需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
根据本申请实施例,提供了一种用于手术机器人智能截骨***的监控方法,手术机器人上设置有摆锯,所述摆锯可在不同的摆频下运动。手术机器人的类型包括但是不限于用于膝关节置换手术中、或者用于其他手术中,通过带动摆锯运动实现切削动作的机器人。摆锯可以通过可拆卸的方式设置在手术机器人的机械臂上(包括但是不是限于机械臂的末端),通过摆锯的运动可以实现切削动作,摆锯运动的方式可以是在不同的摆频下(例如,频率1分钟可达5000-20000次),围绕中心点做大约3°-5°角度摆动的运动,运动方式在此不做限定。例如,在膝关节置换手术过程中,摆锯通过上述运动方式实现膝关节坏骨的切除,在切除后便可安装假体实现膝关节置换。
可以理解的是对于不同的手术类型,摆锯的规格可以是不同,例如摆锯的形状、大小、可达的最大摆频等等有所不同。不同类型的摆锯可适用于不同手术类型中。
当摆锯通过运动实现切削的过程中,锯片刀面克服摩擦所做的功转换为热量,而过高的切削热可能会损伤骨组织以及骨神经。因此监控摆锯的运动状态,减少由锯片和/或驱动***带来过高的切削热量,是保证手术能否成功、或者提高手术成功率、准确率的关键因素。
如图1所示,该方法包括如下的步骤101至步骤103:
步骤101:当摆锯进入工作状态后,对摆锯直流供电过程中的供电电流进行采集,其中,随着摆锯的摆频的变化,所述直流供电过程中电压不变。
在本实施例中,手术机器人中使用的摆锯可以通过直流供电电路进行供电,可通过AC/DC转换将交流电转换为直流电,供摆锯使用,由于摆 锯摆频可以是变化的,因此需要该供电电路AC/DC提供足够的功率,以保证电路中的电压稳定不变。
在采集时,可以通过设置的采集电路进行采集。示例性地,当摆锯进入工作状态后,电流变送器可将电路中的电流进行转换,例如,将2-30A转换为4-20mA的电流,转换后的电流可以通过预设设置的闭环电路的模拟量收集引脚进行采集。其中,闭环电路可用于采集电流信息,并将电流信息发送至预设对象;闭环电路还可以自动实现供电电路的开合,进而实现摆锯的工作和暂停。
步骤102:基于所述供电电流,确定控制信号。
在本实施例中,可通过供电电流确定工作电流,基于该工作电流确定控制信号;还可以基于当前供电电流确定产热量,基于产热量确定控制信号。
作为本实施例一种可选的实现方式,基于所述供电电流,确定控制信号,包括:基于所述供电电流,确定所述摆锯在当前工作状态下的工作用的产热量;基于所述产热量和预设产热量阈值,确定控制信号;或,基于供电电流,确定所述摆锯的工作电流;基于所述工作电流和预设工作电流阈值,确定所述控制信号。
在本可选的实现方式中,在采集供电电路的电流时,可以通过设置的闭环电路进行采集,该闭环电路是由电流变送器传输的,因此可通过采集的电流确定的工作电流,示例性的,采集的电流为毫安信号,因此可通过Y=1.875*(X-4)转换为安培信号,以4-20mA信号为例,通过Y=1.875*(X–4)转换为2-30A信号。通过确定工作电流、以及预设的工作电流阈值,确定控制信号,示例性地,可以通过确定工作电流与预设的工作电流的阈值之间的差量确定控制信号。
还可以通过供电电流以及热量计算公式确定当前工作状态下的工作用的产热量,基于该产热量与预设的产热量阈值的差量确定控制信号。
示例性地,基于所述工作电流,确定所述摆锯在当前工作状态下的工作用的产热量可以通过如下步骤确定:可预先测定摆锯在空载状态下的功率,而后基于该功率和总功率(该总功率可基于所述工作电流,确定 总功率)确定当前工作状态下的功率,进而可以得到该工作用的产热量,该产热量可以确定为手术切削过程的切削热。
进一步地,从功率消耗角度分析,摆锯消耗的有功功率分别转换为摆锯内部的损耗和骨切削时的摩擦热量损耗,P=U*I=P(内部损耗)+P(摩擦热量),其中,内部损耗即空载功率。
本可选的实现方式,通过确定切削热,能够保证摆锯在热量阈值范围内进行运动实现切削,保证了手术的安全性、以及避免了热量过高导致手术失败的问题,提高了手术的成功率。
可以理解的是,确定控制信号的可以是本实施例的执行主体,也可以是工控机,在确定控制信号后,将该控制信号包含的指令信息发送至摆锯的控制电路。
