本发明属于医疗器械领域，涉及一种生殖手术用装置，特别是一种方便操作的自动冲液结构及卵母细胞采集仪。
背景技术
卵母细胞采集仪是针对辅助生殖手术中提取卵母细胞而开发的专用设备。目前，市场上的卵母细胞采集仪大多只具有取卵的功能，而冲液是依靠人工手动通过针管来注射冲液，存在不便操作的问题。
公开号为CN214966446U的实用新型专利，公开了一种用于取卵操作的卵子负压吸引器，其上的冲液机构由步进驱动一体机驱动的蠕动泵及冲洗液试管构成，在所述机壳的侧面上壳体上安装有蠕动泵，蠕动泵的进液端通过管路连接至冲洗液试管，蠕动泵的出液端通过管路与双腔取卵针连接。其虽实现了自动冲液的功能，但是，从临床的使用情况来看，在使用时，还需在蠕动泵上连接分别与冲洗液试管以及双腔取卵针连接的无菌管，导致取卵前的准备工作较有不便。
鉴于此，提出一种方便操作的自动冲液结构及卵母细胞采集仪，能够进一步的方便取卵作业，提高取卵效率。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、完整地描述。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要注意的为，除非另有说明，本申请使用的技术术语或者科学术语应当为本发明所属领域技术人员所理解的通常意义。
一种卵母细胞采集仪，包括采集仪本体，所述的采集仪本体包括采集仪外壳、液晶显示屏1、按键5、工作开关6、脚踏冲液口7、脚踏吸引口8、提拿把手3，所述的采集仪外壳由上下扣装的上盖4及底壳11扣装而成，在上盖的前端设有液晶显示屏，在上盖的上端设有提拿把手，在底壳的前端设有按键，在底壳的侧端设有脚踏冲液口及脚踏吸引口，其创新之处在于：在所述上盖的侧部设有自动冲液结构。
该自动冲液结构包括安装壳2、注射器驱动机构及注射器夹持机构，在上盖的侧部安装有安装壳，所述的安装壳为外侧设置卡装凹槽的结构，在卡装凹槽的外侧设有注射器夹持机构，通过注射器夹持机构与卡装凹槽的配合实现对注射器9的稳定夹持，在安装壳内设置有注射器驱动机构，该注射器驱动机构用于驱动注射器的注射推杆，实现对液体的注射。
所述的注射器驱动机构包括导轨架14、电机24、推柄驱动丝杆17、注射器推柄13、导杆22、推杆12、啮合组件，在所述导轨架内安装有由电机驱动的推柄驱动丝杆，电机通过联轴器23与推柄驱动丝杆连接，电机通过支柱18安装在导轨架上，在推柄驱动丝杆上套装有三角滑块39，在三角滑块的三个端角上均设有过孔，该三角滑块的两个端角的部分设有直线轴承21，并分别穿装在在导轨架内上下安装的导杆22上，在三角滑块的另一个端角上转动连接有推杆，在推杆的端部连接注射器推柄，在三角滑块的侧部设有啮合组件，所述推杆通过其上设置的凸块41控制啮合组件与推柄驱动丝杆的啮合与分离，在导轨架的内壁上远离电机的一端导轨架封头19上安装有极限光耦25。
所述的啮合组件包括啮合块20、压簧16及压板15，所述的啮合块20包括铰装部、啮合部40及压接部38，在铰装部的两端分别设置有啮合部及压接部，所述的铰装部铰装在三角滑块的侧壁上，啮合部的下端面与推柄驱动丝杆上的螺纹相适配，啮合部的上端面通过压簧连接有压板，所述的压板固装在三角滑块上，所述的压接部置于推杆的下方。
所述的注射器夹持机构包括夹板10、弹簧26、挡片27及螺钉28，所述的夹板包括夹持板体及在夹持板体内侧下方设置的伸缩轴，在所述安装壳的中部下方设有伸缩孔，所述夹板的伸缩轴通过弹簧穿装在该伸缩孔内，在伸缩轴的端部通过螺钉安装有抵接弹簧的挡片，在伸缩孔的前端设有限位弹簧的挡檐。
