Background and Aims

Many new through-the-scope clips are available, and physicians often select clips based on physical characteristics and/or cost. However, functional profiles may be equally important and have not been methodically assessed. We evaluated 5 commercially available clips: Resolution 360, Instinct, Quick Clip Pro, Dura Clip, and SureClip.

Methods

We rigorously compared clips on multiple characteristics, including rotatability, overshoot, open/close precision, and tensile/closure strength. Clips were tested in 4 different endoscope configurations: (1) straight, (2) duodenal sweep, (3) full retroflexion, and (4) across the duodenoscope elevator.

Results

For rotatability, the Resolution 360 was the fastest due to its unique functionality in allowing primary MD control in rotation (P < .05). The Resolution 360, SureClip, and Dura Clip were able to rotate through the prescribed sequence across all scope configurations. For overshoot, the SureClip and Resolution 360 had the least overshoot for the straight configuration at 0%. All clips had >75% overshoot at more strained configurations. For open/close precision, the SureClip and Dura Clip showed precise opening/closing with the ability to stop at any point. The remaining clips exhibited abrupt opening with more controlled closure. For tensile strength, the Quick Clip Pro generated the highest peak force as would be required in lateral tissue manipulation (4.8 lb, P < .005). For closure strength, the Instinct overall showed the most gel compression, and along with the Resolution 360, showed 100% deployment success for all gel tissue thicknesses (up to 10 mm).

Conclusions

Each clip has a unique physical and functional profile, which may be a factor in selection depending on the clinical circumstance.

选择合适的望远镜夹：将旋转性，鞭状，打开/闭合精度和闭合强度进行严格比较（带视频）

背景和目标

有许多新的可通过范围查看的剪辑，医生通常根据物理特性和/或成本来选择剪辑。但是，功能配置文件可能同等重要，尚未进行系统的评估。我们评估了5种市售剪辑：Resolution 360，Instinct，Quick Clip Pro，Dura Clip和SureClip。

方法

我们严格地比较了夹子的多种特性，包括可旋转性，过冲，打开/关闭精度和拉伸/关闭强度。在4种不同的内窥镜配置中对夹子进行了测试：（1）笔直，（2）十二指肠清扫，（3）完全后屈，以及（4）穿过十二指肠镜升降器。

结果

在旋转性方面，Resolution 360是最快的，这是因为它具有独特的功能，可以进行主要的MD旋转控制（P  <.05）。360分辨率，SureClip和Dura Clip能够在所有示波器配置中按指定顺序旋转。对于过冲，SureClip和Resolution 360的直配置的过冲最小，为0％。在更紧张的配置下，所有片段的过冲都超过75％。对于开/关精度，SureClip和Dura Clip具有精确的开/关功能，并且可以随时停止。其余的夹子表现出突然的张开，并且闭合更加受控。对于拉伸强度，Quick Clip Pro产生了最大的峰值力，这是在侧面组织操作中所需要的（4.8磅，P <.005）。对于闭合强度，Instinct整体显示出最大的凝胶压缩力，并且与Resolution 360一起，显示了所有凝胶组织厚度（最大10 mm）的100％部署成功。

结论

每个夹子具有独特的物理和功能特征，这可能是根据临床情况进行选择的一个因素。
