上述方案中，通过腹腔穿刺器将内管的底端引导至新生儿腹腔内部，将穿刺管的一端贯穿内管并延伸至腹腔，随即医护人员一只手握住穿刺管的顶端，另一只手通过手轮转动螺纹套，使其沿着穿刺管螺旋向下移动，下轴承的内环跟随下移，并通过下轴承的外环及多个垂直连杆同步驱动下方的滑筒，在第一垂直导槽的导向作用下向下移动，从而促使多组第一连杆和第二连杆以类似雨伞内部结构同步向外扩张，同时，通过连通管向扩张气囊内输入气体，将扩张气囊在新生儿腹腔内部扩张开，这样一来，便能弥补建立气腹后腹腔内部气压不足的弊端，扩大腹腔内部的手术操作空间，缩短手术时长，提高手术过程中的安全性。In the above plan, the bottom end of the inner tube is guided into the abdominal cavity of the newborn through the abdominal puncture device, and one end of the puncture tube is passed through the inner tube and extended to the abdominal cavity. Then the medical staff holds the top of the puncture tube with one hand and uses the other hand to The hand rotates the threaded sleeve through the handwheel, causing it to move spirally downward along the puncture tube. The inner ring of the lower bearing follows and moves downward, and synchronously drives the sliding cylinder below through the outer ring of the lower bearing and multiple vertical connecting rods. It moves downward under the guidance of a vertical guide groove, thereby prompting multiple groups of first connecting rods and second connecting rods to expand outward synchronously in a similar internal structure to an umbrella. At the same time, gas is input into the expansion airbag through the connecting tube to expand the airbag. By expanding inside the newborn's abdominal cavity, it can make up for the shortcomings of insufficient intra-abdominal air pressure after pneumoperitoneum is established, expand the surgical operating space inside the abdominal cavity, shorten the operation time, and improve the safety during the operation.
通过设置相对位置固定的定位盘，使得医护人员在转动手轮驱动螺纹套螺旋向下时，确保穿刺管的位置保持固定，起到限位作用，避免穿刺管的轴线位置变化，引起扩张气囊在腹腔内发生不期望位移，提高了手术过程中的稳定性，同时，通过设置与扩张气囊连通的辅助气囊，提高了气囊在腹腔内的接触面积，进一步提高腹腔支撑的稳定性，使得后续手术过程中，手术器具贯穿穿刺管进入腹腔可操作空间相对固定，优化支撑装置的实用性。By setting a positioning plate with a fixed relative position, the medical staff ensures that the position of the puncture tube remains fixed when they turn the handwheel to drive the threaded sleeve to spiral downward, which serves as a limiter and prevents the axis position of the puncture tube from changing, causing the expansion balloon to expand. Unexpected displacement occurs in the abdominal cavity, which improves the stability during the operation. At the same time, by setting up an auxiliary airbag connected to the expansion airbag, the contact area of the airbag in the abdominal cavity is increased, further improving the stability of the abdominal cavity support, making subsequent surgical procedures easier. , the operable space where surgical instruments penetrate the puncture tube and enter the abdominal cavity is relatively fixed, optimizing the practicality of the support device.

One end penetrates the inner tube 2 and extends to the abdominal cavity. Then the medical staff holds the rubber sleeve 28 at the top of the puncture tube 3 with one hand, and uses the hand wheel 26 to rotate the threaded sleeve 22 with the other hand so that it spirals downward along the puncture tube 3 moves, the inner ring of the lower bearing 27 moves downward, and synchronously drives the sliding tube 6 below through the outer ring of the lower bearing 27 and a plurality of vertical connecting rods 29, and moves downward under the guidance of the first vertical guide groove 5. This causes multiple sets of first connecting rods 11 and second connecting rods 15 to expand outward synchronously with an internal structure similar to that of an umbrella. At the same time, gas is input into the expansion airbag 4 through the communication tube 14 to expand the expansion airbag 4 inside the newborn's abdominal cavity. , in this way, it can make up for the shortcomings of insufficient internal air pressure in the abdominal cavity after establishing pneumoperitoneum, expand the surgical operating space inside the abdominal cavity, shorten the operation time, and improve the safety during the operation.
