A testing device (38) for detecting defects in insulation (126) of electrosurgical instruments that includes an implement or wand (14) having a distal end (72), an electrode (20) for generating a spark adapted to detect a defect (200) in the insulation, and mounting means (92) for removably mounting the electrode to the distal end of the implement. The removable mounting means includes a shank (86) that is received in a socket or bore (82) defined in the distal end of the wand and is engageable with the wand within the socket so the shank can easily be removed from the socket after use. The wand is releasably engageable with the housing (12) by a flexible bracket (50) that extends from the housing. The device (10) may include a pad (100) having a reflective top surface (106) with ridges (108) upon which the surgical instrument to be tested is placed.

Ce dispositif (38) d'essai permet de détecter des défauts dans l'isolation (102) d'instruments électrochirurgicaux, et il comprend un accessoire ou baguette (14) présentant une extrémité (72) distale, une électrode (20) permettant de produire une étincelle destinée à détecter un défaut (200) d'isolation, et une pièce (92) de montage permettant le montage réversible de cette électrode sur l'extrémité distale de l'accessoire. La pièce de montage amovible présente une tige (86) reçue dans une douille ou un trou (82) défini dans l'extrémité distale de la baguette et pouvant s'emboîter avec la baguette dans la douille, de façon qu'on puisse facilement retirer ladite tige de la douille après utilisation. La baguette peut entrer en prise réversible avec le boîtier (12) grâce à un support (50) souple partant de ce dernier. Ce dispositif (10) peut comprendre un plateau (100) à surface supérieure (106) réfléchissante comportant des nervures (108) sur lesquelles on place l'instrument chirurgical à essayer.
