Description

一种激光点阵手具及激光点阵治疗设备 技术领域
本发明涉及激光医疗技术领域，尤其涉及一种激光点阵手具及激光点阵治疗设备。
背景技术
激光在医疗美容方面，主要是采用了对人体有益、透过能力较强、人体组织吸收率高的光波波段，利用激光对生物组织选择性光热作用和局灶性光热作用，通过去除衰老萎缩的上皮细胞，增强皮肤胶原蛋白活力，从而增加皮肤弹性，延缓皮肤的衰老，起到养颜美容的效果。
真皮组织在受到一定的刺激后出现新的胶原蛋白组织，对皮肤的刺激可以是带有创伤的气化性治疗方法，也可以是没有明显创伤的非气化型的治疗。带有创伤的气化性治疗方法具有明显的创伤，需要有较长的时间恢复，而且治疗风险较大，非气化性治疗方法虽然风险小，单治疗效果不是很理想。直到点阵激光技术发明，利用局灶性光热作用治疗，从而达到了一定程度满意的疗效，但是安全性却大大提高，缩短了手术时间和术后恢复时间。
点阵激光技术是由点阵激光治疗系统发出的点阵状排列的微小激光光束照射治疗区域，在皮肤和瘢痕上打上微细的小孔，从而在皮肤和瘢痕层形成立体点阵状气化区，继而引起一连串的皮肤和瘢痕反应，刺激皮肤和瘢痕进行自我修复，达到紧肤、嫩肤、去除色斑及改善瘢痕的效果，是介于有创和无创之间的一种微创治疗。其临床优势是效果明确、损伤小、停工期短，深受医患欢迎。
在激光医美行业，激光治疗设备的应用手具，有很多是以使用治疗手柄来实现对患者病患组织的治疗目的，如蜂巢点阵手柄、DOE衍射手柄等。此类手具是将激光器输入的大光斑平行光束，分散并聚焦为多个成点阵状的更细小的微光束。以此来实现更微小的治疗创伤面及更集中的激光能量。临床应用上，需要针对患者具体情况选择不同密度、间距的激光点阵，从而达到最好的资料效果。现有的手具要么点阵密度和点间距离不可调，需要更换不同手具进行调节；要么调节结构复杂，多数通过步进电机改变透镜光路之间的间隔，以改变点阵距离，由于光学镜片对间隔要求较高，从而对电机的控制精度要求较高，同时由于电机的加入，一方面成本较高，另外造成可靠性降低。

具体实施方式
下面结合附图和实施例对本发明作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本发明，而非对本发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明相关的部分而非全部结构。
图1为本发明实施例提供的一种激光点阵手具的立体结构示意图，图2为图1所示激光点阵手具的爆炸示意图，图3为图1所示激光点阵手具中移位结构的示意图，图4为沿图3中AA的剖面结构示意图，参考图1-图4，激光点阵手具包括移位结构02、镜筒03和至少两个微透镜片08。移位结构02位于镜筒03的第一端。移位结构02可以在镜筒03的第一端所在平面内移动。沿镜筒03的延伸方向(即镜筒03的轴线方向)，移位结构02与镜筒03的第二端之间的距离保持不变。其中，镜筒03的第二端与镜筒03的第一端相对。
移位结构02包括至少两个卡槽13。至少两个微透镜片08固定于移位结构02的卡槽13内。一个微透镜片08位于移位结构02的一个卡槽13内，两个微透镜片08分别位于移位结构02的两个卡槽13内。在一实施方式中，卡槽13的数量等于微透镜片08的数量，每一个卡槽13对应安装一个微透镜片08。在另一实施方式中，卡槽13的数量大于微透镜片08的数量，多个微透镜片08分别对应安装于多个卡槽13内，且存在部分卡槽13未安装微透镜片08。
至少两个微透镜片08包括第一微透镜片04和第二微透镜片05。微透镜片 08包括多个微透镜，即，第一微透镜片04和第二微透镜片05均包括多个微透镜。第一微透镜片04中微透镜的数量与第二微透镜片05中微透镜的数量不同。
本发明实施例提供一种激光点阵手具，在镜筒03的第一端设置移位结构02，移位结构02包括至少两个卡槽13，至少两个卡槽13分别用于安装微透镜数量不同的第一微透镜片04和第二微透镜片05。从而，在需要采用第一微透镜片04的场景中，通过移位结构02的移动，带动第一微透镜片04移动至镜筒03的光路中(例如移动至镜筒03的轴线上)；在需要采用第二微透镜片05的场景中，通过移位结构02的移动，带动第二微透镜片05移动至镜筒03的光路中(例如移动至镜筒03的轴线上)。本发明实施例通过移动移位结构02，来切换不同的微透镜片08，实现了操作简单，结构稳定，治疗面积、点阵密度和点间距离都可精确调节的激光点阵手具。
