New tumor clips for the removal of large or deep-seated tumors: technical note.


:We describe newly developed tumor-holding clips, which have been applied in more than 50 patients with large or deep-seated tumors. We devised various kinds of standard tumor clips by modifying Sugita aneurysm clips. Our new tumor clips permit gentle, steady, and easy retraction of the tumor in any direction without disturbance of the operative field. With the use of these clips, a surgeon can operate with both hands. From our experience of removing more than 50 tumors, we confirm that our tumor clips are useful for the removal of large or deep-seated tumors.
