  • Patent number: 11913590
    Abstract: A flexible peristaltic robot with a built-in bidirectional gas pump for self-regulating gas flow. The robot includes a head-end airbag, an extension-retraction airbag, a tail-end airbag, a power module, a control module and a bidirectional gas pump. When there is harmful gas or less gas in the external environment, an additional airbag is provided in the flexible peristaltic robot to form a closed internal circulation of air flow. Otherwise, the robot directly exchanges gas with the external environment to form an open external circulation of air flow. The flexible peristaltic robot can either use multiple bidirectional air pumps or use a single bidirectional air pump and multiple electrically-controlled switches to control the expansion and contraction of the airbags to enable the robot to move forward.

  • Patent number: 11166747
    Abstract: Methods of manipulating cancellous bone within a vertebral body. A steerable assembly is directed through an access cannula such that a deflectable portion of the steerable assembly protrudes from the access cannula to within the vertebral body. The steering instrument is actuated from an operating tension mode in which a tension is placed on the control element of the steering instrument to a slack tension mode in which the tension on the control element is released. The steerable instrument may exert substantially zero lateral force on the deformable conduit in the slack tension mode. The steering instrument is moved relative to the deformable conduit positioned within the vertebral body. The steering instrument is actuated to move the steering instrument from the slack tension mode to the operating tension mode in which the deflectable portion may assume a curved configuration not substantially coaxial with a longitudinal axis of the access cannula.

  • Patent number: 11116484
    Abstract: A lens assembly includes an adjustable lens assembly including a handle. A telescopic tube is inserted at one end of the handle. A threaded rod is disposed inside the handle at an end close to the telescopic tube. An end of the threaded rod away from the telescopic tube penetrates through an outer wall of the handle and is connected to a turn button. An end of the telescopic tube inside the handle is sleeved with a driven gear. A driving gear is embedded in a surface of the handle above the driven gear. The driving gear and the driven gear enable the telescopic tube to rotate, thereby adjusting a direction of an insertion head at one end. The threaded rod and the turn button enable the telescopic rod to move within the handle, thereby adjusting the insertion head at one end to stretch out or draw back.