电机通过连轴器带动推柄驱动丝杆转动，推柄驱动丝杆将力传递给啮合组件上的啮合块20，啮合块20带动三角滑块沿导杆做线性移动，三角滑块通过推杆与注射器推柄连接，当三角滑块移动时，注射器推柄也随之移动。此时，注射器推柄推动注射器注液。当三角滑块运动到极限位置时，光耦会检测到信号并把相应的信号发送给系统。需要更换注射器时，可逆时针转动注射器推柄，通过推杆上的压块对啮合块20的压接部施力，从而使啮合部抬起与推柄驱动丝杆分离，此时注射器推柄可以自由沿导杆前后移动。安装注射器时，可向外拉注射器夹板，并顺时针旋转90度，装好注射器后，再将注射器夹板逆时针旋转90度，压板在弹簧力的作用下将注射器压紧。此结构可适用于不同直径的注射器。
所述采集仪本体内的负压储能罐为无极可调蓄能罐，该无极可调蓄能罐包括蓄能罐体30、气嘴29、活塞31、活塞驱动丝杆36、步进电机37、支架32、光耦34、光耦座33及光耦挡板35，在所述蓄能罐体的前端设有气嘴，在蓄能罐体的内部设有活塞，该活塞由置于蓄能罐体后部的步进电机通过活塞驱动丝杆驱动伸缩，在活塞驱动丝杆的后端连接有光耦挡板，该光耦挡板的下部设有光耦座，该光耦座通过螺钉与支架连接，该支架通过螺钉安装在采集仪本体的内部，在所述光耦座的后端设有光耦。
工作时，活塞驱动丝杆会跟随步进电机转动，做向前或向后的运动，活塞驱动丝杆与活塞相连，活塞驱动丝杆带动活塞运动，进而调节蓄能罐容积，调节到位置后，步进电机可自动锁紧电机轴，保持蓄能罐容积。光耦挡板到达光耦位置为零位。
在所述采集仪本体的内部设有中央微处理控制器，在中央微处理控制器的输入端上分别连接有吸引脚踏、负压值设定键盘、冲液脚踏及压力传感器，采集仪本体上的液晶显示屏与中央微处理控制器双向连接，在中央微处理控制器 的输出端上分别连接有自动冲液结构、负压泵、自动调压控制器、电磁阀、无极可调蓄能罐及开关阀。液晶显示屏为5.0寸DC80480F050_3111_0C组态串口屏，电容触摸，分辨率为800*480，采用32位处理器，支持JPEG图片，存储容量为128Mbit，RS232通讯，显示精度可达±5mmHg。中央微处理控制器的型号为STM32F103C8T6；负压泵型号为MB20DC；压力传感器的型号为XGZP6857100KPGPN；电磁阀的型号为3V308NCF，通径大，响应快。工作开关与开关阀连接，其型号为CPV15。
中央微处理控制器控制负压泵产生负压，通过自动调压控制器对产生的压力进行调节，调节后储存在无极可调蓄能罐中，使用者根据需要控制电磁阀输出预期压力。所输出的压力恒定、气流稳定。中央微处理控制器控制自动冲液结构进行注液，自动冲液结构是通过电机的转动带动注射器推柄运动，将固定在安装壳上的注射器中的液体注入到人体。
本发明创新设计出适合卵母细胞提取术中用于冲洗的自动冲液结构，液量精度高，流速稳定，节省了人工，减少蠕动泵注液方式不可缺少的泵管耗材的使用，同时避免了泵管消毒灭菌不便的问题。
无极可调蓄能罐，可按照需要无极调节蓄能罐容量，容量小时更容易建立目标负压，当容量大时所输出的负压更加稳定。
负压泵、自动冲液结构、无极可调蓄能罐、自动调压控制器的系统结构，可提供压力恒定，气流稳定的高精度负压主机系统，整机操作方便，便于临床使用。
本采集仪在开机后，设定使用参数，按下工作开关后，无极可调蓄能罐将自动调节到设定容量，同时负压泵启动，系统压力达到设定值，系统通过自动调压控制器调节压力，将系统负压维持在设定值。手术中需要吸引时，踩吸引脚踏，电磁阀打开，输出负压。手术中需要冲洗时，踩冲液脚踏，系统控制自动冲液结构按照设定液量及流量将卵泡液注入卵泡，对卵泡进行冲洗。
尽管为说明目的公开了本发明的实施例和附图，但是本领域的技术人员可以理解：在不脱离本发明及所附权利要求的精神和范围内，各种替换、变化和修改都是可能的，因此，本发明的范围不局限于实施例和附图所公开的内容。
