Abstract: A medical instrument set having a guide tube and a medical instrument which can be introduced into the guide tube for processing and removing tissue in an intervertebral disc space between two adjacent vertebral bodies. The instrument has a shaft which is rotatable about its extension direction. A set of bristles comprising at least two bristles, with at least one space therebetween, is provided in a distal end region. The space is such that, during rotation of the shaft about its extension direction, processed tissue is movable in an axial direction inside the space. The invention further relates to a medical device and to a medical method.

This aim is achieved by an instrument set for spinal operations, including a guide rod, which has a cavity extending along the axis of the guide rod, and a guide tube, which can be received in the cavity of the guide rod, wherein the guide rod has a distal lip, which is arranged eccentrically to the cavity and/or to a center axis of the guide rod.

Abstract: In an intervertebral implant having at least two upper and two lower contact bodies that have contact surfaces. An actuator has a threaded body which has an extension axis and is provided with opposite-handed threads arranged one behind the other. Wedges sit on the threaded body in an axially moveable manner and can be moved along the threaded body by rotating the same. Ramps of at least one ramp body of a wedge engage at least with counter-surfaces of at least some of the contact bodies and extend toward one another at a finite angle of less than 90°. The wedges are double wedges having two ramp bodies arranged one behind the other, and the ramps of one ramp body are oriented differently to the ramps of the other ramp body. The ramps of the first ramp body engage directly with the contact bodies laterally.

Abstract: An intervertebral implant with a support portion (1.1) and a proximal contact portion (1.3) adjoined thereto in the longitudinal direction, is better adapted, as an intervertebral implant, to the contours of the lower and upper sides of the vertebrae that are spaced apart by the implant. An upper side (1.6) and a lower side (1.7) of the implant are configured symmetrically relative to a horizontal center plane (L-Q). In particular a height of the support portion between the transition (U) thereof to the contact portion (1.3) and a distal end face (1.2) facing away from the contact portion (1.3) are greater than the height at the transition (U) and at the distal end face (1.2).

Abstract: A medical device includes a guide unit having a guide tube with a longitudinal axis, a proximal first coupling part fixedly connected to the guide tube, and a distal pivoting head with a cylindrical surface. An actuating tube is axially movable in the guide tube and is connected to the pivoting head. The actuating tube causes a pivoting movement of the pivoting head via a proximal operating element. In the device, in order to orient a distal guide element for a rotatable surgical tool more precisely and thus angularly orient the working head of such a tool, the operating element is pivotable about the longitudinal axis and causes the pivoting movement of the pivoting head by the axial displacement of the actuating tube.

Abstract: A device (1) for fixating a rod (10) on a bone with a tulip, with a pedicle screw (2) and with a tightening screw (5). The rod clamp (6) is pivotable to the tightening screw and can follow transverse motions of the rod (10). This increases the stability of the entire structure, particularly in the application in spine surgery.

Abstract: To reduce the stress of a patient as much as possible during a percutaneous spine surgery for inserting an interbody cage between two vertebrae, between which the intervertebral disk was damaged and was therefore removed, a guide sleeve is provided for the spine surgery, which is characterized by a non-cylindrical jacket. A kit is further provided for spine surgery with at least one guide sleeve of the above-mentioned type and a dilator, having an outer contour that is adapted to the contour of the lumen of the guide sleeve. A kit for spine surgery is further provided including a guide sleeve and an interbody cage, which is to be inserted through this guide sleeve. The lumen of the guide sleeve is adapted to a maximum cross-sectional contour of the interbody cage.

Abstract: For inserting a cage in the intervertebral disk space between two vertebrae, an instrument set includes a guide wire with a plurality of dilators that can be pushed over the guide wire and one over another, with a working sleeve and with a cage, in which the working sleeve is designed in its distal area such that it makes possible the fixation of its distal area in the direction of its extension with angular mobility or variable angular orientability of its proximal end.

Abstract: An interbody cage, which has lattice-like or grid-like areas for better connection/fusion into the area of the vertebra. The cage has especially an outer frame, which includes massive support parts and, and an inner grid body. The frame determining the outer contour and the lattice or grid areas located within same are made in one piece. The cage is prepared by sintering, such as by electron beam melting or laser sintering.

Abstract: When processing bone tissue, the work site is often out of alignment with the insertion path of a tool device. A tool device (1) is provided with an endoscope (2), through the working channel (2.1) of which a guiding part (3) and a tool part (5) guided in this can be moved with their distal ends to a distal working area. The tool part (5) has a tool shaft (5.1) with a rotating tool (5.3). In the tool device there is a secure connection between the endoscope and the guiding part, during the task, and, this connection can be established in a simple manner prior to the beginning of the task and it can also be released again in a simple manner after the task ends. The guiding part (3) is able to be connected rigidly with the endoscope (2) axially.

Abstract: A cutter for spine surgery is provided, especially for use in the area of the delicate cervical spine. The cutter includes a cylindrical cutter shank with cutter teeth formed at the distal end thereof. The cutter teeth at the distal end of the cutter shank are formed by grooves in the wall of the cutter shank. The grooves become deeper and expand from the outer radius of the cutter shank towards the distal end such that teeth narrowing towards the distal end with increasing height are formed between them. This guarantees especially gentle cutting in the area of the cervical spine, without surrounding delicate tissue being additionally jeopardized.
