Suture clip deployment devices

Disclosed herein are suture clip delivery devices that can be loaded with several flat, disk-shaped suture clips and can deploy the suture clips one after another onto respective sutures without reloading the device with additional suture clips. An exemplary device includes a handle portion with an actuation mechanism that is coupled to a shaft portion that holds and deploys the suture clips. The shaft portion includes a mandrel on which the suture clips are mounted and a retainer that restricts the suture clips from moving proximally when the actuation mechanism pulls the mandrel proximally, which causes a distal-most suture clip to slide off the mandrel and be deployed onto one or more suture. The mandrel and remaining suture clips can them move distally to prepare to deploy the next suture clip. 本文公开了缝合夹递送装置，其能够装载有若干平坦的盘形缝合夹，并且能够将缝合夹个接个地部署到相应的缝合线上，而不用另外的缝合夹重新装载装置。示例性装置包括具有致动机构的手柄部分，该致动机构耦接到保持和部署缝合夹的轴部分。轴部分包括其上安装有缝合夹的心轴和固位器，该固位器在致动机构向近侧拉动心轴时限制缝合夹向近侧移动固位器，这使最远侧缝合夹滑出心轴并被部署到个或多个缝合线上。心轴和剩余的缝合夹然后能够向远侧移动以准备部署下缝合夹
