first adjusting rod 131; wherein, the axis of the first adjusting rod 131 is perpendicular to the plane where the guiding ring groove 201 is located; one end of the first elastic member 134 is fixed to the bottom plate 110, and the other end is connected to the second adjusting rod 132.

[0089] Specifically, the self-locking structure composed of the first adjusting rod 131, the second adjusting rod 132 and the slider 133 can be regarded as an integral structure. The first adjusting rod 131 and the second adjusting rod 132, and the second adjusting rod 132 and the slider 133 are perpendicularly arranged. The first adjusting rod 131 is rotatably arranged in the bottom plate 110, that is, with the axis of the first adjusting rod 131 as the origin, the second adjusting rod 132 and the slider 133 can have the freedom degree in the width direction of the guiding ring groove 201 (the plane formed by the rotation of the second adjusting rod 132 is parallel to the plane where the guiding ring groove 201 is located), realizing the possibility that the slider 133 performs a one-way circumferential movement along the guiding ring groove 201 during the upward or downward movement of the guiding ring groove 201.

[0090] To enable the slider 133 to reach the locking position 201a or the release position 201b more accurately, as Figure 5 andFigure 6 As shown, in some embodiments, the self-locking assembly 130 may further include a second elastic member 180. The second elastic member 180 is sleeved on the first adjusting rod 131, and one end of the second elastic member 180 is limited to the second adjusting rod 132, and the other end is limited to the bottom plate 110, so that the slider 133 abuts against the bottom surface of the guiding ring groove 201.

[0091] Specifically, by arranging the second elastic member 180, i.e., the spring, between the second adjusting rod 132 and the bottom plate 110, the distance between the second adjusting rod 132, the slider 133 and the guiding ring groove 201 can be adjusted, so that the slider 133 abuts against the bottom surface of the guiding ring groove 201. This setting can, on the one hand, prevent the slider 133 from disengaging from the guiding ring groove 201, and on the other hand, can limit the moving direction of the slider 133 along the guiding ring groove 201 (the setting of the inner step 2011 in the following guiding ring groove 201).

[0092] It should be noted that the fixed end of the first elastic member 134 in the above example can be connected to the bottom plate 110 or the chassis, which is not limited here, but it is necessary to ensure that the spring 122, i.e., the first elastic member 134, has the function of pulling the second adjusting rod 132 in a certain direction, and this direction can be the direction along the width of the guiding ring groove 201. The function of the first elastic member 134 is specifically reflected in that when the caster 50 needs to be switched to the unlocked state, gently step on the A plate 210 to make the guiding ring groove 201 move downward relative to the slider 133, that is, the slider 133 moves upward relative to the guiding ring groove 201, so as to disengage from the locking position 201a. Subsequently, when the external force is withdrawn, under the action of the spring-back assembly 120, the guiding ring groove 201 moves upward relative to the slider 133, that is, the slider 133 has a tendency to move downward relative to the guiding ring groove 201. To prevent the slider 133 from moving downward again and entering the locking position 201a, the structure of the guiding ring groove 201 can be improved, so that the slider 133 moves in the width direction of the guiding ring groove 201 away from the locking position 201a. Of course, an external force can also be applied, that is, the second adjusting rod 132 (slider 133) is moved in the width direction of the guiding ring groove 201 away from the locking position 201a through the first elastic member 134. Through the combined action of the first elastic member 134 and the spring-back assembly 120, the slider 133 is moved to the release position 201b at the bottom of the guiding ring groove 201.

[0093] To increase the traveling regularity of the guiding member 121 and the first adjusting rod 131 in the bottom plate 110, thereby increasing the cooperation degree of the self-locking assembly 130, the spring-back assembly 120 and the foot pedal assembly 200. As Figure 3 shown, in some embodiments, a first linear bearing 150 and a second linear bearing 160 are further provided at the bottom plate 110. The first linear bearing 150 is used for installing the guiding member 121, and the second linear bearing 160 is used for installing the first adjusting rod 131.

[0094] Specifically, the first linear bearing 150 is fixed to the bottom plate 110. One end of the guide member 121 facing away from the A plate 210 is installed in the first linear bearing 150, and one end of the elastic return assembly 120 facing away from the A plate 210 is limited in the first linear bearing 150. The second linear bearing 160 is fixed to the bottom plate 110. One end of the first adjusting rod 131 facing away from the second adjusting rod 132 is installed in the second linear bearing 160, and one end of the first elastic member 134 facing away from the second adjusting rod 132 is limited in the second linear bearing 160. Among them, the axis of the first linear bearing 150 is perpendicular to the axis of the second linear bearing 160.

[0095] More specifically, the setting of the first linear bearing 150 restricts the movement freedom of the guide member 121 in the vertical direction, further avoiding the problem that the A plate 210 is prone to skew when moving under the drive of an external force.

