What feature distinguishes the Weislander self-retaining retractor?

The distinguishing feature of the Weislander self-retaining retractor is that its arms curve inwardly and have sharp teeth. This design is specifically intended to provide secure retraction of tissues during surgical procedures. The inward curve helps to facilitate access to the surgical area while the sharp teeth grip the tissue effectively, minimizing the risk of slippage and ensuring stability.

In contrast, other retractors may have different arm shapes or characteristics; for instance, flat arms with blunt tips do not provide the same level of tissue holding capability, while short arms without teeth may not be effective in maintaining adequate exposure. The unique inward curve combined with sharp teeth makes the Weislander retractor particularly suited for use in various veterinary surgical procedures, where adequate tissue retraction is crucial for visibility and access.
