Definitions
- the invention relates to an endoscopic surgical instrument, in particular to a device and a system for direct-viewing abortion and curettage in endoscopic surgery.
- Abortion surgery refers to the use of surgical methods to terminate pregnancy.
- Abortion surgery methods usually include negative pressure suction and forceps curettage.
- the embryo tissue in the uterus is sucked out with a straw or the embryo tissue in the uterus is taken out with surgical instruments such as oval forceps to achieve the purpose of terminating pregnancy. Therefore, the core of abortion surgery lies in two aspects: one is that the embryonic tissue needs to be removed to prevent incomplete abortion; the other is to prevent accidental damage to the uterus during the operation, such as accidental perforation of the uterus.
- abortion surgery requires operations in the uterus, traditional abortion surgery often relies on the experience and feeling of the doctor, so various complications are prone to occur.
- laparoscopic technology With the development of laparoscopic technology, more and more operations are completed under laparoscopic surgery, and abortion operations are gradually being performed under laparoscopic direct vision.
- the lens module is placed at the forefront of the direct-view flow device. After the embryo implantation tissue is found through the camera lens, the negative pressure suction port at the back of the camera is used to attract the implanted embryo tissue. The implantation embryo is peeled off through repeated insertion and insertion of the artificial flow tube. Because the camera is located at the forefront, the specific process of the embryo peeling from the implantation position is still invisible during the clinical operation of the prior art direct-view artificial flow device. There is a risk of incomplete abortion clinically.
- the lens module itself has a certain height and the distance between the suction port and the suction port is at least 8mm, it is difficult for the prior art direct-view flow device for implanted embryos near the entrance of the fallopian tube, that is, near the fundus of the uterus. Remove, and if the insertion depth of the flow tube is too large, it is easy to cause accidental damage to the uterine fundus, and even cause serious consequences of uterine perforation.
- the direct-viewing flow curettage device and system of the present invention through the observing system, especially the rear observing system design, puts the curettage mechanism in front, so as to ensure that there is no dead corner in the embryo removal process and avoid the incomplete flow. Moreover, the design of the rear-mounted observation system can ensure that the whole process of the observation operation can be in the observation field, thereby effectively avoiding accidental injury to the uterus.
