技术领域
本公开涉及牙科治疗器械技术领域,具体涉及一种根管治疗设备。
背景技术
人的牙齿中包含有牙髓腔,还有1-4个根管,通过根管导出牙神经和营养神经的血管,当牙髓中因为各种情况发生感染都会导致牙齿的功能性损伤,并且会造成疼痛以及颌骨感染等病痛。根管治疗又称为牙髓治疗,是近年来发展起来的一种保护患牙的治疗方法,对于慢性牙髓炎、慢性根尖周炎、牙周牙髓联合病变以及外伤牙等牙科问题有较好的治疗和保护作用。
根管治疗包括根管预备、消毒以及根管充填等几个主要的治疗阶段,根管预备和消毒是对牙根管进行机械切割和扩锉以达到所需的塑形,为后续根管充填创造较好的空间条件,通过冲洗去除根管内的有机物质和根管的感染组织(细菌),完成根管清创后,向根管内填充药物材料,使填充的药物材料与根管壁贴合。
现有技术中对于根管的正压冲洗难以保证对根管下端的充分清理,导致根管下端的部分有机物质和感染组织难以充分的清出,而且导致根管清洗时间过长,患者口腔长时间张开,延长了患者的痛苦时间,而且,由于根管清洗后向根管内填充的药物材料通常是粉末和水调和而成的糊状材料,药物材料在调和的过程中难以避免的会混入气泡,通过超声荡洗器荡洗的方式对于药物材料中气泡的排除效果不佳,混在药物材料中的气泡会影响到药物材料与根管壁贴合的紧密性。

具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述。
在本公开的描述中,需要说明的是,术语“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系,或者是该申请产品使用时惯常摆放的方位或位置关系,仅是为了便于描述本公开和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本公开的限制。此外,术语“第一”、“第二”等仅用于区分描述,而不能理解为指示或暗示相对重要性。
还需要说明的是,除非另有明确的规定和限定,术语“设置”、“连接”应做广义理解,例如,可以是固定连接,也可以是可拆卸连接,或一体地连接;可以是直接相连,也可以通过中间媒介间接相连,可以是两个元件内部的连通。对于本领域的普通技术人员而言,可以具体情况理解上述术语在本公开中的具体含义。
在进行牙根管治疗手术的过程中,需要首先对牙根管进行预备成型和荡洗清理,预备成型是为了提供准确的塑形效果,保证后续处理的工作空间,根管预备成型主要是通过根管锉在根管中高速转动,削磨根管的内壁达到的。荡洗清理则是为了将根管内原先的病变组织以及细菌等物质进行清理,通常是通过加压的方式对根管进行持续冲洗,难以对根管下段进行有效的清洗,而且,现有的根管荡洗设备的锉针通常是不锈钢或钛合金锉针,这些材质的锉针质地较硬,往往只能对直根管或弯曲根管中部及偏下位置进行有效的清洁荡洗,对复杂弯曲根管的根尖部位清洁效果不佳。若采用正压和负压联动的方式冲洗,又会增加结构的复杂性以及设备成本。还可以采用更换工作设备并使设备中的挫针以超声频率在根管中振动的方式,通过声流效应和空穴效应,对充填的药物材料中的气泡进行有效的排除,但是这种方式需要对工作设备进行多次更换,根管治疗中上述的过程往往需要根据病情需要相互穿插调换使用,频繁的更换治疗工作设备,使得操作不便,且手术效率低。
基于此,本公开实施例提供了一种根管治疗设备,图1为本公开一些实施例中提供的一种根管治疗设备的结构示意图之一,如图1所示,本公开实施例提供的根管治疗设备包括弯手机10以及与弯手机10可拆卸连接的根管锉20,还包括与根管锉20传动连接的驱 动模组30,驱动模组30包括旋转驱动器31(图1中未示出)以及振动发生器32,旋转驱动器31配置成驱动根管锉20轴向转动,振动发生器32配置成驱动根管锉20径向振动。
