Abstract

A surgical operation table has a patient-supporting table top including a main section and an extension section. The extension section is slidable lengthwise of the table top between an extended position in which it extends the length of the table top and a retracted position in which it lies beneath the main section. The extension section can be releasably locked in its extended position.

Claims

1. A surgical examination or operation table comprising a patient-supporting table top including a main section and an extension section, the extension section being slidable lengthwise of the table top between an extended position lengthwise of the table top and a retracted position below the main section, means for releasably locking the extension section in its extended position, the extension section including a carriage portion provided with slide members, complementary slide channels beneath the main section within which the slides are engaged, a swinging portion pivotally mounted on the carriage portion, clamping means for selectively maintaining the swinging portion in a horizontal position or an angular position with respect to the carriage portion, and means at each side of the table top comprising a locking plate pivotally mounted on the extension section and having a locking recess with a lead-in opening facing the direction of movement of the extension section, a co-operating locking pin mounted on the main section in position engageable in the locking recess when the extension section is fully extended, and a spring-loaded push-rod extending lengthwise of the table and being axially moveable against the loading of the spring, whereby to pivot the locking plate and release it from engagement with the locking pin for movement of the extension section selectively into the retracted position or any intermediate position.

2. A table as claimed in claim 1 including stays pivotally mounted on the carriage portion and extending lengthwise beneath the swinging portion, a clamping member carried by the swinging portion and extending transversely thereof, said clamping member having openings in which the stays are slidable, clamping pads inside the clamping member, and a handle at one side of the table, the said handle being rotatable to move the clamping pads into clamping engagement with the stays.

3. A table as claimed in claim 2, wherein the clamping member is a tube extending transversely of the extension section and having openings in which the stays are slidable, a pair of cylindrical clamping pads arranged in the tube, one in contact with each stay, a clamp rod extending between the clamping pads, and a clamp screw rotatable by rotation of the handle so as to move into engagement with one of the stays whereby the stays, clamping pads and clamp rod are compressed into clamping engagement with one another.
