具体实施方式
为使本发明的上述目的、特征和优点能够更为明显易懂,下面结合附图对本发明的具体实施例做详细的说明。
术语“第一”、“第二”等仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”等的特征可以明示或者隐含地包括至少一个该特征。
参见图1,本发明实施例提供一种腹腔镜手术机器人的语音提示控制方法,包括:
获取每个机械臂上多个标定点的实时空间位置;其中,机械臂末端适于安装腔镜或手术器械;
根据全部标定点的实时空间位置得到任意两个机械臂上各个标定点的对应位置之间的距离;
根据任意两个机械臂上各个标定点的对应位置之间的距离得到任意两个机械臂之间的最小距离;
根据任意两个机械臂之间的最小距离而判断是否发出语音播报。
这里,在每个机械臂上的不同位置设置多个标定点,通过获取每个机械臂中所有的标定点的实时空间位置,之后根据全部机械臂上的全部标定点的实时空间位置得到任意两个机械臂之间距离最近的两个标定点的实时空间位置,进而根据这两个机械臂之间距离最近的两个标定点的距离而当做这两个机械臂的最小距离,通过这两个机械臂之间的最小距离判断是否发出语音播放而判断是否提示这两个机械臂即将碰撞,进而保证医生和助手需要集中关注腹腔内器械的末端姿态时,也不用担心机械臂之间发生碰撞的问题,进而提高手术效率和成功率。
这里,如图4所示的具有三条机械臂的腹腔镜手术机器人为例,这三条分别记为第一机械臂①、第二机械臂②和第三机械臂③,比如每个机械臂上均设置有三个标定点,第一机械臂上的三个标定点分别记为第一标定点、第二标定点和第三标定点,第二机械臂上的三个标定点分别记为第四标定点、第五标定点和第六标定点,第三机械臂上的三个标定点分别记为第七标定点、第八标定点和第九标定点。可以理解的是,第一标定点在第一机械臂上的位置与第四标定点在第二机械臂上的位置一样,同时第四标定点在第二机械臂上的位置与第七标定点在第三机械臂上的位置一样;第二标定点在第一机械臂上的位置与第五标定点在第二机械臂上的位置一样,同时第五标定点在第二机械臂上的位置与第八标定点在第三机械臂上的位置一样;第三标定点在第一机械臂上的位置与第六标定点在第二机械臂上的位置一样,同时第六标定点在第二机械臂上的位置与第九标定点在第三机械臂上的位置一样;第一标定点在第一机械臂上的位置到第四标定点在第二机械臂上的位置的距离记为Laa,第一标定点在第一机械臂上的位置到第五标定点在第二机械臂上的位置的距离记为Lab,第一标定点在第一机械臂上的位置到第六标定点在第二机械臂上的位置的距离记为Lac,第二标定点在第一机械臂上的位置到第四标定点在第二机械臂上的位置的距离记为Lba,第二标定点在第一机械臂上的位置到第五标定点在第二机械臂上的位置的距离记为Lbb,第二标定点在第一机械臂上的位置到第六标定点在第二机械臂上的位置的距离记为Lbc,第三标定点在第一机械臂上的位置到第四标定点在第二机械臂上的位置的距离记为Lca,第三标定点在第一机械臂上的位置到第五标定点在第二机械臂上的位置的距离记为Lcb,第三标定点在第一机械臂上的位置到第六标定点在第二机械臂上的位置的距离记为Lcc,则第一机械臂与第二机械臂之前实时最小距离为Laa、Lab、Lac、Lba、Lbb、Lbc、Lca、Lcb和Lcc中的最小值。
可以理解的是,可选地,机械臂中每一个连杆均设有一个标定点,当然,机械臂上标定点的数量越多、越密集,两个机械臂之间测出的最小距离越精确。
参见图1,可选地,根据任意两个机械臂之间的最小距离而判断是否发 出语音播报包括:
若任意两个机械臂中的第一机械臂与第二机械臂之间的最小距离小于或等于第一设定值,则发出语音播报;
若第一机械臂与第二机械臂之间的最小距离大于第一设定值,则不发出语音播报。
这里,例如,第一机械臂与第二机械臂之间的最小距离小于或等于第一设定值5cm,则发出语音播报,语音播报的内容至少包括“请注意第一机械臂与第二机械臂即将发生碰撞”,或者播报相类似的内容。若第一机械臂与第二机械臂之间的最小距离大于第一设定值5cm,则不发出语音播报。
参见图2,可选地,腹腔镜手术机器人的语音提示控制方法还包括:
获取机械臂中各个关节的位置信息;
根据指定关节的位置信息与指定关节的上下极限值而判断是否发出指定关节的语音提示。
这里,通过机械臂中各个关节的位置信息与该指定关节对应的上下极限值比较而判断是否进行语音播报,使得医生和助手即使将全部的注意力集中到末端器械,也不会发生各个关节运动至达到上限值对应的位置处或者下限值对应的位置处,进一步提高手术效率和手术成功率。
