Description

包皮环切器 技术领域
本发明涉及医疗器械领域，特别地，涉及一种包皮环切器。
背景技术
阴茎的包皮是过剩的皮肤，位于接近阴茎的远端，也称为阴茎包皮。包皮基本覆盖阴茎的头部，也称为阴茎的龟头、阴茎头或者简称龟头。包皮环切为其中部分或全部的阴茎包皮被去除的外科手术。男性的包皮环切是世界上最常见的手术步骤之一，并且从古代开始已经因为仪式以及卫生的原因而进行。现在，其可能因为临床的原因而执行或者为了遵从宗教或者文化的实践(也称为非治疗的包皮环切)。非治疗的包皮环切通常由一般的从业者和非临床医生在宗教或文化的团体中通常地进行。世界上大约三分之一的男性在其生命的一些时间接受包皮环切。包皮环切通常在出生后立即进行、或者在儿童期间或者青春期之间或者偶尔在年轻人上(即在十几年之后)进行。
目前，割包皮通常采用激光或者机械直接割除的方法，该方法使包皮切口不光滑完整，同时出血量大、手术时间长、术后不易恢复。因此，市场上出现了包皮环切器，但现有的包皮环切器虽然能够一次性切除多余的包皮，但由于其尺寸固定，不能适用于所有尺寸的阴茎，因此，需要根据手术的实际情况而更换不同的规格的环切器。
发明内容
本发明提供了一种包皮环切器，以解决现有的包皮环切器的兼容性有限的技术问题。
本发明采用的技术方案如下：
一种包皮环切器，包括用于定位的固定支座，固定支座上沿同一轴线加工有第一通孔及第二通孔，刀架轴贯通第一通孔，刀架轴位于固定支座外部的第一端连接有用于将刀架轴锁紧定位至固定支座上的锁紧机构，刀架轴的第二端连接用于包覆阴茎龟头的保护罩，保护罩经第二通孔延伸至固定支座之外，保护罩与刀架轴同轴且可拆卸式连接；
第二通孔处设有与保护罩间隙配合的定位套且定位套与固定支座可拆卸式连接，定位套与保护罩之间的间隙与包皮的厚度适应，以供包皮延伸进入固定支座内。
进一步地，可拆卸式连接为螺纹连接、花键连接或者卡接。
进一步地，锁紧机构为调节锁紧螺母。
进一步地，保护罩包括用于与刀架轴同轴连接的连接段及与用于容纳阴茎龟头的容纳腔，连接段与容纳腔之间经倾斜段过渡连接，倾斜段沿容纳腔至连接段的方向口径渐缩。
进一步地，定位套呈圆环状，定位套朝向固定支座外的端部设有外径增大的凸环，凸环与固定支座的底面抵靠，定位套朝向固定支座内的端部设有内径逐渐增大的尖锐部，尖锐部与倾斜段配合，用于对待切割的包皮进行限位。
进一步地，刀架轴上设有绕刀架轴转动连接的旋转刀架，旋转刀架上设有用于切割包皮的切刀，切刀经锁紧件固定至旋转刀架上。
进一步地，切刀的刀尖位于倾斜段与尖锐部的相接处。
进一步地，旋转刀架与固定支座之间设有用于施加预紧力至旋转刀架上的弹性件。
进一步地，旋转刀架连接有驱动其自动转动以进行包皮自动切割的驱动机构。
进一步地，驱动机构包括设于固定支座上的电机，电机经传动轴输出动力，传动轴伸入固定支座内，且传动轴在固定支座内与旋转刀架联动连接。
本发明具有以下有益效果：
本发明包皮环切器，通过在刀架轴上设置与其同轴且可拆卸式连接的保护罩，在固定支座的第二通孔处设置与其可拆卸式连接的定位套，通过更换不同尺寸的保护罩和定位套，使得本发明包皮环切器能够适用于不同大小尺寸的阴茎，进而可以经同一包皮环切器对不同尺寸的阴茎进行包皮环切手术，适用面广，且操作简便，省时省力。
除了上面所描述的目的、特征和优点之外，本发明还有其它的目的、特征和优点。下面将参照图，对本发明作进一步详细的说明。

具体实施方式
以下结合附图对本发明的实施例进行详细说明，但是本发明可以由权利要求限定和覆盖的多种不同方式实施。
实施例一：
本发明的优选实施例提供了一种包皮环切器，本实施例包皮环切器可以对不同尺寸的阴茎进行包皮环切手术，适用范围广，具有很大的实用性。具体地，参照图1，本实施例包皮环切器包括用于定位的固定支座10，固定支座10上沿同一轴线加工有第一通孔11及第二通孔12，刀架轴20贯通第一通孔11，刀架轴20位于固定支座10外部的第一端连接有用于将刀架轴20锁紧定位至固定支座10上的锁紧机构30，刀架轴20的第二端连接用于包覆阴茎龟头的保护罩40，保护罩40经第二通孔12延伸至固定支座10之外，保护罩40与刀架轴20同轴且可拆卸式连接；第二通孔12处设有与保护罩40间隙配合的定位套50且定位套50与固定支座10可拆卸式连接，定位套50与保护罩40之间的间隙与包皮的厚度适应，以供包皮延伸进入固定支座10内。
