技术领域technical field

本发明涉及医疗器械领域，特别涉及一种用于新生儿腹腔镜手术中的腹腔内支撑装置。The invention relates to the field of medical instruments, in particular to an intra-abdominal support device used in neonatal laparoscopic surgery.

背景技术Background technique

随着电视技术及摄像技术的发展，以腹腔镜手术为代表的微创手术方法，在最近几年迅速发展。微创治疗技术以其小手术、小创伤为特征而逐步得到广大医生的认可，是未来手术方法发展的一个必然趋势。目前，在妇科、普外科等涉及腹腔内的手术，正逐步由开放性手术而转变为腔内微创手术。越来越多的医生通过腹腔镜技术培训，手术操作越来越娴熟，在各级医院的推广普及中发挥了重要的作用，另一方面也进一步推动了腹腔镜及配套手术器械的发展。With the development of television technology and camera technology, minimally invasive surgical methods represented by laparoscopic surgery have developed rapidly in recent years. Minimally invasive treatment technology is gradually recognized by doctors because of its small operation and small trauma. It is an inevitable trend in the development of future surgical methods. At present, in gynecology, general surgery and other operations involving the abdominal cavity, it is gradually changing from open surgery to minimally invasive surgery in the cavity. More and more doctors have been trained in laparoscopic technology, and their surgical operations are becoming more and more proficient, which has played an important role in the promotion and popularization of hospitals at all levels. On the other hand, it has further promoted the development of laparoscopy and supporting surgical instruments.

目前微创手术已经成为小儿外科及新生儿外科手术的主流方式，由于新生儿的独特性，腹腔较小，当建立气腹后，腹腔内压力不能过高，否则将会影响呼吸，出现循环不稳等情况，而腹腔内气压不足导致手术操作空间过小，影响正常手术，延长手术时间，现有技术中，公开号为CN104983452B的中国专利文献中提出了变径腹腔穿刺器的制造方法及变径腹腔穿刺器，实现了多种规格的手术器械可在同一个穿刺套管中使用，但是并不能对新生儿的腹腔操作空间进行扩大，因此，本申请提供了一种用于新生儿腹腔镜手术中的腹腔内支撑装置来满足新生儿的腹腔镜手术需求。At present, minimally invasive surgery has become the mainstream method of pediatric surgery and neonatal surgery. Due to the uniqueness of newborns, the abdominal cavity is small. stable situation, and insufficient intra-abdominal air pressure leads to too small operation space, which affects normal operation and prolongs operation time. Diameter abdominal puncture device realizes that various specifications of surgical instruments can be used in the same puncture sleeve, but it cannot expand the abdominal operation space of newborns. Therefore, the application provides a newborn laparoscopic Intra-abdominal support device during surgery to meet the needs of laparoscopic surgery for newborns.

本发明与现有技术相比，至少具有如下有益效果：Compared with the prior art, the present invention has at least the following beneficial effects:

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 scheme, 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. The hand turns the threaded sleeve through the hand wheel to make it move downward along the puncture tube, and the inner ring of the lower bearing moves down accordingly, and synchronously drives the lower sliding cylinder through the outer ring of the lower bearing and multiple vertical connecting rods. Under the guidance of a vertical guide groove, it moves downward, thereby prompting multiple sets of first connecting rods and second connecting rods to expand outward synchronously with an umbrella-like internal structure. In this way, it can make up for the disadvantage of insufficient air pressure in the abdominal cavity after the establishment of pneumoperitoneum, expand the surgical operation space in 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, when the medical staff turns the handwheel to drive the threaded sleeve to spiral downward, it can ensure that the position of the puncture tube is kept fixed, which acts as a limiter and prevents the axis position of the puncture tube from changing, causing the expansion air bag to be in place. Unexpected displacement occurs in the abdominal cavity, which improves the stability during the operation. At the same time, by setting the auxiliary air bag connected with the expansion air bag, the contact area of the air bag in the abdominal cavity is increased, and the stability of the abdominal support is further improved. In this method, the surgical instrument penetrates the puncture tube into the abdominal cavity and the operable space is relatively fixed, which optimizes the practicability 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 into the abdominal cavity of the newborn through the abdominal puncture device, one end of the puncture tube is passed through the inner tube and extended to the abdominal cavity, and then the medical staff hold the top of the puncture tube with one hand, The other hand turns the threaded sleeve through the handwheel to make it move downwards along the puncture tube, the inner ring of the lower bearing moves down accordingly, and synchronously drives the lower slide cylinder 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 expand outward synchronously with an umbrella-like internal structure, and at the same time, gas is input into the expansion air bag through the connecting tube, The expansion air bag is expanded inside the neonatal abdominal cavity. In this way, the disadvantage of insufficient air pressure in the abdominal cavity after the establishment of pneumoperitoneum can be compensated, the operating space in the abdominal cavity can be expanded, the operation time can be shortened, and the safety during the operation can be improved.

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, when the medical staff turns the handwheel to drive the threaded sleeve to spiral downward, it can ensure that the position of the puncture tube is kept fixed, which acts as a limiter and prevents the axis position of the puncture tube from changing, causing the expansion air bag to be in place. Unexpected displacement occurs in the abdominal cavity, which improves the stability during the operation. At the same time, by setting the auxiliary air bag connected with the expansion air bag, the contact area of the air bag in the abdominal cavity is increased, and the stability of the abdominal support is further improved. In this method, the surgical instrument penetrates the puncture tube into the abdominal cavity and the operable space is relatively fixed, which optimizes the practicability of the support device.
