摘要:
An interface device and method for interfacing instruments to a medical procedure simulation system serve to interface peripherals in the form of mock medical instruments to the medical procedure simulation system computer to enable simulation of medical procedures. The interface device includes a housing having a mock bodily region of interest to facilitate insertion of a mock instrument, such as an endoscope tube, into the interface device. The mock bodily region of interest may be pivotable to simulate various patient orientations. The instrument is engaged by a capture mechanism in order to measure rotational and translational motion of the instrument. An actuator is disposed within the interface device to provide force feedback to the instrument. The measured motion is provided to the computer system to reflect instrument motion on the display during the simulation. Alternatively, the interface device may be configured to accommodate instrument assemblies having a plurality of nested instruments (e.g., sheath, catheter and wire), whereby the interface device individually grasps, measures manipulation of and provides force feedback to the nested instruments. In addition, the interface device may be configured to simultaneously accommodate a plurality of independently inserted instruments.

摘要:
A medical instrument includes a needle nozzle that accepts a needle cam. A needle hub assembly includes a needle hub and a needle cannula, and when registration ribs of the needle hub are fitted between respective registration ribs of the needle cam, the needle is thereby fitted onto the medical instrument.

A nasal mask assembly having a nare seal for enclosing the nares of a patient and a pair of lateral support members for engaging the cheekbones of a patient and supporting the nasal mask assembly. An associated headgear assembly constructed of semi-rigid members are selectively interconnected for defining a headgear. The nasal mask assembly is interconnected with depending arms of the headgear assembly by contact connectors enabling the nasal mask to be adjusted linearly and angularly with respect to the headgear assembly.

A peelable sheath includes a sheath formed of a flexible tube having a pair of separation lines arranged longitudinally on radially opposite sides of the tube to form a pair of peelable sheath portions, and a hub connector bonded to the proximal end of the sheath. A pair of wings are bonded to the proximal end of the sheath to faciliate separation. The hub connector and sheath are bonded by a web extending axially from a shoulder of the hub connector and including a pair of web tabs arranged on radially opposite sides of the hub connector. The web tabs are bonded to the sheath across respective separation lines, thereby preventing premature separation of the peelable sheath portions. The web also includes a pair of web support struts, arranged on radially opposite sides of the hub and rotated about 90.degree. relative to the web tabs, that are bonded to the respective wings to prevent premature separation of the hub connector from the sheath.
摘要:
A dispenser having a housing for dispensing candies therefrom and having a rotatable raceway therein with a plurality of turntables disposed within the housing and on the raceway, with each of the turntables including a compartment sized to accommodate a candy to be dispensed, and a drive motor for driving the raceway and coupled to the turntables for rotating the turntables and for revolving the turntables within the housing to transport the candies to a dispensing station.
摘要:
A novel surgical instrument suitable for insertion and assembly of surgical fasteners, such as multi-ring compression devices, for circular anastomosis of tubular or hollow organ tissue sections, including a body having means to support and align the rings, means for clamping the rings around the free ends of the tissue sections, means for coring away excess clamped tissue and the centers of the rings, separate means for releasing the clamped rings from the instrument and dwell means to delay releasing the rings until after the coring operation is complete. The dwell means consists of an external cup containing separate and coaxial elements for the coring means and the releasing means which are provided with a series of recesses and a plurality of shifter keys to separate the operation of coring from the separate operation of releasing the assembled multi-ring compression device from the instrument. The instrument may additionally include means for detaching a portion of the support means to facilitate installation and alignment, a safety to ensure safe operation and various knife blade profiles. Additionally, the surgical instrument may be provided with a longitudinal bore extending throughout the length of the instrument for receipt of accessory instruments therethrough. Further, lockout means may be provided to block the coring means until the rings have been clamped around the tissue sections.
