患者在进行结直肠手术时，为了增加对需要切除的结直肠操作的便捷性，通常会使用导管将结直肠进行牵出固定，并且为了保证牵出之后导管的稳定性，通常需要使用对导管的辅助固定装置，例如公开号为CN210205567U的一种胃肠外科用直肠固定牵出辅助装置，其技术方案要点是…通过上下设置的第一导向套筒与所述第二导向套筒，可对肠胃固定的管道进行上下稳定固定，从而避免了管道上下长度过长造成晃动，进而增加了肠胃医疗的稳定性。但是该胃肠外科用直肠固定牵出辅助装置在实际使用过程中依旧存在以下缺点：When patients undergo colorectal surgery, in order to increase the convenience of the operation on the colorectum that needs to be resected, they usually use a catheter to pull out and fix the colorectum, and in order to ensure the stability of the catheter after pulling out, it is usually necessary to use the catheter Auxiliary fixation device, such as a rectal fixation and pull-out auxiliary device for gastrointestinal surgery with the publication number CN210205567U, the main point of its technical solution is... through the first guide sleeve and the second guide sleeve arranged up and down, it can be used for gastrointestinal surgery. The fixed pipeline is stably fixed up and down, so as to avoid the shaking caused by the excessive length of the pipeline up and down, thereby increasing the stability of gastrointestinal medical treatment. However, the rectal fixation and pull-out assisting device for gastrointestinal surgery still has the following disadvantages in actual use:
1.传统的辅助固定装置仅仅适用于矩形结构的手术台，而现有的手术台具有不同形态，并且部分具有圆柱体的栏杆，而传统的辅助固定装置无法适应不同型号的手术台，造成了使用时的局限性，其稳定性也较差；1. The traditional auxiliary fixing device is only suitable for operating tables with a rectangular structure, while the existing operating tables have different shapes, and some of them have cylindrical railings, and the traditional auxiliary fixing devices cannot adapt to different types of operating tables, resulting in Limitations in use and poor stability;
2.传统的辅助固定装置对于导管的限位不够稳定，由于手术过程中会带动结直肠和导管晃动，这就容易造成导管在辅助固定装置上移动，进而影响手术的操作，同时需要调节整个辅助固定装置才可实现导管不同角度的限位，增加了操作的繁琐性。2. The traditional auxiliary fixation device is not stable enough to limit the position of the catheter. Since the colorectum and catheter will shake during the operation, it is easy to cause the catheter to move on the auxiliary fixation device, which will affect the operation of the operation. At the same time, the entire auxiliary fixation device needs to be adjusted. Only the fixing device can realize the limitation of different angles of the catheter, which increases the complexity of the operation.
针对上述问题，急需在原有结直肠固定牵出辅助装置的基础上进行创新设计。In view of the above problems, it is urgent to carry out an innovative design on the basis of the original colorectal fixation and retraction aid.