参见图5,可选地,关节为角度旋转关节或直线位移关节,例如,指定旋转关节1可以绕旋转轴2转动,指定直线位移关节3可以沿滑轨4直线移动。
可选地,获取机械臂中各个关节的位置信息包括:通过关节处的电机编码数值而获取相应关节的位置信息。
这里,也就是说各个关节的运动是由对应电机驱动的,进而可以通过获取电机编码数值而得到该关节的转动角度值,通过该关节的转动角度值与该关节对上下极限值比较而判断是否发出语音播报。
参见图2,可选地,根据关节的位置信息与相应关节的上下极限值而判断是否发出相应关节的语音提示包括:
若指定关节的位置信息与上下极限值中的下限值的差值的绝对值小于或等于第二设定值,则发出语音播报;
若指定关节的位置信息与上下极限值中的下极限值的差值的绝对值大于第二设定值,则不发出语音播报。
这里,例如,指定关节是属于第一机械臂中的,指定关节是角度旋转关节,指定关节的角度范围为-40°至80°,其中-40°是下限值,80°是上限值,当指定关节的位置信息与-40°的差值的绝对值小于或等于5°时,则发出语音播报,语音播报的内容至少包括“第一机械臂中的指定关节即将到达下极限位置”,或者播报相类似的内容以提示医生和助手,当指定关节的位置信息与-40°的差值的绝对值大于5°时,则不发出语音播报。
参见图2,可选地,根据关节的位置信息与相应关节的上下极限值而判断是否发出相应关节的语音提示还包括:
若指定关节的位置信息与上下极限值中的上限值的差值的绝对值小于或等于第二设定值,则发出语音播报;
若指定关节的位置信息与上下极限值中的上限值的差值的绝对值大于第二设定值,则不发出语音播报。
这里,仍是以指定关节是属于第一机械臂中,指定关节是角度旋转关节,指定关节的角度范围为-40°至80°为例,其中-40°是下限值,80°是上限值,当指定关节的位置信息与80°的差值的绝对值小于或等于5°时,则发出语音播报,语音播报的内容至少包括“第一机械臂中的指定关节即将到达上极限位置”,或者播报相类似的内容以提示医生和助手,当指定关节的位置信息与-40°的差值的绝对值大于5°时,则不发出语音播报。
参见图3,可选地,腹腔镜手术机器人的语音提示控制方法还包括:
通过左操作手上的第一红外传感器获取左操作手到右操作手的第一距离;
通过右操作手上的第二红外传感器获取右操作手到左操作手的第二距离;
根据第一距离和/或第二距离判断是否发出语音播报。
这里,通过两个红外传感器实施检测左操作手与右操作手之间的最小距离,保证医生和助手即使将全部的注意力集中到末端器械,也不会发生两个主操作手发生碰撞的现象,进一步提高手术效率和手术成功率。
参见图3,可选地,根据第一距离和/或第二距离判断是否发出语音播报包括:
若第一距离小于或等于第三设定值,则发出语音播报;
若第一距离大于第三设定值,则判断第二距离与第三设定值的大小;若第二距离小于或等于第三设定值,则发出语音播报,若第二距离大于第三设定值,则不发出语音播报。
这里,只要第一距离和第二距离中任意一个小于或等于第三设定值3cm,就会发出语音播报,语音播报的内容至少包括“左操作手与右操作手即将发生碰撞”,或者播报相类似的内容以提示医生和助手。
另外,另一实施例还提供一种腹腔镜手术机器人的语音提示控制系统,包括:
获取单元,获取单元用于获取每个机械臂上多个标定点的实时空间位置,获取单元还用于获取机械臂中各个关节的位置信息,获取单元还用于通过左操作手上的第一红外传感器获取左操作手到右操作手的第一距离,获取单元还用于通过右操作手上的第二红外传感器获取右操作手到左操作手的第二距离;
控制单元,控制单元用于根据全部标定点的实时空间位置得到任意两个机械臂上各个对应位置之间的距离,控制单元还用于根据任意两个机械臂上各个对应位置之间的距离得到任意两个机械臂之间的最小距离,控制单元还用于根据任意两个机械臂之间的最小距离而判断是否发出语音播报;控制单元还用于根据关节的位置信息与相应关节的上下极限值而判断是否发出相应关节的语音提示;控制单元还用于根据第一距离和/或第二距离判断是否发出语音播报。
这里,基于腹腔镜手术机器人的语音提示控制系统组成简单、成本低、可靠性高且兼容性好。
虽然本公开披露如上,但本公开的保护范围并非仅限于此。本领域技术人员在不脱离本公开的精神和范围的前提下,可进行各种变更与修改,这些变更与修改均将落入本发明的保护范围。
