AI Technical Summary
Technical Problem
After implantation of an artificial anal sphincter device, it can compress the mesentery, affecting blood circulation and nutrient supply to the intestines, leading to serious complications.
Method used
A silicone implantation device was designed, comprising a silicone body, a deformable skeleton, and control components. The silicone body has an avoidance channel, and the deformable skeleton is driven to switch states by an electroactive material to avoid compression of the mesentery. Precise control is achieved through sensors and a power supply unit.
Benefits of technology
This effectively avoids mesenteric compression, reduces the incidence of serious postoperative complications, and ensures normal blood supply and functional recovery of the intestines.

Abstract
本发明涉及医疗器械技术领域，具体涉及了一种用于替代肛门括约肌的硅胶植入装置，包括硅胶主体、变形骨架和控制组件。硅胶主体套设在肠管外部，且具有限制物质排出的第一状态和允许物质排出的第二状态。硅胶主体的侧壁沿自身轴线延伸有避让通道，在硅胶主体套设在肠管的过程中，肠系膜能够进入避让通道内。变形骨架被包裹在硅胶主体内部，变形骨架能够发生形变以驱动硅胶主体进行状态切换。控制组件用于接收外部信号并控制变形骨架的形变。由此，通过将肠系膜放置在避让通道内，能够在硅胶主体进行状态切换时，防止硅胶主体卡压肠系膜，保障肠管的正常血供，避免肠管血供障碍及由此引发的肠管坏死。