如图1所示,本公开实施例提供的根管治疗设备,弯手机10配置成设置在手柄件上,并且进行必要的线路连接,通过操作控制驱动模组30中的旋转驱动器31以及振动发生器32的工作,使得根管锉20形成相应的工作模式,以分别对根管进行对应操作。其中,旋转驱动器31配置成驱动根管锉20旋转,根管锉20头部为尖端,配置成伸入根管内部,当根管锉20以一定的速度自转旋转时,根管锉20侧壁触碰的根管内壁即能够通过根管锉20的打磨形成所需的形状。而且,在根管中注入如次氯酸钠等的溶液进行根管荡洗的过程中,以及在荡洗后向根管中充填糊状填充材料的过程中,都仍需要旋转驱动器31的旋转作用驱动根管锉20转动,来实现充分的荡洗和充填。通常,糊状填充材料是采用如生物陶瓷或者三氧矿物聚合物的药剂粉末与水混合制备而成,在糊状填充材料的制备过程中难以避免的会混入空气形成气泡,在将糊状填充材料填充至根管中时,还需要尽可能对这些气泡进行清除,以使得药物材料能够尽可能的在根管中紧密填充,这种情况下在根管锉20转动的同时,控制振动发生器32驱动根管锉20沿根管锉20的径向以预设频率振动,根管锉20转动结合振动,能够有助于填充药物的活性激发,并快速高效的排出气泡。或者还可以在根管荡洗或者根管充填的过程中单独控制振动发生器32驱动根管锉20振动,从而使得根管锉20的工作方式多样化,减少根管治疗手术中工作设备更换造成的操作不便,能够配合根管治疗的各个步骤所需,有效的提高根管治疗的效率和效果。
需要说明的是,第一,由于旋转驱动器31通常设置于弯手机10内,在图1中未示出旋转驱动器31的位置及结构,示例的,旋转驱动器31可以为旋转电机,旋转电机的输出端作用于弯手机10头部的转动轴上,通过转动轴带动根管锉20转动,转动可以是单向也可以是往复转动,转速可在50-3000rpm之间根据需要进行设置,本实施例中均不作具体限定,本领域技术人员可根据需要进行相应的设置和操作。
第二,本公开实施例中对于振动发生器32的具体实现结构形式也不做具体限定,振动发生器32作为驱动模组30的一部分,配置成作用于根管锉20,以使根管锉20受驱径向振动,而且,由于是应用于人体口腔内牙根管的手术操作,振动发生器32输出的振动的频率通常较大,振幅较小,主要以能够在根管治疗过程中辅助根管内的清理和药液的激活为目的。振动的振幅和频率在本公开实施例中未进行具体的范围限定,只要是在能够满足上述目的基础上,本领域技术人员可以根据实际工作需要进行相应的设置和操作。
根管锉20配置成伸入牙根管内进行旋转或者还包括振动的削磨,示例的,根管锉20采用镍钛合金材质制作,镍钛合金的材质相对柔软且柔韧性好,当加工为根管锉20时,根 管锉20伸入形状可能不规则的根管中,镍钛合金制作的根管锉20能够在一定程度范围内形变以适应于根管的实际形状,从而使得根管锉20能够伸入根管深处,实现更好的根管塑形和清洗效果。
而且,图1中,振动发生器32设置在弯手机10的外壁上仅为一种示例性的结构示意,本公开实施例中对此并不做具体限定,例如,也可以设置在弯手机10内,或者手柄件等结构上。
根管锉20与弯手机10之间可拆卸连接,根管锉20与弯手机10之间的可拆卸连接方式可以包括磁性吸合、卡接设置和/或螺纹紧固连接件连接等,由于弯手机10端部安装不同的工作头能够对应进行多种牙科手术的相关操作,因此,可拆卸连接方式,有助于本公开实施例的根管治疗设备在使用中进行工作头的更换使用。
本公开实施例提供的一种根管治疗设备,包括弯手机10以及与弯手机10可拆卸连接的根管锉20,还包括与根管锉20传动连接的驱动模组30,驱动模组30包括旋转驱动器31以及振动发生器32,旋转驱动器31配置成驱动根管锉20轴向转动,以对根管进行机械切割和扩锉,从而对根管进行塑形成形,振动发生器32配置成驱动根管锉20径向振动,根管锉20以特定的频率振动,能够使根管内药液填充的更紧密,特别是在对根管荡洗以排出药液的过程中,结合根管锉20的旋转与振动共同进行,能够高效的排出充填在根管中的药剂气泡,使得药液紧密的充填根管,为后续根管治疗提供较佳的环境,提高根管治疗的效果,减轻患者的痛苦。
图2为本公开一些实施例中提供的一种根管治疗设备的结构示意图之二,如图2所示,可选的,根管治疗设备还包括与弯手机10连接的手柄40,旋转驱动器31设置在手柄40内且旋转驱动器31通过弯手机10驱动根管锉20旋转,振动发生器32设置在手柄40上,振动发生器32的振动端作用于根管锉20。
根管治疗设备通常包括与弯手机10连接的手柄40,手柄40通常采用便于手持操作的外形结构,根管治疗设备中所需的线路走线以及功能器件均设置于手柄40内,并且在手柄40上设置相应的控制键,手术时,便可通过对手柄40上相应控制键的操控,使得根管治疗设备执行相应的工作,从而尽可能的简化本公开实施例的根管治疗设备的操作,使得操作更方便。
