• 1. a lavage fluid tube hub (84), extending from said first surface (81) and dimensioned to receive an inner lavage fluid tube (60, 560) and being within liquid communication with said inner lavage fluid tube (60, 560) through a lavage fluid orifice (85);
• and
• 2. lavage fluid openings (86) in fluid communication with said hollow body (20) to enable lavage fluid drainage;
• ii. a lavage fluid hub (90), said lavage fluid hub (90) extending from said second surface of said body hub (83) and being in liquid communication with said tube hub (84) through a lavage fluid inlet channel (92);
• iii. a lavage fluid hub (89), said lavage fluid hub (89) containing a lavage fluid channel (91) in liquid communication with said hollow body (20) and a lavage fluid chamber (94);
• iv. a lavage fluid inlet channel (92) in liquid communication with said lavage fluid tube hub (84);
• v. an upper connecting lavage fluid orifice (87), said upper connecting lavage fluid orifice (87) permitting liquid communication between said lavage fluid connecting tube (50) and said lavage fluid inlet channel (92) and a radial lavage fluid inlet channel (92′);
• d. a lavage fluid connecting tube (50), said lavage fluid connecting tube (50) having a first end in liquid communication with said first end of said hollow body (20) at said brush adaptor (40, 540) and a second end in liquid communication with said hollow body (20) through said upper connecting lavage fluid orifice (87);
• e. an inner lavage fluid tube (60, 560), said inner lavage fluid tube (60, 560) extending within said hollow body (20) and having:
• i. a distal end (61) in liquid communication through an inner channel (64) with said hollow body (20);
• ii. a proximal end (63) in liquid communication through said inner channel (64) with said interior of said inlet adaptor (80);
• iii. a tube brush (70) at said distal end (61);
• and
• iv. multiple inner spray e openings (62) at said distal end (61).

A method for cleaning cannulated tools using a cleaning apparatus having a hollow body (20) with lavage fluid holes (22) at a first end, a brush adaptor (40) affixed at said first end of said hollow body (20), an inlet adaptor (80) at a second end of said hollow body (20), and an exterior lavage fluid tube (50) having a first end in liquid communication with said hollow body (20) through said brush adaptor (40) and a second end in liquid communication with said hollow body (20) through said inlet adaptor comprising the steps of:

• a. attaching a distal end of a lavage fluid tube from a lavage fluid source to a lavage fluid hub (90) on said inlet adaptor (80);
• b. attaching a distal end of a lavage fluid fluid tube to a lavage fluid hub (91) on said inlet adaptor (80);
• c. attaching a proximal end of an inner lavage fluid tube to said lavage fluid hub (90);
• d. attaching a disk brush (30) having bristles to said brush adaptor (40) opposite said hollow body (20);
• e. attaching a brush (70) to a distal end of said inner lavage fluid tube;
• f. inserting a cannulated tool to be cleaned through said disk brush (30);
• g. inserting said cannulated tool over said brush (70);
• h. causing lavage fluid from said lavage fluid source to enter said lavage fluid hub (90) and enter an inlet channel (92) and into said inner lavage fluid tube;
• i. causing lavage fluid from said inner lavage fluid tube (60) to exit holes (62) and spraying an interior surface of said cannulated tool;
• j. causing lavage fluid to flow to enter said lavage fluid hub (90) and enter a radial lavage fluid inlet channel (92′) and flow along a lavage fluid connecting tube (50);
• k. causing lavage fluid to enter said brush adaptor (40) from said lavage fluid connecting tube (50) and exit holes within said brush adaptor (40);
