Hand assisted laparoscopic Seal Assembly with a Ratchet mechanism

摘要

A Seal Assembly (also called 'unit' Or 'Sealing Structure sealing') that can be used in Hand assisted laparoscopic procedures,That includes: a Sealing cap or cover (12) which contains a Seal (also known as the 'board', 'Close' Or 'seal') (16) located in a FrameSo the frame (18) contains a Lower Sealing ring (28) that has a track or path (30) that supports an Upper Sealing ring (32) to make a Movement of rotationOn,So that the Seal is held between the upper ring and the lower Sealing Ring Sealing to make possible a shift or rotation between an open and a closed orientation and guidance;A Ratchet mechanism (or Zipper mechanism) (48) that controls the Movement of the Upper Sealing ring in connection with the bottom Ring SealingIt is characterized by the fact that the track or Trail includes an annular Inner Wall Straight (30a) and an annular outer wall line (30b) which are connected through a component base30) so that the Ratchet mechanism includes an arm (called 'Ratchet arm') (66) that is oriented to join or be attached to the surface of the Ratchet;The surface of the Pawl (68th, b) is situated between the annular Inner Wall and the Outer annular Wall Straight Straight.
