摘要： A disposable seal assembly for use with a reusable cannula, where the seal assembly is designed for use with the cannula during a single medical procedure and the cannula is designed for multiple uses (each time with a different seal assembly) during a number of medical procedures. The seal assembly includes both a flapper valve fluid seal (for sealing the cannula when no medical instrument is inserted through the seal assembly) and at least one instrument seal (for sealing the cannula when a medical instrument is inserted through the seal assembly). Preferably, the seal assembly has a body with a flange which can be snapped onto the cannula before use, and readily removed after use. Also preferably, the flapper valve has an over-centered hinge. In other embodiments, the invention is a seal assembly which includes at least one double instrument seal including a sacrificial flange and a sealing flange, and optionally also a flapper valve. The sealing flange seals the cannula when a medical instrument is inserted through the seal assembly even when the sacrificial flange has been cut during insertion of the instrument. In other embodiments, the invention is a system including a reusable cannula, and a disposable seal assembly of any of the described types which can be snapped onto the cannula before use and readily removed after use.
摘要翻译：一种与可重复使用的插管一起使用的一次性密封组件，其中密封组件设计成在单个医疗过程期间与套管一起使用，并且套管被设计为在多个医疗程序期间的多次使用（每次具有不同的密封组件）。密封组件包括挡板阀流体密封件（当没有医疗器械通过密封组件插入时用于密封插管）和至少一个仪器密封件（当医疗器械通过密封组件插入时用于密封套管）。优选地，密封组件具有带法兰的主体，该凸缘可以在使用之前被卡扣在套管上，并且在使用后容易地移除。还优选地，挡板阀具有过中心的铰链。在其他实施例中，本发明是一种密封组件，其包括至少一个双重仪器密封件，其包括牺牲凸缘和密封凸缘，以及可选地还有挡板阀。当医疗器械插入密封组件时，密封法兰密封套管，即使在插入仪器期间牺牲法兰被切割时。在其他实施例中，本发明是一种包括可重复使用的套管和任何所述类型的一次性密封组件的系统，其可以在使用之前被卡扣到套管上并且在使用后容易地移除。

摘要： A disposable seal assembly for use with a reusable cannula preferably includes a flapper valve fluid seal and at least one instrument seal. The instrument seal has a sacrificial flange and a sealing flange that protrude from an inner baffle connected to the assembly's main body by a flexible outer baffle, and at least one elastomeric rib extending between the inner baffle and the body to prevent inversion of the inner baffle. Preferably, a surface of the sacrificial flange is configured to prevent the flanges from sticking together during use. An adaptor, tethered to the assembly's main body, has a central channel with an hourglass profile, a concave distal flange, distal bumpers for preventing the adaptor from translating too far into the main body, and a grip portion shaped to allow a user conveniently to separate the adaptor from the main body. Other aspects include systems with a reusable cannula, and methods for using such systems.

摘要： A tissue removal system comprises a rotatable burr element located within a distal housing and a burr opening. The burr opening is located about a distal surface and side surface of the distal housing. The distal housing is configured to bend or pivot with respect to a proximal housing. The proximal housing comprises an auger hole configured to draw fluid and particulate matter for transport proximally along the length of the tissue removal system. A linkage assembly attaches a drive shaft of the tissue removal assembly to the rotatable burr element to permit rotation of the rotatable burr element when the distal housing is bent or pivoted.

摘要： A bedcovering with an expandable center extension of fabric for accommodating an animal pet while sleeping. The bedcovering accommodates a pet, such as a dog, in sleeping on the bed without depriving human occupants of bed coverings. The bedcovering is comprised of two side panels affixed longitudinally to a central panel extension. Further, on each side panel, proximal to the center panel extension is a longitudinal attachment means. The two attachment means mate together to allow the center extension to be collapsed and hidden beneath the two side panels, giving the appearance of a standard bed covering. Non-pet owners who desire extended bed coverings may also use the present invention.

摘要： A chromatography column and method of maintenance is described which does not require the use of a hoist or crane for disassembly. The method provides improved operator safety by reducing the need for the operator to work below a suspended or supported load within the column. Furthermore, the removal or replacement of column components is facilitated by providing access to the interior of the column and by the provision of a handling device.