在设置有手柄40的根管治疗设备中,驱动模组30中的旋转驱动器31和振动发生器32均设置于手柄40处,其中,旋转驱动器31设置在手柄40的中空结构内部,旋转驱动器31的输出端传动至弯手机10内的转动轴,以带动根管锉20转动,振动发生器32设置在手柄40上,振动发生器32的振动端直接作用于根管锉20,以便准确的实现振动的驱动。
示例的,如图2所示,本公开实施例的一种可实现的方式中,振动发生器32为超声换能器。
超声换能器是一种将电磁能转化为机械能(声能)的装置,通常由压电陶瓷或其它磁致伸缩材料制成,超声换能器输出的超声振动能够在20-60KHZ的频率下以15-120微米的振幅持续输出振动。在本实施例中,振动发生器32为超声换能器,通过超声换能器提供根管锉20振动的机械能,超声换能器的工作稳定,且尺寸大小也能够匹配于本公开实施例的根管治疗设备上,是振动发生器32的一种较好的实现形式。
具体的,图3为本公开实施例的根管治疗设备中振动发生器为超声换能器的结构示意图,在本公开实施例的一种可实现的方式中,如图3所示,超声换能器包括外壳321以及设置在外壳321内的换能器本体322,外壳321与手柄40一体成型。
超声换能器的外壳321与手柄40之间一体成型制作,例如,外壳321与手柄40均采用塑性材料,通过注塑成型为一体,或者,若外壳321与手柄40采用金属材料,将二者通过焊接等方式连为一体,一体成型的连接方式使得手柄40与超声换能器的外壳321之间具有更好的结构稳定性,超声换能器启动产生振动时,一体成型的结构不易发生裂缝或断裂的问题,且对于振动的传递损失也较小。
又例如,外壳321与手柄40还可以通过螺纹紧固连接件或卡接件可拆卸连接。即,外壳321与手柄40为分别的壳体结构,两者之间可拆卸连接,其中可拆卸连接的方式可以根据需要选择螺纹紧固连接件进行螺纹连接,螺纹连接的方式进行固定较为稳定,或者,选择过盈配合的方式卡接,选择卡扣连接的方式卡接等,用卡接的方式更换起来更加方便快捷,再或者,还可以是其他的可拆卸连接方式,总之,对于外壳321和手柄40之间采用可拆卸连接的方式,便于对振动发生器32的拆卸和调整,使用方便。
图4为本公开一些实施例中提供的根管治疗设备中超声换能器与根管锉之间通过振动连接器连接的结构示意图,如图4所示,在本公开实施例的一种可实现的方式中,在超声换能器与根管锉20之间还设置有振动连接器50,超声换能器通过振动连接器50与根管锉20连接。
由于超声换能器设置在手柄40上,与根管锉20之间具有一定的距离,为了提高超声换能器的振动的传递效率,以及的振动的传递过程中保证振动的参数要求,在超声换能器与根管锉20之间设置振动连接器50,振动连接器50配置成将超声换能器中输出的振动传递至根管锉20并直接作用于根管锉20,通常情况下,为了有效的将超声换能器的振动传递给根管锉20,振动连接器50为硬质材料制备加工而成,但是,考虑到振动直接作用于根管锉20上,为了尽可能的避免振动作用于根管锉20对于根管锉20的损伤,可以在振动 连接器50作用于根管锉20的一端设置相应的保护结构,本公开实施例中对于采用何种保护结构不做具体限定,示例的,结构方面,可以设置与根管锉20之间尽可能大的作用表面,可以设置与根管锉20的结构相贴合的作用表面,材料方面,也可以为将作用面设置为具有一定缓冲能力的材料等。而且,由于弯手机10通常具有一定的弯曲角度,通过振动连接器50将手柄40上设置的超声换能器的振动传递至根管锉20使根管锉20径向振动,还能够设置振动连接器50具有相配合的弯曲形态,从而尽可能保证振动力的准确传递。
图5为本公开一些实施例中提供的根管治疗设备中振动连接器的结构示意图之一,如图5所示,在本公开实施例的一种可实现的方式中,振动连接器50与根管锉20连接的一端设置有振动头501,振动头501配置成与根管锉20连接的端面呈内凹的圆弧面。
根管锉20通常为圆柱形且工作端侧面为便于挫磨的粗糙表面,端部为针尖结构,与之对应的,需要直接作用于根管锉20侧面以传递振动振动连接器50的振动头501,其与根管锉20连接的端面呈内凹的圆弧面,这样一来,传递振动时,二者之间的接触面较为匹配,且接触面积大一些,避免传递的振动作用于很小的区域,从而减轻根管锉20的振动劳损,提高根管锉20的使用寿命。
