Abstract:
1. 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 defining a sealing surface configured to form a seal between the low-pressure casing and the associated surface of the associated organic base to selectively communicate the low pressure within the low-pressure casing to the associated surface of the associated organic base thereby securely holding the low-pressure casing to the associated organic base; a holding device 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 being 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 holding device; a first joint element coupled by a first side with a surface of the holding device, the first joint element being operable to provide selective relative rotational movement into a selected position between the holding device 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.