[0096] The axis of the second linear bearing 160 is perpendicular to the axis of the first linear bearing 150, that is, the axis of the second linear bearing 160 is along the horizontal direction. The setting of the second linear bearing 160 facilitates the movement of the first adjusting member along its axis, so as to facilitate the slider 133 to adapt to the uneven bottom surface in the guide ring groove 201.

[0097] As Figure 4 shown, in some embodiments, the guide ring groove 201 further has a first high position 201c and a second high position 201d. The locking position 201a is located on the guiding path of the guide ring groove 201 between the first high position 201c and the second high position 201d. The first high position 201c, the locking position 201a and the second high position 201d are located on the side of the guide ring groove 201 close to the A plate 210, and the release position 201b is located on the side of the guide ring groove 201 away from the A plate 210.

[0098] It can be understood that, for the convenience of describing the action process of the self-locking assembly 130, the elastic return assembly 120 and the pedal assembly 200, the transition high points in the guide ring groove 201 are respectively called the first high position 201c and the second high position 201d. The first high position 201c is located on the guiding path of the guide ring groove 201 from the release position 201b to the locking position 201a, and the first high position 201c is located on the side of the guide ring groove 201 close to the A plate 210. The second high position 201d is basically on the same horizontal line as the first high position 201c, but the second high position 201d is located on the guiding path of the guide ring groove 201 from the locking position 201a to the release position 201b.

[0099] When observing the guiding ring groove 201 from the side view of the self-locking component 130, the one-way circular movement of the slider 133 in the guiding ring groove 201 can be clockwise or counterclockwise. Taking the clockwise direction as an example, when stepping on the A plate 210, the slider 133 starts from the release position 201b and reaches the first high position 201c in the clockwise direction. When the A plate 210 is released, under the action of the return component 120 and the first elastic member 134, the slider 133 continues to move clockwise to the locking position 201a, achieving the purpose of keeping the caster 50 in the self-locking state. When stepping on the A plate 210 again, the slider 133 moves upward relative to the guiding ring groove 201, that is, the slider 133 disengages from the locking position 201a. Combining with the pulling of the first elastic member 134 (pulling the slider 133 in the clockwise direction), the slider 133 reaches the second high position 201d. When the A plate 210 is released, under the action of the return component 120 and the first elastic member 134, the slider 133 continues to move clockwise to the release position 201b, achieving the purpose of keeping the caster 50 in the unlocked state.

[0100] Figure 8 It is a front view structural schematic diagram of the guiding ring groove provided by an embodiment of the present application, as Figure 4 and Figure 8 shown. In some embodiments, there is a special-shaped block 230 in the middle of the guiding ring groove 201. The special-shaped block 230 includes a limiting block 231 extending towards the A plate 210. The limiting block 231 is configured to cooperate with the return component 120 to block the slider 133 moving in the guiding ring groove 201, so that the slider 133 is located at the locking position 201a.

[0101] Specifically, for the convenience of describing the shape of the guiding ring groove 201, the middle part of the guiding ring groove 201 formed on the B plate 220 is called the special-shaped block 230, that is, the special-shaped block 230 and the B plate 220 outside the guiding ring groove 201 form the channel of the guiding ring groove 201. After the slider 133 reaches the first high position 201c, due to the existence of the return component 120, the slider 133 will move downward relative to the guiding ring groove 201, and there is a possibility that the slider 133 continues to move along the guiding ring groove 201. To achieve the stability of the slider 133 at the highest position of the guiding ring groove 201, therefore, a limiting block 231 is designed to extend from the special-shaped block 230 towards the A plate 210 direction. The limiting block 231 can effectively block the slider 133 from directly moving from the first high position 201c to the release position 201b. The locking position 201a formed by the limiting block 231 and part of the special-shaped block 230, and cooperating with the return component 120 can keep the slider 133 stably at a higher point of the guiding ring groove 201, that is, when the caster 50 is in the self-locking state, the A plate 210 continuously maintains the downward movement state.

[0102] As Figure 4 and Figure 8As shown, in some embodiments, a step 2011 is formed in the guiding ring groove 201 on the side of the release position 201b, and the step 2011 is located on the moving path of the slider 133 from the locking position 201a to the release position 201b.

[0103] It can be understood that in order to keep the slider 133 moving only clockwise / counterclockwise in the guiding ring groove 201, a step 2011 is provided in the guiding ring groove 201 on one side of the release position 201b. Similarly, when observing the guiding ring groove 201 from the perspective of the self-locking assembly 130 side, taking the clockwise direction as an example for the one-way circular movement of the slider 133 in the guiding ring groove 201, and the step 2011 is formed on the right side of the release position 201b, that is, the depth of the guiding ring groove 201 on the right side of the release position 201b is lower than the depth where the release position 201b is located. This setting can effectively prevent the slider 133 from moving counterclockwise.

