Abstract: The invention relates to a hoist mechanism (20) intended primarily, but not exclusively, for moving a motor driven wheelchair or scooter into and/or out of the load carrying space of a vehicle. The hoist mechanism (20) comprises a lifting arm having, at least in part, a generally U-shaped cross section, and an actuator (28). A mounting point (56) for the actuator (28) is provided within the generally U-shaped cross section. The invention also relates to a stepless adjustment system suitable for use in such a hoist mechanism (20). The adjustment system comprises an inner section (34) received within an outer section (24) in a telescoping arrangement. The outer section (24) comprises first and second body portions (44A, 44B) provided with features for engaging corresponding features (48A, 48B) provided on the inner section (34).

Abstract: Disclosed is a hoist mechanism comprising a lifting arm wherein: when the lifting arm is in a fully raised position, a projecting upper end section of a major part of the lifting arm extends substantially horizontally; an effective length of the projecting upper end section is made variable by the provision of an extension element adjustably fixed to it; and the lifting arm is variable in upstanding height by a provision of a lower end section slidably connected to the major part of the lifting arm, wherein both length and height variations are made by stepless adjustments.

Abstract: A surgical apparatus (10) comprises a manipulating portion (12), a delivery portion (14) spaced longitudinally from the manipulating portion, and a connecting portion (16) connecting the manipulating portion to the delivery portion. The connecting portion extends laterally from the delivery portion. The surgical apparatus further includes a securing arrangement (28) for releasably securing a surgical member to the delivery portion.

Abstract: A cutting device (11) comprises a cutting head (14) of substantially circular cross-section, the cutting head having a main axis (X), and a distal cutting edge (23). The cutting edge has a first cutter. The cutting head (14) has a cutting portion (21) and a second cutter extending inwardly of the cutting portion. The second cutter (26) comprises a plurality of spaced cutting members (32) arranged in an array around the main axis. Each cutting member has a substantially planar cutting surface (32A) extending substantially parallel to, and offset from, the main axis.

Abstract: A surgical apparatus (10) comprises a support member (12), and first and second mounting arrangements (26, 28) for mounting respective first and second retractors (22, 24) mounted on the support member. The mounting arrangements are mounted on the support member, and at least the first mounting arrangement is movable towards and away from the second mounting arrangement.
