【3750】技术工具(1 / 1)

“是什么样的问题不行?”只听张大佬的口气很叫人担心,方理事细问起几位心外科医生。

说来她或许看过此类手术但是非心外科专家,没有在手术里头亲手做过此类操作,所以肯定没有外科医生那种这方面的经验感觉。现场有医生说行有大佬质疑不行,究竟是不是行,可能需要心外科同行再进一步做解释说明了。

在此情形下,谢婉莹不意外收到张大佬和任师兄两位顶尖心外科专家意味深长的一瞥:你说行,你给病人朋友解释吧。反正我们觉得是不行。

足以说明这个难点是众所周知而且心外科资深专家都认为是没法解决的。她谢婉莹不可能回避这样的现实技术问题,因为在客观上确实存在。

“方老师,如张主任说的,人体的有些地方让医生去做手工缝合是很非常难缝好的,这是人体组织某些部位的特殊解剖结构所决定的。”谢婉莹道,“张主任想说的是,正因为这个原因胸腔镜难以做到全胸腔镜下四支病变的手术。”

“用手术机器人做是不是好些?我听说它对手术视野的放大倍数比胸腔镜能大许多。”方理事再问,显然是要极力为病人争取最后的希望。

“这个问题,不是说能不能看不看清楚手术视野单方面的问题。”谢婉莹道。

确切地说是手感。医生的手拿长距离工具去做缝合的操作比拿短工具缝难多,如前面讲过的,长距离工具传导感觉的信息慢或是缺失会导致医生操作的手感严重缺乏。更何况,这地方在有充分手感下医生都难以缝好,更别说是缺失医生手感下来做缝合。..

“要怎么解决这个问题?”方理事听完是跟着犯难了,不明白的是她刚说的是可以考虑的话,按现在这个说法岂不是毫无希望的事儿。

“方老师您知道的,您看过很多外科手术,清楚医学技术的进展是多方面综合的结果,仅靠一个技术发展是难以达到总体手术目标。内镜手术除要能把医生的手术视野扩大,必须同时解决医生其它操作的技术难点不然是一无是处。”

“我明白了。”不愧是大佬,方理事一点即通,“你说的是吻合器。”

医生手工难以缝好的地方用吻合器来协助。不要说内镜手术里头,传统手术里头用吻合器来解决这类难点的手术案例一样有许多。

腔镜手术的话由于手感缺失问题,用吻合器来协助是比传统手术更多些,可以说部分地方必然是更需要吻合器来解决难题。如现在在讨论的胸腔镜治疗单支病变手术,之所以能手术成功率大大提升也是因用了吻合器。B公司演示的TECAB同用了吻合器。

这里再说到另一问题。吻合器型号各式各样,不是通用的。单支病变所用的血管吻合器肯定专门为这类腔镜手术开发的,专门用来衔接乳内动脉和左前降支的特殊型号。言外之意想做四支病变的手术如需要血管吻合器协助尚未发明出来。