具体的,振动头501的圆弧面直径大于或等于根管锉20的直径。这样一来,振动头501在传递振动力时,圆弧面能够将根管锉20部分包覆或者半包覆,更加有效且准确的传递振动力。
图6为本公开一些实施例中提供的根管治疗设备中振动连接器的结构示意图之二,在本公开实施例的一种可实现的方式中,如图6所示,振动连接器50包括端部相互套接的第一连接杆51和第二连接杆52,以及套接在第一连接杆51的套接端的紧固件53,紧固件53配置成固定第一连接杆51和第二连接杆52的套接端。
为了提高振动连接器50对于不同型号根管治疗设备的实用性,以及在使用根管治疗设备进行手术操作时,可能需要的尺寸调整,振动连接器50可以设置为两段可调节式的结构。第一连接杆51和第二连接杆52通过端部相互套接,如图6所示,第一连接杆51和第二连接杆52通过相互配合的螺纹内外套接,从而能够通过改变第一连接杆51和第二连接杆52的总长度来调节振动连接器50的伸缩长度,调节至合适的长度后,通过紧固件53套接在第一连接杆51和第二连接杆52的套接端进行固定,既能够调节长度,又能够便于固定,其中,振动头501设置在振动连接器50靠近根管锉20的第一连接杆51端部。示例的,当使用本公开实施例的根管治疗设备进行其他治疗时,可以不必将振动连接器50整体拆卸,只松去紧固件53后,去除第一连接杆51即可。
图7为本公开一些实施例中提供的根管治疗设备中振动连接器的结构示意图之三,在 本公开实施例的一种可实现的方式中,如图7所示,第一连接杆51配置成与根管锉20连接的另一端还可拆卸连接有连接座54,连接座54与第一连接杆51之间穿设有固定件55。
第一连接杆51还可拆卸的设置有连接座54,第一连接杆51和连接座54之间通过固定件55固定,第一连接杆51和连接座54之间也相互套接可调节距离,如图7所示,可以将第一连接杆51的端部设置为通槽的结构,与之对应的,连接座54包括伸入通槽内的部分,通过调节连接座54伸入通槽内部分的长度,能够调节第一连接杆51和连接座54之间的总长度,也便能够调节振动连接器50的总长度,如图7所示,振动连接器50通常是配合于弯手机10形成的弯折结构,因此,在振动连接器50的两侧均设置能够调节长度的分段结构,在能够调节振动连接器50的总长度的同时,还能够一定程度上调节振动传递的方向,从而提供更能够适应各种临床需要的结构。同样的,在使用本实施例的根管治疗设备进行其他治疗时,可以不必将振动连接器50整体拆卸,只松去紧固件53后,去除第一连接杆51即可。
在本公开实施例的一种可实现的方式中,在超声换能器与根管锉20之间还设置有镍钛连接杆,超声换能器通过镍钛连接杆与根管锉20连接。
镍钛材料的材质较软,且柔韧性较好,将镍钛材料采用特定的热处理工艺制备的镍钛连接杆具有一定程度的塑性形变能力,设置在超声换能器与根管锉20之间,能够在与根管锉20抵持的状态下有效的传递超声换能器提供的振动力,且能够根据临床需求手动弯曲调整镍钛连接杆的角度、连接位置和与根管锉20之间抵持的松紧程度。本公开实施例中对于镍钛连接杆未示出附图,其形状结构可以参照如图4中一体设置的振动连接器50,只是材料选用前述的镍钛材料既能够实现前述功能。
图8为本公开一些实施例中提供的根管治疗设备中振动发生器为震动器的结构示意图,图9为图8的局部放大图,在本公开实施例的一种可实现的方式中,如图8和图9所示,振动发生器32为震动器,震动器包括塑性壳体323以及设置在塑性壳体323内的震动马达324,震动器通过塑性壳体323固定于弯手机10上;震动马达324的震动输出端通过弹性件325连接有顶紧块326,顶紧块326通过塑性壳体323上开设的开口伸出于塑性壳体323外,且在根管锉20的侧壁与根管锉20抵持。
