The handheld surgical tool comprises a handle (1), an instrument shaft (2) and a navigation device (3). The navigation device (3) comprises at least one sensor unit (31) for sensing positional data, a computing unit (33) configured to determine a position in space based on signals of the sensor unit (31), at least one set key (35) and a position memory (36) configured to store a data set for a position upon activation of the at least one set key (35). A comparator (4) is operatively connected to the position memory (36) and configured for comparing an actual position against a position stored in the position memory (36) in at least two different operation modes and for generation of a deviation signal, wherein a first operation mode differs from the second operation mode in that it is configured for a reduced comparison only which lacks at least one spatial dimension opposed to the second operation mode. A feedback device (5) is provided supplied with the deviation signal and being configured to indicate direction and preferably magnitude of any deviation.

An intervertebral fusion implant for the fusion of two adjacent vertebrae (9, 9) comprises an elongate, adjustable support body (2), of which the lower and upper cover surfaces (24, 25) are designed to bear on end-plates (92, 93) of the adjacent vertebrae (9, 9), wherein a side bracket (3) is provided, which is pivotable laterally about a hinge (30), and of which the bottom face and top face are designed to bear on the end-plates (92, 93). The support body (2) furthermore is provided, on the cover surface (24) thereof, with a lifting plate (40) which, by means of a lifting mechanism (4), 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 (92). Thereby, both adaptions of width as well as of height are achieved. Optimal adjustability and consequently adaptability to the individual anatomical conditions in the intervertebral space (91) is achieved, while maintaining a compact form factor for ease of implantation in minimally invasive surgery.


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. Thus it can be implanted more reliably, wherein the risk of overloading or injury to the vertebrae and the nerves and ligaments of the vertebrae is decreased.

The consortium is composed of 4 SMEs, 3 industrial, 3 research institutes. The project will last 3 years and will deliver a complete sensor system.


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.

The invention relates to an intervertebral fusion implant for fusing two adjacent vertebrae, comprising an adjustable support body, the base surface and cover surface of which are configured to bear on end plates of the adjacent vertebrae, wherein provision is made for a side bracket, which can be pivoted laterally about a hinge and the base and cover of which have a planar design, and provision is made for an actuator for pivoting out the side bracket into a position (working position) spread from the support body. As a result, the implant has particularly small dimensions and can, after assembly at the envisaged implantation site, be actuated in such a way that it becomes larger and thereby affords a larger support surface for support in the intervertebral space. Thus, even comparatively large-area defects can be treated by minimally invasive surgery.

An intervertebral fusion implant for fusion of two adjacent vertebrae, comprising a base piece and a cover piece, which are each designed to bear on a facing end plate of one of the adjacent vertebrae, wherein the cover piece is adjustable in height with respect to the base piece, wherein a ratchet mechanism, provided between base piece and cover piece, effects a stepped adjustment of height and secures an adopted height against reversal. In this way, a defined expansion can be achieved that is dependent on the number of actuations. A precise control of the state of expansion is permitted, specifically in a purely haptic manner. Moreover, a locking of the adopted state of expansion is achieved with the ratchet mechanism.

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.


The invention relates to an intervertebral fusion implant for fusing two adjacent vertebrae, comprising a base piece and a cover piece and also a spreading means, wherein the base piece and the cover piece are connected by a rocker which is situated therebetween and externally coupled, and the spreading means is a spreader clip on the rocker and a drive device is provided for the spreader clip. The spreader clip is used to erect the rocker such that the implant expands in terms of height. As a result of the external coupling of the rocker, a large lifting travel is available. Furthermore, the spreader clip has a blocking effect in relation to an unwanted return as a result of the frictional forces thereof.
