This invention belongs to the field of building emergency evacuation technology, specifically disclosing a method for the safe evacuation of personnel in deep underground buildings and their clusters, combining vertical and horizontal elements. Based on the concept of a shared safety zone in deep underground buildings, it proposes a method for three streams of people to evacuate simultaneously in the stairwell in an "upward-downward-upward" manner. The building is divided into three evacuation spaces of equal level (upper, middle, and lower), with two evacuation direction conversion points and one shared safety zone. Personnel in the upper evacuation space evacuate upwards to the ground via the nearest evacuation direction conversion point. Personnel in the middle and lower evacuation spaces evacuate via the second evacuation direction conversion point, leading to the shared safety zone. This provides a deep underground building cluster technology with an infinitely scalable and resilient evacuation network, forming a new design and planning method. The advantages of this invention are: extremely compressed total evacuation time, significantly improved reliability of underground spaces under extreme disasters, and the realization of intensive and sustainable development.

This invention provides a control suture reel, a suture hole handle, and a ligator, relating to the field of medical device technology. The control suture reel rotates in a first direction to wind up the suture and drive the working part. It has at least one locking part circumferentially, each locking part comprising a trigger locking position and a pre-tensioning locking position arranged sequentially in opposite directions: when the trigger locking position is locked, the corresponding ligature loop is released; when the pre-tensioning locking position is locked, the suture is wound up and tensioned. This dual-locking structure achieves physical separation and timing control of tensioning and triggering, eliminating redundant bending, restoring the straightness of the release suture, and avoiding obstruction of vision and tissue adhesion. The pre-tensioning stage provides disturbance-free correction of the suture posture, and the triggering stage initiates with low inertia, significantly suppressing mechanical tissue damage caused by vibration and slippage. It improves the reliability, safety, and ergonomics of multi-turn sequential release, meeting the needs of high-precision, low-invasive endoscopic interventional treatment.