如图9所示,振动发生器32为震动器,通过震动马达324提供振动的动力,震动马达324设置在塑性壳体323内,塑性壳体323具有一定的形变能力,塑性壳体323固定于弯手机10上,示例的,震动马达324与塑性壳体323之间可以通过胶水粘贴,或者通过过盈配合的卡接方式固定,震动马达324的震动输出端传输的振动力通过塑性壳体323向顶紧块326传递,顶紧块326通过塑性壳体323上开设的开口伸出至塑性壳体323之外,与根 管锉20的侧壁抵持,弹性件325可以为如图9中所示的弹簧,也可以为其他的具有弹性的连接件,通过弹性件325的设置,能够使得传输至根管锉20的振动力具有一定的缓冲,在传输振动力的同时对根管锉20进行有效的保护。
图10为图9中区域A的局部放大图,如图10所示,为了避免顶紧块326在震动马达324的振动力过大时可能由塑性壳体323中弹出的风险,在顶紧块326上形成有勾部3261,勾部3261配置成与塑性壳体323的开口的内壁卡接,以限制顶紧块326伸出开口的长度。这样一来,顶紧块326在伸出塑性壳体323的极限长度位置处,通过勾部3261与塑性壳体323的开口的内壁卡接限位,从而保证顶紧块326不会由塑性壳体323中脱出,保证了工作的安全性。
如图9所示,在本公开实施例的一种可实现的方式中,塑性壳体323上设置有减震橡胶垫327,塑性壳体323与弯手机10之间通过减震橡胶垫327卡接固定。
如图9所示,为了避免震动马达324的振动力直接传递到与塑性壳体323连接的弯手机10上,一方面导致振动力的无效损失,另一方面也会使得操作时握持本公开实施例的根管治疗设备的手承受不良的振动感,在塑性壳体323上还设置有减震橡胶垫327,用来阻隔塑性壳体323上的振动力向弯手机10的传递。其中,减震橡胶垫327在塑性壳体323上的设置尺寸,以及减震橡胶垫327的设置厚度在本公开实施例中均不作具体限定,本领域技术人员可以根据需要进行对应设置。
在本公开实施例的一种可实现的方式中,震动器还包括设置在手柄40内的电源,电源通过导线与震动马达324电连接,配置成为震动马达324供电。
电源设置于手柄40中,电源通过导线为震动马达324供电,使得本公开实施例的根管治疗设备在使用时更为方便拿取和移动,其中,当旋转驱动器31为电机时,电源也可以为电机供电,从而避免接入多个电源导致本公开实施例的根管治疗设备的尺寸较大,内部的部件设置冗余,结构不够紧凑。
需要说明的是,本公开实施例中对于电源的形式也不做具体限定,例如,可以是通过接口连接的市电交流电,可以是直流电,也可以是蓄电池等电量储存和输出部件。
图11为本公开一些实施例中提供的根管治疗设备的控制关系示意图,在本公开实施例的一种可实现的方式中,如图11所示,本公开实施例的根管治疗设备还包括控制器60,控制器60分别与旋转驱动器31和振动发生器32电连接,配置成分别控制旋转驱动器31和振动发生器32的工作。
这样一来,当本公开实施例的根管治疗设备中还包括控制器60,且控制器60分别与旋转驱动器31和振动发生器32电连接时,控制器60能过分别控制旋转驱动器31和振动 发生器32的工作。可以在手柄40上设置对应于控制器60中不同控制信号的案件,示例的,在手柄40上分别设置旋转启动键,振动启动键,以及旋转震动键,使用本公开实施例的根管治疗设备进行根管治疗手术时,操作者只需要在不同的治疗阶段,通过按动手柄40伤对应的按键,使得根管治疗设备仅旋转驱动器31启动工作,呈现根管锉20仅旋转进行根管清洗和塑性工作,或者,使得根管治疗设备仅振动发生器32工作,呈现根管锉20仅振动以对根管内填充的药液充分激活的工作,又或者,使得根管治疗设备中的旋转驱动器31和振动发生器32同时工作,呈现根管锉20既旋转也振动的状态,对根管内填充的药液产生的气泡进行充分的清洗和排出。
在此基础上,需要说明的是,在本公开实施例的根管治疗设备中,还可以包含有根管长度测量传感器,配置成测量当前治疗的根管的长度,当根管锉20旋转运动到根尖止点后,根管长度测量传感器感测到相应的信号并传输至控制器60中,控制器60根据根管长度测量传感器的检测信号向旋转驱动器31发出相应的反转、止停或者减速信号。
以及,本公开实施例的根管治疗设备中还可以集成其他的现有技术中根管治疗设备需要实现的其他结构以实现相应的功能。
以上所述仅为本公开的实施例而已,并不用于限制本公开的保护范围,对于本领域的技术人员来说,本公开可以有各种更改和变化。凡在本公开的精神和原则之内,所作的任何修改、等同替换和/或改进等,均应包含在本公开的保护范围之内。
