Description

***手术内窥镜 技术领域
本发明涉及一种微创手术医疗器材， 具体涉及一种***手术用内窥镜。
背景技术
近七十年来对***疾病、***增生疾病国内外均采用经尿道利用电切 环切除的微创技术。称经尿道电切镜。该镜是在窥视下利用环状电切刀， 一条一 条切除组织， 并有电凝作用。 视野的观察靠大量的灌注 5%甘露醇或 5%葡.萄糖来 实现。 近二十年来国内外 95%以上医院， 将这一方法作为治疗***增生的 "金 标准"， 基本放弃了开放性手术治疗***增生的方法。
但这一 "金标 ¾"， 比如现在的电切镜手术存在以下几个缺点： 1.需要大量 使用昂贵的灌洗液， 一个***电切手术约需 3-4万毫升； 2.术中出血， 易与灌 洗液相溶致视野不清， 需频繁放水、 灌水， 不仅浪费大量水质源， 而且术中大量 灌注液体使膀胱内压力持续升高， 易水中毒危及生命； 3液体灌注不能控制膀胱 内压力， 频繁使膀胱高压、 低压， 对全身血液动力学有不良影响； 4.术中用过的 水往往含有病毒、病菌， 溢到手术室或流入下水道将造成环境污染， 甚至造成医 务人员污染。
而现有***手术往往需要使用电切环， 电切环应用存在以下几个问题- 1 对***增生切除， 用电切环需一条一条切除， 一个血管需多次切开再止血； 2 因电切环需要用挖出的操作动作， ***包膜较薄， 为了防止切穿***包膜， 用电切环很难完整切除增生的腺体； 3 残存的腺体是长期***的根源； 4 有切穿膀胱颈部、切穿***包膜损伤直肠等严重并发症可能。残留***腺体 多者致术后排尿困难。 5电切环切除组织呈条状术后病理不易分辨病变的部位， 切除大量条条组织病理科筛选增加工作量。
对***切除； 1 因肿瘤生长的膀胱不同部位， 如后壁、 前后壁交界处 等电切环很难操作； 2切除肿瘤是一片一片切除， 因肿瘤浸犯深肌层时很难彻底 切除；易切穿膀胱而改幵放性手术； 3存在闭孔神经反射时更不易彻底切除肿瘤。 切除肿瘤在病理上很难确诊肿瘤基底是否切除完整； 4目前电切环不能在膀胱内 缝合等操作， 使手术单一， 不能使用一种器械治疗膀胱内其它疾病。 发明内容
本发明所要解决的技术问题是： 提供手术时患处图像更清晰、 可以***多 种器械， 方便医生完成膀胱内各种疾病治疗操作的一种***手术内窥镜。
为了解决以上技术问题，采用的技术方案是：一种***手术内窥镜，包括: 内窥镜体， 所述内 镜体上安装有光源和观察镜； 其特征在于： 所述内窥镜体与 所述观察镜位置相互垂直， 所述内窥镜体的后部依次连接有闭合器和抗逆流封 帽，所述内窥镜体内部置有放置可更换手术器械的腔体； 所述内窥镜体的前部连 接有可供手术器械通过的治疗通道， 并置有二氧化碳气体进气阀门。
所述内窥镜体腔体内可放置橄榄球状剥离钳和电凝剪。
所述抗逆流封帽内部置有单向抗逆流瓣，所述单向抗逆流瓣可以为单层或双 层结构。 、
所述闭合器上前端置有放置硅胶片的反向 7字形装置， 防止气体逆流， 闭合 器至少有两个以上的孔道， 供手术器械通过进行手术。
所述观察镜与内窥镜体之间通过楔形滑台活动连接，所述观察镜可以沿内窥 镜体轴向前后移动。
所述的***手术内窥镜用于***切除、 ***切除、 膀胱憩室切除、 输尿管-膀胱再吻合。
本发明的有益效果在于： 在手术时可以提供清晰的患处图像， 可通过本发 明内窥镜双手操作，'完成切除， 缝合等高难度操作， 并能治疗多种疾病。 方便了 医生进行手术。
附图说明
图 1是本发明***手术内窥镜结构示意图；
图 2是双层单向抗逆流瓣的结构示意图；
图 3是单层单向抗逆流瓣的结构示意图。
具体实施方式
图 1为本发明手术内窥镜结构示意图， 以下实施例以尿道膀胱内手术为例， 结合附图对本发明作进一步说明。
一种***手术内窥镜， 包括： 内窥镜体 8， 所述内窥镜体 8上安装有光源 接口 1和观察镜 2,其特征在于：所述内窥镜体 8与所述观察镜 2位置相互垂直， 所述内窥镜体 8的后部依次连接有闭合器 4和抗逆流封帽 3， 所述内窥镜体 8前 部置有供手术器械通过的冶疗通道 7和二氧化碳气体进气阀门 6， 所述内窥镜体 8腔体内可放置多个可更换器械。
