The present invention relates to a method for designing an implant comprising designing a contour curvature of the implant so that an articulating surface of the implant is designed to correspond to a simulated healthy articulating surface of a damaged articulating surface of a joint. The implant is provided with at least one positioning mark designed to be used for determining the orientation in which the implant is to be placed in a recess made in a damaged articulating surface of a joint. Further, the present invention relates to methods for positioning and inserting a medical implant in a recess.

Method of designing and positioning a medical implant and an implant comprising a positioning mark

A method for designing an implant includes designing a contour curvature of the implant so that an articulate surface of the implant is designed to correspond to a simulated healthy cartilage surface reconstructed from a 3D model based on one or more images taken with MRI or CT-scanning of a damaged cartilage surface of a joint; and providing a positioning mark on a surface of the implant. The positioning mark is provided such that the positioning mark is parted from the center of the implant to be visible for a surgeon and is adapted to be used for indicating a rotational position of the implant to the surgeon.

System of designing a guide tool and/or surgical kit tools and/or an implant comprising a positioning mark

A system for determining and visualizing damage to an anatomical joint of a patient. The system is to: obtain a three dimensional image representation of an anatomical joint which is based on a medical image stack; determine damage to an anatomical structure in the anatomical joint by analyzing the medical image stack; mark damage to the anatomical structures in the obtained three dimensional image representation; obtain a 3D model based on the three dimensional image representation; and create a graphical user interface (GUI). The GUI may comprise: functionality to visualize and enable manipulation of the at least one 3D model; functionality to enable removal of the visualization of the anatomical structure from the 3D model; functionality to visualize and enable browsing of the medical image stack; and functionality to visualize the position of the medical image that is currently visualized.

Determination and visualization of damage to an anatomical joint

In accordance with one or more embodiments herein, a system for creating a decision support material indicating damage to at least a part of an anatomical joint of a patient, wherein the created decision support material comprises one or more damage images, is provided. The system comprises a storage media and at least one processor, wherein the at least one processor is configured to i) receive a series of radiology images of the at least part of the anatomical joint from the storage media; ii) obtain a three-dimensional image representation of the at least part of the anatomical joint which is based on at least a part of said series of radiology images, by generating said three-dimensional image representation in an image segmentation process based on said series of radiology images, or receiving said three-dimensional image representation from a storage media; iii) identify tissue parts of the anatomical joint in at least one of at least a part of said series of radiology images and/or the three-dimensional image representation using image analysis; iv) determine damage to the identified tissue parts in the anatomical joint by analyzing at least one of at least a part of said series of radiology images and/or the three-dimensional image representation of the at least part of the anatomical joint; v) determine suitable sizes and suitable implanting positions for one or more graft plugs based on the determined damage; vi) mark damage to the anatomical joint and suitable sizes and implanting positions for the one or more graft plugs in the obtained three-dimensional image representation of the anatomical joint; and vii) generate a decision support material, where the determined damage to the at least part of the anatomical joint and the suitable sizes and implanting positions for the one or more graft plugs are marked in at least one of the one or more damage images of the decision support material, and at least one of the one or more damage images is generated based on the obtained three-dimensional image representation of the at least part of the anatomical joint.

Guide tool for cartilage repair

A system for creating decision support material indicating damage to an anatomical joint of a patient. The system is configured to: i) receive a series of radiology images of at least a part of the anatomical joint; ii) obtain a three-dimensional image representation of the at least part of the anatomical joint; iii) identify tissue parts of the anatomical joint using image analysis; iv) determine damage to the anatomical joint by analyzing said image representation; v) mark damage to the anatomical joint in the obtained three-dimensional image representation; and vi) generate decision support material. The analysis comprises: detecting an irregular shape of a contour of a tissue part; and/or detecting that the intensity in an area within or adjacent to bone and/or cartilage parts differs from a predetermined value; and/or comparing at least one identified tissue part with a template representing a predefined damage pattern for an anatomical joint.

The present invention relates to a surgical kit, a saw guide and other related tools used in the osteotomy for temporary removal of a piece of a first bone structure to gain temporary access for treatment of defects of a second bone structure, as well as methods for designing and manufacturing said tools.

Embodiments of the present disclosure relate to design methods for designing a mandrel for hammering, pressing and/or pushing an implant into position in a recess made in a joint and firmly attach the implant to the bone of a patient, the mandrel comprising a contacting surface adapted to be in contact with an articulate surface of the implant to be inserted, the method comprising designing the contacting surface of the mandrel to fit the articulate surface of the implant in that the contacting surface of the mandrel has a cross-sectional profile corresponding to the cross-sectional profile of the implant.

Implant for cartilage repair

A drill tool for implant surgery including a first drill part having a first, smaller diameter for drilling a recess for an implant post and a second drill part having a second, larger diameter for drilling a recess for an implant hat is disclosed. The second drill part has one or more shape cutting edges and one or more sharp pre-cutting edges extending beyond said one or more shape cutting edges.

Implant specific drill bit in surgical kit for cartilage repair

A method of manufacturing a surgical kit for cartilage repair in an articulating surface of a joint, comprising the steps of receiving radiology image data representing three dimensional image of a joint; generating a first three dimensional representation of a first surface of the joint in a trainable image segmentation process dependent on a trained segmentation process control parameter set and said radiology image data; generating a set of data representing a geometrical object based on said first surface, wherein said geometrical object is confined by said first surface; generating control software adapted to control a CAD or CAM system to manufacture a surgical kit for cartilage repair dependent on said set of data representing a geometrical object and on a predetermined model of components of said surgical kit.

Method and node for manufacturing a surgical kit for cartilage repair

A system for performing osteochondral transplantation surgery includes a harvesting guide tool for harvesting one or more osteochondral plugs and a transfer guide tool for insertion of each osteochondral plug in a damage site on an articular surface of a joint. A cartilage contact surface of each respective guide tool is adapted to follow the shape of a surface of cartilage or subchondral bone such that they conform to each other. Each respective guide tool includes one or more guide channels adapted to receive a respective surgical tool that slides within the guide channel, and is supported by the guide channel during surgery. The guide channels are configured to harvest and insert a plurality of osteochondral plugs of different sizes. The interiors of the guide channels are provided with markings for marking a rotational position of harvested plugs enabling positioning of the osteochondral plugs at a predetermined angle of rotation.
