  • Publication number: 20150050099
    Abstract: In various embodiments a frame system for a surgical system may include a plurality of rod structures cross connected through one or more structural members. In some embodiments, the rod structures may each include at least one rod with an interface joint molded over the at least one rod. One or more of the interface joints may include a receiving hole for receiving a structural member to couple at least two of the plurality of rod structures together. One or more surgical components (such as a surgical console) may be received into the frame system. Other components may also be received into the frame system (e.g., an aesthetic skin). The rod structures may also include cross face structural members that are secured to portions of the rod structures through being molded to the rod structures through the interface joints.

  • Patent number: 8910344
    Abstract: In various embodiments, a caster assembly may include a wheel rotatably coupled to a caster housing and a deflector tab pivotably coupled to the caster housing and offset from an outer wheel circumference for use in moving or traversing obstacles encountered during wheel movement. In some embodiments, the deflector tab may include at least one retaining element configured to hold the deflector tab in a pusher position or allow movement of the deflector tab into a ramp position. In the pusher position, the deflector tab may push a mobile obstacle in front of the wheel motion. In the ramp position, the deflector tab may facilitate moving the wheels over a fixed obstacle.

  • Patent number: 8684145
    Abstract: In various embodiments, a braking system may include an actuator, a pawl gear coupled to the actuator, and a wheel gear plate. The braking system may further include a brake pad, an outer wheel coupled to the brake pad, and a spring washer plate configured to press the wheel gear plate against the brake pad such that the wheel gear plate is configured to inhibit rotation of the outer wheel through friction between the wheel gear plate and the brake pad when the pawl gear inhibits rotation of the wheel gear plate. In some embodiments, the braking system may further include a sensor and the actuator may be triggered to actuate the pawl gear in response to signals from the sensor.
