Description

顺应人体解剖特点的微创胸腔引流管及引流手术器械 技术领域
本发明属于医疗器械领域， 具体涉及一种顺应人体解剖特点的微创胸腔引流管及引流手 术器械。 背景技术
现有的胸腔手术过程中， 其手术部位大多位于侧上胸腔或侧下胸腔部位， 容易损伤肝脾 等组织脏器。 在胸腔手术的引流中采用直管引流， 对于现有的胸腔手术而言， 手术创口大， 术后病人疼痛较剧烈， 无法有效的实现手术微创， 并影响患者的术后恢复。 直管的引流管在 弯折过程中， 会使管体的内径发生改变， 甚至出现管腔的狭窄， 进而影响到引流效果。 发明内容
基于此， 本发明在于克服现有技术的缺陷， 提供一种顺应人体解剖特点的微创胸腔引流 管及引流手术器械， 本发明可以实现胸腔手术的微创， 并使引流管更顺应人体解剖特点， 可 以有效的避免管腔狭窄， 引流效果好。
其技术方案如下：
一种顺应人体解剖特点的微创胸腔引流管， 包括管体， 其管体依次具有外段、 第一弯折 部、 过渡段、 第二弯折部及内段， 外段与过渡段之间通过第一弯折部弯折， 过渡段与内段之 间通过第二弯折部弯折， 内段上至少部分具有与胸腔内壁相贴合的贴合弧段。
在所述管体的内段靠近第二弯折部一侧设有球囊， 在所述管体的外段处设有充气活塞， 充气导管的一端通过导管开口与球囊相通， 另一端与与充气活塞相通。
所述管体的截面呈圆形或椭圆形。
所述内段的端部向内卷曲而形成卷曲端。
所述卷曲端所在平面为第一平面， 所述过渡段、 贴合弧段所在平面为第二平面， 第一平 面相对于第二平面相交叉。
所述外段的端部具有后端管口， 所述内段的前端部具有前端管口， 在内段上还设有侧孔。 在所述外段上设有开关装置或固定装置。 所述管体的外段相对于所述过渡段向下弯折， 所述管体的内段相对于所述过渡段向上弯 折。
所述管体的外段相对于所述过渡段向下弯折， 所述管体的内段也相对于所述过渡段向下 弯折。
所述管体的外段相对于所述过渡段向前侧弯折， 所述管体的内段相对于所述过渡段向上 或向下弯折。
一种顺应人体解剖特点的微创胸腔引流手术器械， 包括：
引流管， 该引流管包括管体， 其管体依次具有外段、 第一弯折部、 过渡段、 第二弯折部 及内段， 外段与过渡段之间通过第一弯折部弯折， 过渡段与内段之间通过第二弯折部弯折， 内段上至少部分具有与胸腔内壁相贴合的贴合弧段；
导丝；
穿剌针， 其包括针体和针头， 该针体内有纵向通道， 在该针体的前端侧壁上设有与其纵 形通道相通的穿剌针侧孔， 该针头前端封闭且为钝头；
皮肤切开刀， 其包括刀柄和刀体， 该刀体包括前端的刃部和后端的根部， 该根部固定在 该刀柄的前端面上， 且该根部的表面与该刀柄的前端面之间形成限位台阶部。
还包括有导引柱， 具有内孔， 其内孔的孔径与所述导丝的孔径相吻合， 其外径小于所述 管体的内径； 导引柱的材质软于所述导丝的材质。
下面对前述技术方案的优点或原理进行说明：
1、在进行胸腔手术时， 将管体的内段通过微创口从胸腔的侧部置入胸腔内部， 其贴合弧 段与胸腔内壁相贴合， 减少对内脏的损伤， 过渡段与内段之间通过第二弯折部弯折， 外段与 过渡段之间通过第一弯折部弯折， 外段弯折后外露并与胸腔外贴合， 以方便将外段固定； 该 引流管可以与人体的胸腔的内壁完美贴合， 减少对人体脏器的损伤， 并可以实现充分有效的 引流。
2、在所述管体的内段靠近第二弯折部一侧设有球囊， 球囊充气之后膨胀， 可以将管体的 内段紧密固定在胸腔的内壁。

4、 所述卷曲端所在平面为第一平面， 所述过渡段、 贴合弧段所在平面为第二平面， 第一 平面相对于第二平面相交叉， 以更好的与人体胸腔的内壁轮廓相吻合。
5、在内段上还设有侧孔以加强引流效果， 如果侧孔为至少两个， 则至少两个侧孔沿所述 管体周向错开。 沿管体周向设置侧孔后， 可以从不同的方向、 不同部位进行引流， 引流效果 更好。
6、 在手术时， 可以通过该导丝的引导作用， 方便的将引流管置入人体胸腔。
7、 如果导丝与管体之间的空隙过大， 可以在所述管体与所述导丝之间还设有导引柱， 以 减少导丝与管体之间的晃动， 提高导丝的导引效果， 导引柱可以采用韧制材料制成。
8、 在所述外段上设有开关装置， 开关装置可以为卡子或夹子， 还可设有固定装置， 用于 将管体的外段与人体进行固定。
9、 该引流管主要有设计方式：
a、所述管体的外段相对于所述过渡段向下弯折， 所述管体的内段相对于所述过渡段向上 弯折， 此时， 该引流管可作为气体引流管；
b、所述管体的外段相对于所述过渡段向下弯折， 所述管体的内段也相对于所述过渡段向 下弯折， 此时， 该引流管可作为液体引流管；
c、所述管体的外段相对于所述过渡段向前侧弯折， 所述管体的内段相对于所述过渡段向 上或向下弯折。 此时， 该引流管可作为卧位引流管， 患者处于卧位， 当内段相对于过渡段向 上弯折时， 为卧位气体引流； 当内段相对于过渡段向下弯折时， 为卧位液体引流。 附图说明
