Translated fromChineseDescription
Translated fromChinese技术领域technical field
本发明涉及内窥镜领域，具体而言涉及一种腔镜手术组件。The invention relates to the field of endoscopes, in particular to a laparoscopic surgery component.
背景技术Background technique
传统腹腔镜手术需要在腹部用穿刺器建立多个通道，分别放置用于观察的腹腔镜和多种手术器械，多采用3-5孔。传统内窥镜只有一颗镜头，无法直观显示距离，且宫腔镜硬镜依赖镜头本身的视场角度大小，无法偏摆观察，存在观察死角。Traditional laparoscopic surgery needs to establish multiple channels in the abdomen with a puncture device, and respectively place laparoscopes for observation and various surgical instruments, usually using 3-5 holes. The traditional endoscope has only one lens, which cannot visually display the distance, and the rigid hysteroscope depends on the field of view angle of the lens itself, so it cannot be observed deflected, and there is a dead angle for observation.
中国专利申请CN113509222A公开了一种带全息影像功能的腔镜手术器械，多个摄像头可以提供全息效果，摄像头可以在进出时折叠，既是手术器械又承担了内窥镜的作用，减少了病人腹部开孔的通道数量，降低了病患受到伤害的程度。Chinese patent application CN113509222A discloses a laparoscopic surgical instrument with holographic imaging function. Multiple cameras can provide holographic effects, and the cameras can be folded when entering and exiting. The number of channels in the hole reduces the degree of injury to the patient.
但该发明的腔镜手术器械在进出穿刺通道时无法观察，有一定风险性，且头端器械进行治疗操作时需要考虑避让摄像头干涉到组织，在狭窄空间及特定角度内使用受限。器械在轴向可以旋转，但不可偏摆，旋转时需要双手操作不够直观和便捷。摄像头和器身为一体设计，限制了使用器械的种类，或是需要医院采购多种带摄像头器械，增加了医疗成本。且镜头折叠时不可以避免的带出病灶组织，虽有灭菌措施，但相较传统器械仍有更高交叉感染风险。However, the laparoscopic surgical instrument of this invention cannot be observed when entering and exiting the puncture channel, which has certain risks. In addition, it is necessary to consider avoiding the camera from interfering with the tissue when the head-end instrument is used for treatment operations, and its use is limited in narrow spaces and specific angles. The instrument can be rotated in the axial direction, but it cannot be deflected. It is not intuitive and convenient to operate with both hands when rotating. The integrated design of the camera and the device body limits the types of devices used, or requires the hospital to purchase a variety of devices with cameras, which increases medical costs. Moreover, when the lens is folded, it is inevitable to bring out the lesion tissue. Although there are sterilization measures, there is still a higher risk of cross-infection compared with traditional instruments.
需要一种改进的腔镜手术器械。There is a need for an improved laparoscopic surgical instrument.

Fig. 1a schematically shows the overall assembly structure diagram of the endoscopic surgery assembly according to the present invention, and Fig. 1b schematically shows a partial exploded structure view of the endoscopic surgery assembly according to the present invention.
如图1a和1b所示，根据本发明实施例的腔镜手术组件主要包括.器械部1、.蛇骨连接部2和手柄3。As shown in FIGS. 1a and 1b , the endoscopic surgery assembly according to the embodiment of the present invention mainly includes an
器械部1包括设置在器械部前端的施术器械和与施术器械连接的连接杆，并可滑动地容纳在蛇骨连接部2的内腔中。The
器械部1包括前端的施术器械，用于在人体腔室内执行例如手术操作。根据器械部1的前端的施术器械类型不同，器械部1和蛇骨连接部2可以构成不同组件。施术器械例如包括但不限于剪刀、活检钳、异物钳、锯齿钳。The
根据本发明的一个实施例，器械部1可以包括对应于器械部的钳头1-1，对应于连接杆的拉杆1-3，以及将钳头1-1连接到拉杆1-3的连杆1-2，和设置在拉杆1-3近端用于连接定位的凸台1-4。According to one embodiment of the present invention, the

When the pull rod 1-3 moves to the far end and extends out of the inner cavity of the snake bone joint, the two arms of the connecting rod 1-2 are pushed to expand, thereby driving the pliers head 1-1 to open.
拉杆1-3上设置有弧形凸台1-3-1、导向槽1-3-2。拉杆1-3为半硬材料。如图2所示。The pull rod 1-3 is provided with an arc-shaped boss 1-3-1 and a guide groove 1-3-2. Pull rod 1-3 is semi-hard material. as shown in picture 2.
蛇骨连接部2优选为圆筒形，适于沿着穿刺通道插入人体腔室内。蛇骨连接部2具有设置在远端的的第一摄像头和设置在中部的第二摄像头。The snake-bone connecting part 2 is preferably cylindrical and is suitable for being inserted into a human body cavity along a puncture channel. The snake bone connecting part 2 has a first camera arranged at the far end and a second camera arranged at the middle.
