Use of the OTSC® Anchor

The OTSC® Anchor can be used for better approximation of tissue especially when indurated (e.g. fistulae, chronic ulcer). It also facilitates targeting of lesions, e.g. in the treatment of hemorrhage, the OTSC® Anchor allows precise alignment between the target tissue and the applicator cap.

The OTSC® Anchor is available in two versions and lengths:

  • The OTSC® Anchor has a flexible shaft length of 165 cm
  • The OTSC® Anchor 220 tt has a flexible shaft length of 220 cm and is especially for thin tissue

Application

Hemostasis with anchor technique

In cases of fibrotic or hard tissue (e.g. callous ulcers) or tangential application, the OTSC® Anchor can be valuable in precisely aligning target tissue with the cap opening and keeping it fixed during clip release. It may not always be possible to manipulate fibrotic tissue fully inside the cap. However, it is sufficient to pull the tissue firmly to the rim of the cap with the OTSC® Anchor, then apply the clip. The clip “jumps” slightly forward upon release and grasps the tissue in front of the cap.
