Title
(EN) NONMETAL IMPLANT SCREW LOCKING STRUCTURE
(FR) STRUCTURE DE VERROUILLAGE DE VIS D'IMPLANT NON MÉTALLIQUE
(ZH) 非金属植入物螺钉锁定结构
Abstract
(EN)
A nonmetal implant screw locking structure, comprising a nonmetal implant (1) and a metal screw (2). A fixing hole (11) is provided on the nonmetal implant (1). The front portion of the metal screw (2) is a bone-connecting thread (21), and, the tail portion is provided with a sharp thread (22) or a spike (23). The locking structure has the advantage of being easy to manufacture and process. The locking structure is applicable in nonmetal implants such as a trauma bone plate and a spinal fusion cage.
(FR)
La présente invention concerne une structure de verrouillage de vis d'implant non métallique, comprenant un implant non métallique (1) et une vis métallique (2). Un trou de fixation (11) est disposé sur l'implant non métallique (1). La partie avant de la vis métallique (2) est un filetage de liaison à l'os (21), et la partie de queue est pourvue d'un filetage pointu (22) ou d'une pointe (23). La structure de verrouillage présente l'avantage d'être facile à fabriquer et à traiter. La structure de verrouillage est applicable dans des implants non métalliques tels qu'une plaque osseuse de traumatisme et une cage de fusion vertébrale.
(ZH)
一种非金属植入物螺钉锁定结构,包括非金属植入物(1)及金属螺钉(2)。该非金属植入物(1)上设有固定孔(11)。该金属螺钉(2)前部为接骨螺纹(21),尾部设有尖螺纹(22)或尖刺(23)。该锁定结构具有生产加工简单的优点。该锁定结构可应用到创伤接骨板、脊柱融合器等非金属植入物上。
