Description

内窥镜旋钮制动装置、内窥镜手柄及内窥镜 技术领域
本发明涉及医疗器械技术领域，特别是涉及内窥镜旋钮制动装置、内窥镜手柄及内窥镜。
背景技术
内窥镜是一种集传统光学、人体工程学、精密机械、现代电子、数学、软件等于一体的检测仪器，具有图像传感器、光学镜头、照明光源、机械装置等，其作为一种检测人体内部器官病变的重要辅助医疗仪器，广泛应用于各种外科手术中。目前内窥镜产品多为重复利用产品，每次使用后，需要经严格的消毒程序进行消毒。传统的内窥镜包括手柄、插入管、蛇骨、先端头和主机。手柄内集成有功能按钮、气水阀、负压阀、三通阀等结构。
为了扩大观察范围，通过旋钮装置控制蛇骨向四个方向弯曲，以实现内窥镜四向观察。当需获取特定方位上的图像信息时，通过制动组件，锁紧旋钮装置，以使蛇骨保持特定弯曲角度。传统的制动组件通常包括拨杆部和阻尼片，拨杆部上设有连接柱，阻尼片上设有弧形槽。当拨杆部旋转时，带动连接柱在弧形槽内由弧形槽初始状态下距离导轨件的轴线最远的一端滑动至弧形槽初始状态下距离导轨件的轴线最近的一端运动，驱使阻尼片相互靠拢，夹紧旋钮装置实现制动。然而，这种制动方式其结构设计复杂，成本较高，装配不便；同时，在制动过程中，制动力由连接柱与弧形槽间接配合传递，导致制动效果不佳。
发明内容
基于此，有必要提供一种结构设计简单、装配便利且制动效果较佳的内窥镜旋钮制动装置、内窥镜手柄及内窥镜。

在其中一个实施例中，所述制动件包括主体部及分别设于所述主体部相对两端的抱紧部与传动部，所述抱紧部位于所述第一槽段内，所述传动部位于所述第三槽段内，并部分伸出所述固定架外，所述第一槽段与所述第二槽段、所述第二槽段与所述第三槽段之间均具有限位壁，所述主体部滑动装设于所述第二槽段内，并分别与所述第一槽段与所述第二槽段、所述第二槽段与所述第三槽段之间的限位壁限位配合。
在其中一个实施例中，所述第一槽段的宽度W 1和所述第三槽段的宽度W 3均小于所述第二槽段的宽度W 2，以使所述第一槽段与所述第三槽段分别和所述第二槽段之间形成所述限位壁；所述抱紧部的宽度W 4和所述传动部的宽度W 6均小于所述主体部的宽度W 5。
在其中一个实施例中，所述制动钮包括钮本体与设于钮本体上的环套，所述环套套设于所述固定架外，所述推动部设于所述环套的内壁上。
在其中一个实施例中，所述推动部由所述环套的内壁朝所述环套的中心凸起形成。
在其中一个实施例中，所述制动钮上设有拨动部，所述拨动部沿着所述制动钮的径向凸起延伸；或者，所述制动钮上设有拨动部，所述拨动部沿着背离所述固定架的方向凸起延伸。
在其中一个实施例中，所述固定架上设有第一定位部，所述第一定位部用于与旋钮装置上的第二定位部定位配合，以限制所述固定架随所述旋钮装置旋转。
在其中一个实施例中，所述第一定位部为固定架上的定位槽或者定位凸起。
在其中一个实施例中，所述第一定位部为多个，多个所述第一定位部围绕 所述工作腔间隔排布。
在其中一个实施例中，所述制动钮上设有弧形槽，所述弧形槽围绕所述工作腔设置，所述弧形槽用于与壳体上的限位柱配合，以限制所述制动钮的旋转范围；或者，所述制动钮的内壁上设有第一限位块，所述固定架的外壁上设有第二限位块，所述第一限位块与所述第二限位块配合，以限制所述制动钮的旋转范围。
一种内窥镜手柄，所述内窥镜手柄包括旋钮装置及两个以上任意一项所述的内窥镜旋钮制动装置，所述旋钮装置包括壳体、第一拉线轮、第二拉线轮、第一旋钮及第二旋钮，所述第一拉线轮伸出所述壳体外与所述第一旋钮连接，所述第二拉线轮贯穿所述第一拉线轮伸出所述壳体外，并与所述第二旋钮连接，一个所述内窥镜旋钮制动装置用于对所述第一旋钮或所述第一拉线轮制动，另一个所述内窥镜旋钮制动装置用于对所述第二旋钮或所述第二拉线轮制动。
上述的内窥镜手柄，采用以上的内窥镜旋钮制动装置，将制动件一一对应滑动设于滑槽内，并保证制动件穿过滑槽伸出固定架外。当套在固定架外的制动钮旋转至预设角度时，其内壁上的推动部会与制动件接触、并推动制动件在滑槽内移动。由于滑槽与工作腔连通，因此，各个制动件在推动部的推动下分别朝工作腔内伸入，并最终抱紧在旋钮装置上，以实现旋钮装置的制动。如此，通过制动件与制动钮之间的配合结构，在制动过程中直接驱使制动件在滑槽内移动，便可实现旋钮装置的制动，其结构设计巧妙、简洁，制动力传递直接、有效，保证旋钮制动效果更佳。同时，在装配时只需将制动件滑动设于滑槽内，这样有效简化装配工序，有利于提高装配效率。

