摘要： A flexible cannula device and delivery system for use in arthroscopic surgery. The delivery system engages the flexible cannula from the inside near the distal tip and pushes it into the surgical portal, essentially pulling the proximal portion of the cannula from the distal tip while being pushed from the proximal end with the specialized driver. The delivery system provides for single point engagement at the distal tip as well as a multiplicity of engagement points along the length of the system.

摘要： The present disclosure provides devices and methods for insufflating abdomens of subjects under direct visualization. Such devices and methods, in some implementations, include features for cleaning the devices, and certain implementations of the methods permit procedures wherein it is not necessary to use a typical obturator to place a cannula, resulting in safer procedures.

摘要： Embodiments disclosed herein are directed to apparatus and methods for a stepped needle for an intraosseous device that uses the outer surface of the bone cortex as a reference point. Since the thickness of the bone cortex does not vary significantly between patients, the accuracy of needle placement can be improved. The device includes a needle with a stepped increase in outer diameter disposed along the needle shaft. The abrupt change in outer diameter provides a substantial increase in insertion force. In embodiments, the stepped increase prevents any further insertion into the bone cortex. Embodiments include a tapered needle lumen for medullary access confirmation and an overtube that is rotatably and slidably engaged to protect surrounding tissues and prevent needle stick injuries. Further, a needle hub can be rotatable or slidable, and can transition an overtube to an extended position to prevent accidental needle stick injuries.

摘要： Introduced here is an ingestible device that can comprise a capsule, an intervention tool, and a processor configured to controllably employ the intervention tool to manipulate structures in a living body. The ingestible device may further comprise a camera that is configured to generate images of various in vivo environments as the ingestible device traverses the living body. These images may be wirelessly transmitted to an electronic device located outside of the living body to enable greater control over the intervention tool.

摘要： A percutaneous introducer, particularly for flexible drainage tubes and with various profiles, includes a main body, the main body having a longitudinally extended tubular element arranged in the distal portion of the main body. The tubular element has a terminal arranged at the distal end of the tubular element. The percutaneous introducer has a sliding body which includes a longitudinally extended obturator arranged in the distal portion of the sliding body, the obturator being inserted and being movable longitudinally within the tubular element of the main body. The obturator includes a cutting blade arranged and fixed at the distal end of the obturator. The percutaneous introducer includes a return and positioning spring adapted to return the cutting blade to a retracted position within its seat, following the controlled exit of the cutting blade through a passage slot arranged in the terminal of the tubular element.

摘要： The surgical robotic access system provides access for robotic instruments and/or actuators including the introduction, operation and withdrawal of such robotic manipulators into a body cavity without permitting the escape of pressurized fluid or gas. The surgical robotic access system also provides a multi-faceted range of movement without touching or effecting pressure on the opening in the patient's body cavity.

摘要： A puncturing device and an anchoring device, the puncturing device including: a puncturing needle, an inflatable anchoring balloon, and a catheter which passes through a proximal end and distal end of the anchoring balloon, the puncturing needle being movably accommodated within the catheter; in a filled state, a central area of an end portion of the distal end of the anchoring balloon is depressed towards the proximal end to form a depressed area, and a distal end of the catheter is located within the depressed area. The anchoring device includes the anchoring balloon and the catheter. The puncturing device may improve the accuracy and success rate of puncturing, and after puncturing is complete, an expansion balloon may be transported along a guide wire to expand a puncturing opening by simply withdrawing the puncturing needle and a push rod.

摘要： A vascular closure device assembly, comprises a sheath comprising: a sheath main body defining a channel therethrough, a sheath engagement portion, and a sheath mounting portion located at a proximal end of the sheath main body. The assembly comprises a housing within which the sheath mounting portion is secured such that the sheath is rotatable relative to the housing, and such that the housing inhibits axial displacement of the sheath relative to the housing. The assembly also includes a dilator comprising a dilator main body, and a dilator engagement portion extending from the dilator main body towards the sheath. The dilator engagement portion is configured to engage the sheath engagement portion such that axial displacement of the dilator relative to the sheath causes the sheath to rotate relative to the housing, and wherein the housing is configured to inhibit axial displacement of the sheath during rotation.

摘要： An infusion set includes a base (221) and a flexible catheter (242) movable from a first catheter position disposed substantially entirely within the base (221) to a second catheter position in which a free end of the catheter (242) is disposed externally of the base (221). An introducer needle (234) is located within the catheter (242) and is movable between a first introducer needle position disposed substantially entirely within the base (221) and a second introducer needle position in which a free end of the introducer needle (234) is disposed externally of the base (221). A spring (281) is activated to move the catheter (242) from the first to the second catheter position and the introducer needle (234) from the first to the second introducer needle position to facilitate insertion of the catheter (242). The introducer needle (234) is thereafter moved by the spring (281) back to the first introducer needle position to store the introducer needle (234) within the base (221) with the free end of the catheter (242) remaining disposed externally of the base (221).
