背景技术Background technique
随着科学技术和医学水平的迅速发展，目前人们普遍追求微创及快速康复，微创手术已经成为当今外科发展的主要方向。荷包吻合器在食管及胃肠手术中的使用能够有效节省手术时间，避免不必要的副损伤，保证手术质量，其性能的优劣直接影响手术进程，对手术效果起着非常重要的作用。With the rapid development of science, technology and medical level, people are generally pursuing minimally invasive and rapid recovery, and minimally invasive surgery has become the main direction of surgical development today. The use of purse-string staplers in esophageal and gastrointestinal surgeries can effectively save surgical time, avoid unnecessary side injuries, and ensure surgical quality. Its performance directly affects the surgical process and plays a very important role in the surgical results.
然而，目前在临床使用的荷包吻合器，存在着头端体积过大、操作杆太粗、头端无法转换角度等缺点，不适用于微创手术及开放手术狭小空间内的操作。虽然目前已有开放手术用的一次性荷包缝合钳面世，但到目前为止，这些产品和新设计均未能完美地解决以上难题。However, the purse-string staplers currently used clinically have shortcomings such as the head end is too large, the operating rod is too thick, and the head end cannot convert the angle. It is not suitable for operations in minimally invasive surgeries and open surgeries in small spaces. Although disposable purse-string suture forceps for open surgery are currently available, so far, these products and new designs have not been able to perfectly solve the above problems.
