Abstract
A surgical table which includes a patient support surface 16 for receiving a patient, a vertically-movable support column connected to and supporting the patient support surface, and a pair of four-bar linkages for laterally tilting patient support surface relative to the support column. The support column includes a base that is mounted for vertical movement between a first position in which the surgical table is movable on rollers and a second position wherein the base contacts the floor to lock the position of the surgical table during a procedure. One or more trays may be pivotally connected to the patient support surface and selectively deployed to hold objects such as surgical instruments.
Claims25
A surgical table comprising:
- a patient support surface having a longitudinal axis;
- a frame attached to said patient support surface;
- a base having a support column and a support platform attached to said support column;
- a pair of first link arms, each of said first link arms having a first end pivotally coupled with said support platform and a second end pivotally coupled with said frame, said first link arms, said support platform, and said frame forming a first four-bar linkage mechanism;
- and
- a pair of second link arms spaced along said longitudinal axis from said first link arms, each of said second link arms having a first end pivotally coupled with said support platform and a second end pivotally coupled with said frame, said second link arms, said support platform, and said frame forming a second four-bar linkage mechanism, said first and said second four-bar linkage mechanisms allowing said frame and said patient support surface to tilt transversely relative to said support platform and generally about the longitudinal axis.
A surgical table for supporting a patient and a surgical instrument, comprising:
- a base;
- a patient support surface mounted to said base, said patient support surface having a head section and a longitudinal axis;
- and
- a tray pivotally coupled to said head section of said patient support surface and angularly rotatable about an axis of rotation generally parallel to the longitudinal axis, said tray having a first condition in which angular rotation of said tray about the axis of rotation is inhibited and a second condition in which said tray is rotatable angularly about the axis of rotation, said tray adapted to receive and support the surgical instrument in said first condition.
A surgical table comprising:
- a patient support surface;
- a base having a base frame;
- a support column extending between said base frame and said support surface;
- a carriage coupled for relative movement with said base frame, said carriage including a plurality of spaced-apart rolling members and a pair of yokes each pivotally coupled to said base frame, each of said yokes carrying at least one of said rolling members said carriage;
- and
- a lifting mechanism operative for transferring a lifting force to said linkages sufficient to move said yokes relative to said base frame, said lifting mechanism capable of moving said yokes relative to said base frame between a first position in which said carriage is movable on said rolling members and a second position in which said carriage is not movable on said rolling members .