作为本实施例一种可选的实现方式,基于所述供电电流,确定控制信号,包括:若所述工作电流大于或等于预设工作电流阈值,则确定所述控制信号为用于降低摆锯摆幅的控制信号;若所述工作电流小于预设工作电流阈值,则确定所述控制信号为用于保持摆锯摆幅不变的控制信号;或,若所述产热量大于或等于预设产热量阈值,则确定所述控制信号为用于降低摆锯的摆幅的控制信号;若所述产热量小于预设产热量阈值,则确定所述控制信号为用于保持摆锯摆幅不变的控制信号。
在本可选的实现方式中,摆锯的控制电路可以包括主控制电路、电机、传动装置和锯片等。摆锯的运动可在控制电路控制下实现,控制电路中基于工控机发送的控制指令生成电机控制信号,在电机控制信号的控制下电机通过传动装置带动摆锯进行运动,电机不同的转速可对应至摆锯不同的摆频。通过上述控制方式可以保证摆锯在产热量安全的范围内运动。
步骤103:基于所述控制信号控制所述摆锯的摆频。
在本实施例中,控制电路在控制时可以是调整输出的脉宽信号,以得到不同频率交流信号,进而控制电机转速的变化,电机的转子可通过传动装置控制摆锯的摆频。
在手术中不良骨切削会在骨组织中产生较高的应力,同时会产生切削 热,如果切削热过大会无法保证锯切面骨组织活力。因此需要控制切削过程中的上限温度,例如为50℃-60℃等。
由此,可预先设定最大的切削热(预设产热量阈值),根据该热量可以计算出工作电流的最大阈值;进而可通过监测热量或者监测工作电流的方式,确定控制信号,由该控制信号控制电动机的转速,进一步实现控制摆频的目的。通过减小摆频,减小切削热,进而控制截骨过程中出现的风险,保证了手术的安全性。
可以理解的是,在摆锯锯切过程中,随着切削力或推力、摆频的增大,切削热呈线性关系增大,因此当切削热过大时,除可控制摆频调整外,还可通过减少手术机器人机械臂推力的方式减少切削热,减少推力的大小可基于不同的机械臂的结构,利用力学原理计算出来,进而可将当前推力自动调整至目标推力的大小。
作为本实施例一种可选的实现方式,不同型号的摆锯,产热量阈值或预设工作电流阈值不同;或,摆锯所作用的不同的手术部位,产热量阈值或预设工作电流阈值不同。
在本可选的实现方式中,不同规格的摆锯其在运动时的负载状态是不同的,因此可以针对不同型号的摆锯设置不同的产热量阈值,而通过该阈值可以进一步确定工作电流的阈值。
进一步地,摆锯所作用的不同手术部位,所允许的最大切削热也是不同的,因此,针对不同的手术部位可以确定产热量阈值,进而进一步确定工作电流的阈值。可以理解的是产热量的最大阈值确定依据仅仅是示意性地。
本实施例通过,恒压直流供电,实现摆锯在工作状态下的电流测定,基于该电流可以确定摆锯的切削热,实现了手术过程中摆锯的工作状态监控,提高了手术过程的安全性。
作为本实施例一种可选的实现方式,方法还包括:确定所述供电电流不为零时的时长;将所述时长与预设的临床信息对应存储。
在本可选的实现方式中,不同的个体对应的骨密度是不同,不同的骨 密度在一定切削热范围内,其切削时间也是不同的;而不同的切削时间也可以用于反向确定切削热的范围,基于该范围便可以确定最大的工作电流,从而便可以对摆锯的运动状态进行针对性地监控。因此确定摆锯在工作状态下,针对不同的骨密度等临床信息确定所需的工作时间(手术时间),对于提高手术精度具有重要的影响。
手术过程中可能存在因手术流程的需要,需暂时停止切削,以停止摆锯运动的情形、或者因手术过程存在异常,需暂时停止切削以停止摆锯运动的情形。因此可以通过确定的工作电流的大小,确定摆锯运动过程(对应手术截骨过程)的时间;而后将该时间与临床信息进行对应存储,该临床信息可以包括骨龄、骨密度。当同一类型的摆锯针对任一相似或相同的临床信息进行术前准备时,便可以直接确定该次手术所需的时间、所允许的最大切削热、以及所允许的最大工作电流。
本实施例通过监控工作电流,避免出现过高的切削热,保证了手术过程的安全性和精准性。
需要说明的是,在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机***中执行,并且,虽然在流程图中示出了逻辑顺序,但是在某些情况下,可以以不同于此处的顺序执行所示出或描述的步骤。
