  • Patent number: 10758267
    Abstract: A trocar assembly includes a cannula having a proximal portion and an opposing distal portion. The distal portion is configured to extend into a patient body. The cannula defines an access channel between the proximal portion and the distal portion, wherein the access channel is configured to receive a scope such that the scope can be maneuvered through the access channel to a location within the patient body. A cleaning element at the distal portion is configured to contact at least a distal end of the scope.

  • Patent number: 10751085
    Abstract: A trocar assembly with an integrated scope-cleaning structure may have a proximal portion configured for accessibility by a user and a cannula extending distally from the proximal portion and configured to extend distally into a patient body, where the cannula is further configured to receive a distal end of a scope such that the scope can be maneuvered through the cannula to a location within the patient body. A cleaning element may be included, where the proximal portion includes a housing, where the cleaning element is substantially located within the housing.

  • Publication number: 20200008663
    Abstract: The present disclosure relates to a trocar assembly with an integrated scope-cleaning structure. The trocar assembly may include a housing defining boundaries of a chamber with (a) a proximal opening configured to receive a distal end of a scope, and (b) a distal opening in fluid and mechanical communication with a trocar cannula. The trocar assembly may further include a cleaning element located at least partially between the proximal opening and the distal opening, where the cleaning element is movable with respect to the housing from at least a first setting where a first portion of the cleaning element may be in a first location and may form a first cleaning surface within the chamber, the first cleaning surface configured to remove debris from a distal end of the scope when the distal end of the scope contacts the first portion of the cleaning element.

  • Patent number: 10368905
    Abstract: The present disclosure relates to a housing for a laparoscopic trocar assembly with an integrated scope-cleaning structure. The housing may include a shell forming a wall portion of a chamber and a cleaning element forming at least a portion of an internal surface of the chamber, the cleaning element configured to remove debris from a distal end of a scope upon contact between the cleaning element and the distal end of the scope. The cleaning element may be movable with respect to the shell of the housing in response to an input force upon the shell that moves a portion of the shell and a portion of the cleaning element between a default state and a displaced state.

  • Patent number: 4742898
    Abstract: A shock absorber comprising a housing assembly including an elongated cavity for containing hydraulic fluid, an annular cavity surrounding the elongated cavity, a piston assembly including a head slidably received by the elongated cavity and a rod joined to the head for movement therewith, a compressible bladder containing gas under pressure positioned within the annular cavity, and a plurality of orifices defined within the housing assembly through which the elongated and annular cavities communicate with one another. The rod extends through the housing assembly and is movable with the piston head between extended and retracted conditions. The bladder is positioned within the annular cavity so as to extend along at least a portion of the annular cavity and leave uncovered a portion of the inner wall. The plurality of orifices are arranged in a pattern along the uncovered portion of the inner wall.

  • Patent number: 3991863
    Abstract: A shock absorber having a piston movable against a head of fluid under externally applied loads transmitted through a hollow piston rod. The piston has a valve surrounding a hollow metering pin defining a primary orifice and an auxiliary orifice, adjustable in size, is formed in the housing for augmenting the primary orifice area. The hollow metering pin provides a passage establishing communication between the auxiliary orifice and an accumulating reservoir located within the hollow piston rod. A fluid circulating system is provided for returning displaced fluid and for dissipating the heat generated in such fluid.
