Abstract

本发明属于医疗器械技术领域,具体涉及一种弧形颅颌面接骨板,该弧形颅颌面接骨板包括第一“8”字部以及第二“8”字部,所述第一“8”字部与第二“8”字部通过一连接部相连接成弧形结构,且所述第一“8”字部以及第二“8”字部对称设置,所述第一“8”字部以及第二“8”字部上分别设有可将接骨螺钉的沉头隐藏的沉头孔。本发明通过在弧形颅颌面接骨板上开设有沉头螺钉孔,使接骨沉头螺钉的沉头隐藏在所述沉头螺钉孔的沉孔内,避免了接骨沉头螺钉的沉头由于露在接骨板外而对颅颌面部位造成磨损的技术问题,减少了患者的生理痛苦,也有利于患者的康复。

Description

一种弧形颅颌面接骨板
技术领域
本发明属于医疗器械技术领域,具体涉及一种弧形颅颌面接骨板。
背景技术
颅颌面骨科手术中,通常需要利用颅颌面接骨板和接骨螺钉对颅颌面骨折部位使用相应的接骨板进行实施固定,传统的颅颌面接骨板具有下列生物学缺陷,即在接骨板植入后,接骨螺钉的沉头外露在接骨板外,这样,接骨螺钉的沉头对颅颌面相应部位会造成磨损,会给患者带来不必要的生理痛苦,且不利于患者相应部位的康复。
发明内容
本发明的目的在于解决上述技术问题而提供一种使用后不会对颅颌面皮部造成磨损的弧形颅颌面接骨板。
为实现上述目的,本发明采用如下技术方案:
2、一种弧形颅颌面接骨板,其特征在于,该弧形颅颌面接骨板包括第一“8”字部以及第二“8”字部,所述第一“8”字部与第二“8”字部通过一连接部相连接成弧形结构,且所述第一“8”字部以及第二“8”字部对称设置,所述第一“8”字部以及第二“8”字部上分别设有可将接骨螺钉的沉头隐藏的沉头孔。
所述沉头孔为圆形。
所述第一“8”字部上开设有第一沉头孔、第二沉头孔,所述第二“8”字部开设有与所述第一沉头孔、第二沉头孔分别对称的第三沉头孔、第四沉头孔。
本发明通过在弧形颅颌面接骨板上开设有沉头螺钉孔,这样可以使得接骨沉头螺钉的沉头隐藏在所述沉头螺钉孔的沉孔内,从而避免了接骨沉头螺钉的沉头由于露在接骨板外而对颅颌面部位造成磨损的技术问题,减少了患者的生理痛苦,也有利于患者的康复。
附图说明
图1所示为本发明实施例提供的一种弧形颅颌面接骨板的结构示意图。
具体实施方式
下面,结合实例对本发明的实质性特点和优势作进一步的说明,但本发明并不局限于所列的实施例。
参见图1所示,该图示出了本发明实施例提供的一种弧形颅颌面接骨板的结构。为了便于说明,仅示出了与本发明实施例有关的部分。
3、请参阅图1,一种弧形颅颌面接骨板,该弧形颅颌面接骨板包括第一“8”字部2以及第二“8”字部3,所述第一“8”字部与第二“8”字部通过一连接部1相连接成弧形结构,且所述第一“8”字部以及第二“8”字部对称设置,所述第一“8”字部以及第二“8”字部上分别设有可将接骨螺钉的沉头隐藏的沉头孔。
进一步的,所述沉头孔为圆形。
进一步的,所述第一“8”字部2上开设有第一沉头孔21、第二沉头孔22,所述第二“8”字部3上开设有与所述第一沉头孔、第二沉头孔分别对称的第三沉头孔31、第四沉头孔32。
本发明通过在弧形颅颌面接骨板上开设有沉头螺钉孔,这样可以使得接骨沉头螺钉的沉头隐藏在所述沉头螺钉孔的沉孔内,从而避免了接骨沉头螺钉的沉头由于露在接骨板外而对颅颌面部位造成磨损的技术问题,减少了患者的生理痛苦,也有利于患者的康复。
以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。