需要说明的是，在已知技术中，采用电机改变成像透镜之间的距离，进而实现点阵数目的变换，成本较高，而且结构复杂。本发明实施例提供一种激光点阵手具，采用微透镜阵列更换的构思，不改变后面的光路设计，从而改变治疗面的点阵数目。本发明实施例提供一种激光点阵手具，可以为铒激光产品点阵扫描产品，用于皮肤美容和治疗。
可选地，参考图1-图4，移位结构02包括可变微透镜旋转盘，卡槽13位于可变微透镜旋转盘上，可变微透镜旋转盘转动连接于镜筒03的第一端。本发明实施例中，移位结构02包括可变微透镜旋转盘，通过转动可变微透镜旋转盘，来切换不同的微透镜片08。
示例性地，参考图1-图4，在需要采用第一微透镜片04的场景中，通过转动可变微透镜旋转盘，带动第一微透镜片04移动至镜筒03的光路中(例如移 动至镜筒03的轴线上)；在需要采用第二微透镜片05的场景中，通过转动可变微透镜旋转盘，带动第二微透镜片05移动至镜筒03的光路中(例如移动至镜筒03的轴线上)。
可选地，参考图1-图4，可变微透镜旋转盘的外侧面设置有直纹滚花14。可变微透镜旋转盘的形状呈圆柱形，可变微透镜旋转盘的侧面为圆柱面，可变微透镜旋转盘的侧面设置有直纹滚花14，用于增加手指与变微透镜旋转盘的摩擦力，方便手指操作。
图5为本发明实施例提供的另一种激光点阵手具的立体结构示意图，图6为图5所示激光点阵手具的爆炸示意图，图7为图5所示激光点阵手具中移位结构的示意图，图8为沿图7中AA的剖面结构示意图，图9为沿图7中BB的剖面结构示意图，参考图5-图9，移位结构02包括平移条，卡槽13位于平移条上，平移条滑动连接于镜筒03的第一端。本发明实施例中，移位结构02包括平移条，通过平移推拉平移条，来切换不同的微透镜片08。
示例性地，参考图5-图9，在需要采用第一微透镜片04的场景中，通过平移推拉平移条，带动第一微透镜片04移动至镜筒03的光路中(例如移动至镜筒03的轴线上)；在需要采用第二微透镜片05的场景中，通过平移推拉平移条，带动第二微透镜片05移动至镜筒03的光路中(例如移动至镜筒03的轴线上)。
可选地，参考图5-图9，平移条沿滑动方向延伸的至少一个端部设置有凹槽16。平移条的形状呈长条状，平移条沿其滑动方向延伸。平移条的至少一个端部设置有凹槽16，用于增加手指与平移条的接触力，方便手指操作。
示例性地，参考图5-图9，平移条的两端分别设置有一个凹槽16，便手指 推拉平移条。
可选地，参考图1-图9，移位结构02的外侧面设置有与卡槽13对应的凹球槽15。每一个卡槽13对应地设置一个凹球槽15。镜筒03的第一端设置有螺纹孔11，以及与螺纹孔11螺纹连接的球头柱塞01。球头柱塞01与凹球槽15卡接限位。在选定所需要的微透镜片08后，将所需要的微透镜片08移动至镜筒03的光路中，与该微透镜片08所在卡槽13对应的凹球槽15与螺纹孔11对接，将球头柱塞01拧入到镜筒03上的螺纹孔11，直至球头柱塞01进入到凹球槽15，实现对凹球槽15的限位，从而实现对所需要的微透镜片08的限位。
示例性地，参考图2和图4，球头柱塞01包括本体部、弹簧和按压部，弹簧的一端与本体部接触，弹簧的另一端与按压部接触。随着球头柱塞01拧入螺纹孔11的深度越来越深，球头柱塞01的弹簧被压缩，将球头柱塞01的按压部与凹球槽15压紧抵接。
示例性地，参考图1-图4，移位结构02包括可变微透镜旋转盘，卡槽13位于可变微透镜旋转盘上，与卡槽13对应的凹球槽15位于可变微透镜旋转盘的外侧面上。转动可变微透镜旋转盘时，切换不同的微透镜片08，对应地，切换与不同的微透镜片08对应的凹球槽15。
示例性地，参考图1-图4，一一对应的卡槽13和凹球槽15所在的直线，穿过可变微透镜旋转盘的中心。
