Abstract:
1. A lock assembly for use in conjunction with a trocar sleeve to lock an instrument passing therethrough in position relative to the trocar sleeve, the lock assembly comprising: a lock assembly housing having an aperture extending therethrough; a cam lever and an elastomeric block positioned within the lock assembly housing, the cam lever includes a first end pivotally secured to the lock assembly housing and a free second end that is external of the housing and is adapted for user actuation, the cam lever being moveable between a locking position in which the cam lever is rotated inwardly for retaining an instrument to prevent undesired motion of the instrument relative to the trocar sleeve and a release position in which the cam lever is rotated outwardly and is not in contact with the elastomeric block; the cam lever includes a camming surface adjacent the first end of the cam lever, the camming surface being shaped and dimensioned for selectively engaging the elastomeric block for engagement with an instrument passing though the lock assembly housing; and wherein rotation of the cam lever to the locking position brings the camming surface of the cam lever into contact with the elastomeric block that ultimately brings the elastomeric block into engagement with an instrument passing through the lock assembly housing for locking an instrument relative thereto.