[0104] It should be noted that in order to make the movement of the slider 133 smooth in the entire guiding ring groove 201, the bottom surface of the guiding ring groove 201 between the release position 201b and the first high position 201c can be set as a steep slope 201e, that is, the depth of the guiding ring groove 201 gradually becomes shallower from the release position 201b to the first high position 201c, while the bottom surface of the guiding ring groove 201 at the first high position 201c - locking position 201a - second high position 201d - step 2011 is a plane. Of course, it is not necessarily to set the bottom surface of the guiding ring groove 201 between the release position 201b and the first high position 201c as the steep slope 201e. It can also be to set the bottom surface of the guiding ring groove 201 between a certain position starting from the release position 201b and not reaching the first high position 201c as the steep slope 201e. Specifically, it can be designed according to the actual size of the guiding ring groove 201 and the depth difference of the guiding ring groove 201 at the step 2011, and no specific limitation is made here.

[0105] In some embodiments, the braking structure is configured to perform one of the following actions when using the surgical operation console:

[0106] The casters 50 are maintained in the self-locking state: The A plate 210 is forced to move downward, the elastic return assembly 120 stores energy under the movement of the A plate 210, the slider 133 moves relatively in the guiding ring groove 201, and as the A plate 210 continues to move downward, the slider 133 moves from the release position 201b to the first high position 201c; after the A plate 210 loses the external force, driven by the release of the elastic return assembly 120 and the pulling force of the first elastic member 134, the slider 133 moves from the first high position 201c to the locking position 201a.

[0107] The caster 50 is maintained in the unlocked state: The A plate 210 moves downward under an external force, causing the slider 133 to move from the locking position 201a to the second high position 201d; after the external force on the A plate 210 is removed, driven by the force release of the elastic return assembly 120 and the pulling force of the first elastic member 134, the slider 133 moves from the second high position 201d through the step 2011 to the release position 201b.

[0108] Figure 7 is a schematic structural diagram of the self-locking assembly provided by an embodiment of the present application; as Figure 7 shown, in some embodiments, the transmission assembly 300 may include a fixed shaft 310, a first connecting rod 320, a second connecting rod 330, and a prism rod 340. The fixed shaft 310 is hinged to the A plate 210 or the B plate 220; one end of the first connecting rod 320 is hinged to the fixed shaft 310; one end of the second connecting rod 330 is hinged to the other end of the first connecting rod 320; one end of the prism rod 340 is connected to the other end of the second connecting rod 330, and the other end is connected to the locking device on the caster 50. The prism rod 340 is configured to rotate under the transmission of the fixed shaft 310, the first connecting rod 320, and the second connecting rod 330 during the movement of the pedal assembly 200 under an external force.

[0109] It can be understood that the fixed shaft 310, the first connecting rod 320, and the second connecting rod 330 can be understood as a linkage mechanism. During the downward / upward movement of the A plate 210, the linkage mechanism converts the linear movement of the A plate 210 or the B plate 220 into the rotational movement of the driving prism rod 340, that is, during this process, the prism rod 340 only rotates around its axis. When the A plate 210 moves downward by a preset distance, the linkage mechanism drives the prism rod 340 to rotate by a certain angle and transmits it to the locking device inside the caster 50 to achieve the locking of the caster 50. When the A plate 210 moves upward to the initial position, the linkage mechanism drives the prism rod 340 to rotate reversely by a certain angle to the initial state and transmits it to the locking device inside the caster 50 to achieve the effect of retracting the caster 50.

[0110] It should be noted that the cross-section of the prism rod 340 can be triangular, quadrilateral, pentagonal, hexagonal, etc.

[0111] The specific principle of realizing the locking or release of the caster 50 through the rotation of the prism rod 340 can be, as Figure 7 shown, in some embodiments, the prism rod 340 is a hexagonal shaft; the locking device is configured with a hexagonal hole in the caster 50, and one end of the hexagonal shaft away from the second connecting rod 330 is inserted into the hexagonal hole to drive the locking device through the rotation of the hexagonal shaft.

[0112] Specifically, the locking device can be an eccentric structure provided at the caster 50. The eccentric structure is configured with a hexagonal hole, and a hexagonal shaft inserted into the hexagonal hole can drive the eccentric structure to rotate, so that the caster 50 is locked and cannot move, thereby achieving the purpose of locking the caster 50. The structure of the specific locking device can be understood with reference to the prior art and will not be elaborated here.

[0113] In some embodiments, a transition bracket 500 is provided on the chassis 10 between the pedal assembly 200 and the caster 50, so that the hexagonal shaft is inserted into the transition bracket 500 through a bearing.

[0114] Specifically, since the hexagonal shaft is relatively long, to ensure its rotational stability, a transition bracket 500 is provided on the chassis 10 between the caster 50 and the pedal. The hexagonal shaft can be inserted into the transition bracket 500 through a bearing to support the hexagonal shaft.

[0115] Finally, it should be noted that the above embodiments are only used to illustrate the present application, rather than limiting the present application. Although the present application has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications, or equivalent replacements of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should all be covered by the scope of the claims of the present application.
