One holding arrangement includes a body portion, an engagement barrel and a retaining member configured as a hook at a distal end of the body portion. The engagement barrel is position on a proximal end of the body portion and is configured to be selectively rotated about the body portion when operatively connected to a surgical holding arrangement. A rotation brake is mounted on the body section. The rotation brake is selectively operable to lock the engagement barrel against rotation. ## Claims ### Claim 1 A selectively lockable holding assembly for a surgical access assembly, comprising: a body portion; an engagement barrel; a retaining member at a distal end of the body portion; wherein the engagement barrel is positioned on the body portion and configured to be selectively rotated about the body portion; and a rotation brake mounted on the engagement barrel, wherein the rotation brake is selectively operable to lock the engagement barrel against rotation with respect to the body portion, wherein the rotation brake comprises a leg, and a selectively turnable brake lever having a main body section and opposing finger tabs extending outwardly therefrom, wherein sloped members are disposed on a top surface of the main body section, a groove is disposed between the sloped members, and the opposing finger tabs are rotatable to cause the sloped members to engage against the leg. ### Claim 2 (depends on 1) The holding assembly of claim 1, further comprising a Sugita adapter mounted to the engagement barrel. ### Claim 3 (depends on 2) The holding assembly of claim 2, wherein the Sugita adapter further comprises a body portion and a mounting area, wherein the mounting area further comprises a mounting sleeve. ### Claim 4 (depends on 3) The holding assembly of claim 3, wherein the mounting sleeve further comprises a mounting channel therethrough that receives the engagement barrel. ### Claim 5 (depends on 1) The holding assembly of claim 1, further comprising a Budde adapter mounted to the engagement barrel. ### Claim 6 (depends on 5) The holding assembly of claim 5, wherein the Budde adapter includes a body portion formed as a mounting sleeve and including a mounting channel therethrough that receives the engagement barrel. ### Claim 7 (depends on 6) The holding assembly of claim 6, further comprising a mounting area that includes a support groove, wherein the support groove does not extend through the mounting area and receives a support shaft therein. ### Claim 8 (depends on 7) The holding assembly of claim 7, wherein the support shaft is defined by a first end and second end and wherein the first end is formed with at least one support ring and an annular recess, wherein the support ring frictionally engages sidewalls of the support groove to secure the support shaft to the Budde adapter. ### Claim 9 (depends on 1) The holding assembly of claim 1, wherein the retaining member further includes a treated section that is configured to reduce glare. ### Claim 10 A selectively lockable holding assembly for a surgical access assembly, comprising: a body portion; an engagement barrel; a retaining member at a distal end of the body portion; wherein the engagement barrel is positioned on the body portion and configured to be selectively rotated about the body portion; and a rotation brake mounted on the engagement barrel and receiving the body portion, wherein the rotation brake is selectively operable to frictionally grip the body portion to lock the engagement barrel against rotation with respect to the body portion, wherein the rotation brake comprises a leg, and a selectively turnable brake lever having a main body section and opposing finger tabs extending outwardly therefrom, wherein sloped members are disposed on a top surface of the main body section, a groove is disposed between the sloped members, and the opposing finger tabs are rotatable to cause the sloped members to engage against the leg. ### Claim 11 (depends on 10) The holding assembly of claim 10, further comprising a Sugita adapter mounted to the engagement barrel. ### Claim 12 (depends on 11) The holding assembly of claim 11, wherein the Sugita adapter further comprises a body portion and a mounting area, wherein the mounting area further comprises a mounting sleeve. ### Claim 13 (depends on 12) The holding assembly of claim 12, wherein the mounting sleeve further comprises a mounting channel therethrough that receives the engagement barrel. ### Claim 14 (depends on 10) The holding assembly of claim 10, further comprising a Budde adapter mounted to the engagement barrel. ### Claim 15 (depends on 14) The holding assembly of claim 14, wherein the Budde adapter includes a body portion formed as a mounting sleeve and including a mounting channel therethrough that receives the engagement barrel. ### Claim 16 (depends on 15) The holding assembly of claim 15, further comprising a mounting area that includes a support groove, wherein the support groove does not extend through the mounting area and receives a support shaft therein.