- the clinical use process of the direct vision abortion and curettage device and system of the present invention is safer and more effective.

It can be clearly observed whether the embryonic tissue is completely removed during the operation, and whether the uterus is accidentally injured during the operation can be observed.
- the clinical use process is very safe and reliable.
- the curettage mechanism 1 and the negative pressure suction mechanism 4 can be designed as relatively independent mechanisms, so that while ensuring the curettage effect of the curettage mechanism 1 on implantation embryos, it can also pass through the implantation mechanism very effectively.

Description
本发明涉及一种腔镜手术器械,特别是用于腔镜手术中直视人流***装置及***。
人流手术是指用手术的方法终止妊娠。人流手术方式通常包括负压吸引术和钳刮术等方式,用吸管将子宫内的胚胎组织吸出或用卵圆钳等手术器械将子宫内的胚胎组织取出,达到终止妊娠的目的。因此,人流手术的核心在于两个方面:一是胚胎组织需要清除干净,防止人流不全;二是防止手术过程中对子宫造成意外伤害,如造成子宫意外穿孔等。
由于人流手术需要在子宫内进行操作,传统的人流手术经常依靠于医生的经验和感觉,因此容易出现各种并发症。随着腔镜技术的发展,越来越多的手术在腔镜手术下完成,其中人流手术也开始逐步在腔镜直视下进行。
现有技术的直视人流装置,镜头模组置于直视人流装置的最前端,是通过摄像镜头发现胚胎着床组织后,用位于摄像头后端的负压吸引口吸引着床的胚胎组织,然后通过人流管的反复抽插来完成着床胚胎的剥离,因摄像头位于最前端,所以,现有技术的直视人流装置的临床操作时,胚胎从着床位剥离的具体过程仍然是不可视的,临床上存在人流不全的风险。此外,由于镜头模组本身有一定高度,至负压吸引口之间有至少8mm的距离,因此,对于输卵管入口附近,即子宫底附近的着床胚胎,现有技术的直视人流装置很难进行清除,而且如果人流管的抽插深度过大时,容易对子宫底造成意外损伤,甚至造成子宫穿孔的严重后果。
因此,需要对现有的直视人流装置进行进一步改进,以保证胚胎从着床位的分离过程全程可视,避免人流不全的风险,同时更好地避免对子宫造成意外伤害,提高人流过程的精准性和效率。

参考图2-2和图2-3,本实施例中,所述刮杯11-2的前端是设有通孔11-22的刮台 11-23,临床手术中,尤其是当胚胎组织的着床位位于子宫底时,只要旋转所述刮杯11-2,所述刮台11-23也随之发生旋转,即可将胚胎组织从子宫底上刮除,临床使用中可以适应各种不同的胚胎着床位置。
所述刮杯11-2采用透明医用材料制造。透明的材质,可以保证所述刮杯11-2不会阻挡所述摄像头22-1的观察路径,从而保证所述刮杯11-2前端的组织也能被所述观察机构2观察到,保证手术过程的全程、全区域观察。
本实施例中,由于所述诊刮器11采用的是所述刮杯11-2,所述刮杯11-2的底部可以形成刮台11-23,所述刮台11-23因为位于所述直视人流***装置100的最前端,因此,所述刮台11-23可以贴合着子宫进行胚胎组织的刮除,即使是子宫底的着床位也可以很方便地将胚胎组织完全清除。
实施例3:带刮网的本发明之直视人流***装置
参考图3至图3-4,本实施例与实施例1的区别在于,本实施例中,本实施例中,所述诊刮器11是刮网11-3。
本实施例中,所述***机构1的诊刮器11是刮网11-3。所述摄像头22-1可以直接从网状空隙中观察所述刮网11-3后面的情况,即使所述刮网11-3不是透明材料制成也可以实现手术过程的全程观察和手术区域的全景观察。
参考图3,本实施例中,所述***机构1的诊刮器11的刮网11-3能压缩在所述外鞘管5-0内,当向后撤除所述外鞘管5-0的约束后,所述刮网11-3能完全恢复或基本恢复压缩前的形状。
参考图3-1,所述刮网11-3至少含一个诊刮丝11-31。本实施例中,所述刮网11-3是由2根诊刮丝11-31缠绕组合而成,呈十字形状,且在顶端由所述诊刮丝11-31缠绕呈环形平台。这种十字形的结构设计,只要轻微旋转所述
实际应用中,所述刮网11-3可以是1根所述诊刮丝11-31缠绕而成也可以是多跟所述诊刮丝11-31缠绕后叠加组合而成,而且所述刮网11-3可以制造成任何形状,申请人在此不一一举例说明,但都不脱离本申请的保护范围。
所述***机构1的诊刮器11还可以是丝材制造的编织网。柔软的编织网设计,着床胚胎刮除过程中施加的力更加轻柔、均匀,对子宫是伤害更小。
所述刮网11-3采用医用弹性材料制造。所述刮网11-3可以在保证刮除效果的同时,向前运动的过程中,医用弹性材料的弹性作用可以起到很好的缓冲作用,使得所述刮网11-3不会由于运动速度过快而对子宫造成意外伤害。