如图8所示，所述定位套1的顶部开设有多个分布均匀的定位槽18，定位套1的顶端还设有相适配的定位盘19，定位盘19的一侧连接有多个定位凸块20，定位凸块20卡设在对应的定位槽18内，通过设置相对位置固定的定位盘19，使得医护人员在转动手轮26驱动螺纹套22螺旋向下时，确保穿刺管3的位置保持固定，起到限位作用，避免穿刺管3的轴线位置变化，引起扩张气囊4在腹腔内发生不期望位移，提高了手术过程中的稳定性，同时，通过设置与扩张气囊4连通的辅助气囊17，提高了气囊在腹腔内的接触面积，进一步提高腹腔支撑的稳定性，使得后续手术过程中，手术器具贯穿穿刺管3进入腹腔可操作空间相对固定，优化支撑装置的实用性。As shown in Figure 8, the top of the positioning sleeve 1 is provided with a plurality of evenly distributed positioning grooves 18. The top of the positioning sleeve 1 is also provided with a matching positioning plate 19. One side of the positioning plate 19 is connected with a plurality of positioning grooves 18. The positioning bump 20 is stuck in the corresponding positioning groove 18. By setting the positioning plate 19 with a fixed relative position, the medical staff ensures that the puncture tube 3 can be ensured when the medical staff turns the handwheel 26 to drive the thread sleeve 22 to spiral downward. The position remains fixed and plays a limiting role to avoid changes in the axis position of the puncture tube 3 and causing undesirable displacement of the expansion balloon 4 in the abdominal cavity, thereby improving the stability during the operation. At the same time, it is connected to the expansion balloon 4 by setting The auxiliary air bag 17 increases the contact area of the air bag in the abdominal cavity, further improving the stability of the abdominal cavity support, so that during subsequent operations, the surgical instruments penetrate the puncture tube 3 and enter the abdominal cavity operable space to be relatively fixed, optimizing the practicality of the support device.
本发明提供的技术方案，通过腹腔穿刺器将内管的底端引导至新生儿腹腔内部，将穿刺管的一端贯穿内管并延伸至腹腔，随即医护人员一只手握住穿刺管的顶端，另一只手通过手轮转动螺纹套，使其沿着穿刺管螺旋向下移动，下轴承的内环跟随下移，并通过下轴承的外环及多个垂直连杆同步驱动下方的滑筒，在第一垂直导槽的导向作用下向下移动，从而促使多组第一连杆和第二连杆以类似雨伞内部结构同步向外扩张，同时，通过连通管向扩张气囊内输入气体，将扩张气囊在新生儿腹腔内部扩张开，这样一来，便能弥补建立气腹后腹腔内部气压不足的弊端，扩大腹腔内部的手术操作空间，缩短手术时长，提高手术过程中的安全性。In the technical solution provided by the present invention, the bottom end of the inner tube is guided to the inside of the newborn's abdominal cavity through an abdominal puncture device, one end of the puncture tube is penetrated through the inner tube and extended to the abdominal cavity, and then the medical staff holds the top of the puncture tube with one hand. The other hand turns the threaded sleeve through the handwheel so that it moves spirally downward along the puncture tube. The inner ring of the lower bearing follows and moves downward, and synchronously drives the sliding cylinder below through the outer ring of the lower bearing and multiple vertical connecting rods. , moves downward under the guidance of the first vertical guide groove, thereby prompting multiple sets of first connecting rods and second connecting rods to synchronously expand outward in a structure similar to the internal structure of an umbrella. At the same time, gas is input into the expansion airbag through the connecting tube. Expanding the expansion balloon inside the newborn's abdominal cavity can make up for the shortcomings of insufficient intra-abdominal air pressure after pneumoperitoneum is established, expand the surgical operating space inside the abdominal cavity, shorten the operation time, and improve the safety during the operation.
通过设置相对位置固定的定位盘，使得医护人员在转动手轮驱动螺纹套螺旋向下时，确保穿刺管的位置保持固定，起到限位作用，避免穿刺管的轴线位置变化，引起扩张气囊在腹腔内发生不期望位移，提高了手术过程中的稳定性，同时，通过设置与扩张气囊连通的辅助气囊，提高了气囊在腹腔内的接触面积，进一步提高腹腔支撑的稳定性，使得后续手术过程中，手术器具贯穿穿刺管进入腹腔可操作空间相对固定，优化支撑装置的实用性。By setting a positioning plate with a fixed relative position, the medical staff ensures that the position of the puncture tube remains fixed when they turn the handwheel to drive the threaded sleeve to spiral downward, which serves as a limiter and prevents the axis position of the puncture tube from changing, causing the expansion balloon to expand. Unexpected displacement occurs in the abdominal cavity, which improves the stability during the operation. At the same time, by setting up an auxiliary airbag connected to the expansion airbag, the contact area of the airbag in the abdominal cavity is increased, further improving the stability of the abdominal cavity support, making subsequent surgical procedures easier. , the operable space where surgical instruments penetrate the puncture tube and enter the abdominal cavity is relatively fixed, optimizing the practicality of the support device.
