Description

一种用于内窥镜冲洗吸引的手术系统和操控方法 【技术领域】
本发明涉及医疗器械技术,尤其涉及一种用于内窥镜冲洗吸引的手术系统和操控方法。
【背景技术】
目前,泌尿系结石在我国发病率较高,全国约1%~5%,南方高达5%-10%,每年需要进行大量的泌尿系结石手术。根据泌尿系结石的不同位置,主要有肾结石、输尿管结石、膀胱结石。在输尿管结石和肾结石手术中,肾结石现阶段主要采用经皮肾镜手术,对于直径小于2cm的结石,输尿管软镜配合钬激光取石手术,近年来被泌尿医生广泛采用,因其相比经皮肾镜手术经人体自然通道,出血少,恢复快;相比以往的输尿管切开取石和输尿管硬镜配合钬激光取石,输尿管结石采用输尿管软镜配合钬激光手术取石为最安全和有效的方法。
在以往的输尿管软镜手术时,为了使输尿管软镜顺利进入,临床医学上输尿管软镜碎石操作需导引鞘建立手术通路,以辅助内窥镜与其它器械进入泌尿腔道,并提供连续性操作通道,可在器械反复交换时保护输尿管,减少造成创伤的可能性,同时保护精密器械及软镜免受损坏。而且,在使用输尿管扩张鞘法时,需要先行进入输尿管硬镜,以进行尿道膀胱内窥镜检,以排除尿道狭窄或膀胱内病变,观察输尿管开口情况,扩张输尿管镜,然后进导丝,退出输尿管硬镜,再进入输尿管软镜。这样,需要反复操作几个来回,增加手术时间和操作复杂程度。
同时,为了冲开输尿管口和扩张输尿管,使硬镜顺利进入,输尿硬镜进入的同时需要加生理盐水灌注;在手术过程中,会产生少量出血、絮状物、结石碎片,若灌注水流不能及时将这些带走,会使水中出现“雾霾”现象,视野模糊,影响手术安全和手术进程;这样,就需要手术中加压灌注生理盐水保持输尿管镜视野清晰,手术操作过程大量冲洗水进入肾盂,因为输尿管软镜扩张外鞘操作空间小,手术过程中若灌注压力过高,容易使生理盐水逆流进入血液,引起水中毒。很多结石患者本身存在炎症情况,操作导致的血凝块无法顺利排出体外,导致肾盂内压急剧增高,导致细菌、毒素短时间内大量进入循环系统,生理盐水逆流进入血液会带入细菌、 脓毒液等,产生大量炎性因子,引发菌血症或毒血症,引起全身炎症反应,重者发展至感染性休克,危及生命。
而且,还容易造成在进镜过程中,若灌注压力过大,会使结石冲回肾内,增加手术复杂度。另外,钬激光在使用过程中,会产生大量的热量,若灌注流量不够,容易产生热集聚,从而造成热损伤。
因此,如何使输尿管软镜碎石术中降低输尿管、肾盂内压,有效地预防输尿管软镜碎石术引起脓毒血症及保持手术视野清晰,是目前泌尿外科学关注的难题。
以及在刨削手术中,前列腺增生肥大患者,若使用电切后经尿道取出,因尿道空间有限,需要切得很小块再取出,这样耗费大量的时间,通常需要3个小时左右。现在通常使用刨削方法,大块切除后推回膀胱中,再使用生理盐水充盈膀胱,使用刨削器在膀胱内粉碎,粉碎后的组织通过出水通道和生理盐水一起排出。由于膀胱内压力需要控制在安全范围内,例如11~29.4mmHg(15~40cm水柱)范围,压力太小膀胱未完全充盈,刨削器工作过程中容易损伤膀胱内壁;压力太大容易损伤膀胱并且液体逆流入尿道和肾,造成感染等不良后果。

A.在进镜和取石过程中自动调整灌注流量和吸引压力,使输尿管扩张鞘顶端压力在合理范围,不使结石冲回肾内,不使生理盐水逆流进入血液;
B.在取石过程中保证足够的灌注流量,带走血液、絮状物、结石碎片,使视野清晰,足够的灌注流量及时带走钬激光产生的热量;
C.在取石过程中,若温度超过警戒值,通过脚踏断开主机输出。
同时,在系统灌注模式下采用刨削手术时,针对减少压力太小膀胱未完全充盈、而造成刨削器工作过程中容易损伤膀胱内壁的情况,减少压力太大容易损伤膀胱并且液体逆流入尿道和肾,造成感染等不良后果的情况,通过吸引管道上设置有一次性使用、用于实时监测导引鞘连通的压力值、并调整所述内窥镜冲洗吸引器上负压泵的吸引流量、且使负压吸引压力值保持在用户预先设置附近的压力传感器,通过一次性使用压力传感器监测膀胱内压力,通过调整灌注流量和吸引压力,使膀胱内压力保持在合理的范围,有效避免压力过大或压力过小造成的问题。
另外,该内窥镜冲洗吸引的手术系统,采用通用化的设计方式,在灌注模式下进行输尿管结石和肾结石手术时,由于使用输尿管扩张鞘法时需要先行进入输尿管硬镜,以进行尿道膀胱内窥镜检,以排除尿道狭窄或膀胱内病变和观察输尿管开口情况,以及扩张输尿管镜,然后进导丝、退出输尿管硬镜,再进入输尿管软镜等反复操作几个来回,由于该发明中关键设备及关键部件可以整体切换使用,相比现有手术设备由于通用的问题而增加手术时间和操作复杂程度,该发明可以有效节省手术前期准备、中间切换时间以及降低手术操作难度,可以有效减轻手术患者手术时间、以及手术医师的手术劳动量及时间,提高手术的安全性和可靠性,相对现有技术及设备,可以大大节省整体手术时间,提高手术的效率。