具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本发明。但是本发明能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下做类似改进，因此本发明不受下面公开的具体实施例的限制。
在一个实施例中，请参考图1与图6，一种内窥镜旋钮制动装置100，内窥镜旋钮制动装置100包括：固定架110、制动件120和制动钮130。固定架110上设有工作腔111。工作腔111用于供旋钮装置300穿入。固定架110上围绕工作腔111间隔设有至少两个滑槽112。各个滑槽112一端与工作腔111连通，另一端用于连通至固定架110外。制动件120为至少两个，各个制动件120一一对应地滑动装设于各个滑槽112内，制动件120穿过滑槽112并伸出固定架110 外。制动钮130套设于固定架110外，制动钮130的内壁上间隔设有至少两个推动部133，制动钮130旋转至预设角度时，各个推动部133一一对应地推动各个制动件120朝工作腔111的方向移动，以抱紧旋钮装置300。
上述的内窥镜旋钮制动装置100，将制动件120一一对应滑动设于滑槽112内，并保证制动件120穿过滑槽112伸出固定架110外。当套在固定架110外的制动钮130旋转至预设角度时，其内壁上的推动部133会与制动件120接触、并推动制动件120在滑槽112内移动。由于滑槽112与工作腔111连通，因此，各个制动件120在推动部133的推动下分别朝工作腔111内伸入，并最终抱紧在旋钮装置300上，以实现旋钮装置300的制动。如此，通过制动件120与制动钮130之间的配合结构，在制动过程中直接驱使制动件120在滑槽112内移动，便可实现旋钮装置300的制动，其结构设计巧妙、简洁，制动力传递直接、有效，保证旋钮制动效果更佳。同时，在装配时只需将制动件120滑动设于滑槽112内，这样有效简化装配工序，有利于提高装配效率。
需要说明的是，“预设角度”应理解为：在需对旋钮装置300制动时，制动钮130绕旋转轴线沿顺时针或逆时针转动一定的角度后，制动钮130上的推动部133则推动制动件120在滑槽112内朝工作腔111移动。该角度可取0°(不包括0°)～360°(不包括360°)中任一角度值。
还需说明的是，当旋钮装置300穿入工作腔111时，旋钮装置300可穿过制动钮130，也可不穿过制动钮130，即制动钮130盖在旋钮装置300上。另外，至少两个制动件120在抱紧旋钮装置300时，制动件120的一端应设计为能与旋钮装置300外轮廓配合的，以使其能限制旋钮装置300继续转动。当然，为了提高抱紧效果，可在制动件120的一端设置防滑结构，比如：增加防滑齿、防滑纹、防滑阻尼层等。
进一步地，请参考图3，滑槽112包括依次连通的第一槽段1121、第二槽段1122和第三槽段1123。第一槽段1121与工作腔111连通。第三槽段1123用于连通至固定架110外，制动件120滑动装设于第二槽段1122内，且制动件120一端伸至第一槽段1121内，另一端穿过第三槽段1123并伸出固定架110外。本实施例将滑槽112设计成三段结构，在制动之前，制动件120一端穿过第三槽段1123伸出固定架110外；在制动时，制动件120在推动部133的作用下，另一端穿过第一槽段1121伸入工作腔111内，以抱紧旋钮装置300。
更进一步地，请参考图3，制动件120包括主体部121及分别设于主体部121相对两端的抱紧部122与传动部123。抱紧部122位于第一槽段1121内。传动部123位于第三槽段1123内，并部分伸出固定架110外。第一槽段1121与第二槽段1122、第二槽段1122与第三槽段1123之间均具有限位壁1124。主体部121滑动装设于第二槽段1122内。并分别与第一槽段1121与第二槽段1122、第二槽段1122与第三槽段1123之间的限位壁1124限位配合。在限位配合中，当主体部121与邻近第三槽段1123的限位壁1124配合时，传动部123则部分穿过第三槽段1123伸出固定架110外；当主体部121与邻近第一槽段1121的限位壁1124配合时，抱紧部122穿过第一槽段1121伸入工作腔111内。如此，利用第一槽段1121与第二槽段1122、第二槽段1122与第三槽段1123之间的限位壁1124，限制主体部121在第二槽段1122内的移动行程，在实现有效制动的前提下，避免制动件120滑出滑槽112外而导致内窥镜旋钮制动装置100失效。
