Medical device capable of properly measuring a center of gravity and capable of preventing overturning of a surgical operation table is provided without performing a significant design change. Medical device S, which includes a plurality of leg portions 20 that lift up a main body 2 from a floor surface and support the main body 2, includes load detection devices 55 that are provided between the main body 2 and the respective leg portions 20, and detect loads in a vertical direction received by the leg portions 20 from the floor surface.

Devices, assemblies, systems, and methods are disclosed for stabilizing a cart. An example cart is a surgical cart having a robotic arm thereon. A stabilizer system may be part of or used with the cart to stabilize the cart at a location. The stabilizer system may include a stabilizer and an actuator. The stabilizer may have a foot and a biaser configured to bias the foot to a retracted position and contribute to an amount of force applied to a floor supporting the cart when the foot is in a deployed position. The actuator acts on the stabilizer to overcome a bias force biasing the stabilizer to the retracted position and cause feet of the stabilizer to contact the floor. Once the feet of the stabilizer contact the floor, a spring of the biaser causes the foot to apply a predetermined force amount to the floor.

An anti-tilt device for a caster that includes a wheel, rotatably mounted in a frame, for rotation about a rotation axis. The anti-tilt device, comprising first and second face plates; first and second flanges extending from opposing edges of said first plate, each of the first and second flanges wrapping beside the first face plate; first and second flanges extending from opposing edges of said second face plate, each of the first and second flange extending beside the first face plate, to prevent rotation of the first and second face plates when mounted to the caster frame; first and second legs extending from the first second face plates, respectively; and a bar, extending between the first and second legs across a tread face of said caster wheel when mounted to said frame, at a defined angle of the tread face, as measured from a vertical axis extending through said rotation axis, when said caster is level. Each of said first and second legs includes a defined bend to place said bar at said defined angle.

The invention relates to a stand base (10) for microscopes, which encompasses a stand base body (12) on which multiple rollers (14 to 20) for displacing the stand base (10) are fastened. The stand base (10) furthermore has a braking system (40) to prevent displacement of the stand base (10), the braking system encompassing at least two braking feet (44, 46).

A movable umbrella base comprises a housing (1), a wheel frame (2) disposed under the bottom of the housing (1), at least three wheels (3) connected at intervals to the wheel frame (2) and located partially under the wheel frame (2), a plurality of air bags (4) located inside a space defined by the wheel frame (2) and the housing (1), and a plurality of elastic members (6) limit displacement of the wheel frame (2) and the wheels (3) from the housing (1); when the air bags (4) are inflated, the housing (1) is lifted up relative to the wheel frame (2) and the wheels (3) from the ground; when the air bags (4) are deflated, the housing (1) is lowered relative to the wheel frame (2) and the wheels (3) and contacts the ground. The umbrella base can be moved by the air bags (4), the whole operation process is easier, and it saves more time and effort.

Provided are a truckle structure and a cabinet. The truckle structure comprises: a truckle and a support, wherein the truckle includes a mounting base and a wheel rotatably mounted on the mounting base; the support is composed of a mounting portion located at a lower middle position as well as two connecting portions respectively located on two sides of the mounting portion; the two connecting portions are formed in a manner that the left side and the right side of the mounting portion are upwards bent towards the middle, the support is rotatably connected to the mounting base through the two connecting portions, and the mounting base is located between the two connecting portions; and a mounting hole is formed in the mounting portion, center of the mounting hole and center of gravity of the truckle are on a same straight line, and center of gravity of the support deviates from the straight line. The truckle structure can be directly mounted on the ground and is firmer and more durable.

The umbrella base can be moved by the air bags (4), the whole operation process is easier, and it saves more time and effort.

A safety walker having a frame with a set of spherical caster wheels connected to the lower portion of the frame to provide omnidirectional movement with reduced force. A braking system is provided, where when a weight exceeding a threshold weight is applied to the frame, the brake is engaged to inhibit movement of the walker on the ground. The brake may use a mechanism in which each spherical caster wheel is retractably mounted within a lower end of a corresponding leg of the frame. Each spherical wheel is spring-loaded to urge the spherical wheel downward from the lower end of the corresponding leg. As weight is applied to the frame, the spherical caster wheel is pushed into the lower end of the leg, allowing the lower end of the leg to contact the ground surface and maintain stationary contact between the leg and the ground surface.

Included is a stabilizer wheel assembly that may assist in stabilizing a medical device during a medical procedure. A medical device may comprise a body; and a plurality of stabilizer wheel assemblies coupled to the body, wherein the stabilizer wheel assemblies each comprise a motor assembly and a stabilization leg, wherein the motor assembly is configured to drive the stabilization leg onto a contact surface to stabilize the body.
