A new cholangiograsper cannula was developed through which a Fr 4 or 5 ureteric cannula can be advanced into the incised cystic duct and held in a water-tight position. This instrument facilitates intraoperative cholangiography. A plastic trocar stylet eliminates the metal shadow of the trocar during cholangiography. A new "laparocamera" is described where camera and telescope are built together in one unit decreasing the need for additional manipulation during the procedure. A camera holder driven by air helps the operator to keep his/her hands free. The need for a third assistant is avoided by inserting the camera into a (presterilized) holder, the position of which is controlled by press buttons.
一种新型胆管抓取套管已研发出来，通过它可将4F或5F输尿管套管推进切开的胆囊管并保持水密状态。该器械便于术中胆管造影。一种塑料套管针芯可消除胆管造影时套管针的金属阴影。描述了一种新型“腹腔镜摄像机”，其摄像头和望远镜集成在一个单元中，减少了手术过程中额外操作的需求。由空气驱动的摄像头固定器可帮助操作者解放双手。将摄像头插入一个（预先消毒的）固定器中，通过按钮控制其位置，从而避免了对第三名助手的需求。
