Description

医用内窥广角胶囊镜头
技术领域
本发明涉及医疗镜头结构技术领域,尤其涉及一种医用内窥广角胶囊镜头。
背景技术
现今人类对于自身的安全健康日益关注,医疗卫生行业蓬勃发展,对病灶的检测技术也日益提高。早期使用X光透射,对骨头的伤痕,裂纹等效果好,为了确认消化系统的问题,需要服用“钡餐”,通过X光观察硫酸钡在体内的运动,间接了解消化系统问题。随后发明了医疗内窥镜,通过插管,观察食道和胃内壁的状况,终于可以对消化系统,消化内壁进行直观的直接确认。虽然插管内窥镜解决了直接观察,但只能观察食道和胃,更深层的区域,如肠道(大肠,小肠等)因为位置远,结构曲折复杂而不能观察。
综上可知,现有技术在实际使用上显然存在不便与缺陷,所以有必要加以改进。
发明内容
针对上述的缺陷,本发明的目的在于提供一种医用内窥广角胶囊镜头,其可以实现大视场角度,优秀的景深,使得镜头能从广度和深度成像更好。
为了实现上述目的,本发明提供一种医用内窥广角胶囊镜头,包括一透明外壳,该外壳内设有一底座,所述底座上设有一镜筒,所述镜筒前端设有弧形镜片一,且所述镜筒内部设有镜片二、遮光片一、镜片三、遮光片二、遮光片三及镜片四,所述镜筒末端设有一滤光片。
根据本发明的医用内窥广角胶囊镜头,所述底座的内侧通过卡齿与镜筒的外壁相互配合。
根据本发明的医用内窥广角胶囊镜头,所述滤光片与所述镜筒末端设置一定间隙。
本发明提供了一种医用内窥广角胶囊镜头,其特征在于,包括一透明外壳,该外壳内设有一底座,所述底座上设有一镜筒,所述镜筒前端设有弧形镜片一,且所述镜筒内部依次设有镜片二、遮光片一、镜片三、遮光片二、遮光片三及镜片四,所述镜筒末端设有一滤光片。借此,本发明实现大视场角度,优秀的景深,使得镜头能从广度和深度成像更好。
附图说明
图1是本发明的医用内窥广角胶囊镜头结构示意图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
参见图1,本发明提供了一种医用内窥广角胶囊镜头,包括一透明外壳101,该外壳101内设有一底座10,所述底座上设有一镜筒20,所述镜筒20前端设有弧形镜片一30,且所述镜筒20内部设有镜片二40、遮光片一50、镜片三60、遮光片二70、遮光片三80及镜片四90,所述镜筒20末端设有一滤光片100。
所述底座10的内侧通过卡齿与镜筒20的外壁相互配合。
所述滤光片100与所述镜筒20末端设置一定间隙。
本发明胶囊镜头如同一个胶囊药丸,随着消化系统的管道运动,并记录传输图像资料,用于了解病灶的直接信息。
本发明的内窥镜胶囊系统应用的一个部件。作为胶囊镜头,最需求的功能为角度(视场角)要大,能看到更多的区域和画面,景深要好,即在任意距离都能成像,然后是画面清晰。我司这款胶囊镜头,视场角大于162°,景深极佳,从外衣表面到无穷远均能成像,即外衣碰到的消化道表面亦能拍摄成像。
综上所述,本发明提供了一种医用内窥广角胶囊镜头,其特征在于,包括一透明外壳,该外壳内设有一底座,所述底座上设有一镜筒,所述镜筒前端设有弧形镜片一,且所述镜筒内部依次设有镜片二、遮光片一、镜片三、遮光片二、遮光片三及镜片四,所述镜筒末端设有一滤光片。借此,本发明实现大视场角度,优秀的景深,使得镜头能从广度和深度成像更好。
当然,本发明还可有其它多种实施例,在不背离本发明精神及其实质的情况下,熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形,但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