如图3所示，在此实施例中，蛇骨连接部2可以包括蛇骨2-1、摄像头模组2-2和蛇骨线2-3。蛇骨连接部2还可以包括弹簧2-4。As shown in FIG. 3 , in this embodiment, the snake-bone connection part 2 may include a snake-bone 2-1, a camera module 2-2 and a snake-bone wire 2-3. The snake-bone connection part 2 may also include springs 2-4.
蛇骨2-1可以包括第一蛇骨2-1-1、第二蛇骨2-1-2、蛇骨头端2-1-3和蛇骨尾端2-1-4，其中第二蛇骨上切了供第二摄像头2-2-2打开时顶出的槽。在其他实施例中，蛇骨的数量不限于此，可以根据实际需要设置不同数量的蛇骨；供第二摄像头2-2-2打开时顶出的槽也可以设置在其他蛇骨上。The snake bone 2-1 can comprise the first snake bone 2-1-1, the second snake bone 2-1-2, the snake bone end 2-1-3 and the snake bone tail end 2-1-4, wherein the second snake bone Slots are cut in the bone for ejection of the second camera 2-2-2 when opened. In other embodiments, the number of snake bones is not limited thereto, and different numbers of snake bones can be set according to actual needs; the grooves for the second camera 2-2-2 to be ejected when opened can also be set on other snake bones.
摄像头模组2-2可以包括第一摄像头2-2-1、第二摄像头2-2-2和连接线2-2-3。连接线2-2-3将第一摄像头和第二摄像头连接起来便于定位，图3所示的连接线2-2-3是一个示例，其他形式的连接也是可以的。The camera module 2-2 may include a first camera 2-2-1, a second camera 2-2-2 and a connection line 2-2-3. The connection line 2-2-3 connects the first camera and the second camera for easy positioning. The connection line 2-2-3 shown in FIG. 3 is an example, and other forms of connection are also possible.
蛇骨线2-3包括蛇骨线焊接点2-3-1和蛇骨线凸台2-3-2。The snake bone line 2-3 includes the snake bone line welding point 2-3-1 and the snake bone line boss 2-3-2.
进一步的，蛇骨尾端2-1-4上包括连接槽2-1-4-1、卡口2-1-4-2、蛇骨线盲孔2-1-4-3、连接线过孔2-1-4-4和蛇骨头端铆接孔2-1-3-1，见图4。Further, the snake bone tail end 2-1-4 includes a connection groove 2-1-4-1, a bayonet socket 2-1-4-2, a snake bone wire blind hole 2-1-4-3, a connecting wire through Hole 2-1-4-4 and snake head riveting hole 2-1-3-1 are shown in Fig. 4.
弹簧2-4置于蛇骨尾端2-1-4内，用于蛇骨线凸台2-3-2的限位。Spring 2-4 is placed in snake bone tail end 2-1-4, and is used for the limit of snake bone line boss 2-3-2.
图5、图6示出了蛇骨连接部2的各部分的组装示意图。。5 and 6 show schematic diagrams of assembly of various parts of the snake-bone connection part 2 . .
蛇骨线2-3的一端2-3-1焊接于蛇骨头端2-1-3，另一端蛇骨线凸台2-3-2与弹簧2-4在连接槽2-1-4-1中相抵。蛇骨线2-3的中间部分穿过各个蛇骨上的定位特征，例如定位孔，并可以通过焊接或其他方式进行固定，以将蛇骨连接部2的各个部分组装起来。One end 2-3-1 of the snake bone line 2-3 is welded to the snake bone end 2-1-3, and the other end snake bone line boss 2-3-2 and the spring 2-4 are in the connecting groove 2-1-4- 1 in offset. The middle part of the snake wire 2-3 passes through the positioning features on each snake, such as positioning holes, and can be fixed by welding or other methods to assemble the various parts of the snake connecting part 2.
所述第二蛇骨2-1-2包括内凹弧槽面2-1-2-1、外突弧面2-1-2-3和摄像头切割面2-1-2-2。摄像头切割面2-1-2-2例如为三边切割，形成可以被顶起的膜片。蛇骨的材料具有弹性，因此摄像头切割面2-1-2-2顶起后具有一定回弹性，撤销顶出力后会恢复初始位置。The second snake bone 2-1-2 includes an inner concave arc groove surface 2-1-2-1, an outer convex arc surface 2-1-2-3 and a camera cutting surface 2-1-2-2. The cutting surface 2-1-2-2 of the camera is, for example, cut on three sides, forming a diaphragm that can be lifted. The material of the snake bone is elastic, so the cutting surface 2-1-2-2 of the camera has a certain degree of resilience after jacking up, and will return to the original position after canceling the jacking force.