所述内窥镜体 8腔体内放置可更换器械为橄榄球状剥离钳和电凝剪。
抗逆流封帽 3内部设置有单向抗逆流瓣，所述单向抗逆流瓣可以为单层或双 层结构。 ；'
所述闭合器 4前端设有放置硅胶片的反向 7字装置， 防止气体逆流， 闭合器 4至少有两个以上的孔道， 供手术器械通过进行手术。
所述观察镜 2与内窥镜体 8之间通过楔形滑台活动连接，所述观察镜 2可以 沿内窥镜体 8轴向前后移动。
所述的***手术内窥镜用于***切除、 ***切除、 膀胱憩室切除、 输尿管-膀胱再吻合。 还可以应用于子宫镜、 关节镜， 腹腔镜等各种微创手术。
所述进气阀门 6或二氧化碳气源上连接有气体压力表。
如果本发明连接二氧化碳气源， 则在所述内窥镜体 8后部连接的闭合器 4 上安装防漏气帽 3， 所述防漏气帽 3内部设置有朝向内窥镜体 8—侧的单向抗逆 流瓣。 如果本发明 接液体源， 则所述闭合器 4上安装有防漏水帽 3 ' ， 所述防 漏气帽 3 (防漏水帽 3 ' ) 的内部设置有朝向内窥镜体 8—侧的单向抗逆流瓣， 如图 2、 图 3所示。 所述单向抗逆流瓣可以为单层或双层结构。 所述观察镜 2连 接至显示器， 并将治疗通道 7传来的图像信号传输到显示器显示。
本发明使用二氧化碳气作为灌注介质。 其具有价格低廉的优点。 且术中出 血不与气体相溶， 始终保持视野清晰。 利用气腹机供气可控制灌注压力。
尿道膀胱内手术镜是把观察镜 2放在内窥镜体 8上，所述内窥镜体 8与所述 观察镜 2位置相互垂直。 留出操作空间可以同时放入钳子提起肿瘤； 放入电钩或 电凝剪完整切除肿瘤， 甚至侵犯深肌层的肿瘤。 因灌注二氧化碳气体， 可切幵膀 胱全层（气体进入膀胱周间隙压力可控制，不会大量进入。二氧化碳气体易排出， 不会像液体那样造成严重感染并发症。） 可以在本发明实施例所述膀胱镜内缝合 膀胱壁。现在的电切镜是不能达到的。 对***增生， 可应用本发明， 利用发明 的橄榄球型钳完整拨出***，利用另一发明***切碎器，通过本发明内镜取 出， 达到完整切除效果。 目前的电切镜只能做***增生疾病、 表浅的***， 比较单一。 釆用 本发明的尿道膀胱内手术镜不但在治疗上述两种疾病有明显优势，还可治疗如膀 胱憩室切除、 输尿管-膀胱再吻合等等膀胱内其它疾病的治疗。
本实施例所述的尿道膀胱内手术镜气压可控制， 不需膀胱穿刺造痿。 窥镜 在气体中观察比在水中观察清晰度高。
本发明优选利用现有的气腹机， 灌注二氧化碳气体， 代替目前世界通用液 体作为灌注介质。现有的气腹机可控制进气的流量和压力。尿道膀胱内手术镜把 进出气阀 6、 5设在手柄的前端， 使操作空间加大。 观察镜 2放在镜鞘体上， 留 出较大腔内操作空间， 观察镜 2可前后移动， 在切除***时， 可用镜鞘剥离前 列腺， 这时观察镜 2可后移， 使剥离过程可视。 并可以保护观察镜 2头端光学部 分。 尿道膀胱内手术镜在观察镜 2的下端设计呈方形， 便于把镜体通过固定架， 固定在手术床上。 以便手术一人操作。尿道膀胱内手术镜尾端的闭合器 4设有第 一道抗气体逆流皮瓣。 为不同手术需要， 设计有两种闭合器 4。 闭合器 4上可以' 有两孔或三孔。所述闭合器 4上的孔可供手术器械通过进行手术。尿道膀胱内手 术镜也可做为单孔腹腔镜应用。 应用于普外科。 妇产科等。
在闭合器 4的前端有一防逆流皮片结构， 当手术器械从手术镜后端向前端 深入进行手术时， 皮片打开； 同时当膀胱内的气体向外运动时， 皮片可以阻挡气 体逆流，这层皮片结构用于作为第一层防气体逆流装置。上述的硅胶水封帽设计 是在帽腔内有一抗逆流的皮瓣。顺行可以通过器械。腔内有压力时皮瓣因倒三角 形设计， 起到第二层抗逆流作用。
尿道膀胱内手术镜腔内可以操作下列器械：
勺式钳； 可更换剪头的电凝剪， 持针器、 吸引器、 ***切碎器： 本发明 同时可应用于子宫镜， 关节镜等手术。
以上的具体实施方式用来揭示本发明的最佳实施方法， 以使得本领域的普 通技术人员能够应用本发明的多种实施方式以及多种替代方式来达到本发明的 目的。但本发明并不限于上文讨论的实施方式。应当理解基于本发明启示的任何 显而易见的变换或 #代， 也应当被认为落入本发明的保护范围。