工作时，选择匹配的保护罩40及定位套50，将保护罩40安装至刀架轴20上，定位套50安装至第二通孔12处，通过调整刀架轴20沿其轴向的距离，使得保护罩40将待手术的阴茎的龟头包覆住，且阴茎的包皮则经保护罩40与定位套50之间的间隙延伸至固定支座10内并定位，从而为后续的包皮环切做好准备。
本实施例包皮环切器，通过在刀架轴20上设置与其同轴且可拆卸式连接的保护罩40，在固定支座10的第二通孔12处设置与其可拆卸式连接的定位套50，通过更换不同尺寸的保护罩40和定位套50，使得本发明包皮环切器能够适用于不同大小尺寸的阴茎，进而可以经同一包皮环切器对不同尺寸的阴茎进行包皮环切手术，适用面广，且操作简便。且本实施例中，由于保护罩40与刀架轴20同轴设置，且经刀架轴20延伸出固定支座10外的端部来调整保护罩40与阴茎龟头的配合位置，调节方便，通过锁紧机构30将刀架轴20固定至固定支座10上，避免了手术过程中的位置晃动导致的环切误差。进一步地，定位套50与保护罩40之间的合理间隙，进一步提高了包皮切割时的定位准确性，且定位套50对包皮切割处的保护起到了止血的作用。
本实施例中，可拆卸式连接为螺纹连接、花键连接或者卡接。例如，保护罩40与刀架轴20之间、定位套50在固定支座10的第二通孔12处螺纹连接、花键连接或者卡接连接，以便于快速更换相应规格的保护罩40、定位套50，以满足不同大小阴茎(大人、小孩皆可)的包皮环切需求。
本实施例中，锁紧机构30为调节锁紧螺母，当刀架轴20调整至合适位置后，通过调节锁紧螺母将其锁紧固定至固定支座10上，使得保护罩40得到稳固定位。
本实施例中，优选地，保护罩40包括用于与刀架轴20同轴连接的连接段41及与用于容纳阴茎龟头的容纳腔42，连接段41与容纳腔42之间经倾斜段43过渡连接，倾斜段43沿容纳腔42至连接段41的方向口径渐缩。本实施例通过口径沿容纳腔42至连接段41渐缩的倾斜段43，可以更好地对包皮进行定位，以使得包皮的边缘贴附于倾斜段43上，避免了环切时切口的倾斜。
本实施例中，优选地，定位套50呈圆环状，定位套50朝向固定支座10外的端部设有外径增大的凸环51，凸环51与固定支座10的底面抵靠，定位套50朝向固定支座10内的端部设有内径逐渐增大的尖锐部52，尖锐部52与倾斜段43配合，用于对待切割的包皮进行限位。本实施例，通过尖锐部52与倾斜段43的配合，可以对待环切的包皮进行准确的定位，保证切口光滑及不倾斜。
优选地，为了便于进行包皮环切操作，本实施例中，可选地，刀架轴20上设有绕刀架轴20转动连接的旋转刀架60，旋转刀架60上设有用于切割包皮的切刀61，切刀61经锁紧件62固定至旋转刀架60上。优选地，切刀61的刀尖位于倾斜段43与尖锐部52的相接处。采用此种结构的切刀61进行环切时，包皮的前端包覆于倾斜段43处且其外缘经尖锐部52抵触，既能很好地保证环切的定位精度，又能通过尖锐部对包皮切割处压紧，很好地起到术中术后止血的作用。
优选地，旋转刀架60与固定支座10之间设有用于施加预紧力至旋转刀架60上的弹性件70，本实施例中，弹性件70为弹簧，通过设置弹簧对旋转刀架60施加向下的作用力，使得切割操作简便可靠。
实施例二：
图2是本发明优选实施例二包皮环切器的结构示意图，参照图2，实施例二在实施例一的基础上增加了驱动旋转刀架60自动转动以带动切刀61进行包皮自动切割的驱动机构。
本实施例中，驱动机构包括设于固定支座10上的电机80，电机80经传动轴81输出动力，传动轴81伸入固定支座10内，且传动轴81在固定支座10内与旋转刀架60联动连接。具体地，传动轴81在位于固定支座10内的端部连接有驱动齿轮82，驱动齿轮82与旋转刀架60的外周缘齿轮配合，在电机80的动力作用下，传动轴81带动驱动齿轮82，进而带动旋转刀架60绕刀架轴20转动，进而实现了固设于旋转刀架60上的切刀61的环向切割。本实施例借助驱动机构对旋转刀架60的作用，实现了包皮环切手术的自动控制，操作简便。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
