Suction fixing device

A suction fixing device configured to be fixed to an associated organic base, the suction fixing device comprising:

• a low-pressure casing configured to apply a low pressure to an associated surface of the associated organic base;
• an attachment device on the low-pressure casing, the attachment device being configured to communicate the low pressure from the low pressure casing to the associated surface of the associated organic base and form a seal between the low pressure casing and the associated surface of the associated organic base thereby securely holding the low-pressure casing to the associated organic base;
• a frame;
• a holding device connected with the frame and configured to secure the fixing device with the associated organic base, the holding device comprising a bone engaging portion with friction enhancing projections separate from the attachment device, the friction enhancing projections being formed by at least one of a pin, a spike, or a friction frame including a roughened or abrasive surface, the friction enhancing projections having tips configured to engage the associated surface of the associated organic base and selectively fix the holding device against lateral movement relative to the associated organic base upon application of the low pressure by the attachment device;
• at least one marker configured for use in computer-aided surgery, the at least one marker being coupled with the frame;
• a first joint element coupled by a first side with a surface of the frame, the first joint element being operable to provide selective relative rotational movement into a selected position between the frame and a second side of the first joint element opposite to the first side of the first joint element;
• and
• a second joint element coupling the second side of the first joint element with the low-pressure casing, the second joint element being operable to provide selective relative translational movement into a selected locked position between the low pressure casing and the second side of the first joint element, the first and second joint elements and the holding device thereby providing for selective changing of a relative locked position between the attachment device and the friction enhancing projections, wherein the relative locked position is locked by the low pressure within the low-pressure casing being selectively communicated to the associated surface of the associated organic base;
• wherein the frame comprises a recess enabling a portion of the low pressure casing and the attachment device carried thereon to pass into the recess and through the frame.

• a valve configured for selective fluid connection between an associated evacuation device and the low pressure casing;
• a flexible connection operatively coupling the low-pressure casing with the valve;