所述刮网11-3采用医用弹性不锈钢或医用钛镍形状记忆合金制造。申请人在此只列举 了上述两种医用金属弹性材料,实际应用中,本领域的技术人员还可以根据需要选取不同的医用弹性材料制造,都并不脱离本申请的保护范围。
所述刮网11-3采用医用透明弹性医用高分子材料制造。所述刮网11-3还可以采用医用透明的弹性医用高分子材料制造,在保证弹性缓冲的同时,可以完全不遮挡所述摄像头22-1的观察路径,观察效果更好。
为保证所述直视人流***装置100的临床使用的安全性,所述直视人流***装置100采取一次性使用设计。一次性使用的实现可以通过控制程序设计,如设定使用时间等,来实现,也可以通过结构设计来实现。参考图3-5,例如,可以在所述直视人流***装置100的外侧设有可撕裂的外套5-4,所述直视人流***装置100进入子宫后,需要撕开所述外套5-4,释放所述刮网11-3,手术完毕后,将所述直视人流***装置100撤出体外时,由于所述刮网11-3已经释放,因此无法再次进入体内重复使用,从而实现所述直视人流***装置100的一次性使用。
本实施例中,由于所述刮网11-3采用了弹性材料制成,所述刮网11-3可以在保证刮除效果的同时,向前运动的过程中,医用弹性材料的弹性作用可以起到很好的缓冲作用,使得所述刮网11-3不会由于运动速度过快而对子宫造成意外伤害,使用过程更加安全。
实施例4:本发明之直视人流******
参考图4-1,本实施例之直视人流******含实施例3之直视人流***装置。
本实施例中,所述直视人流******900含所述直视人流***装置100、壳体101、显示***102、图像处理***103、及电源***104;所述显示***102放置在所述壳体101上;所述图像处理***103、及所述电源***104安装所述壳体101内;所述显示***102、所述图像处理***103、及所述电源***104通过所述电路3连接在一起;所述直视人流***装置100的负压吸引机构4的吸引出口42与医院的负压吸引器或医用专用负压源的负压管连接。
临床使用时,将所述吸引出口42与医院的负压吸引器或医用专用负压源的负压管连接,开启所述电源***104,所述直视人流******900开始工作,所述观察机构2启动,所述观察机构2采集的视频信号经所述图像处理***103处理后可经有线或无线的方式传输到所述显示***102并在所述显示***102上进行显示。在所述摄像头22-1的观察下,将所述直视人流***工作100沿***,经宫颈口进入子宫内,找到着床的胚胎组织,然后用所述***机构1的诊刮器11将着床的胚胎组织从子宫上剥离,打开所述负压吸引器或医用专用负压源,剥离的胚胎组织和伴随产生的血水经所述吸引出口42被吸引排出体外,直至胚胎组织被完全剥离并被吸引排出体外即可完成人流手术。
本实施例之直视人流******可以在所述显示***102上直观地显示所述直视人流***装置100进入子宫以及胚胎组织刮除的全过程,手术过程中不会出现人流不全的情况,而且由于是完成直视下进行清除,因此,不会由于手术动作过大而造成子宫底的意外损伤,可以非常好地避免对子宫底造成损伤,不会出现子宫穿孔等严重医疗事故。临床手术过程非常安全、有效。
实施例5:含冲洗***的本发明之直视人流******
参考图4-2,本实施例之直视人流******与实施例4的不同在于,本实施例中,所述直视人流******还含冲洗***106。
本实施例中,所述直视人流******900含所述直视人流***装置100、壳体101、显示***102、图像处理***103、电源***104、及冲洗***106;所述显示***102放置在体101上;所述图像处理***103、所述电源***104、及所述冲洗***106安装所述壳体101内;所述显示***102、所述图像处理***103、所述电源***104、及所述冲洗***106通过所述电路3连接在一起;所述直视人流***装置100的负压吸引机构4的吸引出口42与医院的负压吸引器或医用专用负压源的负压管连接;所述冲洗***106的进水口106-1通过水管106-4与输液瓶或袋7连接,所述冲洗***106的出水口106-2通过水管106-4与所述直视人流***装置100的冲洗机构6的进水口62相连接。
本实施例中,所述冲洗***106采用蠕动泵106-3驱动。所述蠕动泵106-3可以更精确地控制进水的流量和速度。当然实际应用中,本领域的技术人员还可以采取不同的驱动装置来驱动所述冲洗***106,都并不脱离本申请的保护范围。
本实施例之直视人流******由于含有冲洗***106,所述冲洗***106可以在手术过程中及时对所述直视人流***装置100和周边组织进行冲洗,保证观察视野保持清洁的同时可以及时对手术部位进行冲洗,从而及时观察胚胎组织是否已经被完全从着床位被清除,保证人流手术过程胚胎组织的完全,有效避免人流不全的情况发生,临床手术过程更加安全。
实施例6:含负压源的本发明之直视人流******
参考他4-3,本实施例之直视人流******与实施例5的不同在于,本实施例中,所述直视人流******还含负压吸引器105。
本实施例中,所述直视人流******900含所述直视人流***装置100、壳体101、显示***102、图像处理***103、电源***104、负压吸引器105、及冲洗***106;所述显示***102放置在体101上;所述图像处理***103、所述电源***104、所述负压吸引器105、及所述冲洗***106安装所述壳体101内;所述显示***102、所述图像处 理***103、所述电源***104、所述负压吸引器105及所述冲洗***106通过所述电路3连接在一起;所述直视人流***装置100的负压吸引机构4的吸引出口42与所述负压吸引器105连接;所述冲洗***106的进水口106-1通过管道7-1与输液瓶或袋7连接,所述冲洗***106的出水口106-2通过管道7-1与所述冲洗机构6的进水口62相连接。
本实施例中,所述直视人流******900自身含有所述负压吸引器105和冲洗***106,将负压吸引功能和冲洗功能整合到一台设备上,只要一台设备就能完成直视人流的全手术过程,不需要依赖外部负压源和外部冲洗***,大大减少了外部环境对手术过程的限制和影响,适用范围非常广泛。
