To this end, the instrument has a smooth-surfaced, hooked tip that is ideal for firm and atraumatic grasping of skin and other tissues. In addition, the hook is equipped with a special mechanism that allows precise fixation in different planes. The product is made of high quality stainless steel, which allows sterilisation and reuse of the tool.
