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 termination of pregnancy by surgical methods.
  • Abortion surgery methods usually include negative pressure suction and forceps curettage.
  • the embryonic 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 front end 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 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.

Description

直视人流刮宫装置及系统 技术领域
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刮宫装置及系统。
背景技术
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，申请人在专利申请《直视人流刮宫装置及系统》(申请号：201910612451.3、201921057784.6)中对现有的直视人流装置进行了进一步改进，将摄像头后置于诊刮器，以保证胚胎从着床位的分离过程全程可视，但现有的技术中，都是通过一个摄像头进行拍摄和观察，而每个摄像头的视场角都是有限的，因此，在超出视场的区域，摄像头是无法观察到的，为解决单个摄像头的拍摄区域限制问题，本申请中，申请人对直视人流装置进行了进一步改进。
发明内容
本发明之直视人流刮宫装置及系统，通过多镜头观察系统的设计，尤其是后置或内置于诊刮器内的多镜头观察系统设计，不但可以保证观察手术的全过程都能在观察视野内，而且很好地解决了现有单镜头观察视野有限的问题，有效扩大了手术过程的观察视场。本发明之直视人流刮宫装置及系统临床使用过程更加安全、有效。
本发明之直视人流刮宫装置及系统，其特征在于：所述直视人流刮宫装置100含刮宫机构1、观察机构2、电路3、负压吸引机构4、及操作杆5；
A、所述刮宫机构1上含至少1个诊刮器11，所述诊刮器11设在所述操作杆5的前端，而且在所述观察机构2的视野内；
B、所述观察机构2含照明模块21、镜头模组22及信号处理模块23；所述镜头模组22至少含2个摄像头22-1；在所述照明模块21的光场内所述摄像头22-1所观察到的图像和视频经过所述信号处理模块23处理后，由所述电路3输出；
C、所述负压吸引机构4含吸引入口41、吸引出口42及吸引通道43；所述引入口41设在所述操作杆5的前端，所述负压吸引机构4的吸引出口42设在所述操作杆5的后端，所述吸引通道43设在所述操作杆5内；
D、所述操作杆5的后端5-2设有手柄52，所述操作杆5的前端5-1设有刮宫机构1及观察机构2；所述操作杆5的管体5-3内含有所述电路3及负压吸引机构4。
所述诊刮器11设置在所述观察机构2的视野内，临床手术时，可以在所述观察机构2的镜头模组22的作用下，在直视的情况下进行人流手术的全程操作，可以非常清楚地观察到手术过程中胚胎组织是否完全清除干净，而且可以观察到手术过程中是否对子宫造成意外伤害，临床使用过程非常安全、可靠。此外，所述刮宫机构1和所述负压吸引机构4可以设计成相对独立的机构，这样，在保证所述刮宫机构1对着床胚胎的刮除效果的同时，还能够非常有效地通过所述负压吸引机构4将刮除的组织和产生的血水等组织液快速地吸引排出体外。
尤其是所述镜头模组22至少含2个摄像头22-1，很好地解决了现有单镜头观察视野有限的问题，可以有效扩大手术过程的观察视场。尤其是当所述摄像头22-1分别设置于所述操作杆5的前方和侧面时，通过观察视野的叠加，可以对所述操作杆5的周边形成立体观察空间，临床观察效果非常好。
进一步，至少1个所述摄像头22-1设置在所述操作杆5的前端5-1。设置在所述操作杆5的前方的所述摄像头22-1可以很好地对所述操作杆5前方的区域进行观察。
至少1个所述摄像头22-1设置在所述操作杆5的侧面5-5。设置在所述操作杆5的侧 面5-5的所述摄像头22-1可以对所述操作杆5的侧面进行观察。
2个或2个以上所述摄像头22-1的观察区域能够衔接或部分重叠。分别设置在所述操作杆5的前端5-1和侧面5-5的所述摄像头22-1的观察区域相互衔接后可以形成空间观察视场，临床观察效果更好。
进一步，所述摄像头22-1的视场角β不小于90°。优选的，所述视场角β在110°至150°。
所述镜头模组22的摄像头22-1设置在所述诊刮器11的后端，所述诊刮器11位于所述摄像头22-1的视野内。所述摄像头22-1后置的技术方案，可以保证所述诊刮器11完全处于所述摄像头22-1的视野范围内，而且由于所述摄像头22-1的观察角度是面向手术区域前方，因此，在所述过程中不会存在观察盲区，因此，不会产生由于没有及时观察清楚而造成的子宫及附件的意外损伤。同时，由于所述诊刮器11是处于所述摄像头22-1的前方，因此，所述诊刮器11不会由于所述镜头模组22本身的高度产生的遮挡而存在操作死角，胚胎组织在子宫的任何位置着床都能够完全清除，尤其是对于输卵管口附近，即子宫底的着床位，所述诊刮器11也能轻松地对胚胎组织进行清除，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。因此，摄像头后置的技术方案，使得人流的临床手术过程更加安全，更加有效。
所述刮宫机构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。
进一步，所述刮宫机构1的诊刮器11的刮网11-3能压缩在所述外鞘管5-0内；所述刮网11-3从所述外鞘管5-0释放膨胀后可以撑开子宫，扩大观察视野。
所述刮宫机构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。临床使用时，可以将所述刮网11-3收拢至所述外鞘管5-0内，经宫颈进入子宫后，后退所述外鞘管5-0释放所述刮网11-3，所述刮网11-3展开，即可对胚胎组织进行清除。同时，由于所述刮网11-3展开，可以将所述摄像头22-1前端的子宫撑开，扩大观察视野，临床使用过程中，可以更好地观察到手术部位以及周边组织，临床使用过程的观察效果非常好。所述刮网11-3的刮丝11-31可以是丝材、细管材、片材等各种形状的材料制成。而且所述刮网11-3可以根据子宫形状设置成椭球形、梨形等各种几何形状，以更好地适应子宫的形态，尤其适合于子宫难以清除的角落。
所述镜头模组22的摄像头22-1设置在所述诊刮器11的前端。所述摄像头22-1可以直接观察所述负压吸引机构4的吸引入口41的工作状态，确定被剥离的着床组织被所述负压吸引机构4吸引排出体外。
所述镜头模组22的摄像头22-1设置在所述诊刮器11的内部。尤其是当所述摄像头22-1内置在所述刮网11-3内部时，可以通过空间分布的多个所述摄像头22-1立体地观察到所述诊刮器11的整个周边结构，临床使用非常方便。
所述镜头模组22的摄像头22-1的观察方向可以调整。通过调节所述摄像头22-1的观察方向，可以全方位地观察所述诊刮器11的工作状态和周边的组织状况，尤其是可以快速地发现胚胎的着床位，临床使用中观察效果更全面。
