Description
外科用直线型切割吻合器的闭合装置 技术领域 Closure device for surgical linear cutting stapler
本发明涉及一种外科用直线型切割吻合器的闭合装置， 属于医疗器械领域。 The invention relates to a closure device for a surgical linear cutting stapler, belonging to the field of medical instruments.
背景技术 Background technique
目前， 直线型切割吻合器是对消化道等生理组织施行外科手术时经常使用的一种医疗器 械， 但对于胃、 肺和肠道组织进行横断吻合切除时， 使用现有切割吻合器， 存在以下缺点： 手术中闭合压縮组织时， 靠器械预设的剪刀差来实现前后的平衡闭合， 显然对于不同厚度的 胃、 肺、 肠组织， 其对器械的反力是不一样的， 由于器械前端为悬臂设计， 器械刚性较差， 对于较厚的组织， 抵钉座会上翘变形， 使前端吻合高度 H变大， 同时也会左右偏移， 造成吻 合钉成形不良， 无法有效吻合组织， 影响手术质量， 给手术安全带来影响； 另外对于吻合不 同的组织， 由于个体或组织差异， 吻合高度是不同的， 一旦选定器械， 现有技术的闭合高度 无法调整， 这样在临床手术中， 有可能压伤组织， 或吻合高度偏大， 影响手术质量。 经研究 发现这些缺点主要是由于外科用直线型切割吻合器的闭合装置的设计缺陷导致的。 At present, the linear cutting stapler is a medical device that is often used for performing surgical operations on physiological tissues such as the digestive tract. However, when the transverse anastomosis of the stomach, lung, and intestinal tissue is performed, the existing cutting stapler is used, and the following Disadvantages: When closing the compressed tissue during surgery, the balance of the scissors is used to achieve the balance of the front and back. It is obvious that for different thicknesses of stomach, lung and intestine tissue, the reaction force to the instrument is different, because the front end of the instrument is Cantilever design, the rigidity of the instrument is poor. For thicker tissues, the abutment will be upturned and deformed, so that the front end anastomosis height H will become larger, and the left and right offset will also be caused, resulting in poor formation of the staples, unable to effectively match the tissue, affecting the operation. Quality, affecting the safety of surgery; In addition, for different tissues, the height of the anastomosis is different due to individual or tissue differences. Once the instrument is selected, the closed height of the prior art cannot be adjusted, so in clinical surgery, it is possible The crushed tissue, or the anastomotic height is too large, affecting the quality of surgery. These shortcomings have been found to be mainly due to design flaws in the closure device of the surgical linear cutting stapler.