具体而言，将第二蛇骨2-1-2上一个完整的弧面，切割出冂字形的痕迹，保留一侧不切割，这样的切割方式可以使得摄像头被顶出时蛇骨切割面随之变形打开让摄像头出现在蛇骨外面。同时由于还有一个边没被切割，且由于应力的存在，当摄像头不再受到顶出力作用时，蛇骨被切割出的部分就会在回弹力作用下回到初始位置，同时将摄像头压回到蛇骨管内部，恢复到摄像头被顶出前的位置。Specifically, a complete curved surface on the second snake bone 2-1-2 is cut into a zigzag trace, and one side is left uncut. This cutting method can make the snake bone cutting surface follow the camera when the camera is pushed out. The deformation is turned on so that the camera appears outside the snake bone. At the same time, because there is still a side that has not been cut, and due to the existence of stress, when the camera is no longer subjected to the ejection force, the cut part of the snake bone will return to the original position under the action of the rebound force, and the camera will be pressed back at the same time. Go inside the snake bone tube and restore to the position before the camera was ejected.
第一蛇骨2-1-1结构除了没有摄像头切割面2-1-2-2外，其他结构与第二蛇骨2-1-2一致，见图6。The structure of the first snake bone 2-1-1 is the same as that of the second snake bone 2-1-2 except that there is no camera cutting surface 2-1-2-2, as shown in FIG. 6 .
蛇骨头端和蛇骨尾端与各个蛇骨相邻的部分也可以形成对应的内凹弧槽面和外突弧面。The parts adjacent to the snake bones at the end of the snake bone and the tail end of the snake bone can also form corresponding concave arc groove surfaces and outwardly protruding arc surfaces.
蛇骨连接部2的各蛇骨、蛇骨头端和蛇骨尾端之间相邻的内凹弧槽面与外突弧面相配合，使得蛇骨节直接可以发生相对转动，从而整个蛇骨连接部2可以一定范围内任意角度摆动，见图7。The adjacent concave arc groove surfaces between the snake bones, the snake head end and the snake bone tail end of the snake bone joint 2 cooperate with the outwardly protruding arc surface, so that the snake joints can directly rotate relative to each other, so that the entire snake bone joint 2 can swing at any angle within a certain range, see Figure 7.
在组装状态下，所述连接线2-2-3通过连接线过孔2-1-4-4穿过蛇骨尾端2-1-4，使得第二摄像头2-2-2放置在摄像头切割面2-1-2-2相对应的位置，见图8。组装到位后，所述连接线2-2-3可以相对于蛇骨尾端2-1-4固定，以使得摄像头在蛇骨连接部2中的位置相对固定。In the assembled state, the connecting wire 2-2-3 passes through the connecting wire via hole 2-1-4-4 through the tail end 2-1-4 of the snake bone, so that the second camera 2-2-2 is placed on the camera See Figure 8 for the position corresponding to the cutting surface 2-1-2-2. After being assembled in place, the connection wire 2-2-3 can be fixed relative to the tail end 2-1-4 of the snake bone, so that the position of the camera in the snake bone connection part 2 is relatively fixed.
当拉杆1-3向前运动时，弧形凸台1-3-1将第二摄像头2-2-2向外顶起，同时摄像头切割面2-1-2-2被第二摄像头2-2-2顶起，第二摄像头2-2-2伸出蛇骨连接部。当拉杆1-3向后运动时，弧形凸台1-3-1不再对第二摄像头2-2-2起到支撑作用，第二摄像头2-2-2在摄像头切割面2-1-2-2的作用力下回到蛇骨连接部内部。When the pull rod 1-3 moves forward, the arc-shaped boss 1-3-1 pushes the second camera 2-2-2 outward, and at the same time, the cutting surface 2-1-2-2 of the camera is captured by the second camera 2-2-2. 2-2 lifts up, and the second camera 2-2-2 protrudes from the connecting part of the snake bone. When the pull bar 1-3 moves backward, the arc-shaped boss 1-3-1 no longer plays a supporting role for the second camera 2-2-2, and the second camera 2-2-2 is on the camera cutting surface 2-1. Return to the inside of the snake bone joint under the force of -2-2.
弧形凸台1-3-1形成有弧形面，以将第二摄像头2-2-2平稳地顶出去。弧形凸台1-3-1突出拉杆1-3的高度进行适当设置，以使得第二摄像头2-2-2能够顶出蛇骨连接部2的内腔到适当的高度，形成适当的视角。The arc-shaped boss 1-3-1 is formed with an arc-shaped surface to push out the second camera 2-2-2 smoothly. The height of the arc-shaped boss 1-3-1 protruding from the tie rod 1-3 is properly set so that the second camera 2-2-2 can push out of the inner cavity of the snake bone connection part 2 to an appropriate height to form an appropriate viewing angle .
拉杆1-3形成有导向槽1-3-2，如图2所示。导向槽1-3-2例如可以由沿着弧形凸台1-3-1两侧设置的侧壁构成，使得无论拉杆1-3前进或后退第二摄像头2-2-2始终在导向槽1-3-2内运动，如图9所示。第二摄像头2-2-2始终在导向槽1-3-2内运动可以确保第二摄像头2-2-2的周向位置基本固定，从而能够顺利地从摄像头切割面2-1-2-2处顶出去。弧形凸台1-3-1位于导向槽1-3-2的中间位置。The pull rod 1-3 is formed with a guide groove 1-3-2, as shown in FIG. 2 .
