Abstract: The invention described herein generally pertains to a composition that includes a silyl-terminated polymer having silyl groups linked to a polymer backbone via triazole. The silyl-terminated polymer is a reaction product of a functionalized polymer backbone and a functionalized silane. The polymer backbone includes a first functional group, which may be one of an azide or an alkyne. The functionalized silane includes a second functional group may also be one of an azide or an alkyne, but is also different from the first functional group. The functionalized polymer backbone is reacted with the functionalized silane in the presence of a metal catalyst.

Abstract: A reinforcement implant comprises a cantilever part for spanning a resected area of a lamina and an anchoring part at opposite ends of the cantilever part. The first anchoring part has a pressure surface for bearing on the spinous process of the vertebra, and the second anchoring part has a transverse thrust surface for bearing on an outer face of the lamina. The pressure surface and the transverse thrust surface enclose an obtuse angle. An anti-shear device (e.g., a facet screw) is arranged on the transverse thrust surface, and one edge of the transverse thrust surface is adjoined by a load-bearing area of the cantilever part. The implant can thus be mounted in place from outside without needing to be pushed with a load-bearing action into the resected area. The resection surfaces on the lamina are free of loads, such that unevenness does not cause problems.

Abstract: An implantation instrument for an expandable intervertebral fusion implant that includes a base piece and a cover piece that are configured to bear on a facing end plate of one of two adjacent vertebrae, the cover piece being adjustable in height with respect to the base piece, and a ratchet mechanism being provided between the base piece and the cover piece to effect a stepped adjustment of height and secure an adopted height again reversal, the implantation instrument being configured for expanding the intervertebral fusion implant and comprising a force measurer that interacts with a displacement measurer to indicate an expansion attained by a particular actuating force.

Abstract: A fixing arrangement comprises a retaining element and a clamping sleeve which receives a bone screw. The bone screw has a head and a secondary thread and is pivotally mounted in the clamping sleeve. The clamping sleeve has a radially protruding section on the outer casing of the clamping sleeve and at least one track of a clamping thread, which complements the secondary thread, in the interior of the clamping sleeve. In the unclamped state, a free path is formed by a clearance on the clamping sleeve. A protruding section engages into an opening on the receiving seat in a formfitting manner, and the thickened section is shaped to expand towards the rear in the form of a cone. The cone angle is selected such that the free path divided by the tangent of the half-cone angle corresponds to 0.5 to 2.5 times the thread pitch of the secondary thread.

Abstract: An intervertebral fusion implant for the fusion of two adjacent vertebrae includes an elongate, adjustable support body, of which the lower and upper cover surfaces are designed to bear on end-plates of the adjacent vertebrae, wherein a side bracket is provided, which is pivotable laterally about a hinge, and of which the bottom face and top face are designed to bear on the end-plates. The support body furthermore is provided, on the cover surface thereof, with a lifting plate which, by means of a lifting mechanism, is adjustable in height between a retracted state and a raised state in which the lifting plate forms a bearing for one of the end-plates. Thereby, both adaptions of width as well as of height are achieved.

Abstract: An intervertebral fusion implant for fusion of adjacent vertebrae, includes a main body having a first leg, a second leg, and an intermediate articulated joint, a pivoting blade is rotatably attached to the first leg, a guiding trough that includes two lateral side walls and two end-faces, one being stationary and one being movable and formed by a traveller movable along the guiding trough to vary its distance to the stationary end-face, the traveller being rotatably attached to the other end of the pivoting blade, wherein an attachment device is provided at the stationary end-face, and a second attachment device is provided at the traveller, which includes an aperture for passage of the holding instrument, wherein a lifting mechanism includes a lifting plate adjustable between retracted and raised states, the lifting plate being spaced from a top surface of the legs and forming a bearing for an adjacent vertebrae end-plate.

Abstract: A handheld surgical tool includes a handle, an instrument shaft, and a navigation device, which includes at least one sensor unit for sensing positional data, a computing unit configured to determine a position in space based on signals of the sensor unit, at least one set key and a position memory configured to store a data set for a position upon activation of the at least one set key. A comparator is operatively connected to the position memory for comparing an actual position against a stored position in at least two different operation modes and for generation of a deviation signal, wherein operation modes differ in that a first mode is configured for a reduced comparison only which lacks at least one spatial dimension. A feedback device is provided supplied with the deviation signal and being configured to indicate direction and preferably magnitude of any deviation.

Abstract: The invention relates to an intervertebral fusion implant for fusing two adjacent vertebrae (9, 9?), comprising a base piece (2) and a top piece (3) which in each case are designed to come to rest against a facing end plate (92) of one of the adjacent vertebrae (9, 9?), wherein the top piece (3) is vertically adjustable relative to the base piece (2), wherein a ratchet device (4), which effects a vertical adjustment in steps and secures a set height against reversion, is provided between the base piece (2) and the top piece (3). Thus a defined expansion can be achieved which is dependent upon the number of actuations. Precise control over the state of expansion is enabled in a purely haptic manner. Furthermore, implantation instruments are provided which are configured as parallel spreaders and have a stop as spreading path limiter or co-operating force and path measuring device.

Abstract: A form representation of a form is created including an arrangement of form elements with possible data selections from which a form user will make actual selections. A grid representation is automatically created based on the form representation, including an array of cells corresponding to the form elements and the selections and being organized in a first dimension per the arrangement of the form elements and in a second dimension per the possible data selections. Subsequently, (i) properties are identified and property values are assigned to array cells, the property values being user-visible in respective cells in a properties view, and (ii) functions are created for performing calculations using the actual data selections and the property values to yield derived values during use of the form. Events may also be triggered that are defined in the form object.
