摘要:
The present invention provides endoscope scissors with which it is possible to exactly incise targeted body tissue, without slipping of a scissor element, and with which minimally-invasive procedures are possible without having to make incisions at an excessive depth such as, for example, those reaching the muscle layer. These endoscope scissors (100), which are inserted into a forceps hole of an endoscope for use to incise body tissue, are provided with an operation wire (30), and a pair of scissor elements (12, 22) that are overlaid one facing the other and are pivotally supported by a rotational shaft (29) so as to be able to open and close, the rotational shaft extending in a direction of overlay. The pair of scissor elements (12, 22) each have a cutting part (13, 23), respectively, for gripping and incising body tissue. At a distal end part of at least one of the pair of scissor elements (12, 22), a claw part (14) for gripping the body tissue is formed so as to protrude out further in a closing direction than the cutting part (13). Recesses (15, 25) that penetrate through in the thickness direction are formed locally at the cutting parts (13, 23), respectively, of the scissor elements (12, 22), and the cutting parts (13, 23) excluding the claw part (14) and the recesses (15, 25) are formed in a flat, linear shape extending in the tip-to-base direction.La présente invention concerne des ciseaux d'endoscope permettant d'inciser avec précision des tissus corporels ciblés, sans qu'un élément des ciseaux ne glisse, et permettant de réaliser des interventions chirurgicales non effractives sans avoir à pratiquer d'incisions à une profondeur excessive telles que, par exemple, celles atteignant la couche musculaire. Ces ciseaux (100) d'endoscope, qui sont insérés dans un orifice pour forceps d'un endoscope destiné à être utilisé pour inciser des tissus corporels, sont dotés d'un fil d'actionnement (30), et d'une paire d'éléments (12, 22) de ciseaux qui sont superposés,
