摘要:
A particulate material comprises hollow or cup-shaped ceramic microspheres having a diameter in the range of from 5 to 200 microns, the microspheres being formed from a base material comprising greater than 70% by weight of yttria or another yttrium-containing compound together with one or more compounds selected from the group consisting of alumina or another aluminium-containing compound, zirconia or another zirconium-containing compound, and silica or another silicon-containing compound. The particulate material may comprise a beta-radiation emitting radionuclide ytrrium-90, and be used in selective internal radiation therapy (SIRT) of various forms of cancer and tumors.
摘要:
A clamping device (10) for clampingly interconnecting a first elongate element (17) and a second elongate element (15). The clamping device (10) comprises a shaft (19), and a first clamping member (21) mounted on the shaft. The first clamping member (21) has first and second clamping sections (31, 32) between which the first elongate element (17) can be slidingly received and clampingly engaged. An aperture (73) is provided in the shaft (19) adjacent the second section (32) of the first clamping member (21) to slidingly receive the second elongate member (15). A second clamping member (22) is mounted on the shaft (19) and is displaceable therealong for clamping the second elongate element (15) between the first clamping member (21) and the second clamping member (22). A cam locking mechanism (23) is operably connected to the shaft (19) for selectively moving the clamping device between clamping and non-clamping conditions. In moving the clamping device (10) into the clamping condition, the cam locking mechanism (23) causes displacement of the second clamping member (22) along the shaft (19) such that the second elongate element (15) is clampingly engaged between the first clamping member (21) and the second clamping member (22).

摘要:
The present invention provides a retractor assembly capable of supporting at least a tissue engaging member in a manner allowing self alignment of the member subject to the pull force of the tissue engaged by the member. The retractor assembly comprises: (i) a frame member which supports a support member; (ii) at least one tissue engaging member which possesses at least a mounting arrangement which is capable of releasably engaging the support member; and (iii) a locking member which is capable of releasably engaging the tissue engaging member with the frame member and the support member to hold the tissue engaging member(s) in a substantially immovable position.

摘要:
A ball and socket interconnection capable of use in surgical retractor systems comprising a ball member and a socket member, the socket member defining an entry and being adapted to releasably receive the ball member such that when the ball member is received in the socket member it is capable of pivotal and rotational movement within the socket, the ball member having two spherical end surfaces between which is located an intermediate section, the spherical end surfaces having a radius of curvature greater than the radius of curvature of the entry and the intermediate section having a radius of curvature less than the radius of curvature of the entry, whereby the intermediate section renders the ball member releasably receivable in the socket member.