可选地，抱紧部122与传动部123分别在主体部121上的连接方式可为但不仅限于螺栓连接、螺纹套接、卡接、焊接、铆接、销接、一体成型方式等。其中，一体成型方式应理解为：注塑成型方式、挤压成型方式、压铸方式等。
具体地，请参考图4与图8，传动部123、主体部121及抱紧部122为一体 式结构，这样不仅有利于简化制作工序，而且还有利于保证制动件120的结构稳定。
当然，制动件120为一体式结构时，其外形设计可有多种选择，比如：山字型等。对此，本实施例不作具体限定。
在一个实施例中，请参考图3，第一槽段1121的宽度W 1和第三槽段1123的宽度W 3均小于第二槽段1122的宽度W 2，以使第一槽段1121与第三槽段1123分别和第二槽段1122之间形成所述限位壁1124。抱紧部122的宽度W 4和传动部123的宽度W 6均小于主体部121的宽度W 5。由此可知，在制动过程中，利用第二槽段1122分别与第一槽段1121、第三槽段1123之间的宽度差，形成两侧的限位壁1124，将主体部121稳定限制在第二槽段1122内来回移动，保证制动结构更加稳定。
需要说明的是，第一槽段1121设于第二槽段1122的中部，利用第一槽段1121与第二槽段1122之间的宽度差，可形成两个限位壁1124，当然第一槽段1121不设于第二槽段1122的中部也可形成一个限位壁1124。同理，第三槽段1123设于第二槽段1122的中部，利用第三槽段1123与第二槽段1122之间的宽度差，可形成两个限位壁1124，当然第三槽段1123不设于第二槽段1122的中部，也可形成一个限位壁1124。
在一个实施例中，请参考图1与图5，制动钮130包括钮本体131与设于钮本体131上的环套132。环套132套设于固定架110外，推动部133设于环套132的内壁上。如此，当驱使环套132在固定架110外旋转时，其内壁上的推动部133会与制动件120伸出的部分接触，并推动制动件120移动。
可选地，推动部133在环套132上的连接方式可为但不仅限于螺栓连接、螺纹套接、卡接、焊接、铆接、销接、一体成型方式等。
需要说明的是，钮本体131上可设置供旋钮装置300穿设的穿孔，以便装配。
进一步地，请参考图1与图5，推动部133由环套132的内壁朝环套132的中心凸起形成，即推动部133与环套132为一体式结构，这样使得其制作更加便捷。
具体地，请参考图1与图5，推动部133、制动件120及滑槽112均为三个。三个滑槽112绕工作腔111的周向间隔设置。三个推动部133沿着环套132的周向间隔设置。
在一个实施例中，请参考图2与图6，制动钮130上设有拨动部134。拨动部134沿着制动钮130的径向凸起延伸；或者，拨动部134沿着背离固定架110的方向凸起延伸。由此可知，本实施例提供两种不同结构的拨动部134，通过设计不同的拨动部134，便于作业人员驱使制动钮130旋转，以提升产品的可操作性。
在一个实施例中，请参考图2与图7，固定架110上设有第一定位部113。第一定位部113用于与旋钮装置300上的第二定位部220定位配合，以限制固定架110随旋钮装置300旋转，如此，通过第一定位部113和第二定位部220配合，使得固定架110处于相对固定状态，以便制动件120抱紧旋钮装置300。
可选地，第一定位部113为凸状结构，第二定位部220为孔或槽状结构；或者，第一定位部113为孔或槽状结构，第二定位部220为凸状结构。
进一步地，请参考图2与图7，第一定位部113为固定架110上的定位槽1131或者定位凸起1132。
具体地，请参考图9，一个固定架110上的第一定位部113为定位槽1131，与壳体200上的第二定位部220定位配合。另一个固定架110上的第二定位部 220为定位凸起1132，与拉线轮支架500上的第二定位部220定位配合。
更进一步地，请参考图2与图7，第一定位部113为多个。多个第一定位部113围绕工作腔111间隔排布，如此，通过多个第一定位部113与多个第二定位部220配合，使得固定架110的旋转限制效果更佳。
在一个实施例中，请参考图2与图5，制动钮130上设有弧形槽135。弧形槽135围绕工作腔111设置，弧形槽135用于与壳体200上的限位柱210配合，以限制制动钮130的旋转范围；或者，制动钮130的内壁上设有第一限位块136，固定架110的外壁上设有第二限位块114，第一限位块136与第二限位块114配合，以限制制动钮130的旋转范围。如此，通过弧形槽135或者第一限位块136，有效限制制动钮130的旋转范围，避免过度旋转而导致结构失稳。