示例性地，参考图5-图9，移位结构02包括平移条，卡槽13位于平移条上，与卡槽13对应的凹球槽15位于平移条的外侧面上。平移推拉平移条时，切换不同的微透镜片08，对应地，切换与不同的微透镜片08对应的凹球槽15。
示例性地，参考图5-图9，一一对应的卡槽13和凹球槽15所在的直线， 与平移条的滑动方向垂直。
可选地，参考图1-图9，镜筒03包括镜筒凸台07，移位结构02包括限位孔，限位孔12套接于镜筒凸台07上。镜筒凸台07限制移位结构02的移动范围，对移位结构02起到限位作用，防止由于操作者误操作，直接将微透镜片08移动到镜筒03外，从而污染微透镜片08的表面，影响整体使用精度。
可选地，参考图1-图9，至少两个微透镜片08还包括第三微透镜片06。第二微透镜片05位于第一微透镜片04与第三微透镜片06之间。第二微透镜片05中微透镜的数量大于第一微透镜片04中微透镜的数量，第三微透镜片06中微透镜的数量大于第二微透镜片05中微透镜的数量。由此，第一微透镜片04、第二微透镜片05和第三微透镜片06依次排列，且第一微透镜片04、第二微透镜片05和第三微透镜片06中的微透镜的数量依次增加，便于实现不同点阵密度或者点阵间距的逐步切换。
图10为本发明实施例提供的第一微透镜片的立体结构示意图，图11为图10所示第一微透镜片的俯视结构示意图，图12为本发明实施例提供的第二微透镜片的立体结构示意图，图13为图12所示第二微透镜片的俯视结构示意图，图14为本发明实施例提供的第三微透镜片的立体结构示意图，图15为图14所示第三微透镜片的俯视结构示意图，参考图10-图15，第一微透镜片04包括两行两列矩阵排布的微透镜，第二微透镜片05包括三行三列矩阵排布的微透镜，第三微透镜片06包括四行四列矩阵排布的微透镜。
在其他实施方式中，微透镜片08中的多个微透镜还可以呈环形阵列，或者其他不规则的阵列排布。
在其他实施方式中，激光点阵手具可以包括多于三个的微透镜片08，其中， 存在至少两个微透镜片08的微透镜的数量不同。
示例性地，在一实施方式中，激光点阵手具中的移位结构02可以通过手动的方式移动(旋转或者平移推拉)。
示例性地，在另一实施方式中，激光点阵手具包括驱动电机，驱动电极用于驱动移位结构02移动(旋转或者平移推拉)。
本发明实施例还提供一种激光点阵治疗设备，图16为本发明实施例提供的一种激光点阵治疗设备的示意图，参考图1-图16，激光点阵治疗设备包括上述实施例中的激光点阵手具21(图16中示意出激光点阵手具21中的微透镜片，未示意出镜筒)，以及沿光轴依次设置的第一透镜组22、X方向扫描振镜23、Y方向扫描振镜24和第二透镜组25。第一透镜组22位于激光点阵手具21与X方向扫描振镜23之间，第二透镜组25位于Y方向扫描振镜24和治疗面之间。其中，治疗面用于接收激光点阵，治疗面例如可以为人体皮肤。微透镜片08将入射光分散为多束点阵状排列的微小激光光束，多束点阵状排列的微小激光光束穿过第一透镜组22后，投射至X方向扫描振镜23和Y方向扫描振镜24，由X方向扫描振镜23沿X方向的振动实现X方向的扫描，由Y方向扫描振镜24沿Y方向的振动实现Y方向的扫描。由Y方向扫描振镜24出射的光线投射至第二透镜组25，穿过第二透镜组25后，投射至治疗面。由于本发明实施例中的激光点阵治疗设备包括上述实施例中的激光点阵手具21，因此，最终到达治疗面的点阵数目可以变换间距，变换点数，在一定范围内实现扫描，从而达到激光治疗的目的。
示例性地，参考图1-图16，第一透镜组22固定于镜筒03第二端设置的卡槽13内，沿镜筒03的延伸方向(即镜筒03的轴线方向)，移位结构02与第 一透镜组22之间的距离保持不变。
注意，上述仅为本发明的较佳实施例及所运用技术原理。本领域技术人员会理解，本发明不限于这里所述的特定实施例，对本领域技术人员来说能够进行各种明显的变化、重新调整、相互结合和替代而不会脱离本发明的保护范围。因此，虽然通过以上实施例对本发明进行了较为详细的说明，但是本发明不仅仅限于以上实施例，在不脱离本发明构思的情况下，还可以包括更多其他等效实施例，而本发明的范围由所附的权利要求范围决定。
