LineR ReviSion If it is necessary to remove the liner from the cup, the liner removal tool can be used to open the ring and then lever out the liner. To remove a liner, insert the liner removal tool into the cup as shown in Figures 10, 11 and
As such, a liner hanger provides a means to anchor the next smallest diameter casing/liner to the lowermost end of a previously installed length of casing. A seal is required at the top of the liner hanger to prevent the transfer of fluid or pressures from either direction (Halliburton.com 2018). There are two types of liner hangers: expandable liner

Description: The Trilogy Constrained Liner is a polyethylene liner assembly used in conjunction with a Trilogy Acetabular System metal shell in total hip arthroplasty procedures.The liner consists of two pieces: a liner and a constraining ring. The liner is manufactured from ultra-high molecular-
polyethylene liner until it is fully flush with the face of the liner (Fig. 3). Step 2: Removal of Metal Shell Hold the removal tool against the liner (do not allow the tool to rotate). Twist and pull the metal shell away from the liner. The tool must remain flush with the liner while the shell is being re
