Embodiment Construction

[0117] figure 1 A mandibular resection template 1 according to the invention is shown. The mandibular resection template 1 has a central part / central assembly 2. The central assembly 2 is ready for transfer to the union segment of the mandible. Said central assembly 2 comprises at its two outer ends two separate tool / cutting / saw blade guides 3, wherein the ends define a longitudinal axis. Positioning aids / positioning fins 4 are arranged between the two separating tool guides / blade guides 3 . The parting tool guide does not need to touch the parting tool, while the corresponding saw blade guide part must contact the parting tool, such as a milling cutter, a saw blade or any other metal parting tool. The positioning aid does not have to be connected or docked to the bone, but can also, for example, only be positioned optically. When the positioning aid acts as a positioning fin, it is preferably in physical contact with the bone. The positioning aid / positioning fin 4 is not ...

Abstract

The invention relates to a mandibular resection template (1) comprising a central component (2) which is prepared for attachment to a segment, for example a symphysis segment of a jawbone, such as a mandible or maxilla. At least two cutting tool guide portions (3) are present at the central component (2), a positioning aid (4) being provided between the two or more cutting tool guide portions (3)in order to obtain a spatially correct orientation of the mandibular resection template (1) with respect to the jawbone.

Description

technical field [0001] The present invention relates to a mandibular resection template comprising a central assembly for attachment to a segment, such as a joint segment of a jawbone, such as the mandible or maxilla, wherein at least two separate tool guide portions are provided on the central assembly . Background technique [0002] Saw templates such as mandibular resection templates are known in the prior art. For example, the invention with the patent number WO 2004 / 039266A1 discloses a cutting saw template that can be used for fibula or mandible. Similar devices can also be found in US Patent Nos. US2012 / 0029646 A1, US 2013 / 0338779 A1 and US 2013 / 0304075 A1. [0003] The human jaw, for example, may happen to be damaged or cancerous in an accident, such that the relevant portion of the mandible must be removed. Afterwards, the bone is replenished. More recently, efforts have been made to insert a bone section cut from the fibula into the site of the cleared defect / m...
