A bone clamp for attachment to a bone includes a first lever and a second lever that are connected to each other by a connection, a sliding block, and a screw. The first lever has a first lever arm and a second lever arm, and the second lever has a third lever arm and a fourth lever arm, the second ends of which are configured to contact the bone. The sliding block is slidably attached to the first lever arm, the screw is pivotably mounted in the sliding block, the first lever arm includes a threaded surface for engaging with the screw mounted in the sliding block, and the sliding block includes a sliding surface on which the third lever arm slides such that the second ends of the levers approach each other when the sliding block moves along the first lever arm.

A reference foil comprises an unsymmetric marker foil device which advantageously includes spatially separated pieces of a marker material foil in unsymmetric arrangement and/or at least one unsymmetric integral piece of the marker material foil. The reference foil and a carrier device for the same may be used for example in image-guided surgery.

Disposable and radiolucent reference array for optical tracking

The invention relates to a fixation system for attaching a medical image registration matrix () to a patient holder () which is to be covered by a sterile drape (), wherein the fixation system comprises at least one fixation set (L, R) comprising a lower part () which is adapted to be connected to the patient holder () and an upper part () which is adapted to be connected to the registration matrix () or one of its supporting elements, wherein: the lower and upper parts () can be connected to each other by a connector () which does not penetrate the drape (); the lower and upper parts () comprise mutually engageable profiled interfaces () which are formed so as to accommodate and clamp the drape () between them; and wherein the profiled interfaces () fit together over a continuous zone of engagement.

A medical head holder includes at least two opposing engagement members configured to engage the head of a patient, a frame, connector and coupling members, and a force applicator. The frame includes first and second frame sections which are displaceably coupled with each other, wherein each frame section supports at least one of the engagement members. The connecting member guides the first and second frame sections for displacement relative to each other, and selectively detachably fixes the frame sections with each other. The coupling member is selectively fixed to the second frame section and displaceably couples the second engagement member with the second frame section. The force applicator is detachably coupled to the second frame section and acts on the coupling member so as to cause the second engagement member to be displaced and/or fixed relative to the second frame section.

A connector for attaching a reference array in a fixed positional relationship with respect to a patient to be covered by a sterile drape in an attachment area, includes a support to be situated below the drape and a clamping element which is to be situated above the drape and can directly or indirectly hold the reference array or a reference array adaptor, wherein the clamping element clamps the support, with the drape caught between the two, by at least two distinct clamps which clamp the support from at least partly opposing directions in such a way that the positional shift in the clamping element as a result of clamping the drape at the clamping position is compensated for, such that its overall positional shift is substantially zero. A method attaching a reference array in a fixed positional relationship relative to a patient above a sterile drape is also provided.

Drape-clamping reference array connector

The invention relates to a connector () for attaching a reference array () in a fixed positional relationship with respect to a patient, wherein the patient is to be covered by a sterile drape in the attachment area, the connector () comprising: a support () which is to be situated below the drape (); and a clamping element () which is to be situated above the drape and can directly or indirectly hold the reference array () or a reference array adaptor, wherein the clamping element () clamps the support (), with the drape () caught between the two, by means of at least two distinct clamps () which clamp the support () from at least partly opposing directions in such a way that the positional shift in the clamping element () as a result of clamping the drape () at the clamping position is compensated for, such that its overall positional shift is substantially zero. The invention also relates to a connector arrangement () comprising such a connector () and to a method for attaching a reference array () in a fixed positional relationship with respect to a patient.

A radiolucent fastening device for fastening a reference device to a body for computer-assisted surgery, wherein a part of the fastening device is made from an unsubstituted carbon fiber reinforced polyether compound, a monosubstituted carbon fiber reinforced polyether compound or a multisubstituted carbon fiber reinforced polyether compound.

Radiolucent reference for computer-assisted surgery

The present application relates to an x-ray marker device comprising an arrangement of x-ray markers, wherein the arrangement defines straight lines which are referred to as device straight lines, wherein at least some of the device straight lines, which are referred to as pyramid straight lines, comprise portions which define edges of at least one pyramid.