在一个实施例中，请参考图9，一种内窥镜手柄，内窥镜手柄包括旋钮装置300及两个以上任意一实施例中的内窥镜旋钮制动装置100。旋钮装置300包括壳体200、第一拉线轮310、第二拉线轮320、第一旋钮410及第二旋钮420。第一拉线轮310伸出壳体200外与第一旋钮410连接。第二拉线轮320贯穿第一拉线轮310伸出壳体200外，并与第二旋钮420连接。一个内窥镜旋钮制动装置100用于对第一旋钮410制动，另一个内窥镜旋钮制动装置100用于对第二旋钮420制动。
上述的内窥镜手柄，采用以上的内窥镜旋钮制动装置100，将制动件120一一对应滑动设于滑槽112内，并保证制动件120穿过滑槽112伸出固定架110外。当套在固定架110外的制动钮130旋转至预设角度时，其内壁上的推动部133会与制动件120接触、并推动制动件120在滑槽112内移动。由于滑槽112与工作腔111连通，因此，各个制动件120在推动部133的推动下分别朝工作腔111内伸入，并最终抱紧在旋钮装置300上，以实现旋钮装置300的制动。 如此，通过制动件120与制动钮130之间的配合结构，在制动过程中直接驱使制动件120在滑槽112内移动，便可实现旋钮装置300的制动，其结构设计巧妙、简洁，制动力传递直接、有效，保证旋钮制动效果更佳。同时，在装配时只需将制动件120滑动设于滑槽112内，这样有效简化装配工序，有利于提高装配效率。
进一步地，旋钮装置300还包括第一拉线轮支架510和第二拉线轮支架520。第一拉线轮支架510套设于第二拉线轮320上，并盖设于第一拉线轮310上。第二拉线轮支架520盖设于第二拉线轮320上，并贯穿第二拉线轮320伸出壳体200外。
在一个实施例中，请参考图9，一种内窥镜，其特征在于，包括以上实施例中的内窥镜手柄。
上述的内窥镜，采用以上的内窥镜手柄，将制动件120一一对应滑动设于滑槽112内，并保证制动件120穿过滑槽112伸出固定架110外。当套在固定架110外的制动钮130旋转至预设角度时，其内壁上的推动部133会与制动件120接触、并推动制动件120在滑槽112内移动。由于滑槽112与工作腔111连通，因此，各个制动件120在推动部133的推动下分别朝工作腔111内伸入，并最终抱紧在旋钮装置300上，以实现旋钮装置300的制动。如此，通过制动件120与制动钮130之间的配合结构，在制动过程中直接驱使制动件120在滑槽112内移动，便可实现旋钮装置300的制动，其结构设计巧妙、简洁，制动力传递直接、有效，保证旋钮制动效果更佳。同时，在装配时只需将制动件120滑动设于滑槽112内，这样有效简化装配工序，有利于提高装配效率。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技 术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”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，仅是为了便于描述本发明和简化描述，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发明的限制。
此外，术语“第一”、“第二”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”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本发明中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；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或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
需要说明的是，当元件被称为“固定于”或“设置于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“上”、“下”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
