Removable barrier devices (e.g., sleeves) for covering medical scanning devices to reduce the chance of cross-contamination between patients and/or to protect the scanning devices from physical damage. The barrier device can include a cover that has an integrated window for passing optical signals between the scanning device and an external environment. The cover can include a sleeve that covers a handle portion of the scanning device to prevent contamination of the handle from a user's hand or glove. The cover and sleeve may both be formed of the same flexible material, or the cover may be rigid to maintain the window in a fixed position and the sleeve may be flexible to allow a user to activate a button or touchpad on the handle. An interface region between the cover and sleeve may provide a hermetic seal. The window may include a nanostructured antireflective material to limit internal reflections.

A surgical robot drape for providing a sterile barrier over a portion of a surgical robot, the drape comprising a plurality of accessibility portions spaced apart from one another in the drape for providing selective access through the drape at the respective locations of the accessibility portions, each accessibility portion comprising a separation line joining neighbouring portions of the drape and being configured to permit the separation of the neighbouring portions of the drape about the separation line for allowing access through an opening thereby formed in the drape.

An ultrasound apparatus of a body cavity insertable type includes: a handpiece; a supporting rod which is elongated from the handpiece; an ultrasound probe which is connected to the supporting rod and is configured to be able to be inserted in the body cavity; and a sealing cover which is separably coupled to the ultrasound probe to at least partially surround the ultrasound probe in a longitudinal direction from a distal end thereof. The ultrasound probe includes: a piezoelectric element; and a housing to which the piezoelectric element is mounted. An end of the housing is connected to the supporting, and the housing is provided with an ultrasound passing hole which is disposed outside the supporting rod. The sealing cover has an ultrasound passing window which is formed at a position corresponding to the ultrasound passing hole.

A motion feedthrough for a surgical drape, the motion feedthrough comprising a drive transfer element comprising a first portion and a second portion, the first portion being releasably engageable with a portion of a robot arm and the second portion being releasably engageable with a portion of an instrument, the drive transfer element being movable relative to a bulk portion of the drape so as to transfer drive between the robot arm and the instrument.

A surgical drape for covering at least a portion of a surgical robot arm, the arm comprising at least one drive assembly interface element for transferring drive between the arm and an instrument engageable with the arm, the drape comprising an interface portion locatable between the arm and the instrument when the instrument is engaged with the arm; and a bulk portion encompassing the interface portion; the interface portion and the bulk portion being adjacent one another, the interface portion comprising one or more of a material or configuration having a lower modulus than that of the bulk portion in at least one direction, and a movable portion, the movable portion being movable relative to the bulk portion, so as to permit repeatable movement of a portion of the interface portion relative to the bulk portion.

A system and method for reducing the risk of contamination of interior regions of a needle guide which is disposed on an endocavity transducer, which system includes an elastic membrane forming a pocket which covers a needle exit hole in the needle guide. The pocket is disposed on a sheath which is both; disposed around the endocavity transducer and between the endocavity transducer and the needle guide.

An introducer sheath assembly including an introducer sheath and a protective sheath. The introducer sheath includes a hub having a proximal end and a distal end, and a tubular sheath projecting from the distal end of the hub. The protective sheath has a proximal end and a distal end. The distal end of the protective sheath is attached to the hub adjacent to the proximal end of the hub. The protective sheath is configurable between an undeployed state wherein the proximal end of the protective sheath is adjacent to the hub, and a deployed state wherein the proximal end of the protective sheath is away from the hub.
